Abstract
Apparatus for detection and identification of footfall, comprises an arrangement of pressure detectors on a horizontal surface; a footfall pattern detector to receive a sequence of signals from each pressure detector in distinguishable manner over a time frame, to build from said signals a time evolution of a footfall event on said horizontal surface; and a tracker to compare different time evolutions, and thereby to connect together different footfall events to track a person or object over said horizontal surface.

Apparatus for detection and identification of footfall, comprising:
- an arrangement of pressure detectors on a horizontal surface;
- a footfall pattern detector connected to receive a sequence of signals from each pressure detector in distinguishable manner over a time frame, the detector being configured to build from said signals a time evolution of a footfall event on said horizontal surface;
- a time evolution tracker unit configured with registers to compare different time evolutions, and thereby to connect together different footfall events to track a person or object moving over said horizontal surface, wherein said time evolution tracker unit is configured to use said registers respectively to track a first evolution of a volume center of mass and a second evolution of a shape center of mass;
- and
- a comparator configured to extract a parameter relating said volume center of mass and said shape center of mass.
Method for detection and identification of footfall, comprising:
- providing an arrangement of pressure detectors on a horizontal surface;
- receiving a sequence of signals from each pressure detector in distinguishable manner over a time frame;
- building from said signals a time evolution of a footfall event on said horizontal surface;
- comparing different time evolutions, wherein each said time evolution comprises a first evolution of a volume center of mass of said footfall event and a second evolution of a shape center of mass of said footfall event;
- extracting a parameter relating said volume center of mass and said shape center of mass of said respective footfall event;
- and
- connecting together different footfall events to track a person or object moving over said horizontal surface.
