Keywords:Hyoh-Joh, Embodied Knowledge

Before we perceive the world as a static and insipid entity, we experience it as an 'expressive' world, perceiving the 'Hyoh-Joh' of the world, as Hiromatsu (1989) argued. Hyoh-Johs are the "totality that the object in motion brews for the subject," analogous to those of the face. This concept is considered to resonate with Oka's "Joh-Cho" thought. The author focuses on the activity of "practitioners learning body movement expression, appreciating their own and others' moving bodies" and has developed an app to encourage viewers to perceive 'Hyoh-Johs'. This app draws "moving/changing figures (Hyoh Joh forms)" on the three-dimensional space on the screen, using the measured body movement data (position coordinates of each joint point) as vertices. Users are encouraged to "edit and appreciate" the Hyoh-Joh figures intuitively and to reflectively describe their experience. What kind of Hyoh-Joh forms are desirable, or what kind of editing should be encouraged for the user? While a firm answer has not yet been obtained, a hypothesis has been formed that figures preventing the positions of parts from changing drastically akin to a 'face', emphasizing the relationship where each point or line is invariably related to others such as represented by Delaunay triangulation, are preferable.
