The scenario for communication and inter-
active/cooperative work between teacher and
students looks like this: (a) teacher and students
can see each other by using the standard video-
conference system based on two video cameras;
each camera needs to have a direct internet con-
nection and a real IP address; a broadband internet
connection is recommended; (b) the broadcast
quality is usually a standard TV broadcast quality
(for example a PAL video system has a 720 x 576
pixel resolution); (c) teacher watches students on a
computer monitor that is directly connected to his/
her videoconference camera; (d) teacher works on
his tablet PC which needs to have a direct internet
access; it needs to run a remote desktop control
server application (e.g. VNC); teacher runs the
course presentation or any support applications on
his/her tablet PC; (e) students watch teacher on a
projection screen; their videoconference camera is
connected to the multimedia projector; (f) students
are connected to the teacher's tablet PC by using
a remote desktop control client application like
VNC and are able to see teacher's desktop, i.e.
the presentation or any other application (students
need to have internet access); they may even
remotely work on teacher's computer (even an
on-line exam may be performed in this way); (g)
teacher controls who or if anyone can remotely
control his/her desktop; teacher may accept con-
nections in read-only mode when presenting his/
her course and then allows connections with
control rights for any interactive tasks. Figure 6
suggestively illustrates this scenario.
The architecture of the web-based course
revealed in this case study has a high degree of
versatility, meaning that with low effort and in a
very short time it can be adapted to many other
web-based courses in engineering. The system
described in this case study has been effectively
tested in practice, providing a very good satisfac-
tion both to students and teachers. After one year
of implementation, it was adopted by other ten
engineering courses (i.e. Computer Aided Design,
Creativity and Innovation in Engineering, Quality
Engineering and Management, Machine Elements
Design, Mechanisms Design, Hydraulic and
Pneumatic Systems, Objected Oriented Program-
ming, Integrative Project, Process Monitoring and
Control, Machine Tool Design).
