Hand Tracking

A technology that detects and tracks the position, orientation, and movements of a user's hands and fingers without requiring physical controllers, typically using cameras and computer vision algorithms. In extended reality, hand tracking enables hands-free interaction through gestures like pinching, grabbing, pointing, and waving. For accessibility, hand tracking is particularly valuable in contexts where users' hands need to remain free for other tasks (such as playing a musical instrument) or for users who cannot operate traditional controllers due to motor disabilities.
