Abstract :
In this paper, a gesture-based editing system is proposed for the recognition of on-line handwritten chemical expressions. We put forward a set of operations, including eleven independent gestures, which are easy to recognize and quick to learn. In gesture recognition section, we propose a two-tier classification, which deals with the global as well as the local features of gestures. The results show that these gestures are well-designed and easy to recognize. We have applied these gestures to the chemical formula editing system.
