This paper tracks the development of the author’s work entitled Light Tracer, and examines the surrounding issues of user authorship and creativity within interactivity. Light Tracer is an interactive system which invites the participant to write, draw and trace images in real physical space. The participant is situated in front of a screen reflecting their own image, and by manipulating a series of light sources, marks can be left onscreen such as drawings, messages, traces of physical objects such as faces, hands and bodies. It is the argument of the author that by allowing the user an optimum level of creative authorship within an interactive work, the user can be successfully engaged with the experience of the interaction and in turn produce and create themselves.
