The mouse is one of the best invention of Human-Computer Interaction technology. Nowadays, wireless or bluetooth mouse still uses device and it not free of devices since it uses batteries for power source and Dongles to connect to the personal computer. At emergency situation like wire damaged while in the meeting then the AI virtual mouse system will help. Like this problems can be overcome by using their webcam or a built-in camera for capturing of hand detection using computer vision. based on the hand gestures movement, the computer can be controlled virtually and can perform left click, right click, scrolling functions and computer cursor function without the use of the physical mouse. In the current situation where we are adjusting our living while being in the pandemic, a touchless mouse controller will be useful to eliminate the risk of spreading infection through touch on public service devices. In this project, we have created an AI- based Mouse Controller. It will first detect the hand landmarks, then track and then perform functions. We have also applied smoothing techniques to make it more usable. The virtual mouse will be operated without touching any device or screen. The domain of the project is AI/ML. The programming language used is mainly Python. This system is based on the concept of computer vision
