OKN EYE MOVEMENTS IN RECOGNITION OF MOVING TEXT
OKN眼动跟踪在运动文字识别中的作用

Eye-movement experiment for recognizing and reading moving Chinese text are performed. The experimental results show: (1) The eye-movement pattern during recognition of moving text is Optokinetic nystagmus ( OKN) . There are no fixation pauses and the content information is acquired during the velocity tracking. These results indicate that content information and velocity information are processed in parallel. (2) The maximum velocity of the moving text for eliciting OKN is much faster than that for recognition of moving text. Therefore , the OKN is not the effect of recognition, it is a precondition for recognition of moving pattern. (3) The reading rate measured for moving text is not less than that for normal reading. Our results also indicate that the fast phase of OKN is different from foveating saccades.
