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.
