Virtual reality display renewal

IVY，约克大学的沉浸式视觉环境，用于各种任务，从可视化复杂场景，到为心理物理和人类行为实验生成新环境。IVY是一个独特的8'x8‘x8’六面投影虚拟环境，由一组配备适当显卡的高端PC驱动。IVY的六面墙中的每一面都用来向IVY内的用户呈现后投影的立体图像。这让用户沉浸在高质量的视觉模拟中。自1999年以来，IVY的一个关键元素是用于向用户呈现视觉显示的投影仪。IVY的投影仪是1999年购买的，现在已经开始出现故障。这笔拨款寻求资金来更换常春藤的投影仪，使其能够继续运作并促进创新的科学研究。

IVY, the Immersive Visual environment at York, is used for a variety of tasks from visualizing complex scenes, to the generation of novel environments for psychophysical and human performance experiments. IVY is a unique 8'x8'x8' six-sided projective virtual environment powered by a cluster of high-end PC's with appropriate graphics cards. Each of the six walls of IVY are used to present rear-projected stereo imagery to the user within IVY. This surrounds the user with a high quality visual simulation of some alternate reality. In continuous use since 1999, a key element of IVY are the projectors used to present the visual display to the user. IVY's projectors were purchased in 1999 and are beginning to fail. This grant seeks funding to replace IVY's projectors so that it can continue to operate and facilitate innovative scientific research.
