A NALYSIS AND E VALUATION OF C OGNITIVE B EHAVIOR IN S OFTWARE I NTERFACES USING AN E XPERT S YSTEM

In most of the situations, usability evaluations of software interfaces are done by usability experts. Using such professionals needs a certain dimension in business. So, in a lot of small and medium scaled company's, software developers are compelled to learn to manage usability factors. This is not much simpler than training usability engineers on how to create a software application. As a remedy, an expert system CASI for software developers has been designed. In this paper, the expert system of Cognitive Analysis of Software Interfaces (CASI) is outlined to integrate cognitive modelling concepts and is considered as a crucial process for the development of interactive software interfaces. The recommended expert system is entirely dependent on the complete analysis of the user actions and specifications that display the psychological strategy of particular users. Moreover, this system helps designers and software developers to evaluate software prototypes in an intelligent way based on user perception and evaluation views. The paper presents a case study on the development of a rehabilitation database for a person with physical limitations. The results mentioned in this paper show that with the help of the expert system CASI more usability problems in the software interfaces can be detected. Hence, enhancing the usability of software interfaces by an automated CASI system is feasible.
