Abstract

This paper describes an interactive block device with dot-matrix LED, with capabilities of drawing patterns by lights, physical and signal connections of devices with magnet connectors, and interaction using accelerometer and sounder. The pattern drawing is implemented by the technique of using matrix LEDs as light sensor array, which saves the additional hardware cost. Three applications of this block device, pattern morphing, function definable block, and musical box, are also described.
