DIY four-point positioning light for virtual reality games

The decades-old PC and console games have evolved to date, and their 3D graphics, immersive sound effects and physical effects are becoming more realistic, with a view to increasing the player's sense of substitution in the game world. However, limited by the speed of hardware development, the feeling that the game brings to the player is always far from the real world.

Close your eyes and imagine that if we can feel the other things (virtual reality) and control the avatars (game characters) to interact, as described in the Cameron 3D movie "Avatar", the body does not move (reality equipment), What a wonderful thing!

The dream is not guilty, the creativity is the biggest, the magical technology house often goes against the sky, and it is learned that recently a domestic cattle "regeneration fairy" has designed a set of virtual reality game realization schemes with existing equipment and software, and made it yourself. . Let us see how he DIY:

In fact, the first day I saw Sony wearing a monitor, I was thinking about playing like this, but I have no time. Today, I finally took the time to finish this evaluation.

Presumably everyone will want to be able to hit the virtual reality through the head-mounted display. In fact, the virtual reality is not difficult. To put it bluntly, the picture is bound to the perspective of the head, where is the head, and the angle of view in the picture is also Where to turn, it is like being there. This can be achieved with the hands-on device I introduced today, paired with a Sony head-mounted display.

Introducing another product, the players in the simulation flight world must have a deep understanding of TracrIR. This is a head motion tracking device that can position the player's head through several positioning lights, thus in the game. Achieve the movement of the player's head to control the change in perspective in the game.

However, this device has a small audience and is very expensive. The domestic price is around 1,700 yuan.

A group of foreign players have used this principle to develop a software called FREE TRACK, which can achieve the same effect as TRACK IR through some devices that we can easily obtain.

The main device is " WII REMOTE ", which is the wireless handle of our common WII game console. It can process the captured infrared signal by itself instead of the CPU. It can greatly improve the fps, the refresh rate reaches 100hz, and it can accurately capture the movement of the head of the person (by infrared light).

Since the WII REMOTE is used as the motion receiver, all of the four positioning lamps need to be infrared light emitting diodes. There are a lot of things on Taobao, usually a few cents.

Since the resistor does not find 50 ohms, it uses two 100 ohm parallel soldering, which requires a total of four.

Infrared is invisible light, it can't be seen by the naked eye. It takes a camera to shoot it!

Next is the software debugging.

Connecting to WII REMOTE also requires a Bluetooth receiver, as well as a Bluetooth driver, I am using the BlueSoleil v6.4.249 version. When connecting WII REMOTE, press and hold the 1 and 2 buttons on the handle, then the blue light will start to flash. Then you can search for this device on the Bluetooth interface. Click “Search Service” and then “Connect Device”. (Do not pair match ~!) When the device turns green and uses the data flow indication, the connection is successful.

Then install FreeTrack, the software comes from FreeTrack official website

First select the four-point positioning hat mode in the Model, then select the intervention device in the Source of the CAM interface is Wii Remote

At this time, take the Sony head-mounted display + four-point positioning lamp that was fixed before, and the gimmick in the picture will start to move like your head movement.

Open a game, map the head movements to the perspective action, where to look at the head, where the perspective of the game turns, with the huge screen impact of Sony's head-mounted display, and a good 3D effect, so as to achieve an immersive game. Experience.
