TINK - sketching product experiences of connected objects

Testing - 91
session the assignment was reformulated
in a more concrete example.
EXPRESSING AVAILABILITIES
Due to our constant connection to
the internet trough different mobile
platforms and devices, we are always
reachable.
Refusing a call might result in a
bad experience for the caller, but is
sometimes necessary.
How can we notify our availability to
friends and family trough a tangible
interaction?
The participants where asked to brainstorm
on the assignment and design a product
that would solve the given problem. At
the end, they where asked to represent a
system diagram of the designed product on
paper.
3) USE TINK (25min.)
In the third phase the participants had to
use TINK to draw the system diagram for
the product envisioned in the first phase
of the session. Help was provided by the
facilitator just in case the participants got
stuck or when explicitly requested.
4) INTERVIEW (15min.)
Once the participants where satisfied with
their system diagram they were asked
to explain it. An interview was then
conducted to discuss their experiences,
the difficulties they encountered with the
interface and gain feedback on the overall
experience.

2)EXPLANATION OF TINK (10min.)
TINK functionalities where then
demonstrated and explained to the
participants. The roles of the different
entities and building blocks of the TINK
system were described to the participants
and also provided to them in a printout,
which would be available for their reference
in the next phase of the testing.
It was highlighted during the presentation
how important it was to give selfexplanatory
names both to the entities and
to the building blocks.
