6.2-7 Shared Cursors

When multiple users must share a single cursor for interaction with the group-view display, features should be provided to manage access to the cursor and indicate current ownership.

Additional Information:
A method of managing access to the shared cursor should be provided to prevent conflict between potential users. In addition, a distinct coding method, consistent with Guideline 2.3.1-1, should be used to indicate that the cursor is in use and to identify of the user. The use of a shared cursor may be acceptable for group-view displays that are not frequently accessed by users. Frequent use of the cursor by multiple users may impose unacceptable delays to users who require immediate information. If the group-view display is used for communication/collaboration, the requirement to take turns may impede the natural flow of information from the group, but it may also provide an implicit way of managing the input of information. Thus, the disruptions to the flow of information should be balanced against the need for information to be presented in an orderly fashion.
