Abstract

This paper presents the experiments on the user interaction techniques based on the 2D and 3D graphics annotation, developed in eTrace eLearning Environment. The 2D annotation technique does not depend on the type of the 2D documents and 3D objects. The user has the ability to make 3D annotations by drawing directly on the surface of the 3D objects. eTrace has been developed and experimented the annotation techniques in the context of lessons from different domains such as mechanics, physics, and aeronautics.
