Blink Don't Wink: Exploring Blinks as Input for VR Games
Mikkel Rosholm Rebsdorf, Theo Khumsan, Jonas Valvik, Niels Christian Nilsson, Ali Adjorlu · 2023
Eye tracking enables several novel ways of interacting with virtual reality (VR) games, yet research on blink interaction techniques (BITs) in VR remains scarce. This short paper introduces a preliminary design space for BITs in VR and describes an exploratory user study comparing five games designed around five BITs. Results from questionnaires indicate that the BITs were satisfactory, and qualitative feedback highlight factors influencing players’ preferences and the importance of considering fatigue from high blink rates and potential accessibility limitations of single-eyed interactions.
