Abstract
In this paper, we describe details of a design process based on a workshop and the human centered design aiming of creation of new services and products offering unprecedented values. And we explain characteristics of a changing shadow system "Chameleon" produced based on a created concept by the workshop.
Chameleon is a prototype system which realizes the concept of changing shadow as desired. Chameleon consists of a wearable projector and a smart phone, and Chameleon users can enjoy projecting a favorite picture or a movie as user's new shadow on the ground. Moreover, users can play an interaction by layering or connecting projected shadows among users as usage of multi-users.
