Abstract.We contribute with an extensive field study of a public interactive art installation that applies multimodal interface technologies. The installation is part of a Theater production on Galileo Galilei and includes: projected galaxies that are generated and move according to motion of visitors changing colour depending on their voices; projected stars that configure themselves around shadows of visitors. In the study we employ emotion scales (PANAS), qualitative analysis of questionnaire answers and video-recordings. PANAS rates indicate dominantly positive feelings, further described in the subjective verbalizations as gravitating around interest, ludic pleasure and transport. Through the video analysis, we identified three phases in the interaction with the artwork (circumspection, testing, play) and two pervasive features of these phases (experience sharing and imitation), which were also found in the verbalizations. Both video and verbalisations suggest that visitor's experience and ludic pleasure are rooted in the embodied, performative interaction with the installation, and is negotiated with the other visitors.

The present work considers the training in risk perception carried out with a motorcycle simulator, the Honda Rider Trainer (henceforth HRT), and investigates the effect of the social setting on the trainees’ performance. Through preliminary pilot studies a general procedure and three different social settings are defined: (a) a standard one (one trainee, one instructor); (b) standard with an audience of two schoolmates; and (c) two trainees and one instructor. The results show that in a school environment and with a careful procedure, the users’actions are aligned with the training purpose, and no gender difference emerges in the performance; also, the addition of a small audience, or a parallel training does not modify the trainees’ ability to cope with risks.
