A Prototype Development of a Mobile Schedule Viewer Integrating QR Code Technology and Decorator Design Pattern for Effective Dissemination of Class Schedules

Class schedules undergo continuous changes with each new release, making manual scheduling a complex task. To address this issue, this study proposes integrating a mobile application that enables students to promptly access their accurate class schedules. A prototype mobile schedule viewer was developed to identify and resolve conflicts arising from conflicting schedules. The study confirmed the functionality and stability of the spreadsheet application, as the mobile schedule viewer successfully employed the decorator design pattern and integrated QR code generator plugins. These plugins facilitated the extraction of existing schedule files from the University Integrated Information System (UIIS). The overall findings indicate that the applications are 95 percent complete in terms of degree of completeness (DOC) and boast a record level of accuracy (RLA) of 95 percent.
