Systems, devices, and techniques related to projecting dynamic feature patterns onto a scene for use in stereoscopic imaging are discussed. Such techniques may include implementing a dynamic transmissive element in an optical path between a projector and the scene to modify a static pattern emitted from the projector to illuminate the scene with a dynamic pattern.

Projector for active stereo depth sensors

A light pattern projector with a pattern mask to spatially modulate an intensity of a wideband illumination source, such as an LED, and a projector lens to reimage the spatially modulated emission onto regions of a scene that is to be captured with an image sensor. The projector lens may comprise a microlens array (MLA) including a first lenslet to reimage the spatially modulated emission onto a first portion of a scene, and a second lenslet to reimage the spatially modulated emission onto a first portion of a scene. The MLA may have a fly's eye architecture with convex curvature over a diameter of the projector lens in addition to the lenslet curvature. The pattern mask may be an amplitude mask comprising a mask pattern of high and low amplitude transmittance regions. In the alternative, the pattern mask may be a phase mask, such as a refractive or diffractive mask.

LED pattern projector for 3D camera platforms

In embodiments, apparatuses, methods and storage media for human-computer interaction are described. In embodiments, an apparatus may include one or more light sources and a camera. Through capture of images by the camera, the computing device may detect positions of objects of a user, within a three-dimensional (3-D) interaction region within which to track positions of the objects of the user. The apparatus may utilize multiple light sources, which may be disposed at different distances to the display and may illuminate the objects in a direction other than the image capture direction. The apparatus may selectively illuminate individual light sources to facilitate detection of the objects in the direction toward the display. The camera may also capture images in synchronization with the selective illumination. Other embodiments may be described and claimed.

Object position determination

Apparatus, computer-readable storage medium, and method associated with human computer interaction. In embodiments, a computing device may include a plurality of sensors, including a plurality of light sources and a camera, to create a three dimensional (3-D) interaction region within which to track individual finger positions of a user of the computing device. The light sources and the camera may be complementarily disposed for the camera to capture the finger or hand positions. The computing device may further include a 3-D interaction module configured to analyze the individual finger positions within the 3-D interaction region, the individual finger movements captured by the camera, to detect a gesture based on a result of the analysis, and to execute a user control action corresponding to the gesture detected. Other embodiments may be described and/or claimed.

Gesture based human computer interaction

According to one embodiment, a system includes a handheld device having a pixelated sensor, an optical filter for passing a predetermined frequency band of radiation to the sensor and a transmitter, an electronic equipment having a display, and at least two spaced-apart markers, where each of which are positioned proximate to the display. The markers provide radiation at the frequency band passed by the optical filter. The handheld device includes a processor coupled to receive image data of the markers from the sensor for computing coordinate data from the image data. The coordinate data requires less data than the image data. The processor is coupled to the transmitter to transmit the coordinate data to the electronic equipment. Other methods and apparatuses are also described.

Methods and apparatuses for a free-space multi-dimensional absolute pointer using a projection marker system are described herein. In one embodiment, a presentation system includes, but is not limited to, a projection-based marker apparatus to project one or more optical spots on a display surface for displaying machine generated content capable of being manipulated via a cursor of a pointing device, a handheld device to wirelessly capture the projected optical spots from the display surface, and a control unit communicatively coupled to the projection-based marker apparatus and the handheld device to determine coordinates of the cursor based on characteristics of the captured light spots. Other methods and apparatuses are also described.

Free-space multi-dimensional absolute pointer using a projection marker system

A method is described that involves identifying one or more images of respective one or more fixed markers. Each marker is positioned on or proximate to a display. The images appear on a pixilated sensor within a handheld device. The method also involves determining a location on, or proximate to, the display where the handheld device was pointed during the identifying. The method also involves sending from the handheld device information derived from the identifying of the one or more images of respective one or more fixed markers. The method also involves triggering action taken by electronic equipment circuitry in response to the handheld device's sending of a signal to indicate the action is desired.

Handheld vision based absolute pointing system

A tunable filter may be utilized to successively tune to different wavelengths. As each wavelength of the wavelength division multiplexed signal is extracted, it may be successively power monitored. Thus, power monitoring may done without requiring separate power monitors for each channel. This results in considerable advantages in some embodiments, including reduced size, reduced complexities in fabrication, and reduced yield issues in some embodiments.

A method is described that involves detecting one or more images appearing on a pixilated sensor of respective one or more fixed markers. The pixilated sensor is within a handheld device. For each of the images, determining its location on the sensor with the handheld device's electronic circuitry. Translating the images' determined locations into a pointed to location on a display, or proximate to said display, wherein the handheld device transmits information derived from the determining.

Electronic equipment for handheld vision based absolute pointing system

A planar light wave circuit may be formed with a pair of waveguides arranged in close proximity to one another. At least one of the waveguides may be segmented. Through segmentation, the average mode-field diameter may be adjusted. Controlling the average mode-field diameter enables precise control over the coupling characteristics.

Segmented waveguide coupler

Multiple Bragg gratings are fabricated in a single planar lightwave circuit platform. The gratings have nominally identical grating spacing but different center wavelengths, which are produced using controlled photolithographic processes and/or controlled doping to control the effective refractive index of the gratings. The gratings may be spaced closer together than the height of the UV light pattern used to write the gratings.
