Outline of the Course

How traditional human-computer-interaction methodologies augmented with theories and experimental findings from cognitive science address challenges posed by multimodal interaction using vision, haptics, and sound in conventional and immersive computer graphics environments. Attendees learn the theory and practice of multimodal interaction design in a multidisciplinary setting.

Outline of this Section

As casual observers, we tend to believe that vision is based on representations that are coherent and complete, with everything in the visual field described in great detail. However, changes made during a visual disturbance are found to be difficult to see, arguing against this idea. Instead, it is argued that vision is based upon a more dynamic, "just-in-time" representation, one with deep similarities to the way that users interact with external displays. Several suggestions are put forward as to how these similarities can be harnessed for the design of intelligent display systems that interact with humans in highly effective and novel ways.
