Title
Could a dialog save your life?: analyzing the effects of speech interaction strategies while driving
Abstract
We describe a controlled Wizard-of-Oz study using a medium-fidelity driving simulator investigating how a guided dialog strategy performs when compared to open dialog while driving, with respect to the cognitive loading these strategies impose on the driver. Through our analysis of driving performance logs, speech data, NASA-TLX questionnaires, and bio-signals (heart rate and EEG) we found the secondary speech task to have a measurable adverse effect on driving performance, and that guided dialog is less cognitively demanding in dual-task (driving plus speech interaction) conditions. The driving performance logs and heart rate variability information proved useful for identifying cognitively challenging situations while driving. These could provide important information to an in-car dialog management system that could take into account the driver's cognitive resources to provide safer speech-based interaction by adapting the dialog.
