Abstract: An image displayable at a head-mountable display (HMD) is downsampled to an image pixel representative of the image. The luminance of the image pixel is computed from a color value of the image pixel to determine image brightness. The foveal region of the image is computed from eye-tracking information of the user of the HMD. The foveal region of the image is downsampled to a foveal pixel representative of the foveal region. The luminance of the foveal pixel is computed from a color value of the foveal pixel to determine foveal region brightness.

Abstract: Structured light is projected onto an object, and an image of the object as illuminated by the projected structured light is captured. Reference object points are identified within the captured image, and the structured light projected onto the object is modified based on the identified reference object points. An additional image of the object as illuminated by the modified projected structured light is captured, and additional reference object points are identified within the captured additional image.

Abstract: A computing device receives a notification from a tracking device that the tracking device has entered a gripped state in which a user has securely gripped the tracking device with a hand of the user. The computing device responsively receives orientation data from the tracking device indicative of an orientation of the tracking device in a tracking device space. The computing device determines an orientation of the hand of the user in a hand tracking space from captured image data of the hand of the user and the tracking device. The computing device generates a transformation matrix to anchor the tracking device space to the hand tracking space. The tracking device resultantly enters an anchored state.

Abstract: Computer-implemented methods, systems, apparatus, and computer-readable media (transitory or non-transitory) are described herein for detecting eye tracking calibration errors. In various examples, respective poses of first and second eyes of a wearer of a head-mounted display (“HMD”) may be determined. A portion of a first image rendered on a first display of the HMD may be selected based on the pose of the first eye of the wearer. The selected portion of the first image may be matched to a portion of a second image rendered on a second display of the HMD. An eye tracking calibration error may be determined based on the pose of the second eye of the wearer and a location of the portion of the second image.

Abstract: A head mounted display assembly is provided. The head mounted display assembly comprises a head supported structural frame to support a display viewable by a user of the assembly, the structural frame including upper and lower surfaces. The assembly comprises a mounting interface on the lower surface of the structural frame, the mounting interface for releasably coupling an accessory device to the assembly. The mounting interface comprises a magnetic portion for attracting an opposing magnetic portion of the accessory device upon alignment of the accessory device with the mounting interface, and for repelling the magnetic portion of the accessory device upon misalignment of the accessory device with the mounting interface, and a communication interface for communicating data with the accessory device.

Abstract: In various examples, a head-mountable display (“HMD”) may include a light source to emit light across a target region of a wearer, a light sensor, and a circuitry operably coupled with the light source and the light sensor. The circuitry may operate the light source to periodically emit light across the light sensor. Based on a determination that a time interval since the circuitry last received a signal from the light sensor satisfies a threshold, the circuitry may trigger a remedial action to cause the light source to cease emission of light across the target region of the wearer.
