2. Usability, Utility and User Experience Usability = how easy
and pleasant a product is to use Utility = whether the product
provides the features you need Useful = usability + utility An
expanded definition:User Experience Supports creativity Efficient
Easy to rememberHas good utility Safe HelpfulSatisfying to use

3. User Experience FrameworkWellings, T., Williams, M.A. &
Pitts, M.J., (2012). Characterising the experience of interaction:
An evaluation of automotive rotary dials. Ergonomics, 55 (11),
1298-1315. UX Camp 2012 | [email protected]
4. Why is user experience important? Safety: Driver distraction
when using In Vehicle Information Systems (IVIS) is correlated with
crash risk Brand reputation - Poorly resolved technology has large
negative impact on customers view of automotive brands (e.g. BMW
iDrive, My Ford Touch) Customer satisfaction Problems rates are up
18% for audio, entertainment, and navigation systems since the 2010
JD Power IQS survey, and up 28% since 2009UX Camp 2012 |

6. Maximizing initial sales or maximizing long-term customer
satisfaction? Consumers know that products with more features are
harder to use, but before purchase they value capability more than
usability. Even when consumers are allowed to customize a product,
they load on the features, worrying little about the learning curve
they are setting for themselves. Once consumers have used a
product, their preferences change. Suddenly, usability matters more
than capability. Rust, R.T., Thompson, D.V. & Hamilton, R.W.,
(2006). Defeating Feature Fatigue. Harvard Business Review, 84 (2),
98-107. UX Camp 2012 | [email protected]

8. Current reality mostly Familiar and easy to use Muscle
memory and kinaesthetics Users benefit from direct access to
frequently used features through hard buttons. E.g. audio volume,
HVAC temperature, driving dynamicsUX Camp 2012 |

10. The demise of hard buttons? Trend from mechanical to
membrane switches to Secret until lit proximity sensing switches.
Issues for increasing visual demand - little or no haptic component

11. Dont speak too soon This is an emotional subjectI love what
you've become Cadillac, and I only want good things for you, but if
you can't give me actual buttons with tactile feedback that I can
use while watching the road, I'm afraid it's over between us.UX

12. Switch quality and the user experienceThe overall appeal of
the sensory interaction is dependent on the Positivity/Precision of
the dials, and their (lack of) Unrefined Loudness.Wellings, T.,
Williams, M.A. & Pitts, M.J., (In press). Characterising the
experience of interaction: An evaluation of automotive rotary
dials. Ergonomics. UX Camp 2012 |

Information Systems (IVIS) are not websites Safe operation is
criticalAudi Electric R8 ConceptUX Camp 2012 |

14. Changing legislation Research by The U.S. National Highway
Traffic Safety Administration (NHTSA) has shown: > 17 percent of
all police-reported crashes in 2010 reportedly involved some type
of driver distraction. > Of these, 26,000 accidents were caused
by distraction from "a device/control integral to the vehicle such
as a navigation or infotainment system. New guidelines aim to limit
the use of in-car technology that is "not directly relevant to
safely operating the vehicle, or that causes undue distraction." US
Department of Transportation, (2012). Visual-Manual NHTSA Driver
Distraction Guidelines for In-Vehicle Electronic Devices.

15. Categorising driving-related functions: critical vs.
non-critical How do you classify which interaction tasks are
directly related to the driving task? Is this relationship of the
same importance in all situations? Contextual awarenessUX Camp 2012

16. Personalisation Cockpit technology has emerged as a leading
differentiator when considering and purchasing an automobile for
young adult consumers (Deloitte, 2011). Downloadable in-car apps?
Social media updates? Personalised menus with shortcuts to
favourite features Differences between younger and older customers?
More research needed on the safety implications of user-modified
interfacesUX Camp 2012 | [email protected]
17. Multimodal user interfaces Used alongside other forms of
input interfaces Hand writing recognition Will legislation make
these interfaces redundant?UX Camp 2012 |

20. Summary Automakers must keep in-vehicle infotainment
systems fresh with new content and features, achieve seamless
integration with mobile apps and devices, create personalized user
experiences, and accelerate their development cycles to keep pace
with the expectations of the connected consumer. And, somehow, they
must achieve all this without compromising safety and reliability.
