Electrical shoulder disarticulation and Electrical above elbow prosthesis is applied to patients with high upper limb amputation. This kind of upper extremity prosthesis has danger of contacting with user's face, because it has high DOF mechanism and large working area. To ensure safety, the safety system should monitor position of user's face and prevent user's face from contacting with hand. As methods of estimating position of user's face, there are Stereo vision and TOF (Time of Flight). However, we cannot install these system in Electrical upper extremity prosthesis, because it is unsuitable for complex movement of upper extremity prosthesis. Measuring image by a single camera can estimates distance to face by counting extracted pixel, however, there are some limitations to its use in ensuring safety, mainly that it cannot estimates distance at closely position. To cope with these limitation, in this paper, we report the distance estimation method using low resolution infrared array sensor that can obtains the image of temperature distribution and be installed at significantly low cost and result of accuracy evaluation.
