Abstract
In a medical diagnostic apparatus utilizing line-of-sight detection, targets are successively presented from different angles to the subject by a target presenting apparatus, eye movement of the subject while the subject is gazing at the target is detected by an eye movement detecting portion, the head movement of the subject is detected by a head movement detecting portion, and in response to the detection outputs, the spatial movement of the line-of-sight, rotation velocity component and translational velocity component of the head movement as well as the velocity component of the eye movement are calculated by a calculating portion, and the results are output to an output portion.
