US 2022/0101709 A1 · INDOOR OCCUPANCY ESTIMATION, TRAJECTORY TRACKING and EVENT MONITORING AND TRACKING SYSTEM

Abstract

The present disclosure relates to a monitoring system configured to monitor the activities of individuals without having to keep the surrounding area under the surveillance of a camera thereby maintaining the privacy of the individual. In particular, the monitoring system includes a network of sensitive sensor units that are installed onto indoor flooring to record human footstep induced vibrations. The data collected from the sensors can then be processed to identify individual occupants, determine the number of occupants, estimate the location of footsteps, and track the trajectory of each occupant. The extracted trajectory information can be used to assess an occupant's personal activity and social interaction, which can then be used to analyze the individual's physical and psychological health.

Dependent claims

A monitoring system for monitoring activity in a predefined area, comprising:

a network of sensor units arranged on a floor of the predefined area, individual sensor units of the network of sensor units comprising:
a sensor;
a computing device in data communication with the sensor;
and
at least one application executable in the computing device, wherein, when executed, the at least one application causes the computing device to at least:
receive sensor data from the sensor, the sensor data comprising vibrations associated with one or more subjects moving on the floor;
isolate footstep vibrations from the sensor data;
communicate with at least one other sensor unit in the network of sensor units to obtain neighbor sensor data;
and
determine at least one of:
a number of subjects moving in the predefined area, a trajectory for at least one subject, or a location of the at least one subject based at least in part on the footstep vibrations and the neighbor sensor data.
