Connected home technologies, such as smart thermostats, lightbulbs, and door locks, have great potential to support independent activity performance among people aging with mobility disabilities. However, these devices often require technology expertise to use, set up, and maintain.  We explored how augmented reality, virtual reality, and telepresence tools can be used to enhance adoption and acceptance of connected home technologies among people aging with mobility disabilities. Through our prototyping studies with users, we found that telepresence systems, can be particularly useful to support remote technology troubleshooting. We developed a set-up to optimize remote troubleshooting via videoconferencing with features like additional camera views and on-screen annotations. We also identified limitations in using various Telepresence platforms (e.g., Zoom, Facetime) for remote troubleshooting and developed design recommendations to improve their accessibility and utility.
