HTC Vive’s user manual details elaborate setup process, including moving your couch

You’re going to need a large area to enjoy the full capabilities of the HTC Vive virtual reality headset. VR watchers have always known this. But now, they’re finally getting the specifics.

HTC has uploaded the user guide for its Vive PRE development kit, which is the latest version of the head-mounted display, and one it’s sending out to studios and designers. This manual is an in-depth explanation of the kind of room and area you’ll need to prepare if you want to use the Steam VR-powered room-scale technology that sets the Vive apart from competitors like Oculus Rift. This is the feature that enables you to stand up and walk around a simulated environment — it is the reason we love what we’ve tried of the Vive so far.
