Designing the Claims Reuse Library: Validating Classification Methods for Notification Systems

Abstract

We discuss our research into the development and testing of a notification system claims library for assisting designers in interface development. Our research focuses on achieving consistent values among multiple users when adding and searching claims. We discuss the methods used for redesigning the application, techniques used for testing, and reengineering goals for the Claims Library. This work extends previous efforts on design knowledge reuse in the HCI research community, as such our methods and techniques should be reusable by others. We designed the interface to the library for users entering claims, ensuring usability and understandability. Since we noted problems with a particular feature (the IRC input method) through an internal round of testing, we conducted a lab-based test to isolate specific breakdowns. Our results validated portions of claim classification indices, suggest key reengineering changes that should inform ongoing and future development of the claims library—of broad interest of notification systems developers
