We seek to investigate possibilities of extending the emotional and cognitive experience of using products or services through the cross-modality of vision with other senses (synesthesia). Through multi-sensory, interactive environments, consumers become more engaged in the use of a product or service and may, in fact, participate as co-creators of their own experiences. To achieve the highest level of spontaneity and provoke human activation to enable us to study this, we suggest an experimental context based on interactive technologies, aesthetics and design. For this purpose, we use an artistic environment in the form of an interactive installation. Two examples of such experimental interactive art installations, Art Machine: Mindcatcher and Re-Digital, are described in this paper.
