A LIGHT-WEIGHT SEMANTIC INTERPRETATION MECHANISM FOR A SKETCH-BASED LEARNING ENVIRONMENT

Abstract

Free-hand drawing of diagrams or sketches is a natural form of expression that is very useful in learning scenarios. It is easily supported by tablets or tablet PCs. Often such sketches are the basis of reasoning processes, also in collaborative scenarios. They can also indicate misconceptions. Therefore it is desirable to support a semantic interpretation of sketches in a way that could be easily combined with other parts of a learning environment or with an ITS. Our solution introduces a multi-agent architecture based on the blackboard paradigm. Inspired by the CogSketch system, it supports the introduction of user-defined "glyphs" as external representations of concepts, it provides a set of basic geometrical/topological primitives and allows for the addition of more domain-specific semantic relations.
