If the market has only smartphones and tablets, it is not enough. Apple, Samsung, Google and other giants have long been rumored that they will strive to bring in new "wear-resistant" technology products in the future. As we all know, Google's smart glasses have been sold on the market. Although only for a small number of people, the glasses are connected to a smart phone via Bluetooth, the premise is that the application you need must be installed on your smart phone, and then you You can choose your own function in the glasses, you can send any information to your watch, such as call alerts, SMS, Google Talk messages, Facebook messages and so on, and your smart phone can still answer calls or reply messages . In addition, there is Apple's IWATCH, which is a wearable device that can connect with your iPhone or iPad. Wearable technology may be something for the future. It's a great project. When you want to track distance, time, heartbeat, etc., you can work with your watch on your wrist. If the market is a bottomless pit, then there is no end to the technology.
