Abstract: Fiducial patterns that produce 2D Barker code-like diffraction patterns at a camera sensor are etched or otherwise provided on a cover glass in front of a camera. 2D Barker code kernels, when cross-correlated with the diffraction patterns captured in images by the camera, provide sharp cross-correlation peaks. Misalignment of the cover glass with respect to the camera can be derived by detecting shifts in the location of the detected peaks with respect to calibrated locations. Devices that include multiple cameras behind a cover glass with one or more fiducials on the cover glass in front of each camera are also described. The diffraction patterns caused by the fiducials at the various cameras may be analyzed to detect movement or distortion of the cover glass in multiple degrees of freedom.

Abstract: Various implementations disclosed herein include devices, systems, and methods that initiate an action based on a detected gaze direction oriented towards a target area (e.g., a hot corner/zone). For example, an example process may include producing a reflection by directing light towards an eye using an illuminator, receiving sensor data from a sensor, wherein a direction of sensing by the sensor (e.g., the optical axis of the camera) and a direction from the eye to a target area are approximately aligned, determining a reflective property (e.g., a spectral property) of the reflection based on the sensor data, detecting that a gaze direction of the eye is approximately oriented towards the target area (e.g., a hot zone/spot) based on the reflective property, and initiating an action based on detecting that the gaze direction is approximately oriented towards the target area.

Abstract: Methods and systems for relative inertial measurement may include a user device comprising an inertial measurement device and/or a camera. A second inertial measurement device may be configured to move with a reference frame. One or more processors may receive inertial measurements from the first and second inertial measurement devices and determine movement of the user device relative to the reference frame by comparing the received inertial measurements. Additionally reference objects in a view of a camera may be used to calibrate the determined motion of the user device within the reference frame.

Abstract: Methods and apparatus for specular surface mapping in which a camera detects reflections of a light source from a specular surface. The detected light sources may be projected onto a celestial sphere as virtual point sources. True positive observations should be tightly clustered on the celestial sphere; thus, false positives may be identified and removed. Specular surface information may then be determined from clusters of the virtual point sources on the celestial sphere. The clusters of virtual point sources on the celestial sphere may be identified and used to identify a surface as a specular surface. The clusters may also be used to extract other information regarding the specular surface, including but not limited to distance to and extent of the specular surface.

Abstract: Lighting may be provided using light sources such as lighting systems with arrays of light-emitting diodes. A lighting system may be integrated into a seat, a door panel, a dashboard, or other interior portions of a system such as a vehicle. The interior portions of the vehicle may be illuminated using lighting systems to provide ambient light, to provide custom surface textures and other decorative patterns, to provide icons, text, and other information, and to provide custom gauges and other illuminated regions. Illuminated regions may overlap sensors such as capacitive touch sensors, force sensors, and other sensors. The light-emitting diodes in a lighting system may supply light that passes through openings in a cover layer. The layer may be formed from fabric, leather, or other materials. Lens structures may guide light through the openings.

Abstract: Object detection may include transmitting, by a first device, a first pulse into an environment using a wide field configuration of an ultrasonic sensor array, detecting a presence of an object in the environment based on a detected echo based on the first pulse. In response to detecting the presence of the object, a targeted configuration of the ultrasonic sensor array is determined, and a second pulse is transmitted into the environment based on the second pulse, wherein a characteristic of the object is determined based on a detected echo from the second pulse.

Abstract: A vehicle may have optical structures such as windows and mirrors that have the potential to allow glare from external objects to shine into the eyes of a driver or other vehicle occupant. A control circuit may gather information on where the eyes of the driver are located using a camera mounted in the vehicle and may gather information on where the sun or other source of glare are located outside of the vehicle. Based on this information, the control circuit may direct a light modulator on a window or mirror to selectively darken an area that prevents the glare from reaching the eyes of the driver. The light modulator may have a photochromic layer that is adjusted by shining light onto the photochromic layer, may be a liquid crystal modulator, an electrochromic modulator, or other light modulator layer.

Abstract: One exemplary implementation involves performing operations at an electronic device with one or more processors and a computer-readable storage medium. The device establishes a wireless communication link with a host device. The device receives, from the host device, a left eye frame and a right eye frame via a sequence of interleaved left eye frame transmissions and right eye frame transmissions. The device loads the left eye frame into a left eye display device and loads the right eye frame into a right eye display device on the electronic device, where the loading includes sequentially loading left eye frame portions and right eye frame portions as the sequence of interleaved left eye frame transmissions and right eye frame transmissions is received. The device then concurrently displays the left eye frame and the right eye frame at the electronic device. The device switches data transmissions schemes according to wireless communication link quality and eye gaze tracking.
