Predicting Who Will Be the Next Speaker and When in Multi-party Meetings
***Abstract***
An understanding of the mechanisms involved in face-to-face communication
will contribute to designing advanced video conferencing and dialogue
systems. Turn-taking, the situation where the speaker changes, is
especially important in multi-party meetings. For smooth turn-taking,
the participants need to predict who will start speaking next and to
consider a strategy for achieving good timing to speak next. Our aim is to
clarify the kinds of behavior that contribute to smooth turn-taking and to
develop a model for predicting the next speaker and the start time of the
next speaker's utterance in multi-party meetings. We focus on gaze behavior
and respiration near the end of the current speaker's utterance. We
empirically demonstrate that gaze behavior and respiration have a relation
to the next speaker and the start timing of the next utterance in multi-
party meetings. A prediction model based on the results reveals that gaze
behavior and respiration contribute to predicting the next speaker and the
timing of the next utterance.

Feature Articles: The Challenge of Creating Epoch-making Services that
Impress Users

Creating Epoch-making Services that Excite Users
***Abstract***
When the telephone first made it possible for people to chat with friends
hundreds of miles away, and when the Internet made it possible to obtain
thousands of books' worth of information without having to visit a library,
people were excited by these technological advances. NTT Service Evolution
Laboratories has set itself the challenge of developing technologies for
the creation of new services that will generate as much excitement as the
phone and Internet did. This article presents an overview of our work.

Developing Technologies for Services that Deliver the Excitement of
Games Worldwide
***Abstract***
NTT Service Evolution Laboratories has floated the concept of an ultra-high
-presence service that will enable viewers to experience the feeling of
actually being in a sporting venue or the like, wherever they are, and is
therefore developing an immersive telepresence technology called Kirari!,
towards its implementation. This article introduces the supporting
technologies used with Kirari!, which involve ultra-high-presence media
generation, spatial and environmental information synchronized delivery,
and content license management.

Personal Agents to Support Personal Growth
***Abstract***
We at NTT Service Evolution Laboratories have been focusing on implementing
a personal agent that will co-exist with us in the real world, empathize
with us, encourage us to stay active, always be at our side to support our
personal growth, and even grow on its own. In this article, we introduce
sensing technology for understanding people and their environment;
multimodal interaction technology for supporting people and helping them
to grow; and virtualization technology for implementing device features
that are used to continuously support people in any place or at any time.

Proactive Navigation Optimized for Individual Users
***Abstract***
In this article, we first give an overview of the proactive navigation
project that NTT Service Evolution Laboratories is striving to accomplish.
Then we provide a simple explanation of the technologies currently being
researched and developed to implement the project: information navigation,
big data analysis, and resilient communication. Finally, we give an overview
of experiments currently being run in Fukuoka City along with their results.

Towards the Creation of Attractive Services Based on an Understanding
of Users
***Abstract***
To create information and communication technology services that are fun
for users, it is necessary to ensure that such services match user needs
and characteristics, and to do this, we need to fully understand users.
We introduce here the processes involved in service creation and the design
area that NTT Service Evolution Laboratories is focusing on. We also show
a specific example of what we do to understand the user and visualize
a service image.

Creating Omotenashi Services for Visitors and Spectators in 2020
***Abstract***
NTT Service Evolution Laboratories is working to develop services for
people from both within and outside the country who will visit various
places in Japan. This includes the spectators and organizers who will be
in Tokyo for the 2020 Olympic and Paralympic Games. This article describes
four conceptual Omotenashi services that will be available on smartphones
and tablets to provide people with spectator and transportation assistance.

Efforts toward Co-Innovation Promotion
***Abstract***
NTT is now shifting its business model from the conventional B2C (business-
to-consumer) model to the B2B2C (business-to-business-to-consumer) model in
order to create novel services in alliance with various external players.
This article introduces the Co-Innovation Promotion Project that was
launched at NTT Service Evolution Laboratories to promote partnerships
with them.

Taking the English Exam for the "Can a Robot Get into the University of
Tokyo?" Project
***Abstract***
NTT and its research partners are participating in the "Can a robot get
into the University of Tokyo?" project run by the National Institute of
Informatics, which involves tackling English exams. The artificial
intelligence system we developed took a mock test in 2014 and achieved a
better-than-human-average score for the first time. This was a notable
achievement since English exams require English knowledge and also common
sense knowledge that humans take for granted but that computers do not
necessarily possess. In this article, we describe how our artificial
intelligence system takes on English exams.

Cross-connect System with Packet Transport Technology
***Abstract***
The public switched telephone network (PSTN) and existing dedicated line
services have been carried over transmission lines using older data link
systems based on time-division multiplexing technology. However, as
Internet protocol traffic has increased and traffic to the PSTN and
existing dedicated services has decreased, there has been a move to use
data link systems based on packet transport technology; this in turn has
allowed simpler networks to be built. We have developed a packet-based
cross-connect system that can efficiently promote this transition by
allowing individual low-speed (1.5 Mbit/s) paths to be split up and
reassembled.

Recent Activities of ITU-R Study Group 5
***Abstract***
Radiocommunication systems such as mobile communication systems and fixed
wireless communication systems play important roles in telecommunication
networks. Mobile communication systems have become widespread, as
represented by smartphones, and fixed wireless communication systems
provide flexible and resilient communication in times of disasters. The
International Telecommunication Union - Radiocommunication Sector (ITU-R)
is one of the organizations responsible for developing standards for these
important systems. Towards the end of 2015, the ITU-R will hold two very
important meetings: the Radiocommunication Assembly (RA) and the World
Radiocommunication Conference (WRC). This article introduces recent
activities and contributions from NTT and NTT DOCOMO to ITU-R Study Group 5,
which deals with terrestrial radiocommunication systems.
