Constructing User Interfaces Based on logical Input Devices

Can a general-purpose interactive system do specific tasks without costly extras? With this Method, which uses a configuration generator, customized programs may indeed be possible.

Because of the rapidly decreasing costs and increasing power of the new generation of microcomputers, interactive computer systems will soon be prevalent in both industrial and private sectors. But the hardware development has made much more progress than software engineering techniques. Already, everyone is speaking of a software crisis, which will rapidly become worse as a wide variety of devices becomes available for an even wider variety of applications. In addition, interactive software must support users with quite different skills and intererAs.

To overcome the software problems, we urgently need a methodology for the design of interactive systems. Such a methodology would provide a unified concept of requirement diversity, improve the design of humancomputer interfaces, identify, and possibly standardize, a set of interaction techniques, and ease the construction of customized systems.

Customers want systems that perform only the desired tasks without extra overhead. Vendors therefore must offer a large number of inexpensive specialized systems rather than a small number of general-purpose systems. Suitable software techniques have to be developed that ease the production of custom-made systems.

Research in the standardization of graphics systems can offer solutions for these problems for two reasons. One benefit, which is the focus of this article, is that a standard general-purpose system is a suitable basis for deriving adapted standard systems. A second benefit, related to the role of computer graphics in human-machine interaction, is that the graphic representation of information is undoubtedly the most important means for good humanmachine interfaces.

We use graphics to address the human visual sense, specifically visual reception. Graphics techniques can be used to give an instantaneous overview and impression of an application problem and to represent tiny details immediately following the overview~or even in parallel, if needed. These capabilities are even more important when working interactively. Operators sitting in front of a terminal working on their models and thereby communicating with a computer system usually expect an immediate response to their actions. The respo...
