Graphical user interface of a hypervideo system (see also Zahn & Finke, 2003). A
dynamic sensitive region, “hotspot” within the video (white frame on the
left
) is connected via
multiple links to other materials (e.g., a text document, on the
right
)
Hypervideo is thus denoted as a “dynamic information space” of a collaborating
group (
DIS
, Zahn & Finke, 2003; Chambel, Zahn, & Finke, 2005).The system was
first developed for unspecified learning or work situations. The basic idea was that
structuring hypervideos by dynamic links can serve to promote both learning to inte-
grate different information elements and developing nonlinear knowledge structures
by collaboratively designing information and discussion links. Users of this hyper-
video system can create their own dynamic sensitive regions (“hotspots”) within
video materials and add multiple links to these sensitive regions. Links can con-
sist of data files uploaded from a local computer, as well as URLs. The links (or
associated information elements, respectively) can then be discussed by means of
an integrated e-communication tool. Thus, both randomly accessing videos and
adding one's own new information and knowledge becomes possible. The web-
based graphical user interface (see Fig. 25.2) allows the adaptation due to different
GUI layouts and consists basically of a video player that visually displays the spatio-
temporal hyperlinks within the video frame and offers functionalities in order to
create new video annotations. Newly created video annotations are immediately
transferred from the client to the server in order to be instantly shareable by the com-
munity. An example of a similar digital tool is the web-based application Asterpix
(
