New system uses floor vibrations to track people in a building

Researchers have developed a tracking system that can determine the number of people and their movement in a building by analyzing floor vibration from steps.

Today, many public and industrial premises are equipped with surveillance systems. They usually use people’s cameras or mobile phones to track people. Such technologies violate privacy and can be ineffective in fires and other emergencies. Therefore, scientists from the Federal Polytechnic School of Lausanne have developed an alternative.

The new system analyzes data from sensors located in building floor slabs, separating the vibrations of human footsteps from other background noises. Advanced algorithms can also identify the walking styles of the same person in different circumstances.

Unlike other existing solutions, the new system requires only one sensor for every 15–75 m2 for effective monitoring, and does not require the same hardness values ​​for the floor slabs.

According to the developers, the technology can be used to optimize energy management models in offices, improve the security of banks, data centers and other similar buildings, as well as determine the location of people in emergencies or hospital patients.

Recall that recently, scientists have developed airbrushing ink that turns any surface into an electronic control panel.
