Abstract: A wearable display system for a cross reality (XR) system may have a dynamic vision sensor (DVS) camera and a color camera. At least one of the cameras may be a plenoptic camera. The wearable display system may dynamically restrict processing of image data from either or both cameras based on detected conditions and XR function being performed. For tracking an object, image information may be processed for patches of a field of view of either or both cameras corresponding to the object. The object may be tracked based on asynchronously acquired events indicating changes within the patches. Stereoscopic or other types of image information may be used when event-based object tacking yields an inadequate quality metric. The tracked object may be a user's hand or a stationary object in the physical world, enabling calculation of the pose of the wearable display system and of the wearer's head.

Abstract: A wearable display system with a limited number of cameras. Two cameras can be arranged to provide an overlapping central view field and a peripheral view field associated with one of the two cameras. A third camera can be arranged to provide a color view field overlapping the central view field. The wearable display system may be coupled to a processor configured to generate a world model and track hand motion in the central view field using the two cameras. The processor may be configured to perform a calibration routine to compensate for distortions during use of the wearable display system. The processor may be configured to identify and address portions of the world model including incomplete depth information by obtaining additional depth information, such as by enabling emitters, detecting planar surfaces in the physical world, or identifying relevant object templates in the world model.

Abstract: A high-resolution image sensor suitable for use in an augmented reality (AR) system. The AR system may be small enough to be packaged within a wearable device such as a set of goggles or mounted on a frame resembling ordinary eyeglasses. The image sensor may have pixels configured to output events indicating changes in sensed IR light. Those pixels may be sensitive to IR light of the same frequency source as an active IR light source, and may be part of an eye tracking camera, oriented toward a user's eye. Changes in IR light may be used to determine the location of the user's pupil, which may be used in rendering virtual objects. The events may be generated and processed at a high rate, enabling the system to render the virtual object based on the user's gaze so that the virtual object will appear more realistic to the user.

Abstract: A high-resolution image sensor suitable for use in an augmented reality (AR) system to provide low latency image analysis with low power consumption. The AR system can be compact, and may be small enough to be packaged within a wearable device such as a set of goggles or mounted on a frame resembling ordinary eyeglasses. The image sensor may receive information about a region of an imaging array associated with a movable object, selectively output imaging information for that region, and synchronously output high-resolution image frames. The region may be updated dynamically as the image sensor and/or the object moves. The image sensor may output the high-resolution image frames less frequently than the region being updated when the image sensor and/or the object moves. Such an image sensor provides a small amount of data from which object information used in rendering an AR scene can be developed.

Such an image sensor provides a small amount of data from which object information used in rendering an augmented reality scene can be developed. The amount of data may be further reduced by configuring the image sensor to output indications of pixels for which the measured intensity of incident light changes.

Abstract: Forming a 3D representation of an object using a portable electronic device with a camera. A sequence of image frames, captured with the camera may be processed to generate 3D information about the object. This 3D information may be used to present a visual representation of the object as real-time feedback to a user, indicating confidence of 3D information for regions of the object. Feedback may be a composite image based on surfaces in a 3D model derived from the 3D information given visual characteristics derived from the image frames. The 3D information may be used in a number of ways, including as an input to a 3D printer or an input, representing, in whole or in part, an avatar for a game or other purposes. To enable processing to be performed on a portable device, a portion of the image frames may be selected for processing with higher resolution.

Abstract: A computer peripheral that operates either as a computer mouse or as a scanner. The peripheral includes navigation sensors that generate information on motion of the device and an image array that captures successive image frames of an object being scanned. In a mouse mode, the peripheral periodically transfers readings from the navigation sensors to a computing device so that the computing device can track a position of the device. In a scanner mode, in addition to obtaining navigation information from the navigation sensors, the peripheral also captures image frames as it is moved across the object. Operation of the navigation sensors and image array may be synchronized such that an association between the image data and the navigation information may be generated and maintained as image frames are transferred to the computing device, even if some of the frames are dropped in transmission between the scanner-mouse and a computer.
