Speaking of VR, the two leading virtual reality head-mounted displays (HMD) are very different in how they’re intended to be used.
Although the Oculus Rift has head-tracking, it is intended more for playing games in a seated or standing position with extremely limited amounts of head movement. You can think of this as being limited to a cockpit in a jet or the passenger area of a car or mech. The player can look out, and control movement of the vehicle they’re in with a gamepad, but if they get up and walk around they’re still trapped inside that vehicle or cockpit. This is perfect for games like Elite: Dangerous and the Eve: Valkyrie game that will be included with the Rift.
You can also display something with a more traditional third-person camera viewpoint outside of the avatar and have player movement bound to analog sticks on a gamepad or some other controller. That is what you have with Lucky’s Tale:
Many traditional 3D games involve a lot of player movement and a first-person perspective, so being limited to one position in the physical world isn’t quite as immersive as being able to move in a physical space and have that movement be reflected in the virtual world. This is more of the holodeck, or room-scale style of VR. I received a brief demo of this at Valve a few years ago. It is amazing when experienced in action. Valve’s SteamVR system offers this in addition to the ability to play cockpit-style games in a seated or standing position. It’s the main difference between the two headsets. Some games can work on both types.
Holodeck experiences have their downsides. Players need a fairly large space that is empty of obstructions in which to move. You’ll also need to install devices that Valve and HTC are calling lighthouses to define the physical space in which you’ll move and track your physical movement in that space. It’s not something everyone has space for, and although you can adjust the amount of physical space for use with this system you basically need a multi-room house or office to set up that experience. Valve had a few dedicated rooms for it.
It’s been almost impossible to demonstrate that room-scale experience without using it. The Northways, Colin and Sarah, have a video up that demonstrates the perspective of a player in the HTC/SteamVR Vive HMD while playing their Fantastic Contraption:
That’s a clip from a longer stream that you can watch here. The only difference between this and the real thing is that she can’t see the people on the couch while playing, and it’s way more fun to play in-person than watch on a stream.
