Effects of Motion Estimation and Motion Compensation (MEMC) on Reducing Visual Fatigue When Playing Games: A Prospective Randomized Controlled Study

Visual fatigue, a hallmark of CVS, is particularly prevalent among mobile gamers who engage in prolonged gaming sessions. The dynamic visual stimuli in modern games-characterized by rapid movements, high refresh rates, and intricate details-place substantial strain on the oculomotor system, leading to symptoms like eye discomfort, reduced concentration, and even cognitive fatigue. Studies have shown that gaming on smartphones can exacerbate visual fatigue. These effects are often compounded by suboptimal viewing conditions, such as improper lighting or prolonged near-work distances, which are common during mobile gaming. Given the growing popularity of mobile gaming, there is an urgent need to address visual fatigue in this context to enhance user comfort and prevent long-term ocular health issues.

The investigators hypothesize that MEMC-enabled devices may reduce the physiological and cognitive burden of visual fatigue by improving motion clarity and minimizing oculomotor strain. To test this, the investigators comparing MEMC-enabled and standard gaming experiences, this study provides insights into differences in visual health indicators, cognitive load, and physiological responses. These findings aim to inform the development of display technologies and usage guidelines that promote healthier interactions with smartphones, particularly for reducing visual fatigue and prolonged gaming scenarios.
