[5.8.5] Conventionally designates those details and objects that must be seen for the performance of a given activity, and includes the immediate background of the details or objects.

Note: The term visual task as used is a misnomer because it refers to the visual display itself and not the task of extracting information from it. In addition, the task of extracting information has to be differentiated from the overall task performed by the observer.
