Hand Gesture Recognition Based Calculator

Gesture Recognition pertains to the process which includes understanding and interpreting meaningful movements of the body parts such as arms, face, hands or head. It allows us to talk to the machines and use them with means other than electrical devices. The technique also provides us an innovative, efficient and user-friendly way of interaction to which we are, sort of, more familiar. To convey information, the use of gestures can be quite useful in communication. This way gesture recognition plays a crucial role in our daily life. Gesture Recognition has uncountable uses, such as sign-language, machinery, robotics, computer games, virtual reality and much more. This proves that gesture recognition can be the key research area for Scientists. Hand gestures are of 2 types, static and dynamic. The three main phases of the technique on which the whole approach works are object detection, object tracking and recognizing the gesture. We developed a fast and simple calculator based on hand gesture recognition system. It uses gestures as inputs and performs calculations according to these gestures. The objective of the paper is to make the interaction between humans and computers as natural as the interaction between humans.
