Keeping focus on screen for a long time causes dry eye that makes eyes strain and imposes a burden to your neck, shoulders and arms. This paper proposes a system for the VDT users to prevent dry eye. The proposed system is composed of three functional parts that are blink detection, blink promotion and blink promotion control. The blink detection part detects the blink of the VDT user and send the blink-detected signal to the blink promotion control part in which time interval between the blink-detected signals and total time of the time interval are measured, and control signal is send to the blink promotion part. The blink promotion part is composed of several blink promotion methods and the methods are timely selected and controlled by the control signal corresponding to the blink status. For an experimental evaluation, the proposed system is all implemented on a note-type personal computer using web camera and the image processing. For the blink promotion methods, there are implemented alert sounding, alert text and image displaying on the screen. There also provides changes on display such as color, distortion and contrast so on. Effectiveness of the proposed system is examined.
