RESUMEN
An effective screening test could significantly impact identification of developmental delays at an early age. However, many studies have shown that delay screenings still use text-based screening survey questionnaires. Unfortunately, the traditional text-based screening method tends to be fairly passive. In addition, the advantages of using an interactive system and animation have been shown to lead to positive effects on learning in medical research. Therefore, a multimedia screening system is necessary. This study constructs a system architecture to develop an e-screening system for child developmental delays. To validate the system after development, this study conducted an experiment and employed a questionnaire to survey users. Five experts and 120 subjects participated in the experiment. After the experiment, the results of the system evaluation revealed excellent agreement between the text-based and multimedia version of Taipei II. A total of 118 (98%) participants preferred the multimedia version or had no preference, and only 2 (2%) preferred the paper version. Regular text-based screening sometimes excludes those with low literacy and those whose native language is different from the text. In addition, text-based screening tools lose users' attention easily. The current study successfully developed a multimedia text-based screening system. Feedback from the participants showed that the e-screening system was well accepted and more easily accessible than the original. In this study, a child developmental delays e-screening system was developed. After the experiment, the subjects indicated that the developmental delay e-screening system increased their comprehension and kept them interested in the screening.

The Digital Accessible Information SYstem (DAISY) player is an assistive reading tool developed for use by persons with visual impairments. Certain problems have persisted in the operating procedure and interface of DAISY players, especially for their Chinese users. Therefore, the aim of this study was to redesign the DAISY player with increased usability features for use by native Chinese speakers. First, a User Centered Design (UCD) process was employed to analyze the development of the prototype. Next, operation procedures were reorganized according to GOMS (Goals, Operators, Methods, and Selection rules) methodology. Then the user interface was redesigned according to specific Universal Design (UD) principles. Following these revisions, an experiment involving four scenarios was conducted to compare the new prototype to other players, and it was tested by twelve visually impaired participants. Results indicate the prototype had the quickest operating times, the fewest number of operating errors, and the lowest mental workloads of all the compared players, significantly enhancing the prototype's usability. These findings have allowed us to generate suggestions for developing the next generation of DAISY players for people, especially for Chinese audience.
