A team of MIT researchers has developed a device that can monitor people's sleep positions without the need to use cameras or stick sensors on their bodies.
It is a wall-mounted monitor, called the BodyCompass, and works by analyzing radio signals as it monitors objects in a room.
As the researchers explained, a device that can monitor sleep stations has many potential uses. It could be used to monitor the progression of Parkinson's disease, for example, because people with this condition lose their ability to go back to bed during sleep.
To differentiate between radio signals that receive from a body and signals that receive from random objects in a room, the system focuses on signals that receive from the chest and abdomen. to a person.
In other words, the parts of the body that move while the person is breathing. It then sends those signals to the cloud so that the BodyCompass system can analyze the user's position.
The team trained the neural network of creation and tested its accuracy by collecting 200 hours of sleep data from 26 subjects who had to wear sensors on their chests and breasts. belly at first. They said that after training the data device for a week, it predicted the correct position of the subject's body 94% of the time.
In the future, BodyCompass could be paired with other devices to stimulate a change of position, such as smart mattresses. When this happens, the device may warn people with epilepsy if they have a potentially fatal sleeping position, reduce sleep apnea events and notify caregivers to move patients. âºIi real estate. It could also help everyone sleep better, because we certainly all need it.
