Abstract
This work is a sound installation that utilizes the surrounding human flow information to dynamically transform the visual and auditory expressions of a ‘Hokora’ integrating changes in light, shadow, and music based on the movements and tendencies of people, ultimately creating an interactive environment where the shrine and individuals mutually influence each other. ‘Hokora’ is a miniature Shinto shrine on a street side, and in Japan, it is a common practice to stop or bow when passing by. Through the faith in the shrine, the environment, or human flow, also undergoes changes. In this work, the information from the surrounding human flow is reflected in the presentation of light and shadow reminiscent of dappled sunlight, causing the visual and auditory expressions of the Hokora to change based on people's actions and further influencing the environment. In this work, three ultrasonic distance sensor values are used as input, and the detection frequency and distance values of the past 10 detections are recorded for each sensor. The recorded detection frequency is used to calculate the congestion level of the surrounding human flow. Based on these two pieces of human flow information, changes are introduced in the movement of lights controlled by motors (DC and servo), creating shadow play and altering the music output. This contributes to the portrayal of light inspired by dappled sunlight. The density of human flow influences the left and right movement of lights, reflecting the intensity of the light's movement. On the other hand, in the realm of music, the density of human flow modulates the frequency of high-pass and low-pass filters. By offering viewers an expression of the Hokora that changes based on human flow information, this installation creates an effect where the Hokora and people mutually influence each other, a phenomenon not traditionally seen in Hokora.
