"Sketch-n-Sketch: Interactive SVG Programming with Direct Manipulation" by Ravi Chugh

Programmatic and direct manipulation systems have distinct and complementary strengths, but users must typically choose one over the other or use some ad-hoc combination of systems. As an attempt to bridge this divide, we are developing an interactive programming system called Sketch-n-Sketch for creating Scalable Vector Graphics. Sketch-n-Sketch offers a high-level, functional programming language paired with GUI-based tools for manipulating program output: these tools help to encode user intent by semi-automatically rewriting the program with new relationships, and help to preserve existing relationships in the program when output values are directly manipulated. The resulting workflow allows for prototyping a design much like in typical GUI-based tools and then iteratively adding more structure to the program with guidance from the system. In this talk, we will demo Sketch-n-Sketch, describe our approaches to the technical challenges, and discuss ideas for combining programmatic and direct manipulation in other settings.
