Cluster-based tangible programming

Clustering is the act of grouping items that belong together. In this paper we explore clustering as a means to construct tangible program logic, and specifically as a means to use multiple tangible objects collectively as a single tangible program parameter. We introduce T-logo, a simple tangible programming environment developed to test the concept of cluster-based programming. Although the principle of cluster-based programming is technology agnostic, we describe it here by means of a vision-based system. We further introduce the concepts of Cluster Marker, Cluster Marker Position, and Cluster Marker Zone to describe the principles on which cluster-based programming is based.
