Perception changes with and without a video channel: A study from a speech-to-speech, machine translation mediated map task

摘要

This study looks into the effect of the video channel, that provides realtime visual information of the subject's inter-locutor in computer mediated multi-lingual map task dialogues. The addition of a video channel in long distance audio communication has been commercially available since 1964, pioneered by AT&T's Picturephone. However the complexity of adding an image channel to a task oriented dialogue has not penetrated the user audience enough to change the user expectation from a like-to-like alternative of Face-to-Face communication, to a new different communication style. This study reports the increase in visual cognitive state occurrences when communicating with a video channel and the different perception that this setting provided to the subjects of the ILMT-s2s corpus.
