    Gamification Mechanics for Playful Virtual Reality Authoring
    (The Eurographics Association, 2020) Naraghi-Taghi-Off, Ramtin; Horst, Robin; Dörner, Ralf; Biasotti, Silvia and Pintus, Ruggero and Berretti, Stefano
    An increasing number of companies, businesses and educational institutions are becoming familiar with the term gamification, which is about integrating game elements into a non-playful context. Gamification is becoming more important in various fields, such as e-learning, where a person needs to be motivated to be productive. The use of Virtual Reality (VR) is also being researched in various application areas. Authoring of VR content is a complex task that traditionally requires programming or design skills. However, there are authoring applications that do not require such skills but are still complex to use. In this paper, we explore how gamification concepts can be applied to VR authoring to help authors create VR experiences. Using an existing authoring tool for the concept of VR nuggets as an example, we investigate appropriate gamification mechanics to familiarize authors with the tool and motivate them to use it. The proposed concepts were implemented in a prototype and used in a user study. The study report shows that our participants were able to successfully use the gamified authoring prototype and that the participants felt motivated by various gamification aspects, especially visual rewards and story elements.

    Smart Modelling of Geologic Stratigraphy Concepts using Sketches
    (The Eurographics Association, 2020) Sousa, Mario Costa; Silva, Julio Daniel Machado; Silva, Clarissa Coda Marques Machado; Carvalho, Felipe Moura De; Judice, Sicilia; Rahman, Fazilatur; Jacquemyn, Carl; Pataki, Margaret E. H.; Hampson, Gary J.; Jackson, Matthew D.; Petrovskyy, Dmytro; Geiger, Sebastian; Biasotti, Silvia and Pintus, Ruggero and Berretti, Stefano
    Several applications of Earth Science require geologically valid interpretation and visualization of complex physical structures in data-poor subsurface environments. Hand-drawn sketches and illustrations are standard practices used by domain experts for conceptualizing their observations and interpretations. These conceptual geo-sketches provide rich visual references for exploring uncertainties and helping users formulate ideas, suggest possible solutions, and make critical decisions affecting the various stages in geoscience studies and modelling workflows. In this paper, we present a sketch-based interfaces and modelling (SBIM) approach for the rapid conceptual construction of stratigraphic surfaces, which are common to most geologic modelling scales, studies, and workflows. Our SBIM approach mirrors the way domain users produce geo-sketches and uses them to construct 3D geologic models, enforcing algorithmic rules to ensure geologically-sound stratigraphic relationships are generated, and supporting different scales of geology being observed and interpreted. Results are presented for two case studies demonstrating the flexibility and broad applicability of our rule-based SBIM approach for conceptual stratigraphy.
