  <Problems and Strategies>

At present, exercise training is based on a "Qualitative" instructions or assessments based on the experience of training providers. Thus, standardization of training program cannot be achieved.


Main concepts of exercise rehabilitation is to 

  (1) Evaluate the maximum tolerance limit such as distance, weight, or speed.

  (2) Then, train to get above the limit and evaluate the achievement rate and feedback.

  (3) Ideally, with stimulating cognitive function simultaneously.


We think that virtual/augmented/mixed reality technology in combination with 3-dimensional tracking systems can achieve this goal objectively.  Artificial intelligence technology can provide tailor-made program for each patient without human resources in near future.
