Abstract: Systems and methods are described that include generating a virtual environment for display in a head-mounted display device. The virtual environment may include at least one three-dimensional virtual object having a plurality of volumetric zones configured to receive virtual contact. The method may also include detecting a plurality of inputs corresponding to a plurality of actions performed in the virtual environment on the at least one three-dimensional virtual object. Each action corresponds to a plurality of positions and orientations associated with at least one tracked input device. The method may include generating, for each action and while detecting the plurality of inputs, a plurality of prediction models and determining based on the plurality of prediction models in which of the plurality of volumetric zones the at least one tracked input device is predicted to virtually collide.

Abstract: In at least one general aspect, a method can include determining a physics parameter based at least in part on a scale of user relative to an object in a virtual reality environment, applying a physics rule to an interaction between the user and the object in the virtual reality environment based on the physics parameter, and modifying the physics parameter based at least in part on a relative change in scale between the user and the object.

Abstract: Methods and apparatus to use predicted actions in VR environments are disclosed. An example method includes predicting a predicted time of a predicted virtual contact of a virtual reality controller with a virtual musical instrument, determining, based on at least one parameter of the predicted virtual contact, a characteristic of a virtual sound the musical instrument would make in response to the virtual contact, and initiating producing the sound before the predicted time of the virtual contact of the controller with the musical instrument.

Abstract: In a system and method for sharing items in an augmented and/or virtual reality environment, selected virtual items may be virtually propelled using, for example, a tossing or throwing motion, to a target recipient, so that the selected item may be shared with the target recipient without direct physical and/or virtual contact with the target recipient. Movement of a user's hand may be detected and tracked, so that the intended target recipient for the shared item may be identified based on a projected trajectory of a throwing motion of the user's hand. Associations between the user and different target recipients may cause different possible target recipients to exhibit different attractive forces, or different levels of magnetism, for particular items being tossed or thrown by a user for sharing, to further differentiate between the possible target recipients, and resolve recipient ambiguity.

Abstract: In at least one aspect, a method can include determining a location of a head mounted display (HMD) of a user, defining a location of a joint based on the location of the HMD, defining a segment from the joint to an end of the segment, defining an initial virtual location of a virtual controller within a virtual reality (VR) environment based on a location of the end of the segment, and defining a virtual location and a virtual orientation of the virtual controller within the VR environment, based on the segment and the joint, in response to an orientation movement of a physical controller.

Abstract: Techniques of displaying a virtual environment in a HMD involve generating a lighting scheme within a virtual environment configured to reveal a real object in a room in the virtual environment in response to a distance between a user in the room and the real object decreasing while the user is immersed in the virtual environment. Such a lighting scheme protects a user from injury resulting from collision with real objects in a room while immersed in a virtual environment.
