Abstract
The line-of-sight detection system has promising applications in various fields, such as human-computer interaction and marketing. In our previous work, we proposed wearable line-of-sight detection system using micro-fabricated transparent optical sensor on eyeglass and successfully demonstrated line-of-sight detection using the proposed system. However, it required careful calibration with respect to each user and line-of-sight detection even failed for some subjects. We consider that characteristics of the subjects that include shapes of eyes, heights of noses, etc. are the crucial parameters. We investigated which factors are dominant on the reaction rate and the reaction speed of the cells to achieve a practical use.
