Interaction with 3D models on large displays using 3D input techniques

Almost all existing 3D modeling applications rely on 2D input techniques for creating and modifying 3D models by users. This translation of user inputs from a 2D plane into actions in a 3D world often causes problems for modelers when moving, placing, rotating and transforming 3D objects. Although several 3D input techniques have been developed in the past, these have generally relied on expensive technology such as haptic or immersive devices. In this paper we investigate the possibility of using affordable devices, including the Nintendo Wii Controller (Wiimote) and conventional webcams, as means of interacting with 3D models on large displays. A pilot user study of these techniques has also been carried out, and the results are presented here
