At the end of last month, Google opened the door to developers for the Daydream mobile VR ecosystem. Now, Google has opened Daydream's door to the Web.
The tech giant today released a stable Chrome browser supporting WebVR for Daydream mobile phones and headsets. This also means that when browsing to a WebVR-compatible page, you can insert your phone into Daydream View and view the content in VR, whether it be a 360-degree video or a complete virtual reality experience.

No need to download anything to access these experiences, they provide a quick way to enter VR as easy as surfing the web. It's like you can directly access 360 YouTube videos without using the Daydream app.
To celebrate the release, Google has provided some of the best WebVR content you have found so far. Examples include Bear 71's interactive VR documentary, Matterport's 360 photo and video library, Within's 360 movie, and Sketchfab's user-created models. Interestingly, in Playcanvas's WebVR Lab experience, Daydream's controller can be used to play.
WebVR has been integrated with Chrome for a long time, but it hasn't really been completed yet. The version that supports Cardboard and integrates into more mobile phones will come soon, however, Chrome's application on Windows is still only experimentally supporting WebVR.
Google is not the only company that currently promotes WebVR. Samsung is also using Gear VR's browser to support WebVR's API. Oculus is also using its own browser, code-named Carmel, to support WebVR. It will run on Gear VR and Rift. Although it still needs years of development, eventually WebVR should become a widely used feature of many browsers and headlines. Last month, we also reported on Google’s own new tool that will help optimize VR on the web.
In general, ONU devices can be classified according to multiple application scenarios such as SFU, HGU, SBU, MDU, and MTU.
1. SFU type ONU deployment
The advantage of this deployment method is that the network resources are relatively abundant, and it is suitable for independent households in the FTTH scenario. It can ensure that the user terminal has broadband access functions, but does not involve more complicated home gateway functions. The SFU in this environment has two common forms: it provides both an Ethernet interface and a POTS interface; it only provides an Ethernet interface. It should be noted that SFU can provide coaxial cable functions in both forms to facilitate the realization of CATV services, and it can also be used with home gateways to facilitate the provision of value-added service functions. This scenario is also applicable to enterprises that do not need to exchange TDM data.
2. HGU type ONU deployment
The HGU type ONU terminal deployment strategy is similar to the SFU type, except that the functions of the ONU and RG are integrated in hardware. Compared with SFU, it can realize more complicated control and management functions. The U-shaped interface in this deployment scenario is built into the physical device and does not provide an interface. If you need to provide an xDSLRG device, you can directly connect multiple types of interfaces to the home network, which is equivalent to a home gateway with an EPON upstream interface. Used in FTTH occasions.
3. SBU type ONU deployment
This deployment scheme is more suitable for independent enterprise users to construct the network under the FTTO application mode, and is based on the enterprise change of SFU and HGU deployment scenarios. The network in this deployment environment can support broadband access terminal functions and provide users with multiple data interfaces including El interface, Ethernet interface, and POTS interface, which can meet the needs of enterprises in data communication, voice communication, and TDM dedicated line services. Usage requirements. The u-type interface in the environment can provide enterprises with a frame structure with multiple attributes, which is more powerful.
4. MDU type ONU deployment
This deployment scheme is suitable for multi-user network construction under multi-application modes such as FTTC, FTTN, FTTCab, and FTTZ. If enterprise-level users have no demand for TDM services, this solution can also be used for EPON network deployment. This deployment solution can provide broadband data communication services for multiple users, including Ethernet/IP services, VoIP services, and CATV services and other multi-service modes, with powerful data transmission capabilities. Each of its communication ports can correspond to a network user, so in comparison, its network utilization rate is higher.
5. MTU-type ONU deployment
The deployment plan is based on the commercialization of the MDU deployment plan. It can provide multi-enterprise users with multiple interface services including Ethernet interfaces and POTS interfaces, and can meet enterprise voice, data, TDM private line services and other services demand. If combined with the slot type implementation structure, richer and more powerful business functions can be realized.
