Abstract

Systems and methodologies for adapting input/output operation of an electronic device for in-hand and out-of-hand scenarios are provided herein. As described herein, sensors (e.g., capacitive, resistive, touch-sensitive, etc.) are applied to respective outer edges of a device to determine whether the device is in a user'"'"'s hand. Subsequently, the determination can be utilized to automatically select an input/output mode for the device and to selectively activate one or more input/output mechanisms associated with the device. For example, if a device is determined to be in-hand, mechanical input/output mechanisms, such as a touch-screen or keypad, can be enabled. Alternatively, if a device is determined to be out-of-hand, a touch-screen at the device can be disabled to conserve power and alternative input/output mode, such as voice input/output, can be enabled. As further described herein, in- and/or out-of-hand behavior for a device can be specified on a per-application or per-application type basis.

Claims

1. A system that facilitates controlling input/output (I/O) mechanisms associated with an electronic device, comprising:

one or more sensors located at respective edges of an electronic device that obtain information relating to presence of fingers or hands of a user relative to the edges of the electronic device;

an in/out of hand detector that determines whether the electronic device is in a hand of the user based on the information obtained from the one or more sensors; and

an I/O selector that selectively activates one or more I/O mechanisms at the electronic device based at least in part on the determination by the in/out of hand detector.

2. The system of claim 1, wherein the I/O selector activates one or more of a touch screen or a display screen and deactivates one or more of a microphone or a speaker upon a determination by the in/out of hand detector that the electronic device is in the hand of the user.

3. The system of claim 1, wherein the I/O selector activates input from the one or more sensors upon a determination by the in/out of hand detector that the electronic device is in the hand of the user.

4. The system of claim 1, wherein the I/O selector activates one or more of a microphone or a speaker and deactivates one or more of a display screen or a touch screen upon a determination by the in/out of hand detector that the electronic device is out of the hand of the user.

5. The system of claim 4, wherein the I/O selector activates one or more of a microphone or a speaker associated with a disparate unit from the electronic device.

6. The system of claim 1, wherein the I/O selector further selectively activates one or more I/O mechanisms at the electronic device based on one or more applications running at the electronic device.

7. The system of claim 6, wherein the I/O selector activates a display screen and one or more speakers upon a determination by the in/out of hand detector that the electronic device is out of the hand of the user and a determination that a video application is running at the electronic device.

8. The system of claim 6, wherein the I/O selector deactivates a display screen and activates input from the one or more sensors, a speaker, and a microphone upon a determination by the in/out of hand detector that the electronic device is in the hand of the user and a determination that a voice communication application is running at the electronic device.

9. The system of claim 1, wherein:

the one or more sensors include respective arrays of sensing points and a presence detector that obtains information relating to presence of contact with the respective arrays of sensing points, and

the in/out of hand detector determines whether the electronic device is in a hand of the user based on the information obtained by the presence detector.

10. The system of claim 1, wherein the electronic device is a mobile telephone handset.

11. The system of claim 1, wherein the electronic device is one or more of a handheld electronic game system or an electronic game controller.

12. A method of adapting an electronic device for in-hand or out-of-hand operation, comprising:

monitoring state of one or more sensors affixed to respective outer edges of an electronic device;

determining whether the electronic device is in or out of a hand of a user based on the monitored state of the one or more sensors; and

selecting an input/output (I/O) mode to be utilized by the electronic device based at least in part on the determination of whether the electronic device is in or out of the hand of the user.

13. The method of claim 12, wherein the selecting comprises activating a display I/O mode upon a determination that the electronic device is in the hand of the user.

14. The method of claim 12, wherein the selecting comprises enabling input at the one or more sensors upon a determination that the electronic device is in the hand of the user.

15. The method of claim 12, wherein the selecting comprises activating a voice I/O mode upon a determination that the electronic device is out of the hand of the user.

16. The method of claim 15, wherein the activating a voice I/O mode comprises enabling one or more microphones or speakers that are separate from the electronic device.

17. The method of claim 15, wherein the selecting comprises selecting an I/O mode to be utilized by the electronic device based at least in part on one or more applications executing at the electronic device.

18. The method of claim 17, wherein the selecting further comprises activating a display and a voice I/O mode upon a determination that the electronic device is out of the hand of the user and that a video application is executing at the electronic device.

19. The method of claim 17, wherein the selecting further comprises disabling a display, activating a voice I/O mode, and enabling input at the one or more sensors upon a determination that the electronic device is in the hand of the user and that a voice communication application is executing at the electronic device.

20. A system that facilitates automatic input/output (I/O) adaptation for a handheld device, comprising:

means for sensing presence of one or more hands or fingers of a user with respect to respective edges of a device;

means for determining whether the device is located in a hand of a user based on the sensing; and

means for selecting and activating one or more display I/O devices or voice I/O devices based on the determination of whether the device is located in a hand of the user.
