ARTECH 2019: 9th International Conference on Digital and Interactive Arts, Braga, Portugal, October 23-25, 2019

Abstract
The main goal of the conference is to promote the interest in the current digital culture and its intersection with art and technology as an important research field, and also to create a common space for discussion and exchange of new experiences. It seeks to foster greater understanding about digital arts and culture across a wide spectrum of cultural, disciplinary, and professional practices. To this end, many scholars, teachers, researchers, artists, comput-er professionals, and others who are working within the broadly defined areas of digital arts, culture and education across the world, submitted their innovative work to the conference. © 2019 ACM.

Authoring Game-Based Learning Activities that are Manageable by Teachers

Authors
Cardoso, P; Morgado, L; Coelho, A;

Publication
ERCIM NEWS

Abstract
The great ambition of using games as the cornerstone of education is hindered by its associated teaching workload. The BEACONING project developed a framework based on an authoring tool for gamified lesson paths, which has been rolled-out in large scale across Europe. It includes stages for planning game-based educational activities, plus their deployment, monitoring, and assessment.

CHI PLAY'19: EXTENDED ABSTRACTS OF THE ANNUAL SYMPOSIUM ON COMPUTER-HUMAN INTERACTION IN PLAY

Abstract
To contribute in filling in the gap regarding experiences targeted at and evaluated by teenagers in museums, we involved 78 teenagers aged 16-19 to test three different gamified tours developed by cultural heritage professionals from the Natural History Museum of Funchal, Portugal. The digital tours can be described as follows: 1) expositive - through which teens become aware of a scientific library in the museum; 2) gastronomic - teens are exposed to curiosities and recipes regarding a selection of marine species exhibited in the museum; 3) digital manipulation manipulated characters (image and voice) guide the visitor through videos of the marine species in their natural habitats. We report on measuring the teenagers' overall experience with each of the prototypes, particularly their engagement with the exhibition, the usefulness and usability of the prototypes, as well as their feelings and emotions at the end of each tour. We report on lessons learned from the evaluation of these prototypes as well as which approaches and mechanics engaged the teens the most.

ENERGY AND BUILDINGS

Abstract
Office buildings consume a significant amount of energy that can be reduced through behavioral change. Gamification offers the means to influence the energy consumption related to the activities of the office users. This paper presents a new mobile gamification platform to foster the adoption of energy efficient behaviors in office buildings. The gamification platform is a mobile application with multiple types of dashboards, such as (1) an information dashboard to increase the awareness of the users about their energy consumption and footprint, (2) a gaming dashboard to engage users in real-time energy efficiency competitions, (3) a leaderboard to promote peer competition and comparison, and (4) a message dashboard to send tailor-made messages about energy efficiency opportunities. The engagement and gamification strategies embedded in these dashboards exploit economic, environmental, and social motivations to stimulate office users to adopt energy efficient behaviors without compromising their comfort and autonomy levels. The gamification platform was demonstrated in an office building environment. The results suggest electricity savings of 20%. © 2020 Elsevier B.V.

Age and level of education impact on expectancy and perceived similarity between virtual and real touristic environments

PROCEEDINGS OF THE 2019 INTERNATIONAL CONFERENCE ON GRAPHICS AND INTERACTION (ICGI 2019)

Abstract
This paper focuses on the combination of 360-degree video and virtual reality for improving the touristic experience. Three scenarios were considered in this study: two 360-degree video visualizations, each one related to different touristic places, both presented in an immersive way, followed by an actual visit to those places. By comparing these situations, it was intended to determine the degree of perceived similarity between the virtual and the corresponding real sites, and to analyze if the users' expectancy was fulfilled. This research comprised a qualitative analysis using data collection based on questionnaires, which were applied to a sample consisted of 45 participants. The independent variables of the study were the participants' age and level of education. The results show no statistically significant impact between the two independent variables (users' age and level of education) and perceived similarity and users' expectancy. Our findings suggest that virtual tourism can act as an efficient promotion tool, considering that users' perceived destination image is not compromised regarding their age or level of education.

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.
