The approaching of user satisfaction in Digital Media is raising new questions andchallenges in the interactivity relationship between creator and audience. In this workinteractivity is defined as a technology attribute that endows a media environmentwith the capability of reciprocal communication amidst user and technology throughthe technology. What are the key focus extents for managing technology based artproject? What I propose is a new layer of interaction, in which the user is viewed aspart of the interactive installation, being prompted by its pro-active behavior, redefininghim as a creative source. In this dimension, in addition to the language of the artist,what changes is also the perspective of use of the Work of Art: The user is now a livingpart of every creation, contributing to change each time the characteristics. Thanks totechnology, it becomes possible to completely revolutionize the way we conceive anddesign any type of cultural experience and to create spaces for an absolutely innovativeuse. This thesis will engineer the artistic Arduino based installation ArTime inorder to make it into a stable system that can function in museums and exhibitions,experimenting the new layer of interaction with scientific approaches.
