Abstract

This paper reports on an experiment comparing constrained and unconstrained movement in a 2D zooming environment. Results showed a significant reduction in time on task when movement was constrained, accompanied by considerable decreases in mouse movement activity. Detailed analysis suggests that subjects were calmer, more confident in their actions and experienced less spatial disorientation, indicating that judiciously constrained movement can reduce both mechanical and cognitive demands of navigation.
