Abstract:
Usability implies effective, efficient and satisfactory interaction with a system when using it. Similar
properties are not usually considered when an end user is faced with evolutionary developing or improving a
system – an activity increasingly more often, particularly when the context of using a system undergoes
frequent and significant changes. Project Nomadic Media investigated possibilities for user-participative,
effective, efficient and satisfactory evolution of nomadic systems. We considered geographically
distributed, context-sensitive, personalized systems, exploiting various web services and allowing for a
general function referred to as nomadic blogging. In this paper we demonstrate general policies of evolution
and the specific ways of end-user interaction with the evolving system. The overall strategy may be
generally described as simplicity – effective with clear and straightforward goals, efficient in terms of
resources spent at each small evolutionary deliv
ery step and satisfactory in terms of end-user participation
and reaching the explicit planned user targets. Results of experiments with such systems are demonstrated.
