This workshop paper was submitted and accepted for the workshop "approaches towards movement-based interaction" at the Aarhus 2005 critical computing conferrence. Movement and Space – Exploring the Space in Movement based Interaction discusses the use of movements as inputs in a number of projects that the authors have been involved in. The paper is written by Thomas Riisgaard Hansen, Eva Eriksson and I. Abstract In this paper we explore the space in which movement based interaction takes place. We have in several projects explored how fixed and mobile cameras can be used in movement based interaction and will shortly describe these projects. Based on our experience with working with movement-based interaction we will briefly introduce and discuss how learning, mapping and multi-user interaction are important when designing movement based interaction. read the entire paper in pdf here
