On Inclusion: Video Analysis of Older Adult Interactions with a Multi-Modal Voice Assistant in a Public Setting
Open accessAbstract
Older adults around the world lack access to a wide range of potentially life-changing digital applications, services, and information that could be provided by voice assistants (such as Amazon’s Alexa, Google’s Assistant, or Apple’s Siri). However, older adults’ needs are underrepresented in the design of voice assistants. Because of this, we are missing opportunities for digital inclusion, and increasing risks of excluding older adults as these devices permeate public settings. In this work, we video record older adults (n=26) interacting with a multi-modal voice assistants while waiting in line at food pantries, and use Interaction Analysis to draw insights from these recordings. We find that by being agnostic to body language, audio-prosodic features, and other contextual factors, voice assistants fail to capture and react to some important aspects of interactions. We discuss design (e.g, interpreting users’ posture as a cue to wake the device when they are leaning towards the device) and research (e.g., surveillance trade-offs) implications, and argue for the use of multi-modal inputs with attention to privacy. Designing and training voice assistants to take in and appropriately respond to non-verbal cues may increase their inclusivity, helping them fulfill important needs of our aging population.

Older adults often find it challenging to remember commands associated with voice assistant features and skills, even simple wake words.
“they often find it challenging to remember commands associated with VA features and skills [49, 57]-even those as simple as a wake word [1, 15, 49].”
From Situated Understanding of Errors in Older Adults' Interactions with Voice Assistants: A Month-Long, In-Home Study (2026) · cites this paper as [15]
Section 4.1.1, “Overlooked by the machine” (page unavailable), reports that older participants frequently mispronounced, omitted, or misplaced the wake word. The paper supports difficulty using the wake word, but does not establish that the cause was difficulty remembering it or show a broader difficulty remembering commands for features and skills. (LLM, conf=0.84)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
