For in-car navigation, information and entertainment
systems, text input is increasingly important. We
investigate handwriting as a text input modality and
assess where to best position the input surface and
how to provide feedback. For this purpose, we created
different prototypes that allow text input on the
steering wheel and in the central console, as well as
visual feedback on the input surface and on the
dashboard. The results of the study indicate that
handwritten text input on the steering wheel is wellreceived
by the users and that the visual feedback
should be presented in the dashboard area or on the
steering wheel. We also observed that the number of
corrective actions and the remaining errors were
significantly smaller (25% less) on the steering wheel
than in the central console and that entering text while
driving made people drive slower.
