Eye movements and smart technology.

From a cognitive science/artificial intelligence perspective, this paper identifies the scanpath concept as the instantiation of a general sequencing principle that permeates the organization of spatial scene knowledge throughout the levels of mental processing. As such, it helps create methodologies to open up windows onto higher-level cognitive processes, particularly by relating shifts of visual focus to shifts of attention in mental reasoning. The paper argues that these methodologies form a robust basis for smart applications that employ eye movements to assess and to assist in diagrammatic problem solving.
