P‐4.2: High‐Precision Human Eye Simulation Device
Guanghang Mei, Xiaochen Zhou, Shunli Zang, Tao He, Lei Zhao · SID Symposium Digest of Technical Papers · 2024
Simulation equipment designed to replicate human eye movement, encompassing saccades, gaze, and other nuances, proves invaluable in eye movement tests, serving as an effective substitute for human subjects. Functioning as a reliable value system, it excels in ensuring precision in measurements and facilitating systematic analysis. This article introduces the design of a human eye simulation device featuring a unique dual‐axis motor structure. This design allows for the controlled rotation of the simulated eyeball without the need to move the entire device. Subsequently, a motion control algorithm is developed based on the coupling relationship of poses during dual‐axis rotation, facilitating precise control of the line of sight angle. Finally, an objective comparison of test data between real human eyes and the simulated eye device is conducted, validating the efficacy of the latter.
