Establishing a Theory of Eye Gaze and Eye movement --- The Shift from Non-Linguistic to Linguistic

手语中的眼球注视和眼球运动是语言元素。一些印度舞蹈有眼睛注视和眼睛运动的规则。我进行了眼动追踪实验，以研究舞者和手语者如何产生眼睛注视和眼球运动，并开发了一种方法来记录电视显示器上图像中瞳孔的位置和运动。研究表明，手语的眼球注视和眼球运动具有高度的语言性，晚期学习者和非手语学习者的手势表达比母语学习者和早期学习者更多地具有非语言性的眼球注视和眼球运动。

Eye gaze and eye movement in sign languages are linguistic elements. Some of Indian dances have rules of eye gaze and eye movement. I conducted eye tracking experiments to examine how dancers and signers produce eye gaze and eye movement and also developed a way to record positions and movements of pupils in the image on the TV monitors. It became clear that eye gaze and eye movement in sign languages are highly linguistic and the sign expression by late learners and non-signers have non-linguistic eye gaze and eye movement more often than native signers and early learners. .
