Visual immersion is an important aspect of virtual environments. This page lists a few interesting projects, including digital caves, and modular displays.

=== CAVE2 ===

[http://www.evl.uic.edu/core.php?mod=4&type=4&indi=824 CAVE2] is approximately 24 feet in diameter and 8 feet tall, and consists of 72 near-seamless passive-stereo off-axis-optimized 3D LCD panels, a 36-node high-performance computer cluster, a 20-speaker surround audio system, a 10-camera optical tracking system and a 100-Gigabit/second connection to the outside world.

=== ImmersaDesk2 ===

Essentially, the [http://www.evl.uic.edu/core.php?mod=4&type=1&indi=164 ImmersaDesk2™] is a dual purpose ImmersaDesk™ contained within a single large flight case. The press of a button activates the conversion of viewing angle from desk (45 degree) to vertical screen display, allowing for use as a traditional A-V presentation device, as well as an immersive virtual reality system. The display dimension is 83" diagonal, 1.3 ratio, using a rear projected low gain screen.

=== PARIS ===

The [http://www.evl.uic.edu/core.php?mod=4&type=1&indi=83 PARIS™] display has excellent contrast and variable lighting which allows hands to be seen immersed in the imagery. The current PARIS™ production prototype employs the Christie Mirage 2000 DLP projector and a double mirror-fold to compactly and brightly illuminate the overhead black screen.

=== LambdaTable ===

The [http://www.evl.uic.edu/core.php?mod=4&type=1&indi=305 LambdaTable] is a tiled LCD tabletop display connected to high-bandwidth optical networks that supports interactive group-based visualization of ultra-high-resolution data.
The camera tracking system for the LambdaTable is a scalable multi-camera computer vision architecture designed to track input from many simultaneous users interacting with a variety of different interface devices.

=== TacTile ===

[http://www.evl.uic.edu/core.php?mod=4&type=1&indi=392 TacTile] is a multi-touch 52-inch LCD tabletop display design to support collaborative applications through a highly intuitive, multi-user touch interface. Users can pan, zoom, and interact with highly detailed imagery and applications, in real-time, and with improved resolution and accuracy over displays based on video projection.

=== LambdaVision ===

[http://www.evl.uic.edu/core.php?mod=4&type=1&indi=273 LambdaVision] is an ultra-high-resolution visualization and networking instrument for research and education in geoscience, computer science and other research disciplines. LambdaVision consists of 55 LCD panels tiled to produce a 100Mpixel display.

=== LAIR ===

[http://irserver.ucd.ie/bitstream/handle/10197/1861/presence_lair.pdf?sequence=1 LAIR (Lightweight Affordable Immersion Room)] -
a 360 degree CAVE in University College Dublin. 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.

=== Immersive environment 20 years after the 1st CAVE ===

[http://elrond.informatik.tu-freiberg.de/papers/WorldComp2012/CGV2636.pdf In this paper] we report our experience in design and implementation of an immersive environments laboratory used for research and education. The principle design considerations were that the system be relatively low cost, easy to configure and maintain, and fit in a small space, considerations common to the design of many similar systems. The paper also summarizes advances in cost/performance and ease of use since the first CAVE systems for each of the principle elements of an immersive environment system.

=== DAVE - Definitely Affordable Virtual Environment. ===

[http://www.cgv.tugraz.at/dave DAVE] stands for Definitely Affordable Virtual Environment.
Affordable means that by mostly using standard hardware components we can greatly reduce costs compared to other commercial systems.

=== 5-screen desktop with Eyefinity ===

Similar things are possible with NVIDIA Technology.
Combine that with cheap interaction (e.g. using Kinect) and you get an immersive, desktop system.

=== A 3-screen rear projection system ===

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 :

# [http://www.unomaha.edu/biomech/pdf/Mukherjee_M%202009.pdf Another system] for upper limb robotic studies.

+=== FRAVE ===
+Especially w.r.t. portability have a look at the [http://wwwnavab.in.tum.de/Chair/PublicationDetail?pub=toennis2011frave 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.
