User interaction in hands-free gaming: a comparative study of gaze-voice and touchscreen interface control

Abstract

The goal of the present study is to contribute to the research on the use of eye tracking in hands-free gaming.We report the results of an experimental study by using a platform game designed by the authors. The game allowedgaze-voice command control, as well touchscreen control of the interface by the player. We employed a set of performancemeasures and we measured player engagement as an indicator of user experience. The findings revealed that the playersdid not improve in game performance when they used the gaze-voice control compared to the touchscreen control. On theother hand, they exhibited stronger engagement, which indicates the potential of gaze-voice combination as an acceptableinteraction method compared to touchscreen in mobile games.
