Conclusion and Perspective
This thesis provided a broad overview on existing design and development ap-
proaches. By posing a list of requirements we characterized how an ideal develop-
ment process should be composed for innovative application development in ubiqui-
tous and wearable computing.
The X’treme Prototypes have been proposed to ground discussion in concrete arti-
facts. The resulting design evolves in cooperation with various stakeholders which
enhances working relations themselves through shared ownership. In our framework,
it is not the user demanding a solution, but a complementary partnership yields an
innovative result. On the one side, the developers’ part is to illustrate technical
opportunities and limitations by X’treme Prototypes. On the other side the users’
part is to extrapolate from the state of the prototype and to envision new concepts
which are contextually grounded in the user’s work practice. We found that not only
do developers need to get familiar with the user domain, but also the users need
to get familiar with new technology opportunities. Otherwise, they have di culties
in understanding and visualizing future uses and applications the technology might
o er and do not see the potential benefit.
8.1 Evaluation of X’treme Prototyping Characteris-
tics
While developing X’treme Prototyping we aimed at incorporating the requirements,
presented in Chapter 2. The following describes a walk-through of how these re-
quirements have been met.
Early stage support is considered throughout most stages of X’treme Prototyp-
ing. It starts with the deliberate choice of an application domain, then con-
tinues with gaining detailed understanding of the domain. The next step
