PlayStation VR needs 60-square feet of space to use.

Sony’s upcoming PlayStation VR headset will require just about 60 square feet of space, it also asks that players remain seated whenever possible while playing, according to new documentation released by the company.

The PlayStation camera which you need to use the headset needs a cleared play area of about 9.8 feet by 6.2 feet, according to a sales brochure.

“Limit your use of PS VR to within the Play Area,” according to the brochure. “Clear an area larger than the Play Area of all obstacles before using PS VR and remain seated whenever possible. If the application requires you to stand while wearing the VR headset, follow the application instructions carefully, and maintain awareness of your surroundings.”

The height of the play area depends on where you place your camera. Another source says to try out the PS VR in a store before purchasing it.

“PS VR uses 3D vision technology,” according to the site. “As there are individual difference in viewing 3D graphics and feeling of wearing VR headset, please try PS VR at shops or trial events before purchase.”

This report seems to be very odd since I’ve used the PlayStation VR at PAX East playing Thumper and the area was in basically a small corner and it worked perfectly fine.
