Enrico Costanza, Simon Shelley, John A. Robinson · ePrints Soton (University of Southampton) · 2003
"Audio d-touch " uses a consumer-grade web camera and customizable block objects to provide an interactive tangible interface for a variety of time based musical tasks such as sequencing, drum editing and collaborative composition. Three instruments are presented here. Future applications of the interface are also considered. 1. BACKGROUND Tangible User Interfaces (TUIs) are a recent field of research in human-computer interfaces. Physical objects are used for the control and representation of digital information [1, 2, 3]. Where in a Graphical User Interface (GUI), users interact with virtual objects represented on a screen through mice and keyboard, in a TUI the users physically place and move objects in the real space to achieve the same results. Generally each physical object represents a
