one) What is 3DOF and 6DOF?

"DOF" stands for degrees of freedom. Think of moving vertically, horizontally, and rotating – these are all different degrees of motility. half-dozen degrees of freedom (6DOF) allows you lot to move effectually and collaborate with a virtual environs. Meaning, your head, controllers and torso motility in the infinite are all tracked.

three degrees of liberty (3DOF) only rotation is tracked. That means that but the rotation of your head and the direction your controller is pointing is tracked. 3DOF is most suited for videos and experiences, where 6DOF is used for more immersive VR games and experiences requiring movement**.

A tethered headset is one that uses a cablevision running from the headset to a powerful reckoner that'south capable of running VR games. The computer does the processing and provides power to the headset. The headset is simply used ad the computer screen.

Standalone ways there are no cables attached, and all the computing happens within the headset. There's no need for a powerful computer, then you can have standalone headsets anywhere you want!

3) What are tracking cameras?

VR headsets need a way to locate the thespian and track their movements in the virtual world. They practise this using a sensor similar to a camera.

6DOF headsets apply 1 of two types of tracking. External or exterior-in tracking uses sensors mounted on walls or tripods to track the player in the virtual world, and inside-out tracking uses cameras on the headset looking outward track changes in the actor'southward position.

3DOF headsets like the Oculus Become don't take external tracking sensors for locating the role player, but they tin rails head and controller move using other sensors inside the headset.
