Optimizing Augmented Reality Displays for Culinary Guidance: Investigating High-Contrast Effects in Human-Machine Interface

As AR technology advances, it is transforming user interaction by providing hands-free, real-time guidance. In culinary settings, AR enhances cooking efficiency, particularly for individuals with limited experience. This study investigates AR text displays in high-contrast environments for synchronous recipe teaching, focusing on novice users. A quantitative study with 20 participants compared two groups: one using AR glasses for real-time recipe guidance and the other using a tablet-based digital recipe. AR users benefited from hands-free guidance, seamlessly following instructions while handling ingredients, whereas tablet users frequently shifted attention between the screen and their cooking. Usability, user experience, and visual strain were assessed using the System Usability Scale (SUS) and Near Point Accommodation (NPA) tests. Results showed that AR significantly improved cooking performance, efficiency, and confidence. The hands-free interface minimized disruptions, and high-contrast text did not induce visual fatigue. These findings highlight AR’s potential in interactive cooking and learning, benefiting both amateur and professional chefs. Integrating AR into culinary education and professional kitchens could enhance training and skill development. Future advancements, including AI-driven personalization and gesture-based controls, could further optimize AR’s role in digital culinary assistance and immersive learning.
