In-Depth Information
Analysis: the plastic system takes into account contextual information to
progressively provide Nathan with a reasonable solution (see Figures 11.7b
and 11.7c).
Moment No. 2
:
Nathan has arrived in Montpellier. His feeling of illness is now
more intense. He prefers to park and go by foot or by any other means available
(bus, tram, etc., depending on the possibilities due to the late hour) to get to the on-
call doctor. Once again, he uses his smart phone to express his query.
Analysis: the plastic system takes contextual information into account in order
to suggest the most appropriate route to Nathan (see Figure 11.8).

11.5. Towards a problem space for the implementation of plastic user
interfaces
Several problem spaces have been proposed for UI plasticity [CAL 07a]. These
spaces identify the key dimensions for supporting the analysis, design,
implementation and/or evaluation of plastic UIs. Figure 11.9 proposes a simplified
version of [CAL 07a]. This version is intended for UI designers. The objective is
two-fold: to help them to imagine innovative solutions; and to think about the
engineering. If this space does not claim to be exhaustive, it nonetheless compiles a
number of questions that have been explored in the literature or that are to be
