 More Information

Clifton Forlines is Research Associate at MERL. His research interests include the design and evaluation of novel user interfaces. Current research projects span from three-dimensional presentation of and navigation through recorded digital video, to collaborative tabletop user interfaces, to using hand-held projectors for augmented reality. He is currently leading the evaluation of three projects, MediaFinder, TimeTunnel, and DiamondSpin. Before coming to MERL, Clifton worked on Carnegie Mellon's Alice project, which aimed at teaching programming to children through building interactive 3D worlds.

Recent Projects:

DiamondSpace
DiamondTouch
LucidTouch - A See-through 2-sided Touch Mobile Device
