Abstract: Embodiments relate to determining characteristics of a display panel by using capturing images through multiple filters where the multiple filters include at least two filters that collectively enable replicating of a color matching function. At least two filters of the multiple filters have transmission profiles that correspond to the same color matching function (x color matching function) in different wavelength ranges. Image capturing devices capture the display panel through respective filters. The captured images are processed to the display characteristics of pixels or regions of the display panel.

Abstract: A virtual reality (VR) console receives slow calibration data from an imaging device and fast calibration data from an inertial measurement unit on a VR headset including a front and a rear rigid body. The slow calibration data includes an image where only the locators on the rear rigid body are visible. An observed position is determined from the slow calibration data and a predicted position is determined from the fast calibration data. If a difference between the observed position and the predicted position is greater than a threshold value, the predicted position is adjusted by a temporary offset until the difference is less than the threshold value. The temporary offset is removed by re-calibrating the rear rigid body to the front rigid body once locators on both the front and rear rigid body are visible in an image in the slow calibration data.

Abstract: A method for detecting a user's hand gestures with a handheld controller. The method includes monitoring a first sensor and a second sensor. Each sensor is capable of sensing the presence of the user's thumb. The method further includes sensing the presence of the thumb on the first sensor and then sensing when the thumb is no longer present on the first sensor. A time period is monitored beginning when the thumb is no longer present on the first sensor and ending when the presence of the thumb is sensed on one of the first sensor and the second sensor. Once the time period exceeds a threshold time value, a thumbs-up gesture is registered.

Abstract: A liquid crystal display (LCD) is configured for use in a head mounted display (HMD) to increase the brightness and improve power consumption of the LCD by recycling light. The LCD includes a color filter (CF) substrate, a thin film transistor (TFT) substrate, and a backlight unit (BLU). The CF substrate is closer to the BLU than the TFT substrate.

The TFT substrate includes TFTs to drive the pixels and a second reflective layer covering TFTs to reflect light away from the TFTs.

Abstract: Disclosed is a system and method for tracking a user's eye using structured light. The structured light system is calibrated by training a model of surface of the user's eye. A structured light emitter projects a structured light pattern (e.g., infrared structured light) onto a portion of the surface of the eye. From the viewpoint of a camera, the illumination pattern appears distorted. Based on the distortion of the illumination pattern in the captured image, the eye tracking system can determine the shape of the portion of the user's eye that the structured light is incident upon. By comparing the determined shape of the portion of the user's eye to the model, the orientation of the eye may be determined. The eye tracking system or elements thereof may be part of a head-mounted display, e.g., as part of a virtual reality system.

Abstract: An electronic display comprises a backlight unit and a liquid crystal (LC) layer, where the backlight combines and directs light from a plurality of light sources towards the LC layer, which controls an amount of light to be displayed. The LC layer is controlled by a plurality of thin-film transistors (TFT) disposed on a TFT layer. To prevent light from the backlight from being absorbed by the TFTs, a dielectric mirror is disposed between the transistors and the backlight unit to reflect light from the backlight unit that is projectors towards the transistors back towards the backlight unit. Hence, light can be recycled and travel through an aperture between the dielectric mirrors, thereby improving luminance.

Abstract: A headset (e.g., VR headset or AR headset) displays a three-dimensional (3D) virtual scene and includes a distance element to dynamically adjust a distance between an optics block and an electronic display included in the headset based on a location in the virtual scene where the user is looking. The headset tracks the user's eyes to approximate gaze lines and determines a plane of focus for a frame of the virtual scene as the intersection of the gaze lines. The distance element adjusts a distance between an optics block and an electronic display so that the optics block is focused at the plane of focus, which keeps the user's eyes in a zone of comfort as vergence and accommodation change.

Abstract: A position tracking system includes an array of detection pixels coupled to a head-mounted display (HMD) configured to capture light signals reflected from an environment surrounding the HMD. The position tracking system maintains, in a database, signal data related to a plurality of positions of the HMD. The position tracking system determines signal data related to a position of the HMD, based on the light signals captured during a time instant of the position of the HMD. The position tracking system matches the determined signal data to the maintained signal data, determines a present position of the HMD based on the matching, updates position data of the HMD with the determined position, and provides the updated position data of the HMD.
