Abstract
A method has been developed and implemented to ensure the ergonomics of using the Web interface for customers of a virtual instrument-making enterprise with limited capabilities through the use of expert systems. The essence of this method is to supplement the dialog component of the Information and Analytical Portal (IAP) with a specialized shell of the expert system (ES), which, being filled with knowledge about the limited capabilities of users caused by various pathologies, makes it possible to adapt the interface in the dialogue to the capabilities of a particular user. implementations of this solution method are fully consistent with the results obtained using the principles of interface improvement. However, due to the use in this synthesis method of various approaches to the technology of expert systems development, additional opportunities open up in solving the problem of providing the convenience of using the interface for customers with limited capabilities. When using the proposed method, it becomes possible to simplify the procedure of interaction "man-machine", to solve the problems of people with disabilities, to increase the volume of consumers who have access to advanced information technologies. These facts, confirmed by the results of numerical modeling, showed the effectiveness of the presented method and an individual approach to users with disabilities. The software implementation of the logical-linguistic hierarchical model on the example of “strong myopia” with the help of the production shell ES is proposed and substantiated. As the initial data, information about hardware was used, the use of which, in appropriate cases, will make it possible to increase the ergonomics of the IAP for users with disabilities.
Highlights
Every day Internet technologies penetrate more and more into various spheres of human life, forcing humanity to actively master new technologies
The conducted studies analyzed the usability of methods and tools for developing expert system (ES), which consist in ensuring the convenience of using the interface of a virtual instrument-making enterprise for people with disabilities and require developers to establish the semantics of the subject area of interconnections of complex objects and their relationships, gives an idea of the algorithm of the investigated development of improvement ergonomics of the Web interface
It can be argued that the algorithm of the developed method has a complex hierarchical metasemantic network, in which the properties of the first set are inherited by the second set, and is a collection of facts and statements from the database
Summary
Every day Internet technologies penetrate more and more into various spheres of human life, forcing humanity to actively master new technologies. The modern present takes place in the era of the completion of the third, digital revolution, is marked by the development of information and communication technologies, automation and robotization of production processes, began in the second half of the last century, which will inevitably be replaced by the so-called Industry 4.0, which marks a new level of complete automation of production, where all processes are controlled in real time and taking into account changing external conditions The essence of this priority area is to establish direct contacts between manufacturers and customers by improving the Web interface, taking into account their physical characteristics. In the end – to a qualitatively new economy, capable of bringing any country to the level of highly developed countries, increasing its competitiveness
