Head Tracking

An assistive technology input method that translates natural head movements into computer cursor control or other input actions. Head tracking systems use cameras, infrared sensors, or depth sensors to detect head position and orientation, allowing users with limited or no hand function to navigate interfaces, select items, and type using on-screen keyboards. This technology is particularly valuable for people with spinal cord injuries, muscular dystrophy, or other conditions that limit upper-limb mobility while preserving head control.
