  Dear Joelle, dear all

please find my comments below:

 >> **** Cell Task&Concept-Design Time: actually, there are 2 use cases here :
 >> - UC3- "Car rental" provided by UCL. Motivation: it has been decided that it will be used as the running example for 
every chapter.

- the example provides an elaborated diagram of different model re-combinations,
   though examples of corresponding "context information" and resulting adaptation scenarios
   should be added

- I support the way to concretely/formally describe the artefacts in question
   (informal list of) tasks and the domain model. Will the other layers/models be covered as well?

 >> - UC1- "Digital home" provided by ISTI. Motivation: it is well described, easy to understand, and very timely in the 
scientific, technical, and industrial communities.

- though this UC references usage of the task model, its "design-time" relevance is not apparent to me, does the
   mentioned filtering of the underlying "nomadic CTT task model" take place at design or runtime ?

- the UC has a broad, general coverage of possible/prospective MBUI solutions for digital homes and uses often
   a conditional langauge ("should/will be expressed..."). Possibly the focus could be narrowed to a single example
   and have a final wording ?

 >> - Reasons for not selecting the other UCs: UC5 (Usability engineering) and UC10 (Learning HCI) are presented in 
generic terms; no screen dump of the FUI has been provided;

  UC5 has a strong orientation on (high-level) models and early prototypes (generated out of these models). When
  re-phrased, this could be a good UC candidate for TM/Design time perspective. It could elaborate on aspect of model
  acquisition (how does domain/task analysis and usability consideration) map to e.g. task model, and aspect of (static)
  model transformation and prototype generation ..


 >>
 >> **** Cell Task&Concept-Run Time
 >> - UC4 "Minimalist UI" provided by DFKI. Motivation: it is well described, applies to large scale industrial domain, 
covers the "environment aspect" of the context of use.

- I have some doubts whether there is any UC illustrating task model adaptation at runtime ?
   UC4 describes the generation of an unified UI for a variety of devices and thus implies the usage of
   different task models, but this aspect should be elaborated further ?

- proprietary models mentioned here should be mapped onto the MBUI/Cameleon-stack:
       "dialog model"
       "adaptation model" (adaptation rules)
       "presentation model"


 >> **** Cell Concrete UI-Design Time
 >> The 2 use cases proposed for this cell, UC6 (automotive industry approach) and UC11 (multi-device development tools) 
are generic descriptions/discussions about methods and tools respectively. They are not specific instances of either an 
approach used by such and such automative company for UC6, nor the description of a specific multi-device dev. tool. 
such as PhoneGap for UC11. In short, UC6 and UC11, as currently presented, are not use cases per se. Decisions have to 
be made by the group and/or by the contributors.

  Maybe UC5 is a candidate: prototype generation at design time (for the purpose of iterative development) ?


**** Cell Concrete UI-Run Time

  - UC7.3 remains a strong candidate, though:
  - the model diagram does not reflect the whole context of use: user (session data, gestures etc.)
    and environment (interactive room, light conditions etc.)
  - surprisingly the CUI-model (platform-dependent layer) is not being re-organized (branching only
    at FUI (implementation language level) ?

 >>
 >> **** Cell Final UI-Run Time
 >> - UC2 (migratory PACMan) demonstrates automatic total migration between devices.

  - my vote for UC2

  Many thanks for your effort, best regards
    Jaroslav

In addition the UI is expressed in German, thus not accessible to any one. UC10 (dynamic composition of UI) is quite timely and well described, probably too advanced (academic) for readers newcomers in the field. Can be discussed in comparison with UC4.

>> Both of them are well described. PACMAn is a well-known and very successful game, thus easy to understand by our readers. On the other hand, TWS is a representative of many web sites, and thus may have more interest to advanced readers. Decision has to be made by the group (vote).
