Abstract or Table of Contents
In this paper, we present a novel contactless gesture recognition system using proximity sensors. A set of infrared signal feature extraction methods and a decision-tree-based gesture classifier are proposed. The system allows a user to interact with mobile devices using intuitive gestures, without touching the screen or wearing/holding any additional device. Evaluation results show that the system is low-power, and able to recognize 3D gestures with over 98% precision in real time.
