Abstract
A method of providing efficient on-line and interactive application program utilization of an assortment of devices calling for different screen characteristics. An application programmer writes screen definitions for a particular device to be used. These definitions are stored exterior of the application program and are used to define the quantity, order, and placement of the application program's information on the screen. The application program provides services to generate and process each data element which can be presented. These services are used by a mapping system in conjunction with the screen definition to generate and process a device dependent data stream.
Claims4
A method of structuring a screen management system for variable output wherein an application program can present as much information as possible on any video display device without specifiying display geometry or adjusting for said geometry in said application program, said screen management system including a mapping service which accesses the screen definition for an intended video display device and said application program including application services, said method comprising the steps of:
- establishing a dialog between said mapping service and said application services;
- and
- using said application services by said mapping service to generate a device dependent data stream such that a maximum quantity of information is generated and processed for display on said intended video display device based on said screen definition which specifies the quantity, order and placement of the application program's information on the screen.
