Compatibility Between Gaze Pointing and the Modern User Interface

Compatibility Between Gaze Pointing and the Modern User Interface

"This study focused on the compatibility between gaze pointing and the Modern user interface (Modern UI) and discussed the effects of layout factors in the Modern UI (tile distance, tile size, type of target tiles, and type of interfering tiles) on the movement time of gaze pointing. A total of 13 participants were recruited, and the movement times of their gaze-pointing operations were measured under 24 experimental scenarios with various values of tile distance, tile sizes, types of target tiles, and types of interfering tiles. According to the results, the speed performance of gaze pointing was determined by tile size rather than tile distance. When the Modern UI was applied in gaze pointing, medium-sized tiles yielded the optimal layout result. The dynamic design of tiles helped participants fixate their gazes steadily on their target tiles and encouraged them to use the tile center as a reference point for gaze pointing. This effect can prevent users from accidentally clicking on tiles adjacent to the target tile, which could possibly occur when the tile edge is used as the reference point. Dynamic interfering tiles did not diminish the operational performance of gaze pointing."
