Graphical annotation based interactive techniques in eTrace eLearning environment

Year: 2008
Type of Publication: In Proceedings
Keywords: eLearning, annotation, collaborative work, 3D annotations
Authors: Ştefănuţ, Teodor; Gorgan, Dorian
This paper presents the experiments taken over the interaction techniques based on 2D and 3D graphical annotation in an eLearning environment, named eTrace. 2D annotation is independent from the type and format of the 2D documents or 3D objects that are annotated. The user has the ability to make 3D annotations by drawing directly on the surface of the 3D objects. The annotation techniques are tested end exemplified in the context of lessons from different domains like mechanics, physics and aeronautics.
