'Honda Research Institute Japan Co., Ltd. (HRI-JP), a subsidiary of Honda R&D
Co., Ltd., Advanced Telecommunications Research Institute International (ATR)
and Shimadzu Corporation have collaboratively developed the world`s first Brain
Machine Interface (BMI) technology that uses electroencephalography (EEG) and
near-infrared spectroscopy (NIRS) along with newly developed information
extraction technology to enable control of a robot by human thought alone. It
does not require any physical movement such as pressing buttons. This technology
will be further developed for the application to human-friendly products in the
future by integrating it with intelligent technologies and/or robotic
technologies.
During the human thought process, slight electrical current and blood flow
change occur in the brain. The most important factor in the development of the
BMI technology is the accuracy of measuring and analyzing these changes. The
newly developed BMI technology uses EEG, which measures changes in electrical
potential on the scalp, and NIRS, which measures changes in cerebral blood flow,
with a newly developed information extraction technology which enables
statistical processing of the complex information from these two types of
sensors. As a result, it became possible to distinguish brain activities with
high precision without any physical motion, but just human thought alone.
The BMI technology announced by HRI-JP and ATR in 2006 used a functional
magnetic resonance imaging (fMRI) scanner to measure brain activities. The large
size and powerful magnetic field generated by the fMRI scanner limited the
locations and conditions where it can be used. As the newly developed measuring
device uses EEG and NIRS sensors, it can be transported to and used in various
locations.
Test procedures for experiments with the new BMI
First, EEG and NIRS sensors are placed on the head of the user. Then, one of
four pre-determined body part options is provided to the user. The user imagines
moving that body part without making any physical movement. Changes in both
brain waves and cerebral blood flow triggered by the brain activity are measured
simultaneously. The data obtained are analyzed on a real-time basis to
distinguish what the user imagined. Upon receiving the result, Honda`s ASIMO
humanoid robot makes corresponding movements such as raising its arm or leg. The
world`s highest level accuracy rate of more than 90% was achieved in the tests.
Since 2005, Honda and ATR have been conducting research and development of BMI
technology exploring the potential of a new interface which connects people and
machines. Honda is looking into the possibility of applying this technology to a
people-friendly human interface through integration with other technologies such
as artificial intelligence technologies and/or robotics technologies. In May
2006, Honda and ATR successfully developed a BMI technology which utilizes a
fMRI scanner and achieved the first success in the world to control a robot hand
by decoding brain activities without electrode array implants or special
training of the user.
About BMI
While conventional machine-interface uses devices such as switches which need to
be operated by a user`s hands or feet, BMI uses brain activity data measured by
various devices and enables non-contact control of the machines (such as
robots). Invasive BMI, which is widely studied by U.S. and European researchers,
requires the surgical implant of electrode arrays, whereas non-invasive BMI uses
sensors touching the user`s scalp.
