Remembering WW1 app for US National Archives. The National Archives and Records Administration (NARA) documents materials created in the course of business conducted by the United States Federal government. They wanted to increase public engagement and reuse of their newly-digitized collection of World War I moving and still images. We worked with NARA to help them work across internal units, identify communities that could benefit the most through reuse of NARA content, understand the needs of these communities, and focus content for greatest impact. We assisted the agency in carrying out a user-centered design process to analyze target audiences, identify new ways of searching and accessing the content, and reaching new communities of users. We designed and created a tablet application for use in classrooms & communities to explore the history of WWI through crowd-sourced data and freely available content.
