Wands Are Magic: A Comparison of Devices Used in 3D Pointing Interfaces

Abstract : In our pilot study with 12 participants, we compared three interfaces, 3D mouse, glove and wand in a 3D naturalistic environment. The latter two were controlled by the same absolute pointing method and so are essentially identical except for the selection mechanism, grasp action versus button. We found that the mouse performed worst in terms of both time and errors which is reasonable for a relative pointing device in an absolute pointing setting, with the wand both outperforming and favored by users to the glove. We conclude that the presence of a held object in a pointing interface changes the user’s perception of the system and magically leads to a different experience.
