This allows the user to "enter" the virtual world, as if one's body were actually present in the computer-generated space. The beauty of visual reality technology is that the user can touch, move, and interact with people and objects in the surroundings.
綜合視覺、聽覺、觸覺等感官認知模式的模擬，隔絕來自真實世界的訊息，讓使用者「融入」，彷彿置身於電腦虛構的空間，並能與環境中的人或物體動手動腳地互動溝通，就是 VR 科技的精髓。
