Introduction: As a tool, VR can only exert its maximum value when it is applied in a reproducible application scenario and has complete business logic.
From 2014 to 2017, the popularity of VR has gradually increased. VR has evolved from a niche product in the technology circle and the geek circle to the market, becoming the darling of capital, the media, and the general public.
In the era of Internet technology, users are living in a variety of entertainment and application environments, and they are even more critical of the experiences and feelings that technology can bring. After the VR mobile phone box gradually withdrew from the stage, the desktop-class, home-based single, isolated VR experience began to no longer evoke the public's fresh desire. People's requirements for the interaction, social nature, and freedom of walking in the VR experience are gradually increasing.
From November 9 to November 11, the International Virtual Reality Innovation Conference kicked off at the Qingdao International Convention and Exhibition Center. This year's International Virtual Reality Innovation Conference takes the theme of "virtual and practical cooperation and win-win cooperation" as the theme and is sponsored by the Qingdao Municipal People's Government, the China Institute of Information and Communication Technology, the Virtual Reality Content Production Center, and the China Strategic Alliance for Virtual Reality and Visual Technology Innovation. Laoshan District People's Government undertakes.
Beijing Lightwell Technology Co., Ltd. (hereinafter referred to as ZVR) and Beijing Transmission Technology Co., Ltd. (hereinafter referred to as TPCAST) jointly released a large space wireless multiplayer interactive solution named "matrix" during this conference. "Matrix" is a VR large space multi-user interactive modular solution that can support 100 square meters. In this exhibition, both parties will provide users with a free-walking VR experience through the HTC Vive Headset and Wireless Kit.
ZVR's "matrix" solution uses an optical positioning system with a sub-millimeter-accuracy capture capability to capture the mark placed on the HTC Vive display through a high-speed motion capture camera to identify the trajectory of multiple players in space. Frees the player from a fixed position experience and realizes an immersive VR experience where multiple players naturally interact in a large space.
As we all know, HTC Vive head display uses a laser positioning method to provide the user with a room-level VR experience. This method scans the entire room through two lighthouses that work alternately, and combines inertial sensors to provide 6-freedom tracking information. Although this method can minimize the amount of space positioning calculation, but limited by the laser emission distance and accuracy, a pair of light towers can only track about 20 square meters of space. Although Valve has already disclosed a positioning scheme using 4 pairs of light towers in a 100 square meter range, the light towers that are used in time division multiplexing do not support the existing Vive heads, and the delivery time is still out of reach. ZVR currently offers a "matrix" solution that can expand the area based on existing VR heads and can now be installed.
For developers, the software system included in the ZVR "Matrix" solution has also been specifically optimized to help content development teams use the middleware "emerging space" based on the original VR heads-up without a large space-based positioning system. The system development content is directly adapted to a freely walkable multiplayer interactive environment. Moreover, the software system can be compatible with mainstream engines such as Unity and Unreal, and opens up restrictions between content production and content distribution platforms. Whether it is based on Oculus Rift or HTC Vive, users can easily adapt ZVR's large-space optical positioning solutions. Content developers can distribute games directly on the SteamVR platform for users to download experience. The optical system solution launched by ZVR at this exhibition shows the game "Wizard Magic (inVokeR)" on the SteamVR platform.
After continuous development, ZVR has solved a technical problem that has long plagued operators: Most hardware products are often incompatible with positioning systems. Currently, VR positioning systems on the market often need to update most products in the system in order to match new solutions. This kind of setting requires that the operator must upgrade the hardware product with the optimization of the plan. It is not friendly to the operator whether it is cost or efficiency.
In order to solve this situation, a platform-level product called "immediate space" has emerged. It is a product derived from ZVR's deepening of the subdivisional field of multiplayer space interaction. Its essence is a middleware. On the one hand, the content development team can pass the environment in the environment without a spatial positioning system, based on the original There are VR head-mounted system development content and are directly adaptable to freely walkable multiplayer interactive environments. On the other hand, through this system, the operator can realize the seamless connection between hardware and software: just open the software on the running computer, you can adapt different games to different peripherals, and even let Oculus Rift's games. Run on HTC Vive.
If new hardware is available, it can also be easily adapted by the software updating its adapter. In addition, based on the 60GHz wireless communication protocol, the software system can make any helmet become the display end of the PC-end transmitted image signal.
This means that future operators do not need to consider whether the hardware, content, and environment are adaptable. Instead, they will develop content more freely under a unified and universal system, and users will have more choices.
TPCAST: Multiplayer Space Wireless Dreams RealizedAs the only wireless VR solution provider in the world to realize productization, TPCAST ​​adopts stronger antenna design and optimizes hardware and software performance on the basis of the consumer version, and introduces a multi-user commercial version that effectively avoids mutual interference (hereinafter abbreviated as BE version). ).

A new rule from the Drug Enforcement Administration (DEA) threatens to upend the American hemp industry, and could even result in criminal prosecutions for manufacturers of CBD and delta-8 THC products.
The DEA says the [interim final rule," issued Aug. 20, is simply a matter of adjusting its own regulations to account for changes to the Controlled Substances Act that were mandated by the 2018 Farm Bill (or Agricultural Improvement Act) that legalized hemp and CBD production. The new rule [merely conforms DEA`s regulations to the statutory amendments to the CSA that have already taken effect," says the agency. The new rule doesn`t break any ground, according to the DEA.
But many experts on cannabis and hemp law say the DEA rule creates a potential pathway the law enforcement agency could use to prosecute hemp processors and producers of CBD (cannabidiol) and delta-8 THC (or Δ8THC) products. There are two issues: partially processed CBD, and [synthetically derived" delta-8 THC.
