GeoGazemarks: Providing Gaze History for the Orientation on Small Display Maps

摘要

Orientation on small display maps is often difficult because the visible spatial context is restricted. This paper proposes to provide the history of a user's visual attention on a map as visual clue to facilitate orientation. Visual attention on the map is recorded with eye tracking, clustered geo-spatially, and visualized when the user zooms out. This implicit gaze-interaction concept, called GeoGazemarks, has been evaluated in an experiment with 40 participants. The study demonstrates a significant increase in efficiency and an increase in effectiveness for a, map search task, compared to standard panning and zooming.
