Automotive User Interfaces and Interactive Vehicular Applications

PERSONAS FOR ON-BOARD DIAGNOSTICS
USER TYPES OF DRIVERS DEALING WITH MALFUNCTION IN E-CARS
WHAT? www.tu-ilmenau.de WHY? HOW?
This work focuses on identifying user types
of drivers dealing with malfunction
in electric cars. Therefore, personas have
been developed within the research project
PräDEM (Predictive Diagnosis of
Electric Motors in automotive drives).
For me, my car is only an object of everyday
use. On error, I just want to know
how bad it is and what to do. The small
error lights are absolutely cryptic for me.

The personas served as a concrete design
goal and means of communication
for the development and evaluation
of an ergonomically high-quality
display and interaction concept for predictive
On-Board-Diagnostics in electric cars.

Expectations: high information content,
competence building
I enjoy driving the car and I am interested
in the technology behind it. I understand
error messages of my car,
but find them too little informative.

An expert round and four focus groups with
drivers identified typical behavior patterns
which were validated by surveys. As a result
we got three personas of On-Board Diagnostics,
which can be used for a more usercentered
design of such diagnosis systems.
