Precision multi-view display
A precision multi-view (MV) display system can accurately and simultaneously display different content to different viewers over a wide field of view. The MV display system may include features that enable individual MV display devices to be easily and efficiently tiled to form a larger MV display. A graphical interface enables a user to graphically specify viewing zones and associate content that will be visible in those zones in a simple manner. A calibration procedure enables the specification of content at precise viewing locations.
Dynamic illumination for eye-tracking
An apparatus includes a controller coupled to a stereoscopic image viewer. The stereoscopic image viewer includes a viewing lens, an image capture unit, and a plurality of light sources. The image capture unit is configured to capture image frames. The controller receives the captured image frames. The controller is configured to switch light output from one of the plurality of light sources to another one of the plurality of light sources if a corneal reflection in a captured image frame intersects a fixed reflection in the captured image frame.

Methods for camera movement compensation
A method, system, apparatus, and/or device for adjusting or removing frames in a set of frames. The method, system, apparatus, and/or device may include: associating a first frame of a set of frames with motion data that is captured approximately contemporaneously with the first frame; when a sampling rate of the motion data is greater than a frame rate of the set of frames, aggregating a first sample of the motion data captured at the first frame and a second sample of the motion data captured between the first frame and a second frame of the set of frames to obtain a movement value; when the movement value does not exceed a first threshold value, accepting the first frame from the set of frames; and when the movement value exceeds the first threshold value, rejecting the first frame from the set of frames.
Beamforming vacuum cell
Beamformers are formed (e.g., carved) from a stack of transparent sheets. A rear face of each sheet has a reflective coating. The reflectivities of the coatings vary monotonically with sheet position within the stack. The sheets are tilted relative to the intended direction of an input beam and then bonded to form the stack. The carving can include dicing the stack to yield stacklets, and polishing the stacklets to form beamformers. Each beamformer is thus a stack of beamsplitters, including a front beamsplitter in the form of a triangular or trapezoidal prism, and one or more beamsplitters in the form of rhomboid prisms. In use, a beamformer forms an output beam from an input beam. More specifically, the beamformer splits an input beam into plural output beam components that collectively constitute an output beam that differs in cross section from the input beam.
