The most straightforward introduction to Daydream VR

Virtual reality (virtual Reality), or fictitious technology, also known as virtual environment, is the use of computer simulation to generate a three-degree space virtual world, providing users with visual and other sensory simulation, so that users like immersive general, the computer can be immediately complex operation, The accurate three-dimensional world video is transmitted back to create a sense of telepresence.

This year has undoubtedly been VR take-off year, but the Android phone side of the low-end/simple VR device, but faced with hardware and software tuning of the dual problem. Upgrade the hardware of the part of the mobile phone factory to try again, but at least the software here Google can also help a bit. Google's "daydream" platform, published today on Google I/O, is divided into three main components, namely, the VR model for enhancing the response speed of mobile phones, the hood and remote hardware design for mobile phone operators, and the VR content platform.

Software
Android N is about to be built in this "VR mode", which can be seen as a special high speed mode for smartphones dedicated. According to Google Android Engineering vice-president Dave Burke said, a mobile phone to meet a lot of hardware conditions, to claim "VR ready", but certain conditions of the mobile phone, in the open like Youtube or VR games, such as VR applications, you can call VR Mode to Freeing up extra performance, more importantly, can shorten the delay and avoid the difference between motion and vision. All aspects of Android under VR Mode will be affected. The message from the sensor will be more frequent and given a higher priority; The original image cache will be output to the display of the image at once, and it will be changed to a direct output mode of a scan line. However, it is not understood that Burke mentioned that developers can access the "VR app-specific CPU core", but this seems to be no reason, it may be a forced core does not sleep mode? (Editor: May be a core of exclusive CPU) in any case, Samsung and Oculus have spent a lot of time to adjust the delay of Gear VR to 20ms, and Google provides this software-level VR mode seems to have the same effect, the Nexus 6P The delay in the Cardboard also dropped to 20ms, which was much better than the 100ms delay without VR mode. This also means that the same as the Nexus 6P mobile phone, you should start VR mode after the performance of the Gear VR class?

Hardware
Nexus mode =

In part of the VR hardware, we thought Google might launch a built-in processor and screen headset, but Google ended up with a headset that could fit into the phone (and look like a Gear VR), and a strip that looked like a rounded Apple Remote -Shaped remote control. A total of two keys on the remote control, and a circular touch zone, conceptually and Wiimote a bit like, the use of three-axis sensor in the VR world to operate. But it sounds as if Google is only giving a "suggestion" on hardware, and many of Google's partners are developing their own VR devices, and Google should also not be prepared to give hard-to-do rules on hardware.

When the Daydream platform was released, we wondered how Google could have just given a "reference design" instead of jumping off and making a template like a Nexus. In the end, Google announced that it will take the same strategy as the Nexus family on Daydream VR hardware, creating its own brand of Daydream VR headset for reference to other manufacturers. I just don't know who's going to work with him this time.

Of course, Daydream VR is technically a firmer (and better worn). Cardboard, or to be plugged into a mobile phone to use. Google is currently certification LG, Samsung, HTC, Xiaomi, Alcatel and other manufacturers of mobile phone equipment, the natural Nexus series will be able to and Daydream VR headset compatible with the device.

Content

Finally, with the hardware of course to have the content of the match. Daydream is also a platform to collect all VR content, except Google's own Street View, Youtube, photos, Play movies, and other services will have a special version for VR, Google Play will also have a VR zone, Put on a lot of support VR apps. CNN, columnist reported, Wall Street Journal, Netflix, HBO, and IMAX are now known to be listed. Naturally speaking of VR cannot mention the game, there are also EA and Ubisoft ready to be launched on daydream.
