2 Ph.D. students (Computer Science), 2 graduate
students (Computer Science), 3 graduate students
(Mathematics), 5 undergraduate students (Biol-
ogy), 4 undergrad students (MIS), 2 Medical
Doctors (Health Center), 2 patients with some
technical knowledge and 3 patients without techni-
cal knowledge were chosen as the users. We have
tried to cover all type of end users and both males
and females having different ages. 2. What tasks
will be analyzed? The services provided by our
MAS were executed by the users. We have tried to
select the tasks to be analyzed in such a way that
no major task has been overlooked. 3. What is the
correct action sequence for each task? First, we
briefly explained the task sequences and process
to get result. A questionnaire was given to the
users. Table 1 shows the user's satisfaction rating
[0 is the lowest value and 5 is the highest value].
This study makes a contribution in the field
of mobile health care delivery. Researcher wish-
ing to provide a patient monitoring technology
that is based on SMS to complement existing e-
Health systems will have something to gain also
from the article. The analysis from the findings
shows Overall (3.6), Ease of Use (3.9), Ease of
Input (4.3), Interface Navigation (4.5) and User
Satisfaction (4.0. The resultant average rating of
(3.6+ 3.9+ 4.5 + 4.3+ 4.3/5 is 4.06 Several us-
ability studies suggest that system with “Very Bad
Usability” should have 1 as mean rating, “2 as
Bad Usability”, 3 as Average Usability, “4 as Good
Usability” and “5 as Excellent Usability”. It was
proposed (Sauro, 2005) that “Good Usability”
should have a mean rating of 4 on a 1-5 scale and
5.6 on a 1-7 scale. We can therefore conclude that
the prototype MAS application presented in this
chapter has “Good Usability” based on the aver-
age total rating of 4.06
CONCLUSION
In this work, we have illustrated how to enhance
health care delivery on a global scale by develop-
ing and evaluating a medical alert system (MAS)
which sends medical to patients via handheld
