The objective is to simulate and predict the performance of Army personnel riding in a ground vehicle subject to vibrations. Established software tools are available for parts of this problem: anthropometrics for reach and vision analysis, vehicle dynamics for vibration and ride quality analysis, and biodynamics for human motion in response to force inputs. In Phase I we propose to write a software specification to integrate selected software components that will efficiently and accurately set up and analyze this class of problems. The team members own the source code that will be integrated (JACK, VDANL and BIODYNE). The innovation is to use manual control as a means to define and measure task performance. Representative closed loop tasks such as driver avoidance maneuvers or target tracking will be defined, and the vehicle will be considered "good" if these tasks can be adequately performed, by different sized drivers and passengers, traveling over different types of roads and terrains. A sample problem will be selected and analyzed in Phase I using the non-integrated software tools and a rapid prototype visual interface will be developed. The Phase II objective is to develop and validate a prototype of the integrated software package.An integrated tool for predicting human task performance on moving platforms does not currently exist and has many potential military and commercial applications. These include ambulances, fire engines, off-road vehicles, agricultural equipment, rotorcraft and aircraft. The use of manual control provides a natural way to define and more importantly validate task performance. Existing customers of the software components (such as TACOM) will have increased capabilities.
