An augmented reality-based authoring tool for E-learning applications

In recent years, augmented reality technologies have been a subject of great interest among the scientific community. However, most studies have focused on hardware and software development without particular emphasis on the authoring phase. As a consequence, the authoring process of augmented reality applications is accomplished today through hard-coding of a specific application. This approach, however, requires operators. In the education applications, the hard-coding methods tend to be retained, despite remarkable technological developments in the industrial area. Textbooks are mainly used in educational systems and many educators are very passive about applying new materials. In this paper, we present an immersive authoring tool for education using augmented reality, where applications authorized by our tool interact with the user in order to increase the learner’s interest and reflect various desires of dynamic environment. Our authoring tool consists of a composing tool that can be used to create educational contents, a viewer that plays the content, and an engine to power the tool and viewer.

An Immersive Authoring Tool for Augmented Reality-Based E-Learning Applications

In recent years augmented reality technologies have been subject of great interest among the scientific community. However, most researches have focused on hardware and software development without particular interest on the authoring phase. As a consequence the authoring process of an augmented reality application is done today through hard-coding of a specific application. This approach however requires operators. In education application, old-fashioned ways are kept especially in educational system, although technological developments in industrial area are remarkable nowadays. Textbooks are mainly used in educational systems and many educators are very passive about applying new materials in use. So, traditional methods are still used these days. We present an immersive authoring tool using the augmented reality, which interacts with user in order to increase learners interest and reflect various desires that dynamic environment students have. It consists of composing tool that can be used to create educational contents, viewer that plays the contents and the engine which allows these what to happen.

Augmented Reality-Based Role-Playing Contents for Education

In recent years, augmented reality technologies have been a subject of great interest among the lots of community. In the education applications, old-fashioned materials are still used, despite remarkable technological developments in the industrial area. Textbooks are mainly used in educational systems and many educators are very passive about applying new materials. In this paper, we present an augmented reality system for education. Our system consists of an authoring tool that can be used to create educational contents, a viewer that plays those contents, and an engine to power the tool and viewer. Based on the system, we present three role-playing contents for increasing educational benefits.

An immersive e-learning system providing virtual experience

This paper introduces immersive e-learning system which provides vivid learning experience using augmented reality(AR) technology. This system gives illusion that participants feel as if they are in foreign environment by synthesizing images of participants, virtual environment, foreign-language speakers in real-time. Furthermore, surrounding virtual environment reacts to the behavior of each participant including student, local teacher, remote teacher. The system has been installed along with 10 scenarios at 14 public elementary schools and conducted during regular class time. This paper presents our motivations for the system development, a detailed design, and its contents.

Hybrid Camera Based Real-Time Human Body Segmentation for Virtual Reality E-learning System

This paper proposes hybrid camera based video segmentation approach of human body for virtual reality e-learning system. Color and IR(Infra-red rays) image are used for human body segmentation at the same time. Human foreground pixels are separated from background in color and IR image respectively. And two foreground pixels are integrated as final foreground result for better performance of human body segmentation. Good foreground human segmentation is useful for virtual reality e-learning system.
