How can a tiny cardboard box make you feel like you're miles away at a sandy beach? And why aren't we all living in a virtual world right now, if it all seems so great? Valentina Shin, a Ph.D. student in the Computer Graphics Group at MIT's Computer Science & Artificial Intelligence Laboratory, explains!

Ahh I was wondering how my vr headset games had such depth to them in such a little box. So our brain creates a sense of depth by how off-set the two independent images recieved by our eyes are ..that is very interesting and clears alot of things up so thanks! :)

yes I noticed how the thumb jumps a little bit to the left or right when I switch between my eyes. And right when I bring my thumb a little bit closer to me it does jump even more

Slight mistake at 2:18: Cardboard only tracks head rotation, not position.

how can i look around with out needing the mouse? ive tried watching a few of these videos in oculus but it does not track my head and i just see a youtube window as i would on my desktop and need to use my hand controllers to click and drag the small window.

@jonathanlee6660 4 жыл бұрын

U need to open the video in a seperate application, theres one on the oculus store. It's free just look for it

@inconnn 4 жыл бұрын

On PlayStation VR, I must squint my eyes to look at near objects and unsquint them to focus on far ones. No one on the whole internet seems to have noticed that and it seems impossible to find a single explaination on how the heck that is made possible! Is google censuring psvr?

@mrexotics3308 6 жыл бұрын

Does it do that still? i'm wanting to buy one but i'm unsure

@riyokar6159 3 жыл бұрын

I don't have that problem on my Oculus Quest 2. I recently switched to pc and I can say ps4 doesn't have the best of graphics, probably the texture quality and so on may cause it or maybe a technical issue with the psvr?

There is more to the creation of 3D in one's brain than you explain. The brain uses other key factors as well. One is the fact that objects which are close move faster than objects which are far away as angles change.. Another is focus on the fovia. All of these factors and others create 3D immersion. The "separation" 3D found in today's VR HMD's is good, but needs continued improvement. Oculus is working very hard to improve these other factors and recently filed a patent on one of them which they claim to be significant and intend to incorporate in the future. Hey, you're MIT.... know the facts !

@shevyb1913 3 жыл бұрын

its because vr tricks you into thinking that things are far away and close, they are not actually like that, it just creates a sense of how far away stuff is

Just got done watching the video. Such a cool concept. Imagine if we could see 5D things. We wouldn't be able to live. It would be too much to handle for our brain. We would lose our shiz.

+Marzia Rizvi Thanks! I know, right? We were losing our shiz just producing this video :D
