Abstract The paper discusses the problem of poor quality of graphical user interfaces used for various software products. The provided analysis shows that modern software has poor-quality interfaces, and there are no flexible programs for evaluating such interfaces. The paper highlights and describes the characteristics that are used to assess the quality of interfaces, such as operator speed, error rates, skill retention, and subjective satisfaction. A formalized approach to assess the speed of searching for information and functional objects is proposed. It is based on such characteristics as the time of fixation of the gaze, movement of the eye, the volume of a person’s operative memory, the zone of clear vision, the path of the user’s gaze information search. An algorithm for estimating the speed of searching for information and functional elements is proposed. This algorithm can be implemented and used for further design of a software application based on it. The algorithm makes it possible to automatically evaluate both a particular interface and to compare the interfaces of different programs.

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.

Human interactions with computers are often via menus, and “in order to make information retrieval more efficient, it is necessary that indexes, menus and links be carefully designed” (Zaphris, Shneiderman, & Norman, 2002, p. 201). There are a number of alternatives to menus, such as icons, question-and-answer formats, and dynamic lists, but most graphical user interfaces are almost entirely menu-driven (Hall & Bescos, 1995). Menu systems have many advantages. For example, Norman (1991) identified low memory load, ease of learning and use, and reduced error rates as advantages of menu-driven interfaces. They frequently form the main part of a WYSIWYG (What You See Is What You Get) interface, providing most of the functionality in the more common operating systems such as Microsoft Windows. Consequently, familiarity also can be added to the list of advantages of using menus when accessing computer systems. These aspects are particularly important when considering public-access technologies, where individuals from across the population exhibiting a range of ages, skills, and experience levels will attempt to use the systems. Further, training or the opportunities for training will be minimal and, most likely, non-existent.

And Task

Nearly all software products have rigid and predefined interfaces. Users are usually unable to modify or customize features beyond cosmetic aspects. Interface adaptability is important because aspects such as user preferences and task sequences vary widely in engineering, even within specialized domains. A methodology for the creation of adaptable user interfaces using model composition is presented in this paper. User interfaces are generated dynamically through the composition of model fragments that are stored in a fragment library. When fragments are linked to models of physical behavior, interface model composition applications are likely to be easier to extend and maintain than traditional graphical user interfaces. A prototype system within the domain of bridge diagnosis illustrates the potential for practical applications.

The author has studied the main problems of operational-search support for the finding missing children. Achieving the article’s objective (to identify the current problems of operational search support for finding missing children) required the use of a sociological method of research (interrogation). To collect empirical data, 228 criminal police officers were questioned as the main investigators for missing children. The analysis and generalization of the respondents' answers enabled the author to come to the following conclusions: 1. The effectiveness of the search for missing children is considered sufficient. The level of operational search support for missing children is estimated to be average. 2. The main common reasons (factors) that affect the effectiveness of the operational-search support for missing children include: the quality of the organization of operational-search support for missing children; logistics. Specific reasons (factors) that affect the effectiveness of the operational-search support of finding missing children are: the quality of regulatory support; the quality of information and analytical support; officer’s experience; timely conduct of search operations; correct assessment of available information; correct presentation of versions; ignoring one or separate versions; the number of officers involved. 3. The timely establishment of the whereabouts of missing children is mainly carried out within 24 hours during criminal proceedings (prior to the initiation of the operational-search case) or without the initiation of an operational-search Case and the opening of criminal proceedings, ie before registration of the notification in a single register of pre-trial investigations, with subsequent registration in the single record. 4. Instruction on the organization of the search of accused, defendants, persons evading criminal punishment, missing persons and identification of an unidentified corpse (order of the Ministry of Internal Affairs of Ukraine dated 05.01.2005 No. 3 "for use only by staff") needs updating and bringing in compliance with practical requirements. 5. Current accounting capabilities for the search for missing children imply a limited choice of information and have the disadvantage of lacking a unified information search system. 6. The most significant problems of operational search support of missing children include: complicated legal and organizational mechanisms of urgent conduct of operational search activities (operational and technical measures) to determine the location of the child; insufficient level of technical support for conducting operational-search measures (operational-technical measures). In this regard, it is advisable to simplify the procedure for deciding whether to conduct an operational-technical (covered investigative (search) action. Less decisive problems are the following: imperfection of agent security; unskilled juvenile prevention officers and poor quality of operational records. 7. The interaction of criminal police units with the public in the search for missing children is insufficient.

Physically Disabled People

The human-machine interaction has evolved significantly in the last years, allowing a new range of opportunities for developing solutions for people with physical limitations. Natural user interfaces (NUI) allow bedridden and/or physically disabled people to perform a set of actions trough gestures thus increasing their quality of life and autonomy. This paper presents a solution based on image processing and computer vision using the Kinect 3D sensor for development of applications that recognize gestures made by the human hand. The gestures are then identified by a software application that triggers a set of actions of upmost importance for the bedridden person, for example, trigger the emergency, switch on/off the TV or control the bed slope. It was used a shape matching technique for six gestures recognition, being the final actions activated by the Arduino platform. The results show a success rate of 96%. This system can improve the quality of life and autonomy of bedridden people, being able to be adapted for the specific necessities of an individual subject.
