A between-participants (N=60) experiment explores the effect of input modality (voice with 100% recognition vs. remote) and culture (US vs. Japan) on user's opinions of an Interactive High Definition Television System (iHDTV). There was a significant interaction: .Japanese participants completed tasks more easily and thought the interface was better with a remote control. Conversely, United States participants completed tasks more easily and thought the interface was better with voice control. Participants from both cultures liked content more and felt more uncomfortable when using voice control.
