Every day program designers try to make their programs more accessible, so that even people with a discapacity or disablement can use them easily. This qMouse is a good example.
The aim of qMouse is to completely substitute the mouse and keyboard; so disabled people don`t need to use them. It works in the following way: via a webcam it detects all the movements of the face, and depending on each movement it moves the mouse cursor. To click with the mouse, you predetermine a specific facial movement.
Apart from mouse movements, qMouse includes a virtual keyboard so that, via certain gestures, you can write. To work correctly you need to previously install Framework .NET 2.0 or later.
