Different interfaces allow different scenarios of interaction. However, a common
use scenario for all of the described technologies is e.g. a
slate perspective
.Inthis
scenario the augmented reality display is a “window” to view data overlaid on a
real-time image of a subject.
Haptic Interaction
As noted in Sect.
5.4.2
, touch and haptic interfaces play significant roles in medical
applications. An example of a haptic environment is presented in Fig.
5.10
.The
ability to give haptic feedback, while preparing pre-operational planning, is crucial
for achieving success in medical procedures e.g. assembling fragments of fractured
bones. Vlasov et al. describe different approaches for haptic rendering [

]. As
many diagnostic procedures involve touch examination, creating a synergy between
touch and access to digitally recreated multiscale content can be invaluable as a new
diagnostic modality.
Gesture Interaction
As it has already been mentioned, much of multiscale medical content has rich diag-
nostic meaning and can be used for pre-operational planning. Therefore, creating a
strategy for utilizing gesture interaction for a sterile surgery room should be consid-
ered as important.
This kind of interaction should not only be limited to navigation but could also
allow interactive modification and processing of data. Beside hand gestures, facial
expressions can play an important role in multiscale environments. As an example,
visual systems detecting an eye wink can help in reducing user tasks [
