Are Virtual Reality Serious Video Games More Effective Than Web Video Games?

Education, Video Games, Virtual Reality

Virtual reality is widely used for many educational purposes. However, despite the increasing trend in the use of this technology, it is not yet clear whether it is more effective for learning than other technologies, such as traditional computer video games. This article presents a serious video game to learn Scrum, a methodology widely used in the software industry. The game is available in mobile virtual reality and Web (using WebGL) formats. Both versions of the game are compared in terms of knowledge acquisition and motivation enhancement through a robust empirical study involving 289 students and instruments, such as prepost tests and a questionnaire. The obtained results suggest that both formats of the game are useful for acquiring knowledge and promoting aspects, such as fun, motivation, and engagement. The results also suggest, strikingly, that there is no difference in terms of learning effectiveness between the two versions of the game.

Learning and motivational impact of using a virtual reality serious video game to learn scrum

Education, Virtual Reality

Today, there is a great variety of learning techniques and methodologies: traditional lectures, role-plays, group dynamics, project-based learning, simulations, educational games, and so on. Regarding technology-enhanced learning, the educational usage of virtual reality is innovative and the initiatives carried out suggest that this technology is an appealing medium for young people that facilitates an active and effective teaching. On the other hand, agile methodologies are widely spread across the IT industry and it is necessary to look for the best techniques to learn them in the most appropriate way. This contribution presents a virtual reality serious video game, named ScrumVR, which aims to teach the key aspects of the most widespread agile methodology for software development: Scrum. To do so, this video game tries to gets players closer to their first weeks of work within a Scrum team. The empirical results, gathered through a case study conducted with 78 software engineering students and supported by instruments, such as prepost tests and questionnaires, indicate that ScrumVR facilitates the learning of the roles, meetings, artifacts, and practices employed in Scrum, and contributes to enhance student’s motivation and the whole learning experience.

A comparison of the usefulness of game-based learning and video-based learning for teaching software engineering in online environments

Education, Video Games

Despite prior research has shown several benefits of game-based and video-based learning and has compared these methodologies versus traditional instruction, little work has been done to compare their usefulness, especially in online education settings. This paper examines and compares the usefulness of game-based learning using educational video games and video-based learning for teaching software engineering in online environments. The design of this research is quasi-experimental, involving a control and an experimental group. A total of 193 software engineering students participated in this research, 45 in the control group and 148 in the experimental group. Both groups took a lesson about software design, but the students in the control group learned through online video-based learning, whereas their counterparts in the experimental group learned through online game-based learning. A survey was used to collect students’ perceptions and pre- and post-tests were used to measure acquired knowledge. The results indicate that both learning methodologies were found to be beneficial for student learning and that online game-based learning outperformed online video-based learning in terms of students’ perceptions.

Virtual Reality Presence in Partially Non-Euclidean Environments

Computer Graphcis, Video Games, Virtual Reality

Currently, virtual reality is limited by a physical workspace if the user walks indefinitely inside its virtual world. Therefore, it is necessary to find solutions to this limitation. A possible solution could be to reuse this workspace by overlapping different parts of the virtual space. This can be achieved through the use of imperceptible portals that connect different points in the virtual environment. Thanks to these portals it is possible to create a momentary break in the conventional Euclidean geometry displaying parts of the virtual world that are farther away than usual. Although this kind of effect has been seen in conventional games, its application to virtual environments has some technical implications. One of the most important technical characteristics to be evaluated is the presence, which could be affected by this type of visual effect. For this reason, a validation of the effect has been carried out by quantitatively analyzing the perceptual presence and conducting qualitative interviews with users. The results did not show an overall impact on presence, and users were excited to experience this type of visual effect inside the virtual world. Finally, this paper shows everything learned in this development and is discussed from a perceptual design point of view, opening the possibility of new studies associated with this visual effect applied to the virtual world.

Examining and Comparing the Effectiveness of Virtual Reality Serious Games and LEGO Serious Play for Learning Scrum

Education, Virtual Reality

Significant research work has been undertaken related to the game-based learning approach over the last years. However, a closer look at this work reveals that further research is needed to examine some types of game-based learning approaches such as virtual reality serious games and LEGO Serious Play. This article examines and compares the effectiveness for learning Scrum and related agile practices of a serious game based on virtual reality and a learning activity based on the LEGO Serious Play methodology. The presented study used a quasi-experimental design with two groups, pre- and post-tests, and a perceptions questionnaire. The sample was composed of 59 software engineering students, 22 of which belonged to group A, while the other 37 were part of group B. The students in group A played the virtual reality serious game, whereas the students in group B conducted the LEGO Serious Play activity. The results show that both game-based learning approaches were effective for learning Scrum and related agile practices in terms of learning performance and motivation, but they also show that the students who played the virtual reality serious game outperformed their peers from the other group in terms of learning performance.

Long short-term memory prediction of user’s locomotion in virtual reality

Artificial Intelligence, Virtual Reality

Nowadays, there is still a challenge in virtual reality to obtain an accurate displacement prediction of the user. This could be a future key element to apply in the so-called redirected walking methods. Meanwhile, deep learning provides us with new tools to reach greater achievements in this type of prediction. Specifically, long short-term memory recurrent neural networks obtained promising results recently. This gives us clues to continue researching in this line to predict virtual reality user’s displacement. This manuscript focuses on the collection of positional data and a subsequent new way to train a deep learning model to obtain more accurate predictions. The data were collected with 44 participants and it has been analyzed with different existing prediction algorithms. The best results were obtained with a new idea, the use of rotation quaternions and the three dimensions to train the previously existing models. The authors strongly believe that there is still much room for improvement in this research area by means of the usage of new deep learning models.

Design of a serious games to improve resilience skills in youngsters

Education, Video Games

Nowadays, extremist ideologies are increasing their presence around the world, while having an impact on different social fields, such as politics, religion, or even sports. Youngsters are especially vulnerable to this type of ideologies, as they are still conforming to their own ideals, which in turn represents a problem on their moral and ethical development. While today there exist many programs and projects which focus on confronting this problem, most of them focused in psychological protective factors, it is still necessary to adapt these methodologies to the new characteristics of society and attract the interest of young people. In this research, we present the design and pilot testing of YoungRes, a serious game focused on promoting resilience skills. This paper describes the theoretical foundations of the intervention, its development as a serious game, and its validation in pilot testing made by educators, psychologists, and psycho-pedagogues. The pilot testing is conducted through the trial of educators of the first two video game sessions. After that, they reported feedback on their opinions about the game, together with suggestions and measures about the impact it could have for educational purposes.

Multi-technique redirected walking method

Virtual Reality

The Room-Scale locomotion method is one of the most realistic locomotion methods used in virtual reality technologies. This is due to the natural interaction obtained through the tracking of its controllers and the head-mounted display with six degrees of freedom. However, its mapping by position between the physical and the virtual world limits the user’s movement to the physical workspace provided by the corresponding device. Redirected Walking methods use gain algorithms that add modifications to the virtual movement of the user, optimizing the virtual workspace in the same physical workspace. In this article, we develop a new Redirected Walking method, which combines the modification of three gain algorithms (curvature gain, rotation gain, and translation gain), a new algorithm (deviation gain), a path predictive method of the user’s locomotion, a proportional distance to the center function, and a user direction smoothing function that softens the effect of the algorithms. Complementing the new method, we offer an automatic calibration system that allows the user to use our method in a personalized way.

Virtual reality application for fostering interest in art

Education, Virtual Reality

There is concern within the cultural community about the decreasing number of people, especially young people, visiting museums and cultural institutions. To fight this trend, new ways of accessing art are needed. We believe that technologies like virtual reality can greatly foster the relationship between users and works of art. In this article, we present an elaborated virtual reality experience, ImmersArt, whose aim is to take users literally inside a work of art and the creative universe of its creator. The motivational impact of this tool was empirically analyzed and compared with other formats for experiencing art such as illustrated books and audiovisual presentations. The study suggests that young people are more motivated to study artwork when using virtual reality.
