Wireless Hand Gesture Recognition for an Automatic Fan Speed Control System: Rule-Based Approach

Wireless communication may be between humans or machines is very much prevailing at these times. One of the most known methods is the use of Bluetooth. Bluetooth is perfect for short-range wireless communication and is a feature that can be found on phones, computers, and other electronic devices. In this study, it aims to create a wireless hand gestured controlled fan. The Bluetooth module is the main component used for transmitting and receiving information. The study used a gyro sensor in order to determine the change in coordinates of the hand in which the speed of the rotation of the fan will be dependent on it. It is connected to a microcontroller, specifically an Arduino in which coded functions have been used. Hand gesture recognition has been done with an overall testing accuracy of 98.61%. Wireless hand gesture fan speed control system has been effective and possible using the coordinates produced by the Bluetooth and gyroscope axis.
