ABSTRACT<br />
Driving a car can be a very social activity – especially when a<br />
passenger actively takes part in navigation tasks or operates the<br />
infotainment system. Most available Advanced Driver Assistance<br />
Systems (ADAS) fail to make use of the social nature <strong>and</strong> the<br />
collaborative mechanisms of driving. This paper explores some of<br />
the collaborative dimensions of driving, in order to inform the<br />
design of automotive user interface that helps passengers in<br />
assisting the driver. It presents how we conducted a participatory,<br />
ethnographic study with nine driver-passenger pairs recruited<br />
from an online car-sharing portal. We describe selected findings<br />
we see most relevant to the AUI community: collaborative usage<br />
of navigation devices <strong>and</strong> the speedometer as a trigger for<br />
collaboration. We introduce the acronym ACDAS – Advanced<br />
Collaborative Driver Assistance Systems – as a new term for<br />
systems, which support collaborative activities inside the car. We<br />
argue why, in our designs of future ACDAS, we need to develop a<br />
deeper underst<strong>and</strong>ing of collaboration in general, in addition to<br />
underst<strong>and</strong>ing how <strong>and</strong> in what way other platforms, such as the<br />
mobile phone, will be used in combination with automotive user<br />
interfaces. The notion of a "social car" was provided by the<br />
workshop organizers as cars social entities "socializing one with<br />
the other (similar to how humans are exchanging information)".<br />
We see the car also as a social place, where people are interacting<br />
with each other - either while they are sitting together in a car<br />
(e.g., the driver, <strong>and</strong> his/her passengers in the front- <strong>and</strong> rear-seat<br />
of the car) as well drivers wanting to communicate with their<br />
social peers via Facebook <strong>and</strong> other social services. We will<br />
discuss our findings in this position paper. The collaboration<br />
within the car allows us to investigate the car as a social <strong>and</strong><br />
collaborative place.<br />

1. INTRODUCTION<br />
Most modern cars are now equipped with Advanced Driver<br />
Assistance Systems (ADAS). A car is a ubiquitous computing<br />
mobility device that allows for information access,<br />
communication, media consumption, <strong>and</strong> entertainment. Thus, the<br />
main goal of all ADAS – as the name suggests - is to support the<br />
driver with his primary task. However, these systems in<br />
themselves also hold a risk of distracting drivers. High complexity<br />
<strong>and</strong> dem<strong>and</strong>ing functionality of the ADAS hold as much risk in<br />
distracting the driver. For example, 37% of all traffic accidents are<br />
associated with inattention due to drivers’ engagement in tertiary<br />
tasks, such as mobile phone conversations [6]. Therefore, the<br />
design <strong>and</strong> development of future ADAS is a highly relevant topic<br />
to the automotive community; one solution is to make them more<br />
collaborative <strong>and</strong> socially sensitive.<br />
Driver assistance existed long before ADAS made their way into<br />
the car. Front-seat passengers do not just support the driver in<br />
finding the way to a destination, but also in h<strong>and</strong>ling the radio,<br />
opening snacks, as well as supporting potential backseat<br />
passengers <strong>and</strong> many other tasks. Compared to assistance<br />
technologies, assistance through a human passenger is<br />
conceptually different. On one h<strong>and</strong>, ADAS have advantages over<br />
human assistance in preventing accidents (e.g., automated braking<br />
to reduce the risk of a collision) or in maneuvering skills (e.g.<br />
keeping a safe distance from the vehicle in front). On the other<br />
h<strong>and</strong>, human assistance is superior to technological assistance<br />
systems because humans are more flexible <strong>and</strong> capable of<br />
adapting to a range of conditions. Humans can react to contextual<br />
changes during a journey in a more subtle ways <strong>and</strong> adapt their<br />
assistance according both to environmental <strong>and</strong> social factors.<br />
Furthermore, driving has historically been a social activity. Even<br />
the first cars were not designed only for the driver. As drivers, we<br />
are often not alone in the car, a especially not when going for<br />
longer drives where we are unfamiliar with the route <strong>and</strong>,<br />
therefore, make more use of supportive systems such as the GPS<br />
[5]. In these situations, it is not uncommon that front-seat<br />
passengers help with e.g., reading <strong>and</strong> h<strong>and</strong>ling these assistance<br />
systems. It can clearly be stated that the front-seat passenger has a<br />
very specific role in the car. He is the second closest person to the<br />
driver’s seat, which means he almost has the same access to many<br />
of these advanced systems in the car. Most ADAS are,<br />
nevertheless, neither designed for this kind of collaborative usage<br />
or for being used by front-seat passengers alone. Current ADAS<br />
greatly fail to make use of the collaborative aspects of driving.<br />
Within this paper, we also introduce the acronym ACDAS –<br />
