Auditory browsing interface of ambient and parallel sound expression for supporting one-to-many communication

Abstract

In this paper, we introduce an auditory browsing system for supporting one-to-many communication in parallel with an ongoing discourse, lecture, or presentation. The live reactions of audiences should reflect the main speech from the viewpoint of active participation. In order to browse numerous live comments from audiences, the speaker stretches her/his neck toward a particular section of the virtual audience group. We adopt the metaphor of “looking inside” toward the direction of the seating position with repositioned and overlaid audiences’ voices corresponding to the length of the voice regardless of the seating of real audiences. As a result, the speaker could browse the comments of the audience and show the communicative behaviors when she/he was interested in a particular group of the audience’s utterances.
