Abstract

Various technologies described herein pertain to managing visual content rendering on a display. Audience presence and position information, which specifies respective distances from the display of a set of audience members detected within proximity of the display, can be obtained. Further, a threshold distance from the display can be determined as a function of the respective distances from the display of the set of audience members detected within proximity of the display. Moreover, responsive to the threshold distance from the display, a size of the visual content rendered on the display can be controlled.

Claims

1. A method of managing visual content rendering for a display, comprising:

receiving location data from mobile devices of audience members and for each of the mobile devices, specifying a corresponding position of the mobile device;

determining respective distances between the display and each of the mobile devices of the audience members detected within proximity of the display based on the location data received from the mobile devices of the audience members detected within proximity of the display;

determining a threshold distance from the display as a function of the respective distances between the display and each of the mobile devices of the audience members detected within proximity of the display, including determining a predefined percentage of a maximum distance from the display, wherein the maximum distance is from the respective distances between the display and the mobile devices of the audience members detected within proximity of the display, wherein the predefined percentage of the maximum distance from the display is less than the maximum distance from the display; and

controlling a size of the visual content rendered on the display based on the threshold distance from the display.

2. The method of claim 1, the size of the visual content comprises at least one of a font size of text rendered on the display or a size of a graphical object rendered on the display.

3. The method of claim 1, wherein determining the threshold distance from the display further comprises determining a maximum distance from the display out of the respective distances between the display and each of the mobile devices of the audience members detected within proximity of the display.

4. The method of claim 1, wherein determining the threshold distance from the display further comprises determining a distance at which the respective distances between the display and a preset percentage of the mobile devices of the audience members detected within proximity of the display are less than or equal to the distance.

5. The method of claim 1, wherein controlling the size of the visual content rendered on the display based on the threshold distance from the display further comprises adjusting the size of the visual content rendered on the display over time as a function of determined changes in the threshold distance from the display over time.

6. The method of claim 5, further comprising inhibiting a subsequent adjustment to the size of the visual content rendered on the display for a predefined period of time after adjusting the size of the visual content rendered on the display.

7. The method of claim 1, further comprising selecting the size of the visual content rendered on the display from a set of predefined discrete sizes as a function of the threshold distance from the display.

8. The method of claim 1, further comprising detecting, based on at least one of a property of the visual content or a property of a document that comprises the visual content, whether to dynamically adjust the size of the visual content rendered on the display as a function of the threshold distance from the display.

9. The method of claim 1, the size of the visual content comprises a thickness of a line generated by a pen on the display.

10. The method of claim 1, further comprising:

detecting whether a document that comprises the visual content comprises formatting that inhibits automatic scaling of the size of the visual content;

enabling the size of the visual content to be dynamically adjusted when the document is determined to lack the formatting that inhibits the automatic scaling of the size of the visual content; and

disabling the size of the visual content from being dynamically adjusted when the document is determined to comprise the formatting that inhibits the automatically scaling of the size of the visual content.

11. The method of claim 1, further comprising detecting that a mobile device is within proximity of the display when the mobile device is in a room in which the display is located.

12. The method of claim 1, further comprising detecting that a mobile device is within proximity of the display when the mobile device is in an area within a predefined distance from the display.

13. A system that facilitates managing visual content rendered on a display, comprising:

a processor; and

a memory that is programmed with instructions that, when executed by the processor, cause the processor to perform acts comprising;

receiving location data from mobile devices of audience members, and for each of the mobile devices, specifying a corresponding position of the mobile device;

generating respective distances between the display and each of the mobile devices of the audience members detected within proximity of the display based on the location data received from the mobile devices of the audience members detected within proximity of the display;

determining a threshold distance from the display as a function of the respective distances between the display and each of the mobile devices of the audience members detected within proximity of the display, including determining a predefined percentage of a maximum distance from the display, wherein the maximum distance is from the respective distances between the display and the mobile devices of the audience members detected within proximity of the display, wherein the predefined percentage of the maximum distance from the display is less than the maximum distance from the display; and

dynamically adjusting a size of the visual content rendered on the display as a function of the threshold distance from the display.

14. The system of claim 13, wherein the size of the visual content rendered on the display comprises at least one of a font size of text rendered on the display or a size of a graphical object rendered on the display.

15. The system of claim 13 comprised in the display.

16. The system of claim 13, the acts further comprising:

receiving a document that comprises the visual content; and

detecting whether to one of enable or disable dynamically adjusting the size of the visual content rendered on the display as a function of the threshold distance from the display based on at least one of a property of the visual content or a property of the document that comprises the visual content.

17. The system of claim 13, wherein the threshold distance from the display is a distance at which the respective distances between the display and a preset percentage of the mobile devices of the audience members detected within proximity of the display are less than or equal to the distance.

18. The system of claim 13, wherein the size of the visual content rendered on the display comprises thicknesses of a first line previously generated by a pen on the display and a second line subsequently generated by the pen on the display.

19. A display, comprising:

a processor; and

a memory that is programmed with instructions that, when executed by the processor, cause the processor to perform acts comprising;

receiving location data from mobile devices of audience members and for each of the mobile devices, specifying a corresponding position of the mobile device;

responsive to receiving the location data from the mobile devices of the audience members, determining respective distances between the display and the mobile devices of the audience members detected within proximity of the display;

determining a threshold distance from the display as a function of the respective distances between the display and the mobile devices of the audience members detected within proximity of the display, including determining a predefined percentage of a maximum distance from the display, wherein the maximum distance is from the respective distances between the display and the mobile devices of the audience members detected within proximity of the display, wherein the predefined percentage of the maximum distance from the display is less than the maximum distance from the display; and

dynamically adjusting a size of visual content rendered on the display as a function of the threshold distance from the display, wherein the size of the visual content comprises a thickness of a line generated by a pen on the display.
