Wais, P., Wolin, A., and Alvarado, C. Designing a sketch recognition front-end: User perception of interface elements. In Proceedings of the 4th Eurographics Workshop on Sketch-based Interfaces and Modeling, SBIM ’07, ACM (New York, NY, USA, 2007), 99–106.

Summary:

This paper focusses on presenting a user study which investigates critical sketch recognition user Interface issues in systems that recognize hand-drawn diagrams. There are four critical sketch recognition user interface issues:

1) how users integrate the process of triggering recognition into their work.

2) when users prefer to indicate which portions of the diagram should be recognized.

3) how users prefer to receive recognition feedback.

4) and how users perceive recognition errors.

The paper believes that programs that can recognize students’ hand-drawn diagrams can revolutionize education. This is because they break down the barriers between diagram creation and simulation. This paper thus focusses on understanding how to support this new interaction paradigm from a user’s perspective.

Discussion:

The paper presents a very well conducted user study to understand the drawbacks and limitations of the exisiting systems. They have shown the data for Electrical circuits for the user study. It would have been really helpful to perform the user study in any other domain also.
