I'm happy to announce the release of CALI version 1.1. CALI is a software library for the development of Calligraphic Interfaces (intelligent interfaces based on sketch and gesture interaction) centered mainly on a simple Shape Recognizer. This recognizer is a fast simple and compact approach to recognize Scribbles (multi-stroke geometric shapes) drawn with a stylus on a digitizing tablet. Our method combines temporal adjacency, Fuzzy Logic and geometric features to classify scribbles. It recognizes elementary geometric shapes, such as Triangles, Rectangles, Diamonds, Circles, Ellipses, Lines and Arrows, and six gesture commands, Delete, Cross, WavyLine, Move, Copy and Tap. Shapes are recognized independently of changes in rotation, size or number of individual strokes. The recognizer has a recognition rate of 97% and fast response characteristic making it very usable in interactive applications. The library is written in standard C++. Currently it compiles under GNU g++ (Linux) and Visual C++ (Windows). The source code and documentation is released under the terms of the GNU General Public License.
