Designing Modular Robotic Playware

In this paper, we explore the design of modular robotic objects that may enhance playful experiences. The approach builds upon the development of modular robotics to create a kind of playware, which is flexible in both set-up and activity building for the end-user to allow easy creation of games. Key features of this design approach are modularity, flexibility, and construction, immediate feedback to stimulate engagement, activity design by end-users, and creative exploration of play activities. These features permit the use of such modular playware by a vast array of users, including disabled children who often could be prevented from using and taking benefits from modern technologies. The objective is to get any children moving, exchanging, experimenting and having fun, regardless of their cognitive or physical ability levels. The paper describes two prototype systems developed as modular robotic tiles, and discusses the challenges and opportunities of this modular playware when used by children with different cognitive abilities

Evaluación de aplicaciones educativas de AR con estudiantes adultos

There is a growing interest in the educational applications of Augmented Reality (AR). While most applications of these technologies have been examined in the context of children education, our knowledge about their usefulness in adult education is deficient and particularly more in the category of Location-Based Augmented Reality (LBMAR) games, so the aim of this thesis is to examine the opinions of adult learners (young, middle-aged and elderly) about one particular LBMAR game, the “Ingress”. The main problems addressed by this research comprise questions relating to the usefulness of some key technological components of AR in education (secondarily) and to aspects of training adults by using AR (primarily). As concerns the technological aspects, i.e. "which one of the three types of AR (marker-based, markerless, location-based) is more often associated with naturalistic approaches and what are their relative advantages?”, this research showed that naturalistic approaches applied to marker-based AR enhance active participation in virtual environments, motivate learners, promote personal involvement in conquering new information, offer different perspectives of the content and arouse interest for knowledge. In the case of markerless AR, naturalistic designs foster participants’ collaboration in games, enhance interactivity, offer panoramic views, visualization, and the possibility to examine the role of visual controls. Moreover, naturalistic approaches applied to location-based AR are suitable for designing multidisciplinary applications, can be used for training and have the possibility to be designed so as to account for locality and context. The fact that, as appears from the peer-reviewed literature that was examined, the location-based AR technologies are more appropriate for education and for smartphones, hints that a deeper examination of their potential usefulness for education (and for adult education in particular) might be interesting. As concerns the educational aspects, which also constitute the main focus of the thesis, these focus on the exploration of the usefulness of the LBMAR game “Ingress” in adult education, by answering two intertwined questions: a) how to assess opinions of adult learners about the LBMAR game “Ingress”? and b) what do adult learners think about this game and how do they perceive its features? Providing answers to these questions is tantamount to receiving adequate results from quantitative and qualitative empirical research which would be designed so as to explore their opinions, views and attitudes with respect to this LBMAR game. Hence, 45 adult persons from Greece, aged 20 to 62,cooperated as subjects of this research. They followed a short introductory informal training (on AR, VR, MAR and the games that are relevant to these technologies) by the researcher of this thesis and were subsequently given the instructions of how to use “Ingress” on a smartphone. The quantitative research was carried out before and after training and all trainees participated by filling 31 Likert-type closed questions before and after training. The qualitative research was based on the analysis of their responses to two different sets of open-ended questions. The first set consisted in 5 such questions to which answered 24 participants and the second set had 2 broader questions to which responded 36 participants. This research showed the advantages for adult education of integrating the ARCS model into the learning phase of an LBMAR game. Specifically, it was shown that using Keller’s widely known “ARCS model” (Attention – Relevance – Confidence - Satisfaction) enabled the classification of users’ responses with respect to their interaction with the game and is therefore useful in evaluating adult education with LBMAR games. The players’ responses did not change linearly with their age and the training has had different impact on each age group of learners. Also, statistical analyses proved that training increased the scores of the factors of ARCS model. Other results of this research showed that those over 36 years old focused more on the facts that the play of “Ingress” is primarily a geographical game and its scenario reflects interesting discussions about the evolution of humanity. Participants in the age groups 20–35 and >52 agreed that the game does not have idle phases, that it combines excitement with insecurity, and that it is pleasant to play locally a game of planetary proportions.Another age-related observation concerned the answers to the question (“How do you feel when you endow the geographical space with personal preferences?”) between age groups with age groups agreeing in pairs: the first two age groups (20–30) and (30–40) agreed more than with the last two (40–50) and (50–60). Yet, in question “Do you think that the game offers opportunities for learning and teaching geography, building on your previous geographical knowledge?” , there was an overlap in the responses of participants among age groups. As for the first question, the most critical concept was: “the users feel a kind of nostalgia”, followed by the concept “the users consider portals as personal creations”. In the case of the second question, the most critical concept was that the participants believe that the game offers entirely new opportunities for education in geography, compared with their previous experiences. This fosters an evidence of constructivist approaches to adult education and, also, relevance of some other prominent theories of adult education such as humanism. Methodologically, this research it was shown that content analysis is a valuable method for exploring opinions and attitudes of adult users towards MAR games and Jaccard indices can be used to quantitatively explore themes emerging from content analysis. Content analysis was performed on the users’ responses qualitatively in order to identify characteristic sentences expressing attitudes and opinions. For the quantitative assessment of similarities between responses for each question and subconcept, the Jaccard similarity index was calculated pair-wise for every pair of participants. In addition to the Jaccard indices and furthering the scope of new methods for content analysis, this thesis shows how to use Social Network Analysis (SNA) to model concept maps, thus opening up excellent opportunities to create visualizations of concepts and their inter-relationships. Quantitative aspects of SNA analysis (i.e. by using radial centrality and information centrality) provide mechanisms suitable to measure internal relationships in concept maps (in addition to visual inspection) that would not otherwise be visible. Using SNA enabled the classification of users’ responses with respect to their interaction with the game and therefore was a fruitful approach for education that involves MAR games. Furthermore, with this novelty, it is shown how texts derived from interviews or from responses to open questions by different individuals can be analyzed both qualitatively and quantitatively with SNA. Concluding, this research has produced novelties at both the educational and the methodological levels. As concerns adult education, it was shown that i) LBMAR games are suitable for it, ii) adult education about them can be enhanced by following Keller’s ARCS model, iii) perception and satisfaction of adult learners depends on age, and iv) certain theories of adult education (i.e. constructivism and humanism) can be relevant when adult learners use LBMAR games such as “Ingress”. As concerns methods of educational research, this research suggested entirely new methods, for first time ever, for analyzing data that are derived from trainees' responses to open questions. These new methods are content analysis of the participants’ responses with the use of Jaccard indices and methods of SNA and can have a wider applicability to educational research.Existe un creciente interés por las aplicaciones educativas de la Realidad Aumentada (RA). Mientras que la mayoría de las aplicaciones de estas tecnologías se han examinado en el contexto de la educación infantil, nuestro conocimiento sobre su utilidad en la educación de adultos es deficiente y, en particular, más en la categoría de juegos de Realidad Aumentada Basada en la Localización (LBMAR), por lo que el objetivo de esta tesis es examinar las opiniones de los estudiantes adultos (jóvenes, de mediana edad y mayores) sobre un juego LBMAR, el "Ingress". Los principales problemas que aborda esta investigación comprenden cuestiones relacionadas con la utilidad de algunos componentes tecnológicos de la RA en la educación (secundariamente) y con aspectos de la formación de adultos mediante el uso de la RA (principalmente). En cuanto a los aspectos tecnológicos, es decir "¿cuál de los tres tipos de RA (basada en marcadores, sin marcadores, basada en la localización) se asocia más a los enfoques naturalistas y cuáles son sus ventajas relativas?", esta investigación demostró que los enfoques naturalistas aplicados a la RA basada en marcadores potencian la participación activa en entornos virtuales, motivan a los alumnos, promueven la implicación personal en la conquista de nueva información, ofrecen diferentes perspectivas del contenido y despiertan el interés por el conocimiento. En el caso de la RA sin marcadores, los diseños naturalistas fomentan la colaboración de los participantes en los juegos, mejoran la interactividad, ofrecen vistas panorámicas, visualización y la posibilidad de examinar los controles visuales. Además, los enfoques naturalistas aplicados a la RA basada en la localización son adecuados para el diseño de aplicaciones multidisciplinares, pueden utilizarse para la formación y tienen la posibilidad de diseñarse teniendo en cuenta la localidad y el contexto. El hecho de que, como se desprende de la literatura revisada por pares que se examinó, las tecnologías de RA basadas en la localización son más apropiadas para la educación y para los teléfonos smartphones, sugiere que podría ser interesante un examen más profundo de su utilidad potencial para la educación (y para la educación de adultos en particular). En cuanto a los aspectos educativos, que también constituyen el foco principal de la tesis, éstos se centran en la exploración de la utilidad del juego LBMAR "Ingress" en la educación de adultos, respondiendo a dos preguntas entrelazadas: a) ¿cómo evaluar las opiniones de los alumnos adultos sobre el juego LBMAR "Ingress"? y b) ¿qué piensan los alumnos adultos sobre este juego y cómo perciben sus características? Dar respuesta a estas preguntas equivale a recibir resultados adecuados de una investigación empírica, cuantitativa y cualitativa, que se diseñaría para explorar sus opiniones, puntos de vista y actitudes con respecto a este juego LBMAR. Por lo tanto, 45 personas adultas de Grecia, con edades entre 20 y 62 años, colaboraron como sujetos de esta investigación. Siguieron una breve formación informal introductoria por parte del investigador de esta tesis (sobre RA, realidad virtual, RA móvil, y sobre los juegos relacionados con estas tecnologías) y posteriormente se les dieron las instrucciones de cómo utilizar "Ingress" en un smartphone. La investigación cuantitativa se llevó a cabo antes y después de la formación y todos los alumnos participaron respondiendo a 31 preguntas cerradas del tipo Likert antes y después de la formación. La investigación cualitativa se basó en el análisis de sus respuestas a dos conjuntos diferentes de preguntas abiertas. El primer conjunto constaba de 5 preguntas de este tipo (a las que respondieron 24 participantes) y el segundo conjunto tenía 2 preguntas más amplias, a las que respondieron 36 participantes. La investigación cuantitativa mostró las ventajas para la educación de adultos de integrar el modelo ARCS en la fase de aprendizaje de un juego LBMAR. En concreto, se demostró que la utilización del conocido "modelo ARCS" de Keller (Atención - Relevancia - Confianza - Satisfacción) permitió clasificar las respuestas de los usuarios con respecto a sus interacciones con el juego y, también, es útil para evaluar la educación de adultos con juegos LBMAR. Las respuestas de los jugadores no cambiaron linealmente con su edad y el entrenamiento ha tenido un impacto diferente en cada grupo de edad de los alumnos. Además, los análisis estadísticos demostraron que el entrenamiento aumentó las puntuaciones de los factores del modelo ARCS. Otros resultados de esta investigación mostraron que los mayores de 36 años se centraron más en el hecho de que el juego "Ingress" es principalmente un juego geográfico y su escenario refleja interesantes debates sobre la evolución de la humanidad. Las opiniones de los participantes de los grupos de edad de 20-35 y >52 coincidieron en que el juego no tiene fases ociosas, que combina la emoción con la inseguridad y que es agradable jugar a nivel local a un juego de proporciones planetarias. Otra observación relacionada con la edad se refería a las respuestas a la pregunta ("¿Cómo te sientes cuando dotas al espacio geográfico de preferencias personales?") entre grupos de edad que coincidían: los dos primeros grupos de edad (20-30) y (30-40) estaban más de acuerdo que los dos últimos (40-50) y (50-60). Sin embargo, en la pregunta "¿Crees que el juego ofrece oportunidades para aprender y enseñar geografía, aprovechando tus conocimientos geográficos previos?" hubo un solapamiento en las respuestas de los participantes entre los grupos de edad. En cuanto a la primera pregunta, el concepto más crítico fue: "los usuarios sienten una especie de nostalgia", seguido del concepto "los usuarios consideran los portales como creaciones personales". En el caso de la segunda pregunta, el concepto más crítico fue que los participantes creen que el juego ofrece oportunidades totalmente nuevas para la educación en geografía en comparación con sus experiencias anteriores. Esto fomenta una evidencia de los enfoques constructivistas de la educación de adultos y, también, la relevancia de algunas otras teorías prominentes de la educación de adultos, como el humanismo. Metodológicamente, esta investigación demostró también que el análisis de contenido es un método valioso para explorar las opiniones y actitudes de los usuarios adultos hacia los juegos MAR y los índices de Jaccard pueden utilizarse para explorar cuantitativamente los temas que surgen del análisis de contenido. El análisis de contenido se realizó sobre las respuestas de los usuarios de forma cualitativa para identificar las frases características que expresan actitudes y opiniones. Para la evaluación cuantitativa de las similitudes entre las respuestas de cada pregunta y subconcepto, se calculó el índice de similitud de Jaccard por parejas para cada par de participantes. Además de los índices de Jaccard y de ampliar el alcance de los nuevos métodos de análisis de contenido, esta tesis muestra cómo utilizar el Análisis de Redes Sociales (Social Networks Analysis - SNA) para modelar los mapas conceptuales, abriendo así excelentes oportunidades para crear visualizaciones de los conceptos y sus interrelaciones. Los aspectos cuantitativos del análisis SNA (es decir mediante el uso de la centralidad radial y la centralidad de la información) proporcionan mecanismos adecuados para medir las relaciones internas en los mapas conceptuales (además de la inspección visual) que de otro modo no serían visibles. El uso del SNA permitió la clasificación de las respuestas de los usuarios con respecto a su interacción con el juego y, por lo tanto, fue un enfoque fructífero para la educación que involucra los juegos MAR. Además, con esta novedad, se muestra cómo los textos derivados de las entrevistas o de las respuestas a las preguntas abiertas de diferentes individuos pueden ser analizados tanto cualitativamente como cuantitativamente usando SNA. En conclusión, esta investigación ha aportado novedades, tanto a nivel educativo como metodológico. En lo que respecta a la educación de adultos, se ha demostrado que i) los juegos LBMAR son adecuados para ella, ii) la educación de adultos sobre ellos puede mejorarse siguiendo el modelo ARCS de Keller, iii) la percepción y la satisfacción de los alumnos adultos depende de la edad, y iv) ciertas teorías de la educación de adultos (es decir, el constructivismo y el humanismo) pueden ser relevantes cuando los alumnos adultos utilizan juegos LBMAR como "Ingress". En cuanto a los métodos de investigación educativa, esta investigación sugirió métodos totalmente nuevos para analizar los datos que se derivan de las respuestas de los alumnos a las preguntas abiertas. Estos nuevos métodos son el análisis de contenido de las respuestas de los participantes con el uso de los índices de Jaccard y los métodos de SNA y pueden tener una aplicabilidad más amplia a la investigación educativa

Wireless distributed intelligence in personal applications

Tietokoneet ovat historian kuluessa kehittyneet keskustietokoneista hajautettujen, langattomasti toimivien järjestelmien suuntaan. Elektroniikalla toteutetut automaattiset toiminnot ympärillämme lisääntyvät kiihtyvällä vauhdilla. Tällaiset sovellukset lisääntyvät tulevaisuudessa, mutta siihen soveltuva tekniikka on vielä kehityksen alla ja vaadittavia ominaisuuksia ei aina löydy. Nykyiset lyhyen kantaman langattoman tekniikan standardit ovat tarkoitettu lähinnä teollisuuden ja multimedian käyttöön, siksi ne ovat vain osittain soveltuvia uudenlaisiin ympäristöälykkäisiin käyttötarkoituksiin. Ympäristöälykkäät sovellukset palvelevat enimmäkseen jokapäiväistä elämäämme, kuten turvallisuutta, kulunvalvontaa ja elämyspalveluita. Ympäristöälykkäitä ratkaisuja tarvitaan myös hajautetussa automaatiossa ja kohteiden automaattisessa seurannassa. Tutkimuksen aikana Seinäjoen ammattikorkeakoulussa on tutkittu lyhyen kantaman langatonta tekniikkaa: suunniteltu ja kehitetty pienivirtaisia radionappeja, niitten ohjelmointiympäristöä sekä langattoman verkon synkronointia, tiedonkeruuta ja reititystä. Lisäksi on simuloitu eri reititystapoja, sisäpaikannusta ja kaivinkoneen kalibrointia soveltaen mm. neurolaskentaa. Tekniikkaa on testattu myös käytännön sovelluksissa. Ympäristöälykkäät sovellusalueet ovat ehkä nopeimmin kasvava lähitulevaisuuden ala tietotekniikassa. Tutkitulla tekniikalla on runsaasti uusia haasteita ihmisten hyvinvointia, terveyttä ja turvallisuutta lisäävissä sovelluksissa, kuten myös teollisuuden uusissa sovelluksissa, esimerkiksi älykkäässä energiansiirtoverkossa.The development of computing is moving from mainframe computers to distributed intelligence with wireless features. The automated functions around us, in the form of small electronic devices, are increasing and the pace is continuously accelerating. The number of these applications will increase in the future, but suitable features needed are lacking and suitable technology development is still ongoing. The existing wireless short-range standards are mostly suitable for use in industry and in multimedia applications, but they are only partly suitable for the new network feature demands of the ambient intelligence applications. The ambient intelligent applications will serve us in our daily lives: security, access control and exercise services. Ambient intelligence is also adopted by industry in distributed amorphous automation, in access monitoring and the control of machines and devices. During this research, at Seinäjoki University of Applied Sciences, we have researched, designed and developed short-range wireless technology: low-power radio buttons with a programming environment for them as well as synchronization, data collecting and routing features for the wireless network. We have simulated different routing methods, indoor positioning and excavator calibration using for example neurocomputing. In addition, we have tested the technology in practical applications. The ambient intelligent applications are perhaps the area growing the most in information technology in the future. There will be many new challenges to face to increase welfare, health, security, as well as industrial applications (for example, at factories and in smart grids) in the future.fi=vertaisarvioitu|en=peerReviewed

The Multimodal Tutor: Adaptive Feedback from Multimodal Experiences

This doctoral thesis describes the journey of ideation, prototyping and empirical testing of the Multimodal Tutor, a system designed for providing digital feedback that supports psychomotor skills acquisition using learning and multimodal data capturing. The feedback is given in real-time with machine-driven assessment of the learner's task execution. The predictions are tailored by supervised machine learning models trained with human annotated samples. The main contributions of this thesis are: a literature survey on multimodal data for learning, a conceptual model (the Multimodal Learning Analytics Model), a technological framework (the Multimodal Pipeline), a data annotation tool (the Visual Inspection Tool) and a case study in Cardiopulmonary Resuscitation training (CPR Tutor). The CPR Tutor generates real-time, adaptive feedback using kinematic and myographic data and neural networks

Feasibility and Efficacy of a Recess-Based Combined Fitness Intervention on Cognition and Academic Performance in Elementary School Children

Youth physical activity and fitness have been reported to influence cognition and academic related outcomes. Despite the potential benefits of muscular fitness, few intervention studies have examined the impact of an intervention that has incorporated both cardiorespiratory and muscular fitness training on cognition and academic performance in children. Previous studies have mainly been implemented either during the school day or immediately after-school. Although recess may be an ideal time to promote physical activity because it does not compete with other academic demands, it has been an understudied setting. Therefore, the purpose of this dissertation project was to examine the feasibility, acceptability, and the preliminary efficacy of a 3-month recess-based combined fitness (i.e., cardiorespiratory and muscular fitness) program on cognition and academic performance in elementary school-age children. Two elementary schools were randomly assigned to either the combined fitness intervention or control group. The intervention was implemented during recess for 15 minutes/weekday for 13 weeks while the control group continued participating in their regular recess sessions. Process evaluation data (feasibility and acceptability) were collected throughout the intervention. Executive functions, classroom behavior, fitness, and physical activity were collected at baseline and 3-months. Process evaluation data showed that the program achieved high intervention session intensity dosage (mean percentage of maximal heart rate = 58.0±5.8%), number of implemented sessions (88%), and percentage of sessions implemented as planned (78% of sessions). However, intervention session intensity dosage based on accelerometry (% of time spent in moderate-to-vigorous activity: 41.7±14.5%) and participation (19.4% attendance rate) were lower than expected. Moderate-to-vigorous physical activity during recess sessions was significantly higher in the intervention group, compared to the control group (intervention group = 41.7±2.1%; control = 30.4±0.2,

Bridging the physical and virtual with mobile media

This thesis examines how mobile technologies can contribute towards bridging physical and virtual space through interactive, and location-specific, media experiences. Building on a research analysis of contextual discussions and precedents, it is noticeable that there is a discord between physical and virtual space usage as they are often utilised in different situational settings. This thesis therefore develops a mobile application as a wider investigation into how the physical setting and live data can be used to achieve a better link for contextualised content between the physical and virtual in urban areas. It explores this by making a location specific media experience, where the limits of the physical space are incorporated as boundaries in the virtual environment. Further to this, live data is used to influence the dynamics of the environment so that conditions are reflective of the physical world. These investigations are utilised with Augmented Reality, providing an end application that allows the viewer to physically explore urban space within an interactive mobile media experience. This approach offers a new perspective in urban space exploration and mobile media design, highlighting that contextual significance in media experiences are important aspects to consider and design for. Ultimately, such approaches may lead to larger narratives and experiences encompassing entire cities, or other diverse geographies
