AND RELATED SYSTEMS AND METHODS

FIELD

[0001] The present invention relates to portable electronic devices, and, more particularly, to wireless devices used for hands free operation of portable electronic devices and associated systems and methods.

BACKGROUND

[0002] Portable electronic devices, such as mobile terminals, are commonplace in today's society. People use portable devices everywhere, such as their homes, offices, cars and the like. Many users use the portable electronic device in combination with a wireless headset, which allows the user to talk hands free. This may desirable, for example, when the device is being used in a vehicle so that both hands can remain on the steering wheel. One wireless headset is a Bluetooth headset. Bluetooth technology was designed originally for a much wider application, it has today become largely for voice transmission. Conventional portable electronic devices typically include a Bluetooth transmitter, therefore, the portable electronic device can communicate with a Bluetooth headset.

[0003] Bluetooth headsets come in many different styles. For example, standard Bluetooth headsets, such as the headsets 100 and 100' illustrated in Figures 1 A and IB, are often a single-side monaural earpiece, which can access the Headset/handsfree profile of Bluetooth. Depending on the operating system of the portable electronic device this type of headset will either play music at a very low quality because the portable electronic device is converting it into a voice signal or will be unable to play music at all because the portable electronic device cannot perform such a conversion. Users who would like a stereo-music playing Bluetooth headset, such as the headset 200 illustrated in Figure 2, should look for a headset with the A2DP profile. Users should note that some A2DP-equipped headsets will automatically de-activate the microphone function during music-listening, so if these headsets are paired to a computer via a Bluetooth connection, the headset may either disable the stereo function or the microphone function.

It will be understood that the wireless transceiver 350 and the transceiver 312 may be combined without departing from the scope of the present invention. The processor 390 can be any commercially available or custom microprocessor.

[0037] As illustrated in Figure 3, the portable electronic device communicates with a base station transceiver360 connected to a mobile switching center ("MSC") 370 in accordance with some embodiments of the present invention. The transceiver 312 typically includes a transmitter circuit and a receiver circuit, which respectively transmit outgoing radio frequency signals to the base station transceiver 360 and receive incoming radio frequency signals, such as voice and data signals, from the base station transceiver 260 via an antenna 205. The antenna 305 may be an embedded antenna, a retractable antenna or any antenna known to those having skill in the art without departing from the scope of the present invention. The radio frequency signals transmitted between the portable electronic device 340 and the base station transceiver 360 may include both traffic and control signals (e.g. , paging signals/messages for incoming calls), which are used to establish and maintain communication with another party or destination. The processor 390 may support various functions of the portable electronic device, including a wireless transceiver configured to communicate with the wireless device/headset 395 according to some embodiments of the present invention as will be discussed further herein.

[0038] It will be understood that in some embodiments of the present invention, the transceiver 312 may be a short range transceiver. The short range transceiver may be, for example, a Bluetooth transceiver, which may allow for high transfer rates of data over relatively short distances. It will be further understood that portable electronic devices 340 according to some embodiments of the present invention may include a wireless transceiver and a short range transceiver/transmitter as discussed above.

[0039] In some embodiments of the present invention, the base station transceiver 360 comprises the radio transceiver(s) that defines an individual cell in a cellular network and communicates with the portable electronic device 340 and other portable electronic devices in the cell using a radio-link protocol. Although only a single base station transceiver 360 is shown, it will be understood that many base station transceivers may be connected through, for example, a mobile switching center 370 and other devices to define a wireless

communications network.

[0040] Although the present invention may be embodied in communication devices or systems, such as the portable electronic device 340, the present invention is not limited to such devices and/or systems. Instead, the present invention may be embodied in any apparatus that may be configured to download, install, execute and/or uninstall applications from a server in accordance with embodiments of the present invention.

[00 1] Wireless devices 395 in accordance with embodiments of the present invention are configured to communicate with a portable electronic device, for example, portable electronic device 340. In some embodiments of the present invention, the wireless device 395 is a wireless headset, for example, a Bluetooth headset, that allows hands free operation of the portable electronic device 340.

[0042] As illustrated in Figure 3, a system for hands free operation of a portable electronic device in accordance with some embodiments of the present invention may include a portable electronic device 340 including a wireless transceiver 312/350 and a wireless device 395 configured to wirelessly communicate with the wireless transceiver 312/350 of the portable electronic device 340. As will be discussed below with respect to Figures 4 through 8D, wireless devices in accordance with some embodiments of the present invention include a housing and a speaker attached to the housing. The speaker is configured to be received by an ear of a user of the wireless device. Movement of the housing and/or speaker of the wireless device causes a change in functionality of the wireless device and/or the portable electronic device.

[0043] Various aspects of the wireless device/headset 395 in accordance with some embodiments of the present invention will now be discussed with respect to Figures 4 through 8D. As discussed above, conventional wireless headsets typically have very small buttons that may be hard to use. Accordingly, some embodiments of the present invention provide a wireless device/headset 395 that provides and intuitive man machine interface that may be easier to use while, for example, driving a vehicle.

[0044] Referring first to Figure 4, a wireless device/headset 495 in accordance with some embodiments of the present invention will be discussed. As illustrated in Figure 4, the wireless device 495 includes a housing 405 that houses all of the electronics of the wireless headset 495 known to those of skill in the art and a speaker portion 415. The speaker portion 415 is attached to the housing 405. The wireless device 495 is configured to be received by an ear of a user of the wireless device 495 as illustrated in Figure 5. However, it will be understood that although the wireless device 495 is configured to be received by an ear of the user, the wireless device 495 does not have to be used in the ear of the user as will be discussed further below with respect to Figures 8A through 8D.

[0045] Referring again to Figure 4, movement of the housing 415 and/or speaker 405 of the wireless device 495 causes a change in functionality of the wireless device and/or the portable electronic device. The change in functionality of the wireless device 495 and/or the portable electronic device (340, Figure 3) may include, for example, a change in volume to the speaker, initiation of a call received by the portable electronic device, termination of a call received by the portable electronic device and/or muting the speaker of the wireless device. These functions are provided for exemplary purposes only and, therefore, embodiments of the present invention are not limited to the examples.

[0046] In some embodiments of the present invention, the housing 405 is connected to the speaker portion 415 via a joystick switch 425, for example, a 5 -axis joystick switch. As illustrated in Figures 6 and 7, the joystick switch 425 allows the user to move the wireless device up, down, left or right and to push the speaker part 415 in like a button (Figure 7). Each of these movements causes a change in functionality of the wireless device 495 or the portable electronic device 340 (Figure 3) as discussed above.

[0047] As illustrated in Figure 6, in some embodiments of the present invention, the speaker 415 is positioned in the users ear such that the speaker 415 of the wireless device 495 is fixed in the ear of the user. The user may then move the housing 405 of the wireless device 495 left, right, up and down as illustrated in Figure 6 or push the housing 405 in like a button as illustrated in Figure 7. This movement causes the change in functionality of the wireless device 495 and/or portable electronic device 340 (Figure 3).

[0048] As illustrated in Figures 8A through 8D, in some embodiments of the present invention, the wireless device 495 may not be positioned in the ear of a user. In these embodiments, the housing 405 of the wireless device 495 may be fixed in a hand of the user as illustrated in Figure 8 A. As further illustrated in Figure 8A, the user may then move the speaker 415 of the wireless device 495 to cause the change in functionality of the wireless device 495 and/or portable electronic device 340 (Figure 3). In these embodiments, the wireless device 495 may be configured to be used, for example, as a gaming controller for playing games on the portable electronic device and/or a game console as illustrated in Figures 8B and 8C, and as a pointing device for browsing on the portable electronic device or as a pointing device for scrolling and selecting menus on the portable electronic device as illustrated in Figure 8D.

[0049] Operations of wireless devices according to various embodiments of the present invention will now be discussed with respect to the flowcharts of Figure 9 through 1 1. Referring first to Figure 9, operations for operating a wireless device configured to

communicate with a portable electronic device, the wireless device including a housing and a speaker attached to the housing and configured to be received by an ear of a user of the wireless device, begin at block 900 by moving the housing and/or speaker of the wireless device to change functionality of the wireless device and/or the portable electronic device. As discussed above, the functionality of the wireless device and/or the portable electronic device may include, for example, a change in volume to the speaker, initiation of a call received by the portable electronic device, termination of a call received by the portable electronic device and/or muting the speaker of the wireless device. In some embodiments, moving the housing and/or speaker may include moving the housing and/or speaker to cause a joystick switch in the housing to move up, down, left, right or be pushed in like a button. In some embodiments of the present invention, the wireless device may be, for example, a Bluetooth headset. [0050] Referring now to Figure 10, operations for operating a wireless device in accordance with some embodiments of the present invention begin at block 1010 by positioning the speaker attached to the housing in the ear of the user such that the speaker of the wireless device is fixed in the ear of the user. The housing is moved to cause the change in functionality of the wireless device and/or portable electronic device (block 1020). As discussed above, although the wireless device in accordance with some embodiments of the present invention is configured to be positioned in an ear of the user, the wireless device may be use without being positioned in the ear of the user without departing from the scope of the present invention.

[0051] For example, referring to Figure 11, operations begin at block 1130 by positioning the housing of the wireless device in a hand of the user such that the housing is fixed in the hand of the user. The speaker of the wireless device may be moved causing the change in functionality of the wireless device and/or portable electronic device (block 1 140). In these embodiments, the wireless device may be used, for example, as a gaming controller for playing games on the portable electronic device and/or a game console or as a pointing device for browsing menus on the portable electronic device.

[0052] As briefly discussed above, some embodiments of the present invention provide a wireless device/headset having a unique man machine interface that is more intuitive than the small buttons on conventional devices. Accordingly, wireless devices in accordance with some embodiments of the present invention may be easier to use in, for example, a hands free situation like driving a vehicle.

[0053] In the drawings and specification, there have been disclosed exemplary embodiments of the invention. However, many variations and modifications can be made to these embodiments without substantially departing from the principles of the present invention. Accordingly, although specific terms are used, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being defined by the following claims.
