This book represents a part of the work in the SAPMES
project between the Institute for Innovative
Informatics Applications (I3A) at the University of
Applied Sciences Trier and SES-Astra. In this book
the application of a user-centered development
process according to DIN EN ISO 13407 was used to
develop a new graphical user interface for a
Satellite Performance Monitoring System. To support
user-centered development the dialogue principles of
DIN EN ISO 9241 part 110 and the corresponding
generic recommendations assisted to derive usability
requirements. The recommendations for applying the
dialog techniques of DIN EN ISO 9241 parts 14 to 17
helped to derive design solutions from the usability
requirements specified before. The usability of these
design solutions were tested with real users. This
was done with paper prototypes. The results of these
tests were used to improve the specification of the
context of use, the usability requirements and the
iterative design solutions, according to DIN EN ISO
13407.
