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.
This article presents an evaluation of 2D Animation of Learning Numbers and Letters for Children withVerbal Apraxia. The developed application provides some knowledge and encourage children with verbal apraxia to learn and know about numbers and letters. An experimental testing was conducted to evaluate the usability of the developed application, aimed as a therapy for the children who suffer this apraxia across all age. Five important evaluation components such as learnability, usability, accessibility, functionality, and effectiveness were included in this testing to investigate the user engagement and satisfaction of the proposed medical and educational learning system. Online questionnaires were distributed as a method to collect user testing outputs. A total of 33 respondents from multimedia designers, practitioners, psychologists, and parents were involved in this survey. The results of the testing indicate that majority of respondents are satisfied with the outcomes of the 2D animation video. The results presented may facilitate improvements in the teaching syllabus for students with speech and language disorder and produce a great visual animation treatment to the users.
Verbal Apraxia, also called Apraxia of Speech (AOS) is a speech sound condition that affects a person’s ability to translate conscious speech goals into motor plans, resulting in limited and difficult communication. This article presents an investigation on the designing of a 2D animation and its use as a therapy for Verbal Apraxia. This paper aims to investigate animation principles and to design and develop an animation video as a therapeutic solution. The expected outcome of this paper is a comprehensive analysis of the cognitive training in verbal therapy while focusing on spreading awareness of verbal apraxia towards society. In conclusion, this animation video runs successfully and meets all the objectives completely. Therefore, this proposed 2D animation is expected to contribute as a teaching syllabus for special needs schools and produce great usability for the users.
This article presents an investigation on the usability testing of Diabetic Retinopathy Consultation System (DRCS) development. DRCS is an interactive medical web-based consultation system for diabetic retinopathy screening with the features of image processing and image editing. The expected outcome of this paper is a comprehensive analysis of the web usability towards the development of a novel consultation system for diabetic retinopathy screening. Seven important usability evaluation components were included in this testing in order to investigate the user engagement and satisfaction of the proposed medical consultation system. Online questionnaires were distributed as a method to collect user testing outputs. A total of 27 respondents from the health clinics were involved in this survey. According to the outcomes of the online survey, the majority of respondents are satisfied with the outcomes of the DRCS. In conclusion, the online findings depict that the DRCS is highly functional, as required by the target users to assist consultation among medical doctors on diabetic retinopathy screening. This system is expected to contribute to diabetic retinopathy screening management and produce a great usability to the users.
