Conference Paper
People with visual impairments suffer because of the lack of well prepared educational resources, especially in the field of mathematics. Existing translation software provides a way to convert basic math documents into Braille language or speak them through Text-To-Speech (TTS) engines, but it requires constant users's interaction and detailed pre...
Conference Paper
The article contains the proposal of the standard log file format for activity tracking purposes. The retrieval process for Activity Markup Language (ActML) in different software environments was discussed, alongside with the test suite of multi-platform mobile applications. The next part of the article deals with automatic comparison of acquired a...
Conference Paper
The chapter concerns the security of pattern unlock procedure for mobile, touch-enabled devices. There is a novel measure for automatic estimation of the pattern strength proposed and compared with human ratings. The results of the surveys among mobile users confirm the convergence between objective security requirements incorporated into the measu...
Article
The article contains a survey of methods of the mobile development with the FMX Applica- tion platform, which allows to build multi-platform solutions for the efficient Human-Computer Interaction. The test projects illustrate some important conclusions regarding the design and testing of mobile applications for iOS and Android operating systems. Th...

The paper presents the idea and implementation details of a novel tool intended for detection of plagiarism in mathematical content of LATEX files. The proposed algorithm compares LTeX files and detects possible similarities in mathematical formulas, providing an objective similarity score. It offers two modes of comparison: direct (symbolic) mode...
Chapter
The paper concerns the problem of dependability of multi-platform mobile applications developed with FMX framework. Intended for simultaneous development of applications dedicated to multiple mobile platforms, FMX enables faster testing at desktop environment, convenient porting the project to another target platform, as well as internationalizatio...
Chapter
The paper concerns the influence of memory, forgetting and timing issues on the security of mobile applications. The designed framework system was used to further elaboration of the automatic measure, which estimates the quality (strength) of unlock gesture patterns. The data analysis described in detail presents the relations between human subject...
Chapter
The paper surveys the execution features of ready-to-use sorting procedures in various modern computer languages/compilers. The chosen sorting functions were tested for randomly generated data sets of different size and structure resembling the lists or arrays commonly used in real life IT solutions. Our results reveal some differences between part...
Chapter
Full-text available
The chapter concerns the implementation of novel and advanced HCI (human-computer interaction) methods in the design of educational systems aimed at people with disabilities. E-learning applications can significantly improve the quality of life for handicapped students by increasing their self-reliance and adjusting the learning time frame. The str...
Conference Paper
In this paper we present a multiplatform research framework for acquisition of pattern locks and evaluation of their strength. Along with the design features of the framework itself we provide the analysis of the data set of more than 300 pattern locks acquired by means of this solution. In particular we compare the subjective human rating of patte...
Conference Paper
Full-text available
The paper concerns the design and implementation of a search engine for mathematical expressions given by the user in a convenient form of natural language or visual queries. Proper presentation and transcription of the mathematical notation is substantial for further processing and the adequate choice of the word distance measure for string compar...
Conference Paper
The paper concerns the indoor location services with the use of the beacon technology and multi-platform software tools. There is the test application and environment simulating a room in the museum presented. The proposed system was used to elaborate the heuristic parameters for stable and accurate determination of the nearest beacon. The results...
Article
Rynek związany z urządzeniami mobilnymi to najbardziej dynamicznie rozwijająca się gałąź przemysłu IT. W pracy przedstawiono analizę wpływu jakości interakcji człowiek-komputer (Human-Computer Interaction, HCI) na popularność aplikacji mobilnych. Opisane zostały zarówno formalne normy branżowe, jak i rozwiązania wynikające z bieżących trendów, wyzn...
Conference Paper
The chapter contains a survey of the biometrics with the focus at behavioral methods. The aspects of human-computer interaction modeling were described as well. The experiments proved that the user’s activities in the computer system may become a pattern for the identification algorithm, introducing HCI methods in the area of the biometrics. This a...

W pracy przedstawiono przegląd aplikacji wspomagających zarządzanie przedsiębiorstwem ze szczególnym uwzględnieniem funkcji kontrolnych i nadzorczych. Funkcjonalność przedstawionych aplikacji jest różna, poczynając od modelu współdzielonego kalendarza, poprzez rozbudowane programy pocztowe, aż do złożonych serwerów pracy grupowej. Tak więc dobór i...
Article
In the paper an algorithm for an automatic recognition of the structure of mathematical for- mulae saved in a graphical form has been presented. The described method is based on 2D graph grammars, although the other approaches were mentioned. Moreover, the heuristic rules used during the simplification of the initial data structure, the example gra...
