Inventory of wearable smart devices

As a technological development trend, wearable devices will become an inseparable part of our lives sooner or later, because they represent the future. However, it is also like a sword of Damocles hanging over our heads. While it brings us convenience, it also brings some threats and uneasiness. But we don’t need to be pessimistic. Just like when mobile phones first added camera functions, it also caused a big discussion about privacy. But today, the camera level of smartphones is already part of the continuous improvement of mobile phone manufacturers. . So the problem is not the technology itself, but the people who use it. How to effectively use technology to change life, and how technology can bring us maximum convenience is the ultimate goal of these wearable devices.

No. 1 on the list: Google Glass

Google Glass is essentially a combination of micro projector + camera + sensor + storage transmission + control device. It can integrate glasses, smartphones, and cameras into one, and use computerized lenses to display information in front of the user in real time in the format of a smartphone. In addition, it is also a life assistant, which can provide us with functions such as GPS navigation, sending and receiving text messages, photography, and web browsing.

Its working principle is actually very simple. The micro projector in the glasses first projects the light onto a reflective screen, and then refracts it to the human eyeball through a convex lens to achieve the so-called "first-level amplification" and form a large enough image in front of the human eye. A virtual screen that can display simple text information and various data. So Google Glass looks like a wearable smartphone that can help us take photos, videos, and make calls without having to take out the phone from our pocket.

No. 2 on the list: Apple iWatch

If you think the current Google Glass looks a bit different when worn, you might as well look at wrist-mounted devices like the Apple Watch, which look easier for us to accept.

Not long ago, news broke that Apple is developing a new generation of iOS watches-iWatch. This device uses a curved glass design that can be flat or curved. It has a communication module inside that allows users to complete a variety of tasks, including adjusting playlists, viewing recent call records, and replying to text messages. Of course, it uses our own iOS system internally.

Just as the iPhone redefined mobile phones, the iPad ushered in the era of tablet computers. iWatch is considered likely to be Apple's next disruptive product. However, some analysts pointed out that iWatch will not replace the iPhone, but more of a supplement to the iPhone and expand the functions of other devices, making it more convenient for users to use Apple devices. For example, when the user doesn't know where your phone is, you can use the iWatch's Siri function to make the iPhone sound and vibrate to help the user find the phone smoothly.
