Many companies invest large amount of money in developing new technology, without knowing how it will be used. To succeed in making these technologies useful it is necessary to understand the context that gives meaning to the artifact. In the case of generic products, especially in new domains, the context is not obvious. This bachelor thesis analyses what Usability Engineering, Participatory Design and Ethnography can contribute to the problem of learning about the context of usage for generic artifacts. Understanding and identifying details of context is considered to be important to achieve usability in software development. The experience is that most recommendations on usability methods concern situations of specific users in a specific context. In order to find important aspects of the real-world use of generic products, we suggest that ethnographic studies can be conducted in contexts where behaviors relevant to the design are thought to be found. The problem of not knowing the context was experienced in usability work practiced in a large software engineering project. The project task was to develop a web browser for Symbian's ?Quartz? reference design for handheld devices. Methods used were taken from participatory design and usability engineering.

Lösenordshanterare har länge varit tillgängliga och det finns mycket forskning som tyder på att användningen av dem är begränsad. Deras funktionalitet hjälper användaren att generera och spara unika och starka lösenord för varje individuell inloggning. Vi utformar en enkät med hjälp av tidigare forskning och en modifierad version av teknikacceptansmodellen i syfte att undersöka demografiska variablers påverkan på användningen av lösenordshanterare. Undersökningen bedrivs genom att kvantitativ data samlas in från den digitala plattformen reddit.com. Denna data analyseras därefter med hjälp av statistiska metoder, där vi kommer fram till att det finns signifikanta skillnaderivariablernakön,geografiskplats,antalunikalösenordochdatorvana. Dessa variabler påverkade både den faktiska användningen, men också attityden till systemet. Vi diskuterar detta resultat utifrån den presenterade teorin och relaterad forskning. / Password managers have been available for a long time, and there has been a lot of research showing that these tools are not commonly used.

Thesis describes design and implementation of a web browser game, which can be played by multiple players via the internet. The main goal is to manage the economy, although players can cooperate (trading) or play against each other (battles). NoSQL database is used for persistent storage of progress, which is also described in the thesis. Apart from human players there are also agents/bots, which play the game autonomously via state machines generated by genetic algorithms. Paper describes design and functionality of either the genetic algorithms, but also the state machines.

This thesis discusses possibilities of accelerated 3D scene displaying in a Web browser. In more detail, it deals with WebGL standard and its use in real applications. An application for visualization of volumetric medical data based on JavaScript, WebGL and Three.js library was designed and implemented. Image data are loaded from Google Drive cloud storage. An important part of the application is 3D visualization of the volumetric data based on volume rendering technique called Ray-casting.

Tento projekt se věnuje problematice zobrazení velkých hierarchických struktur, zejména možnostem vizualizace stromových grafů. Cílem je implementace hyperbolického prohlížeče ve webovém prostředí, který využívá potenciálu neeukleidovské geometrie k promítnutí stromu na hyperbolickou rovinu. Velký důraz je kladen na uživatelsky přívětivou manipulaci se zobrazovaným modelem a snadnou orientaci.

This thesis deals with the design and implementation of the document modifications and another annotation editor improvements developed as the part of the Decipher project. Explains the nature of the Decipher project and the inclusion of annotation system 4A in this project. It examines the annotation editor and propose solutions to problems and adding new functionality which makes it easier to work with annotations and also with editor itself.

This thesis deals with the changes in the pattern of Internet content consumption caused by the new types of device, such as smart phones and tablets. In the second Chapter following the introduction, these devices are introduced, as well as their users. The third and crucial chapter first discusses how changed the activities that we have performed on a PC or laptop. The next section presents a completely new activities that occurred up with smart phones such as geolocation games and mobile tagging. The fourth chapter focuses on the mobile internet in the Czech Republic. Part of this charter is a private research / comparison of 100 most visited websites, when the endpoint was to determine how the authors of these sites are prepared for mobile visitors.

The main objective of this work is to design and implement an application that can be used as an aid for the education of programming essentials. Particularly, the attention focuses on the domain of dynamic data structures. The target application will be implemented with the use of web technologies so that it can be run in an ordinary WWW browser. First of all, a brief introduction recapitulates the data structures to be covered. Then the work summarizes the usable technologies available within the web browsers with the focus on the particular technology (which is DHTML) that will become the target platform. The most significant part of this work then discusses the design of the final application. This rather theoretical part is then followed by the description of the practical implementation. A short user manual is also included.

Cieľom práce je navrhnúť a vytvoriť hlasom ovládaného asistenta(voicebota), ktorý bude ľahko nasaditeľný na webovú stránku. Používateľom tak bude poskytnutý moderný spôsob, ako prirodzene komunikovať cez internetový prehliadač. Hlavný dôraz je kladený na synchronizáciu medzi hlasovým asistentom a obsahom na webovej stránke. Synchronizácia je dosiahnutá obojsmerným prenosom hlasu a textových príkazov medzi klientom a serverom. Na to je použitá technológia WebRTC v kombinácií so signalizačným protokolom SIP. Práca sa zaoberá oblasťami ako VoIP telefonovanie, počítačové siete a strojové učenie(proprietárne rečové technológie od Phonexie). Benefitom nasadenia hlasového asistenta je zníženie nákladov na odchádzajúce hovory pre klientov, odľahčenie agentov na call centrách pri odpovedaní na často kladené otázky a zvýšenie záujmu zákazníkov vďaka použitiu nových technológií.
