Interaction- User Studies

Immersive VR Usability Studies

We have conducted user studies to identify values for the parameters that influence and are dependent on the accuracy with which a user can point at a target object with our immersive VR interaction techniques[FORS96][AYER96][PIER97]. In addition, we are conducting user studies to improve the Sketch interface. The modeling process is accelerated by the gestural nature of the interface, but we believe it is hindered by the indirect nature of the mouse and tablet input devices used to date. We are conducting user studies to compare the accuracy and speed of a mouse, tablet, and light pen for gesture operations. We expect the results to suggest preferred modes of input and influence the future design of the Sketch interface.
