Abstract: Aspects of the present disclosure provide an automatic fixed-radius boundary for accessing artificial reality (XR) experiences. Instead of requiring a user to look around a real-world environment with an XR system and/or trace the available floorspace for a boundary, an automatic boundary system can create a boundary of fixed size around the user by using depth sensing to dynamically identify obstacles within the boundary as the user moves. The automatic boundary system does not require identification of the objects themselves, nor does it require that the entire real-world space be scanned in areas far from the user (e.g., outside the fixed radius). As the automatic boundary system detects obstacles, the XR system can display the obstacle as a mesh or in pass-through based on fulfillment of one or more conditions (e.g., the XR system or a body part of the user approaching the obstacle).

Abstract: This disclosure presents a distributed automated driving system for autonomous vehicles operating in long-tail scenarios. These long-tail scenarios comprise adverse weather conditions, adverse road conditions, disaster, and/or a failure of a vehicle component or function. During operation of an autonomous vehicle, some of its automated driving capabilities for sensing, prediction, planning, decision-making, or control may be downgraded due to long-tail events. The intelligent roadside toolbox (IRT) functions as an edge server or a cloud and can supplement the vehicle's sensing, prediction, planning and decision-making, and control functions by providing customized, on demand, and dynamic computing resources and functions to the vehicle. In addition, the IRT computing functions provide computation support for sensing, prediction, planning, decision-making, and/or control functions of the vehicle.

Abstract: This invention presents a function allocation system for an autonomous vehicle (AV). During the operations of the AV, some or all of its automated driving capabilities or functions could be downgraded due to long-tail events or malfunctioning. The roadside intelligent infrastructure, or the cloud platform, could supplement some or all of AV's automated driving functions, including sensing, prediction and decision-making, and/or control functions. The function allocation system dynamically allocates these functions between AV and intelligent infrastructure, achieving a higher system intelligence level S than the downgraded vehicle intelligence level V. In addition, a function allocation system could dynamically allocate sensing, prediction and decision-making, and/or control functions between AV and a cloud platform. This invention also presents a function integration system or a fusion system for an AV.

Abstract: The present technology relates to systems and methods that allocate, arrange, and distribute certain types of functions and intelligence for autonomous driving systems (ADS) to facilitate vehicle operations and controls; to improve the safety of an autonomous vehicle (AV); and to ensure the efficiency, intelligence, reliability, and resilience of ADS. The present technology also provides methods to define ADS system intelligence and its levels, which are based on two dimensions: the vehicle intelligence and the cloud intelligence. The cloud intelligence supports and complements the vehicle intelligence when a vehicle is impaired or handicapped for certain functions (sensing, prediction, decision, and/or control) during operations in abnormal conditions. Distribution of driving intelligence between the AV and the cloud facilitates safe operations of the AV for long-tail corner cases.
