Abstract:
In this work we present the user interaction design process conducted for a mobile product recommender system
that takes the user’s critiques into account. The main focus hereby lies on products, where the appearance
is important. Smartphones reveal additional characteristics compared to desktop systems being devices that
have smaller screens, a direct touch input method and can collect information about the current environment.
The interaction model on which the work builds upon is focused on three key interaction activities between
the user and the system: the initial preference elicitation process, the presentation of the resulting recommendations
set and the preference feedback process. We conduct an interaction design process, involving work
on establishing requirements, designing solutions that meet these requirements, producing an interactive prototype
of the solution and finally, evaluating it in a two-step process. In total eleven designed alternatives,
divided into
three groups according to the interaction activities, were evaluated within a user study, showing
the advantages and disadvantages of each interaction method.
