NeuroDialog: an EEG-enabled spoken dialog interface

Understanding user intent is a difficult problem in Dialog Systems, as they often need to make decisions under uncertainty. Using an inexpensive, consumer grade EEG sensor and a Wizard-of-Oz dialog system, we show that it is possible to detect system misunderstanding even before the user reacts vocally. We also present the design and implementation details of NeuroDialog, a proof-of-concept dialog system that uses an EEG based predictive model to detect system misrecognitions during live interaction.
