About

Augusto Sousa (m) got his PhD in 1996 in the Faculty of Engineering of University of Porto, Portugal, in the area of Computer Graphics/Image Synthesis and Parallel Computing. He has been teaching in the same Faculty since 1983, in areas related to Computer Architectures and Computer Graphics.

Currently, he is member of the Executive Board of FEUP, being the Vice-President of the Academic Affairs Council. Between 2008 and 2014, he was director of MIEIC - Master in Informatics Engineering and Computing (a 5 years master program) and between 2000 and 2003, he was a member of the first Executive Board of the Bachelors in Journalism and Communications Sciences of UPorto. He is member of the Scientific Committee of ProDEI - Doctoral Program in Informatics Engineering.

Since 1985, he has been a researcher in INESC/INESC Porto, where he was the Coordinator of the Information Systems and Computer Graphics Unit. He was supervisor of two doctoral theses, in " Optimization of Visualization in Large 3D Scenes" and in " Spatio-Temporal Data Storage, Processing and Visualization", as well as co-supervisor of three doctoral thesis in "Image Synthesis", "Virtual reality" and "Automatic Modeling of Virtual Urban Environments. He was also Supervisor of several masters' theses in various areas of Computer Graphics, Virtual Reality and Geographical Information Systems.

A. Augusto de Sousa was involved in several R&D projects related to Advanced/Intuitive Interaction, Image Synthesis and Virtual Reality. He was involved in an European project (IST-2000-28169, “Smartsketches”) and was the responsible researcher for several FCT (Portuguese Foundation of Science and Technology) financed projects, mainly in two areas: Expeditious Modelling and Visualization of Urban Virtual Environments, and Spatio-Temporal Data Processing and Visualization.

As a member of the Executive Board of the Portuguese EUROGRAPHICS Chapter, he was, in two different periods of time, President, Vice-President and Treasurer, as well as a member of the Executive Committee of the EUROGRAPHICS Association itself (by inherence).

Abstract
Teaching complex assembly and maintenance skills to human operators usually requires extensive reading and the help of tutors. In order to reduce the training period and avoid the need for human supervision, an immersive teaching system using spatial augmented reality was developed for guiding inexperienced operators. The system provides textual and video instructions for each task while also allowing the operator to navigate between the teaching steps and control the video playback using a bare hands natural interaction interface that is projected into the workspace. Moreover, for helping the operator during the final validation and inspection phase, the system projects the expected 3D outline of the final product. The proposed teaching system was tested with the assembly of a starter motor and proved to be more intuitive than reading the traditional user manuals. This proof of concept use case served to validate the fundamental technologies and approaches that were proposed to achieve an intuitive and accurate augmented reality teaching application. Among the main challenges were the proper modeling and calibration of the sensing and projection hardware along with the 6 DoF pose estimation of objects for achieving precise overlap between the 3D rendered content and the physical world. On the other hand, the conceptualization of the information flow and how it can be conveyed on-demand to the operator was also of critical importance for ensuring a smooth and intuitive experience for the operator. © 2019 IEEE.

Abstract
We face a technology growth period that promotes STEM (Science, Technology, Engineering and Mathematics) as basic set of competences in diversified professional backgrounds. However, the process of teaching this areas is complex and abstract. We propose using game-based learning (GBL) for increased engagement and efficacy. More specifically, we use pervasive games as the drive of the learning process, promoting challenges in the context of the learner. To develop pervasive games, we require mobile devices (for location-based games) and a set of functionalities regarding location, time, and context of the user. In this article, we present the design of a mobile app to implement pervasive games. The perks of the mobile devices will be used to get unique and engaging challenges, to stimulate learning. Therefore, the learning process will become more enjoyable, and it will accomplish the goal of learning "anytime anywhere". This work sets upon previous work developed in the H2020 BEACONING project and the mobile app presented will allow other developers to create pervasive games for distinct areas of learning in a more engaging and effective way.

Abstract
Augmented reality has seen a fast-growing gain of interest in the last few decades. Due to technological advances, smartphones are now devices that allow to experience augmented reality systems, anytime and anywhere. Although its emerging success among users, some problems AR have been reported inhibiting its full acceptance in our digital society. The aim of this paper is to present a study about techniques to implement augmented reality systems in the cultural heritage context, including a prototype to test the technology which, based on physical objects that belong to the landscape, present an effective and accurate augmented reality approach, overlaying 3D virtual models aligned over the real images, using a smartphone's camera.

Abstract
The use of augmented reality has a great potential applied to several areas, in particular, for cultural heritage context where it became possible to display, in loco, virtual elements which complement the user's real scenario. Due to technological advances, differentiated ways of experience this technology has been explored, providing to common user, the access to this technology, until recently, quite limited, especially, in public locations. This article presents a work which includes implementation and evaluation of distinct applications of augmented reality - using smartphones - based on different techniques and tools. The evaluation intends to identify a solution to be implemented in a cultural heritage context, namely, the ruins of the Museu Monografico de Conimbriga
