We present four empirical measures of the immediate usability of Graffiti, a character recognizer for pen-based computers. Since speed is fully controlled by the user, we measured the accuracy attainable after minimal exposure. The first measure, 79%, is the inherent accuracy, or the extent to which Graffiti strokes match letters in the Roman alphabet. The other three measures were obtained in ...

Tagging involves attaching descriptive keywords to data objects such as files and URLs. Most current implementations of tagging restrict the scope of tags to the website or application in which they w...

Contrary to this tradition, we show in this article that, when created by a human, there is inherent semantics in the positions of places, transitions and arcs. We propose to use the full definition of Petri nets: whe...
