Voisticky: Sharable and portable auditory balloon with voice sticky posted and browsed by user;s head direction

In this paper, we introduce an effective scheme for browsing and sharing personal voice memos using three-dimensional (3D) auditory space. We proposed an intuitive framework to record and browse numerous personal voice memos using the user´s head directions to post voice memos in user-relative auditory directions for each utterance. The user can define the sharing attribute of each voice memo in the edit mode so that personal and public voice memos are appropriately shared with the permitted users. The shared spaces, which are hemispherical auditory balloons, are overlapped or arranged in separated angles by the number of sharing users. The results of user tests showed that the user could intuitively recognize the existence of whole memos and that there is a possibility of different feelings and cognitions in the voice memos using our proposed scheme compared to conventional voice memos.
