This bachelor thesis deals with the redesign of the Kappka application for blood donors. Research in the literature deals with the methods that are used for redesign, as well as a comparison of similar applications that are available. The practical part deals with the business goals of the Kappka application and then with the design of a new interface. The design of the new interface is achieved through the user testing of the current application, followed by the design of paper screen prototypes. Based on the testing of these prototypes, an interactive prototype is implemented in the Figma tool. The interactive prototype is also tested, and a prototype application is implemented in the Flutter framework. The application, in contrast to the current version, notifies the user when he went to donate and whether he can go to donate again and then facilitates his access to information about transfusion departments. In the end, there is a discussion about functions that are implementation-intensive and currently unfeasible, but can serve to develop the user interface in the future, and a discussion of a suitable implementation platform together with Ondřej Marz, author of concurrent work on the Kappka application profile.

The Czech manufacturer of furniture and mattresses with 80 employees has been running its own tailor-made e-shop for several years. However, this e-shop is still only a~secondary sales channel alongside brick-and-mortar stores. In particular, the company would like to sell more mattresses on the e-shop. The company's hypothesis is that users find it difficult to navigate the mattresses on the e-shop or get stuck in the buying process. The aim of this paper is to test this hypothesis, analyze the weak points, suggest changes and then test them. Both quantitative and qualitative analysis, in particular user testing, was used to achieve the objective. The results of the analysis revealed issues that negatively affect the user experience and~sales of the e-shop. Based on these findings, a brief was created for the development of a new version. After implementation, this new version was analyzed again. The analysis showed an improvement in the conversion rate as well as~improvement in the UX of the e-shop. In conclusion, this paper provides specific recommendations for further development of the e-shop and~shows that a systematic approach to~analysis and~optimization can contribute to~success in~online sales.

This master's thesis focuses on creating a reservation system for the Department of Software Engineering at the Faculty of Information Technology, Czech Technical University in Prague (FIT CTU). It includes an overview and analysis of application development, emphasizing maximum user-friendliness and meeting all functional and non-functional requirements. Based on these insights, various implementation options were considered, including modifying existing solutions, alternative approaches such as no-code and low-code platforms, and developing a completely new application. After thorough consideration, the decision was made to create a new application using the high-code method. During the application development, emphasis was placed on meeting all requirements of the IT department and users. This approach was chosen with consideration for the specifics of the faculty environment. The thesis was developed in collaboration with the IT department to achieve maximum sustainability and long-term operation of the resulting application.

This thesis addresses the challenge of allowing visually impaired users to independently utilize the services provided by the website \href{https://hapticke.mapy.cz}{hapticke.mapy.cz}, which offers tactile maps designed for tactile perception through touch. These maps are derived from standard map sources and converted into simplified black and white graphics optimized for tactile perception. Currently, visually impaired users encounter difficulty in selecting the necessary map sheets independently, relying on sighted assistance due to the inaccessible selection process. To address this issue, a web-based Chat Application with an AI assistant from OpenAI was proposed to aid in map selection and ordering. An MVP version of the application was developed; however, subsequent testing with a blind user revealed that the UI of this new application was not yet ready for use by the visually impaired, primarily because it did not support standard assistive screen readers. Feedback from testing sessions has led to plans for collaboration with Theseus, an organization dedicated to making the web accessible. We are currently awaiting feedback from Theseus to start this collaboration, with the goal of making the UI fully accessible and preparing the backend for integration with the Tactile Maps service. The outcome of this project is a functional MVP version of the application where the AI assistant is set up and operational, meeting the functional requirements. However, the user interface component of the application is not yet prepared for visually impaired users. Future work will focus on enhancing the accessibility of the UI to ensure that the application can truly empower visually impaired users and improve their overall user experience with tactile maps.

The goal of this work is to build on the existing Praha zítra application, whose main objective is to collect and promote information about construction plans in the city of Prague. The thesis will discuss suggestions for its possible improvements from the point of user experience. In addition to improvements to its interface, the thesis will also address the broader context of the overall development of the application. The first part of the thesis is devoted to the analysis of the existing solution from its technical aspect. In addition, the thesis also discusses other solutions that have the same purpose as the application. In this part, the cooperation with the owner of the application is also established and several meetings with the team responsible for the application are held, for a deeper understanding of the application functioning and the institution that has the application under it's management. Many shortcomings are identified both on the side of the application and on the side of its planning and development. Shortcomings like these may pose major problems in the future development of the application. In the second part of the thesis, I will propose a set of changes that should bring improvements to the usability of the application. These suggestions are discussed with the staff of the institution involved with the application. Based on their feedback, a working prototype is then created in Figma to visualize the proposed changes, but also to be used in the future development of the application. The output of the thesis also includes other recommendations to help make this future development especially more efficient.
