In this paper, we propose OptRod, a shape-free and multifunctional display system operated by projected images. A PC generates images as control signals and projects them to the bottom of OptRods by a projector or LCD. An OptRod receives the light and converts its brightness into a control signal for the attached output device. By using multiple OptRods, the PC can simultaneously operate many output devices without any signal lines. Moreover, we can arrange surfaces of various shapes easily by combining multiple OptRods. OptRod supports various functions by replacing the device unit connected to OptRod.

This paper introduces a display technique to show gradation animation using a shape-changing artificial grass system. Recently, liquid crystal displays and projectors have been used in a natural public facility, such as a park, but their artificial appearance can spoil the natural scenery. The proposed method is useful for developing a natural landscapefriendly display. We developed a grass pixel system to display the gradation. The grass pixel consists of yellow and green grass, and the length of the green grass moves vertically. The grass pixel uses a pin-based shape-changing system using a stepper motor to control the grass length dynamically. We evaluated the grass pixel gradation using an image processing of HSV (Hue, Saturation, Value of Brightness) values. In the measurement, the pixel system moved the grass length from minimum to maximum, and we took images of the running grass pixel from several angles. As a result, we observed that the HSV values changed linearly with the movement of the length of the green grass. We also developed a 3 × 3 pixels grass display, which can demonstrate several gradation animations.
