Integrating Low-Cost Eye-Trackers to Enhance Design Education: A Case Study in University Course

The integration of technology in the classroom should be based on low-cost devices and affordable solutions, allowing educators to fully explore their potential benefits. Product design education is undergoing a profound transformation in response to these changes. The aim of this study is to demonstrate the integration of low-cost eye-tracking (ET) technology within a product design process. This research presents a practical case involving a group of design students who incorporated an ET device, as well as an alternative tracking method (AT) that simulates eye movement, to develop a product following a custom design methodology. The impact of both the methodology and the low-cost technology was evaluated through surveys administered to forty-seven students. The evaluation focused primarily on "utility, novelty, and relevance" as key aspects. The results showed consistently high approval ratings for both technologies. However, ET received significantly higher and more favorable evaluations. A detailed analysis of the evaluated elements indicated a strong preference for ET in terms of utility, novelty, and relevance. Furthermore, a correlational analysis revealed that students associated the integration of low-cost technology with usefulness and a positive experience. The findings of this case study highlight that low-cost devices and innovative methodologies are effective tools for enhancing teaching and learning experiences for students, educators, and researchers.
