A system called Marko uses signal reflections to provide scientists and caregivers with valuable insights into people's behavior and health. Marko transmits a low-power radio-frequency (RF) signal into an environment. The signal will return to the system with certain changes if it has bounced off a moving human. Novel algorithms then analyze those changed reflections and associate them with specific individuals. The system then traces each individual's movement around a digital floorplan. Matching these movement patterns with other data can provide insights about how people interact with each other and the environment.
