Abstract
In four experiments participants were allowed to manipulate a virtual 3-D object in order to infer and draw 2-D cross sections of it. Key differences between the experiments were the interface and degree of interactivity available. Two experiments used a three degrees-of-freedom inertia tracking device allowing unconstrained interactions and the other two experiments used a slider bar that allowed only one degree-of-freedom movement at a time. Somewhat counter-intuitively, we found that the constrained interface allowed people to access task-relevant information more effectively and resulted in better performance on the task.
This research was supported by National Science Foundation grant 0313237 and by a U.S. Department of Homeland Security (DHS) Graduate Fellowship to Peter Khooshabeh under DOE contract number DE-AC05-00OR22750.
