The study of emotion in human beings has traditionally been a research interest area in disciplines such as psychology and sociology. The appearance of affective computing paradigm has made it possible to include findings from these disciplines in the development of affective interfaces. Still, there is a lack of applications that take emotion related aspects into account. This situation is mainly due to the great amount of proposed theoretical models and the complexity of human emotions. Besides, the importance that mobile computing area is acquiring has made necessary to bear context related aspects in mind. The proposal presented in this paper is based on a generic ontology for describing emotions and their detection and expression systems taking contextual and multimodal elements into account. The ontology is proposed as a way to develop a formal model that can be easily computerized. Moreover, it is based on a standard, the Web Ontology Language (OWL), which also makes ontologies easily shareable and extensible. Once formalized as an ontology, the knowledge about emotions is used in order to make computers more accessible, personalised and adapted to user needs.

• 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

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
