Abstract: Methods for matching online users in a networked interactive entertainment simulation are provided. In one aspect, a method includes receiving a user request for a user for joining an online session of the simulation. The user request is associated with a set of criteria for matching the user with other online users. An available population of users and a moving average of elapsed time to match for other users are determined. The set of criteria is adjusted based on the available population and the moving average of elapsed time. Finding other online users matching the adjusted set of criteria is initiated. The online session is started based on found online users. Systems and machine-readable media are also provided.

Abstract: Embodiments of a system and method for dynamically selecting a communication technology based at least in part on the success in forming a peer-to-peer connection for playing an instance of a video game are disclosed. Further, the systems may dynamically select a communication technology based on the quality of service of an established communication connection between two or more computing systems corresponding to two or more users attempting to play the instance of the video game. In some embodiments, the identification of a communication technology may occur during a gaming session and the communication technology used at the start of the game play session may be transitioned to another communication technology enabling the maintenance of a level of quality of service.

Abstract: Images of an eye are captured at respective time instances by a camera of a head-mounted device. For each time instance, a position of a center of corneal curvature is estimated using an image captured at that time instance, a position of a pupil center is estimated using an image captured at that time instance, and a line is determined through the estimated corneal curvature center position and the estimated pupil center position. A first estimated position of a center of the eye is computed based on the lines determined for time instances in a first time period. A second estimated position of the center of the eye is computed based on the lines determined for time instances in a second time period. Relocation of the head-mounted device relative to a user's head is detected based on the first and second estimated positions of the eye center.

Abstract: Systems, apparatuses, and methods for adjusting the compression level for blocks of a frame based on a distance of each block to the focus region are disclosed. A system includes a transmitter sending a video stream over a wireless link to a receiver. The transmitter compresses frames of the video stream prior to sending the frames to the receiver. For each block of pixels of a frame, the transmitter selects a compression level to apply to the block based on the distance from the block to the focus region, with the compression level increasing the further the block is from the focus region. The focus region is the portion of a half frame where each eye is expected to be focusing when viewed by a user. The transmitter encodes each block with the selected compression level and then conveys the encoded blocks to a receiver to be displayed.

Abstract: Images of an eye are captured by a camera. For each of the images, gaze data is obtained and a position of a pupil center is estimated in the image. The gaze data indicates a gaze point and/or gaze direction of the eye when the image was captured. A mapping is calibrated using the obtained gaze data and the estimated positions of the pupil center. The mapping maps positions of the pupil center in images captured by the camera to gaze points at a surface, or to gaze directions. A further image of the eye is captured by the camera. A position of the pupil center is estimated in the further image. Gaze tracking is performed using the calibrated mapping and the estimated position of the pupil center in the further image. These steps may for example be performed at a HMD.

Abstract: There is provided a method and system for determining if a head-mounted device for extended reality (XR) is correctly positioned on a user, and optionally performing a position correction procedure if the head-mounted device is determined to be incorrectly positioned on the user. Embodiments include: performing eye tracking by estimating, based on a first image of a first eye of the user, a position of a pupil in two dimensions; determining whether the estimated position of the pupil of the first eye is within a predetermined allowable area in the first image; and, if the determined position of the pupil of the first eye is inside the predetermined allowable area, concluding that the head-mounted device is correctly positioned on the user; or, if the determined position of the pupil of the first eye is outside the predetermined allowable area, concluding that the head-mounted device is incorrectly positioned on the user.

Abstract: In some embodiments, a computer-implemented method for retrieving a similar document from a corpus of documents is provided. The method may include receiving a search document comprising a set of words; applying a first encoder to generate a first vector; applying a second encoder to generate a second vector; determining a first similarity between the first vector of the search document and the first vector of each document of the corpus of documents; determining a second similarity between the second vector of the search document and the second vector of each document of the corpus of documents; generating a first ranked list of documents based on the first similarity; generating a second ranked list of documents based on the second similarity; applying a voting algorithm to determine a score associated with each document; and outputting a third ranked list of documents based on the determined score.

Abstract: A matchmaking system matches players for online gaming, when some of the players may be streaming players and other players may be non-streaming players. The streaming players, due to receiving content of the online game via computer networks from a streaming system, may experience a relatively greater network latency for game events relative to non-streaming players. When matching streaming players and non-streaming players for online game play, the relative competitive disadvantage for streaming players due to network latency may be compensated. Additionally, streaming players using input devices that may be more difficult to use and/or may be less responsive during game play, such as a touch screen, may also have their input device disadvantage compensated during matchmaking.

Abstract: A system and method optimizes game quality by matching players for an online game to one of several virtual games. This matching process may involve filtering the players who wish to play according to various constraint minimizing criteria, packing the players into one or more virtual games to optimize game quality factors of the virtual games, and then instantiating the virtual games to actual online games played by the players. The game packing process may be iterative and may involve adding a new player into a virtual game. Game quality factor (GQF) values prior to and after the placement of the new player in the virtual game may be compared. The comparison of the GQF values may be used, at least in part to determine whether the new player is to remain in the virtual game. Various criteria may be considered in instantiating a virtual game.
