Quantitative responses for hyperlinks (all statements are transformed to their positive
form. Error lines indicate the 95 % confidence intervals of the means. ** = statistically significant)
the fact that Li et al. used tap-and-hold for mode switching in a drawing application,
where mode switching occurs very frequently. In contrast, creating links is an activ-
ity that is performed only at an infrequent basis. In this latter case, holding down the
pen for half a second is much more acceptable. As indicated by several participants,
this short interruption is even supportive because it underscores that a special mode
for creating (instead of following) a hyperlink is now being entered.
The separate hyperlink column was appreciated for enabling a quick overview of
all links. However, four participants desired the possibility to also create hyperlinks
on individual words directly within the document.
As far as following links is concerned, this was also rated to be significantly
quicker and faster than in the control condition (see Fig. 6.12). The difference is
particularly pronounced for cross-media hyperlinks between a printed document
and a Web page, but also for hyperlinks between two paper pages, the difference
is considerable. Following cross-media hyperlinks was judged to be very easy with
CoScribe
8
whereas the value is significantly lower in the control setting
9
. Following
hyperlinks between two paper documents was judged to be slightly less easy
10
,
but still much easier than without CoScribe
11
. Again, this difference is statistically
highly significant.

A cross-media hyperlink can be followed significantly more
quickly
13
than a traditional reference
14
. The difference is slightly less pronounced,
but still significant, for links between two paper documents with CoScribe
15
vs. in
the control setting.
