Chapter 1223 Projection keyboard?

"What's the second technology?" Boss Huang asked Tong He with great interest after disposing of Daqian Glasses.

"This is the infrared projection keyboard technology!" Tong He quickly introduced the next technology under development.

"Infrared projection keyboard? I remember that this technology doesn't seem to be a new technology. You have such a technology before the 21st century!" Boss Wang frowned and said, "And this technology is not suitable for terminals, so you can use this kind of thing. Fool me?".

The infrared projection keyboard is a technology that looks very awesome. It can project a keyboard on the desktop with infrared rays through a lens.

And users only need to put their fingers on the keyboard made of light, and then directly tap the desktop to input various characters and letters directly like typing on the keyboard, which is equivalent to creating a keyboard out of thin air with light. It is indeed visually stunning.

And to add such an infrared keyboard function, you only need to add a special projection bulb to the mobile phone terminal, which can be easily installed into a terminal, unlike the previous Daqian glasses technology, which also needs to cooperate with other auxiliary devices. The equipment is really strong in practicality.

It’s just that this seemingly awesome technology has actually been invented a long time ago. In the 80s, I had someone create a simple version of an infrared projection keyboard.

Because this keyboard technology essentially uses fingers to block infrared rays, allowing the terminal to recognize the input letters to complete the input. There is nothing too high-end in technology, and related samples are easily produced.

It's just that this kind of thing is easy to make, but it is very difficult to reduce it and most importantly improve the recognition accuracy.

After all, this is a technology that realizes input through infrared shielding. If you are not careful, it is easy to read wrongly, and then input wrong results.

Chinese characters are okay, but if you type in English, it is difficult to find spelling mistakes in words. A whole article will be typed out with typos, which is ridiculous.

In addition to improving the accuracy, the infrared projection keyboard also has a very fatal problem, that is, the keyboard must have the cooperation of the desktop, and there will be no feedback when typing on the desktop itself.

On the physical keyboard, many users dislike the lack of feedback of the keyboard, so they prefer mechanical keyboards that are crisper and have better feedback. A good mechanical keyboard can even sell for several thousand yuan.

But the infrared projection keyboard almost brings the feeling of using this keyboard back to its original state. After all, no matter who taps their fingers directly on the desktop, it will not feel very good.

The most important thing is that you have to have a desktop that allows you to put your hands down quietly. Most of the time when you use the terminal, you can't find such a suitable desktop.

To sum up, when Boss Huang heard Tong He introduce this technology to himself, he was very dissatisfied, because this technology is cool, but it is also very obvious that it is not practical.

Reminiscent of so many Android phones in the future, I would rather try my best to find a way to work hard on the screen-to-body ratio of the full screen. It takes a lot of hard work to compete for the 1% screen-to-body ratio. You might as well add a It looks like a very cool infrared projection keyboard.

"Boss, the infrared projection keyboard technology did come out decades ago, so we will definitely not use this technology to prove ourselves, and we don't have the face!" Tong He said with a smile, "This technology is one year old. The project was initiated before, but Mr. Zhao Chunlei, who is in charge of this project, is very capable. He immediately noticed the problems of this technology in practical application. So he put forward an idea to make this technology A small change."

"What change?" Boss Huang asked curiously.
"It's very simple, just change the infrared sensor technology to the infrared radar camera technology!" Tong He said.

"Outside radar camera technology?" Boss Huang was stunned for a moment. "Isn't this the technology that the research center is developing for our electric vehicles?"

That's right, Jiangnan Group is indeed developing electric vehicle technology at this time, and it has aimed at autonomous driving technology from the beginning.The core of the entire autonomous driving technology does not lie in AI, or the design of driving logic, but in how to control the entire road condition in real time.

Because designing the driving logic is actually not difficult, it is just a process of logical summarization and mechanical learning. With the level of programmers of Jiangnan Group, it only takes one year to come up with a complete program.

The most difficult part of the entire autonomous driving technology is actually data collection and a detailed grasp of the entire road condition.

The logic of the self-driving technology of electric vehicles is firstly to collect comprehensive road condition information, and then judge according to the road condition information, how to drive in the next step so as not to hit any objects, or not to violate traffic rules, and to accurately identify each vehicle. All kinds of traffic signs, etc., this is actually the real difficulty of the entire autonomous driving technology.

All kinds of car accidents related to autonomous driving technology that will appear in the future are basically caused by incomplete collection of road condition information.

For example, there was a car accident in the United States in which a self-driving Tesla directly hit the guardrail. According to the later investigation results, the reason was that it had rained before, causing water droplets to fall on the guardrail, causing light reflection, and this The reflection of the light caused the camera installed on the Tesla body to make a mistake in its judgment, thinking that the position was just a simple fog, and as a result, it rushed straight over, causing a serious car accident.

Later, there was a car accident in which a Tesla hit a little girl, and it was the same situation. The little girl was wearing a red and yellow dress, and the red and yellow clothes were separated from the top and bottom, and the separation was just at the shoulder. The location led Tesla to judge that the little girl was a safety cone on the side of the road.

And because there happened to be a car driving in the opposite direction from the opposite side at this time, Tesla's autopilot technology judged that it should turn left with all its strength, even if it would hit the safety cone... It must be compared with a collision between two cars Well, hitting a small safety cone isn't really much of a problem.

Then there was a car accident.

The above several car accident cases can fully prove that the core of self-driving technology to surpass the level of manual driving is to collect a large amount of road conditions and information, so as to make the most reasonable judgment for the computer.

At the beginning, the collection of road information was carried out with a high-definition camera. This camera will continuously take pictures of the road, and then the intelligent AI will analyze what each object in the picture represents, and finally obtain the corresponding road information. .

But what the high-definition camera captures is a flat picture after all, and no matter how high-definition the camera is, it cannot really be so high-definition.

It’s not that an electric car like Tesla can’t afford a higher-definition camera, but that the higher-definition the camera captures, the higher the pixel size of the picture or video, and the larger the file size. Such a huge amount of data requires a computer with more powerful computing power to be able to calculate it. Judging from the capabilities of the computing chips installed on electric vehicles, they are far from being able to calculate such a huge amount of data.

Therefore, under the instruction of Boss Huang, Jiangnan Group's electric vehicle automatic driving technology team directly abandoned the idea of ​​using a camera, and started the design idea of ​​the most advanced infrared radar camera in the industry.

Infrared radar camera, as the name suggests, is a device that combines the characteristics of infrared, radar, and camera.

The whole working process is like this, the camera first releases a large amount of infrared rays, these infrared rays can not only help the camera image, but also can continuously collide with the surrounding objects like a radar, and then form echoes one by one, returning to the camera’s receiving in the device.

By receiving the echoes, the receiver can obtain data on the position of a large number of objects around the car.

Because it is basically impossible to have military black technology such as stealth coating on the road, as long as radar technology is used, all solid objects are basically invisible, and their positions can be communicated to the computer chip immediately. , and then calculate the chip to plan the driving route.

On the other hand, infrared rays can shoot quite good-quality images. When the computing chip judges what the obstacle that the radar enters is based on the photos and videos taken, then it is the most reasonable form of judgment.

At the same time, when infrared rays are irradiated on the surface of objects of different colors, the infrared rays returned will have different changes. Through these changes, the actual color of each object can be directly judged, so that the car's ability to recognize traffic lights can reach its peak.

In general, as long as the infrared radar camera is successfully developed and installed on the electric vehicle, the electric vehicle can have a pair of eyes that are much sharper than the naked eye. Aside from some extreme cases, basically there will be no misjudgment of road conditions situation.

Therefore, the entire electric vehicle project team is doing its best to tackle this infrared radar camera technology at this time. Unexpectedly, this technology was taken over by the terminal project team.

"Yes, the data needed for autonomous driving is very accurate, so they are still polishing their infrared radar cameras. But our requirements are very simple, we only need to be able to recognize finger movements, so even if they research it The most basic version is enough for our project!" Zhao Chunlei said directly.
