Google Glass is a new personal computing device that employs an over-eyetransparent display together with voice-control in order to offer audiovisual informationto the device's users. Glass is also a new mediated-reality platform,fundamentally different from common computers and smartphones, and theavailable Glass application (Glassware) design guides do not fully cover human-computer interaction issues that are imposed by Glass' characteristics – issuessuch as optimum information density, use of colourization and positioningto separate information, optimum amount of discrete entities on display, and theuse of iconography. By combining existing guidelines for Glassware UI designwith past research on human-computer interaction and psychology, those issuescan be addressed and can lead to additional design principles. To evaluate theefficacy of such combinations within the technical and design limitations imposedby Google Glass, a set of UI mock-ups for fictional Glassware is createdand used in multiple surveys to acquire data on human response to those combinedfactors. During the study, it was determined that factors including colourization,element positioning and use of icons have a definite effect on user perceptionand preferences, whilst factors related to information density andamount of discrete entities on screen are less relevant. Additionally, supportingevidence was found in relation to the assumption that utility is more importantthan functionless aesthetics. As a result, a UI design guideline set was formulatedthat can be used to supplement existing UI design guidelines for GoogleGlass and similar over-eye transparent-screen devices.

The goal of this diploma thesis is to design, realize and implement a software application in a corporate environment. The application is based on the basic principles of information systems. It allows to store, process, send and display the necessary internal data at one place. The result of the diploma thesis is a custom made applicationfor the company. This application is implemented in a corporate environment.

The subject of this master’s thesis is a software application assessment followed by proposal of modifications that should contribute to improving the application. The thesis includes theoretical background necessary for general knowledge of the problem, thorough analysis of the current situation and proposal of solution, which includes decision about necessity of modifications for selected application parts and proposal of specific modifications. The solution also includes recommendation about testing methods that should be used to test the impact of the specified modifications.

This diploma thesis covers the design and implementation of changes and extension modules of a chosen information system, used in JUDr. Ján Bartánus's attorney office in Ružomberok. The system, implemented as a web application based on the Symfony framework, is dedicated to the simplyfing, monitoring and organization of the work processes in a generic attorney office located in the Slovak Republic. For the purposes of a correct design, the thesis contains an analysis of the current state of the given attorney office, the environment in which it operates, its information system and existing solutions. Tools that were used to conduct the analysis were the SLEPT method, Porter's five forces, model 7S and SWOT matrix. Based on the results of the analyses, a change of the system has been designed, which entails an upgrade of the system, its user interface, integration of the register of companies of Slovak Republic and an extension module intended for the financial valuation of work performed by an attorney. The application has been developed utilizing the PHP and JavaScript programming language. The valuation module integrates the Google Maps API. The stability and speed of the system were tested by functional tests and profiling of the duration of HTTP requests. The main contribution of this thesis is the design and implementation of an extension of the information system, which can be used in any arbitrary attorney office situated in the Slovak Republic, and its practical application in the chosen company. This thesis builds on a previous thesis dedicated to the design and implementation of the information system, which is being extended in this diploma thesis.

This Master's thesis deals with the development of a mobile application for a control of the supervisory system in caravans and motorhomes. The thesis presents the currently available principles and research of the existing solutions. This custom solution includes an Android application and a desktop application of the central unit simulator of the supervisory system. The simulator is based on the Node.js and node-webkit technologies. The simulator communicates with the devices available via RF Transciever and it simulates other devices. The mobile application communicates with the simulator via Bluetooth Low Energy and GSM. Major part of the implementation description is devoted to the Bluetooth Low Energy technology and to issues, which are associated with it. The resulting solution puts emphasis on the usability of the user interface and the ability to supervise a wide range of connected devices. The system also implements custom logic alerts for tracked events. The thesis concludes with evaluation of the resulting system and outlining the future development options.
