Abstract

A system and method for helping ensure that a user of a computer is set up to optimally view the computer monitor under optimal conditions in order to minimize eyestrain. The system includes determining an optimal viewing distance and monitoring the distance of a user from the computer monitor during use of the computer. The system further includes notifying the user when they stray from the optimal viewing distance and further may include testing various aspects of the user'"'"'s eyesight during use of the computer monitor.

2. The system of claim 1, further comprising a communication link between the system and a computer system accessible using a hypertext protocol.

3. The system of claim 1, wherein the display is selected from the group consisting of a CRT monitor, an LCD monitor and a flat panel.

4. The system of claim 3, wherein the first sensor is incorporated into a bezel of the display or a structure supporting the display.

5. The system of claim 1, further comprising at least three light sensors positioned relative to the display to determine a source of multidirectional light.

6. The system of claim 1, wherein the first sensor includes a camera or imaging sensor.

7. The system of claim 6, wherein the camera or imaging sensor is capable of monitoring blink rate of the user.

8. The system of claim 1, further comprising a computer coupled for processing inputs from the first sensor.

9. The system of claim 1, further comprising a cable coupling the first sensor to other portions of the system.

10. The system of claim 1, wherein the first sensor is positioned to monitor the display.

11. The system of claim 1, wherein the first sensor is positioned on top of the display.

12. The system of claim 1, further comprising a remote input device coupled to other portions of the system.
