EVA contains two parts: a video streaming part and a part for displaying seg-
ments of video temporal bookmarks, called cue-segments, and their associated lists
of users' annotations. Figure 12.5 illustrates the main user interface for EVA system
showing both the video streaming on the left side and the list of annotations for a
cue-point on the right side. At any time in a video, a user can create a comment that
is pertinent to the context of the video at that particular time-point. EVA will gen-
erate a new cue-point and prompt for a cue-point description whenever a user tries
to bookmark a new time-point. Otherwise, a user can append a new annotation to
the list of annotations at a particular cue-point. The collection of cue-points forms
a list of indices for user to navigate within the video content. Each annotation can
be entered and modified by the owner of the annotation via a friendly WYSIWYG
HTML editor and can contain images, diagrams, and other HTML hyperlinks. Each
annotation can also be deleted and edited by the author. Because multiple users can
annotate at each time-point of the video, each annotation is identified by the user,
the time of creation, and the time of last modification.
Several pilot projects in teaching and learning using the EVA platform are
currently being conducted at the University of Sydney in sport coaching, child
development psychology, teacher professional learning, and social works. In sport
coaching, each student coach videotaped both a live session of his/her coaching a
team in an actual sport engagement and a live session of his/her private coaching
of individual team member. Both videos were then uploaded onto the EVA plat-
form for the teacher and peer student coaches for comments. The aim of the pilot
