According to news, on the 18th, Google launched a modified version of Android mobile operating system for wearable devices - Android Wear. Similar to Google Glass, Android Wear will be based on Google Now, Google’s speech recognition technology. It also has some additional fitness tracking applications built in. The product is designed to be positioned on wearable devices, and the initial design will target smart watches.

In the 1960s, wearable technology first appeared in the MIT Media Lab in the United States. This technology can be used to embed multimedia, sensors, and wireless communication technologies in people’s clothing. It can support gestures and eye movements. interactive mode.

A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. The wearable device is not only a hardware device, but also implements powerful functions through software support, data interaction, and cloud interaction. The wearable device will bring about a great change in our life and perception.

Some existing wearable devices:

Google Glass: On June 28, 2012, Google released this wearable IT product through an I/O product launch event. With all the functions of mainstream smart phones, communication and data services are readily available. A miniature display on the right eye side, a 720p video camera placed parallel to the outside of the right eye, a touchpad placed on the temple, and a speaker, microphone, gyro sensor, and built-in battery that can support 6 hours of electricity.

Glasses Display: Apple's patented abstract description of the wearable IT device shows that the technology will use one or two displays to project images into the user's eyes. Normally, such displays do not play back images to the user's peripheral vision, and Apple’s patented technology takes a new approach so that the images played by the monitor will not only enter the user's line of sight, but also “guide” the user's line of sight. .

Apple Iwatch: iWatch, a smart watch designed by the concept designer Anders Kjellberg. This watch has an iOS built-in and supports Facetime, WiFi, Bluetooth, Airplay, etc. At the same time, the most surprising thing is that iWatch supports Retina touch screen.

BrainLink idea headband is an accessory product developed by Shenzhen Macro Intelligence Technology Co., Ltd. for iOS system. It is a safe and reliable head-worn brainwave sensor that is easy to wear. As a wearable device, it can wirelessly connect to terminals such as smartphones, tablets, laptops, desktop computers, or smart TVs. With the corresponding application software, you can achieve interactive control of mind and thought.

Problems exist:

1, the price is expensive. Google Glass is priced at US$1,500; Nike+FuelBand SE is priced at US$149; Adidas’s upcoming Android smartwatch is priced at US$399.

2, battery life is short. The battery life of ordinary smart watches is around 24 hours. If more functions are enabled, the power consumption will increase, and the user will have to charge twice a day for normal use.

3, can not be used independently or incomplete. Many smart watch features require the use of a mobile phone to use it. Consumers can't help but ask: What else can you do with it?
