MIT's new algorithm locks sleep poses using radio signals

An MIT research team has developed a device that can record people's postures while they sleep without

the need to use cameras or stickbody sensors. This is a BodyCompass wall monitor that analyzes radio signals that bounce off objects in the room into the device. As the researchers explained, BodyCompass can control postures. It can be mainly used for medical purposes.

To distinguish radio signals bouncing offbody, from signals bouncing off random objects in the room, the system focuses on impulses from a person's chest and abdomen - parts of the body that move during breathing. It then sends these signals to the cloud so that BodyCompass can analyze the user's position.

The new gloves imitate touch. They work even thousands of kilometers from each other.

The team trained and tested the neural networkaccuracy, collecting 200-hour sleep data from 26 subjects who initially had to wear sensors on their chest and abdomen. The researchers noted that after a week of testing, the device correctly indicated the subject's body position 84% of the time.

In the future, BodyCompass can be combined withother appliances, such as smart mattresses. When this happens, the device will reduce the incidence of sleep apnea and notify caregivers when patients are moving at risk of injury. The device will also tell in which position users get better sleep.
