Abstract
Technologies of contactless and real-time sleep tracking are described. One method of a sleep-monitoring device includes receiving radar data from a radar unit, the radar data representing a user's breathing. The method determines, using the radar data, sleep-stage data, presence data, and user identification data associated with the user. The method determines, using the i) sleep-stage data, ii) the presence data, and iii) the user identification data, a first event corresponding to sleep associated with the user and a second event corresponding to the sleep associated with the user, the second event occurring after the first event. The method modifies, using the presence data, the user identification data, the first event, and the second event, the sleep-stage data to obtain modified sleep-stage data. The method generates, using the modified sleep-stage data, a hypnogram of the sleep associated with the user.
