Perceptual Interfaces are concerned with extending human computer interaction to use all modalities of human perception. Our current research efforts are focused at including vision, audition, and touch in the process. The goal of perceptual reality is to create virtual and augmented versions of the world, that are perceptually identical to the human with the real world. The goal of creating perceptual user interfaces is to allow humans to have natural means of interacting with computers, appliances and devices using voice, sounds, gestures, and touch. In both creating virtual reality, and in acquiring multimodal input from humans, our research emphasizes physics-based algorithms, efficient computation, and real-time implementations.

 Another portion of our research is concerned with creating prosthetic devices for the vision and hearing impaired, by mapping inputs from one modality into equivalent ones in another, so that computationally augmented input streams can be created with extra content from the missing modality.
