Abstract
A system is provided to automatically control input permission when multi users and/or software agents interact with a single, shared application in a window-based computing environment, and to indicate to all users which user or software agent currently is providing input or seeking input permission. The system operates by providing each user and agent with a specialized cursor icon that is used for displaying input-permission status and for requesting and relinquishing input-permission. Cursors have three modes with distinct appearances indicating whether the corresponding user or agent has, does not have, or desires input permission. Cursors are replicated on all displays, so that all users can at all times easily see who has or desires input permission. Users interact with the input-permission system by moving and clicking their mouse. Software agents achieve the same effects by sending control requests directly to a software interface provided as part of the invention. In one embodiment, each user and agent also has an assigned Home Window, which is used for identification and to compose and display text messages.
