This paper explores the innovative realm of touch-free text entry, specifically focusing on the paradigm shift brought about by fingertip-based air writing. Traditional input methods often require physical contact, limiting user interaction in various scenarios. In response to this challenge, our research delves into the development and evaluation of a novel system that enables users to input text seamlessly through gestures in the air using their fingertips. The objective of this study is to assess the feasibility, accuracy, and user experience of fingertip-based air writing as a touch-free text entry method. We present a detailed description of the underlying technology, including the algorithms and sensors employed in capturing and interpreting fingertip movements. Our methodology involves user trials with diverse participants, evaluating the system’s performance across different contexts and linguistic patterns. Results indicate promising potential for fingertip-based air writing as an intuitive and efficient touch-free text entry method. Participants demonstrated quick adaptability to the system, achieving comparable typing speeds to conventional methods. The implications of this research extend beyond conventional touch-based interfaces, offering a transformative approach to human-computer interaction. In conclusion, this paper contributes to the ongoing evolution of input methods by introducing and validating fingertip-based air writing. The findings underscore the viability of touch-free text entry, paving the way for future developments in user-friendly interfaces and expanding the horizons of interactive technology.
