We use a 3-screen rear projection system in our lab (Nebraska Biomechanics Core Facility) which could be something you are looking for our locomotion studies. Check these publications from our lab :

we have another system for upper limb robotic studies:

Let me know if you need more information.

Good luck!

I'd suggest looking at some of the following, though none will give you 180-360 degree views, ultimately. You might consider a smaller version of the just-introduced CAVE2 (http://www.evl.uic.edu/core.php?mod=4&type=4&indi=824).

A scaled down LambdaVision setup might be worth looking at, too: http://www.evl.uic.edu/core.php?mod=4&type=1&indi=273

Good luck with your efforts.

We have a 360 degree CAVE in University College Dublin, (we have named it the LAIR , Lightweight Affordable Immersion Room) Its a quite unique front projected CAVE that allows a user to stand in the centre without casting a shadow. It was designed to be run using a single server machine so its a relativity cheap setup. As it runs on a single box so it can be moved around a bit , but the configuration if you used micro projectors and portable screens could be quite mobile.

University of Texas have built on this idea and other cost efficiency CAVE's and have made a 3 wall projector setup and added a really nice innovation of a 4 projector per wall setup discussed in the paper below

Also DAVE Definitely Affordable Virtual Environment. Affordable in Austria too is a great CAVE concept.

Hope that's some help to you, again if you need more information let me know.

An interesting question - reflecting the issue of immersion - the more engrossed the user is in the task (simulation) the easier it is to avoid distraction and frame refresh rates of less than 10fps are adequate for peripheral view updates. this would suggest that it is possible, and would obviously have a really significant market potential. Whilst we are working on 3D displays, I am not aware of such a system presently.

Especially w.r.t. portability you could have a look at the FRAVE system. Its called a flexibly reconfigurable CAVE. It however looses some immersion due to large bezels (as with our displays used; other, newer displays surely reduce this issue if this is a demand of yours) but can be physically restructured to powerwall-like setups or any layout.

They have virtual reality hypnotherapy.

We have made a mini-cave (peripersonal-CAVE) at PERCRO, which is roughly two meters wide and instead of the floor has a table.

Several companies now make a fully-portable immersive VR systems, complete with simple head wear. I have a research team working with desktop VR using large hi-resolution screens. We are currently testing empirically through small-scale experiments the efficacy of the large screens as opposed to smaller ones. The big differences appears to be the sense of "presence" that occurs with larger screens.

@Lynna - any pointers for the portable immersive systems you mentioned, and to your desktop VR project?

Our desktop CAVE system cannot handle 360º, but it has interesting features: http://dl.acm.org/citation.cfm?id=1990739

One can deform the images from the back of the user and fit them on the side displays for 360º.

You should also try an extended version provisionally published on the ACM-CiE website here: http://cie.acm.org/articles/improving-gameplay-first-person-3-d-games-using-multiple-displays/

It will be on the http://dl.acm.org soon.

A great high-tech, low cost solution

Anyone considered the possibility of using Oculus Rift (www.oculusvr.com) as a head-mounted immersive system?

Base on these Youtube videos:

1) http://www.youtube.com/watch?v=KJo12Hz_BVI (you can obviously look behind you, i.e. 360º)

2) http://www.youtube.com/watch?v=pAC5SeNH8jw (suitable for all ages)

Note: the fisheye lens are supposed to compensate for the 'video' and what you see through the Rift will be like 'real' world (I am referring to some of the other Rift video that looks funny on Youtube.)

here at the University of Hull some colleagues have a plan for working on it. My understanding is that the Oculus rift is not yet as available as just order and get it; If my information is correct they will get them soon. Drop me a message after summer and I might be able to give you more up to date info on this.

Thanks Jose, it would be an interesting setup. I will follow you as a reminder. :)

Could you please, share information how approximately 3D VR CAVE costs. Our team is writing project proposal and we need to calculate a budget for it.

Thank you in advance!
