vation to conclude how far the training in the virtual
environment could increase their motivation. To il-
lustrate the influence of the training with CordiAAL
we have taken two aspects into account. The moti-
vation for doing sports with and without any general
technical aids, and the same with CordiAAL as a spe-
cific technical aid. Figure 16 clearly illustrates that
the subjects have difficulty doing sustainable sporting
activities and also the willingness of using aids is low.
In turn, the increasing motivation through the virtual
training is clearly evident. An increased value for the
readiness to use CordiAAL as a technical aid for reg-
ular sport activities was also indicated. The most im-
portant motivation factor was thereby the training in a
virtual group. It was stated that the training and com-
munication with other group members minimize the
effort of training and increase the ambition.

willingness to use the aids, divided according to data ob-
tained from the self-assessment and evaluation after training
with CordiAAL.
7 CONCLUSIONS
The user study clearly demonstrates that the main ob-
jectives of the CordiAAL system were achieved, real-
izing a playfully ergometer training which motivates
users to a regular physical activity, bringing users
with different fitness levels together and to give them
safety at the same time.
This is done by a permanent monitoring of vital
data and an adjustment of the ergometer load based
on these data. Since the study was not conducted
with subjects with heart disease, for ethical reasons,
the question of the decrease of anxiety remains open.
The next stage in the evaluation would be a long-
term study to check if the motivation stays high-
leveled in a long-term use.
