Review On An Iot Based Gesture Recognition Using Ultrasonic Sensor.
Gesture is a symbol of physical behavior or emotional expression. Gestures can originate from any bodily motion or state but commonly originate from the face or hand. Gesture recognition is very significant for human-computer interaction. It is a language technologyin computer science which interpreting human gestures via mathematical algorithms.Internet of Things or IoT is nothing but an evolved version of Internet, which includes sensors, consumer electronic devices and other embedded systems connected to it besides computers, smart phones and tablets to collect and exchange data with one another.With the rapid development of Internet of Things, hand gesture recognition has drawn wide attention in the eld of ubiquitous computing because it provides us with simple and natural human-computer interaction mode.The aim of this paper is to survey a system that detects the hand gesture motions using ultrasonic sensor based on IOT.
