Title: Single camera vs 2 eyes
Post by: cDima on January 16, 2008, 04:19:43 AM
I have a feeling that this illusion of 3d space might be better on camera than live. The video shows the perspective of a single viewpoint, but we humans have two eyes. In theory, for the effect to be proper, one needs to align eyes with sensors very carefully. if not, the 3d effect will be disrupted.

I have not tried it out, so, share with me your impressions.

It probably also depends on people, the full experience is reached I guess with stéréoscopic vision, with that I guess you really have a static hollogram.

With stéréoscopic vision alone I guess if you have a an arrow coming out of the screen pointing to you when you are in front of the screen, the image will follow you when you move, and will always point at you.

With desktopvr I believe the arrow will remain immobile and will not point at you when you move.

I think both would be complementary, desktopvr with head tracking might give an illusion of proof but only when you move, and if you stop to move your brain will realise soon it's flat.

I posted this idea of johnny lee blog, to emulate the camera effect without a camera or technology and without shuting one eye.

I just saw alien vs predator and they use night vision googles in it.

Night vision googles are not binoculars, both eyes basically see the same image, so it's like you are watching through a camera, and there is no préservation of the stéréoscopic effect.

Thinking about that I remember when I was young I was playing with periscope.

So basically the idea is to have a google with two mini periscops that would make both your eyes see from the same point of view with same angle.
It would be kind of like you are looking from between your two eyes.

We can also imagine a similar google with two mirrors inclinated at 45 degres (north north-west direction) in front of each eye.
The right eye will be able to see through the glass, while the left eye will have is vision reflected on the both mirrors making the left eye see from the same angle than the right eye.

or maybe you can just hide one eye :D

Remember that this is only a tracking device that is independent of the display.

I don't see anything that would prevent current stereographic techniques to be used with this, such as lcd shutter glasses or even red/green lens techniques.

http://en.wikipedia.org/wiki/LCD_shutter_glasses

In fact, the use of shutter glasses would fit right in with the mounted IR lights.

This method of tracking is so simple, yet amazing, I cannot see why this could not be used in current games today, in both mono and stereo implementations (given enough refresh ability).  3dstereo.com has multiple shutter glasses for sale (as an example source) for ~$50-100.

I suspect that a cheap $5-10 IR glasses version would be best for the masses right now, but for CRT/high end LCD type PC users full stereographic IR tracking VR is well within reach.  In fact, it's lying there just begging to be used.

Figures that the shutter glasses ($110 for the full system) use an IR signal to sync with the refresh rate of the screen. This would create some tracking problems due to reflections and make use of a second wiimote for control impossible... they would need to be RF for this to work.

I would really like to play some COD4 with head-tracking and stereoscopic vision. That might be worth an extra $100.
