Introducing tactile feedback into closed-loop control of prosthetic hand has always been an issue to provide amputees with a kind of more use-friendly and efficient prosthesis. This paper describes a method to improve prosthetic closed-loop control performance via slipping feedback. Cognitive load task is introduced into the system to verify whether the slip feedback adding much attention. The results show that with slip and visual feedback, subjects could finish grasp task more stably and faster than that only with visual feedback. And there are little difference on cognitive load task between slip & visual feedback and visual feedback.
