MIT researchers developed a new device that could track your sleeping pattern and give you the best positions. It can do this without the help of any camera or motion sensors.
Using the device, the researchers could identify the body's posture by mapping the signals' paths, which work backward from the reflections. However, scientists still need to identify which signals were bouncing off from the human body.
The device's developers discovered that the signals bouncing off a person's belly or chest are uniquely modulated by breathing. Once the researchers identify these signals, they could start analyzing the person's sleeping positions.
For example, if an individual is lying on her chest, the signals would be weak. But, if the sleeping person is lying on her back, the device would receive strong radio waves.
Yue explained that the individual's breathing serves as their coding to determine the body's signals and other objects. After the correct signals are received, a customized neural network will identify the body's angle while sleeping.
