Team process is a key point in the study of military isolated and confined environments and the primary problem is the measurement of team performance and personal contextual performance. It is difficult to carry out the traditional measuring methods in military isolated and confined environments, which are time-consuming, labor-consuming, inaccurate and subjective. The application of unobtrusive measuring methods, especially the application of sociometric badges, can solve the above problems. At present, sociometric badges already can predict personality, team performance and team process-related characteristics. Although sociometric badges have the disadvantages of low discrimination validity, low content validity, and difficulty in measuring individual contribution to the team, their portability, non-invasiveness, feedback and automaticity almost guarantee their future in military isolated and confined environments.
