Inspired by traditional Japanese fan dancing Shibu, also known as Senbu, the real-life dancing program captures hand movement and renders the motion of a fan. Based on the speed of the dancer’s movement, the fan opens during high-speed movement, tracing a smooth and silky surface in the air; during slower movements, the fan closes, as is represented by the boxes. Several versions of Shibu were tested out: one is based on a given speed, and one renders open-fan motion as a uniform loft surface. The final product calculates the average speed of the dancer’s hand movements and depicts open-fan motion in an amplitude modified by speed.
