Adaptive User Interface Design In Multimedia Courseware

The use of multimedia courseware in teaching and learning environment has contributed and reformed conventional education sector into a new dimension. The courseware used as computer assisted instruction (CAI) and computer assisted learning (CAL) tools gave positive impact toward the understanding and creative thinking for the student. Hence, lots of courseware being developed but only a small number of courseware emphasis on user interface design that suitable for the user interests and preferences. As a result, many courseware developed is failed and not suitable to be use in school. Thus, this research integrates user adaptively technique with storytelling approach in developing multimedia courseware based on diversity of user interface approach. User adaptively techniques allow the user-system interaction to be adapted to different user and different usage situation, while storytelling approach used to attract user toward the content delivered. The courseware could also be used as CAI-CAL in religious subject in Malaysia primary school. Targeted users are Malaysian student in year 5 and 6 within the age of 11 to 12 years old. The courseware developed based on modified instructional model and consists of four main modules. Based on user adaptively technique, the courseware gives a few option for the user according to their preferences and then by giving a simple activities, it identifies the type of user either graphic or interactivity person. The framework design and instructional model employed in developing the courseware could generate new perspective in multimedia courseware production. Whereas the interactive religious content incorporated in the prototype could attract the interest of the student to learn the subject matter in order to produce excellence student with good attitude for the sake of the country in developing a knowledge and success society

Multimedia Design And Development In Mathematics Learning Courseware For Preschool Education

Multimedia technology has reform the current education system and is successfully implemented for its advantages and capabilities. This paper is about the multimedia implementation in developing learning courseware to introduce basic Mathematics knowledge for preschool children within the age of 4 to 6 years old. The objectives are to design an ID Model for Mathematics Preschool and to develop multimedia courseware used as CAI and CAL tools. The constructivism theory incorporated in the form of thematic and contextual approach used to allow learners construct their own knowledge and relate it with their daily life. The courseware prototype discussed consists of three main modules including Knowing Numbers Module, Writing Numbers Module and Activities Module. The combination of multimedia elements such as graphic and animation facilitate learners to experience mathematics. The courseware is expected to act as a catalyst for the implementation of Information and Communication Technology in preschool education in Malaysia.

Image segmentation for lung region in chest X-ray images using edge detection and morphology

Studies of medical image segmentation have long been done as a mean to distinguish object region from one to another for further image analysis. The segmentation of lung region in chest X-ray (CXR) based on object edge detection is one of the popular method applied. Early edge detection algorithms like Sobel, Prewitt and Laplacian have been used to segment the lung however, none of them can successfully generate a truly satisfied segmentation output. The reason for this fail is because they are high pass filter that is sensitive to image noise. Hence, the requirement for better edge detection algorithm that can cope with reasonable lower and upper threshold value for image noise like canny edge should be highlighted. Moreover, combining this algorithm with morphology method (dilation and erosion) will produce better outcome. Therefore, this paper has proposed method for segmenting lung region in CXR images using canny edge filter and morphology. Although the filter can detect the lung edge, unfortunately, the final edges lines produce are still unsatisfied. To solve the problem, Euler number method is applied to extract the lung region before executing the edge detection using the filter. The implementation produced convincing result as most of the segmented image is almost similar to the ground truth image.

Storytelling Approach In Multimedia Courseware: An Introduction To Science For Preschool Education

Education plays an important role in human knowledge and development. Due to the rapid development of current science and technology, this paper discusses about the used of storytelling approach in the development of an interactive multimedia courseware as an introduction to science for preschool education. Developing an interactive multimedia courseware with storytelling approach promotes learning process become more exciting and the knowledge could be delivered and acknowledged easier. The purpose of the courseware is to act as CAI and CAL tool for 5 to 6 years old preschool children in order to gain their interest in science subject; to nurture good values; to encourage and improve their reading abilities. The courseware is developed based on ADDIE methodology and used Macromedia Director as the main platform. The development started by designing the courseware conceptual model as one of the objective. The courseware is delivered in English and incorporated adventure module, option module and game module. The storytelling approach used in creating the adventure module, which display a story about a seed that fly away from its origin, grows and becomes a tree with the help of water from the rain and light from the sun in a new place where its landing. It is hoped that the development of the courseware could attract students toward science education. Hence, the courseware could help in promoting and enhancing preschool education specifically in Malaysia in promoting the development of excellent individual in a knowledge society

Multimedia Adventure Game As Edutainment Application

Computer game is one of the popular products among children. This product could generate an advantage and disadvantage up to the suitability of the content to the user. This paper discusses a development of adventure-game prototype that incorporated moral topic based on Malaysian curriculum for year 1 till year 6. By using the game approach, the prototype could attract children to be interested in learning the content. The prototype is developed based on rapid prototyping model integrating with steps of game development. The prototype consists of 6 scenes to make learning process become easier and interesting. User explores each scene to complete the game. Wintermute is used as the adventure-game engine that could be run in windows platform. With this adventure-game prototype, it is hoped that the student has another option in learning moral topic in such an interesting and interactive way of learning environment

The spatial relation features for describing objects relationships within image

Spatial features has gained attention in CBIR researches as a mean to represent image properties. These features, presented via Spatial Relation Features (SRF) such left, right, on and in can provide fine queries to locate object location as well as its relation with other object within an image. Although spatial features play an important, yet, there is still less effort done to collect them in proper manner which yield difficulties to use them for spatial-based image processing research. In order to overcome this lack, we presented our library research work in finding the SRF that have been used in computer science research for describing objects spatial relationships within image. Our work managed to produce collection of SRF found in prior literatures which are later listed and described in proper tables. Apart from that, we also described categories that are used to group these SRF in fine arrangement based on their usage. After updated the SRF list, we manage to derive 24 set of SRF recorded under three categories namely topology, orientation and metric.
