"Presence" is a weird thing, because you can kind of pop in and out of it quickly.

Was calibrating my DK2 yesterday and ran the demo scene (the desk with the stack of cards and soda can, etc). I tried to reach for the house plant and the can, knowing full well that they weren't there, and there was nothing triggered in my mind. Then I thought "it'd be fun to knock over the cards" and I swiped my arm through the space they would occupy, and my brain switched for a second or two and I fully expected to be hitting the cards and causing them to tumble. When it didn't happen, it was jarring, because it should have happened.

With the DK1 and DK2, those moments come almost randomly for me, and I keep wondering if we'll get to a point where they can be sustained for long periods of time, or if it'll be like those magic eye pictures where you finally see the sailboat and as long as you concentrate and don't blink you can keep looking at it.

From all of the accounts I have read the HTC Vive has already reached that point. I seriously can not wait for it to get released in just a few months!

I had a similar feeling when doing the DK2 Desk demo. I was doing the usual looking around then reached out to touch the virtual desk. I had forgotten how close I was to my real desk so when I touched the desk virtually I touch my real desk. This flipped something in my brain, no way could I be touching a virtual desk. It was a really incredible experience.

When I play Elite: Dangerous with DK2 and throttle/stick, I would tweak the position of the actual controllers on my desk so they matched the position of the virtual sticks in the game. The appearance of the virtual throttle/stick in the game is essentially a recreation of the actual model I have and the game is set up so the virtual hands move to mirror what I'm doing in real life.

Obviously with the current setup it doesn't detect my hands in real space so the on-screen motions only happen as I make them in real life but as long as I keep my hands on the controllers, the illusion is great. Move the stick a little to the right and the guy on screen, sitting in the same position does the same.

I think once they add a Leap/Kinect/RealSense type depth cam on the front of these HMDs you'll get some basic hand tracking for better representation. As the article says, it doesn't have to have the most realistic graphics if the feeling of actually seeing your "avatar" moving 1:1 with your actual motions flips some switch in your perception and it's easy to feel like the virtual person in the virtual environment is an extension of you in the real world.

I've played Elite: Dangerous a little bit and have been meaning to get a better control setup for it. The ship's cockpit has an amazing amount of depth to it. And I love how screens in your ship react to being looked at.

Agreed - the Rift consumer version is designed with comfort as a primary focus. I've seen a lot of first impressions mention how premium the Rift headset feels compared to competitors. I think Oculus has prioritized comfort over even basic VR features like room-scale support.

It is possible to wear the consumer version with glasses, or would you need contacts if you have vision problems?

As I've gotten older I don't tolerate contacts as well so most of my usage (dev unit v2 in my case) has been with glasses. My prescription is fairly strong so I already get a bit of distortion in peripheral vision. It's something I tune out in reality but in VR, it took a few minutes of getting used to. It wasn't bad but it's a lot like when you first put on a headset and you sort of learn to gaze straight ahead rather than looking at stuff at the edges of your vision while still looking forward.

I'm curious, can you use Oculus Rift without glasses? I tried google cardboard without glasses, and can see clearly even though I'm near-sighted, because the image is only inches from my eyes.

It's designed to accommodate glasses, and there are also 3rd parties developing custom lens inserts to match your prescription.

You can wear glasses but it will reduce your field of view.

As in real life.

Far more pronounced. The FOV reduction doesn't come from the glasses frame so much as it comes from the glasses moving your eyes further away from the headset lenses than they would be without the glasses.
