"This is a lot easier!": constrained movement speeds navigation

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