The Role of Gesture-Based Interaction in Improving User Satisfaction for Touchless Interfaces

Abstract

Gesture-based interaction has emerged as a promising technology for enhancing user satisfaction in touchless interfaces, offering more natural, intuitive, and efficient ways of interacting with digital systems. This study explores the impact of gesture-based interfaces on user satisfaction by examining various applications across industries such as healthcare, gaming, smart homes, and public displays. As the demand for hygienic, contact-free technologies increases, particularly in the wake of global health concerns, gesture-based systems provide an innovative solution that reduces reliance on physical contact while maintaining high usability. The research investigates how different types of gestures—such as swipe, tap, and point—affect user experience in terms of accuracy, ease of use, and emotional engagement. Through a mixed-method approach combining quantitative surveys and usability testing, the study evaluates user satisfaction levels, analyzing factors such as learning curve, task completion time, and the sense of control over the interface. Results indicate that gesture-based interaction significantly enhances user satisfaction by making interfaces more engaging and accessible, particularly for users with mobility impairments or those interacting with public systems where physical contact is minimized. The findings suggest that, while there are challenges related to gesture recognition accuracy and user fatigue, the potential benefits in terms of efficiency, hygiene, and accessibility make gesture-based interaction a valuable component of future interface design. This research offers insights into optimizing gesture-based systems to improve user satisfaction, recommending best practices for interface designers and developers working to implement effective touchless solutions.
