BACKGROUND

[oooi] Users have access to a wide range of computing devices, such as desktop PCs, mobile computing devices (e.g., tablets, smart phones), laptops, game consoles, and so on. Further, a wide variety of peripheral devices may be configured to expand the functionality that is available from the computing devices.

[0002] Conventional techniques are available such that the peripheral device may be configured to communicate with the computing device to operate for an intended function, such as to act as a storage device. However, these conventional techniques are generally limited to support of communication between the devices and therefore do not support other functionality.

SUMMARY

[0003] User experience adaptation techniques are described. In one or more implementations, an apparatus includes a connection portion configured to be removably physically and communicatively with a computing device, a housing physically connected to the connection portion and providing an outer surface having one or more characteristics that are viewable by a user, and memory disposed within the housing and configured to communicate data to the computing device via the connection portion, the data usable by the computing device to dynamically adapt a user interface displayable by a display device of the computing device to mimic the one or more physical characteristics of the housing.

[0004] In one or more implementations, data is received at a computing device from a peripheral device that is removably communicatively and physically attachable to the computing device. The data is used to alter a user experience implemented in software of the computing device.

[0005] In one or more implementations, a device includes a connection portion having one or more magnets configured to form a physical coupling with a computing device and a portion that is secured to the connection portion using a flexible hinge that is configured to permit rotational movement of the portion with respect to the computing device when physically coupled to the computing device using the one or more magnets. The portion contains memory having data that is configured to be communicated through the connection portion to the computing device to cause the computing device to configure a display to mimic one or more visual characteristics of the device.

DETAILED DESCRIPTION

Overview

[0016] Users have access to a wide range of peripheral devices that may be utilized to expand the functionality of a computing device. This may include protecting a computing device (e.g., a cover), acting as an input device (e.g., a keyboard, mouse, track pad), supporting use for data storage (e.g., a thumb drive), configuration as an output device (e.g., headphones), and so on.

[0017] These peripheral devices may be designed to have physical characteristics to aid a user's experience with the device. This may include a particular "look and feel" (e.g., a metallic housing with rounded corners), may include different versions of the device (e.g., headphones having different colors), and so on. Thus, physical characteristics of a peripheral device that is selected for use in conjunction with a computing device may be indicative of a user's preferences regarding interaction with the computing device.

[0018] Accordingly, techniques are described herein that may leverage this indication to further improve a user's experience with a computing device. A user, for instance, may select a cover for a tablet computer in a particular color. The cover may be configured to communicate data that describes this color to the computing device. The computing device may then use this data to alter a user's experience with the computing device. This may include changing sounds, mimicking physical characteristics of the device (e.g., color, texture, shape of a housing), and so on. Thus, a unified user experience may be supported by the peripheral device and the computing device.

[0019] For example, a user may communicatively couple (e.g., wired or wirelessly) a mouse having a particular color to a computing device. Data may be communicated from the mouse that describes this color such that the computing device may adapt accordingly, e.g., change a background to match the color, to a complimentary color, and so on. In this way, characteristics of the mouse may be seamlessly integrated as part of a user experience of the computing device automatically and without user intervention. Further discussion of these and other examples may be found in relation to the following sections.

[0020] In the following discussion, an example environment and example adaptations are first described that may employ the techniques described herein. Example procedures are then described which may be performed in the example environment as well as other environments. Consequently, performance of the example procedures is not limited to the example environment and the example environment is not limited to performance of the example procedures.

Example Environment

[0021] FIG. 1 is an illustration of an environment 100 in an example implementation that is operable to employ the techniques described herein. The illustrated environment 100 includes an example of acomputing device 102 that is physically and communicatively coupled to a device 104 via a flexible hinge 106. The computing device 102 may be configured in a variety of ways. For example, the computing device 102 may be configured for mobile use, such as a mobile phone, a tablet computer as illustrated, and so on. Thus, the computing device 102 may range from full resource devices with substantial memory and processor resources to a low-resource device with limited memory and/or processing resources as further described in relation to FIG. 8. The computing device 102 may also relate to software that causes the computing device 102 to perform one or more operations. Although the device 104 is illustrated as an input device, the device 104 may be configured in a variety of ways, further discussion of which may be found in relation to FIG. 4. [0022] The computing device 102 is illustrated as including an input/output module 108. The input/output module 108 is representative of functionality relating to processing of inputs and rendering outputs of the computing device 102. A variety of different inputs may be processed by the input/output module 108, such as inputs relating to functions that correspond to keys of the device 104, keys of a virtual keyboard displayed by the display device 110 to identify gestures and cause operations to be performed that correspond to the gestures that may be recognized through the device 104 and/or touch screen functionality of the display device 110, and so forth. Thus, the input/output module 108 may support a variety of different input techniques by recognizing and leveraging a division between types of inputs including key presses, gestures, and so on.

[0023] In the illustrated example, the device 104 is configured as a keyboard having a QWERTY arrangement of keys although other arrangements of keys are also contemplated as well as other arrangements of the device 104 that is not configured as an input device. For example, other non-conventional configurations are also contemplated, such as a game controller, configuration to mimic a musical instrument, a cover, a storage device, an output device (e.g., headphones), and so forth. Thus, the device 104 may assume a variety of different configurations to support a variety of different functionality for use in conjunction with the computing device 102.

[0024] As previously described, the device 104 is physically and communicatively coupled to the computing device 102 in this example through use of a flexible hinge 106. The flexible hinge 106 is flexible in that rotational movement supported by the hinge is achieved through flexing (e.g., bending) of the material forming the hinge as opposed to mechanical rotation as supported by a pin, although that embodiment is also contemplated. Further, this flexible rotation may be configured to support movement in one direction (e.g., vertically in the figure) yet restrict movement in other directions, such as lateral movement of the device 104 in relation to the computing device 102. This may be used to support consistent alignment of the device 104 in relation to the computing device 102, such as to align sensors used to change power states, application states, and so on. [0025] The flexible hinge 106, for instance, may be formed using one or more layers of fabric and include conductors formed as flexible traces to communicatively couple the device 104 to the computing device 102 and vice versa. This communication, for instance, may be used to communicate a result of a key press to the computing device 102, receive power from the computing device, perform authentication, provide supplemental power to the computing device 102, and so on. The communication may also be used to communicate data that may be used to alter a user experience of the computing device 102 based on physical characteristics of the device 104 as further described beginning in relation to FIG. 4. The flexible hinge 106 may be configured in a variety of ways, further discussion of which may be found in relation to the following figure.

[0026] FIG. 2 depicts an example implementation 200 of the device 104 of FIG. 1 as showing the flexible hinge 106 in greater detail. In this example, a connection portion 202 of the input device is shown that is configured to provide a communicative and physical connection between the device 104 and the computing device 102. In this example, the connection portion 202 has a height and cross section configured to be received in a channel in the housing of the computing device 102, although this arrangement may also be reversed without departing from the spirit and scope thereof.

[0027] The connection portion 202 is flexibly connected to a portion of the device 104 that includes the keys through use of the flexible hinge 106. Thus, when the connection portion 202 is physically connected to the computing device the combination of the connection portion 202 and the flexible hinge 106 supports movement of the device 104 in relation to the computing device 102 that is similar to a hinge of a book.

[0028] For example, rotational movement may be supported by the flexible hinge 106 such that the device 104 may be placed against the display device 110 of the computing device 102 and thereby acting as a cover. The device 104 may also be rotated so as to be disposed against a back of the computing device 102, e.g., against a rear housing of the computing device 102 that is disposed opposite the display device 110 on the computing device 102. [0029] Naturally, a variety of other orientations are also supported. For instance, the computing device 102 and device 104 may assume an arrangement such that both are laid flat against a surface as shown in FIG. 1. In another instance, a typing arrangement may be supported in which the device 104 is laid flat against a surface and the computing device 102 is disposed at an angle to permit viewing of the display device 110, e.g., such as through use of a kickstand disposed on a rear surface of the computing device 102. Other instances are also contemplated, such as a tripod arrangement, meeting arrangement, presentation arrangement, and so forth.

[0030] The connecting portion 202 is illustrated in this example as including magnetic coupling devices 204, 206, mechanical coupling protrusions 208, 210, and a plurality of communication contacts 212. The magnetic coupling devices 204, 206 are configured to magnetically couple to complementary magnetic coupling devices of the computing device 102 through use of one or more magnets. In this way, the device 104 may be physically secured to the computing device 102 through use of magnetic attraction.

[0031] The connecting portion 202 also includes mechanical coupling protrusions 208, 210 to form a mechanical physical connection between the device 104 and the computing device 102. The mechanical coupling protrusions 208, 210 are shown in greater detail in the following figure.

[0032] FIG. 3 depicts an example implementation 300 shown a perspective view of the connecting portion 202 of FIG. 2 that includes the mechanical coupling protrusions 208, 210 and the plurality of communication contacts 212. As illustrated, the mechanical coupling protrusions 208, 210 are configured to extend away from a surface of the connecting portion 202, which in this case is perpendicular although other angles are also contemplated.

[0033] The mechanical coupling protrusions 208, 210 are configured to be received within complimentary cavities within the channel of the computing device 102. When so received, the mechanical coupling protrusions 208, 210 promote a mechanical binding between the devices when forces are applied that are not aligned with an axis that is defined as correspond to the height of the protrusions and the depth of the cavity.

[0034] For example, when a force is applied that does coincide with the longitudinal axis described previously that follows the height of the protrusions and the depth of the cavities, a user overcomes the force applied by the magnets solely to separate the device 104 from the computing device 102. However, at other angles the mechanical coupling protrusion 208, 210 are configured to mechanically bind within the cavities, thereby creating a force to resist removal of the device 104 from the computing device 102 in addition to the magnetic force of the magnetic coupling devices 204, 206. In this way, the mechanical coupling protrusions 208, 210 may bias the removal of the device 104 from the computing device 102 to mimic tearing a page from a book and restrict other attempts to separate the devices.

[0035] The connecting portion 202 is also illustrated as including a plurality of communication contacts 212. The plurality of communication contacts 212 is configured to contact corresponding communication contacts of the computing device 102 to form a communicative coupling between the devices. The communication contacts 212 may be configured in a variety of ways, such as through formation using a plurality of spring loaded pins that are configured to provide a consistent communication contact between the device 104 and the computing device 102. Therefore, the communication contact may be configured to remain during minor movement of jostling of the devices. A variety of other examples are also contemplated, including placement of the pins on the computing device 102 and contacts on the device 104.

Example Adaptations

[0036] FIG. 4 depicts an example implementation 400 in which a user experience of a computing device 102 is adapted based on one or more physical characteristics of the device 104. As shown in FIG. 1, a start screen of an operating system of the computing device is displayed that includes a plurality of tiles. The tiles may be utilized to output information (e.g., weather, notifications, and so on) as well as configured to be selectable to launch a corresponding application. In the illustrated example of FIG. 1, the start screen is a default configuration that is not altered.

[0037] However, in the example implementation 400 of FIG. 4, the start screen displayed by the display device 110 is altered based on one or more physical characteristics of the device 104. The device 104, for instance, may include data 402 that is stored in memory of the device 104 (e.g., flash memory or other computer-readable storage media) and configured to be communicated to the computing device 102. The data 402 may be communicated in a variety of ways, such as a wired or wireless connection.

[0038] The data 402 may be configured to describe physical characteristics of the device 104. This may be performed indirectly, such as to identify the device 104 itself (e.g., model number), or directly, such as to identify the physical characteristics of the device 104. For example, an HID descriptor table may be configured to describe the characteristics of the device 104. Further, this data 402 may be configured to be sufficient by itself for adapting the user experience or may be leveraged with other data, such as through configuration of a link to a network service to obtain the additional data, such as how to alter the user experience.

[0039] The input/output module 108 of the computing device 102 may then configure a user experience based on this data 402, thereby providing a consistent user experience that is supported by a "look and feel" of the device 104 as well as a user interface of the computing device 102.

[0040] The device 104, for instance, may expose the data 402 to the computing device 102. The computing device 102 may then dynamically and automatically adapt a user experience based on a user's preference as exhibited by their choice of physical appearance of the device 104. A user, for instance, may decide purchase a blue electronic accessory peripheral, as blue is the user's favorite color. The device 104, for instance, may have a housing (e.g., a flexible surface for a pressure sensitive keyboard in this example) that is blue in color. This device 104 may be selected from a plurality of similar versions (e.g., different colors) of the device from a same or different manufacturer and thus exhibits a preference of a user in making the selection. [0041] Thus, once the device 104 is communicatively coupled to the computing device 102 (e.g., wired or wireless), software of the computing device 102 may be used to dynamically adapt the user experience by the input/output module 108. This adaptation may be performed to match the user's preference previously exhibited by the physical characteristics of the device 104 as indicated by the data 402. For example, a background displayed by the display device 110 may be configured to mimic the outer surface of the device 104, such as to have a color, appear to have a texture, and so on as described in the previous instance.

[0042] The adaptation may also include graphics that are the same as or complementary to the physical characteristics of the device 104. In the illustrated example, for instance, the device 104 includes a housing that is consistent with an outdoor theme and thus includes leaves, mountains, trees, and so on. The computing device 110, through receipt of the data 402, may also configure a display of the display device 1 10 to be consistent with this theme, which may include colors, graphics (e.g., trees), touch and feel (e.g., hard, soft, rigid, flexible), and so on. Although a display is shown, other aspects of a user experience may also be altered, e.g., sounds output by the computing device 102 responsive to a keystroke, notification, selection, volume, intensity, and so on. This may be used to support a variety of different functionality and may be performed using a variety of different techniques.

[0043] For example, upon enumeration or presence detection of the device 104 by the computing device 102, an operating system, application, or other functionality of the computing device 102 may obtain the data from the device 104, such as responsive to query of the device 104. This query may be performed to locate physical characteristics of the device 104 as previously described. Examples of adaptations that may be performed based on the physical characteristics include color, graphic overlay, visual patterns, a business or organizational brand, theme, logo, name, text, application windows, menus, titles, icons, names, animations, text colors, font size, background or highlight colors, and so on. Other physical characteristics may also be conveyed by the data 402, such as size, shape (e.g., rounded, sharp), texture, and so forth and may also be used as a basis to adapt the user experience. For instance, rounded corners of the device 104 may be used to configure the tiles in the user interface to have rounded corners as well as displayed using a color that is complementary to a color of the device 104.

[0044] Thus, this data 402 may be used by the input/output module 108 to adapt a user experience to be consistent to the user's preference dictated by their selection and purchase of the hardware accessory and its characteristics. Thus, the proximity of the device 104 and the computing device 102 may be used to support an improved user experience through consistency of these parts. As shown in the example implementation 400 of FIG. 4, for instance, an outdoor theme of the device 104 may "carry over" to a user interface displayed by the display device 110. A variety of other examples are also contemplated, one of which is described as follows.

[0045] FIG. 5 depicts another example implementation 500 in which a user experience of a computing device 102 is adapted based on one or more physical characteristics of the device 104. In this example, the device 104 is configured according to an underwater theme and thus appears similar to an aquarium. Supporting this are graphics included on a housing of the device 104 that include an appearance of sand, water, seahorses, and fish.

[0046] The user interface displayed by the display device 110 is also configured to continue this theme. This includes a background that appears as water along with animations of fish swimming behind and in front of the tiles of the start menu. The user interface is also configured to finish a portion of a graphic of the device 104, which in this instance is a fish in which a tail is viewable on the housing of the device 104 and a head of the fish is displayed by the display device 110. In this way, the user interface displayed by the display device 110 may appear as a continuation of visual physical characteristics of the device 104.

[0047] FIG. 6 depicts yet another example implementation 600 in which a user experience of a computing device 102 is adapted based on one or more physical characteristics of the device 104. A business entity or organization may incorporate elements of a brand, logo, colors, theme, slogan, names or text through an independent hardware vendor implementation of the device 104. Thus, in this example the data 402 may provide a representation of the user's selection of that organization or entity and corresponding elements through a user experience that is adapted by the computing device 102 (e.g., operating system or other software) based on that selection. Therefore, the data 402 may support techniques for a hardware manufacturer or technology provider to incorporate physical characteristics, such as color, shape, theme, logo, slogan, text or other branding elements (representing an organizational, company or other entity), advertisements, names or other visual patterns complimentary to the background color. This may be used to convey a meaning, purpose or association to the end user between the device and the computing device that may be automatically performed without user intervention.

[0048] In the illustrated example implementation 600, the device 104 is configured to include game controller functionality. Although this functionality is arranged above a keyboard in the illustrated example, stand-alone implementations are also contemplated. The device 104 also includes colors and graphics relating to a particular video game, which is "Halo 4" in this example.

[0049] Data 402 from the device 104 may then be leveraged by the computing device 102 to adapt the user experience accordingly. A user interface displayed by the display device 1 10, for instance, may include a background image taken directly from the data 402 and/or located using the data 402. Tiles of the user interface may also be displayed in a color that is complementary to a color of the housing of the input device 104, e.g., a fabric covering of a pressure-sensitive keyboard. Sounds may also be adapted, such as to use sounds from the video game for notifications, reminders, key presses, launching of applications, and so forth.

[0050] A variety of other examples are also contemplated without departing from the spirit and scope thereof, such as to support updates that may be used to adapt the user experience over time, thereby promoting a "fresh" user experience with a combination of the computing device 102 and device. For instance, applications and tools of the computing device 102 may be paired with the device 104 to make them more readily accessible, such as through inclusion of the "Halo 4" tile in the illustrated example and switch of the user interface to show "games." [0051] In another instance, the device 104 may contain information in the data 402 that is sufficient to automatically pull down applications from an application store, such as through use of an application ID to obtain a trial version of an application responsive to attachment of the device 104. In a further instance, location based adaptation may be supported. The computing device 102, for instance, may include location determination functionality (e.g., GPS, wireless network) such that the user interface may be adapted based on where the computing device 102 is located, e.g., a sporting event, store, and so on. Further, although these techniques are described in which the computing device 102 is changed based on the device 104, the reverse may also be supported in which a user experience of the device 104 is changed based on the computing device 102, display settings, themes, and so forth.

Example Procedure

[0052] The following discussion describes user experience adaptation techniques that may be implemented utilizing the previously described systems and devices. Aspects of each of the procedures may be implemented in hardware, firmware, or software, or a combination thereof. The procedures are shown as a set of blocks that specify operations performed by one or more devices and are not necessarily limited to the orders shown for performing the operations by the respective blocks. In portions of the following discussion, reference will be made to the environment 100 and example implementations 200-600 of FIGS. 1-6.

[0053] FIG. 7 depicts a procedure 700 in an example implementation in which a user experience is adapted based at data that is received from a peripheral device. Data is received at a computing device from a peripheral device that is removably communicatively and physical attachable to the computing device (block 702). The peripheral device may assume a variety of configurations and provide a variety of functionality for use by the computing device 102. This may include use to protect the computing device 102 (e.g., as a cover), an input device (e.g., game controller, keyboard), storage device (e.g., thumb drive), output device (e.g., headphones), and so on. The data may be received in a variety of ways, both wired and wirelessly, and be configured in a variety of ways. For example, the data may be configured as a link to a network service, may provide an ID of a device, identify physical characteristics of the device, may be usable to obtain data "over the cloud," and so forth.

[0054] The data is used to adapt of user experience implemented in software of the computing device (block 704). This may include altering a user interface to mimic physical characteristics of the device 104 without displaying a representation of the device. For example, a menu may be provided when a peripheral device is attached to a computing device 102 that shows the device, such as to configure options of the device. In this instance, however, other functionality of the computing device 102 that is not directly related to the device, otherwise, may be adapted, such as backgrounds, colors, sounds, and so forth as previously described. In one or more implementations, an option may be output that is selectable by a user to verify whether the user wishes to have the adaptation performed.

[0055] An indication is received that the peripheral device has been disconnected from the computing device (block 706). Responsive to the receipt of the indication, the adaptation of the user experience caused by the data is removed (block 708). For example, the computing device 102 may support interchangeability of a variety of different devices. Accordingly, the computing device 102 may be configured to adapt the user experience based on which device is currently communicatively coupled to the computing device 102. In an instance in which multiple devices support this functionality, the computing device 102 may be configured to prioritize adaptations, adapt different parts of the user interface (e.g., for an adaptation to a part of the user experience that is supported by one device but not both), and so forth. Other instances are also contemplated, such as to have the adaptations remain after disconnection of the device, remain until new adaptations are available from another device, and so on.

Example System and Device

[0056] FIG. 8 illustrates an example system generally at 800 that includes an example computing device 802 that is representative of one or more computing systems and/or devices that may implement the various techniques described herein. The computing device 802 may be, for example, be configured to assume a mobile configuration through use of a housing formed and size to be grasped and carried by one or more hands of a user, illustrated examples of which include a mobile phone, mobile game and music device, and tablet computer although other examples are also contemplated such as desktop computers, laptops, and so forth.

[0057] The example computing device 802 as illustrated includes a processing system 804, one or more computer-readable media 806, and one or more I/O interface 808 that are communicatively coupled, one to another. Although not shown, the computing device 802 may further include a system bus or other data and command transfer system that couples the various components, one to another. A system bus can include any one or combination of different bus structures, such as a memory bus or memory controller, a peripheral bus, a universal serial bus, and/or a processor or local bus that utilizes any of a variety of bus architectures. A variety of other examples are also contemplated, such as control and data lines.

[0058] The processing system 804 is representative of functionality to perform one or more operations using hardware. Accordingly, the processing system 804 is illustrated as including hardware element 810 that may be configured as processors, functional blocks, and so forth. This may include implementation in hardware as an application specific integrated circuit or other logic device formed using one or more semiconductors. The hardware elements 810 are not limited by the materials from which they are formed or the processing mechanisms employed therein. For example, processors may be comprised of semiconductor(s) and/or transistors (e.g., electronic integrated circuits (ICs)). In such a context, processor-executable instructions may be electronically-executable instructions.

[0059] The computer-readable storage media 806 is illustrated as including memory/storage 812. The memory/storage 812 represents memory/storage capacity associated with one or more computer-readable media. The memory/storage component 812 may include volatile media (such as random access memory (RAM)) and/or nonvolatile media (such as read only memory (ROM), Flash memory, optical disks, magnetic disks, and so forth). The memory/storage component 812 may include fixed media (e.g., RAM, ROM, a fixed hard drive, and so on) as well as removable media (e.g., Flash memory, a removable hard drive, an optical disc, and so forth). The computer-readable media 806 may be configured in a variety of other ways as further described below.

[0060] Input/output interface(s) 808 are representative of functionality to allow a user to enter commands and information to computing device 802, and also allow information to be presented to the user and/or other components or devices using various input/output devices. Examples of input devices include a keyboard, a cursor control device (e.g., a mouse), a microphone, a scanner, touch functionality (e.g., capacitive or other sensors that are configured to detect physical touch),a camera (e.g., which may employ visible or non-visible wavelengths such as infrared frequencies to recognize movement as gestures that do not involve touch), and so forth. Examples of output devices include a display device (e.g., a monitor or projector), speakers, a printer, a network card, tactile-response device, and so forth. Thus, the computing device 802 may be configured in a variety of ways to support user interaction.

[0061] The computing device 802 is further illustrated as being communicatively and physically coupled to an input device 814 that is physically and communicatively removable from the computing device 802. In this way, a variety of different input devices may be coupled to the computing device 802 having a wide variety of configurations to support a wide variety of functionality. In this example, the input device 814 includes one or more keys 816, which may be configured as pressure sensitive keys, mechanically switched keys, and so forth.

[0062] The input device 814 is further illustrated as include one or more modules 818 that may be configured to support a variety of functionality. The one or more modules 818, for instance, may be configured to process analog and/or digital signals received from the keys 816 to determine whether a keystroke was intended, determine whether an input is indicative of resting pressure, support authentication of the input device 814 for operation with the computing device 802, and so on.

[0063] Various techniques may be described herein in the general context of software, hardware elements, or program modules. Generally, such modules include routines, programs, objects, elements, components, data structures, and so forth that perform particular tasks or implement particular abstract data types. The terms "module," "functionality," and "component" as used herein generally represent software, firmware, hardware, or a combination thereof. The features of the techniques described herein are platform-independent, meaning that the techniques may be implemented on a variety of commercial computing platforms having a variety of processors.

[0064] An implementation of the described modules and techniques may be stored on or transmitted across some form of computer-readable media. The computer- readable media may include a variety of media that may be accessed by the computing device 802. By way of example, and not limitation, computer-readable media may include "computer-readable storage media" and "computer-readable signal media."

[0065] "Computer-readable storage media" may refer to media and/or devices that enable persistent and/or non-transitory storage of information in contrast to mere signal transmission, carrier waves, or signals per se. Thus, computer-readable storage media refers to non-signal bearing media. The computer-readable storage media includes hardware such as volatile and non-volatile, removable and nonremovable media and/or storage devices implemented in a method or technology suitable for storage of information such as computer readable instructions, data structures, program modules, logic elements/circuits, or other data. Examples of computer-readable storage media may include, but are not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile disks (DVD) or other optical storage, hard disks, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or other storage device, tangible media, or article of manufacture suitable to store the desired information and which may be accessed by a computer.

[0066] "Computer-readable signal media" may refer to a signal-bearing medium that is configured to transmit instructions to the hardware of the computing device 802, such as via a network. Signal media typically may embody computer readable instructions, data structures, program modules, or other data in a modulated data signal, such as carrier waves, data signals, or other transport mechanism. Signal media also include any information delivery media. The term "modulated data signal" means a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal. By way of example, and not limitation, communication media include wired media such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared, and other wireless media.

[0067] As previously described, hardware elements 810 and computer-readable media 806 are representative of modules, programmable device logic and/or fixed device logic implemented in a hardware form that may be employed in some embodiments to implement at least some aspects of the techniques described herein, such as to perform one or more instructions. Hardware may include components of an integrated circuit or on-chip system, an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), a complex programmable logic device (CPLD), and other implementations in silicon or other hardware. In this context, hardware may operate as a processing device that performs program tasks defined by instructions and/or logic embodied by the hardware as well as a hardware utilized to store instructions for execution, e.g., the computer-readable storage media described previously.

[0068] Combinations of the foregoing may also be employed to implement various techniques described herein. Accordingly, software, hardware, or executable modules may be implemented as one or more instructions and/or logic embodied on some form of computer-readable storage media and/or by one or more hardware elements 810. The computing device 802 may be configured to implement particular instructions and/or functions corresponding to the software and/or hardware modules. Accordingly, implementation of a module that is executable by the computing device 802 as software may be achieved at least partially in hardware, e.g., through use of computer-readable storage media and/or hardware elements 810 of the processing system 804. The instructions and/or functions may be executable/operable by one or more articles of manufacture (for example, one or more computing devices 802 and/or processing systems 804) to implement techniques, modules, and examples described herein.
