Abstract: This paper describes the design and development of a novel Massive Open Online Course (MOOC) on industrial electronics circuits. It is the first MOOC that, besides the usual features of these courses, includes the extensive use of a real remote laboratory dedicated to practices in electronic circuits. Although the nature of a MOOC is completely open, this course targets especially people with at least basic circuits knowledge, related with the demand on industrial sector of labour markets. As said, the core objective of the course is to learn practical competences in basic electronic circuits. This is possible by implementing the remote laboratory for electronic circuits' practices VISIR (Virtual Instrument Systems in Reality) within the MOOC to allow online, real time, delivery of such practices-which makes this MOOC a first of its kind. The paper presents the design and development of the MOOC. We show also some preliminary results in the middle of the course that is running, with more than 2200 students enrolled, during 5 months since May.

Abstract: The paper describes two dynamic monitoring systems installed in civil engineering structures, a footbridge and a suspended stadium roof. These systems are used for characterization of environmental and operational effects and, in the limit, for the early detection of damage. Some examples of collected data and results are presented.

Abstract: This demonstration shows an Augmented Reality tool to support teaching chemistry. The understanding of spacial relations in and between molecules is an essential part that has to be understood by students to learn chemistry As nowadays the techniques to show and simulate molecular behaviors get faster and better, 3D applications to show the molecules become more and more popular also in schools. Augmented Chemical Reactions is an application that shows the 3D spatial structure of molecules as well as the dynamics of the atoms in and between molecules. This application does not use the commonly used 3D user interface of mice and keyboards to move and rotate the virtual objects but it makes use of an intuitive 3D user interface. This 3D User interface is an direct manipulation user interface using the augmented reality technique. With this user interface it enables the users to better understand the spacial structure of the shown geometries.

Abstract: In this paper we present a mobile application and solution for accurate smart indoor positioning. Smart society applications do normally require user location, specifically, in indoor environments high accuracy can enrich augmented or virtual reality, gaming, in-building guidance or support for ambient assisted living. We use encoded ultrasonic signals and TDMA protocol to obtain fine-grained distance measurements. Signals are emitted from a set of low cost ultrasonic local positioning systems, operating around 41kHz. An acquisition module, based on a MEMs microphone and a microcontroller, digitizes at 100kHz the incoming signals and send them over an USB protocol to the mobile device for their processing. We have implemented an Android Application that computes the Time Difference of Arrival (TDOA) to estimate the current position and display it in the mobile screen. Several users can compute their positions autonomously and user privacy is protected. The application can be configured for different encoding techniques and modulation schemes according to the environment requirements. Absolute error less than 5 cm is achieved in a 5×6m complex environment in 85% of the cases for an average position refresh period of 200ms.

Abstract: This paper is about the use of commercial wrist wearables in education, more specifically, about how to support smart education in the context of new smart universities. Wrist wearable devices such smartwatches or smartbands include a variety of sensors that can be used to collect physiological and activity-related data about a subject, for example a learner or a teacher, and estimate insightful features about him. This paper reviews the current state of the art of projects and initiatives based on the use of these devices, the types of wearables available nowadays and the main problems and issues involved for educational purposes: data collection, data integration, sensor accuracy, etc. In the paper, we also introduce our developments towards the provision of sleep and stress indicators taking advantage of these devices. We distinguish among services for students, for teachers and for developers.
