InSyEme & my goals
• Goal 1: distribution & execution of specific forecasting
models
– E.g. models for flood forecasting on fireman’s PDA
Local Parameters
e.g. a=3 b=4
i-th river section
Local Flood Out
Forecast
e.g. y=6
Local
Model
e.g. y=ax+b
In
Past Local
Flood Levels
e.g. x=3,x=4,…
i-th river section
• 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

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)

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.”

16
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…?
