Abstract
The present invention discloses a method and an apparatus for precisely perceiving an indoor activity. The method may include: receiving a vibration signal on a floor by using multiple vibration sensors disposed according to a preset rule; and determining a location of a vibration source according to a phase difference of a vibration signal of the same vibration source in different vibration sensors. The monitoring performed on the indoor activity in the present invention can be performed without disturbing the monitored person, and can resolve the concern about leakage of privacy of the monitored person.
