User Interaction Techniques based on 3D Graphical Annotation in eLearning Environments
Journal Title: Romanian Journal of Human - Computer Interaction - Year 2014, Vol 7, Issue 4
Abstract
Multimedia eLearning resources (i.e. images, video files, and 3D models) allow the exemplification and intuitive representation of high complexity concepts. At the same time, the interaction with these resources cannot be efficiently implemented nu based on text communication and analysis (i.e. chat, email, forums). In order to enable the users involved in didactic activities, either trainers or trainees, to focus on the content of the materials and less on learning the interaction tools and methods, we propose the use of graphical annotations as the base of a new user interaction style. Specific interaction techniques will be described throughout the article, for each phase of the teaching process: resources creation, resources analysis, communication between participants in the context of the information presented, knowledge evaluation. In order to enable natural integration of 3D graphical annotations in the lesson model we will also describe a new modelling approach, both at the control level (e.g. creating new resources or modifying the visual structure of existing ones) and analysis/representational level (e.g. represent student answers to specific problems).
