We would like to contribute to a smart society that
enjoys healthy longevity through AI technology that
supports training to make subjective skill up.
• In order to extend healthy life expectancy, training to
maintain physical functions and skills is necessary.
• To tackle sustainable skill-up training, it is important to
support independence and voluntariness.
• It is difficult to grasp personal skill.
• Training tasks are not based on evidence but are
subjectively determined by interpretation.
• The trainee can not realize the training effect.
Too difficult
Too easy Tired
Not motivated
Difficulty of voluntary skill-up support
When wrong tasks are given:
Collaboration with
• Retirement community for
elderly people (Sun City)
exists in the city.
• Needs for improving QOL
of elderly by facilitating
excise.
• 1st place of Most
Innovative Schools in U.S.
by News and World
Report (2015-17)
• Collaboration with Center
for Cognitive Ubiquitous
Computing (CUbiC)

The purpose of this research is to develop "AI smart
coaching technology to promote voluntary skill
enhancement" by simple and small number of
wearable sensors and individual skill grasping
technology.
AI smart coaching technology
1. Developing assessment system of user's
skill
2. Developing determination system of
task difficulty level
3. Developing smart coaching system
• Skill evaluation by wearable sensing, and motion
estimation by digital human model
• Proper task presentation by skill segment
• Development of artificial muscle training suits and training
software that can present task difficulty according to skills

2. Developing determination system of task difficulty level
We will define physical effort from
physical load by using a
musculoskeletal simulation and set
the task level based on the physical
effort.

Application to rehabilitation and special skill coaching and data accumulation
We will develop flexible and
lightweight artificial muscle suits,
training software with an intuitive
user interface, and verify the effect
for rehabilitation and special skills.
PAM-basedtraining
• Use lightweight, flexible, and inexpensive low-pressure
driven pneumatic artificial muscles (PAMs)
• A training suit that can be used at home as an extension
of clothes
• Maintain effective load by control the physical load
depending on the recovery condition of the user

3. Developing smart coaching system
• A user interface that makes it possible to continue
rehabilitation and training that tends to be tired.
• Utilizing non-contact sensors realizes easy measurement
of the user motions
• Utilizing the developed AI core technology, AI will
automatically judge the tasks given to users depending
on individual skills

• In the lead research period, we will develop an effective
rehabilitation support system by linking the motor function data to
functional independence evaluation (FIM).
• The final goal is to develop an AI system that can be specifically
applied to special skills and to suggest work that will be made
possible by training.
Potential applications
1. Developing assessment system of user's
skill
2. Developing determination system of
task difficulty level
3. Developing smart coaching system
Toward smart society to enjoy healthy long life
We will contribute to a society that enjoys healthy longevity by:
• Improve independence of elderly and disabled people with technology that can
be used at home
• Extension of healthy life span by effective and efficient care for individual
• Reduce social security and medical expenses with securing manpower in aging
