As long as you talk about health, blood pressure, respiration, body temperature, pulse and other issues, people will think of wearable trackers, which is a good way to early find physical problems and prevent diseases. For those who do not have time to go to a large hospital to check their physical condition, it is very convenient!
Recently, researchers from the Computer Science and Artificial Intelligence Laboratory at the Massachusetts Institute of Technology proposed a non-intrusive and non-wearing method to effectively monitor people's physical condition in real time. They named the initial product WiGait. The principle is to use wireless signals to detect the pace of humans in order to determine the health of humans.
Today, many devices such as wristbands, watches, and mobile phones have GPS capabilities. Although this feature can be used to detect and calculate the number of steps, this calculation is often not as accurate. Radio signals can be affected indoors or with obstacles.
So, since it is not a wearable device, what is WiGait?
WiGait is actually a very special "wireless router", not because it has a beautiful appearance, or complex features. On the contrary, it looks very ordinary, like a white plastic board hung on the wall.
What is special about it is that WiGait will detect people's indoor activities through wireless signals and judge in advance the health problems that people may produce. For elderly people who are at home, they are always aware of their physical condition or remotely send out alerts in an emergency. It is very necessary for other family members.
The wall-mounted wireless Wi-Fi router emits a low-power wireless signal that emits electromagnetic waves like a smartphone, and this electromagnetic radiation accounts for only one percent of the mobile phone's output.
By analyzing how these signals rebound when people walk, to detect the speed of walking and the size of the pace, it can be predicted whether the body has an adverse situation.
Researchers at the Massachusetts Institute of Technology claimed that WiGait can accurately measure people's speed and pace at least 85% of the time. It can also collect data from multiple people at the same time and label each person to intelligently manage the health status of family members.
Professor Dina Katabi told Fastcodesign: “Now that you have a smoke detector installed at home, you don’t have a health detector. You need that kind of thing, and it’s very important.â€
For detecting health problems, WiGait products have a greater role for the elderly.
When people reach a certain age, it is inevitable that there will be diseases such as Parkinson's disease and even Alzheimer's disease, leading to obstacles when the patient (elderly) walks.
Parkinson's disease (PD) is a chronic central nervous system degenerative disease that affects people's motor nervous system. Its symptoms usually appear slowly over time. The most obvious early symptoms are tremors, stiff limbs, impaired motor function and abnormal gait, and finally affect cognitive and behavioral problems.
Alzheimer's disease, or Alzheimer's disease. It is a fatal neurodegenerative disease that can easily be triggered by the growth of a person. In most cases, the old man will not “realize†himself that he is already sick.
In order to solve the above-mentioned diseases that the elderly people may cause, doctors usually test with a stopwatch in hand to see if the patient walks, or if the patient has a detector to measure if he has a stroke. However, sometimes the patient will develop in an unpredictable environment and may even be at risk.
And this piece of white WiGait radio wave board can be installed separately in any corner of the house, so that users can "early" know their physical condition.
If you play a fierce ball game from outside today, accidentally sprain or hurt your bones. When you come home and walk with a limp, the humble white version can automatically detect where your body is having problems.
In addition, for some busy office workers, they do not have time to go to a large hospital to check their physical condition, they can't find small injuries, and if they do so for a long time, they will delay their health.
Even WiGait is suitable for nursing homes. Doctors or nurses do not need to take papers and pens every day to manually count the speed and pace of their walking. It can be used to monitor how elderly patients move and how the patient's body changes over time. The main point is that it can also dynamically detect the recovery of patients after medication or physical therapy.
For users, they do not need to wear "annoying" health detectors every night, or synchronize to mobile devices. Although WiGait does not have any sense of existence, it can help you to predict the diseases you may get in the future.
