Prof Shvartzshnaider's co-authored a paper on "Privacy Cards: Surfacing mental models and exploring privacy concerns of voice-first ambient interface" that will appear in the proceedings of the conference on Human Factors in Computing Systems (CHI'26), a leading international conference on Human-Computer Interaction.
Cuadra A, Sabie S, Shvartzshnaider Y, Estrin D. Privacy Cards for Surfacing Mental Models and Exploring Privacy Concerns: A Case ¿ì²¥ÊÓƵ of Voice-First Ambient Interfaces with Older Adults. CHI ’26. 2026.
"We investigate the ethical and privacy implications of voice-first ambient interfaces (VFAIs) for aging in place through an in-depth engagement with five older adults. Our participants were in the process of becoming experienced VFAI users, and had used a VFAI-based design probe for health data reporting. We create and iteratively refine an interview protocol using Privacy Cards. We customize Privacy Cards by drawing on participants’ previous interviews and device usage logs. UsingP rivacy Cards we conduct interviews to surface their mental models, and explore their privacy concerns. We find insufficient mental models for proper consent. For example, participants did not know who could access their data, and experienced difficulty distinguishing built-in functionality from third-party apps. Participants initially expressed little worry about VFAI-related ethical concerns, but interviews withPrivacy Cards revealed nuanced issues, resulting in various implications for future research and design."
