A Conceptual Model of Interactive Persuasive Learning System for Elderly to Encourage Computer-Based Learning Process

Over the past few years, new and improved learning techniques and technologies have been introduced. Among them, interactive media holds a lot of potential in learning. This technology highly promotes self-directed and active learning approaches and has capabilities to foster the learning process. Furthermore, the emergence of persuasive technology increased the capability of the media features to be used in learning field within variety of ways. Persuasive technology is the attempts of several researchers and its founder to proof the power of persuasion through the computer technology in changing peoples behavior and attitude. Even though previous studies have highlighted the various features of interactive media contribute to learning, our preliminary study indicated that most of elderly prefers conventional learning approach over computer approach. It is evident that elderly choose the use of computer applications as their last resort in learning. In order to highlight an interactive media system with persuasion elements, this study attempt to propose a conceptual model of interactive persuasive learning system for elderly that can be used in encouraging them to learn using computer-based learning tools. Thus this paper reviews the introduction of persuasive technology and interactive media. Then, we propose the conceptual model of interactive persuasive learning system for elderly that can be used in encouraging them to learn using computer-based learning tools. The proposed model will be helpful in designing and developing interactive media systems that can encourage and engage a learning process among elderly.

Online 3D Terrain Visualization: A Comparison of Three Different GIS Software

In recent times, the online 3D terrain visualization has created much interest in many applications such as land information system, military, environmental, tourism and mapping science. Many systems such as CityGML, Terraserver, Google Earth and Spaceye3D have successfully adopted this technology in their system for different applications. The aim of this paper is to compare the effectiveness of developing online 3D terrain visualization by using three popular GIS Software; R2V, Arc View 3.2 and Arc GIS 9.2. In this paper, we implement the system based on the Digital Elevation Model (DEM) and Triangulated Irregular Network (TIN) for the terrain data and then overlay with satellite image. Finally, the effectiveness of online 3D terrain rendering in terms of terrain visualization quality, file size, and loading time are made to compare the quality of the systems. The results help the developers on finding the right software to be used for their online 3D terrain visualization.

An effective visualization and comparison of online terrain draped with multi-sensor satellite images

The objective of this paper is to discuss the effectiveness of visualizing online 3D terrain draped with different satellite imageries. The topographic data of the study area were obtained from the contour maps of Universiti Putra Malaysia, Selangor, Malaysia. The high resolution satellite imageries used in this project involving QUICKBIRD (0.6xa0m resolution), IKONOS (1xa0m resolution), and SPOT5 (5xa0m resolution). R2V software was used for editing the contour data, whereas Arc GIS was used for overlaying the imageries over the 3D terrain data. Then the data were exported into Virtual Reality Markup Language to compare the effectiveness of different satellite imageries based on the data file size, imageries size, number of images tile, loading time during office hours (from 8 a.m. to 5 p.m.) and out of office hours (after 5 p.m.), frame rate per second, and visualization quality. The results revealed that IKONOS satellite imageries are better for an effective online 3D terrain visualization utilizing GIS data even though it has lower resolution compared to QUICKBIRD.

Virtual robot: virtual becomes reality

One of the benefits that education reaps from virtual reality (VR) is the ability to visualize, simulate and interact with virtual objects. This ability allows students to have a trial and error session before actually practicing on real objects. The article considers the idea of a virtual robot assisting students in learning. Instead of studying a physical robot in class, students can study a virtual robot on a computer at home prior to or even in the class itself. Students can immerse themselves in this digitized world and experience the sense of moving and becoming part of the robot system. This paper presents a methodology for the whole-robot 3D graphics design, integration between object modeling and VR, and the construction of real-time behavior and interactivity modification to accommodate changes in the virtual environment.
