Spatial input device structure and bimanual object manipulation in virtual environments

Complex 3D interaction tasks require the manipulation of a large number of input parameters. Spatial input devices can be constructed such that their structure reflects the task at hand. As such, somatosensory cues that a user receives during device manipulation, as well as a users expectations, are consistent with visual cues from the virtual environment. Intuitively, such a match between the device’s spatial structure and the task at hand would seem to allow for more natural and direct interaction. However, the exact effects on aspects like task performance, intuitiveness, and user comfort, are yet unknown. The goal of this work is to study the effects of input device structure for complex interaction tasks on user performance. Two factors are investigated: the relation between the frame of reference of a user’s actions and the frame of reference of the virtual object being manipulated, and the relation between the type of motion a user performs with the input device and the ...
