Situational Limitations (Situational Impairments, Contextual Limitations)
Temporary constraints on a user's ability to interact with technology due to their environment, device, or circumstances rather than a permanent disability. Examples include using a mobile phone in br…
Situational Trust (Situational Trust in Automation)
A context-sensitive form of trust in an automated system that varies moment-to-moment based on perceived system performance, environment, and the user's own capacity to intervene. Unlike dispositional…
