2016 is regarded as the first year of virtual reality (VR) applications, and major technology companies such as Facebook, HTC, Sony, Samsung, LG and Google are actively rushing, except for launch. In addition to the head-mounted VR display device, VR image processing functions have also been added to smartphones to attract more consumers' attention. CM Industry Analyst Han Wenzhao Adding eye-catching new highlights, smart phones, VR design style [@C] 2016 is referred to as the first year of virtual reality (VR), major technology vendors including Facebook, HTC, Sony, Samsung And Google, etc., continue to demonstrate their determination to enter the VR field, not only to launch VR hardware devices, but also for upstream and downstream industry chains such as platforms, content and channels. The VR market also has different high- and low-level products. High-end VR head-mounted devices must be equipped with high-performance computers or game consoles. The low-end VR experience is the operation or screen function of the head-mounted device combined with the smartphone. Can be used. The VR head-mounted devices introduced by major manufacturers can be divided into two categories: "mobile" and "fixed" according to portability. Mobile refers to a head-mounted device that does not require an external line to a fixed computing device, such as a personal computer or a game machine. The user can still move without being restricted by space when wearing it; the fixed type refers to the need for external connection. The line to the above fixed device can only move within a certain range after being worn. Further subdividing the sub-category, the mobile VR includes "VR glasses" and "VR all-in-one". The former must be connected to a smartphone to provide virtual reality content through the computing and application of the mobile phone, and then presented to the user through the headset, some of which not only allow the mobile phone to provide computing, but also use the mobile phone directly as a screen. . VR glasses must have a better experience when the phone is highly compatible with the device. VR experience technology analysis Different VR headsets will affect the immersion experience of VR due to different technologies. The following will analyze the operating mechanism and technical project of the VR device and compare the experience gap between the current mobile and fixed VR headsets. The operating mechanism of the complete VR experience The VR experience process can be divided into two parts: “input†and “outputâ€. The VR hardware input device transmits the signal to the hardware processor and the software operating system through the identification function. After the operation processing, the hardware output device outputs the signal to the human body sensory, and the signal completes the transmission loop back and forth (Fig. 1). The above input devices include: a visual capture system, a microphone, a handlebar, a touch screen, a panoramic photography and a somatosensory device, and the output device includes: a screen, a surround sound, a headphone and an object vibration. The current VR head-mounted device can be used as an output screen. The mobile VR glasses such as the Samsung Gear VR are mainly input through the touch keys on the side of the device, in addition to the built-in head tracking and eye tracking. . Figure 1 Schematic diagram of the operation mechanism of the complete VR experience Source: MIC (3/2016) Fixed VR helmets such as the Oculus Rift VR and HTC Vive VR are better equipped with a handlebar, positioning tracker, etc. as input. However, no matter which type, the more input and output devices are connected, the delay will be aggravated.
