Canada is prioritizing digital healthcare solutions to help address staffing shortages, access inequities, and the needs of an aging population where remote healthcare can be critical.
We interviewed 21 Canadians aged 65 to 87 with chronic health conditions about remote healthcare technology. They were interested in AI features but had concerns about safety and privacy. While they recognized that AI integration is inevitable, they felt powerless to avoid AI-driven solutions when seeking care.

To manage security and privacy threats effectively, users need to perceive relevant information. However, accessibility barriers prevent users with visual disabilities from accessing this information, which can lead to misinterpretations of their security and privacy.
We studied how these users protect their online security by observing their interactions with Gmail, Amazon, and a phishing site mimicking CNIB. We identified serious usability issues and outlined four states of security and privacy experienced during sensitive tasks.

Embodied cognition posits that understanding is closely linked to the environment and physical senses. We explored a new method to enhance security awareness through thermal notifications.
We present our system, NoViz-Thermal, and evaluate its effectiveness in communicating TLS certificate security. We identified accessibility and usability issues but believe that thermal stimulation can boost users’ confidence in making security assessments.

Usable security and web accessibility are often treated as separate issues. Existing research does not adequately address how users with vision loss secure their online experiences.
We created heuristics that merge both fields and evaluated ten websites, uncovering multiple issues that prevent users from following standard security advice.
