Abstract

This paper presents a novel paradigm for prototyping Computer Vision algorithms; this paradigm is suitable for students with very limited programming experience. Raydiance includes a tangible user interface controlled by a spatial arrangement of physical tokens which are detected using computer vision techniques. Constructing an algorithm is accomplished by creating a directed graph of token connections. Data is processed, then propagated from one token to another by using a novel Light Ray metaphor. Our case study shows how Raydiance can be used to construct a computer vision algorithm for a particular task.
