This master thesis investigates if any
applicable methods for evaluating mobile
systems exist, and how feedback to the
designers of the system can be provided.
This is done by conducting a literature
review of past research within the area
of Human-Computer Interaction with focus
on user-based usability evaluations. The
study provides an overview of tendencies
in this area, and the results from the
study are utilized in the design and con-
duction of two usability evaluations; one
in a laboratory and the other one in field
settings. The purpose of these evaluations
is to investigate how, and in which set-
tings, evaluations of a mobile system can
be conducted. Two usability reports, docu-
menting the usability problems identified
in the respective evaluations, are used as
a foundation for providing feedback to the
designers of the mobile system. The result
of the thesis is a presentation of an ap-
plied method for evaluating mobile systems,
and insight into how usability reports can
be used as a mean for providing feedback
to designers.
