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: In a system for moving, or dragging, a virtual reality environment, a user wearing a head mounted display (HMD) device may be at a first physical position in a physical space, corresponding to a first virtual position in the virtual environment. The user may select a second virtual position in the virtual environment by, for example, manipulation of a handheld electronic device operably coupled to the HMD. The system may construct a three dimensional complex proxy surface based on the first and second virtual positions, and may move the virtual elements of the virtual environment along the proxy surface. This movement of the virtual environment may be perceived by the user as a move from the first virtual position to the second virtual position, although the user may remain at the first physical position within the physical space.

Abstract: In a control system for navigating in a virtual reality environment, a user may select a virtual feature in the virtual environment, and set an anchor point on the selected feature. The user may then move, or adjust position, relative to the feature, and/or move and/or scale the feature in the virtual environment, maintaining the portions of the feature at the set anchor point within the user's field of view of the virtual environment.
