This study aims to develop a novel web-based decision support system for diabetic retinopathy screening and classification of eye fundus images for medical officers. The research delivers diabetic retinopathy information with a webbased environment according to the needs of the users. The proposed research also intends to evaluate the developed system usability to the target users. The complex characteristics of diabetic retinopathy signs contribute to the difficulty in detecting diabetic retinopathy. Therefore, professional and skilled retinal screeners are required to produce accurate diabetic retinopathy detection and diagnosis. The proposed system assists the communication and consultation among the medical experts in the hospital and the primary health cares located at the health clinics. The agile software development model is the methodology used for the development of this research project. The project collaborates with the Department of Ophthalmology, Hospital Melaka, Malaysia for the medical content expertise and testing. Representative medical officers from Hospital Melaka and all the public health clinics in Melaka were involved in the preliminary study and system testing. This research study consists of a web development producing an interactive web-based application of diabetic retinopathy consultation which comprises image processing and editing features as a core of the system. It is envisaged that this research project will contribute to the management of diabetic retinopathy screening among medical officers.

The objective of this study is to quantitatively incorporate user observation into usability evaluation of game interface design. In this study, an experiment was conducted to monitor and record users' behavior using built in video-cam. The experiment was done after the user play "A Garuda" game. All the character movement controlled by user were captured and recorded for comparative analysis. There were about 20 people involved as a subject for this experiment. The data from video recordings were coded with Noldus Observer XT in order to find usage patterns and thus to gather quantitative data for analyzing the GUI effectiveness, efficiency and satisfaction. The result of user's interaction towards the design of game's GUI able to give additional information for the game designer to develop a better responsive game toward its usability. The effect of user's control and emotion that can be seen from user's face will give the information needed to be considered in game development. Previous studies mostly focusing on evaluating the usability with performance measures by only looking at task results. Thus, at the end of this study, a method is proposed by incorporating user observation into usability evaluation of game design interfaces.

Poor wrist postures due to work requirements is one of the established risk factors contributing to the development of workrelated musculoskeletal disorders. This study systematically investigates the underlying hypothesis that identification and monitoring of poor wrist postures at work should be in the function of normalized wrist range-of-motion (ROM) instead of the traditional measurement of absolute wrist angle. This three-stage study looks into 1) existing issues related to current workplace wrist postural assessment methods, 2) development of a new architecture to assess and monitor wrist posture at work, and 3) qualitative review with ergonomics practitioners on the architecture. The first stage utilizes literature review and interview with ergonomics practitioners. Generative collaboration method was used to generate the architecture for the second stage. The third stage employs semi-structured interview with ergonomics practitioners. Several issues were identified in current wrist postural assessment methods. A conceptual architecture of the Wrist ROM System to assess and monitor wrist postural behaviors at workplace is proposed in this manuscript. The architecture was generally well received by the practitioners. The architecture provides the groundwork in the development of a technological system designed as a tool to analyze workplace wrist postural behaviors.
