- Abstract
In this article, we propose a method to develop a low-cost visual occlusion device. This device is modified using three-dimensional (3-D) glasses (used to watch 3-D TV) that are operated via the active shutter technique. Because 3-D glasses are sold worldwide, they are readily available; moreover, the price of 3-D glasses is lower than that of other types of equipment used as the basis for visual occlusion devices. Three-dimensional glasses employing the active shutter technique have the same structure as do commercial visual occlusion devices; the modification of a voltage-driven liquid crystal display is fairly simple. In this study, we evaluated the response time and transparency of the proposed low-cost visual occlusion device; the experiments yielded reasonable results. The proposed visual occlusion device can be fabricated under a price of $100.
