Result of a perceptual feedback of the grasping forces to prosthetic hand users

This paper describes a sensor based control that releases the user from the continuous attention usually required in opening and closing actions. Further to this local control, the sensory information is used to generate some feedback to the user for the perception of the progress of the hand operation. We are also presented a study and result about the learning and adaptation of the electric signals that are used for the feedback in user and patients in UPC and Vall dpsilaHebron Hospital.
