Research Institute of Electrical Communication Tohoku University


Taking advantage of the wide range of research expertise in the institute, ad-hoc research groups are formed outside of the formal organizational structure to investigate challenging exploratory topics and needs-based, cutting-edge subjects.

Group of multimodal attention

Satoshi Shioiri (Group Leader)
Shuichi Sakamoto
Kazumichi Matsumiya
Nobuyuki Sakai
Kosuke Yamamoto


Attention spreads over a limited range in the visual field as the spotlight metaphor suggests and similar attention effect is investigated for auditory and tactile perception. We investigate spatial spread of unimodal and multimodal attention using steady state visual/auditory/tactile evoked potential through electroencephalogram (EEG) measurements in order to model attention modulation for unimodal and multimodal perception.


Cyber-Physical Security Research Group

Naofumi Homma (Group Leader)
Takuo Suganuma
Takahiro Hanyu
Atsushi Ohori
Noriharu Suematsu
Takafumi Aoki
Nei Kato
Hiroki Shizuya
Hideaki Sone
Akinori Ito
Shin-ichiro Omachi
Toru Abe
Masanori Natsui
Suguru Kameda
Katsuhiro Ueno
Hiroki Nishiyama
Takaaki Mizuki


For the next-generation information and communication infrastructures such as IoT, M2M, and CPS, we aim to developing information security technologies to ensure security and reliability at the level of vast and diverse information sources (i.e., embedded devices such as sensor terminals) in a vertically integrated manner from the viewpoints of software constitutive theory, system security, hardware security, circuit architecture and next-generation micro processor.


Brainmorphic Nano-Devices and Circuits Research Group

Yoshihiko Horio (Group Leader)
Shigeo Sato
Shunsuke Fukami
Takahiro Hanyu
Masanori Natsui
Ayumi Hirano-Iwata
Hideaki Yamamoto


Brain-inspired hardware systems have been actively developed recently. However, a big break-through to the true brainmorphic system has not been reached yet.
This research group aims at development and implementation of novel brainmorphic computational hardware that reproduces the bio-physics and dynamics in the brain directly through dynamics and physics of nano-devices and ultra-low-power integrated circuits based on the latest physiological knowledge.


AI Clone Research & Development Group

Satoshi Shioiri (Group Leader)
Masanori Hariyama
Yoshimi Suzukamo
Yasuhiro Hatori


The aim of the group is to realize “AI clone”, which is the model of recognition and action characteristics of a person, by adopting knowledge of the cognitive science in an AI technology. AI clone is to enable others to re-experience the target person’s recognition and action with virtual reality technologies. Our goal is to develop the new communication technology to improve mutual understanding among people with differences in a variety of aspects, using AI clone and AR interface.
