Abstract: A computer-implemented method for determining if a player has reached a certain level of gameplay-performance while playing a game within a virtual reality, VR, environment. The player wears a headset having a display for viewing the VR environment and an object tracking system. The headset's object tracking system is capable of tracking movement of a portion of the player in 3-D space to establish an actual-response path by the player during gameplay. The method includes calculating, at a first time, an ideal-response path of gameplay for the tracked portion of the player in 3-D space. The ideal-response path is the path that will achieve the certain level of gameplay performance. The method then compares, at a second time, the actual-response path with the calculated ideal-response path, and finally indicates, in response to a match in the comparing step, that the play has reached a certain level of gameplay performance.

The parameters of a first one of the driver assist features are applied to output a first target set of one or more targets selected from a set of candidate objects for the first one of the driver assist features, and then parameters of a second one of the driver assist feature are applied to output a second target set of one or more targets selected from the set of candidate objects for the second one of the driver assist features.

Abstract: Examples of the present disclosure describe systems and methods relating to full motion video (FMV) routing in one-way transfer (OWT) systems. The present technology reserves a particular channel for transmission of a video stream, and then transmits the video stream from a low-trust computing environment to a high-trust computing environment along a data path defined by the channel. When the video stream is received on the high-trust side, the channel, on which the video stream is received, is determined and used to query a routing table that returns destination addresses of destination devices to which the video stream is to be transmitted. The video stream is then delivered to the destination devices having the corresponding addresses.

After an unsuccessful comparison, the authentication server transmits, to the backend server, a notification indicating an unsuccessful authentication to the backend server.

Abstract: The present disclosure describes systems and methods relating to full motion video (FMV) routing in one-way transfer (OWT) systems. The present technology enriches the datagrams of the video stream that are sent from the low-trust side of the OWT system with a global unique identifier (GUID) that is used as an identifier to determine a particular destination on the high-trust side of the OWT system. The enriched video stream is then transmitted through an OWT system that provide high reliability for the enriched video stream. When the enriched video stream is received on the high-trust side, the GUID in the datagram is extracted and used to identify destination addresses for destination devices in the high-trust computing environment. The video stream is then delivered to the destination devices having the corresponding destination addresses.
