So, why does a project like CALLAS exist? Because in today’s digital society, natural communication between people, based on gestures, movements, sounds and verbal expressions is imposed with a much greater emphasis on a new form of interaction, that being between people and machines. It is emotion, in all expressions, that has a fundamental role in the conditioning of natural communication between two people that must be emulated when service based interfaces are developed to enhance the interaction between people and machines. For this reason, the affective interfaces developed by CALLAS cover a fundamental role in the new media experiences like: Digital Theatre, Interactive TV, Augmented Reality Art and Interactive Public Performances.
Emotional multimodal interfaces aim at achieving the highest level of naturalness in human-computer interaction. One of the main challenges for CALLAS is to implement the concept of affective emotional input for interactive media rather than within a traditional interface paradigm. Affective and emotional interfaces are generally concerned with the real-time identification of user emotions to determine system response. They rely most often on emotions such as joy, fear or anger. However, interaction with new media such as interactive narratives, digital theatre or digital arts involves different ranges of emotions on the user’s side, some of which correspond to responses to aesthetic properties of the media, or characterise the user experience itself in terms of enjoyment and entertainment. To identify these, more complex articulations of modalities are required. Such key aspects are currently being investigated within the CALLAS project in the specific area of Art and Entertainment applications.
CALLAS wants to demonstrate the real use of the multimodal affective interfaces across the implementation of concrete applications. These can improve a performance in the digital Theatre and also the recognition of the emotional states of actors on –stage, creating a virtual scenography. This is one of the application schemes that its launching from the creations in Digital Theatre of Studio Azzurro Produzioni, a cutting edge lab in New Media Arts, who are one of the partners of the project. At the same time, the affective multimodal interfaces can also contribute to the future development of art forms like interactive TV or other types of digital art based on the emotional-cognitive experience of the audience.
Some of the principal partners of the 19 organisations that make up the CALLAS consortium are the media giant BBC, a number of European Universities, and a variety of small and medium enterprises, including Metaware S.p.A of Pisa, Italy. They are currently developing the software framework and they are also the director of communications for the project. The project co-ordinator is Engineering Ingegneria Informatica, Research and Development Department.
