The software can guide users to careers that may be of interest to them based on their interactions with the software and their exploration patterns.

We designed educational software to teach middle-school and high-school girls computer programming by having them make a character perform dance moves. Learning to program will be an incremental process where new users can play with pre-programmed dances and see how they are broken down into dance moves. More advanced users can create their own dances by programming body movements and building dance moves.

The Learning Channel's popular show Junkyard Wars pits two teams against each other to build a very technical device using materials found in a junkyard within a 10 hour time limit. Given these constraints, we were interested if there is a common design process used by the teams. Additionally, we were interested if certain elements of the process correspond to creating a successful or unsuccessful design.

The campus poses a special challenge to the new student since many of its buildings are most quickly accessed via unnamed paths and alleys. The system can also help students find the location and information about departments, people and events on campus.
