Abstract

A method can include rendering pixel representations of information to a rectangular display; and rendering pixel representations of perspectival text to the rectangular display where the pixel representations of perspectival text overlay a portion of the pixel representations of information. Various other methods, apparatuses, systems, etc., are also disclosed.

Claims

1. A method comprising:

rendering pixel representations of information to a rectangular display; and

rendering pixel representations of perspectival text to the rectangular display wherein the pixel representations of perspectival text overlay a portion of the pixel representations of information.

2. The method of claim 1 wherein the pixel representations of perspectival text comprises at least one perspective associated with a point of view displaced from a vector normal to the rectangular display.

3. The method of claim 1 wherein the pixel representations of information comprises a perspective associated with a point of view substantially along a vector normal to the rectangular display.

4. The method of claim 1 further comprising detecting an object in a field of view of the rectangular display, determining a point of view for the object and rendering the pixel representations of perspectival text to the rectangular display based at least in part on the point of view of the object.

5. The method of claim 1 further comprising periodically rendering pixel representations of different perspectival text to the rectangular display.

6. The method of claim 1 comprising generating the perspectival text using a database.

7. The method of claim 1 comprising randomly selecting the perspectival text.

8. The method of claim 1 wherein the perspectival text comprises at least one color.

9. The method of claim 1 wherein the pixel representations of information comprise a color and wherein the pixel representations perspectival text comprise a different color.

10. A system comprising:

a processor;

memory operatively coupled to the processor;

a rectangular display operatively coupled to the processor;

display circuitry that receives information from the processor and that renders pixel representations of the information to the rectangular display and that renders pixel representations of perspectival text to the rectangular display wherein the pixel representations of the perspectival text overlay at least a portion of the pixel representations of the information.

11. The system of claim 10 wherein the display circuitry comprises circuitry that randomly selects the perspectival text.

12. The system of claim 10 comprising a sensor that senses objects in a field of view of the rectangular display and selection circuitry that selects a perspective for the pixel representations of perspectival text based at least in part on a sensed object in the field of view of the rectangular display.

13. The system of claim 12 wherein the selection circuitry selects multiple perspectives for pixel representations of perspectival text based at least in part on sensed objects in the field of view of the rectangular display.

14. The system of claim 10 wherein the pixel representations of perspectival text comprise at least one perspective associated with a point of view displaced from a vector normal to the rectangular display.

15. The system of claim 10 wherein the pixel representations of information comprise a perspective associated with a point of view along a vector normal to the rectangular display.

16. One or more computer-readable storage media comprising processor-executable instructions to instruct an information handling system to:

render pixel representations of information to a rectangular display; and

render pixel representations of perspectival text to the rectangular display wherein the pixel representations of perspectival text overlay a portion of the pixel representations of information.

17. The one or more computer-readable storage media of claim 16 wherein the pixel representations of perspectival text comprise at least one perspective associated with a point of view displaced from a vector normal to the rectangular display.

18. The one or more computer-readable storage media of claim 16 wherein the pixel representations of information comprise a perspective associated with a point of view along a vector normal to the rectangular display.

19. The one or more computer-readable storage media of claim 16 comprising instructions to instruct an information handling system to sense objects in a field of view of the rectangular display and to select a perspective for the pixel representations of perspectival text based at least in part on a sensed object in the field of view of the rectangular display.

20. The one or more computer-readable storage media of claim 16 comprising instructions to instruct an information handling system to periodically render pixel representations of different perspectival text to the rectangular display wherein the pixel representations of different perspectival text overlay a portion of the pixel representations of the information.
