The state of the art of map-based mobile services

Abstract

This chapter raises a number of research questions with respect to design issues, interactions and user modelling of map-based mobile services. It gives an overview of the most common mobile user tasks, dominating presentation styles on mobile devices as well as their adaptation forms. The emphasis is laid on usability issues. Depending on whether a usability test is conducted before, during or after the design process, different strategies of user modelling can be applied. The general methods of constructing and evaluating usability tests are also described. Finally, the structure of the book with three theme blocks is outlined.
