Technical Field

[0001] Various embodiments generally relate to computer peripheral devices. In particular, various embodiments generally relate to computer peripheral devices (such as headsets and microphones) including one or more light display units for live broadcast, and methods of controlling the light display unit(s) of the computer peripheral devices.

Background

[0002] Live streaming or broadcasting platforms (e.g. Twitch, Douyu, Huya, Mixer, Facebook and Youtube) are widely used by different users nowadays to broadcast various types of activities and/or messages. For example, some users (broadcasters) utilize the broadcasting platforms while playing games to broadcast not only the gameplay, but also themselves during the gameplay to for example, provide commentaries to the game. Some other users employ the broadcasting platforms to provide information or market certain products. Several broadcasting platforms also provide viewers of the broadcasts a variety of response mechanisms so that the viewers may share their thoughts on the broadcasts. For example, the viewers can click a button to follow the broadcaster’s live broadcast channel or send a chat message to the broadcaster. The activation of one of the response mechanisms by a viewer may be referred to as an action and the broadcaster may receive a notification from the broadcasting platform whenever an action occurs.

[0003] It is often challenging to achieve timely interaction between the broadcasters and the viewers, or between different viewers during a broadcast. For example, there is usually a delay between the occurrence of an action and the time at which the broadcaster or another viewer knows about this occurrence. This is because the notifications received by the broadcasters and viewers when an action occurs are usually in the form of sound notifications, screen notifications or lighting cues which are not easily noticeable by the broadcasters and viewers during the live broadcast.

[0004] Accordingly, there is a need for methods and devices to improve the interaction between the broadcasters and the viewers during a live broadcast. Summary

For example, the headset 200 may include a single one of the light display units 216, 218, 224, 226 or may include more than four light display units. For example, the headset 200 may include only the first light display unit 216 or only the second light display unit 218. \

[00030] FIG. 3 A shows a front view of a microphone 300 according to various embodiments. FIGS. 3B to 3D respectively show a first side view (right view), a back view and a second side view (left view) of the microphone 300. FIG. 3E shows an exploded view of a part of the microphone 300.

[00031] In various embodiments shown in FIGS. 3A-3E, the microphone 300 may include a base 302 where a height of the base 302 may be adjustable. The base 302 may further include an elastic element (such as a spring) to enable the adjustment of the height of the base 302.

[00032] The microphone 300 may further include a sound receiving element 304. In one example embodiment, the sound receiving element 304 may be attached to the base 302 through a sound receiving element body 306 as shown in FIG. 3E. The sound receiving element body 306 may include first, second and third holders 306a, 306b, 306c. The first holder 306a may have a hole configured to receive the sound receiving element 304 and the second holder 306b may be configured to support the first holder 306a. The third holder 306c may include a hollow cylinder 306d and one or more engaging members (such as rings) arranged on the hollow cylinder 306d. The third holder 306c may further include holes configured to receive control buttons 310, 312. The microphone 300 may further include at least one light display unit, where the at least one light display unit may be substantially similar to the light display unit 100 of FIG. 1. For example, as shown in FIG. 3E, the microphone 300 may include a light display unit 318 having a matrix of independently controllable light emitting elements 318a (such as LEDs). In some embodiments, the matrix of light emitting elements 318a of the light display unit 318 may have a size bigger than a size of the sound receiving element 304. As one example, the light emitting elements 318a are arranged in an NxM matrix wherein N and M are integers greater than or equal to one. For example, the matrix of light emitting elements 318a of the light display unit 318 may include eight rows and eight columns. However, in other embodiments, the matrix of light emitting elements 318a of the light display unit 318 may be of a different size. The light display unit 318 may be attached to a light display holder 320 by light display engaging elements 322 (such as screws), and the light display holder 320 may in turn be connected with the second holder 306b of the sound receiving element body 306. Accordingly, the light display unit 318 may be attached to the base 302 via the light display holder 320 and the sound receiving element body 306. In various embodiments, the microphone 300 may further include a light diffusing element 324 arranged adjacent to the light display unit 318, where the light diffusing element 324 may be configured to diffuse light projected from the light display unit 318.

[00033] In various embodiments, the microphone 300 may further include a shielding element 326. The shielding element 326 may be attached to the base 302 in one example embodiment. In various embodiments, a casing 328 configured to hold the shielding element 326 may be arranged with the sound receiving element body 306 and the light display holder 320. In various embodiments, the light display unit 318 may be arranged at least partially between the sound receiving element 304 and the shielding element 326 and may be arranged such that the matrix of light emitting elements 318a project light towards the shielding element 326. For example, as shown in FIG. 3E, the light display unit 318 may be arranged partially between the sound receiving element 304 and the shielding element 326. The light display unit 318 may be arranged at the back side 300b of the microphone 300 and the light emitting elements 318a may project light towards the back side 300b of the microphone 300.

[00034] In various embodiments, the microphone 300 may further include a microphone receiver configured to receive data from a processor-based device and a microphone control unit configured to control the light emitting elements 318a of the light display unit 318 based on the data received by the microphone receiver. In various embodiments, the microphone receiver may be a controller element or an antenna. However, in alternative embodiments, the microphone receiver may be any other type of receiver capable of receiving wireless data, or may be a cable having a connector configured to connect to the processor-based device. Control buttons 310 and 312 may also be provided on the controller element. [00035] In various embodiments, the light display unit 318 may be configured to display a still graphic (e.g. a logo) or an animation (e.g. animated graphic or light effects). As mentioned above, the light display unit 318 may be substantially similar to the light display unit 100 described in FIG. 1. In other words, the light emitting elements 318a of the light display unit 318 may be independently controllable. Further, each light emitting element 318a of the light display unit 318 may be configured to adopt one or more states out of a plurality of states, where the state of each light emitting element 318a may represent one or both of a color of the light emitting element 318a and a brightness of the light emitting element 318a. In various embodiments, the data received by the microphone receiver may include at least one state for each light emitting element 318a of the light display unit 318, and the microphone control unit may be configured to adjust each light emitting element 318a of the light display unit 318 according to the at least one state provided in the data for the respective light emitting element 318a. In some embodiments, the data received by the microphone receiver may represent a still graphic. In these embodiments, the received data may include a single state for adjusting each light emitting element 318a of the light display unit 318. In other embodiments, the data received by the microphone receiver may represent an animation (e.g. an animated graphic or light effects). In these embodiments, the received data may include a sequence of states for each light emitting element 318a of the light display unit 318, and the microphone control unit may be configured to adjust each light emitting element 318a to adopt the states provided in the data, where an order in which each light emitting element 318a adopts the states corresponds to the sequence of the states provided in the data.

[00036] Although the light display unit 318 is depicted as being arranged at the back side 300b of the microphone 300 in FIG. 3E, in other embodiments, the light display unit 318 may be arranged at the front side 300a of the microphone 300 In alternative embodiments, the light emitting elements 318a of the light display unit 318 may be arranged along a boundary of an intermediate surface that may surround the sound receiving element 304. In one example, the light emitting elements 318a of the light display unit 318 may be arranged on the entire intermediate surface. Further, although the microphone 300 is depicted as having a single light display unit 318 in FIG. 3E, the microphone 300 may have further light display units substantially similar to the light display unit 100 and controllable by the microphone control unit on the controller element 334. For example, the microphone 300 may have a light display unit (first light display unit) and a further light display unit (second light display unit) arranged on opposite sides of the microphone 300. For example, the first light display unit may be arranged at the front side 300a of the microphone 300 and the second light display unit may be arranged at the back side 300b of the microphone 300. In various embodiments, the microphone control unit may be configured to independently control the light emitting elements of the first light display unit and the second light display unit, respectively. In some embodiments, the microphone 300 may include further light display units arranged on the base 302 or on the sound receiving element body 306, where these further light display units may also be substantially similar to the light display unit 100. The further light display units may also be controllable by the microphone control unit on the controller element, either independently in some embodiments or together in other embodiments.

[00037] During a live broadcast, a broadcaster may use a live broadcast system including a first processor-based device and one or more computer peripheral devices configured to connect to the first processor-based device of the broadcaster. In various embodiments, the first processor-based device may be a host computer or a computing device on which applications may be run. In various embodiments, the one or more computer peripheral devices may include a video capturing device, such as a web camera, to capture a video of the broadcaster and his/her surroundings. In various embodiments, the one or more computer peripheral devices may further include devices having one or more light display units substantially similar to the light display unit 100. For example, the one or more computer peripheral devices may further include the headset 200 of FIGS. 2A to 2B and/or the microphone 300 of FIGS. 3 A to 3E. For example, the broadcaster may use the headset 200 to receive sound notifications from a broadcasting platform running on the first processor-based device and may also use the microphone 300 to amplify his/her voice so that his/her voice is more audible to viewers watching the live broadcast. During the live broadcast, the broadcaster may wear the headset 200 such that the third and fourth light display units 224, 226 face the video capturing device. Further, the broadcaster may arrange the microphone 300 such that the light display unit 318 faces the video capturing device. For example, if the light display unit 318 is arranged at the back side 300b of the microphone 300 (as shown in FIG. 3E), the broadcaster may arrange the microphone 300 such that the backside 300b of the microphone 300 faces the video capturing device. Accordingly, viewers of a live broadcast by the broadcaster may be able to see light projected from the light display units 216, 218, 224, 226 of the headset 200 and the light projected from the light display unit 318 of the microphone 300. In various embodiments, the light projected from each light display unit 216, 218, 224, 226, 318 may depend on the states of the light emitting elements 216a, 218a, 224a, 226a, 224b, 226b, 224c, 226c, 318a of the light display units 216, 218, 224, 226, 318. [00038] Several aspects of controlling light display units of one or more computer peripheral devices will now be presented with reference to various apparatus and methods. These apparatus and methods will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as“elements”). These elements may be implemented using electronic hardware, computer software, or any combination thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.

[00039] By way of example, an element, or any portion of an element, or any combination of elements may be implemented as a“processing system” that includes one or more processors. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs), central processing units (CPUs), application processors, digital signal processors (DSPs), reduced instruction set computing (RISC) processors, systems on a chip (SoC), baseband processors, field programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gated logic, discrete hardware circuits, and other suitable hardware configured to perform the various functionality described throughout this disclosure. One or more processors in the processing system may execute software. Software shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software components, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, etc., whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise.

[0001] Accordingly, in one or more example embodiments, the functions described may be implemented in hardware, software, or any combination thereof. If implemented in software, the functions may be stored on or encoded as one or more instructions or code on a computer-readable medium. Computer-readable media includes computer storage media. Storage media may be any available media that can be accessed by a computer. By way of example, and not limitation, such computer-readable media may include a random- access memory (RAM), a read-only memory (ROM), an electrically erasable programmable ROM (EEPROM), optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of the aforementioned types of computer-readable media, or any other medium that can be used to store computer executable code in the form of instructions or data structures that can be accessed by a computer. [00040] In various embodiments, the broadcaster may be able to select or design still graphics or animations (such as animated graphics or light effects) to be displayed on the one or more light display units of the one or more computer peripheral devices. The still graphics or animations may include emoji’s, logos, or other images. The still graphics or animations may be displayed on the one or more light display units in response to particular events during a live broadcast. Accordingly, viewers of a live broadcast by the broadcaster may see the still graphics or animations during the live broadcast.

[00041] In various embodiments, the broadcaster may determine the still graphics or animations to be displayed on each light display unit and the type of events that trigger the display of each still graphic or animation, by providing user input to his/her first processor- based device prior to the live broadcast.

[00042] FIG. 4 shows a flow chart of a method 400 for obtaining and storing user input from a broadcaster (or in other words, a user) prior to a live broadcast, where the user input may be for controlling the one or more light display units of the one or more computer peripheral devices (e.g. light display unit 216, 218, 224, 226 of the headset 200 or light display unit 318 of the microphone 300). Each light display unit may include a matrix of independently controllable light emitting elements and each light emitting element of each light display unit may be configured to adopt one or more states out of a plurality of states. The method 400 may be performed by the first processor-based device of the broadcaster, where the first processor-based device may be operative to run an application configured to obtain the user input. FIGS. 5 A to 5B show a graphical user interface (GUI) of an example application that may be run by the first processor-based device for obtaining the user input.

[00043] As shown in FIG. 4, at 402, a user input unit of the first processor-based device may obtain user input from a broadcaster prior to a live broadcast. The implementation of 402 will be discussed below with reference to FIGS. 5 A to 5B. At 404, the user input may be stored in the first processor-based device, for example in a computer readable medium/memory of the first processor-based device.

[00044] At 402, user input may be obtained for multiple types of events and the user input for each type of event may indicate the following: (i) one or more light display units to be changed upon occurrence of the type of event; and (ii) an adjustment to be made to each light emitting element of each light display unit to be changed.

[00045] For example, an application with a graphical user interface (GUI) may provide a platform for obtaining the user input indicating the above-mentioned (i) one or more light display units to be changed upon occurrence of each type of event. [00046] The user may first be presented with a“DASHBOARD” interface of the GUI when the first processor-based device runs the example application. The application may provide an instruction message to the broadcaster on the“DASHBOARD” to navigate to an“ALERTS” interface to provide user input.

[00047] In various embodiments, the user input unit of the first processor-based device may obtain user input for one type of event separately from user input for another type of event. For example, in various embodiments, the processor-based device may obtain user input indicating one or more light display units to be changed/controlled upon occurrence of one type of event separately from user input indicating one or more light display units to be changed/controlled upon occurrence of another type of event. By way of example, at the “ALERTS” interface, the application may provide a list of categories of events. This may include for example, a“Follows” category, a“Subscriptions” category, a“Cheer” category, a “Chat Message” category, a“Whisper” category, a“Host” category and a“Raid” category. The user may select one category of event each time and upon selection of a particular category of event, the user may be presented with an instruction message to provide one or more computer peripheral devices with light display unit(s) to be changed upon occurrence of a type of event in this category. In other words, the user input unit of the first processor-based device may obtain user input indicating the light display units to be changed upon occurrence of each type of event in each category. In various embodiments, the user may be further presented with a predetermined list of computer peripheral devices and the user may select one or more computer peripheral devices from this predetermined list. The computer peripheral devices in the predetermined list may be in different groups to facilitate the user’s selection. In some embodiments, the computer peripheral devices that may be selected by the user may be limited to those connected to the first processor-based device and the user may receive an error message if he/she tries to select an unconnected computer peripheral device. In some embodiments, the user may be presented with a warning message (e.g.“the more devices selected, the higher the processor usage”) to advise the user to select only the computer peripheral devices expected to be used during the live broadcast.

[00048] In various embodiments, the user input unit of the first processor-based device may obtain user input defining each type of event. For example, certain types of events may be defined as having occurred once an action has happened and these events may be defined without user input. For example, a“Follows” event and a“Subscriptions” event may be defined (in the“Follows” and“Subscriptions” categories) as having occurred when a viewer follows the broadcaster’s channel and subscribes respectively. However, certain types of events may be defined by user input, for example, user input indicating a condition such as a number of occurrences of an action. For example, the user may be presented with an instruction message (in the “Cheer”, “Chat Message”, “Whisper”, “Host” and“Raid” categories) requesting the user to define a“Cheer” event, a“Chat message” event, a“Whisper” event, a“Host” event and a“Raid” event based on a number of occurrences of a“cheer” action, a“chat message” action, a“viewing” action, or a“raid” action. In the“Chat Message” category, the types of“Cheer” events may alternatively be defined by a number of bits received from the viewers. For certain categories, the user may be presented with a further option, such as to indicate whether a type of event is defined for one or both of an“Auto Host” and a“Manual Host”. For some categories, different types of events may be defined in the same category based on different conditions which may or may not be user-defined. For instance, different types of events in a category may be defined based on a different number of occurrences of an action. For example, different types of“Whisper” events may be defined in different tabs based on a different number of occurrences of a“chat message” action (each action indicated by presence of a chat line). The broadcaster may be presented with a drop-down box with selectable values and/or may indicate any number (even if the number is not in the drop down box) to define the type of event. Different types of events may also or alternatively be defined in the same category based on characteristics of the actions related to the category. By way of example, different types of events may be defined in different tabs of the“Subscriptions” category based on whether the“subscription” action is a normal/general subscription, a resubscription or a gifted subscription.

[00049] In various embodiments, the user input unit of the first processor-based device may obtain user input indicating whether to change any light display unit upon occurrence of a type of event. For instance, the user may be presented with a toggle button for each category in the example application, where the status of the toggle button for that category may indicate whether to change any light display unit upon occurrence of all types of events in that category. For example, if the toggle button is indicated as“on” during a live streaming, the processor- based device may change one or more light display units when a viewer follows or subscribes to the broadcaster’s channel but if the toggle button is indicated as“off’, the one or more light display units may not be changed when a viewer follows or subscribes. By way of example, more than one type of event may be defined, the user may be provided with another toggle button for each type of event to indicate whether to change one or more light display units upon occurrence of that type of event. [00050] The GUI of the example application may obtain the user input indicating the above- mentioned (ii) adjustment to be made to each light emitting element of each light display unit to be changed. In various embodiments, user input indicating this may include at least one set of states for adjusting the light emitting elements of the light display unit. In various embodiments, each state may represent one or both of a colour of the light emitting element and a brightness of the light emitting element.

[00051 ] In various embodiments, the user input unit of the first processor-based device may obtain user input indicating, for a type of event and for a light display unit to be changed upon occurrence of the type of event, one of a plurality of predetermined light display outputs. The predetermined light display outputs may include preset still graphics or animations such as light effects or animated graphics, and may be stored in the first processor-based device, for example, in a computer readable medium/memory of the first processor-based device. In various embodiments, each predetermined light display output may include at least one set of states for adjusting the light emitting elements of the light display unit. In some embodiments, at least one predetermined light display output may include multiple sets of states for adjusting the light emitting elements of the light display unit and a time instance for each set of states. For example, a plurality of predetermined light display outputs can be stored in the application, and an instruction message can be sent to the user to select one of these predetermined light display outputs as the light display output to be displayed on a light display unit upon occurrence of a type of event. Same or different predetermined light display outputs may be selected for different types of events. In various embodiments, the light display outputs may be referred to as Chroma lighting effects. In various embodiments, the predetermined light display outputs may be referred to as quick effects and may include effects such as“Wave”, “Fire”,“Reactive”,“Ripple”,“Spectrum Cycling”,“Starlight”,“Static”,“Breathing”,“W heel” and“blinking” effects as known to those skilled in the art. In various embodiments, instead of selecting from the“EDITOR” interface, the user may be presented with an option to upload a predetermined light display output as the light display output to be displayed upon occurrence of a type of event. For example, the user may upload a predetermined logo, image or gif animation.

[00052] In various embodiments, the user input unit of the first processor-based device may obtain user input indicating, for a type of event and for a light display unit to be changed upon occurrence of the type of event, at least one set of states for adjusting the light emitting elements of the light display unit. In other words, the user may design his/her own light display output (e.g. still graphics or animations) to be displayed by the light display unit upon occurrence of the type of event.

[00053] In various embodiments, the user input may indicate a set of states having a same state for all the light emitting elements of the light display unit. For example, as shown in FIG. 5 A, the user may be presented with an“EDITOR” interface and a virtual image of a computer peripheral device, such as a virtual image 524 of the headset 200. The user may then select one of the light display units 216, 218, 224, 226 on the headset 200, and select a single colour (from for example, a colour palette 526) to be set as a state of each light emitting element 216a, 218a, 224a, 226a, 224b, 226b, 224c, 226c of the light display unit 216, 218, 224, 226. As shown in FIG. 5 A, the user may select different colours for different light display units 216, 218, 224, 226.

[00054] In various embodiments, the user input may indicate different states for adjusting different light emitting elements of the light display unit. For example, as shown in FIG. 5B, a virtual image 528 of a light display unit (which may be a light display unit from a computer peripheral device such as the headset 200 or the microphone 300) may be provided. The user may select each of the light emitting elements (e.g. light emitting element 528a) of the light display unit separately from the other light emitting elements, and select a colour (from for example, the colour palette 526) for the light emitting element. Accordingly, the user may select different colours for different light emitting elements.

[00055] In various embodiments, the user input unit of the first processor-based device may obtain user input indicating, for a type of event and for a light display unit to be changed upon occurrence of the type of event, multiple sets of states for adjusting the light emitting elements of the light display unit and a time instance for each set of states. Although not shown in the figures, the user may be allowed to design not only still graphics, but also animated graphics or light effects. For example, for each light emitting element, the user may be presented with an option to select a number of colours and a sequence of the colours for the light emitting element at consecutive time instances within a time period. Each colour selected by the user may be the colour of the light emitting element at a respective time instance within the time period. This allows the user to design an animated graphic or light effect. In various embodiments, user input indicating a time instance for each set of states may include a time interval between consecutive sets of states to be displayed at consecutive time instances. For example, in the“EDITOR” interface, the user may be presented with an option to indicate this time interval. Accordingly, the user may be able to design flashing colours by providing to the “EDITOR” interface, a number of flashes (corresponding to the number of colours selected by the user) and a time interval between the flashes.

[00056] As mentioned above, the user input indicating an adjustment to be made to each light emitting element of each light display unit to be changed may include at least one set of states for adjusting the light emitting elements of the light display unit. In various embodiments, the user input unit of the first processor-based device may obtain further user input indicating an orientation of a light display output defined by the at least one set of states for adjusting the light emitting elements of the light display unit. The light display output may be a graphic, for example, an emote and may be designed by the user or selected by the user from predetermined light display outputs. Although not shown in the figures, the user may be presented with an option to select the orientation of the light display output, where the option may allow the user to rotate the light display output by increments of a certain angle e.g. 90 degrees.

[00057] In various embodiments, the user input unit of the first processor-based device may obtain user input providing a base set of states for the light emitting elements of each light display unit. The base set of states may represent a base light display output (e.g. a base emote or a base lighting effect) to be displayed on the light display unit. Although not shown in the figures, the user may be presented with a toggle button to indicate if the base light display output should be displayed on a light display unit when it is determined that no changes are to be made to the light display unit. When this toggle button is turned off, the display on a light display unit when it is determined that no changes are to be made to the light display unit may be controlled differently (e.g. by another application).

[00058] FIG. 6 shows a flow chart of a method 600 of controlling one or more light display units during a live broadcast. In various embodiments, each light display unit may include a matrix of independently controllable light emitting elements. The method may be performed by the first processor-based device, where the first processor-based device may be operative to run on one or more broadcasting platforms (e.g. Twitch, Huya etc.) configured to perform the live broadcast. The one or more light display units may include a first subset of light display units having at least one light display unit connected to the first processor-based device of the broadcaster. For instance, the first subset of light display unit(s) may be attached to computer peripheral device(s) connected to the first processor-based device.

[00059] In the embodiment shown in FIG. 6, the method 600 may further include controlling a second subset of light display units having at least one light display unit connected to a second processor-based device (e.g. a host computer or a computing device) of a viewer. For instance, the second subset of light display unit(s) may be attached to computer peripheral device(s) connected to the second processor-based device. Each light display unit of the second subset may correspond to a light display unit of the first subset. The correspondence may be that the light display units are attached to similar computer peripheral devices. For example, a light display unit 216 of a headset 200 belonging to a viewer may correspond to a light display unit 216 of a headset 200 belonging to the broadcaster.

[00060] Referring to FIG. 6, the method 600 may include 602 to 618, where 602 to 614 may be performed by the first processor-based device of the broadcaster and 616 to 618 may be performed by the second processor-based device of the viewer. In some embodiments, the method 600 may only include controlling light display unit(s) connected to the first processor- based device of the broadcaster. In other words, 614 to 618 of the method 600 may be optional.

[00061] At 602, a data receiving unit of the first processor-based device may receive data from the one or more broadcasting platforms configured to perform the live broadcast. The data may indicate occurrence of a live event related to the live broadcast. For example, the live event may be of a type belonging to a“Follows” event.

[00062] At 604, a data comparing unit of the first processor-based device may compare the received data with stored settings. The stored settings may include settings for each type of multiple types of events, where the settings for each type of event may indicate one or more light display units to be changed upon occurrence of the type of event, and an adjustment to be made to each light emitting element of each light display unit to be changed. In some embodiments, user input may be obtained for one or more types of the multiple types of events and at least some of the settings may be configured based on the user input and stored. This user input may be obtained and stored (as settings) using the method as described with reference to FIGS. 4 and 5 A to 5B above. However, the user input maybe obtained and stored (as settings) using any other method as known to those skilled in the art. In some alternative embodiments, the settings may be configured independent of user input.

[00063] At 606, a light display controller of the first processor-based device may determine for each light display unit of the first subset (in other words, of the broadcaster), whether the light display unit is to be changed based on the comparing in 604. This may include determining the type of event to which the live event (whose occurrence is indicated by the received data) belongs, and determining whether the light display unit is one of the one or more light display units to be changed upon occurrence of the type of event to which the live event belongs. In various embodiments, determining whether each light display unit of the first subset is to be changed may be further based on the user input indicating whether to change any light display unit upon occurrence of the type of event to which the live event belongs. [00064] At 608, if the light display unit is determined as to be changed, the light display controller of the first processor-based device may determine an adjustment to be made to each light emitting element of the light display unit based on the stored settings that may be configured based on user input. For example, this may be based on the predetermined light display output selected by the user or the light display output designed by the user (e.g. using the interfaces shown in FIGS. 5A to 5B). In various embodiments, if the light display unit is determined as not to be changed, the processor-based device may (at 612) maintain the states of the light emitting elements of the light display unit or may adjust the states of the light emitting elements according to the base set of states representing a base light display output as described above.

[00065] At 610, the light display controller of the first processor-based device may adjust the light emitting elements of the light display unit based on the determined adjustments. As mentioned above, the stored settings indicating an adjustment to be made to each light emitting element of a light display unit may include at least one set of states for adjusting the light emitting elements of the light display unit. In various embodiments, adjusting the light emitting elements of the light display unit based on the determined adjustments may include simultaneously adjusting the light emitting elements of the light display unit to adopt the states in the at least one set of states provided in the settings. The simultaneous changes may allow graphics such as a“heart” graphic to be displayed.

[00066] In various embodiments, the broadcaster may send data indicating the light display output(s) displayed on light display unit(s) of his/her computer peripheral devices to the viewer, so that the same light display output(s) may also be displayed on corresponding light display unit(s) of the viewer’s computer peripheral devices.

[00067] Referring to FIG. 6, at 614, the light display controller of the first processor-based device may send adjustment data indicating the adjustments to be made to the light emitting elements of the light display units of the first subset from the first processor-based device of the broadcaster to the second processor-based device of the viewer. In various embodiments, the adjustment data may first be sent to the one or more broadcasting platforms and then sent to the second processor-based device. At 616, a data receiving unit of the second processor- based device may receive the adjustment data. At 618, a light display controller of the second processor-based device may adjust each light emitting element of each light display unit of the second subset based on the adjustment to be made to each light emitting element of a corresponding light display unit of the first subset. The adjustments at 618 may be based on the adjustment data received by the second processor-based device at 616. In various embodiments, there may be a time delay between adjusting the light emitting elements of each light display unit of the second subset and adjusting the light emitting elements of the corresponding light display unit of the first subset. For example, the light emitting elements of a light display unit of the second subset may be adjusted later than the light emitting elements of a corresponding light display unit of the first subset. Accordingly, the light display unit of the second subset may be changed later than the corresponding light display unit of the first subset. The time delay may be approximately equal to a time duration required for the broadcaster’s video stream to be transmitted from the broadcaster’s first processor-based device to the viewer’s second processor-based device. This can allow the viewer to see the changes on his/her light display units as being synchronized with the changes on the broadcaster’s light display units shown in the broadcaster’s video stream.

[00068] In various embodiments, 610 and 618 of method 600 may be performed by sending control data from the first or second processor-based device to the computer peripheral device(s) having the light display unit(s). For example, the control data may be sent to the headset receiver 228 of the headset 200 or the microphone receiver of the microphone 300.

[00069] In various embodiments, method 400 and method 600 may be at least partially performed by running an analysis application on the first processor-based device, where the analysis application may be integrated with the one or more broadcasting platforms. For example, the application program interfaces (APIs) of the analysis application may be linked with the APIs of the broadcasting platform(s). The analysis application may allow the user the ability to adjust and customize the lighting profile on the light display units in the manner as described above. The analysis application may provide the user access to various“quick effects”.

[00070] The integration of the analysis application with one or more broadcasting platforms may be done by the user by for example, having the user select a list of broadcasting platforms to be integrated with the analysis application. An option may be provided to the user to authorize one or more broadcasting platforms to communicate with the analysis application (for example, an ID may be used to access the analysis application and the ID may be supplied to the broadcasting platforms as well). In some embodiments, 602 to 608 of the method 600 may be performed using the analysis application which can be integrated with one or more broadcasting platforms, whereas 610, 612 may be performed using a control application (which may be referred to as“Chroma SDK” application) which may interact with the analysis application. Various computer peripheral devices may be compatible, or in other words, capable of communicating with the first processor-based device through the control application. For example, the headset receiver 228 of the headset 200 and the microphone receiver of the microphone 300 may be configured to receive data from the control application running on the first processor-based device.

[00071 ] FIG. 7 shows an example of how an analysis application 706 may be integrated with other applications 704, 708, where the application 704 may be a broadcasting platform and the application 708 may be a control application. During a live broadcast, the broadcasting platform 704 may be configured to receive data from various sources 702 such as different viewers, where the data may indicate occurrence of different live actions such as“Follow” actions (and thus, the occurrence of various live events related to the live broadcast). The broadcasting platform 704 may then send this data to the analysis application 706 which may determine how the light display units 710 should be changed using for example, 602 - 608, 612 of method 600. The analysis application 706 may then send data indicating how the light display units 710 should be changed to the control application 708 which may then send control data to the computer peripheral devices having the light display units 710.

[00072] In various embodiments, the above-mentioned analysis application and/or control application may be configured to send the adjustment data (indicating the adjustments to be made to the light emitting elements of the light display units of the broadcaster) from the broadcaster’s first processor-based device to the viewer’s second processor-based device through an extension API of the broadcasting platform, such as, but not limited to, the extension API of Twitch. This may be done by the broadcaster installing an extension (e.g. Chroma extension) through extension tabs of the broadcasting platform (e.g. Twitch extension tabs) configured to be run on the first processor-based device. In various embodiments, when the broadcaster sends the adjustment data as determined based on the stored settings in the first processor-based device, the broadcaster may be prevented from also sending other data indicating the adjustments to be made to the light emitting elements of the light display unit(s) triggered by other applications or platforms

[00073] In various embodiments, the analysis application may be further integrated with a further application, such as a game application, configured to run on the first processor-based device. The further application may provide light display output(s) for the light display unit(s) of the broadcaster. Data indicating such light display output(s) may be sent from the further application to the analysis application which may then use this data to determine the adjustments to be made to the light emitting elements of the light display unit(s). In some embodiments, the adjustment data sent from the first to the second processor-based device may also include the aforementioned data from the further application. [00074] In various embodiments, the categories of events may differ from the categories mentioned above. In various embodiments, further categories as known to those skilled in the art, such as, but not limited to, a“Donate” category may be included. Different types of “Donate” events in the“Donate” category may be defined based on different conditions related to“donation” actions e.g. number of“donation” actions, amounts donated in the“donation” actions. The donations in these“donation” actions may be in different currencies. Information of the “donation” actions may be derived from donation platforms that may also run simultaneously with the analysis applications (and in some embodiments, the control applications) on the first processor-based device. In various embodiments, the APIs of donation platforms may be linked to the APIs of the broadcasting platforms and the user may be able to select if he/she wishes for“Donate” events to trigger actions on the broadcasting platforms. For example, instead of or further to having the broadcasting platforms handle the “Follower” actions, the donation platforms may handle the“Follower” actions, such that a “Follower” action is triggered in response to a“Donate” action. Accordingly, lighting effects may be synced to an overlay function that the user may be using through the donation platforms.

[00075] The live broadcast may include multiple consecutive live events. In various embodiments, the determined adjustments for each light display unit upon occurrence of a first live event may include a first group of adjustments and the light display controller of the first processor-based device may form a queue for each light display unit, where the queue may include the first group of adjustments. The light display controller of the first processor-based device may then repeatedly perform the following: receive further data from the one or more broadcasting platforms, where the further data may indicate occurrence of a next live event related to the live broadcast; compare the received further data with the stored settings; and for each light display unit, determine whether the light display unit is to be changed based on the comparing of the received further data with the stored settings, if the light display unit is determined as to be changed, determine a next group of adjustments to be made to the light emitting elements of the light display unit based on the stored settings, and adjust the queue for the light display unit by adding the next group of adjustments after a previous group of adjustments. Accordingly, a queue for each light display unit indicating consecutive changes to be made to the light display unit may be formed. The light emitting elements of each light display unit may then be adjusted to adopt the groups of adjustments in the queue in sequential order (in other words, in the order of the groups of adjustments indicated in the queue). [00076] Occasionally, the frequency of live events in a live broadcast may be high and the time period (e.g. about 5 - 10 seconds) to display each light display output may be longer than the time period between consecutive live events. This may result in a long queue being formed and hence, the light emitting elements of the light display unit(s) may adopt a group of adjustments long after the live event that triggered the group of adjustments. In various embodiments, the user input unit of the first processor-based device may further receive user input indicating to clear the queue for a light display unit of the first subset and the light display controller of the first processor-based device may adjust the queue for the light display unit by removing all groups of adjustments from the queue. For instance, the broadcaster may be presented with a virtual button which may be activated to clear the queue. When the virtual button is activated, the broadcaster may still receive notifications of further live events, but the light emitting elements of the light display unit(s) of the broadcaster may not be adjusted in response to some of the further live events.

[00077] In various embodiments, one or both of the first and second processor-based devices may receive user input indicating whether to display one or more characteristics of each type of live event. This display may be after the light emitting elements of the light display unit(s) are adjusted upon occurrence of the type of live event (e.g. after 610 or 618 of method 600). The characteristics of a type of live event may include a user name of the individual triggering the event, a time of the event or any other characteristic as known to those skilled in the art. For example, the user name of the individual triggering a live event may be displayed after an emote is displayed on a light display unit. In various embodiments, a toggle button may be presented to the broadcaster to indicate whether to display the one or more characteristics of each type of live event. In some embodiments, the toggle button may be deactivated by default. In various embodiments, the user input unit of the first processor-based device may further receive user input indicating how to display the one or more characteristics of each type of live event. For example, the broadcaster may be able to select whether text showing the characteristic of a type of live event scrolls left to right or right to left.

[00078] In various embodiments, the user input unit(s) of one or both of the first and second processor-based devices may receive user input indicating a display time period for which a light display output is to be displayed on a light display unit. In other words, the display time period represents a time period for which the light emitting elements of a light display unit should adopt a set of states (provided in a light display output). Adjusting the light emitting elements of the light display unit may then include configuring the light emitting elements of the light display unit to adopt the set of states for the display time period. The display time period may range from 5 to 10 seconds and may be set by the broadcasters to align with onscreen notifications from the broadcasting platforms or other applications. In various embodiments, a drop down box may be provided for the broadcaster to indicate the display time period. The drop down box may include values ranging from 1 to 999. In various embodiments, the analysis application may employ other drop down boxes which may also include values ranging from 1 to 999.

The computer-readable medium/memory 814 may also be used for storing data that is manipulated by the processor 806 when executing software. For example, the computer- readable medium/memory 814 may be used for storing the user input obtained using the method 400 as described with reference to FIG. 4. The first processor-based device 802 may further include the components 808, 810, 812, 813 that maybe used for executing the methods 400, 600 as described with reference to FIGS. 4 to 6.
