The overall development of information systems and their increasingly significant impact on all areas of the society expressed in such terms as "information society", etc., determines the increasing importance of user interfaces. Moreover, the quality and adequacy of the interface to the tasks of the subject area becomes the determining parameter when choosing a specific organization software product for computer support of the organization. The study of user interfaces involved with the 70s of the last century. Some methods of interface quality research, in particular, the GOMS method is used to date. However, the use of advanced training technology for mass professional users of information systems for the study of interfaces allows to effectively evaluate the interface in the learning process without using the GOMS method. This article is devoted to this issue. The article deals with the method of quantitative evaluation of the quality of the user interface in the form of such characteristics as errors and mental time of the tasks of the subject area. The structure of time of performing tasks of the subject area is analyzed. Mental time is allocated as the characteristic that chiefly determines the usability of the user interface. Mental time is based on the total time of the step, the calculation time at this step, and the mechanical time required for a person to perform an action that causes the step to be performed. It is shown that the use of anticipated training technology of mass professional user can significantly simplify the allocation of mental time by eliminating the time of the task computer. In the structure of time, the mechanical time required for a person to perform an action that causes the step to be performed is essential. In the GOMS method some standard numerical characteristics are used to estimate mechanical time. However, a hypothesis is put forward, and it is experimentally shown that a statistically significant minimum time for performing actions can be used as mechanical time. This hypothesis was experimentally confirmed. The method and results of this experiment are presented in the article. Developed on this basis, the methodology for assessing the quality of the interface can be used when retraining users in the process of transition of organizations to domestic software in order to evaluate the interfaces.

In this paper we describe how existing software developing processes, such as Rational Unified Process, can be adapted in order to allow disciplined and more efficient development of user interfaces. The main objective of this paper is to demonstrate that standard modeling environments, based on the UML, can be adapted and efficiently used for user interfaces development. We have integrated the HCI knowledge into developing processes by semantically enriching the models created in each of the process activities of the process. By using UML, we can make easier use of HCI knowledge for ordinary software engineers who, usually, are not familiar with results of HCI researches, so these results can have broader and more practical effects. By providing a standard means for representing human computer interaction, we can seamlessly transfer UML models of multimodal interfaces between design and specialized analysis tools. Standardization provides a significant driving force for further progress because it codifies best practices enables and encourages reuse, and facilitates inter working between complementary tools. Proposed solutions can be valuable for software developers, who can improve quality of user interfaces and their communication with user interface designers, as well as for human computer interaction researchers, who can use standard methods to include their results into software developing processes.

The development of e-learning, both in distance and mixed forms, becomes especially relevant in the modern educational process. A high-quality e-learning course is developed through the efforts of two parties: the teacher, who creates the methodological content, and the programmer, who creates the electronic shell of the course. The article substantiates the importance of quality issues in the development of a user interface for electronic educational resources, since the user of an electronic course deals with the direct implementation of educational material. The indicators for assessing the quality of software products in accordance with international and Russian standards and their applicability for assessing user interfaces of electronic educational resources are analyzed. The conclusion is made about the importance of the indicator “practicality” in relation to this type of software product as an indicator of an individual evaluation of the use of a product by a certain user or circle of users. The classical methods for assessing the quality of the human-machine interaction interface and the applicability of experimental and formal methods for assessing quality are considered. The analysis of modern approaches to the design of user interfaces based on UX/UI design is given. An assessment of the requirements and criteria for assessing the user interface from the standpoint of modern design is given. The tasks and features of the UX and UI components of the design process are analyzed. The essence of the modern term “usability” as an indicator of the interface evaluation is explained, and the qualitative evaluation criteria for this indicator are considered. The concept of UX testing is given, the main stages of this process are considered. The importance of taking into account the subjective psychological factors of interface perception is substantiated. The indicators for assessing the quality of user interfaces, based on the cognitive factors of its perception by a person, are analyzed.

This paper presents a model-based approach to build Information Systems User Interfaces (ISUI). In this approach, UI presentation and behavioral aspects are modeled as UI Stereotypes, which are high level abstractions of UI appearance and interaction features. A taxonomy of ISUI elements is proposed as the basis for definition of UI stereotypes. These elements are orchestrated on a software architecture which manages model-based UI building and integration with the IS applications. The proposed approach reduces software development efforts and costs, facilitating maintenance and evolution of ISUI. Moreover, UI stereotypes improve usability, consistency, reuse and standardization of both presentation and behavior of ISUI.

Introduction. The article presents a model of one of the possible indicators of the quality of user interfaces (PIN) of automated workplaces of operational units of emergency and emergency rescue services (EiASS), namely, the linearization indicator that takes into account the psychophysiological features of human perception of visual information. Goals and objectives. Reducing the response time of the operational units of the EiASS by reducing the time of their dispatching. Development of a mathematical model and an algorithm for calculating the linearization indicator of PIN elements (EPIN), which allows estimating the dispatch time depending on their relative location on the monitor. Methods. Methods of set theory and relational algebra were used to construct a PIN model and an algorithm for calculating the linearization index. To describe the PIN configuration, the concepts of an archipelago and a frame of interface elements are introduced. Results and discussion. The success of the EiASS actions largely depends on the dispatch time, during which the required number of units is determined and sent. Therefore, the time spent on solving dispatching tasks is one of the most common and objective indicators of the quality of the PIN. The best of the investigated automated workplaces will be the one with the specified time less. However, the time indicator gives an idea only about the relative time - the time of operation of one automated workplace relative to another. And it does not give any idea of the absolute time that would be spent on solving the problem by some abstract automated workplace with an optimal EPIN configuration. For this reason, an indicator that is sensitive to the PIN configuration has been developed. The indicator gives an answer to the question of why one automated workplace is better than another, and can be used to optimize the layout of the PIN. Conclusions. Based on the proposed model, an algorithm for calculating the numerical values of the linearization indicator of user interface elements sensitive to their size and relative position on the monitor of the EiASS operator is developed. This allows you to optimize the user interface according to the criterion of time for solving tasks and, accordingly, reduce the dispatching time of the operational units of the EiASS.

The quality of educational support materials utilized in schools contributes greatly to the quality of education that is delivered during an instructional process. In recent years, there has been rapid expansion in digital content development, dissemination and access in schools. Many initiatives geared towards development and provisions of digital content to schools in Kenya have been witnessed. However, little has been done to ensure that the educational digital content design aspect such as user interface is appropriate for the instructional process. This study therefore investigated the effect of the user interface on the utilization and efficacy of educational digital content among secondary schools in Kenya. The study was guided by three specific objectives including to: analyze the layout of the various components of educational digital content in secondary schools; examine the navigational tools in the educational digital content and assess the effect of user interfaces on the utilization of educational digital content in secondary school. A descriptive survey design was used for the study which involved fifteen Economic Stimulus Programme phase 1 secondary schools in Nairobi County. Three research instruments, that is, teacher questionnaire, learners’ focus group discussion guide and digital content analysis sheet were used to collect the required data. The collected data was analyzed through descriptive statistics and presented in form of notes, tables, and figures. The study established that there were issues with interface and navigational tools in educational digital content user interface which affected content utilisation and consequently its efficacy. To address the design issues of the content, the study recommended that developers design appropriate user interfaces with adequate and standard navigational tools that will make educational digital content navigation and utilization easy for users.

Concept Of Information

The concept of information systems user interface quality has multidimensional content, which is difficult to isolate and measure due to the lack of a formalized model for assessing quality and terminological differences of quality indicators in standards. This work is aimed at finding solutions for using well-known software quality models in the interest of evaluating the user interface. The ratio of user interface assessment parameters to their presence in software quality assessment models is established; drawn regarding their evolutionary transformation are conclusions.

Adaptive User Interfaces

This thesis reports on original exploratory study that is aimed at contributing towards understanding of factors that influence Africa users support for alternative object metaphors for user interface icons. One of the great impediments for efficient utilization of information systems is the existing gap between system designs that typically follow western cues for crafting user interfaces and actual users who use those systems within their diverse cultural frames. The problem remains important because of the wider penetration of information systems, which serve as modern technology tools to improve service provisioning worldwide. In order to overcome the problem of optimum utilization of information systems, previous studies have proposed culturally adaptive user interfaces. The basic principle behind culture adaptive interfaces is to develop intelligent user interfaces that can automatically adapt to user contexts. However, the challenges with the new proposals for adaptive user interfaces are how to best model information about users, how to access the cultural background of individual users and empirically examine the effects of culture on user interface preferences. In order to properly contribute to solving these problems, an exploratory study was conducted to empirically establish African rural users support for alternative village object metaphors, examine effects of culture on user support and investigate response characteristic among culturally diverse user groups. The synthesis of bodystorming and cultural probes methodology was applied to engage the participation of African rural users in the study. Technology support model was developed to measure user knowledge, comprehension, skills, performance and support for alternative African village metaphors as interface icons. The partial least square analytic modelling technique and finite mixture path segmentation model were used to test a set of research hypotheses and detect heterogeneity in 71 respondent data generated. Experimental results of this study show that human cognitive factors of technology knowledge, comprehension and performance influence African users support for alternative village object metaphors as interface icons. However, skill factor is not found to influence user support for alternative African village object metaphors. The factor of culture is found to moderate the effects of comprehension on user support and effects of user performance on user support. This study also identifies three segments of African users that result in heterogeneity within the inner path model.
