A paperless environment for annotating student assignments is appealing to teachers and students. However, to do this, while retaining the richness and ease of annotating the work with a red pen, has not been possible until recently. This project presents an annotation problem that requires digital annotation, and additionally functionality to properly(More)
Prior empirical work on layout aesthetics for graph drawing algorithms has concentrated on the interpretation of existing graph drawings. We report on experiments which focus on the creation and layout of graph drawings: participants were asked to draw graphs based on adjacency lists, and to lay them out "nicely." Two interaction methods were used for(More)
We present McSig, a multimodal system for teaching blind children cursive handwriting so that they can create a personal signature. For blind people handwriting is very difficult to learn as it is a near-zero feedback activity that is needed only occasionally, yet in important situations; for example, to make an attractive and repeatable signature for legal(More)
Touch and stylus sensitive computer displays are widely available. Yet, the development of gesture sets to support these interaction methods continues to be difficult. We present RATA, a tool for interaction designers and software developers to create gesture recognizers for novel and custom gesture sets. Guided by the RATA wizard, the developer: defines(More)
Digital hand-drawn sketches provide a new and unique way of interacting with a prototype user interface design while it is still rendered as a sketch. The successful use of prototypes and scenarios for exploring design ideas is well documented. Hand-sketched designs have also been found preferable to formal diagrams during early design. The study reported(More)
