This paper presents a concept of perception assist with a 3DOF active stereo vision camera system for a 4DOF upper-limb power-assist intelligent exoskeleton system in order to help daily activities of physically weak persons. The proposed active camera system has the capability of moving the camera to a better position to monitor the end effecter of the exoskeleton all the time hence the stereo vision digital camera can be used to monitor the user's interaction with the environment effectively. Based on the environmental information captured by moving camera and other sensors of exoskeleton, user's motion can be modified if problems are found in user's motion. The effectiveness of this proposed system was evaluated by performing experiments.
