Abstract: The present disclosure is directed to providing a notification in association with an augmented reality (AR) view. In particular, one or more computing devices can generate, for display by at least one of the computing device(s), an interface depicting an AR view of at least a portion of a physical real-world environment. In accordance with aspects of the disclosure, based at least in part on detected movement of the at least one of the computing device(s), the computing device(s) can transition amongst multiple different stages of one or more elements included in the interface to notify a viewer of the interface to mind their situational awareness of the physical real-world environment.

Abstract: Systems and methods for rendering computer graphics using soft-occlusion are provided. A computing system can obtain display data for a virtual element to be displayed in association with imagery depicting an environment including a physical object. The computing system can generate a set of graphics occlusion parameters associated with rendering the image data and the display data based at least in a part on an estimated geometry of the physical object. The set of graphics occlusion parameters can define blending of the display data for the virtual element and the imagery at a soft-occlusion region that includes one or more locations within the estimated geometry. The computing system can render a composite image from the display data for the virtual element and the imagery based at least in part on the set of graphics occlusion parameters.

Abstract: A method for controlling a co-presence virtual environment for a first user and a second user includes: determining a first avatar's restricted space in the co-presence virtual environment, the first avatar correspond to the first user of the co-presence virtual environment; receiving user position data from a first computing device associated with the first user and determining the first avatar's location within the co-presence virtual environment; when the first avatar's location is within the first avatar's restricted space, communicating first co-presence virtual environment modification data to the first computing device; and communicating second co-presence virtual environment modification data to a second computing device associated with the second user.

Abstract: In one general aspect, a method can include triggering display of a virtual environment in a head mounted display (HMD) device operating in a physical environment, triggering display of a first virtual object representing a second virtual object, the first virtual object having a size smaller than a size of the second virtual object, receiving an indication of an interaction of a user with the first virtual object, the user having a first size larger than the size of the first virtual object, and triggering an interaction with the second virtual object in response to an interaction with the first virtual object, the user having a second size larger than the first size when interacting with the second virtual object.

Abstract: A system and method of operating an audio visual system generating an immersive virtual experience may include generating, by a head-mounted audio visual device, a virtual world immersive experience within a virtual space while physically moving within a physical space, displaying, by the head-mounted audio visual device within the virtual space, a visual target marker indicating a target location in the physical space, receiving, by the head-mounted audio visual device, a teleport control signal, and moving a virtual location of the head-mounted audio visual device within the virtual space from a first virtual location to a second virtual location in response to receiving the teleport control signal.

Abstract: In at least one general aspect, a method can include determining a position of a user in a virtual reality (VR) environment, determining a position of object in the VR environment, defining a vector between the position of the user and the position of the object, and defining an elongated collision volume along the vector. The elongated collision volume may have a medial portion around at least a portion of the object, a proximal portion disposed proximal to the object, and a distal portion disposed proximal to the object. The proximal portion may have a cross-sectional area less than a cross-sectional area of the distal portion.

Abstract: Example methods and apparatus to navigate within virtual-reality (VR) environments are disclosed. A disclosed example method includes defining a reachable portion of a VR environment, defining an unreachable portion of the VR environment separate from the reachable portion, and translating a physical hand location in the reachable portion into a virtual hand location in the unreachable portion.

Abstract: Techniques of computer animation involve embedding a keyframe editor within a virtual reality (VR) controller that displays animation objects within a VR environment on a VR display to enable editing of early keyframes. The keyframe editor allows a user to select a keyframe of an animation sequence for editing using the VR controller. The keyframe may be one that is placed before the end of the animation sequence. The keyframe editor also allows the user to select, via the VR controller, an aspect of the animation object to change within the selected keyframe. When an animation object follows a first trajectory before editing, the keyframe editor may automatically generate a second trajectory that preserves continuity of action.
