Architecture for Collaborative Learning Activities in Hybrid Learning Environments

3D virtual worlds are recognized as collaborative learning environments. However, the underlying technology is not sufficiently mature and the virtual worlds look cartoonish, unlinked to reality. Thus, it is important to enrich them with elements from the real world to enhance student engagement in learning activities. Our approach is to build learning environments where participants can either be in the real world or in its mirror world while sharing the same hybrid space in a collaborative learning experience. This paper focuses on the system architecture and a usability study of a proof-of-concept for these hybrid learning environments. The architecture allows the integration of the real world and its 3D virtual mirror; the exchange and geolocalization of multimodal information, and also the orchestration of learning activities. The results of the usability evaluation show positive engagement effects on participants in the mirror world and, to a lesser extent, on those in the real world.This research has been partially supported by the following projects: “España Virtual” within the Ingenio 2010 program, subcontracted by Elecnor Deimos, "EEE" (TIN2011-28308-C03-01) funded by the Spanish National Plan of Research, Development and Innovation, and "eMadrid", S2009/TIC-1650 “Investigación y Desarrollo de tecnologías para el e-learning en la Comunidad de Madrid” funded by the Region of Madrid.Publicad

Imaginative play with blended reality characters

Thesis (S.M.)--Massachusetts Institute of Technology, School of Architecture and Planning, Program in Media Arts and Sciences, 2011.Cataloged from PDF version of thesis.Includes bibliographical references (p. 132-137).The idea and formative design of a blended reality character, a new class of character able to maintain visual and kinetic continuity between the fully physical and fully virtual; the technical underpinnings of its unique blended physical and digital play context and the evaluation of its impact on children's play are the contents of this thesis. A play test study with thirty-four children aged three and a half to seven was conducted using non-reactive, unobtrusive observational methods and a validated evaluation instrument. Our claim is that young children have accepted the idea, persistence and continuity of blended reality characters. Furthermore, we found that children are more deeply engaged with blended reality characters and are more fully immersed in blended reality play as co-protagonists in the experience, in comparison to interactions with strictly screen-based representations. As substantiated through the use of quantitative and qualitative analysis of drawings and verbal utterances, the study showed that young children produce longer, detailed and more imaginative descriptions of their experiences following blended reality play. The desire to continue engaging in blended reality play as expressed by children's verbal requests to revisit and extend their play time with the character positively affirms the potential for the development of an informal learning platform with sustained appeal to young children.by David Yann Robert.S.M

Design for Child-Robot Play The implications of Design Research within the field of Human-Robot Interaction studies for Children

This thesis investigates the intersections of three disciplines, that are Design Research, Human-Robot Interaction studies, and Child Studies. In particular, this doctoral research is focused on two research questions, namely, what is (or might be) the role of design research in HRI? And, how to design acceptable and desirable child-robot play applications? The first chapter introduces an overview of the mutual interest between robotics and design that is at the basis of the research. On the one hand, the interest of design toward robotics is documented through some exemplary projects from artists and designers that speculate on the human-robot coexistence condition. Vice versa, the robotics interest toward design is documented by referring to some tracks of robotic conferences, scienti c workshops and robotics journals which focused on the design-robotics relationship. Finally, a brief description of the background conditions that characterized this doctoral research are introduced, such as the fact of being a research founded by a company. The second chapter provides an overview of the state of the art of the intersections between three multidisciplinary disciplines. First, a de nition of Design Research is provided, together with its main trends and open issues. Then, the review focuses on the contribution of Design Research to the HRI eld, which can be summed up in actions focused on three aspects: artefacts, stakeholders, and contexts. This is followed by a focus on the role of Design Research within the context of children studies, in which it is possible to identify two main design-child relationships: design as a method for developing children’s learning experiences; and children as part of the design process for developing novel interactive systems. The third chapter introduces the Research through Design (RtD) approach and its relevance in conducting design research in HRI. The proposed methodology, based on this approach, is particularly characterized by the presence of design explorations as study methods. These, in turn, are developed through a common project’s methodology, also reported in this chapter. The fourth chapter is dedicated to the analysis of the scenario in which the child-robot interaction takes place. This was aimed at understanding what is edutainment robotics for children, its common features, how it relates to existing children play types, and where the interaction takes place. The chapter provides also a focus on the relationship between children and technology on a more general level, through which two themes and relative design opportunities were identi ed: physically active play and objects-to-think-with. These were respectively addressed in the two design explorations presented in this thesis: Phygital Play and Shybo. The Phygital Play project consists of an exploration of natural interaction modalities with robots, through mixed-reality, for fostering children’s active behaviours. To this end, a game platform was developed for allowing children to play with or against a robot, through body movement. Shybo, instead, is a low-anthropomorphic robot for playful learning activities with children that can be carried out in educational contexts. The robot, which reacts to properties of the physical environment, is designed to support different kinds of experiences. Then, the chapter eight is dedicated to the research outcomes, that were de ned through a process of reflection. The contribution of the research was analysed and documented by focusing on three main levels, namely: artefact, knowledge and theory. The artefact level corresponds to the situated implementations developed through the projects. The knowledge level consists of a set of actionable principles, emerged from the results and lessons learned from the projects. At the theory level, a theoretical framework was proposed with the aim of informing the future design of child- robot play applications.

Friend Me Your Ears: A Musical Approach to Human-Robot Relationships.

PhDA relationship is something that is necessarily built up over time, however, Human-Robot Interaction (HRI) trials are rarely extended beyond a single ses- sion. These studies are insufficient for examining multi-interaction scenarios, which will become commonplace if the robot is situated in a workplace or adopts a role that is part of a human's routine. Long term studies that have been exe- cuted often demonstrate a declining novelty effect. Music, however, provides an opportunity for affective engagement, shared creativity, and social activity. This being said, it is unlikely that a robot best equipped to build sustainable and meaningful relationships with humans will be one that can solely play music. In their day-to-day lives, most humans encounter machines and computer programs capable of executing impressively complex tasks to a high standard that may provide them with hours of engagement. In order to have anything that that could be classed as a social relationship, the human must have the sense that their interactions are taking place with another, a phenomenon known as social presence. In this thesis, we examine whether the addition of simulated social behaviours will improve a sense of believability or social presence, which, along with an engaging musical interaction, will allow us to move towards something that could be called a human-robot relationship. First, we conducted a large online survey to gain insight into relationships based in regular music activ- ity. Using these results, we designed, constructed and programmed Mortimer, a robotic system capable of playing the drums and a responsive composition algorithm to best meet these aims. This robot was then used in a series of studies, one single session and two long-term, testing various simulated social behaviours to compliment the musical improvisation. These experiments and their results address the paucity of long-term studies both speci cally in Social Robotics and in the broader HRI eld, and provide a promising insight into a possible solution to generally poor outcomes in this area. This conclusion is based upon the model of a positive human-robot relationship and the method- ological approach of automated behavioural metrics to evaluate robotic systems in this regard developed and detailed within the thesis.the EPSRC as part of the Media and Arts Tech-nology Doctoral Training Centre, EP/G03723X/2
