Abstract: Apparatus for generating a dynamic structured light pattern for optical tracking in three-dimensional space, comprises an array of lasers, such as a VCSEL laser array, to project light in a pattern into a three-dimensional space; and an optical element or elements arranged in cells. The cells are aligned with subsets of the laser array, and each cell individually applies a modulation, in particular an intensity modulation, to light from the laser or lasers of the subset, to provide a distinguishable and separately controllable part of the dynamic structured light pattern. A method of generating a structured light pattern is disclosed, in which light is provided from an array of lasers, and light is individually projected from subsets of the array of lasers to provide differentiated parts of the structured light pattern.

Abstract: A method, a system, and a device for navigating in a virtual reality scene, using body parts gesturing and posturing are provided herein. The method may include: projecting a synthetic 3D scene, into both eyes of a user, via a near eye display, so as to provide a virtual reality view to the user; identifying at least one gesture or posture carried out by at least one body part of said user; measuring at least one metric of a vector associated with the detected gesture or posture; applying a movement or action of said user in virtual reality environment, based on the measured metrics; and modifying the virtual reality view so as to reflect the movement or action of said user in the virtual reality environment.

Abstract: A tracking system generates a structured light pattern in a local area. The system includes an array of lasers that generate light. The array of lasers includes a plurality of lasers and an optical element. The plurality of lasers are grouped into at least two subsets of lasers, and each of the at least two subsets of lasers is independently switchable. The optical element includes a plurality of cells that are each aligned with a respective subset of the array of lasers. Each cell receives light from a corresponding laser of the array of lasers, and each cell individually applies a modulation to the received light passing through the cell to form a corresponding portion of the structured light pattern that is projected onto a local area.
