Abstract

This paper describes a tangible user interface that uses taps on a hard surface as the mode of interaction between the user and the information device. The surface is constructed by a matrix of small acoustic sensing modules that work together to track both the location of taps on the surface and the rhythm of tap sequences. Each module is also embedded with LEDs to provide visual feedback and novel lighting effects. The system is a generic input/output system and could be used to interface with digital devices. The present prototype of a music wall is one embodiment of the system, implemented as a digital music player. A function set using position-based tap sequence recognition has also been designed to work with music enjoyment on the system.
