The More You Look the More You Get: Intention-based
Interface using Gaze-tracking
Only a decade ago eye- and gaze-tracking technologies using cumbersome and expensive equipment were confined to university research labs. However, rapid technological advancements (increased processor speed, advanced digital video processing) and mass production have both lowered the cost and dramatically increased the efficacy of eye- and gaze-tracking equipment. This opens up a whole new area of interaction mechanisms with museum content. In this paper I will describe a conceptual framework for an interface, designed for use in museums and galleries, which is based on non-invasive tracking of a viewer's gaze direction. Following the simple premise that prolonged visual fixation is an indication of a viewer's interest, I dubbed this approach intention-based interface.
