Abstract

This paper describes an interactive block device – LED Tile – utilizing 8x8 dot-matrix LEDs which obtain pattern drawing capability. It also applies magnet connectors for physical connections and signal transmissions, as well as interacts with accelerometer sensor and audio signal device. The function of the block device can be defined by the drawn pattern on the matrix LED, and this capability extends the block system applications. In this paper, we describe the hardware and software configurations of this block device, as well as several fundamental and high-level functions of alphanumerical character recognition. We also describe two applications of this device, such as magic square and character arrangement.
