Samsung and Oculus created a VR headset that uses a Galaxy Note 4, Galaxy S6 or S6 Edge phone to stunning effect. Panoramic movies, 3D games, and weird virtual worlds are all available, but you need to interact with a game controller or a side-mounted touchpad.
Unfold it, put it on your phone, and go on a magic carpet ride: Google Cardboard is the most affordable way to try VR right now. It works with tons of iPhone and Android apps, but you have to hold it up in one hand like a pair of opera glasses.
Sony's PlayStation 4-compatible VR headset system works with its own games and uses older PlayStation Move controllers. Graphics look a little lower-res than PC-based rigs, but still impressive. Eric Franklin, seen here, gives them a shake.
Oculus Touch is one of several next-wave controllers designed for virtual reality. Advanced motion controls, vibrating haptic feedback, and 3D room-sensing cameras will help create new ways of interacting in the next few years.
