Workstation and Equipment Layout Tools (continued)

  • Physical Mock-ups - CAD drawings are very useful in determining physical layout and configuration.  Nonetheless, it is often appropriate to build full-scale mock-ups for user evaluation for anthropometric "fit" and ease-of-use and to identify and resolve any remaining physical interface design problems.

  • Virtual Reality - Some Computer Aided Design and Modeling software performs virtual reality modeling, enabling the user to "walk" or "traverse" through an environment.  Although displayed on a 2D monitor, screens are created with visual cues that create the illusion of 3D.  Advanced virtual reality systems use equipment such as head mounted displays and special gloves to enable users to enter, explore, and interact with a simulated environment.
