A virtual mouse is a software application that allows users to control the computer cursor without using a physical mouse. Instead, it utilizes computer vision techniques to track the user's hand movements or gestures through a camera and translates those movements into cursor actions on the screen. OpenCV (Open Source Computer Vision Library) is a widely used open-source computer vision and machine learning software library that provides tools to develop such applications. Using OpenCV, developers can create a virtual mouse system that detects hand or gesture movements, tracks them in real-time, and converts these movements into corresponding cursor movements and clicks on the screen. Virtual Mouse is a software that allows users to give inputs of a mouse to the system without using the actual mouse. To the extreme, it can also be called hardware as it uses an ordinary camera. A virtual muse can usually be operated with multiple input devices, which may include an actual mouse or computer keyboard. The virtual mouse uses a web camera with the help of different image processing techniques. Using figures detection methods for instant Camera access and a user-friendly interface makes it more easily accessible. The system is used to implement a motion-tracking mouse, a physical mouse that saves time and also reduces effort. The hand movements of a user are mapped into mouse inputs. A web camera is set to take images continuously. Most laptops today are equipped with webcams, which have recently been used in security applications utilizing face recognition. To harness the full potential of a webcam, it can be used for vision-based CC which would effectively eliminate the need for a computer mouse or mouse pad.
