The "head-operated mouse" is an alternative mouse designed for people who are unable to use their hands. It detects the user's head movements with different techniques (such as facial recognition and infrared or ultrasound devices) and it is transmited as a movement of the pointer in the screen. The "click" and other functions of the mouse buttons are usually emulated with a program which is usually included with the product, or using a virtual mouse (for instance, Point-N-Click for Windows). Furthermore, if the user has some type of mobility, an additional pusher can be used for the click function.
