Input/output linkage in a user interface management system

Abstract

The GRaphical INteraction System (GRINS) is described, which integrates an automation-based dialogue controller with a dynamic display model to provide a User Interface Management System. The linkage between the logical device interface and the graphical presentation of virtual devices is discussed. A display manager to support dynamic manipulations of hierarchically structure images is presented. Lastly a model of Display Objects whereby application-specific display objects can have computational constraints defined is described. The constraint system is equivalent to an attributed grammar and is evaluated using an incremental attribute flow algorithm.
