Designing for the Invisible

User-Centered Design of Infrastructure Awareness Systems

Juan David Hincapié-Ramos – jdhr@itu.dkAurélien Tabard – auta@itu.dkJakob E. Bardram – bardram@itu.dk



Infrastructures
Infrastructures

Infrastructures are Invisible!

Problems of Invisibility

  • Use (trust)

  • Adoption

  • Capacity (Mini-Grid)

Vizualizations

Seamful Design

Intelligibility

Problems for Design

  • Future Workshop

  • Paper Protoryping

  • Short Iterations –Evaluations

  • Designing for the Invisible

  • Lack of understanding

    • Nature of the Infrastructure

    • Characteristis

    • Potential

Amc closure
AMC – Closure

  • 15 groups

    • 11 matches

    • 4 missed

  • 13 cards discarted

    • 9 focus

    • 4 nimbus

Matched

The interests can be met

Missed

Either interests orinfrastructure are insufficient

Discarded

Irrelevant for the solution

Results
Results

  • Relevant: machines and people associated to them No Relevant: the details of task distribution.

A

  • To evaluate how relevant is the information displayed by infrastructure awareness systems.

  • Algorithms, input data and parameters

B

  • To identify which of the users interests infrastructures awareness systems do not take into account.

C

  • To identify elements of re-design in the infrastructures themselves so as to improve their adoptability.

  • Task execution results (numeric or graphical)

19


Closure analisys
Closure Analisys

  • Which of the infrastructure features being shown, but not relevant (e.g. bidding activity);

  • Which of the infrastructure features not being shown, but relevant (e.g. the data used to execute a task);

  • Which elements of interest the awareness system could display to engage people even though not supported by the infrastructure (e.g. latest publications).

  • Which elements of the infrastructure were missing to answer users’ interests (e.g. sharing of results).
