Abstract
A system, method and computer program product for hand-drawing diagrams including text and non-text elements on a computing device are provided. The computing device has a processor and a non-transitory computer readable medium for detecting and recognizing hand-drawing diagram element input under control of the processor. Display of a plurality of input diagram elements in interactive ink is performed on a display device associated with the computing device. At least one diagram element is identified as a connector which connects a plurality of diagram elements. Geometrical characteristics of the at least identified connector are determined and the diagram elements are re-displayed based on one or more interactions received with the interactive ink of the at least identified connector or one or more of the plurality of diagram elements connected thereby and in accordance with the determined geometrical characteristics.
