Remote testing considerations

Remote testing brings cameras into participants' homes, creating privacy challenges that in-person lab testing avoids. Background visibility in video calls can reveal personal details participants didn't intend to share like family photos, religious items, financial documents on desks, or household conditions they consider private. Offer virtual backgrounds or blur options before sessions start and explicitly tell participants they can enable these features anytime. Some participants may not realize these controls exist or feel awkward asking to use them mid-session.

Household members appearing in frame creates consent complications because they never agreed to participate in research or be recorded. A child walking past during a parent's usability session, a partner visible in a mirror, or roommates overhearing the conversation all become inadvertent research participants without proper consent. Give participants permission to pause video or mute audio when others enter their space, and build this option into your session script so they know it's acceptable. Consider audio-only sessions when video isn't essential for the research goals.

Device access permissions for remote testing tools can be more invasive than participants realize. Screen sharing might capture notifications containing sensitive messages, password managers auto-filling credentials, or browser history revealing private interests. Ask participants to close unnecessary applications, turn on "do not disturb" mode, and use browser guest profiles before testing begins. For software installations, use web-based testing tools that don't require downloads, or provide clear uninstallation instructions immediately after the session concludes.
