Abstract
A 2x2 enhanced Wizard-of-Oz experiment (N = 32) was
conducted to compare two different approaches to
presenting information to drivers in easy and difficult
driving conditions. Data of driving safety, evaluation of the
spoken dialogue system, and perception of self were
analyzed. Results show that the user-modeled summarizeand-
refine (UMSR) approach led to more efficient
information retrieval than did the summarize-and-refine
(SR) approach. However, depending on driving condition,
higher efficiency did not always translate into pleasant
subjective experience. Implications for usability testing and
interface design were presented, followed by discussions of
future research directions.
