Description

3D PC room equipment for wireless network equipped with stationary HMD chair {THE APPARATUS OF 3D-PC ROOM WITH HEAD MOUNTED DISPLAY}

The present invention relates to a wireless network-only 3D PC room facility device equipped with a stationary HMD chair.

HMD (Head Mounted Display) equipment has been developed and researched since the 1970s, and high-end, low-cost equipment is being produced and marketed.

HMD is a first-person display that replaces existing LCD monitors and realizes 2D and 3D large screens in virtual reality.

However, the HMD sold as a portable type is a glasses type or a helmet type, but is willing to move, but side effects are lost by wearing it like glasses or wearing it on the head like a helmet. For example, wearing a portable HMD causes symptoms such as dizziness, headache, and nausea. This causes a feeling of rejection by the user.

It also warns of mental and physical fatigue from immersion.

In addition, PC peripherals are generally designed to be connected to a PC by wire, which disturbs the periphery of the PC user's PC desk. Devices that require a separate power supply will require dedicated adapters and multi-taps. This is a method of connecting a peripheral device to a peripheral device by separately supplying a low power conversion adapter to a standard 220V outlet. This is dangerous because many wires are cluttered around the PC. In addition, the multi-tap that connects many adapters has adapters for supplying power to peripheral devices other than PC dedicated power, so if one adapter fails or the multi-step fails due to electric shock on the adapter due to the peripheral device failure, It may interfere with the use of a PC.

Many PC stores, such as PC rooms, use LAN lines to connect the Internet to their PCs.

This has caused the inconvenience of having to construct a facility to extend a LAN line to a store by an Internet provider, and to perform a new construction when replacing or expanding a LAN line due to a defective LAN line.

Therefore, the existing PC room facilities are connected only by wires, causing a lot of safety problems that the user trips over to computer peripherals. Even if a 3D dedicated HMD is installed, dizziness, headache, and nausea symptoms appearing in glasses or a helmet type Therefore, there is a problem of reluctant to use the HMD, it is urgent to develop a technology that can cope with this.
