Advanced human-computer interaction in external resource annotation

Abstract

This paper presents innovative multimedia annotation methods based on advanced human-computer interaction and (a)synchronous interpersonal collaboration features. They have been implemented within ERA (External Resource Annotation) framework with the scope of going beyond the existing solutions by introducing new annotation types using external resources. Thus, anyone can easily annotate the own resources with additional information such as real-time handwriting, text and animation, or even audio/video sequences stored into public data repositories, or recorded ad-hoc, in order to create value-added interactive content. ERA framework also provides an advanced rendering tool for such complex multimedia resources.
