Coordinate transformation learning of hand position feedback controller with time delay
نویسندگان
چکیده
The speed, accuracy, and adaptability of human movement depends on the brain performing an inverse kinematics transformation*i.e., a transformation from visual to joint angle coordinates*based on learning from experience. In human visually guided motion control, it is important to learn a feedback controller for the hand position error. This paper proposes two novel models that learn coordinate transformations of the human visual feedback controller with time delay. The proposedmodels redress drawbacks in current models because they do not rely on complex signal switching, which does not seem neurophysiologically plausible. 2001 Published by Elsevier Science B.V.
