Abstract:

Many vendors produce high-performance, low-cost training hardware, but bundle their products with proprietary software interfaces. Because these interfaces are proprietary, courseware and authoring systems written to operate on one set of hardware will not run on a competitors hardware. Expensive reprogramming is needed to adapt to new hardware. These reprogramming costs can be eliminated by adopting standard software interfaces. The objectives of this effort were to describe and develop a standard software interface that will allow training systems to be assembled from separate plug-and-play components in the same way that stereo systems can be assembled from separate speakers, amplifiers, and other components. The Portable Courseware PORTCO architecture consists of two interfaces, the Device Services Interfaces and the Device Handler Interface. It also contains three layers application, routing and configuration, and device handler. This architecture should allow applications software to run on any compliant set of hardware components. The series of reports describing the PORTCO architecture should direct development of portable MS-DOS applications and standard peripheral device handlers. This report provides an overview of the PORTCO architecture and should be of interest to all who are concerned with computer-based training. kr
