Do you lose the space behind the lighthouses?
What I mean by that is that they will jut out a bit from the wall due to the mounting fixtures. When tracing your play area, can you go right to the wall, or does it have to stop at the front of the lighthouse?
You'll lose a little bit, but can compensate depending on the angle you tilt at. Eg if you tilt it 30 degrees down, the field of view should be directly below the lighthouse. If you tilt it 45 degrees down it'll then scan 15 degrees behind itself, so by the time it hits the floor you'll have some extra space tracked, but there will be a black spot closer to the lighthouse. I suppose the best you could get would be 60 degrees down, as that should still track across horizontally, plus it'd track 30 degrees behind itself. You'd probably need to ceiling mount though as the tilting brackets don't seem to go that far - probably around 45 degrees max.
Just went through The Lab and a bit of virtual desktop. The Lab is a lot of fun but I actually noticed the screen door more than when I had my first demo. You can tune it out but its always there. And the fresnel ring 'glow' with high contrast objects. Not too bad though.
Virtual desktop is fun but I really wish you could use the vive controllers as a mouse - I moved my wireless keyboard/mouse to my tracked area (my PC isn't in that area) but it wasn't ideal, and you obviously can't see your mouse/kb but you can see the vive controllers.
Got a little uncomfortable after a while - it was pressing on the left side of the back of my head. Had the rear 'bracket' high up like recommended. Also need to play with the headphones as they were bloody annoying, constantly getting pulled about by the main cable. I want to also take some of the strain off the back of my head by somehow clipping the cable to my belt (with enough slack..)
my room is pretty small though - 2m x 2m and you basically get the chaperone pop up as soon as you put an arm out in any direction. Basically a standing experience - even in the lab experiences you can almost never walk to something so you just teleport close, which is fine but I think 3x3 would be a big improvement. Might try moving my PC to the living room for a test, as I think I can clear that space, plus one of the walls would be a sofa so not a hard stop like my spare room is. I think with the current space I'd be constantly wary of hitting something (I did hit my room light when throwing a stick for the aperture science dog)
