The Application of Eye Tracking on User Experience in Virtual Reality

The field of human-computer interaction in virtual reality (VR) has been extensively researched in recent years. In addition to the traditional interaction with the head-mounted displays and handles of VR devices, eye-based (i.e., gaze) interaction is also a possible research direction. Most of the eye-based interactions in VR that have been demonstrated to be possible so far use eye movement for object selection, but there is very little research into eye movement as a separate interaction method. This study aims to explore the feasibility and user experience of applying eye-tracking technology as an interaction method in virtual worlds. This study investigates interaction methods by applying eye-tracking interaction in VR and combining eye interaction with hand interaction. In addition, eye tracking was used to collect all eye-related data generated by the participants during the experiment. The results of the study show that eye-tracking interaction is rated as the most favorable and the most controlled interaction method, but the feasibility of hand-eye interaction is still to be investigated and debated. This study demonstrates that the use of eye-movement interaction as the primary interaction method is a novel direction and a useful input method.
