Presentation, in a form of a sketched graphical diagram, is often used as a training approach of various didactic levels. However, the trainee examination using the hand-sketch diagrams is still not a common practice, due to the evaluation complexity; both for a teacher and for an automatic recognition system. The elaborated interface, supported by the low-level recognition algorithm, simplifies the evaluation procedures. The solution removes both interpretation uncertainty factor and simple errors from the sketch, using the user interaction interface. The users interaction is based on online pattern recognition of strokes in a colour context. Their representation is returned to the user and stored as a graph structure. Additionally, the interface tracks the sketch creation process for more precise final evaluation. The interface can support many fields as various as business, computer science, mathematics, engineering, music and so on; where a set of graphical symbols are lines and curves composition.
