The gesture recognition technology has been known as a way for computers to understand human body language. It’s a basic topic in computer science and language technology with the main goal of interpreting human gestures via mathematical algorithms.
Speaking about gestures, it can be originated from any bodily motion, but it’s mostly concentrate on the face or hand. The major focuses in the gesture recognition include emotion recognition from the face and hand gesture recognition.
Many researchers have been using cameras and computer vision algorithms to interpret sign language. Honestly, the gesture recognition technology allows the users to interface with the machine and interact naturally without need any additional mechanical devices.
It’s possible to point a finger at the computer screen, by using the gesture recognition concept, so that the cursor will move accordingly.
Today’s project is very easy, as all you need to do here is to utilize a microphone and place it in a stethoscope, which is used to recognize various gestures when a fingernail is being dragged over a surface!
The microphone has the ability listening to the sound of scratching that is transmitted through the surface material. The gesture recognition program works perfectly, by analyzing the number of peaks and the width of these peaks for the different gestures.
