An Emotional Agent for Moral Impairment Rehabilitation in TBI Patients
The ability to identify the emotions of others is a key component of what is known as social cognition. Narratives exploit this mechanism to create an emotional bond with the characters and to maintain the engagement of the audience throughout the story. In this paper, we illustrate a case study in emotion understanding in stories that exploits a computational agent to explore emotion impairment in a group of traumatic brain injured people. The study focuses on moral emotions, aiming to investigate the differences in moral functioning that characterize traumatic brain injured patients. After comparing the understanding of the moral and emotional facets of the agent's behavior in traumatic brain injured patients and in neurologically intact controls, slight–yet meaningful–differences were observed between the two groups. We describe the test methodology and results, highlighting their implications for the design of rehabilitation applications based on virtual agents
Memories for Life: A Review of the Science and Technology
This paper discusses scientific, social and technological aspects of memory. Recent developments in our understanding of memory processes and mechanisms, and their digital implementation, have placed the encoding, storage, management and retrieval of information at the forefront of several fields of research. At the same time, the divisions between the biological, physical and the digital worlds seem to be dissolving. Hence opportunities for interdisciplinary research into memory are being created, between the life sciences, social sciences and physical sciences. Such research may benefit from immediate application into information management technology as a testbed. The paper describes one initiative, Memories for Life, as a potential common problem space for the various interested disciplines
Towards simulated morality systems: Role-playing games as artificial societies
Computer role-playing games (RPGs) often include a simulated morality system as a core design element. Games' morality systems can include both god's eye view aspects, in which certain actions are inherently judged by the simulated world to be good or evil, as well as social simulations, in which non-player characters (NPCs) react to judgments of the player's and each others' activities. Games with a larger amount of social simulation have clear affinities to multi-agent systems (MAS) research on artificial societies. They differ in a number of key respects, however, due to a mixture of pragmatic game-design considerations and their typically strong embeddedness in narrative arcs, resulting in many important aspects of moral systems being represented using explicitly scripted scenarios rather than through agent-based simulations. In this position paper, we argue that these similarities and differences make RPGs a promising challenge domain for MAS research, highlighting features such as moral dilemmas situated in more organic settings than seen in game-theoretic models of social dilemmas, and heterogeneous representations of morality that use both moral calculus systems and social simulation. We illustrate some possible approaches using a case study of the morality systems in the game The Elder Scrolls IV: Oblivion
On the Relationship between People, Objects, & Interactive Technologies: Transforming Digital & Physical experiences through the process of Realizing Empathy
La manera com les persones es relacionen amb el seu entorn, ja sigui físic o digital, és cada cop més complexa i fugaç, fent que la relació de l'usuari amb els seus objectes i eines digitals, de vegades, sigui extrema i de curta durada. Tanmateix, la propietat d'objectes i objectes tecnològics interactius no és buida de significat, són mostres de reflexió i representació per als altres i del seu paper a la societat. La clau per mantenir una relació i el significat amb aquests objectes rau en el disseny i la intenció de l'experiència interactiva creada. Inspirats en les disciplines de la psicologia, el procés de disseny, la interacció humà-ordinador i els models de negoci, aquesta tesi explora, analitza, crea i prova els fonaments teòrics sobre l'empatia i el concepte d'entaular una relació de llarga durada entre les persones i les tecnologies interactives.
Amb aquesta finalitat, aquesta tesi es divideix en 4 fases: (1) l’estudi en profunditat de les referències bibliogràfiques dins del sector HCI, amb especial atenció al rol del disseny i la psicologia amb la intenció de respondre preguntes com: “Com podem construir relacions de llarga durada entre persones i objectes intel·ligents?” (2) Recopilar i adoptar definicions, eines i terminologia de treballs relacionats que aportin a la construcció de la contribució principal d'aquesta tesi, (3) Crear i presentar un model d'interacció entre persones i tecnologia que aporti a una interacció de llarga durada, i (4) presentar un cas d’estudi on s’implementi el model proposat.
Després del treball bibliogràfic, al sector de l'HCI, s'ha identificat un buit, fruit de les principals preocupacions expressades: la manca de connexió entre la teoria i la pràctica del disseny, així com una mancança en l’àmbit de l'Empatia. El resultat fa que molts dels models d’interacció amb intenció empàtica i afectiva no se sustentin entre si. Això ens ha portat a la segona fase de la tesi on aprofitem les referències de múltiples disciplines per estudiar què és l'empatia, com s'implementa, com es percep i com evoluciona cap a l'objectiu d'una relació a llarg termini, com a punt focal cap a les principals contribucions de la tesi. .
Després de reunir i analitzar exhaustivament les referències al voltant de l'empatia, entrem a la tercera fase on presentem el model teòric d'interacció amb el potencial d'establir una interacció a llarg termini i l’anomenat Procés de realització de l'empatia (RE). Més que intentar definir què és l'empatia, aquesta proposta intenta oferir una perspectiva diferent de l'empatia i visualitza el seu abast com un procés influenciat per models de diàleg i col·laboració amb el propòsit de crear comprensió mútua i donar significat a aquest intercanvi.
Amb un model clar i una sòlida base teòrica, la fase final de la tesi cerca provar el model proposat amb l'objectiu d'observar si es poden detectar indicadors d'afecció afectiva i confiança entre una persona i el seu objecte tecnològic. En aquest cas, vam tenir l'oportunitat de treballar amb robots socials com el nostre “altre actor” per dissenyar les proves del model. Aquestes proves pretenien capturar els indicadors d'empatia entre un humà i un robot que abraça: l'aferrament afectiu, la confiança, la regulació de les expectatives i la reflexió sobre la perspectiva de l'altre dins un conjunt d'estratègies de col·laboració. Plantegem la hipòtesi que una estratègia de col·laboració activa condueix a un compromís més significatiu de generar empatia entre un humà i un robot en comparació amb una estratègia passiva. Els resultats són encoratjadors i clarament estableixen un camí per a futures investigacions sobre el disseny d'aquest model. La forma en que las personas se relacionan con su entorno, ya sea físico o digital, se vuelve cada vez más compleja y fugaz, haciendo que la relación del usuario con sus objetos y herramientas digitales, en ocasiones, sea extrema y de corta duración. Sin embargo, la propiedad de objetos y objetos tecnológicos interactivos no es vacía de significado, son muestras de reflexión y representación para los demás y de su papel en la sociedad. La clave para mantener una relación y significado con estos objetos radica en el diseño y la intención de la experiencia interactiva creada. Inspirados en las disciplinas de la psicología, el proceso de diseño, la interacción humano-ordenador y los modelos de negocio, esta tesis explora, analiza, crea y prueba los fundamentos teóricos sobre la empatía y el concepto de entablar una relación de larga duración entre las personas y las tecnologías interactivas.
Con este fin, esta tesis se divide en 4 fases: (1) estudio en profundidad de las referencias bibliográficas dentro del sector HCI, con especial atención al rol del diseño y la psicología con la intención de responder a preguntas como: “¿Cómo podemos construir relaciones de larga duración entre personas y objetos inteligentes?”(2) Recopilar y adoptar definiciones, herramientas y terminología de trabajos relacionados que aporten a la construcción de la contribución principal de esta tesis, (3) Crear y presentar un modelo de interacción entre personas y tecnología que aporte a una interacción de larga duración, y (4) presentar un caso de estudio donde se implemente el modelo propuesto.
Tras el trabajo bibliográfico en el sector del HCI se ha identificado un vacío, fruto de las principales preocupaciones expresadas: la falta de conexión entre la teoría y la práctica del diseño, así como una falta en el tema de la Empatía. El resultado hace que muchos de los modelos de interacción con intención empática y afectiva no se sustenten entre sí. Esto nos ha llevado a la segunda fase de la tesis en la que aprovechamos las referencias de múltiples disciplinas para estudiar qué es la empatía, cómo se implementa, cómo se percibe y cómo evoluciona hacia el objetivo de una relación a largo plazo, como punto focal hacia las principales contribuciones de la tesis. .
Después de una reunir y analizar exhaustivamente las referencias en torno a la empatía, entramos en la tercera fase donde presentamos el modelo teórico de interacción con el potencial de entablar una interacción a largo plazo y denominado Proceso de realización de la empatía (RE). Más que intentar definir qué es la empatía, esta propuesta trata de ofrecer una perspectiva diferente a la empatía y visualiza su alcance como un proceso influenciado por modelos de diálogo y colaboración con el propósito de crear comprensión mutua y dar significado a ese intercambio.
Con un modelo claro y una sólida base teórica, la fase final de la tesis busca probar el modelo propuesto con el objetivo de observar si el modelo puede detectar indicadores de Apego Afectivo y Confianza entre una persona y su objeto tecnológico. En el caso de este trabajo, tuvimos la oportunidad de trabajar con robots sociales como nuestro “otro actor” para diseñar las pruebas del modelo. Estas pruebas pretendían capturar los indicadores de de empatía entre un humano y un robot que abarca: el apego afectivo, la confianza, la regulación de las expectativas y la reflexión sobre la perspectiva del otro dentro de un conjunto de estrategias de colaboración. Planteamos la hipótesis de que una estrategia de colaboración activa conduce a un compromiso más significativo de generar empatía entre un humano y un robot en comparación con una estrategia pasiva. Los resultados son alentadores y claramente establecen un camino para futuras investigaciones sobre el diseño de este modelo. How people engage with their surroundings, whether physical or digital, becomes increasingly complex and rapid, making the user’s relationship with their objects and digital tools, at times, extreme and short-lived. Yet, there is still meaning in ownership of objects and interactive technological objects, they are tokens of reflection and representation to others and their role in society. The key to sustaining a relationship and sense of meaning with these objects lies in the design and intention of the interactive experience created. Inspired by disciplines of psychology, design, Human-computer interaction, and business modeling, this thesis explored, analyzed, created, and tested theoretical foundations on Empathy and the concept of initiating a long-term relationship between people and their interactive technologies.
To that end, the thesis book was managed in 4 main stages: (1) presenting a deeper dive into bibliographic references within HCI and the role of both design and psychology in the attempt to tackle questions like: “How can we build long-term relationships between people and their smart objects?” (2) Collect and adopt from related works that helped build the main contributions of the thesis book, (3) Create an interaction model between humans and their technology that lent itself for potential long-term engagement, and (4) a case study that implemented and instantiated the model designed.
After mapping the HCI bibliographical works in the first phase, a gap was revealed indicative of the main concerns expressed: a lack of connection between theory and design practice as well as a lack in the topic of Empathy. The result makes many of the models of interaction with empathetic and affective intention unsupported between each other. This has led us to the second phase of the thesis where we leveraged references across multiple disciplines to survey what empathy is, how it is implemented, perceived and evolved toward the goal of long-term relationship, as a focal point toward the main thesis contributions.
After an exhaustive gathering and analysis of the work around Empathy, we entered the third phase where we present the proposed theoretical model of interaction with the potential for long-term engagement named the Process of Realizing Empathy (RE). Rather than attempting to further define empathy, this proposal is about offering a different perspective to empathy that visualizes its scope as a process influenced by dialogue and collaborative models with the goal to reach meaning between the actors involved.
With a clear model in place and a strong theoretical foundation, the final phase of the thesis looked to test the proposed model with the goal of observing if the model can provoke its indicators of Affective Attachment and Trust between a person and their technological object. In the case of this thesis work, we had the opportunity to work with social robots as our “other actor” to design the tests for the model. This testbed meant to capture the indicators of early empathy realization between a human and a robot encompassing affective attachment, trust, expectation regulation, and reflecting on the other’s perspective within a set of collaborative strategies. We hypothesized that an active collaboration strategy is conducive to a more meaningful and purposeful engagement of realizing empathy between a human and a robot compared to a passive one. The results are encouraging and clearly establish a path for further research on this model’s design.
Reports of the AAAI 2019 spring symposium series
Applications of machine learning combined with AI algorithms have propelled unprecedented economic disruptions across diverse fields in industry, military, medicine, finance, and others. With the forecast for even larger impacts, the present economic impact of machine learning is estimated in the trillions of dollars. But as autonomous machines become ubiquitous, recent problems have surfaced. Early on, and again in 2018, Judea Pearl warned AI scientists they must "build machines that make sense of what goes on in their environment," a warning still unheeded that may impede future development. For example, self-driving vehicles often rely on sparse data; self-driving cars have already been involved in fatalities, including a pedestrian; and yet machine learning is unable to explain the contexts within which it operates
Design methodology for 360-degree immersive video applications
360-degree immersive video applications for Head Mounted Display (HMD) devices offer great potential in providing engaging forms of experiential media solutions. Design challenges emerge though by this new kind of immersive media due to the 2D form of resources used for their construction, the lack of depth, the limited interaction, and the need to address the sense of presence. In addition, the use of Virtual Reality (VR) is related to cybersickness effects imposing further implications in moderate motion design tasks.
This research project provides a systematic methodological approach in addressing those challenges and implications in 360-degree immersive video applications design. By studying and analysing methods and techniques efficiently used in the area of VR and Games design, a rigorous methodological design process is proposed. This process is introduced by the specification of the iVID (Immersive Video Interaction Design) framework.
The efficiency of the iVID framework and the design methods and techniques it proposes is evaluated through two phases of user studies. Two different 360-degree immersive video prototypes have been created to serve the studies purposes. The analysis of the purposes of the studies ed to the definition of a set of design guidelines to be followed along with the iVID framework for designing 360-degree video-based experiences that are engaging and immersive
A Description Logic Framework for Commonsense Conceptual Combination Integrating Typicality, Probabilities and Cognitive Heuristics
We propose a nonmonotonic Description Logic of typicality able to account for
the phenomenon of concept combination of prototypical concepts. The proposed
logic relies on the logic of typicality ALC TR, whose semantics is based on the
notion of rational closure, as well as on the distributed semantics of
probabilistic Description Logics, and is equipped with a cognitive heuristic
used by humans for concept composition. We first extend the logic of typicality
ALC TR by typicality inclusions whose intuitive meaning is that "there is
probability p about the fact that typical Cs are Ds". As in the distributed
semantics, we define different scenarios containing only some typicality
inclusions, each one having a suitable probability. We then focus on those
scenarios whose probabilities belong to a given and fixed range, and we exploit
such scenarios in order to ascribe typical properties to a concept C obtained
as the combination of two prototypical concepts. We also show that reasoning in
the proposed Description Logic is EXPTIME-complete as for the underlying ALC.Comment: 39 pages, 3 figure
