Everything is finally in place, and the installers have long since left. Pen? Interesting? Pavilion wWw. ｂiquge。 info I put on my gear suit and went into VR100.

Where to go first? "Dominating the world"? Or "Arena". I followed the instructions to make gestures (most of which are the same as data gloves) and brought up the floating menu. I found that the test item in N City was also in it. Pull it up and try it. I played it back and forth seven times, but not once did I beat my score at that time. It seems that I can't save this indifferent princess. Forget it, I'm disappointed.

I entered the chat room of the Drifting Snow forum. The scene seen is no different from what it was in the helmet. But for some reason, I always feel that the 3D effect here is more realistic, and it doesn't feel abrupt at all. And no matter how long you use it, you don't feel dizzy. Is it because of the difference in resolution and refresh rate? Or is it the reason for the increased sensation? It doesn't seem to be.

I saw the Tianshan Snow Lotus dressed in white. "You're in VR100 now! How does it feel? She asked.

"It feels good." I said, "Eh, Sister Xuelian, why does what you see in it feel more real than inside the data helmet and there is no dizziness?" ”

"Oh, that's because of the eye-tracking focus technology."

"What tracking technology?"

"It's gaze-tracking focusing technology." "For example, the 3D movies we usually watch. Its three-dimensional perception is generated by binocular parallax. You know this, right? ”

"I know."

She continued, "But the two objects are still on the screen, which means that the focal length is still the distance from the eye to the screen." However, the human binocular viewpoint and focal length are originally synchronized. When the point of view does not align with the focal length, vertigo and eye fatigue occur. And there is a problem with 3D movies. You know that lenses have depth of field, right? ”

"Hmmm! I know. ”

"When a film is being shot, the focal length of the lens is definitely on the main character in the current scene. But it's possible that you're looking at another object at this time, and it's entirely possible that this object is outside of the depth of field. This creates another kind of discomfort. ”

"I seem to get it. Is it true that in VR100, the image I see is not two different images projected on the same plane, but a 3D image that exists in the space in front of me? "I think that's the only way it makes sense.

"It's not. True 3D spatial imagery is now only possible with laser holograms. With the current level of technology, it is far from achieving real results. She continues, "Gaze-tracking focuses detect the intersection of the binocular gaze in real time and adjust the lenses in front of the eye accordingly so that the image is exactly at the distance from the intersection. At the same time, the depth of field is set according to this distance, and the bokeh of out-of-focus images is performed. ”

"Isn't the image out of focus still imaginary, and the focal length is wrong?"

"Because the focus of the human eye is on the macula in the center of the retina. There is no obvious sense of whether the objects other than the macula are in correct focus. The main thing is that its line of sight intersection and focus point change synchronously, so there is no feeling of vertigo and eye fatigue. ”

I seemed to understand what she said. But it still feels a little strange that such a large number of technical terms are spoken in a soft voice by such a beautiful girl. If I had done the same in my physics class, my grades would have been much better.

"Sister Xuelian, will you go to the arena today?"

"No, and I won't be going during this time."

"Why?"

"I have something else to do now. Now the Fire Phoenix is over there. Go find her! ”

"Sister Xuelian, I have one more question."

"What?"

"In VR100, how did the tactile sensation of the body and the impact on it come about? In the process, my equipment didn't touch any outside objects! ”

"Well, I'm going offline soon. I'll explain it to you another day! You can also go into the arena to find the Fire Phoenix and ask her to explain it to you. After speaking, I saw her image slowly fade, and finally turned into a silhouette.

Press the button to enter the arena. In front of me, a slightly European-style corridor leading to the arena appeared. Walking around the corner, a tall figure with red hair and red clothes appeared at the end of the hallway. Isn't this a fire phoenix who? However, unlike what I had seen before, she was wearing a full-length jumpsuit instead of a short skirt, and her legs were not showing an inch.

"Welcome to the VR Arena." She said, "Come, shake hands!" ”

Our hands are clasped together. I immediately felt the strength of her hand, and then added a little more force. She shook off my hand, "What are you doing with so much energy?" ”

"You worked hard first!"

"I'm a woman, shouldn't you let me have some."

"Then I'm still a little brother!"

She smiled and began to look me up and down, "This image of yours ......"

"What, what's wrong?" I asked.

"It's a little bit different from you! Is your face so angular? ”

"A little beautified."

"I don't think it's better than you."

"How do you know what I look like?"

"There's a video recording!"

"I haven't videotaped with you!"

"Didn't I have a video without me?"

"It's not fair, I don't know what you look like yet."

"I'm like what you see."

"Really? I thought there wasn't a girl in the world who looked so pretty! ”

"Oh! Thank you for the compliment. ”

"Sister, how tall are you?"

"1.72m, what about you?"

"Two centimeters taller than you!"

"Really? How do I feel shorter than me? ”

I looked at her feet and said, "You're wearing high-heeled leather boots!" ”

"Oh!"

"Huh? Sister, are your legs really that long? ”

"It's the true proportions of my body. Your image is good, is it true? ”

"Well, almost."

"Come on, now follow me to Arena 9. I'll accompany you to do adaptive swordsmanship training. Then he turned and walked forward.

Swordsmanship training is exactly what I wanted. I followed behind her, listening to her clattering footsteps. She walks quite beautifully. It's just that the beautiful legs that have been exposed all the time are hidden in the leggings, which makes me feel a little uncomfortable. I wanted to ask her why she didn't wear a short skirt anymore, but she never asked.

Walking past the next turn, her body suddenly went short. Luckily, I was quick to react and didn't trip over her. "Hey, why are you still carrying a sneak attack?"

"Boy, you're quick to react!"

There are a total of 12 arenas in the arena, and there is basically no difference in the layout (it must be using the same set of data models), but the size is somewhat different. Arena 9 is the smaller one.

Phoenix took the sword from the shelf and handed it to me. I took it and immediately felt a heavy pressure on my hands. "This sword is so heavy!"

"Haven't you practiced swords in the martial arts team?"

"That's a lot lighter than that."

In the ensuing matchup, I was stabbed in the chest twice by a phoenix and wiped my neck once, which was simply embarrassing. She kept looking at me with a smile, "Come again!" ”

It took me a lot of encounters before I got used to her routine. "Yes, it's making rapid progress!"

"Sister Phoenix, what kind of swordsmanship is this?"

"Well, my teacher created it. We call it the Flying Snow Thirteen. It integrates Western swordsmanship into Chinese martial arts, so it focuses more on actual combat. ”

"Okay, I remember!"
