A physio-anthropological study of the POS system space scanner

Yasuyuki Kikuchi; Tetsuo Katsuura; Akira Okada; Chang-franw Lee

Abstract 1. 1. We compared the functions of POS system scanners by measuring electromyograms and joint angles during scanning in this paper. 2. 2. We have demonstrated that the space scanner is physically easy to use, movement of the wrist is natural and easy, the most suitable method for scanning perishable foods which spill easily or are fragile. 3. 3. A space scanner can be used with a bar code. 4. 4. Electromyograms were taken from M. deltoideus, M. biceps brachii, M. extensor carpi radialis longus and brevis, M. flexor carpi ulnaris muscles.
