Physical skills such as playing the musical instrument are hard to learn and take long time
to master. To investigate what makes physical
skills so dificult to learn and how we can evaluate the level of skills, we examined the kneading
in ceramic art, an action to prepare the clay for
shaping and studied the physical movements of
both the learners and experts.
Kneading is an appropriate sample of physical
skill for studying the body movement because all
the parts of body need to be coordinated to accomplish the task. The task is not hopelessly difficult for the complete novices to follow the instruction although the end result is not satisfactory.
It normally takes about three years to master the
kneading skill. It is also relatively easy to judge
how well the subjects accomplished the task by
observing the shape of the clay.
After careful examination of the movement using video tapes, we employed a motion capture
device to collect the data of movement from an
expert, an experienced person, and three novices.
We discovered that the expert elegantly splits his
body into two parts, torso and arms, and effectively coordinates these two parts while kneading
the clay.
