Adapting LifeLines to Army Officer Personnel Processes

Visualizing personal histories requires a tool that can present users with multiple time intervals along with supporting information. The Human-Computer Interaction Lab (HCIL) at the University of Maryland created LifeLines, a visualization tool for personal histories in 1994 to visualize youth records [7]. The software was recoded in 2003 to facilitate easy zooming, but not all of the original functionality was incorporated. Our work implements some of the original functionality in the new coding structure, corrects errors which became apparent with a new data set, and adapts LifeLines for use by the United States Army in officer assignments, promotions, and selections. At this time, the Army is reviewing the software for integration into their personnel processes.
