Comparison of Panel and Pie Menus for Mid-Air Interaction in a Photo Booth: Muscle Activity, Performance, and User Experience.

Research on visual menus, specifically panel and pie menus, has gained widespread attention in recent times. However, limited research focuses on the mid-air interaction when comparing these two menu types. This study aimed to conduct a comprehensive comparison between panel and pie menus in the context of cursor-based mid-air interaction within a photo booth setting. The evaluation involved analyzing muscle activities, performance metrics, and user experience to quantify the differences between the two menus across three menu operations. Our results indicated that the pie menu offered notable advantages by reducing muscular loads, achieving shorter task completion times, and delivering an overall more enjoyable user experience, making it a preferable choice for mid-air interaction in photo booth settings. Conversely, the panel menu exhibited superior scores of learnability and demonstrated enhanced accuracy in the switching operation, suggesting that it might be a better choice for complex and precision-demanding tasks.
