The latest update of the test version of the Oculus PC software adds driver and software support for the upcoming Oculus Rift S. headset. Looking at the code, we can see the new Guardian setup process, as well as what happens after.

Guardian is the border that keeps you from colliding with walls in VR. It marks the edges of your gaming space in VR.

On the first Rift, you set up the Guardian before putting on the headset, going around the room with the touch controller. When drawing the border on the monitor was shown from top to bottom.

At Rift S and Quest, this process is different due to the lack of external cameras. Now you mark the boundaries of the Guardian right by the headset. You see the real world in black and white and use touch controllers to point and “draw” Guardian lines on a real area. Essentially – everything happens in the form of augmented reality:

If you need to expand the border, you do not need to redraw it. You can simply draw another line outside the current lines, and it will expand.

Floor calibration

To establish the position of the floor on the first Rift, you must stand exactly to its full height. From your height and headset position, he calculated the position of the floor. This was done because when the Rift sensor is placed by default, the sensors cannot see the floor.

Since the Rift S and Quest cameras can see the floor when you simply look down, the floor height is now set by touching the controller to the ground.

Automatic Passthrough Activation

Customizing the Guardian is not the only change. When you move your head out of your Guardian area, the headset will disappear again into the black and white “passthrough” camera, allowing you to see the wall or furniture you are about to bump into.
This can increase situational awareness in VR and make the room a safer space for virtual reality adventures.

Introductory Tutorial

When the setup is complete, you move to a new introductory experience for the Rift S, which explains the basics of VR and touch controls.
