Lenovo New Glass has been exposed, but no one has been so close to CES2015. At the time of the sale of Google Glass, the price of a treasure of over 10,000 yuan made many geekers stunned. One was too expensive, and the other was that google service was difficult to serve users in China. So, when Lenovo launched a New Glass, it was exciting.
Previously, there have been rumors about Lenovo smart glasses on the Internet. The rumor described the smart glasses using bone conduction technology and supporting private calls. Today, New Glass finally appeared at CES2015, which was jointly developed by Lenovo and Yunshi Zhitong and launched for the general consumer. It uses a host, battery and optical head separation design to achieve a load of more than 800 mAh while achieving a lens load of only 15 grams. At the same time, New Glass supports a variety of control methods such as voice control, trackpad control, and ring control.
Next, let's take a look at New Glass.
Do not pick the frame of New Glass
The biggest advantage of New Glass is not that it has more features than Google Glass, nor is it much more technological than Google Glass, but a very simple feature that fits the user's own glasses.
The other frame is also adapted
The principle of implementation is very simple. There is a small clip on the body of New Glass. It can hold the frame of the user tightly, and there will be no looseness in normal life activities. It is no longer afraid to see Glass. I can't see people.

Not only does it have the ability to adapt to a variety of eyeglass frames, New Glass also features a high-definition camera with an 800w pixel camera capable of capturing 1080p HD images and recording everything around you. The lithium battery of up to 1388mAh allows users to record and photograph for a long time and share it with social media, so that friends can share your happiness. The voice control function allows you to make calls, etc. by voice, without having to get started.
New Glass calculation and display section
Unlike Google Glass, New Glass is a split mode, in which the calculation part is connected to the battery component, the battery pack is hung around the neck, and the overall weight is reduced, so that the glasses do not cause nasal discomfort due to the inclusion of New Glass.
Battery pack section
The battery pack can be placed around the neck like a collar without increasing the burden on the head.

The middle part of the calculation part is where the clip is located, and its strength is still sufficient.
Display section
Display principle
The display part of New Glass is far from simple, just a simple optical problem. Things are very close to your eyes, you can't focus, of course you can't see clearly.
Even if something is far from your eyes, your eyes can focus on it, but you will not see anything further away. At this time, if you want to walk, would you hit the wall?
You try the pattern on the glass window. When you see the pattern, you can't see anything in the distance. When you look at things in the distance, the patterns on the glass are naturally invisible.
Therefore, the most subtle part of New Glass is: When you look at the distance, you can see the image on the glasses.
The principle is actually very simple. In terms, it is to image the image on the glasses to infinity.
The solution is also simple: put the image on the focus of the convex lens (magnifying glass), and you look at the other end, it is at infinity. This is secondary school physics, and the light emitted from the focus becomes parallel light after passing through the convex lens. The focus of the parallel light is at infinity.
However, you can't see the convex lens on New Glass. Indeed, it does not have a glass lens that bulges on both sides. Most of it uses a Fresnel lens, a flat lens, but it can be equivalent to a convex lens that bulges on both sides. This simply solves the problem of the display part.
3.5mm headphone jack
Since the author did not try it on, it is not good to judge whether New Glass supports bone conduction earphone technology, but it seems that it should only support 3.5mm headphones for playback.
Principle of bone conduction
I forgot that in high school or junior high school, we also learned that the transmission of sound requires media. This medium can be not only air, but also metal, water, stone, and of course its own bones are no problem.
In general, the sound we hear is transmitted from the air to the ear, then passed through the auditory nerve to the brain for analysis, and finally the sound is heard. The way the bone conduction earphones are different is that it transmits the sound to the auditory nerve through the vibration of the cheeks on the cheeks, and finally the sound is obtained through the analysis of the brain. That is to say, even if we don't have ears, we can still hear the sound.
When we usually eat, the sound is very small, and the people around us can't hear it, but we listen very clearly. Even if you plug the ear with something, the sound is still very clear. This is also bone conduction.
It was alleged that when Beethoven’s ears were not working, he heard the sound by biting a stick connected to the baton. The sound of the piano was transmitted through the stick to Beethoven’s teeth, and the bones were transmitted to Beethoven’s auditory nerve. Of course, this method of listening to the sound is quite backward, and it is not good to bite things and even talk.
However, since the density of the bone is much larger than that of the air, a large amount of energy is consumed in the conduction process, so the AfterShokz bone conduction earphone exhibited on the CES requires an additional battery case.
In addition, the biggest problem with bone conduction headphones is that there are often resonance peaks in the low frequency or high frequency, which will greatly affect the sound quality, which is why many people say that this type of headphones does not have heavy bass.

800w camera, in fact, can do a lot of things, camera video is not a problem, just do not know the situation of long-term video, how hot, this is also the author's concern.

In real life, our hands are already very busy, so the smart hardware products designed by the manufacturers will be the products that can completely liberate the hands, and the smart glasses are the best choice. New Glass operates through voice, gestures, etc. Can make our hands fully liberated.
New Glass adopts a frame-grip design, so users don't have to give up their original glasses to meet the individual needs of the user. New Glass also adopts a separate design of the host to design the battery in the neck. The position increases the standby time and makes the host worn on the head lighter.
WS2811 digital led strip is single signal transmission Led, the same as WS2812B and SK6812 with three-channel circuit,
But It is difference,the WS2811 IC can be inside or outside. and the working Voltage is DC5-24V, can be program and apply to all kinds of electronic products, electrical equipment running horse lamp, led pixel screen etc.
It is the most common product and demand on the market.
