Thus, for example, the US used a remote-control submarine to "virtually" take people to make a survey of fossils under the Arctic Sea. Filmed images were sent instantly back to NASA via satellite, then connected up with a head-mounted display, so that researchers could easily "dive in" to the undersea world to explore.
例如美國正在進行北極海古生物遺骸的調查計畫，就是以遙控潛水艇的方式，將所拍得的影像即時透過衛星傳回太空總署，再與頭盔顯示器連線，研究人員就可以輕鬆地「潛入」海底世界進行探勘和搜尋。
