Research Interests

My research at the University of Toronto focused on design and evaluation of 3D human machine interfaces (both displays and input controls) for manipulation tasks.

On the display side, I worked on stereoscopic graphics and video for telerobotic control (the ARGOS project) [1] , [2] , [3] , [4] . With Bill Buxton and Paul Milgram, I developed a technique, the "Silk Cursor" [5] that utilizes semi-transparent surfaces for interaction in 3D. I have also studied the anisotropic performance in 3D display [6].

On the input control side, I analyzed human performance with various types of 6 DOF controls. Follow this link for an overview of my research on the Human Factors in 6 DOF Input, [7], [8], [9], [10], [11] .

I was invloved in studies on task network modelling of human performance [12] , analysis of vehicle navigation aids [13], Palm-top VR [14] , and icons in interface design [15].
