Abstract |
For Programming by Demonstration (PBD) systems to reach their full potential, a program representation is needed so users can view, edit, and share programs. We designed and implemented two equivalent representations languages for a PBD desktop similar to the Macintosh Finder. One language graphically depicts the program's effects. The other language describes the program's actions. A user study showed that both languages enabled users with no prior programming experience to generate and comprehend programs, and that the first language doubled users' abilities to generate programs. |

Notes |
Francesmary's Pursuit system comes close to CNA's functionality in its effort to represent an evolving program while the user is demonstrating. However, the evaluation does not try and assess what is learned from showing the evolving program versus not showing it. Instead, she assesses the appropriateness of two competing program representations. |
