Correlation-based Contactless Hand-Gesture Detection for Capacitive Sensing

This article considers gesture-based algorithms that allow us to control various devices with movements of our hands. Correlation coefficient is used to determine the sign of the derivative of the signal from the sensor to detect flick gesture (hovering over an area where sensors are located) and click gesture (approaching and distancing this area). The results of numerical experiments are presented hereinafter, which confirms the robustness of the proposed gesture identification algorithm for controlling various devices.
