Abstract
To search the factor of motion sickness, measurement of rotational eye movement is required to be robust in the dark. But it is difficult to obtain accuracy because iris patterns highly deform in the dark. There is a method of widely searching whether to presume the position of the moving pattern from the model to make the match with the transformed pattern succeed. But it takes time to the method for the request from the model to process the method of the wide-ranging search while the error margin occurs too much. This study proposes the method by which a wide-ranging search can be carried out with a high-speed algorithm so as to be robust in the dark.
