• Introduction
• Describing Emotion
• Ontologies for Emotion
• Conclusions
• Future Work
• Conceptual Model
• Emotions Ontology
• Use Case
Introduction
• Human beings are eminently emotional• Affective computing: detect and response to
user's emotions• Great variety of theoretical models of
emotions• Emotions are not universal (cultural, language
and individual particularities) Context influence
• Focus (reduce complexity):– Emergent Emotion: states where the person’s whole
system is caught up in the way they react to a particular person or situation
– Just emotion detection and expression systems, not internals of emotion processing in humans
Introduction
• Objectives:– Generic approach to define context-aware
emergent emotions taking different theoretical models into account
– Guide for flexible design of multimodal affective applications with independence of the starting model and the final way of implementation
Describing Emotion
• Most common cognitive models of emotions:– Categorical (Ekman, 1984)– Dimensional (Lang, 1979) – Appraisal (Scherer, 1999)
• Training: recognize user emotional response to some situations
• Then, make user experience more pleasant– If detected sadness
play songs and/or display images associated to a happy user response

• Ontologies for Emotion
• Conclusions
• Future Work
• Conceptual Model
• Emotions Ontology
• Use Case
Conclusions
• Generic model for describing emotions and their detection and expression systems taking contextual and multimodal elements into account– Cognitive interpretation of emotions– Independence from emotion theories
• Formalised as a Web Ontology• Reuse DOLCE and FrameNet
Future Work
• Extending the ontology beyond emergent emotion– Affective states and emotions in social
networks
• Extend emotion-aware application based on Tangible User Interfaces
• Make computers more accessible, personalised and adapted to user needs
