An optical sensor system that uses focused (not collimated) light optics and produces effective tracking on a variety of surfaces while having looser manufacturing and/or operational tolerances than prior focused optics systems. Embodiments provide an optical sensor system for a mouse moveable on a surface. An LED and a light sensor are coupled to a substrate. An illumination lens directs light at a first angle to the surface, with the light focused on a focal point below the surface. An imaging lens focuses light reflected at an angle generally equal to the first angle on the light sensor. The focal point is sufficiently below the surface so that that the diameter of a produced spot of light on the surface is more than 40% larger than a field of view (FOV) of the light sensor, and less than 400% larger than the FOV of the light sensor.

A light emitting user input device can include a touch sensitive portion configured to accept user input (e.g., from a user's thumb) and a light emitting portion configured to output a light pattern. The light pattern can be used to assist the user in interacting with the user input device. Examples include emulating a multi-degree-of-freedom controller, indicating scrolling or swiping actions, indicating presence of objects nearby the device, indicating receipt of notifications, assisting pairing the user input device with another device, or assisting calibrating the user input device. The light emitting user input device can be used to provide user input to a wearable device, such as, e.g., a head mounted display device.

A wireless position tracking device, a display system, and a wearable device are provided. The wireless position tracking device includes a rigid body, point light sources, a motion sensor, and a wireless transmission module. The rigid body has an inner concave surface, a head, a connecting portion, and a tail. The connecting portion connects the head and tail. The point light sources are fixed to positions outside the inner concave surface. The motion sensor locates in the rigid body for sensing a motion thereof and generating motion information. The wireless transmission module locates in the rigid body and electrically connects the motion sensor for wirelessly transmitting the motion information to the head-mounted device. An image capturing module of the head-mounted device captures a pattern formed by the point light sources. The head-mounted device calculates a relative position of the wireless position tracking device according to the pattern and motion information.

An optical sensor module includes an interferometric sensor and a set of one or more optical elements. The interferometric sensor includes a coherent light source and at least one detector configured to generate an interferometric signal. The set of one or more optical elements is configured to simultaneously direct a first portion of light emitted by the coherent light source toward a first focus area within a first depth of focus; direct a second portion of the light emitted by the coherent light source toward a second focus area within a second depth of focus; and direct portions of the emitted light that are returned from one or more objects within the first depth of focus or the second depth of focus toward the interferometric sensor.

An electronic pen includes a light source configured to emit irradiation light, a rotating body configured to rotate and to reflect the irradiation light emitted from the light source, a first detection member configured to receive the irradiation light reflected by the rotating body, and a first diffraction element provided at an optical path from the light source to the first detection member and configured to diffract the irradiation light.

At a first time point, a first light capturing device at a first spatial location in a three-dimensional (3D) space captures first light rays from light sources located at designated spatial locations on a viewer device in the 3D space. At the first time point, a second light capturing device at a second spatial location in the 3D space captures second light rays from the light sources located at the designated spatial locations on the viewer device in the 3D space. Based on the first light rays captured by the first light capturing device and the second light rays captured by the second light capturing device, at least one of a spatial position and a spatial direction, at the first time point, of the viewer device is determined.

The embodiments of the disclosure relate to an image acquisition method, a handle device, a head-mounted device and a head-mounted system. The handle device comprises a shell and a control module arranged in the shell. A switch control end of an infrared circuit is connected with the control module, and infrared light beads of the infrared circuit penetrate outwards through the shell; and a switch control end of a visible light circuit is connected with the control module, and visible light strips of the visible light circuit penetrate outwards through the shell. Through visible light and infrared light set on the handle, the position of the handle device can be judged, and the tracking accuracy is extremely high.

A head-worn computer includes a camera system positioned to capture a surrounding environment in front of a user, a processor that identifies a position of a plurality of light emitters mounted on a hand-held controller from images captured by the camera system and tracks the position of the plurality of light emitters as the hand-held controller moves in the surrounding environment and interprets the tracked position as positional changes of the hand-held controller. The processor uses the position of the plurality of light emitters as markers in three dimensional space, the markers used as an anchor for virtual content presented in a see-through display of the head-worn computer.
