Title
(EN) HEAD MOUNTED DEVICE FOR VIRTUAL OR AUGMENTED REALITY COMBINING RELIABLE GESTURE RECOGNITION WITH MOTION TRACKING ALGORITHM
Abstract
(EN)

A head mounted device for virtual or augmented reality including:

    • a display element configured to display content;
    • at least one infrared camera module configured to operate at a predetermined bandwidth;
    • an illuminator having a wavelength of operation inside the bandwidth of the infrared camera, and having a field of view before the camera module; and
    • a control unit implementing a six degrees of freedom (6DoF) algorithm to determine 6DoF poses from data including image data of the camera module, and implementing a gesture tracking algorithm.
