OVERVIEW

As the functionality of AV equipment improves and the number of TV broadcast channels increases, the era in which we "can't pick and can't watch" our preferred programs is approaching. In addressing this problem, Hitachi has developed an "intelligent user interface"—which uses "multimodal dialog control" to help users (i.e. viewers) operate home AV equipment by means of spoken dialog. Integrating speech information processing, image information processing, and a TV program recommender based on viewing-history analysis, this multimodal dialog control can partake in dialog with the viewer. Without the need for keyword entry, the TV program recommender automatically analyzes the viewer's program preferences from their past viewing history, and then selects, recommends, and records certain programs according to the analysis results. Utilizing voice information processing, this intelligent user interface can operate AV devices via spoken dialog very close to everyday conversation. It can also distinguish different viewers by facial image recognition and automatically change the offered services (such as the TV program recommender) to match the preferences of whoever is in front of the TV.
