“Integrated System for Emergency” project

• Studying and experimenting innovative methodologies and tools for the realization of integrated systems for the prevention and management of emergencies– InSyEme, FIRB, Italian Ministry of Research – October 2007-October 2010– http://www.unifi.it/insyeme

• Four work packages (WP), various italian universities• WP1 - “Reference scenario”, Leader: Prof. M. Listanti, University of

Roma-La Sapienza• WP2 - “Communication Infrastructure”, Leader: Prof. R. Fantacci,

University of Firenze• WP3 - “Mobile Grid”, Leader: Prof. M. Vanneschi, University of Pisa• WP4 - “Domain Abstractions”, Leader: Prof. F. Tisato, University of

Milano-Bicocca


InSyEme & my goals

• Goal 1: distribution & execution of specific forecasting models– E.g. models for flood forecasting on fireman’s PDA

• Goal 2: dynamic reconfiguration of InSyEme applications– Reconfigure the application without completely stop it

• To enable adaptivity w.r.t resource availability, network connectivity, power saving and so on

– Reconfiguration: change• some elements of the application• the allocation among elements and computational nodes

Approaches & studies

• Software Engineering– (Ghezzi et al 2004), (Heineman and Council 2001)

• Software Architecture– (Shaw-Garlan, 1996), (Mellor et al 2004)

• Dynamic system reconfiguration– (Hillman-Warren, 2004), (Oreizy et al 2008)

• Architectures for dynamical reconfigurable systems– (Cazzola et al, 1998), (Caflisch et al., 2005)


InSyEme & my results• Preliminary definition of a specific design approach

– Inspired by Model Driven Architecture & proposed by Prof. F. Tisato

– oriented to the information flows, user-oriented perspective

• Two distinguished but related software architectures – Base-architecture: “Component & connector” architecture– Meta-architecture: observes & controls the Base-architecture

• Preliminary definition in (Bernini 2008)

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


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 installationswww.studioazzurro.com)

(Utterback’s workshttp://www.camilleutterback.com)


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.”


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


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)


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


“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…?


PhD courses

• Fundamental: collaborations/interactions with some artist/centre/lab– Interactive art projects– Technological possibilities & case studies– Studio Azzurro? (DeMichelis)

• PhD formation– PhD course to this aim– Courses on art & technology, art & design..

• Domus Academy?• Course of some Fine Arts Academy?

– Abroad period on a specific centre/lab?• Ars Electronica• Berlin centers• etc
