Abstract
Research in eyeball tracking technique has been developed for decades, and has been commercialized. Besides being continuously used in scientific experiments, such as discussing the reaction of human vision toward to different colors or shapes, or analysis one’s psychology state. Some of its applications include: alternative input devices in human-machine interface or recording of the vision of eyes. However, most of the eye-tracking devices have the same defects: complicated calibration procedures and the accuracy are easily affected by head motion. Therefore, it hasn’t been widely used up to now.
In this thesis, author have designed and developed a pupil tracking system which can track with high speed and acquire the location and motion of pupil. This system has twice calculate speed then the previous generation, and much more accurate. Two kinds of artificial eye have been developed driven by servo motor and shape memory alloy. The one driven by servo motor can be control precisely, and the other one with shape memory alloy designed according to human extra-ouclar muscle can operate under low voltage and current quietly. In thesis, we construct a system for evaluating the pupil tracking system with optical system objective.
