Training

Human-System Interaction (HSI) is the study of interfaces between humans and technical systems. The Department of Defense incorporates HSI evaluations into defense acquisition to improve system performance and reduce lifecycle costs. During operational test and evaluation, HSI evaluations characterize how a system’s operational performance is affected by its users. The goal of this course is to provide the theoretical background and practical tools necessary to plan and evaluate HSI test plans, collect and analyze HSI data, and report on HSI results....

Effective training of the broad set of users/operators of systems has downstream impacts on usability, workload, and ultimate system performance that are related to mission success. In order to measure training effectiveness, we designed a survey called the Operational Assessment of Training Scale (OATS) in partnership with the Army Test and Evaluation Center (ATEC). Two subscales were designed to assess the degrees to which training covered relevant content for real operations (Relevance subscale) and enabled self-rated ability to interact with systems effectively after training (Efficacy subscale)....
