In this paper, we introduce our VR system which uses projection, speakers, and a fan to express the distinctive experience of concentration in a Japanese tea ceremony. This system aims to broaden the participant's field of perception (view, hearing, and wind) from a narrow field of view in the tea bowl to multiple sensations of the outside of the tea ceremony room. The continuous concentration, which is presumed by the user's stable motion while mixing tea using a bamboo tea whisk, broadens the field of view and other senses. The accelerometer sensor values of a bamboo whisk were used in an auto-correlation function for detecting the user's stable mixing motion in the tea bowl. In the demonstration experiment in IVRC 2013 (International Virtual Reality Contest 2013), the participants commented positively on the system.
