Hand tracking is software that estimates a hand’s position, shape, and finger movement in real time, often using cameras and computer vision. It enables touch-free control in virtual and augmented reality, gesture interfaces, and other interactive systems.
In cyber security, hand tracking is part of a sensor-driven system whose reliability depends on what its sensors can observe. Fingers may be hidden, overlap, or leave the camera’s view, making estimates less certain. In real-world use, poor lighting, camera placement, or calibration can also affect results. Developers can test how systems handle missing or ambiguous data and avoid treating uncertain tracking as reliable input for sensitive actions.
