Programming-by-demonstration (PBD) can be used to create tools and methods that eliminate the need to learn difficult computer languages. Gamut is a PBD tool that nonprogrammers can use to create a broader range of interactive software, including games, simulations, and educational software, than they can with other PBD tools. To do this, Gamut provides advanced interaction techniques that make it easier for a developer to express all aspects of an application. These techniques include a simplified way to demonstrate new examples, called "nudges," and a way to highlight objects to show they are important. Also, Gamut includes new objects and metaphors like the deck-of-cards metaphor for demonstrating collections of objects and randomness, guide objects for demonstrating relationships that the system would find too difficult to guess, and temporal ghosts which simplify showing relationships with the recent past. These techniques were tested in a formal setting with nonprogrammers to evaluate their effectiveness.
Gamut REF is a PBD system that enables non-programmers to create interactive games and educational software using demonstrations.
