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.

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.

Abstract Graphical user interfaces are widely common and present in everyday human–computer interaction, dominantly in computers and smartphones. Today, various actions are performed via graphical user interface elements, e.g., windows, menus and icons. An attractive user interface that adapts to user needs and preferences is progressively important as it often allows personalized information processing that facilitates interaction. However, practitioners and scholars have lacked an instrument for measuring user perception of aesthetics within graphical user interface elements to aid in creating successful graphical assets. Therefore, we studied dimensionality of ratings of different perceived aesthetic qualities in GUI elements as the foundation for the measurement instrument. First, we devised a semantic differential scale of 22 adjective pairs by combining prior scattered measures. We then conducted a vignette experiment with random participant (n = 569) assignment to evaluate 4 icons from a total of pre-selected 68 game app icons across 4 categories (concrete, abstract, character and text) using the semantic scales. This resulted in a total of 2276 individual icon evaluations. Through exploratory factor analyses, the observations converged into 5 dimensions of perceived visual quality: Excellence/Inferiority, Graciousness/Harshness, Idleness/Liveliness, Normalness/Bizarreness and Complexity/Simplicity. We then proceeded to conduct confirmatory factor analyses to test the model fit of the 5-factor model with all 22 adjective pairs as well as with an adjusted version of 15 adjective pairs. Overall, this study developed, validated, and consequently presents a measurement instrument for perceptions of visual qualities of graphical user interfaces and/or singular interface elements (VISQUAL) that can be used in multiple ways in several contexts related to visual human-computer interaction, interfaces and their adaption.

Localizing user interfaces has been proven beneficial for both user satisfaction and work efficiency; however, current localization methods disregard the many facets in the cultural background of today‘s typical user by simply adapting to a certain country. The chapter proposes a new approach to localization by modeling the user’s culture according to its understanding in cultural anthropology. Contrasting this view with cultural influences on user interface perception and preferences, the authors obtain an intersection of aspects that need to be included in a cultural user model, and deduce which user interface aspects have to be adaptable. With this, the chapter turns towards the application of their approach with the help of adaptive user interfaces, which allow the flexible composition of different user interface elements. The authors describe one possibility for implementing such culturally adaptive systems, and exemplify the design of different gradations of user interface aspects with the help of their MOCCA system.

Formal Distribution

The rapid growth of computing devices has led to the emergence of distributed user interfaces. A user interface is called distributed if a user can interact with it using several devices at the same time. Formal methods for designing such interfaces, in particular methods for the distribution of interface elements across multiple devices, are yet to be developed. This is the reason why every time a new application requires a distributed user interface, the latter has to be designed from scratch, rendering the entire venture economically inefficient. In order to minimize costs, unify and automate the development of distributed interfaces, we need to formulate general formal methods for designing distributed interfaces that will be independent from a particular application or device. This article paper proposes a formal distribution method based on the pi-calculus.

Human perception of time is fluid, and can be manipulated in purposeful and productive ways. In this chapter, the authors describe and evaluate how progress bar pacing behaviors and graphical design can alter users’ perceptions of an operation’s duration. Although progress bars are relatively simple, they provide an ideal playground in which to experiment with perceptual effects in user interface design. As a baseline in the experiments, the authors use generic, solid-color progress bars with linear pacing behaviors, prevalent in many user interfaces. In a series of direct comparison tests, they are able to rank how different progress bar designs compare to one another. Using these results, it is possible to craft perceptually-optimized progress bars that appear faster, even though their actual duration remains unchanged. Throughout, the authors include design suggestions that can contribute to an overall more responsive, pleasant, and human-centric computing experience.

The Right

User Interface (UI) personalization aims at providing the right information, at the right time, and on the right support (tablets, smart-phone, etc.). Personalization can be performed on the interface elements’ presentation (e.g. layout, screen size, and resolution) and on the content provided (e.g., data, information, document). While many existing approaches deal with the first type of personalization, this chapter explores content personalization. To that end, the authors define a context-aware Model Driven Architecture (MDA) approach where the UI model is enriched by data from a domain model and its mapping to a context model. They conclude that this approach is better used only for domains where one envisions several developments of software applications and/or user interfaces.

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.
