This paper presents the development and testing of a tool for designing vehicle operator workstations using 3D anthropometry. The tool consists of two major modules: 1) a webbased engine to query a large database of human anthropometry for selecting human operators representative of a specified user population, and 2) an immersive Virtual Reality (VR) software application used to view the selected anthropometry in relation to vehicle CAD designs. This tool allows a designer to view and interact with fully immersive 3D representations of vehicle operator enclosures and controls from typical CAD models along with digital human models selected from the anthropometry database. This environment allows visualization to aid in the trade-off decisions that come between ergonomic and functional (i.e. structural, electrical, etc.) design. The environment makes use of a webbased interface for the querying of a large anthropometric dataset with over 4500 participants. A designer is presented with a rich set of features to build, store, and manage queries using attributes such as height, weight, reach, gender, and occupation to locate pertinent subsets of subjects for a specific vehicle design. A list of subjects obtained from the query engine can then be sent to a VR environment for viewing with vehicle CAD data. This linkage makes the selecting and viewing of subjects seamless. A detailed description of the design problem being addressed, software development, and sample test cases are presented to demonstrate the intuitive nature and ease of use of the environment.
