The virtual playground: an educational virtual reality environment for evaluating interactivity and conceptual learning

The research presented in this paper aims at investigating user interaction in immersive virtual learning environments (VLEs), focusing on the role and the effect of interactivity on conceptual learning. The goal has been to examine if the learning of young users improves through interacting in (i.e. exploring, reacting to, and acting upon) an immersive virtual environment (VE) compared to non interactive or non-immersive environments. Empirical work was carried out with more than 55 primary school students between the ages of 8 and 12, in different between-group experiments: an exploratory study, a pilot study, and a large-scale experiment. The latter was conducted in a virtual environment designed to simulate a playground. In this ‘Virtual Playground’, each participant was asked to complete a set of tasks designed to address arithmetical ‘fractions’ problems. Three different conditions, two experimental virtual reality (VR) conditions and a non-VR condition, that varied the levels of activity and interactivity, were designed to evaluate how children accomplish the various tasks. Pre-tests, post-tests, interviews, video, audio, and log files were collected for each participant, and analyzed both quantitatively and qualitatively. This paper presents a selection of case studies extracted from the qualitative analysis, which illustrate the variety of approaches taken by children in the VEs in response to visual cues and system feedback. Results suggest that the fully interactive VE aided children in problem solving but did not provide as strong evidence of conceptual change as expected; rather, it was the passive VR environment, where activity was guided by a virtual robot, that seemed to support student reflection and recall, leading to indications of conceptual change

Interactive Cultural Experiences using Virtual Identities

People create meaning through narratives or stories. Every culture has stories that are passed along from generation to generation. Culture influences our perspectives, values and behaviour. The story metaphor has been used in Multimedia and Virtual Environments to create interactive stories. Interactive stories enable users to interactively explore the story world and to be actively involved in the outcome of the story. Virtual environments are much richer in terms of freedom of navigation and ease of interaction. Projection-based systems in particular, don’t bind the user to a predefined path and enables the user to have a hands-on experience through immersion and interaction with the virtual world. Our approach for authoring interactive stories in virtual cultural environments allows the creation of several virtual identities, through whose eyes the user perceives the virtual world. Each identity is empowered with knowledge about itself and its perception about and embodiment in the virtual world. This approach allows free interaction and navigation that is appropriate for the specific virtual identity in the culture that is being experienced. This enables the user to experience the culture from many different angles and to get a true reflection and cultural experience

Using A Digital Planetarium For Teaching Seasons To Undergraduates

Computer-generated simulations and visualizations in digital planetariums have the potential to bridge the comprehension gap in astronomy education. Concepts involving three-dimensional spatial relationships can be difficult for the layperson to understand, since much of the traditional teaching materials used in astronomy education remain two-dimensional in nature. We study the student performance after viewing visualizations in an immersive theater and in non-immersive classrooms for the topic of seasons in an introductory undergraduate astronomy course. Using weekly multiple-choice quizzes to gauge student learning, comparison of curriculum tests taken immediately after instruction and pre-instruction quizzes show a significant difference in the results of students who viewed visualizations in the planetarium versus their counterparts who viewed non-immersive content in their classrooms, and those in the control group that saw no visualizations whatsoever. These results suggest that the immersive visuals help by freeing up cognitive resources that can be devoted to learning, while visualizations shown in the classroom may be an intrinsically inferior experience for students

Spontaneous Communities of Learning: Cooperative Learning Ecosystems Surrounding Virtual Worlds

This thesis is the culmination of a five year research project exploring online gamers and the cultures they engage with, both virtually in the many massively multiplayer games and virtual worlds online, and in the physical spaces they inhabit in various play spaces around the world. The primary research questions concerned social learning in such spaces, i.e. how do players learn from one another what they need to be successful, and what are the associated norms and practices for doing so? What sorts of peripheral skills are gained, and are they applicable to physical world contexts? Finally, what does participation in such spaces mean for individuals who may have lacked other mechanisms for social learning, and what impacts might such findings have on existing educational structures? I anticipate that this thesis will generate as many questions as it will answer, and I hope, that as a snapshot of a gaming culture in time, will be looked upon as a monograph in the classic ethnographic tradition

Virtual Reality

At present, the virtual reality has impact on information organization and management and even changes design principle of information systems, which will make it adapt to application requirements. The book aims to provide a broader perspective of virtual reality on development and application. First part of the book is named as "virtual reality visualization and vision" and includes new developments in virtual reality visualization of 3D scenarios, virtual reality and vision, high fidelity immersive virtual reality included tracking, rendering and display subsystems. The second part named as "virtual reality in robot technology" brings forth applications of virtual reality in remote rehabilitation robot-based rehabilitation evaluation method and multi-legged robot adaptive walking in unstructured terrains. The third part, named as "industrial and construction applications" is about the product design, space industry, building information modeling, construction and maintenance by virtual reality, and so on. And the last part, which is named as "culture and life of human" describes applications of culture life and multimedia-technology
