Towards using Eye Gaze Redirection in Immersive Reading Tasks for Visual Fatigue Reduction

Visual fatigue poses a significant challenge in Human-Information Interaction (HII) in VR. Target redirection, a method that helps mitigate shoulder fatigue, could potentially help reduce visual fatigue by guiding our eyes to move in certain ways. This paper proposes a study using eye movement redirection in VR to reduce visual fatigue from immersive HII tasks. We highlight two primary challenges, speed and range of redirection, that directly impact the user experience and effectiveness. We further introduce two studies aimed at tackling these problems: 1) to find the best parameters for redirection and 2) to evaluate the technique's usability. We hypothesize that this innovative approach will greatly contribute to user-friendly and safe gaze-based HII in VR, enhancing user experience and performance by reducing visual fatigue.
