Inclusive Contactless Monitoring – Perspectives of Older Adults from Diverse Backgrounds (Preprint)
Bibliographic record
Abstract
<sec> <title>BACKGROUND</title> As Canada’s population ages, accessible tools for chronic health monitoring are increasingly needed. Traditional and contact-based devices pose barriers for underserved populations due to cost, maintenance, and usability. Contactless sensing technologies offer a promising alternative, but equitable development requires inclusive engagement and diverse data collection. </sec> <sec> <title>OBJECTIVE</title> This work aimed, firstly, to gather perspectives from culturally- and health-diverse seniors on innovative contactless vital-sign monitoring technology and, secondly, to build on a diverse dataset for developing and testing the contactless sensing software VitalSeer by the National Research Council of Canada. </sec> <sec> <title>METHODS</title> A mixed-methods study was conducted on 48 diverse and elderly adults across three sites. Participants were asked to respond to a questionnaire, which had closed and open-ended questions regarding their perspectives on contactless sensing technology. Video and reference vital sign data were collected from each participant using a portable system that was designed specifically for gathering controlled data. </sec> <sec> <title>RESULTS</title> We collected data from 48 (mean 70, SD 8 years), of which 98% expressed a positive perception of the usefulness of a contactless sensing system. We also identified 4 themes from the qualitative analysis of the open-ended questions: (1)Perceived Value – System potential and clinical relevance, (2)Ease of Use – Non-invasiveness and comfort, (3)Trust and Transparency – Data security and clarity of design, and (4)Inclusion and Improvement – Accessibility, functionality, and feature expansion. Finally, the collected data, 288 minutes of concurrent video and reference vital sign data, will be used to test and enhance contactless sensing software for diverse senior populations. </sec> <sec> <title>CONCLUSIONS</title> This work demonstrates and furthers the goal of inclusive medical device research and development. It highlights the potential for contactless sensing to be adopted to support independent living for older, diverse adults. Research is ongoing to adapt the technology for widespread adoption. </sec>

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
