usually learn technique by sting the points of himself or between the trainees each
other and this may lead to a resistance or fear to continue further the acupuncture
practice.
A trainee is trained, using the system with force feedback, to master the basic
techniques with tiny force operations such as the methods of stinging, insertion,
holding, and so on. He gets the correct feeling by repeated practice referring the
standard from well-experienced doctors.
Force index was taken from experienced
doctors as an index for operation force training. The results of insertion force vs.
insertion time were plotted in Figure 6 for the Expert doctor. A proper value of 260gf
was obtained after analyzing the experiment results. This value can then be applied as
the standard insertion force as the index used in the system to judge real-timely during
the practice, and the training results are evaluated by the computer.

True-False Judgment in Real Time
A precise judgment of a correct stinging to the proper acu-point position with the
proper force has been difficult in the conventional training method, while it can be
easily and real-timely done with the developed computer system. Using the device with
force feedback on hand movement promotes the training towards the most practical
one. It is also possible to do reliable true-false judgment on a sting using the computer
system, because a beginner is difficult to judge the correct force used to sting into an
acu-point. A trainee gets acupuncture experience not only by visual information, but
also from sensing the force information with a true-false judgment of his movement
being real-timely given during the exercise. The teaching of the tiny force adjustment
in sting was studied with the system, and the results were tested by repeated exercises
of trainees.

Conclusions
In summary of this research, a computer training system for acupuncture with force
feedback functions was proposed. An acu-point model with precise name, position,
flow, sting techniques and healing function, was created on a computer. The
information on each operation, especially the tiny force adjustment was obtained and
