eLearning Applications based on 3D Graphics Annotation Techniques
Journal Title: Romanian Journal of Human - Computer Interaction - Year 2008, Vol 1, Issue 1
Abstract
The graphics annotation in user interfaces, instead of classical radio buttons, check boxes and other controls, supports new interaction techniques that provide the user possibilities for free form presentation, highlighting user’s creativity, practical ability, and artistic imagination. The graphics annotation performed directly on the 3D object’s surface requires the development of new drawing algorithms, annotation models, and interaction techniques. The research experiments in eTrace eLearning Environment the model and techniques for graphics annotation supporting the automatic evaluation in the context of eLearning lessons. The paper describes shortly solutions for the steps through which the teacher describes the annotation related constraints, recording the annotation specifications in the lesson’s model, achievement of student’s annotation, knowledge quantification, and final mark computation. This paper details mainly the first step of the constraint description. The paper proposes new research directions concerning with knowledge evaluation approaches instead of the common multiple choice questions.
