ABSTRACT
This chapter discusses how eye-trackers in general, and gaze-contingent displays in particular, have been used by psychologists in the past in different applications. It presents a brief overview of gaze-contingent multiresolution displays and how they can be used for image and video compression, and for foveated imaging. The chapter presents a detailed overview of our work on gaze-contingent multimodality display (GCMMD) including a number of different applications such as two-dimensional image fusion, three-dimensional volumetric image fusion and multilayered map perception. It discusses implementation and performance issues for several different GCMMDs, and also how various eye-trackers can be integrated in such systems. “Multimodality” is a term used, within the literature, with slightly different meanings. Within psychology and other human-centered sciences, it is often taken to mean the use of multiple [human] senses to perceive, or interact with, data.
