Abstract
This paper considers current modelling techniques available to simulate the human and identifies future challenges in modelling the human interface with vehicles. Anthropometric, biomechanical and interface models are discussed. The capabilities and limitations of each are described and requirements for the future listed. The successful use of biodynamic modelling in the automotive industry is described. The advantages of mathematical models include overcoming the problem of varying body size and clothing and the presumption of static postures. The need for improved information on the workings of the human body is identified. Also required are representations of psychological processes.
