Towards Emotional Interaction: Using Movies to Automatically Learn Users' Emotional States

The HCI community is actively seeking novel methodologies to gain insight into the user’s experience during interaction with both the application and the content. We propose an emotional recognition engine capable of automatically recognizing a set of human emotional states using psychophysiological measures of the autonomous nervous system, including galvanic skin response, respiration, and heart rate. A novel pattern recognition system, based on discriminant analysis and support vector machine classifiers is trained using movies’ scenes selected to induce emotions ranging from the positive to the negative valence dimension, including happiness, anger, disgust, sadness, and fear. In this paper we introduce an emotion recognition system and evaluate its accuracy by presenting the results of an experiment conducted with three physiologic sensors.

COORDINSPECTOR: a tool for extracting coordination data from legacy code

More and more current software systems rely on non trivial coordination logic for combining autonomous services typically running on different platforms and often owned by different organizations. Often, however, coordination data is deeply entangled in the code and, therefore, difficult to isolate and analyse separately. COORDINSPECTOR is a software tool which combines slicing and program analysis techniques to isolate all coordination elements from the source code of an existing application. Such a reverse engineering process provides a clear view of the actually invoked services as well as of the orchestration patterns which bind them together. The tool analyses Common Intermediate Language (CIL) code, the native language of Microsoft .Net Framework. Therefore, the scope of application of COORDINSPECTOR is quite large: potentially any piece of code developed in any of the programming languages which compiles to the .Net Framework. The tool generates graphical representations of the coordination layer together and identifies the underlying business process orchestrations, rendering them as Orc specifications

Slicing for architectural analysis

Current software development often relies on non-trivial coordination logic for combining autonomous services, eventually running on different platforms. As a rule, however, such a coordination layer is strongly woven within the application at source code level. Therefore, its precise identification becomes a major methodological (and technical) problem and a challenge to any program understanding or refactoring process. The approach introduced in this paper resorts to slicing techniques to extract coordination data from source code. Such data are captured in a specific dependency graph structure from which a coordination model can be recovered either in the form of an Orc specification or as a collection of code fragments corresponding to the identification of typical coordination patterns in the system. Tool support is also discussed

Extracting and verifying coordination models from source code

Current software development relies increasingly on non-trivial coordination logic for com- bining autonomous services often running on di erent platforms. As a rule, however, in typical non-trivial software systems, such a coordination layer is strongly weaved within the application at source code level. Therefore, its precise identi cation becomes a major methodological (and technical) problem which cannot be overestimated along any program understanding or refactoring process. Open access to source code, as granted in OSS certi cation, provides an opportunity for the devel- opment of methods and technologies to extract, from source code, the relevant coordination information. This paper is a step in this direction, combining a number of program analysis techniques to automatically recover coordination information from legacy code. Such information is then expressed as a model in Orc, a general purpose orchestration language

Art. 114º da Constituição da República Portuguesa: “1. Os partidos políticos participam nos órgãos baseados no sufrágio universal e directo, de acordo com a sua representatividade eleitoral. 2. É reconhecido às minorias o direito de oposição democrática, nos termos da Constituição e da lei. 3. Os partidos políticos representados na Assembleia da República e que não façam parte do Governo gozam, designadamente, do direito de serem informados regular e directamente pelo Governo sobre o andamento dos principais assuntos de interesse público, de igual direito gozando os partidos políticos representados nas Assembleias Legislativas das regiões autónomas e em quaisquer outras assembleias designadas por eleição directa relativamente aos correspondentes executivos de que não façam parte.”. § Article 114 of the Constitution of the Portuguese Republic. "1. Political parties shall participate in organs based on direct and universal suffrage, according to their electoral representation. 2. It is recognized minorities the right to democratic opposition, under the Constitution and the law. 3. Political parties represented in Parliament and not forming part of the Government shall, in particular, the right to be informed regularly and directly by the Government on the progress of the main matters of public interest, equal rights enjoying the political parties represented in Legislative Assemblies of the autonomous regions and any other assemblies formed through direct elections with respect to the corresponding executives who are not part.
