My research focuses on three-dimensional user interfaces (3D UIs) and interaction techniques, and immersive virtual environments (VEs). My research group (the 3DI group) has recently been looking at information-rich virtual environments (IRVEs), the benefits of immersion, and domain-specific 3D interaction. Much more information is available on the 3DI group website.
My dissertation research concentrated on interaction techniques for immersive virtual environments. In other words, I designed and evaluated techniques by which users can perform tasks within a 3D virtual world. I focused on common tasks such as travel (viewpoint motion control), selection, and manipulation.
