Abstract

In accordance with the teachings of the present disclosure, a touch-screen device may include a touch-screen display and a display manager. The touch-screen display may include a display device configured to display at least one of graphical images and alphanumeric text and a touch sensor configured to detect a tactile touch proximate to the touch sensor. The display manager may be configured to receive an indication of a manifestation of a desire of a user of the touch-screen device to disable at least a portion of the touch sensor and in response to the indication, disable at least a portion of the touch sensor while maintaining a display present on the display device substantially similar to that immediately before the user manifested the desire to disable at least a portion of the touch sensor.

Claims

1. A touch-screen device comprising:

a touch-screen display having;

a display device configured to display at least one of graphical images and alphanumeric text; and

a touch sensor configured to detect a tactile touch proximate to the touch sensor; and

a display manager configured to;

receive an indication of a manifestation of a desire of a user of the touch-screen device to disable at least a portion of the touch sensor; and

in response to the indication, disable at least a portion of the touch sensor while maintaining a display present on the display device substantially similar to that immediately before the user manifested the desire to disable at least a portion of the touch sensor.

2. A touch-screen device in accordance with claim 1, the touch-screen device comprising a processor, wherein the display manager comprises a program of instructions configured to execute on the processor.

3. A touch-screen device in accordance with claim 1, the touch sensor configured to:

detect an interaction of a user with the touch-screen display indicative of the manifestation of the desire of the user to disable at least a portion of the touch sensor; and

communicate to the display manager the indication of the manifestation of the desire of the user to disable at least a portion of the touch sensor in response to detecting the interaction.

4. A touch-screen device in accordance with claim 3, the interaction comprising at least one of a touch indicative of the desire to disable the touch sensor and a gesture indicative of the desire to disable the touch sensor.

5. A touch-screen device in accordance with claim 3, the interaction comprising input of a code indicative of the desire to disable the touch sensor.

6. A touch-screen device in accordance with claim 1, further comprising an input device configured to:

detect an interaction of a user with the input device indicative of the manifestation of the desire of the user to disable at least a portion of the touch sensor; and

communicate to the display manager the indication of the manifestation of the desire of the user to disable at least a portion of the touch sensor in response to detecting the interaction.

7. A touch-screen device in accordance with claim 6, the input device comprising a button.

8. A touch-screen device in accordance with claim 7, the interaction comprising depressing the button for a duration of time.

9. A touch-screen device in accordance with claim 8, the button configured to:

detect a second interaction of the user indicative of a manifestation of the desire of the user to place the touch-screen device in a standby mode in order disable at least a portion of the touch sensor and disable the display device while leaving other components of the touch-screen device in a powered state; and

communicate to the display manager the indication of the manifestation of the desire of the user to place the touch-screen device in the standby mode in response to detecting the second interaction.

10. A touch-screen device in accordance with claim 9, the second interaction comprising depressing the button for a second duration of time.

11. A touch-screen device in accordance with claim 8, the button configured to:

detect a second interaction of the user indicative of a manifestation of the desire of the user to power off the touch-screen device; and

communicate the indication of the manifestation of the desire of the user to power off the touch-screen device.

12. A touch-screen device in accordance with claim 11, the second interaction comprising depressing the button for a second duration of time.

13. A touch-screen device in accordance with claim 6, the input device comprising a biometric sensor.

14. A touch-screen device in accordance with claim 6, the input device comprising an accelerometer configured to detect at least one of a motion of the touch-screen device and orientation of the touch-screen device, wherein the interaction comprises at least one of a particular movement of the touch-screen device and placement of the touch-screen device in a particular orientation.

15. A touch-screen device in accordance with claim 1, a display manager configured to, while at least a portion of the touch-screen is disabled:

receive a second indication of a manifestation of a desire of the user of the touch-screen device to enabled the touch sensor; and

in response to the second indication, enable the touch sensor.

16. A touch-screen device in accordance with claim 1, the touch sensor configured to:

detect an interaction of a user with the touch-screen display indicative of the manifestation of the desire of the user to enable the touch sensor; and

communicate to the display manager the indication of the manifestation of the desire of the user to enable the touch sensor.

17. A touch-screen device in accordance with claim 1, further comprising an input device configured to:

detect an interaction of a user with the input device indicative of the manifestation of the desire of the user to enable the touch sensor; and

communicate to the display manager the indication of the manifestation of the desire of the user to enable the touch sensor in response to detecting the interaction.

18. A touch-screen device in accordance with claim 17, the input device comprising one of a button, a biometric reader, and an accelerometer.

19. A method comprising:

receiving an indication of a manifestation of a desire of a user of a touch-screen device to disable at least a portion of a touch sensor, the touch-screen device comprising a touch-screen display comprising the touch sensor; and

in response to receiving the indication, disabling at least a portion of the touch sensor while maintaining a display present on a display device substantially similar to that immediately before the user manifested the desire to disable at least a portion of the touch sensor, the touch-screen display comprising the display device.
