Usability study on the use of handheld devices to collect census data

Usability staff at the U.S. Census Bureau developed and ran two iterative usability sessions on the mobile computing device (MCD) being evaluated for possible use in collecting interview-administered short form data in the 2010 Census. Previously, the Census Bureau has used paper forms to collect this information. Our objectives were to assess several measures of performance and satisfaction (e.g., accuracy, efficiency, ease of use). We observed 14 test enumerators as they conducted four different interviews, two per session. Except for minimal training, enumerators were unfamiliar with MCDs and conducting interviews. Results indicate that although the site did meet some objectives (accuracy and satisfaction), the screen layout could be improved in several areas for a better overall user experience. In addition, efficiency did not meet performance objectives and needs improvement. The device holds promise for development and implementation in 2010.
