Patterns for User Interface Adaptations: Towards Runtime Adaptations for Improving the Usability of Web Forms for Elderly Users

摘要

Websites and web applications that require user input via web forms can be a usability barrier for elderly users if not designed carefully. This issue is even compounded by a broad diversity of needs and preferences as observed in this group of users. In this paper, we report about a current study in which we prototypically implemented and empirically evaluated four exemplary patterns of user interface adaptation. These patterns allow for dynamic substitution and/or augmentation of user interface parts at runtime, with the goal of improving the individual usability for an elderly user in a specific use context. This approach could eventually lead to highly personalized web forms within GPII and URC enabled infrastructures.
