Abstract: An audio system for a wearable device dynamically updates acoustic transfer functions. The audio system is configured to estimate a direction of arrival (DoA) of each sound source detected by a microphone array relative to a position of the wearable device within a local area. The audio system may track the movement of each sound source. The audio system may form a beam in the direction of each sound source. The audio system may identify and classify each sound source based on the sound source properties. Based on the DoA estimates, the movement tracking, and the beamforming, the audio system generates or updates the acoustic transfer functions for the sound sources.

Abstract: A rhythm-based video game (“game”) is disclosed. In the game, a player slashes blocks representing musical beats using a pair of energy blades resembling a lightsaber. A gaming console renders multiple digital objects, e.g., digital blocks, digital mines and digital obstacles, that are approaching a player in a virtual space. The gaming console also renders a digital representation of an instrument, e.g., a lightsaber (“digital saber”), using which the player slashes, cuts or otherwise interacts with the digital blocks to cause a digital collision between the digital saber and the digital blocks. The player can score by slashing the digital blocks, not hitting the digital mines and avoiding the digital obstacles. The game presents the player with a stream of approaching digital objects in synchronization with music, e.g., a song's beats, being played in the game. The pace at which the digital blocks approach the player increases with the beats.

Abstract: In one embodiment, a computing system may access a dead pixel position corresponding to a dead pixel of a display. The dead pixel may be associated with one of three color channels of the display. The system may access an image and select a set of three masks based on the color channel of the dead pixel. The system may modify the image by applying the set of three masks to a pixel region of the image containing a particular pixel value with a position that corresponds to the dead pixel position. The set of three masks may be respectively applied to three color channels of pixel values in the pixel region of the image. The set of three masks may be configured to minimize an error caused by the dead pixel in an opponent color space. The system may cause the modified image to be output by the display.

Abstract: A scanning type display device includes a light source that includes multiple rows and columns of light emitters. The display device also includes a rotatable mirror that projects light to different areas of an image field as the mirror rotates. There can be a redundant number to light emitters in the light source to increase the brightness of the pixels in the image field. A data driver may replicate and shift data values among light emitters of the same columns. The light emitters may operate in conjunction with the mirror in a synchronized manner. Owing to the shift in data value and the rotation of the mirror, the mirror may first project light from a first light emitter to a pixel and may then project light from a second light emitter with the same brightness level to the same pixel. The shifting may continue for additional light emitters.
