Empirical Evaluation of Performance in Hybrid 3D and 2D Interfaces

Experimental studies of spatial input devices have focused on demonstrating either the superiority of 3D input devices over 2D input devices, or the superiority of bimanual interaction over unimanual interaction. In this paper, we argue that hybrid interfaces that combine a 3D input device with a 2D input device have received little attention up to now and are potentially very useful. We demonstrate by means of an experimental evaluation that working with hybrid interfaces can indeed provide superior performance compared to strictly 3D and 2D interfaces.
