Head Pointing

Head pointing is an alternative input method that maps head movements to cursor position on a computer screen, enabling hands-free mouse control. The user moves their head to direct the cursor, with the system translating head orientation or position into screen coordinates. Head pointing devices range from electromagnetic trackers and infrared sensors to modern webcam-based solutions that use computer vision to track facial landmarks. This input method is primarily used by individuals with motor disabilities who cannot operate a traditional mouse, and is often combined with speech input or dwell-clicking to provide complete hands-free computer access.
