This chapter delves into the dynamic landscape of systems designed for the human centered learning of motor skills, with a primary focus on their application in the context of basketball. As technology continues to advance, opportunities emerge for innovative solutions that enhance skill acquisition, performance analysis, and overall proficiency in...
The relation between affect-driven feedback and engagement on a given task has been largely investigated. This relation can be used to make personalised instructional decisions and/or modify the affect content within the feedback. However, although it is generally assumed that providing encouraging feedback to students should help them adopt a stat...
Recent research has provided solid evidence that emotions strongly affect motivation and engagement, and hence play an important role in learning. In BIG-AFF project, we build on the hypothesis that ``it is possible to provide learners with a personalised support that enriches their learning process and experience by using low intrusive (and low co...
Psychophysiology and behavioral medicine applied to the study of cardiovascular reactivity may contribute to the prevention of cardiovascular diseases such as hypertension. The aim of the study is to evaluate whether a group of trained subjects could face situations of mental stress advantageously with respect to a sedentary group. Two groups of su...
Affect detection is a challenging problem, even more in educational contexts, where emotions are spontaneous and usually subtle. In this paper, we propose a two-stage detection approach based on an initial binary discretization followed by a specific emotion prediction stage. The binary classification method uses several distinct sources of informa...
En este trabajo identificaremos aspectos de diversidad funcional que condicionan la interacción con los sistemas de aprendizaje y resumiremos algunos avances del proyecto MAMIPEC en el tratamiento de los aspectos afectivos. Para ello, comenzaremos repasando los avances realizados en diversos proyectos relacionados. Luego introduciremos cuestiones c...
Hypoxia, defined as decreased availability of oxygen in the body's tissues, can lead to dyspnea, rapid pulse, syncope, visual dys-function, mental disturbances such as delirium or euphoria, and even death. It is considered to be one of the most serious hazards during flight. Thus, early and objective detection of the physiological effects of hypoxi...

Supervising a student's resolution of an arithmetic word prob- lem is a cumbersome task. Dfferent students may use different lines of reasoning to reach the final solution, and the assistance provided should be consistent with the resolution path that the student has in mind. In addition, further learning gains can be achieved if the previous stude...
Supervising a student's resolution of an arithmetic word problem is a cumbersome task. Di�erent students may use di�erent lines of reasoning to reach the nal solution, and the assistance provided should be consistent with the resolution path that the student has in mind. In addition, further learning gains can be achieved if the previous student's...
There exist diverse challenges for inclusive emotions detection in educational scenarios. In order to gain some insight about the difficulties and limitations of them, we have analyzed requirements, accommodations and tasks that need to be adapted for an experiment where people with different functional profiles have taken part. Adaptations took in...
Estamos trabajando para incorporar la valoración de temas afectivos en escenarios de educación inclusivos y personalizados. Para ello partimos de la experiencia obtenida a partir de la realización de proyectos previos, en los que hemos desarrollado un modelado del estudiante y los servicios requeridos para lograr una educación inclusiva y personali...
This work presents some initial ideas on a data mining based approach for building affective collaborative systems. In particular, we focused on the modeling issues involved in providing open affective student interaction models by using data mining techniques. The approach facilitates transferability and analysis without human intervention, and ex...
Collecting and processing data in order to detect and recognize emotions has become a research hot topic in educational scenarios. We have followed a multimodal approach to collect and process data from different sources to support emotion detection and recognition. To illustrate the approach, in this demo, participants will be shown what emotional...
techplay.mobi is a research project aimed at building a platform for developing mobile serious games. The novelty is to support the design of games that consider affective features during the game interaction, provide personalized responses according to users’ interactions, comply with accessibility re-quirements and focus on improving psycho-educa...
Recent progress in affective computing is having an important impact on the development of Intelligent Tutoring Systems (ITS). Many ITS use action logs to record user's interaction with the system, such as to discover important information that help instructional designers to improve the ITS performance. However, finer grain interaction data as wel...
In this paper we introduce the MAMIPEC project. The aim of this project is to explore the application of affective computing to accessible and personalized learning systems. To this end, we consider a user context which includes appliances and devices to enrich user interaction. We describe the research objectives and present on-going work towards...
This paper examines the association of cardiovascular reactivity with thermal thresholds (detection and unpleasantness). Heart period (HP), systolic (SBP) and diastolic (DBP) blood pressure of 42 health young males were recorded during a cardiovascular reactivity task (a videogame based upon Sidman's avoidance paradigm). Thermal sensitivity, assess...
The primary aim of this study was to determine whether font characteristics (serif vs. sans serif) affected performance in a lexical decision task (LDT) under low-contrast conditions. A secondary aim was to explore possible pupilometric effects of the task. Subjects were required to fixate the centre of a computer display after which a word or an o...
Se presentan los resultados de un estudio piloto realizado con nueve pacientes afásicos en el que se lleva a cabo una rehabilitación del lenguaje, impidiendo el uso de otras formas de comunicación, como gestos o señas. El entrenamiento tiene cuatro características principales: las formas lingüísticas son relevantes a las necesidades comunicativas d...
To analyze how pupillary responses reflect mental effort and allocation of processing resources under several load conditions, the pupil diameter of 18 participants was recorded during an auditory digit-span recall task under three load conditions: Low (5 digits), Moderate (8 digits), and Overload (11 digits). In previous research, under all load c...
Durations of eye fixation were recorded for a numerical Stroop effect experiment. Participants (6 men, 19 women; M age=22 yr.) reported the number of characters present in sequences of variable length (2 to 5 characters) while attempting to ignore the identity of the character. Three conditions were included: congruent (the number of characters and...
Smoking is a major public health problem in the European Union. The presentation of health warnings on tobacco packages is a common strategy to alert consumers about the adverse effects of smoking. The main aim of this study was to assess the level of emotional activation and the potential usefulness of the new combined warning labels (both text an...

Using a physiological eye-tracking approach, previous research has suggested that novel health warnings inserted in tobacco ads capture visual attention better than mandated ones. Nonetheless, no up-to-date studies have analyzed the eye movement behavior between smokers and non-smokers to examine the presence of attentional biases towards the warni...
Una respuesta metabólicamente exagerada en personas jóvenes ante situaciones de estrés es considerada como un marcador de riesgo de una futura hipertensión. Asimismo, los autores que investigan las diferencias individuales en la percepción de síntomas consideran que una mayor percepción visceral puede estar asociada con un mejor reconocimiento de s...
The aim of this work was to measure the evolution of heart period and blood pressure during an active coping task and recovery. The following three conditions were compared: two baselines (pre and post) and a task based on Sidman avoidance paradigm, lasting five minutes each. Cardiovascular reactivity was measured by means of heart period and systo...
