2-4 Comparison of Real-time Smoothing Filters for Spatial Operating Interfaces

Abstract

Recently research of recognizing real-time motion of a finger in the air to perform an input operation has been carried out. However, because of hand trembling, disturbance and sensor resolution, stable operation is difficult. Therefore, it is necessary to realize stable operation by smoothing the trajectory of the finger in real time. In this study, giving a priority to the smoothness of the trajectory and the delay amount, we compared several smoothing filters to find the best filter to solve the problem.
