The purpose of this work was to develop a database of human model behavior primitives, which are basic scripts that can be chained together to create simulations of humans performing certain tasks. This is unique in that the human model behaviors were collected using motion capture technology and then incorporated into virtual simulation software. Typically, human model behaviors are created based on the subjective observations of the analyst rather than by using realistic motion data. Limitations of this approach include less reliable human models and a more time-consuming process for creating the human model in the virtual environment.

Based on a prioritized task list, a lab study was designed to capture scripted motion sequences performed by participants in a fully operational motion capture and human modeling lab. Motion capture data was stored in a database of postures and motions. Human factors analysts may use the database to create digital human models for use in virtual assessments of launch vehicle ground processing and maintenance tasks.
