Hand Gesture Controlled Machines

Abstract

With the discovery of electronics, it has become an essential part of everyone’s life. In the recent times, control of electronic devices such as smartphones, robots and machinery have grabbed the attention of many people. People have started to move towards automation where electrical machines can take decision on its own. However, in some cases a volunteer is required to control the robot/smartphone/machine instead of relying on a piece of code. Hence, the appearing advancement in technology has developed a need for natural user interface very much required. To fulfill this need, we have come up with the idea of Hand Gesture Controlled Machines. Controlling machines via Hand Gesture Recognition will be implemented to improve the interaction between human and machines. The aim of this Hand Glove (consisting of a raspberry pi kit, flex sensors and HC-12) is to sense the movement of the fingers and control the movement of the machine according to it movement wirelessly. The reason to do so is that movement of fingers are natural which compose a gesture, so it does not require any extra effort or learning for the user to interact. The idea behind the project is to develop a device that will control a machine by doing some gestures. For this purpose, flex sensors were mounted at every fingers. The bend in a finger causes a change in its resistance. This signals are detected by the raspberry pi which passes a command to the machine which in turns causes a movement in it. All the processes are done in a controlled environment.
