Abstract:
As part of research toward establishing voice communication media that
shall replace telephone, we developed an architecture and a prototype
of a continuously-connected multi-user communication medium called
voiscape. A virtual "sound room" that is created by spatial audio
technology is used in voiscape. When the user moves within the sound
room by using a mouse, the presence information including the position
in the room is distributed to other users of the room. If the user
becomes closer to or more distant from another user, the communication
session begins or ends automatically by using SIP according to
predefined policy stored in the terminals. This policy-based session
control enables privacy protection and reduction of communication.
When a local site requires a session start, the remote site often
requires a session start concurrently, so a method of establishing a
connection without connecting doubly nor becoming busy was deviced.

Abstract:
The concept of a new communication medium called voiscape is proposed.
A virtual "sound room" that is based on the spatial audio technology
is shared among the users in voiscape, and a person can move freely in
the room, can meet and depart from other people, and can talk with two
or more persons by using voiscape. By enabling transmission of presence
and peripheral information, voiscape will cover from a telephone-style
one-to-one conversation to a variety of communication types that are
impossible in conventional media, and will enable sharing the feeling
of connection and releaf and sharing tacit knowledge. This paper
describes usage scenes and a procedure of voiscape and also describes
a PC-based prototype. In this prototype, the user can confirm the
situation in front by 3D graphics, and can move around the room by
using a mouse.
