Scientists create AI that can tell if you're dreaming

Scientists have created an algorithm that analyzes RF signals in order to monitor you in your sleep. It uses a device similar to a Wi-Fi router to determine everything from how shallow your breathing is to whether you're having a dream or not. The study was conducted by a group consisting of researchers from MIT and Massachusetts General Hospital's Division of Sleep Medicine. Imagine if your Wi-Fi router knows when you are dreaming, and can monitor whether you are having enough deep sleep, which is necessary for memory consolidation. Our vision is developing health sensors that will disappear into the background and capture physiological signals and important health metrics, without asking the user to change her behavior in any way. The sensor works by sending out low-level RF signals that bounce off of people.
