Abstract

A method, apparatus, and program product are disclosed for receiving a proximity input indicator signal associated with an information handling device, the information handling device comprising a display, determining a proximity of a user to the information handling device based on the proximity input indicator signal, and modifying one or more display settings of the information handling device in response to the determined proximity.

First claim

What is claimed is:

1. An apparatus comprising:
an information handling device comprising a display;
a processor operatively coupled to the information handling device;
an input module that receives a proximity input indicator signal associated with the information handling device in response to detecting that a usage mode of the information handling device changes between a laptop mode and a tablet mode;
a proximity module that determines a proximity of a user to the information handling device in response to the received proximity input indicator signal; and
a settings module that modifies one or more display settings of the information handling device based on the determined proximity.

2. The apparatus of claim 1 , wherein the input module further comprises a mode module that receives a proximity input indicator signal from a mode detector, the mode detector determining a usage mode of the information handing device.

3. The apparatus of claim 2 , wherein the mode module receives a proximity input indicator signal in response to the mode detector detecting a detachable keyboard being one of coupled to the information handling device and uncoupled from the information handling device.

4. The apparatus of claim 3 , wherein the proximity input indicator signal comprises a docked mode signal in response to the information handling device being coupled to the detachable keyboard and a handheld mode signal in response to the information handling device being uncoupled from the detachable keyboard.

5. The apparatus of claim 1 , wherein the input module further comprises a sensor module that receives a proximity input indicator signal from a sensor operably coupled to the information handling device.

6. The apparatus of claim 5 , wherein the sensor comprises one of a three-dimensional (“3D”) camera, an infrared camera, and a proximity sensor.

7. The apparatus of claim 1 , wherein the settings module further comprises a display module that adjusts a resolution of the display according to the determined proximity.

8. The apparatus of claim 1 , wherein the settings module further comprises a text module that adjusts the size of text presented on the display according to the determined proximity.

9. The apparatus of claim 8 , wherein the text module adjusts the size of text presented on the display without adjusting the size of other items presented on the display.

10. The apparatus of claim 1 , further comprising a timing module that, in response to the determined proximity, starts a timer set for a predetermined period of time, wherein the settings module adjusts the one or more display settings in response to expiration of the timer.

11. The apparatus of claim 1 , further comprising a configuration module that sets one or more parameters associated with the display settings in response to user input.

12. A method comprising:
receiving a proximity input indicator signal associated with an information handling device in response to detecting that a usage mode of the information handling device changes between a laptop mode and a tablet mode, the information handling device comprising a display;
determining, by use of a processor, a proximity of a user to the information handling device in response to the received proximity input indicator signal; and
modifying one or more display settings of the information handling device based on the determined proximity.

13. The method of claim 12 , further comprising receiving a proximity input indicator signal from a mode detector, the mode detector determining a usage mode of the information handing device.

14. The method of claim 13 , wherein the proximity input indicator signal is received in response to the mode detector detecting a detachable keyboard being one of coupled to the information handling device and uncoupled from the information handling device.

15. The method of claim 12 , further comprising receiving a proximity input indicator signal from a sensor operably coupled to the information handling device.

16. The method of claim 12 , further comprising adjusting a resolution of the display according to the determined proximity.

17. The method of claim 12 , further comprising adjusting the size of text presented on the display according to the determined proximity.

18. The method of claim 17 , wherein the size of text presented on the display is adjusted without adjusting the size of other items presented on the display.

19. The method of claim 12 , further comprising starting a timer set for a predetermined period of time in response to the determined proximity, wherein the one or more display settings are adjusted in response to expiration of the timer.

20. A program product comprising a non-transitory computer readable storage medium that stores code executable by a processor to perform:
receiving a proximity input indicator signal associated with an information handling device in response to detecting that a usage mode of the information handling device changes between a laptop mode and a tablet mode, the information handling device comprising a display;
determining a proximity of a user to the information handling device in response to the received proximity input indicator signal; and
modifying one or more display settings of the information handling device based on the determined proximity.
