Abstract: A volume holographic film (such as a photopolymer) that is pre-recorded with patterns subsequently is used to encode LED or low-power laser light reflections from an eye into a binary pattern that can be read at very high speeds by a relatively simple complementary metal-oxide-semiconductor (CMOS) sensor that may be similar to a high framerate, low resolution mouse sensor. The low-resolution mono images from the film are translated into eye poses using, for instance, a look up table that correlates binary patterns to X, Y positions or using a pre-trained convolutional neural network to robustly interpret many variations of the binary patterns for conversion to X, Y positions.

Abstract: A projection system projects images onto a projection surface in, for example, a computer game head-mounted display (HMD). The light is projected through a spatial light modulator that is combined with a Freeform Fourier Lens that is a combination of a Fresnel lens, an X-phase grating, a Y-phase grating, and a radial grating. The freeform lens causes the gradual shrinking of portions of the laser-projected image, decreasing the perceived pixel pitch in at least one foveal area on the projection surface compared to a non-modulated laser image. The center positions of the Fresnel lens and radial grating can be changed in the X and Y axes, moving the condensed foveal areas in accordance with eye tracking of the user. In effect, the system projects a Foveated image that contains variable pixel pitch such that a user perceives a higher visual acuity in his gaze direction.

Abstract: To derive three dimensional (3D) position and orientation of a 3-axis (or more) magnetometer/accelerometer device (such as may be implemented in VR or AR headset or computer game controller) without line of sight constraints, a spinning magnetic field is used to discriminate and remove the external (Earth's) magnetic field from the spinning magnetic field. This reduces the problem to finding the distance to the source of the magnetic field using a calibration table (or formula), finding two angles describing the deviation of the magnetic sensor from the axis of rotation of the spinning magnetic field and the phase around this axis, and from these values deriving the orientation of the sensor.

Abstract: Generally, techniques related to an optical computer system and use thereof are described. In an example, an optical computer system includes a multi-purpose optical device, an imager, and an image sensor. The multi-purpose optical device is configured for different purposes, such as for data storage and for compute operations. The configuration utilizes diffractive optical layers that include different diffraction elements. The imager displays an image to the multi-purpose optical device. The image encodes command-related data depending on the purpose to be invoked, such a data location for a data read or input for a compute command. Light of the image travels to the multi-purpose device and is diffracted from the diffractive optical layers. The diffracted light is detected by the image sensor that converts it into an output.

Abstract: Stereoscopic viewing systems may be adjusted for a user's inter-pupillary distance (IPD). An inter-pupillary distance (IPD) value is determined from a signal from a position sensitive device coupled to two moveable sighting fixtures mounted to a head mounted display (HMD) having two fixed optics configured for a specific inter-pupillary distance. The position sensitive device is configured to produce a signal that corresponds to a distance between the two sighting fixtures. The images are warped with a processor to optimize display of the images with the two fixed optics for the determined IPD value.

Abstract: A projection system projects images onto a projection surface in, for example, a computer game head-mounted display (HMD). The light is projected through a spatial light modulator that contains a phase-only image of a Freeform Fourier Lens that is a combination of a Fresnel lens, an X-phase grating, a Y-phase grating, and a radial grating. The freeform lens is a condensing freeform lens that causes the gradual shrinking of portions of the laser-projected image, decreasing the perceived pixel pitch in at least one foveal area on the projection surface compared to a non-modulated laser image. The center positions of the Fresnel lens and radial grating can be changed in the X and Y axes, moving the condensed foveal areas in accordance with eye tracking of the user. In effect, the system projects a Foveated image that contains variable pixel pitch such that a user perceives a higher visual acuity in his gaze direction to the projected surface.

Abstract: Stereoscopic viewing systems may be adjusted for a user's inter-pupillary distance (IPD). Software-generated calibration images may be presented on a display having two optics. One or more settings for presentation of the calibration image are adjusted. The settings are related to an inter-pupillary distance (IPD) of the user. An input is received from a user when the user perceives the calibration image to be acceptable at a particular value of the one or more settings. An IPD value that corresponds to the particular value of the one or more settings is then determined. The determined IPD value is used in presenting subsequent software-generated images with the stereoscopic display.

Abstract: An emitter laser illuminates multiple reflectors each of which produces a unique robust code, with the laser being sequentially moved between illuminating successive reflectors. The reflectors send light to a holographic film, and the laser poses can be associated with the respective codes. Subsequently, an illuminator such as another laser can illuminate the film, and a sensor positioned near the film records what code is produced, so that the code can be correlated to a laser pose with respect to the film and sensor.
