SAMMIE: an ergonomics CAD system for vehicle design and evaluation

SAMMIE (System for Aiding Man-Machine Interaction Evaluation) is a CAD system which enables the ergonomics/human factors evaluation of vehicle designs to commence at the earliest stages of the design process. Evaluations of postural comfort and the occupants' clearances, reach and vision should be undertaken from the concept stage when design modifications are easier and cheaper to implement than at the pre-production stage. In order to achieve this, the package offers 3D modelling of vehicles and their occupants. Details of the package and its application to vehicle design are presented.
