Hand Gesture Remote is a computer vision based project implemented using opencv , python,raspberry pi. The camera feed will be processed at rpi and recognize the hand gestures. Then detected gesture will map to predefined GPIO signal of the rpi. Here is a demo of video https://youtu.be/U8X_tLIOGAc
Hand gesture based remote is an embedded device which will convert hand gestures to infrared signals (IR). It can recognize certain no of hand gestures of user and do some operations according to them.
Example - If we integrate with TV, we can increase/decrease volume, change the TV channels and etc.
We can integrate this system to control any kind of device/actuators.
The overall system has 4 main components
Here is the overview of overall system
1.1 Camera Unit
This unit will capture the video stream of the environment and send it to the video processing unit. Simply this unit contains camera and illumination system to capture video stream. This unit implemened using raspberry pi3 camera front illumination system.
1.2 Video Processing Unit
This unit will be done the main operation of the system. The received video data will be processed at this unit which was implemented using raspberry pi 3 development board. The image processing was implemented using OpenCV and python. The received video will process and detect hand gestures. Then detected hand gestures will be converted to predefined GPIO signal.
Here is a video demontrantion of the computer vison part

1.3 IR signal Unit
This unit contains two components.
1.3.1 IR signal Generator
According to GPIO signal, this component will generate infrared signals (IR)
1.3.2 IR signal Receiver
This component will capture IR signals generated by the IR generator and control the target actuators.
Example - If we want to control a fan, we have to integrate this component with the switching circuit of the fan
1.4 Power Unit
The power unit will help to run the whole system. This will power the raspberry pi and IR signal unit. We use 5v/2A power supply in this system.
