HEAD TRACKING FOR VIRTUAL REALITY DISPLAYS

摘要

A tracking device for determining position of at least one user relative to a video display has a wearable structure configured to be mounted on a human such a as a headset, eyeglasses or arm bands. The structure has two clusters of light emitting components which are spaced apart from one another. The LEDs in each cluster can emit different wavelengths of lines and be activated in sequences to identify not only the position of the user but also to distinguish one user from another user.
