Number One Game Designer

In Fang Xi's vision, it is best for the clothes of the VR suit to have feedback other than vibration feedback.

The most traditional game suit is vibration feedback, and vibration feedback technology games are one of the earliest fields of application:

As early as 1997, Lao Ren released a thing called a handle vibration bag, because their home machine N64 had been on sale for nearly a year at that time, but because of the application of new technologies at that time, Lao Ren could be called non-stop. This external device was released, and although the vibration bag was a bit bloated, it was widely acclaimed when it was released that year.

Because this thing can improve the feel of a game through touch, and the improvement is very obvious, so although this vibration bag is not particularly convenient to use, it is a cross-generation invention at that time, and the handles of later home consoles are basically. applied this technique. Until now, the latest gamepads on the market can not only vibrate, but also emit light and sound, and they can do more and more functions.

Or back to Hongyi, the vibration technology is undoubtedly the best and simple one, but it is not enough for the current VR equipment.

For example, the sensing suit that Fang Xi is wearing now, if vibration feedback is used, the advantage is that this will greatly save costs, but the disadvantage is that the vibration feedback is often relatively large and vague, and it is not as accurate as other feelings.

For example, if your character is hit by a bullet in the front of the game, then the feedback to the sensor suit should be a small area with a radius of no more than three centimeters to give you feedback, but according to the current technology, the player feels Most of the feedback I received would feel that I was hit by a 120mm mortar head-on.

Therefore, although the vibration feedback is cheap, the biggest problem is that it is not precise enough. At present, the VR studio is secretly guided by babbling. They are trying to make the possibility of replacing the vibrator with electrodes, and replace the imprecise vibration with weak current stimulation. feedback. But generally speaking, it will take some time for practical application.

According to the news Xiaoyi sent to Fang Xi, the experimental version of the electrode sensing suit that has been made so far is "like a bag of explosives" when worn, and the experimental version temporarily uses small lithium batteries connected in series, which is expensive and expensive. The safety performance that has not been verified is a problem. I also talked to Fang Xi about this:

【They tried to put that clothes on a monkey, the result, hahahaha】

"??" Maybe it was because he babbled for too long, but now that he is in the real world, he really likes to tease Fang Xi's appetite.

【Then that monkey fell in love with the feeling of being electrocuted, and was developed the shaking M attribute. Do you want to try it? 】

Fang Xi edited two text messages, then deleted them directly, and decided to ignore them. By the way, I thought about it in my mind and made this product a branch, such as fun...

After a minute, Fang Xi threw this idea out of his mind, let's leave it to someone who is destined to develop it. I am eager for the title of the father of video games, but I am not sensitive to the title of "father of shaking M props".

For this reason, the props that Fang Xi chose to experience this time are still the original vibration feedback sensor suits. The most important thing is to see how the core VR glasses are doing now.

Regarding VR glasses, Fang Xi had a basic misunderstanding before this: VR glasses are not just a mobile phone on a special frame, the real VR glasses are undoubtedly very close to human eyes like glasses .

Physiologically speaking, the principle of seeing things with the human eye is the same as the principle of small hole imaging, so there is a maximum viewing distance and a minimum viewing distance. The maximum is omitted, and the minimum viewing distance is about 10cm, that is to say, an object in Within 10cm of the human eye, it is impossible to image on the retina, so the most basic, such as in many spy movies and animations of elementary school students, it is theoretically difficult to directly transform the glasses worn into a display, because it violates the human eye. basic imaging principles.

So this is the difficulty of VR glasses,

If you do something like plugging in a mobile phone on the frame, you have to extend a distance of 10cm, but this distance will make the human eye feel very tired, and the redundant distance between the display and the human eye will also make people lose the sense of immersion.

So in the end, the VR department finally developed a special imaging technology under Fang Xi's suggestion and the guidance of the little death god. This technology is similar to 3D imaging. Solve and reassemble.

Therefore, the picture on the VR glasses will appear blurry like watching a 3D movie without wearing 3D glasses when it is 10cm away from the human eye, but the picture will become very clear when the lens is brought closer to within 10cm of the human eye. .

Sight distance, this is the first difficulty overcome by the VR department, and it is also the main content of Fang Xi's inspection.

According to the guidance of the person in charge, Fang Xi fixed the glasses on his head, and put forward his own opinions:

"Hmm... It would be great if the weight could be lighter, and I think the sponge in the middle can be replaced with a better one. It's best to make people forget that they wear glasses this time... Holy shit!"

What caught Fang Xi's eyes was a vivid underwater world, and the vision in his eyes was as if he saw it with his own eyes. There was no eye-catching black border around his line of sight to remind you that he was looking at the screen, and the last Importantly, this resolution is sufficient, exactly like what the human eye sees.

Fang Xi tried to stand up and take two steps, and then found that his gaze moved up a little. With the movement of his head, the world was displayed in front of him in 360 degrees.

Because it's still in the testing stage, Fang Xi didn't expect any VR games for him to play, so he asked the question he cared most about:

"How much do these glasses cost now?"

"This is a prototype, and the cost is around 120,000, but if it is to be mass-produced, the cost can be controlled at around 80,000."

Fang Xi pondered for a while, and then stretched his neck, which was weighed down by the glasses. I have to say that this is a bit too bulky as the first prototype. After weighing the weight, it is almost as heavy as a laptop, so this The glasses are actually similar to a helmet to prevent the weight from being unbalanced, but even so, it still makes Fang Xi's neck a little uncomfortable after wearing it for less than ten minutes.

"What about this weight? Can you reduce it a bit?"

The head of the smiling VR studio:

"Of course, this is what we are mainly doing now. In fact, the initial prototype helmet weighed nearly 20kg. We made an auxiliary bracket to ensure that the wearer would not break his neck. Now it has been reduced a lot gone."

"So Mr. Fang, how much do you want the glasses to weigh?"

Fang Xi looked at it and shrugged:

"Of course, in theory, you should try your best, but I guess a comfortable weight for people to wear should be... about 100g?"
