Affective Computing

A suitable design of computer systems is essential to allow information exchange with users. This is especially true nowadays, with the increasing number of systems that we encounter in our everyday environment. These systems need to have sufficient capacity and intelligence to communicate with people in order to allow them to achieve their goals in a suitable, natural and intuitive manner. Thus, it is desirable that the aforementioned systems are able to take into account certain types of information that we are used to perceiving in our human communications. This information is usually transmitted, for example, through speech modulation, body language and facial expressions.

However, systems tend to filter out this type of information. Moreover, some people use devices and interactive systems, such as assistive technology for people with disabilities for communicating with other people. Therefore, it is very important for these people that these devices and systems are able to manage all kinds of information, including the information that is implicitly transmitted, such as facial expressions. Additionally, for a more understandable communication and in order to avoid the message being ambiguous it is necessary to be able to transmit emotions; and speech modulation, facial expressions, body language, etc. are stimuli which are useful as cues or indicators for being able to understand or notice human emotions.

This proposed thesis attempts to support resource developments that need to take emotion transmission into account; both in the communication between users and interactive systems and in the communication between people who use devices as mediators. To this end, the factors to consider with regard to the transmission of affective states have been studied and a model created of the affective context of human-system interactions. An extensible ontology has also been defined, which will also allow the introduction of new information about interactions in a simple manner. Moreover, a global architecture has been created, based on the above-mentioned ontology, in order to guide the development of emotional resources that provide users with more intelligent and natural interfaces. Finally, interactive prototypes have been created to validate the proposed ontology and architecture, and to apply the study to real life cases.
