Abstract:
Usability and user experience gain more and more attention each year. Many large software companies consider
it a priority. However, domain usability issues are still present in many common user interfaces. To
improve the situation, in this paper we present our design of domain usability metric. In order to design the
metrics, we performed an experiment with two surveys, one in a general domain and one in a specific domain
of gospel music. The results confirm our previous experimental results and indicate, that five aspects of domain
usability are not equal, but have different effect on overall usability and user experience. The results
of the latter survey was used to design weights of domain usability aspects and these weights were used to
calculate the overall domain usability of a user interface. Given that we know the number of all components in
the analysed user interface, the designed metrics measures the domain usability in percentage. The designed
metrics can be use
d to formally measure the domain usability of user interfaces in manual or automatized techniques
and this way, we believe, improve the situation regarding interfaces that do not consider the domain
dictionary of their users.
