Modelling of Eye-Hand Motions in a Common 3D Coordinate System
Eyes and hands are continuously in movement but the quantitative evaluation of the coordination between these motions is still unclear. This paper presents a new methodology to explain how these motions are executed in a common spatial coordinate system providing an accurate diagnostic tool for motor control disorders. A robot, an eye-tracker and a movement analysis system were used to capture the upper extremity and eye motions. The joint angles were calculated using a biomechanical model and a global point of gaze was encountered in relation to the focused object.
