The next step for

science and Technology Daily - wearable devices are increasingly fiery. But imagine, do not need to wear any special facilities, there is a kind of technology can not touch your body will detect your vital signs, even in the next room "wall" to finish all this, is that possible? But now, in the American Massachusetts Institute of Technology (MIT) wireless Center Laboratory of computer science and artificial intelligence, researchers are the fantastic scene into reality. But some people worry that, this technology will develop to even the camera does not need, just some privacy?

according to the official website of Massachusetts Institute of Technology in June 15th published the news, researchers have developed a new wireless system, through the WiFi network "perspective" to track the closed room or on the other side of the wall motion. The latest report shows that, the system can partition monitoring to like thoracoabdominal and subtle movements, and researchers can with 99% accuracy judgment be detected rate. The signal current to track the heart beating 4 people at the same time.

has been tracking the human body, very difficult to realize the real-time heart rate. But now he can lower cost technology to complete it. This technique makes use of Everton Jerseys Cheap the wireless signal is a low power, through the walls, to monitor the signal back to the time, according to the change of the reflected signal, researchers can observe the movement of the human body. The monitoring of human heart rate according to the fluctuation of the human chest, accuracy rate as high as 99%.

The

researchers said, compared with the technology of radar and sonar and other existing "perspective" Cheap AC Milan Jerseys technology, advantages of low cost, low energy consumption, size mini. It can be widely used in handheld devices, can also apply to military requirements; its development will provide academic research and development process of disaster rescue in human body tracking, open a new path; and it is convenient for users to track their health data at any time; at the same time, also can use this technology to develop a simple signal, to ensure the perfect monitoring elderly relatives in various environments or baby -- people can be observed in the elderly or children Cheap Tottenham Hotspur Jerseys living in another room in the action of the heart rate, without requiring them to wear any complex wearable devices.

The next step for

, researchers interested in the technology function is extended to the higher resolution, for example, to identify the body contour, or in pursuit of human emotion, and the monitoring Cheap Germany Soccer Jerseys will be through the will and heart rate and respiration as strong index of sentiment.

however, expressed concern about the existing sound, when the technique to the development of high resolution, Cheap Brazil Soccer Jerseys will raise privacy issues.
