1. A method to facilitate one or more virtual interactions with a three-dimensional virtual environment displayed on a display system in response to user input at a control device coupled to the display system, the method comprising: controlling a display system to effectuate presentation of a three-dimensional virtual environment, the three-dimensional virtual environment being presented over views of a real world such that the three-dimensional virtual environment is perceived to be in a first region in the real world, the display system including a headset configured to be worn by a user; receiving a sensor signal from one or more sensors coupled to a control device comprising a mobile phone or a tablet computer, the sensor signal conveying a representation of physical movement by a user interaction element within a specified three-dimensional physical region, the three-dimensional physical region comprising a second region in the real world, the second region being separate and distinct from the first region, the user interaction element being associated with the user, the physical movement by the user interaction element being devoid of physical contact with the control device; translating the representation of the physical movement into a virtual interaction by the user with the three-dimensional virtual environment; identifying a virtual action in the three-dimensional virtual environment, the virtual action corresponding to the virtual interaction; and providing instructions to the display system to display the virtual action.
