14 May 20th 2009D. Bernini, PhD research status14 Area: Interactive-Art Systems Interactive-Art – “a general classification of any type of art mainly interactive, where the viewer turns out to be an active player dialoguing with the artifact, possibly changing it” (Marcos et al 2009) – “the attempt is to try to make communication between the work of art and the observer a sustained two-way experience” (Burnham 1968) – Origins: Dada Movement, Performance Art, Kinetic Art Interactive-Art systems – Interactive artworks as interactive systems – Importance of understanding artworks in their environmental context (Edmonds et al 2004) – All things “which processes art data,…are components of the work of art” (Burnham 1968) – Origins: Jack Burhnam, Roy Ascott

15 May 20th 2009D. Bernini, PhD research status15 My focus: ICT-supported interactive art-systems Artworks or installations where some interactions are achieved by ICT – For itself: the interactions are integrant part of the artwork/installation – For the exhibition: valorization of traditional artworks/installations Museums and galleries (Iamascope, see Fels 1997) ( Studio Azzurro installations (Utterback’s works

16 May 20th 2009D. Bernini, PhD research status16 Needs and whishes (1) Tools to design ICT-supported interactive art-systems more oriented to the artist perspective – Different visual programming tools..…but too specific E.g. MAX/MSP: audio/video processing Technology oriented – From (Edmonds 2004): “We need computing resources and software to enable the kind of guided or playful exploration of possibilities in which artists engage” “One solution might be the creation of more software tools that allow the artist access to deeper levels of the computer’s programming system, rather than software applications that have been developed for specific tasks such as image manipulation.” “Such tools could provide a bridge between the use of an environment that requires programming knowledge and the ‘closed’ application, which does not provide sufficient flexibility.”

17 May 20th 2009D. Bernini, PhD research status17 Needs and whishes (2) Suitable software abstractions – From (Edmonds et al 2005) “Major aesthetic decisions may be embodied in fairly deep programming decisions and they need to be open for full debate in the team. This seems to come down to finding representations of the code that can be used to facilitate such debates ” They should acts as shared languages/representations, they have to enable multiple points of views and to facilitate the discussion

18 May 20th 2009D. Bernini, PhD research status18 Key intrinsic aspects Real-time – The interactive artwork may require interactions with strong time constraints Multi-modal – Multiple input sources and output effects E.g. input: sensors and devices for movement, sound recognition E.g. output: actuators and devices for audio-video generation, light control – “the integration potential of digital technology is vital to innovative creative systems.” (Edmonds et al 2005)

19 May 20th 2009D. Bernini, PhD research status19 A possible answer A model for interactive art-systems – Two views “Conceptual view”: metaphors which meet artist needs – How artists would like to conceive the interactivity, the audience participation, independently from available technologies? “Concrete view”: an effective reification of the metaphors in terms of software elements which enable the fulfillment of the intrinsic system requirements – Beyond ad-hoc approaches – It must allow the reification of the conceptual view in an effective, robust, scalable way real-time and multimodal requirements

20 May 20th 2009D. Bernini, PhD research status20 “Architectures for Interactive-Art Systems” Bottom-up path First (thesis’ core): studying effective software architectures for these systems – Goal: to abstract from the specific technologies (sensors, actuators and other devices) – Reuse/rethink/enhance my experience on critical systems.. – plus Interaction Design/Human-Computer Interaction approaches – Results applicable to various class of systems E.g. Video-surveillance systems Second: identifying some artist metaphors to conceive interactive-art systems – From collaborations with artists/studios – Interactive artworks as composition of…?
