Shared Single Display Application : An Interactive Patterns Approach
Cheah WaiShiang,Edwin Mit,Alfian Abdul Halin 보안공학연구지원센터 2015 International Journal of Software Engineering and Vol.9 No.2
Interactive patterns are able to promote the notion of interaction in groupware application development. Hence, these patterns improve the students’ engagement and promote problem solving collectively. This paper reports on the usability of the interactive patterns in designing and developing a collaborative language application. With interactive patterns, we are able to design and develop two different interactive shared single display education applications. RimbaIlmu is an after school programme to allow students to learn Bahasa Malaysia during their free time. RICLAT is an authoring tool for collaborative presentations. The patterns are useful to enrich the interaction among both education applications. Also, it facilitates more effective communication among the group members and enriches the interaction for students based on the qualitative analysis.
Aerial Images Rectification Using Non-parametric Approach
Lee Hung Liew,Beng Yong Lee,Beng Yong Lee,WaiShiang Cheah 한국정보기술융합학회 2013 JoC Vol.4 No.2
Geometric distortions caused by different sources usually are accumulated and not present singly in a remotely sensed image. In addition, the effects of geometric distortions are found unequally in the entire image. Hence, aerial images should be rectified before proceed with subsequent images analysis. Control points and geometric transformation are the essential components in non-parametric approach. Barrel and perspective distortions are usually found in aerial images. This paper studies the deformation rate contributed by control points at different regions in an image before rectification according to different distribution patterns. Besides, this paper also discusses the appropriate geometric transformation through the concern of the expected distortions. Experiments are conducted using grid images and aerial images to investigate the effect of distributions of control points and the efficiency of global and local geometric transformations for aerial images rectification. It demonstrated that control points at different image regions have different deformation rates, control points distributed at image centre are less distorted and local transformation performs better in rectifying images with complex distortions.
