Researchers have developed a sleep posture monitor that does not require the subject to wear sensors or mount a camera near their bed. This radio frequency-based system called the BodyCompass can be used to monitor someone while they sleep and provide insights into the progression of disease symptoms, health risks, and more. The system will be presented next week at the UbiComp 2020 conference.
While using technology to monitor movement and other activities while you sleep is not a new idea, many systems on the market are either intrusive, inaccurate, or both. BodyCompass, which was recently detailed by MIT Technology Review before his presentation next week is different; The system can be mounted on a wall where radio frequencies are used to monitor someone while they are sleeping.
The researchers behind the project find that certain health conditions may be linked to sleep risks such as epilepsy and the increased risk of death when sleeping in the stomach, as well as Parkinson̵
In addition to monitoring a patient to determine how often they sleep at night, including their shared posture, the system could also be combined with some sort of warning system to intervene if the patient is found to be asleep due to their existence in a dangerous position for health risks . Such a system could potentially also be used to monitor infants while they sleep and even as a wellness product to keep track of their own sleeping habits.
The team recently published a study on the technology that described a system that uses RF signals to determine the posture of the sleeper. To do this, the system maps the signals as they bounce off objects in the room and decodes them so that they can reveal details about the sleeper and ignore other objects.
