Before revision: Sensing floors typically employ load sensors or proximity sensors (to detect, track, and recognize humans), but can also contain magnetometers (to detect metallic objects like robots ).Depending on the type of sensors employed, floors can be load-sensing,
After revision: Depending on the type of sensors employed, sensing floors can be measure load (pressure), proximity (to detect, track, and recognize humans), as well as the magnetic field (for detecting metallic objects like robots using magnetometers).
