With the boost of both cutting-edge technologies and capital strength, the Virtual Reality(VR) makes a fast progress in recent years. And a technical maturity is reached for VR to be commercialized. With both the virtual reality and the 3D cinema, a stereoscopic display is generated based on the binocular parallax. But virtual reality provides more depth cues (e.g. the motion parallax) with a strong immersion than the 3D cinema. The current generation of the virtual reality still faces a series of technical problems. Especially, the vertigo and the eye fatigue are the toughest problems impeding the long-term applications of the VR. This paper briefly discusses the 3D visual perception and the causes of the vertigo and the eye fatigue. A solution to this technological bottleneck is suggested: the Dynamic Light Field. In addition, various light field technologies are compared related to the photograph and the display. At the end, three types of the augmented reality (AR) are presented and the commercial development trend of the AR and the VR are analyzed from perspectives of social interaction and communication.
