System Sound Control Using Gesticulations

Artificial intelligence is a field of computer science dedicated to solving reasonable problems mostly associated with human intelligence such as pattern recognition and problem solving. This chapter proposes a project controlling the sound (increasing or decreasing the volume) of a computer or a laptop using real-time hand gestures as input through a web camera, which is not necessarily a high-resolution camera, which makes it a cost-efficient project. Making use of gestures is one of the leading aspects contributing toward artificial intelligence and development in the field of technology. This project is implemented using the Python programming language. Here, we make use of the OpenCV library of Python to read the gestures from the user through the web camera. OpenCV is a widely used tool for processing images. To perform hand recognition and hand processing, we make use of the Hand Landmark Model of the MediaPipe Hands library of Python. To control the audio or volume of the system, we make use of the PyCaw Library of Python. Using these Python libraries makes it easy to implement complex projects as most of the required operations or functionalities can be done using a pre-defined function in the particular library.
