I totally forgot about seeing the world through another person's eyes in the original Psychonauts, but it provides a perfect explanation here for teleporting between different spots in VR, I like it.
@supapuerco: Just for the sake of completion, the full requirements they list (anticipating Touch as you said) is 3x USB3.0 ports + 1x USB2.0 port. The latter is for the bundled XBone controller. The others are for Rift & camera sensor (2 ports) plus a second camera (1 port) for using Touch controllers.
