Glossary » situational impairment
a difficulty accessing computers due to the context or situation one is in, as opposed to a physical impairment. Examples include noise, poor lighting, distractions, other tasks that require use of hands or eyes, and social constraints such as the inappropriateness of using devices with audio when attending a lecture. For instance, users who are driving are unable to effectively work with complex visual displays. Users in noisy situations (or quiet ones) may be unable to use audio or speech interfaces.
