Augmented Reality (AR) for Assembly Processes?? An Experimental Evaluation

A PAL-video-camera (Toshiba ACM 413 E with 2,2 mm lens) and a HMD have been connected to a Silicon Graphics Workstation O2 (SGI). As HMD a Clip-on display (MircoOptical) with a 640 x 480 resolution has been taken. The Clip-on display can be used like other HMDs in video see-through mode. It works like a little monitor in front of the user’s eyes which covers just a small part of his field of view. On the one hand it needs not to be re-calibrated for each AR-sequence contrary to optical see-through displays. On the other hand the assembling person was not restricted by the inconveniences of the video see-through mode like latency, focus, etc which are quite bothersome for assembly.
