The trick is that the system measures the pressure people apply on the seat through a set of 360 sensors.
Each sensor is measuring pressure by its own and sends the information to a laptop, which aggregates the information to show key data like the highest value of pressure, area of contact on the seat (see below), and other factors. According to its makers, the system was able to identify drivers with 98% accuracy during experiments.
