This demonstration shows the tool we have developed for hand-sketching user interfaces. Our motivation for developing this tool is to provide an environment where novice programmers can move freely along the design continuum from informal low-fidelity prototypes to completed formal designs. A low-cost digital whiteboard is used to provide a shared work space for Freeform. The tool is integrated into a programming IDE and provides penbased sketching and editing, a storyboard, run mode, recognition of shapes and words and conversion into a formal design in the programming IDE.
