The component renders the user’s emotive state by real-time generation of an affectivisation of music. Some key characteristics of the music are altered in response to the changing mood of the user psychologically correlated and expressed in the PAD model. Processing is done in real-time with a view to suit the composed music to user’s emotive state or affect. The focus is on music synthesis and affectivisation in a minimalist context, without direct user input but rather an implicit emotive input, derived from a PAD dimensional model that drives the synthesis and affectivisation process.

Besides functional tests, extensive experimentation of Affective Music Synthesis component in CALLAS is done in Proof-of-Concepts applications for edutainment:

• the Musickiosk,  where  the Affective Music Synthesis component is used to indicate which of the there different rooms in the kiosk, with varied instrumentation – strings, wind instruments and percussion, is active at a given point in time, so that relevant instrumentation is employed in the music synthesis process.

Additional reference to the component usage is made in CALLAS Newsletter2 and in the following CALLAS paper:
