The CoScribe document viewer
the symbols of annotations that are not considered relevant can be removed from the
view.
This has the advantage that the entire document remains readable and is dis-
played at a reasonable size. However, not all annotations are visible at the same
time. For quickly gaining an overview of all annotations, CoScribe includes a pre-
view function, which displays all shared annotations in small size. Moreover, a view
of all annotations made by a particular user is displayed when pressing a specific key
while hovering over or tapping on an annotation of that user. This way, a single-user
view displaying only the annotations of one specific user can be easily accessed.
The multi-user and single-user views complement each other. While the multi-
user view serves well for getting an overview of all annotations on a page, the
single-user view is better suited when specifically focusing on the annotations of
one specific user, for instance those of the instructor or those made by a student
known for making helpful annotations.
CoScribe offers representations for printed documents that are equivalent to the
digital single-user and multi-user views. Users can print documents including the
annotations of one single user. This corresponds to the single-user view. In con-
trast, printing the annotations of multiple users poses the same challenges as on
the screen because annotations of different users might overlap. However, in con-
trast to screens, dynamic scaling of annotations is not possible. For this reason, the
print module generates a layout in which the document page is slightly scaled down.
