Abstract:

A digital lens is a user interface mechanism that is a potential solution to info1mation management problems. We investigated the use of digital lensing applied to imagery analysis. Pa1ticipantscompleted three different types of tasks locate, follow, and compare using a magnification lens with three different degrees of offset aligned, adjacent, and docked over a high-resolution aerial photo. Although no lens offset mode was significantly better than another, most participants preferred the adjacent mode for the locate and compare tasks, and the docked mode for the follow tasks. This paper describes the results of a user study of magnification lenses and provides new insights into preferences of and interactions with digital lensing.
