6. // QUESTIONNAIRE
Each interviewee, before the interview,
was invited to fill in a questionnaire that
allowed us to gather very useful
information about their personal profile
useful for identifying possible influences
in the answers.
The questionnaire showed 66% of
interviewee are usual to drive the car
mostly alone, without passengers.
Moreover we verified that even older
interviewees have a fair confidence with
technological devices.

mentioned, is to facilitate the
accomplishment of some activities the

31. // METHODOLOGY
HEURISTICS ANALYSIS //
In order to improve the system usability,
we conducted an heuristic analysis,
checking the system performances
related to these topics:
1. Visibility of system status
2. Matching system and real world
3. Standards and consistency
4. Error prevention
31
32. // VISIBILITY OF THE SYSTEM STATUS
HEURISTICS ANALYSIS //
1. Visual hints to show the active status 2. Speedometer is clearly visible

33. // VISIBILITY OF THE SYSTEM STATUS
HEURISTICS ANALYSIS //
3. Top bar 4. Navigation status

34. // MATCHING SYSTEM AND REAL WORLD
HEURISTICS ANALYSIS //
1. Real world references in icons 2. 3D navigation system

35. // STANDARDS AND CONSISTENCY
HEURISTICS ANALYSIS //
1. Icon design is coherent between
screens
2. Coherent color palette between screens
3. Coherent fonts

T2: Telefone function
Telephone is represented by
a handset (here we could, in a
future research, ask for the
interviewee to choose from a
smartphone, a cell phone and
a handset, because we think
that in the future the handset
of the telephone will be
culturally obsolete).
