This project involved re-imagining an extensive desktop application called Command Post of the Future (CPOF), as a smaller-scale Android tablet application for a subset of users.

CPOF is such a large and complex application that the desktop version is often used with three monitors at once. While that size of a display is not a match for mobile use, there are features that users who travel between bases (such as higher-ranking individuals and their assistants ) would love to have. They want to keep up to date on developing situations and make updates as they gather information. Our tablet includes a targeted subset of functionality such as a live map and graphic annotation that supports these needs.


Working within a small team, we moved from upfront research to a working prototype over the course of a few months. We explored and tested different interaction patterns and were able to bring in entirely new features and interactions, taking advantage of the tablet's camera, GPS, and touch input.

Over the course of the project, there were primarily two designers, including myself. We interviewed subject matter experts and did several rounds of think-aloud usability testing with them, both with paper prototypes and with our live prototype. We also tested with co-workers unfamiliar with the project details and got feedback very efficiently.

At the end of the project, it was presented to clients in the U.S. Army and was enthusiastically received.
