A Three-Stage Visual Training Evaluation Based on the METUX Model: Motivation, Engagement, and Well-Being

This study presents a visual training design based on the Motivation, Engagement, and Thriving in User Experience (METUX) model to address low patient motivation and participation. It introduces a proactive approach by incorporating a playful scenario that alleviates digital eye strain and improves training outcomes. The study employs a three-phase experimental design: (1) validating the feasibility of visual training without additional equipment burden, (2) investigating the effects of gaze-controlled cursor movement on motivation and engagement, and (3) evaluating the impact of a playful training environment on well-being. Real-time eye-tracking is conducted using MediaPipe, with visual feedback provided through TouchDesigner, alongside data collection via physiological sensors. This research aims to transition visual training from passive to active, minimizing equipment complexity and enhancing user experience in vision regulation.
