Analysing Seating Using Pressure Sensors
First Claim
1. A computer-implemented method for analyzing automotive seating comprising a computer system automatically performing the steps of:
- displaying a seating image;
providing a user interface to allow the user to graphically locate anchor points on the displayed seating image;
receiving a location of the anchor points on a pressure sensor, the pressure sensor having an array of individual pressure sensing elements used to measure pressures on the seating;
accessing a pressure map of the pressures measured by the pressure sensor;
determining a mapping of locations on the pressure map to locations on the seating, based on the location of the anchor points on the pressure sensor and on the seating image; and
calculating performance metrics for the seating, based on the pressure map and the mapping of the pressure map to the seating.

Abstract
A pressure sensor measures the surface pressure distribution of a body supported by a surface, for example a person sitting on an automotive seating. In one approach, a pressure mapping system presents this pressure data in the form of a pressure map. The pressure map can be aligned to an image of the automotive seating including measurement zones of interest. The measurement zones of interest are mapped onto a human body model, which may include various body zones. In this way, the pressure distribution on different body zones can be visualized and interpreted to assess the performance of the automotive seating.
