Recipes for building voice search UIs for automotive

摘要

In this paper we describe a set of techniques we found suitable for building multi-modal search applications for automotive environments. As these applications often search across different topical domains, such as maps, weather or Wikipedia, we discuss the problem of switching focus between different domains. Also, we propose techniques useful for minimizing the response time of the search system in mobile environment. We evaluate some of the proposed techniques by means of usability tests with 10 novice test subjects who drove a simulated lane change test on a driving simulator. We report results describing the induced driving distraction and user acceptance.
