Superimposition of 2D pressure data and 3D surface data to optimize seat shells in rehabilitation

Abstract

The individual adaptation of seat shells is a very difficult task, especially in the case of disabled patients who are unable to articulate their requirements [1]. Besides the individual body geometry the amount of pressure has to be considered particularly with regard to the patients who use the seat shells all day. Congestion has to be reduced to prevent decubitus [2]. Typically the pressure load is measured by a sensor mats that deliver a 2-dimensional result [3]. To optimize a seat shell under geometrical and pressure aspects the 2-dimensional data of the pressure measurement have to be superimposed with the 3-dimensional surface data of the seat shell. © 2009 Springer-Verlag.
