Alternative multi-user interaction screen: initial ergonomic test results

Abstract

The authors investigate a potentially low-cost multi-user computer pointing interface. Given a choice of four targets arranged on the screen, the authors looked at what the user’s preference is in visiting the targets with a hand-held light source. The study reveals that the sample group has a preferred starting point when initiating the interaction sequence. In addition, the authors report how some users contorted their bodies during the study.
