Our objective is to revolutionize Human Systems Integration (HSI) analysis through the integration of full-body motion capture (mocap) technology. Mocap enables the rapid and accurate digital simulation of human-centered tasks, significantly reducing the reliance on time-intensive and costly physical mock-ups. By identifying potential design, manufacturing, and maintenance issues early in the development process, organizations can address challenges more efficiently and cost-effectively. This approach also contributes to improved safety, cost, operational efficiency, overall system performance, and program schedule.
