Most of us use smart phones now, and some of us may have smart watches. They are very common to see. But how about smart glasses? Have you heard about them?
It's said that before the end of 2021, the companies Apple, Facebook and Google will join Amazon in making smart glasses come to the market. Smart glasses, also called AR(augmented reality) glasses, will help AR become a part of our daily life.
Unlike VR (virtual reality), AR is about the real world. It tells us more about our real-world activities by showing computer generatedinformation in front of our eyes. For example, when we plan to buy a new sofa on the Internet, with a pair of AR glasses, we can "move" it from the Internet to our living room to see whether it is the one we need.
AR glasses just look like the glasses that we usually wear. They use a front facing camera connected with software. They not only put pictures on the glasses but also can help us "see" information such as how fast we walk or run, where we are, and biometric data. This will help doctors, coaches and teachers get all kinds of usefulreal-time data about patients, sportsmen and students.
AR glasses will free up our hands and sore necks because we don't need to look down at our smart phones for information. Let's wait and try.
