Abstract: We address the problem of how pen-based interfaces for mathematical software systems can be organized. We describe our approach to such interfaces for mathematical packages and document processing software. Our architecture includes components for ink collection, mathematically-oriented recognizers, portability support and interfaces to applications. We summarize aspects of mathematical handwriting recognition and discuss the methods we have used for individual character recognition and overall expression analysis. We present our pen-based computing environment Mathink and give an overview of facilities for training, ink annotation, and testing.
