TL;DR: A data communication model is proposed that allows translation of IoT data into XR objects, events or scenarios, and is discussed by discussing future trends for XR and IoT.
Abstract: The multiple branches of Extended Reality (XR) are pioneering new ways to interact with digital content, both in real and virtual worlds. The Internet of Things (IoT) is also pioneering new real-world scenarios and use cases by taking advantage of sensed data and automation. These technologies are bridging the gap between the real world and the digital world.In this paper we present XR and IoT technologies, explaining their concepts, popular devices and challenges. We then provide a study on the current applications of XR technologies in IoT scenarios. These include visualization of IoT data in Virtual Reality (VR), network management of IoT devices in Augmented Reality (AR) or 3D visualization of smart buildings and cities. In order to tackle the challenge of incorporating IoT data into XR applications, we propose a data communication model that allows translation of IoT data into XR objects, events or scenarios. We conclude by discussing future trends for XR and IoT.

TL;DR: An immersive tool that intends to aid the traditional motor rehabilitation therapies, in order to both motivate and encourage the patients to perform therapeutic exercises, by having them distracted from their handicaps is proposed.
Abstract: Post-stroke rehabilitation should start as soon as possible, once the patient’s condition is considered stable. As rehabilitation must be intensive and repetitive, this can lead to problems with patient motivation and engagement. This paper proposes an immersive tool that intends to aid the traditional motor rehabilitation therapies, in order to both motivate and encourage the patients to perform therapeutic exercises, by having them distracted from their handicaps. Since different people have different needs, the game dynamically adapts to the user, by increasing or decreasing its level of challenge. Following the proposed solution principles a serious game was implemented and evaluated with positive results.

TL;DR: The main advantage of a newly developed remote laboratory in comparison with the previous Matlab based laboratories consists in the fact that using the websocket technology the client interface can be run within the Internet browser and no dedicated application is needed.
Abstract: This paper presents a new architecture for remote laboratories that is based on Matlab and websockets. The Matlab sever uses the MatlabWebSocket library and then the client can be realized in JavaScript. Moreover, the visualization of the remote laboratory on the client side is realized in 3D using Three.js JavaScript library. As an example, the three-tank real hydraulic system has been modeled in 3D and this model has been connected via Internet to the real system. This allows users to perform different control strategies on the real hydraulic system with 3D visualization of its dynamical behavior. The main advantage of a newly developed remote laboratory in comparison with the previous Matlab based laboratories consists in the fact that using the websocket technology the client interface can be run within the Internet browser and no dedicated application is needed.

TL;DR: A system for object detection and classification which gets by with less resources and based on the MSCOCO data set, both the quality of the object classification and the computing time are evaluated.
Abstract: Object detection and classification is an increasingly important field of research in machine learning. Currently, powerful GPUs (Graphics Processing Units) are used to perform the computation-intensive operations in the shortest possible computing time. However, these systems are associated with high costs. In this paper a system for object detection and classification is developed, which gets by with less resources. This should minimize the costs while keeping the performance acceptable for the target application. To keep the costs low, a Raspberry Pi3 is used as development platform in connection with a Movidius stick for the outsourcing of the ANN. After explaining the theoretical basics of object detection and ANNs, this paper shows the implementation process of the selected hardware and software. For the evaluation of this system the algorithms YOLO and MobileNet are used and pre-trained models are used as basis. Based on the MSCOCO data set, both the quality of the object classification and the computing time are evaluated.

TL;DR: The aim was to study and developed algorithms that allow the efficient recirculation of water, allowing electricity savings to be around 40% compared to more traditional systems.
Abstract: Precision agriculture nowadays has great importance as it brings together the knowledge acquired through traditional cultivation techniques with precision and technological automation. One of the inherent techniques of precision agriculture is hydroponics, with plants growing using aqueous solutions and without soil availability. Although NFT (Nutrient Film Technique) systems are already well-developed systems, there is a big difference between home projects and highly automated processes, which in turn require high investment values. Among other things, in this work, the aim was to study and developed algorithms that allow the efficient recirculation of water, allowing electricity savings to be around 40% compared to more traditional systems.

TL;DR: The present work shows the first steps of this project in terms of courses at UNED in which RL was used, its use in physics teacher training workshops and itsUse in high school.
Abstract: There is no doubt that experimental work is fundamental in the teaching of physics, however neither the accurate spaces nor the equipment for its fulfillment are always available. Taking into account the range of Remote Labs (RL) as resources for teaching and learning, the Open State University (UNED) from Costa Rica has started the Remote Testing Lab to develop and encourage the use of RLs in the institution as well as boosting its use in other university and high school institutions within the country. The present work shows the first steps of this project in terms of courses at UNED in which RL was used, its use in physics teacher training workshops and its use in high school.

TL;DR: The goal is to build an automated breathing relaxation system that is based on a closed-loop, implicit interaction and that harnesses known mechanisms of physiological synchrony found in human-human interaction.
Abstract: A number of health-related issues can be attributed to occupational and chronic stress. Interactive immersive Virtual Reality environments have been shown to be beneficial in healthcare and mental wellbeing by enabling effective interventions such as stress management and behavioural therapy. Our goal is to build an automated breathing relaxation system that is based on a closed-loop, implicit interaction and that harnesses known mechanisms of physiological synchrony found in human-human interaction. In this demo, we will show the Virtual Human Breathing Relaxation System where the user’s breathing rhythm is influenced using an ecologically valid physiological signal, i.e. the breathing behaviour of a virtual human. By continuously adapting the virtual human’s breathing rhythm the system aims to bring the participants breathing behaviour to a rhythm that allows them to feel more relaxed.

TL;DR: The NanoSen-AQM platform should provide free access to the public and low-cost of entry for sensor owners willing to share their data, and use state-of-the-art techniques from Machine Learning and mobile and web development frameworks.
Abstract: The interest in the quality of air is likely to increase, as the public concern for health and environmental issues is on the rise. So far, most data available comes from a small numbers of government-owned sensors, lacking a wide coverage of the entire reality. Improving the amount of data available thus involves reducing the cost of sensors and make their readings accessible to the public. The NanoSen-AQM project aims to do precisely that. Create and use vast numbers of low-cost nano-sensors, to make their data accessible for the public. To achieve such an ambitious goal, the project will use state-of-the-art techniques from Machine Learning and mobile and web development frameworks. As a result, the NanoSen-AQM platform should provide free access to the public and low-cost of entry for sensor owners willing to share their data.

TL;DR: It is shown how agile methodologies, widely used in industry and manufacturing, combined with online experimentation, can be both applied to a CS2-based course in the era of data engineering.
Abstract: In introductory programming courses, there is a need for a change in teaching strategies for practicing programming, which must be influenced by productive learning experiences connected with real world scenarios and methodologies. The abundance of data from different sources, online experimentation, and simulators and virtual/remote labs should also play a fundamental role when we think in new teaching strategies for these courses. In this paper, we show how agile methodologies, widely used in industry and manufacturing, combined with online experimentation, can be both applied to a CS2-based course in the era of data engineering. And, then, a new approach of teaching lab classes in CS2-based course is introduced, benefiting from the Scrum framework, to student-centered learning activities on lab classes, and from the concept of Jupyter notebook to online experimentation.

TL;DR: 16 breast cancer patients have been exposed to the two versions of the virtual environment to evaluate effectiveness, pleasantness, overall satisfaction with the technique and sense of presence, as well as the impact on the emotional dimensions of valence, arousal and control.
Abstract: A number of studies demonstrated that virtual reality (VR) featuring pleasant scenarios and relaxing narratives is effective in promoting relaxation in users, both in healthy and pathological contexts. One important field for application of relaxing VR is breast cancer, because of therapy-related distress and changes in body imagine experienced by patients during the care process. However, comparisons between different relaxation techniques adapted to virtual reality are rare. In the present study, the same virtual environment has been integrated with audio narratives designed according to two different relaxation techniques (respiration control and body scan). As initial exploration, 16 breast cancer patients have been exposed to the two versions of the virtual environment to evaluate effectiveness, pleasantness, overall satisfaction with the technique and sense of presence, as well as the impact on the emotional dimensions of valence, arousal and control. Discussion offers recommendations for the content properties of VR for relaxation for breast cancer patients.

TL;DR: This demonstration showcases the use of reconfigurable logic to implement edge computing for IoT devices able to provide specific information from raw data produced from some sensor, e.g. a camera or microphone, instead of the raw data itself.
Abstract: This demonstration showcases the use of reconfigurable logic to implement edge computing for IoT devices able to provide specific information from raw data produced from some sensor, e.g. a camera or microphone, instead of the raw data itself. In what concerns the embedded processing capabilities, the focus is image processing using convolutional neuronal networks (CNN). This approach is clearly distinct from the current trends in IoT devices of using cloud computing to process the collected data. We intend a twist on the established paradigm and pursue an edge computing approach. Since we are targeting small and simple devices, we need some low power solution for the CNN computation. The demonstration will be made on a Terasic DE1 (SoC) reconfigurable system, with a field programmable gate array (FPGA), and hardwired ARM processor to build the IoT device. The collected data from the CNN computation, is transmitted using an IoT protocol to a broker.

TL;DR: The VISIR dashboard (VISIR-DB) is a learning analytics tool connected with the VISIR remote lab that helps a teacher analyze and understand better how the students are using the remote lab during their learning process on analog electronics.
Abstract: The VISIR dashboard (VISIR-DB) is a learning analytics tool connected with the VISIR remote lab. In VISIR, every action performed by a student from the interface over the remote laboratory and back is logged and recorded. VISIR-DB helps visualizing, in a fast and deep way, the recorded logs from this communication. Using this tool, a teacher can analyze and understand better how the students are using the remote lab during their learning process on analog electronics. With this information, the VISIR platform can be improved and the use of remote labs can be better understood.

TL;DR: The World Pendulum Alliance experimental network as a gravity mapper, presents a strong basis to address students in a non-conventional way, empowering them inside an inquiry learning space.
Abstract: Pendulum motion as a prolific experimental scenario has been used by physics teachers and researchers at least since the 17th century. The variability of pendulum models allows the study of several mechanical phenomena and gives the opportunity to validate distinct mathematical features of the dynamical and kinematic event. These experimental setups could be used remotely, in a way it could teach physics to students in the pre-university and university level, regardless budget limitations of the particular institution accessing the experiment. The World Pendulum Alliance experimental network as a gravity mapper, presents a strong basis to address students in a non-conventional way, empowering them inside an inquiry learning space.

TL;DR: A Mixed Reality simulation in the first semester of an engineering study program, students will have the opportunity to experience the digital transformation in a production company and the development and design of a specific learning environment, a solution space, which is developed by experimenting and creative exploration.
Abstract: The Paper addresses a current polylemma in engineering education. Based on existing theories and findings on mixed reality and game-based learning it demonstrates – initially on a conceptual level – a possibility for diversity-oriented, application-related, experience-oriented engineering education. In a second step it describes the development and design of a specific learning environment, a solution space, which is developed by experimenting and creative exploration as well as on the basis of strong theory: In a Mixed Reality simulation in the first semester of an engineering study program, students will have the opportunity to experience the digital transformation in a production company. In a virtual production plant, they will be working together in a network of engineering consultant teams and acquiring necessary methodological and technical knowledge in various modular units. They get familiar with up-to-date automation technologies, work out a state of the art [1], pitch for "budgets" for their projects to reach the next level etc. In the modular production unit students will choose appropriate technologies and plan a modular manufacturing shop floor. In addition, methodological and technical topics are linked and reflected in real hands-on project work. Virtual, augmented and real settings are combined in one Mixed Reality Game. The design offers the opportunity to be interlinked and practiced in higher project modules.

TL;DR: P PuzzlEx, an experimentation environment for control engineering virtual and remote labs that enables the use of interactive laboratories already created without the need to rewrite their code, is presented.
Abstract: This work presents PuzzlEx, an experimentation environment for control engineering virtual and remote labs. This environment not only allows students to make interactive use of the lab but also to define and run customized experiments. For this purpose, an intuitive visual programming language that communicates internally with the laboratory is used. The main advantage of this environment is that it enables the use of interactive laboratories already created without the need to rewrite their code. Students acquire a broader knowledge of the plant or model used and experience in handling problems like those found in real life thanks to the possibility of programming their own experiments. Also, teachers can offer new tasks to students that cover more curricular competencies using the same interactive labs. Two experiments are presented with a Furuta pendulum system used by control engineering students to demonstrate the usefulness and possibilities offered by the environment.

TL;DR: It is concluded that unit-specific advanced statistical calibration methods are needed to obtain reliable results with the low cost sensors devices in urban areas.
Abstract: Low-cost sensor technology can potentially make revolutionary changes in our current air pollution monitoring paradigm in urban areas. However, the widespread adoption of low-cost sensor technology is still not feasible due to a number of limitations regarding sensitivity, accuracy and comparability. In this study we report the results from preliminary laboratory and in-field tests carried out within the TECNAIRE-cM project for commercial NO 2 and O 3 sensors including both, solid-state and electrochemical technologies. The ultimate goal is to understand the current capabilities of this technology and the prospects to incorporate it in both research and routine measurement or urban air quality. We found significant performance differences although none of the devices tested could provide satisfactory results in real-world conditions. We conclude that unit-specific advanced statistical calibration methods are needed to obtain reliable results with the low cost sensors devices in urban areas.

TL;DR: The efforts of creating RC v2.0, a VR-based software system for cognitive rehabilitation that presents different cognitive training tasks that take place in 8 realistically modeled 3D environments, that are personalized to the patient clinical profile and also implements automatic difficulty adaptation are presented.
Abstract: Cognitive impairments are among the most common age-related disabilities worldwide. Literature has shown that cognitive training using Virtual Reality (VR) systems can be a valid and effective solution for cognitive rehabilitation. Virtual environments can be easily customized to deliver very specific training by controlling the presentation of stimuli and keeping track of the user responses. Reh@City (RC) is a virtual reality simulation of a city where patients can train a variety of cognitive skills while performing simulated activities of daily living. An initial prototype of this city with four environments was clinically validated with a stroke sample, and the encouraging results motivated further iterations and improvements in the RC, in terms of its tasks, interaction with the content, and task adaptation. This paper presents the efforts of creating RC v2.0, a VR-based software system for cognitive rehabilitation that presents different cognitive training tasks that take place in 8 realistically modeled 3D environments, that are personalized to the patient clinical profile and also implements automatic difficulty adaptation.

TL;DR: This article presents Crumble as a platform commonly used in educational robotics and includes the results obtained through educational experiences based on the use of this platform.
Abstract: Educational robotics is an interdisciplinary teaching environment based on the use of robots and electronic components as a common thread to enhance the development of children’s skills and competencies. It works especially in the STEAM disciplines, although it can also cover other areas such as linguistics, geography and history. The main entry barriers to the use of educational robotics could be to answer the questions: which platform is best to use, which platform allows me to travel more in the learning process, how much effort do I need to devote to prepare educational content with the platform I choose, and how much budget do I need for my students to develop their skills with educational robotics? Throughout this article we present Crumble as a platform commonly used in educational robotics. We also include the results obtained through educational experiences based on the use of this platform. Finally, throughout the conclusions, we give answers to the questions posed above.

TL;DR: A virtual lab session that visualizes the effects of different design and implementation decisions that allows students to realize for themselves which aspects or their solution are adequate, and to identify any problems that they still have to resolve.
Abstract: While object-oriented programming offers an almost unlimited number of possibilities to solve a certain task, only a small subset of these solutions is really adequate from a technical perspective. Novices in the art usually find it rather hard to realize which of the design decisions they took are good, and which violate the principles of object-orientation and thus will lead to low quality code on the long run. To support students in learning to truly comprehend the object-oriented programming paradigm, we designed a virtual lab session that visualizes the effects of different design and implementation decisions. This immediate visual feedback is easy to understand in an intuitive way. Thus it allows students to realize for themselves which aspects or their solution are adequate, and to identify any problems that they still have to resolve. Three years of experience with this virtual lab session indicate that its design is well suited to provoke, and thus make visible, typical misconceptions and error patterns that occur at early stages of learning the object-oriented programming paradigm.

TL;DR: This work presents an experimental demo of a smartbox for Industry 4.0 scenarios, allowing sensing, monitoring and data acquisition, depending on the communication protocol used for real time applications: OPC UA or MQTT.
Abstract: Constant search for efficiency and productivity has led to innovation on the factory shop floor, representing an evolution of the current production systems combined with new technologies of industrial automation and information technology. This work presents an experimental demo of a smartbox for Industry 4.0 scenarios, allowing sensing, monitoring and data acquisition. We have tested two different approaches, depending on the communication protocol used for real time applications: OPC UA or MQTT. Raspberry Pi’s platform act as an OPC UA server or MQTT broker, respectively. From the measurements, data stored in a cloud server can be accessed remotely with improved security and visualized from a computer dashboard. One of the conclusions that can be drawn is that both protocols allow data from the smartbox to be stored and easily monitored from a smartphone application or a computer web interface. MQTT is a good option in communications requiring very low bandwidth. However, there is a lack of suitable libraries to program alarm features for OPC UA Servers.

TL;DR: A German technical university analyzes one of its remote labs to identify technological potential for future-oriented teaching and learning in light of the required competences for the ‘Working World 4.0’, and shows possibilities for future critical research and constructive development in this area.
Abstract: The demands of so-called Industry 4.0 are reshaping the working world of future engineers. Therefore, it is very likely that these technological developments soon will affect higher education institutions with increasing intensity. For years, there has been a vivid discussion on the respective competence students would need to develop in order to face emerging technology changes. To slightly tackle this question of what might be expected of future engineers, a German technical university analyzes one of its remote labs to identify technological potential for future-oriented teaching and learning in light of the required competences for the ‘Working World 4.0’. In a first step, based on current scientific studies, relevant Industry 4.0 competences are identified and summarized in a structuring grid. In a second step, the selected remote laboratory is analyzed as an example case with regard to explicit and implicit learning objectives, which address the identified competence requirements of the structuring grid. It could be shown that this didactic setting has the potential to recognize the complexity of the Working World 4.0 and 'digitization' in the form of a remote laboratory, opening up a multitude of possibilities. However, the results also show that in the examined case example laboratory only a few competences of the technical competence area are addressed in the context of Industry 4.0, since the lack of interdisciplinarity significantly limits the promotion of these competences. This shows possibilities for future critical research and constructive development in this area.

TL;DR: An initiative to collect empirical evidence to support the design-belief that quantity leads to quality and to use the activity and its results as part of a pedagogical strategy to enhance students’ awareness of the connections between quantity and quality during ideation.
Abstract: Traditional engineering methods are considered unsuitable for the development of usable and engaging interactive systems such as online experimentation and simulation software. For systems involving users, user-centric design approaches are more appropriate. The ideation stage of design involves exploring the space of opportunities. One commonly held view in design disciplines is that quantity leads to quality. Yet, for related non-design disciplines such as engineering, quantity is often regarded as a negative characteristic associated with low quality. Focusing on quality alone may lead to inferior user experience and ineffective systems. This study describes an initiative to (1) collect empirical evidence to support the design-belief that quantity leads to quality and (2) to use the activity and its results as part of a pedagogical strategy to enhance students’ awareness of the connections between quantity and quality during ideation. A class of 100 computer science students was divided into two groups. Both groups were given the same task to design a text-input strategy for individuals with motor disabilities but with different focuses: one group was asked to focus on quality of ideas and the other group on the quantity of ideas. The results show that the students who focused on quantity of ideas produced better quality concepts compared to the students that focused on quality. The results were presented to and discussed with the students as a part of the learning process.

TL;DR: The World Pendulum Alliance is a federated initiative of several universities to create a network of "latitude providers" to allow the mapping of local gravity across the globe.
Abstract: Some experiments related to Earth’s geophysical characteristics need a globally distributed data acquisition, especially those depending on geographic factors such as latitude. The World Pendulum Alliance is a federated initiative of several universities to create a network of "latitude providers" to allow the mapping of local gravity across the globe. In parallel, a dissemination project encompasses training initiatives to educate local agents in view of physics teaching. The World Pendulum experiment is already in production at e-lab, in Instituto Superior Tecnico – Universidade de Lisboa, and the reproduction of 20 primary experiments, located at partner universities, and 120 secondary experiments, to be deployed by partner universities, is foreseen in the next two years.

TL;DR: A collaborative learning activity that allows students to use real sensors and systems in a laboratory environment that covers sensor-based end-node design, communication, system design, data presentations, and collaborative discussions.
Abstract: Internet of Things (IoT) is a network-based system of devices exchanging different kinds of data for decision making. It has multi-disciplinary facets which make it tricky to teach as a university course. Students must be provided with practical learning opportunities to understand the complexities of the Internet of Things applications. This can be challenging as IoT has evolved rapidly with time. This paper introduces a collaborative learning activity that allows students to use real sensors and systems in a laboratory environment. A smart farming based agricultural application is a use case for the laboratory coursework. Real sensors and nodes are used to build a working farm IoT system. It covers sensor-based end-node design, communication, system design, data presentations, and collaborative discussions.

TL;DR: This study shows significant improvements under World Health Quality of Life Scale in domains like Social Relations and also in Friends Satisfaction domain of the Satisfaction with Social Support Scale.
Abstract: Benefits of augmented reality games in physical and cognitive dimensions have been demonstrated before but not many works have addressed the social dimensions which are quite important for the overall quality of life. The objective of this work is to assess the impact of a recently developed platform for senior exercise with augmented reality games (exergames) in the perception of quality of life and socialization of older adults institutionalized in nursing homes. We describe a 3 months study with 18 participants (85.28 ± 6.02 years) divided into three groups of different functional abilities (Group-1 n=6, Group 2 n=5, Group 3 n=7), with a weekly session of exergames of approximately 90 to 120 minutes. Our study shows significant improvements under World Health Quality of Life Scale in domains like Social Relations and also in Friends Satisfaction domain of the Satisfaction with Social Support Scale. Differences between groups were also found regarding Satisfaction with Social Activities. Some positive and significant correlations were found between the number of group sessions attendance and the perceived quality of Social Relations and System Usability. We, thus, conclude that our exergame sessions have several benefits for quality of life perception and social relations.

TL;DR: The present work originates in the Project "Educational Modules for Electric and Electronic Circuits Theory and Practice following an Inquiry-based Teaching and Learning Methodology supported by VISIR", carried out with the support of the Erasmus+ Programme.
Abstract: The present work originates in the Project "Educational Modules for Electric and Electronic Circuits Theory and Practice following an Inquiry-based Teaching and Learning Methodology supported by VISIR", carried out with the support of the Erasmus+ Programme. Remote labs can provide a framework where physical experiments can be developed for STEM (Science, Technology, Engineering and Mathematics) education. Although remote labs have been in use for over a decade now in several countries and levels of education, their use is not yet being generalized in Latin America. Through the VISIR+ International Cooperation Project from the Erasmus+ Programme, five higher education institutions from Latin America have incorporated de VISIR remote lab in order to carry out experiments with electric and electronic circuits. In the present work, the results of the study developed at Universidad Nacional de Rosario within the framework of the aforementioned project are shown.
