Accessing insights from underrepresented populations, such as adolescents, remains a persistent challenge in the research and design process. The paper will investigate the utility of online videos of user-posted materials as an innovative research tool. Unlike traditional in situ approaches to studying human behavior and public space, online videos permit access to multiple sites based upon the population or activity of interest. The approach is similar to studies of behavior using unobtrusive observation—where participation or interviews might interrupt the activity under observation or where access to the setting of the activity would otherwise remain inaccessible to the researcher.
