In addition to software quality and tariff structure,
user experience has a decisive influence on the
market success of mobile applications. Thus, it is
necessary to get valid feedback from future users
during the software development process. However,
studying the generation of feedback regarding usability
and user experience is still at the beginning
and is currently an immature discipline in computer
science.
Therefore, we present a concept for the generation
of feedback in the software life cycle of mobile
applications.
A fundamental approach is the implicit
and explicit collection of user feedback. This is
achieved by an automated recording of user activities
(e.g. key-events) in the appropriate context of
use, as well as an in situ collection of explicit feedback
through questionnaires. This way collected data
is made available to the developers on a webpage
for further development and enhancement of
mobile applications. For evaluating and assessing
this concept, a prototype implementation has been
realized, followed by an evaluation study to analyze
the possibilities and limitations of the developed
model and the associated tools.
