虚拟现实系统使引人注目的外展显示，但一些系统非常适合外展，特别是CAVE，具有使其用于该目的不方便的设计特征。在CAVE的情况下，设备很难拆卸，运输和重新组装，通常只有大预算的研究设施才能负担得起这样的系统。
我们实现了一个像CAVE这样的系统，它的成本不到3万美元，重约500磅，适合装在一辆15人的货车里。一个由六人组成的团队在不到两个小时的时间内完成了系统的拆包、组装和校准。
与类似的虚拟现实系统相比，这种成本降低源于我们对立体投影采取的独特方法。我们使用光学斩波轮和商品LCD投影机的组件来创建真正的主动立体声，成本不到可比主动立体声技术的五分之一。
屏幕和框架的设计也港口便携性优化;框架组装在几分钟内只有两个紧固件，都包装成小捆，方便和安全的运输。
Virtual reality systems make compelling outreach displays, but some systems highly suitable for outreach, notably the CAVE, have design features that make using them for that purpose inconvenient. In the case of the CAVE, the equipment is difficult to disassemble, transport, and reassemble, and typically only large-budget research facilities can afford such a system.
We implemented a system like the CAVE that costs less than $30,000, weighs about 500 pounds, and fits into a fifteen-passenger van. A team of six people have unpacked, assembled, and calibrated the system in less than two hours.
This cost reduction versus similar virtual reality systems stems from the unique approach we took to stereoscopic projection. We used an assembly of optical chopper wheels and commodity LCD projectors to create true active stereo at less than a fifth of the cost of comparable active stereo technologies.
The screen and frame design also harbor portability optimizations; the frame assembles in minutes with only two fasteners, and both pack into small bundles for easy and secure shipment.
