Abstract
In this paper, we address the question how speech and tangible
interfaces can be combined in order to provide effective multimodal
interaction in vehicles, taking into account the special
requirements induced by the circumstances of driving. Speech
is used to set the interaction context (determine the object as is
to be manipulated) and a turn-and-push dial is used to manipulate/
adjust. An experimental study is presented that measures
the distraction induced by manual (conventional), speech-only,
and multimodal interaction (combination of speech and turnand-
push dial). Results show that while subjects where able to
perform more tasks in the manual condition, their driving was
significantly safer while using speech-only or multimodal dialog.
Supplemental contributions of this paper are descriptions
of how a multimodal dialog manager as well as a driving simulation
software are connected to the CAN (Controller Area Network)
vehicle bus as well as how driver distraction caused by
interacting with a system are measured using the standardized
lane change task (LCT)
