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: 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: 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.
