Goal of this thesis was development of interactive graphic
editor for graphic representation, examinationh and annotating of records of electrohysterogram (electromyogram of uterus). We developed a graphic user interface LANNOT, which displays signals of records, allows manual and semi-automatic setting, deleting and examining of annotations, full editing of accompanied clinical information, generation of scripts and generation of new procedures. The types of the annotations should regard true contractions, other electrical activities of uterus, baby movements, and noise of signals. The interface was developed using Netbeans IDE tool to develop interactive graphic user interfaces. The developed editor is based on object-action paradigm. During designing of the editor, we followed Nielsen's principles of interface design and commonly accepted guidelines of user interface design, while the most important usability dimension was efficiency. The developed editor will be used by expert obstetricians during their clinical praxis. It will also be used for annotating of international, freely available, reference TPEHG DB (Term Pre-term ElectroHysteroGram DataBase) database. The annotations set by expert obstetricians regarding contractions of uterus and other electrical activities of uterus, will allow different kinds of automatic analysis of records and evaluation of their performance.
