Privacy Starts with UI: Privacy Patterns and Designer Perspectives in UI/UX Practice

In the study of Human-Computer Interaction, privacy is often seen as a core issue, and it has been explored directly in connection with User Interface (UI) and User Experience (UX) design.We systematically investigate the key considerations and factors for privacy in UI/UX, drawing upon the extant literature and 15 semi-structured interviews with experts working in the field.These insights lead to the synthesis of 14 primary design considerations for privacy in UI/UX, as well as 14 key factors under four main axes affecting privacy work therein.From these findings, we produce our main research artifact, a UI/UX Privacy Pattern Catalog, which we validate in a series of two interactive workshops and one online survey with UI/UX practitioners.Our work not only systematizes a field growing in both attention and importance, but it also provides an actionable and expertvalidated artifact to guide UI/UX designers in realizing privacypreserving UI/UX design.
