A comparative analysis between light dependent and ultrasonic method of gesture recognition

摘要

In this paper, two methods of gesture recognition are discussed and a comparison between these methods is carried out. These are light dependent and ultrasonic method of gesture recognition. The light dependent method was developed in an early study, where a control panel detected some predefined gesture commands and a robotic arm was controlled with those commands. In this new study the same gesture commands are used to control the robotic arm. But this time they are determined by both light dependent and ultrasonic method. All the procedure and arrangements are kept unchanged so that a comparative performance test for these two methods can be carried out. Experimental results and cost analysis shows that the light dependent method is more convenient for indoor application of the system. Whereas, for outdoor application, the ultrasonic method is preferable.
