Privacy Cards for Surfacing Mental Models and Exploring Privacy Concerns: A Case Study of Voice-First Ambient Interfaces with Older Adults

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. Using Privacy 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 with Privacy Cards revealed nuanced issues, resulting in various implications for future research and design.

Black Older Adults' Perception of Using Voice Assistants to Enact a Medical Recovery Curriculum

The use of interactive voice assistants (IVAs) in healthcare provides an avenue to address diverse health needs, such as gaps in the medical recovery period for older adult patients who have recently experienced serious illness. By using a voice-assisted medical recovery curriculum, discharged patients can receive ongoing support as they recover. However, there exist significant medical and technology disparities among older adults, particularly among Black older adults. We recruited 26 Black older adults to participate in the design process of an IVA-enacted medical recovery curriculum by providing feedback during the early stages of design. Lack of cultural relevancy, accountability, privacy concerns, and stigmas associated with aging and disability made participants reluctant to engage with the technology unless in a position of extreme need. This study underscored the need for Black cultural representation, whether it regarded the IVA's accent, the types of media featured, or race-specific medical advice, and the need for strategies to address participants' concerns and stigmas. Participants saw the value in the curriculum for those who did not have caregivers and deliberated about the trade-offs the technology presented. We discuss tensions surrounding inclusion and representation and conclude by showing how we enacted the lessons from this study in future design plans.

Look at Me When I Talk to You: A Video Dataset to Enable Voice Assistants to Recognize Errors

People interacting with voice assistants are often frustrated by voice assistants' frequent errors and inability to respond to backchannel cues. We introduce an open-source video dataset of 21 participants' interactions with a voice assistant, and explore the possibility of using this dataset to enable automatic error recognition to inform self-repair. The dataset includes clipped and labeled videos of participants' faces during free-form interactions with the voice assistant from the smart speaker's perspective. To validate our dataset, we emulated a machine learning classifier by asking crowdsourced workers to recognize voice assistant errors from watching soundless video clips of participants' reactions. We found trends suggesting it is possible to determine the voice assistant's performance from a participant's facial reaction alone. This work posits elicited datasets of interactive responses as a key step towards improving error recognition for repair for voice assistants in a wide variety of applications.
