Four decades of SAMMIE

SAMMIE (System for Aiding Man Machine Interaction Evaluation) is a digital human modelling system that has been in development and use for the past 40 years. Three-dimensional geometric representations of working environments and specific equipment can be built using SAMMIE and evaluated using a human model that is a 3D representation of the human body with articulation at all major body joints. Joint movements are constrained in a realistic fashion and the body shape can be varied to represent the size and shape of the relevant national or occupational populations. SAMMIE is intended for use in the very early stages of the design process, potentially saving costly design changes, to test the suitability of environments for the appropriate user populations.
