The Design and Experimental Study of Eye-hand Integrated Dual-channel Interaction Strategies

With societal and technological advancements, human-computer interaction design now emphasizes ease of use and user experience. This paper addresses issues in single-channel eye-control interactions by integrating eye and hand control. We propose two dualchannel strategies: “eye control lock-hand control trigger” and “gaze browsing positioning-hand control state switching-eye control trigger”. Using Unity and Tobii eye tracker, we developed an interaction system and conducted ergonomic experiments and subjective evaluations. Results show that for hand-eye dual-channel systems, the “eye control lock-hand control trigger” strategy ensures high interaction efficiency and usability, with interface layout having no significant impact. This study enhances dualchannel interaction systems’ efficiency and usability, promoting broader application of eye-control interactions.
