Abstract

The development of an in-store sales support system that focuses on the "virtual try-on" of clothing is the main goal of the research project "IntExMa". Within this scope we investigate to what extent mobile devices can support the tasks of the retail sales staff in their daily personal sales activities. In doing so, usability is regarded as the central quality criteria. This paper addresses the resulting question, how a user-friendly design of, in our case, a PDA is characterized. We introduce a compilation of seventeen design principles and detail each with a range of exemplary rules to facilitate practical applicability.
