Multi-User Cooperation in Augmented Reality on iOS
Jurczyk, Adam ; Kapinus, Michal (referee) ; Beran, Vítězslav (advisor)
The aim of this work was to create a solution that would allow multiple users to cooperate in a shared Augmented Reality environment. The proposed solution enables users to interact and edit a 3D scene in real time. Thesis touches on the subject of how a user interface should look like to assist with synchronization of devices in the shared scene. It also describes a system for user permission and action conflict resolution when dealing with virtual object interaction. A hybrid peer-to-peer architecture is designed to facilitate communication between individual peers. The solution is based on the iOS platform and uses the new functions available in the ARKit 2 framework. The resulting application is used to demonstrate and evaluate how the designed systems perform during multi-user cooperation. The designed solution can be used as a basis for an application that presents work from a designer to a client with the ability to get expressive user feedback in real time and in the intended physical environment.

Augmented Reality in CAVE
Kolčárek, Michal ; Beran, Vítězslav (referee) ; Herout, Adam (advisor)
Tato práce se zaměřuje na technologii Cave Automatic Virtual Environment a konkrétně pak na využití principů rozšířené reality v tomto prostředí. Dává si za cíl odpovědět na otázku, zdali je možné použít v prostředí CAVE existující frameworky pro rozšířenou realitu, konkrétně ty, pracující na platformě iOS. Hlavní důraz je kladen na rozpoznávání markerů v tomto prostředí a na zvýšení přesnosti jejich rozpoznání. Práce odpovídá na množství otázek z této oblasti, jako jaké markery je vhodné použít, jaké jsou omezení a největší obtíže. Výstupem je demonstrační aplikace, pracující na platformě iOS, která v je prostředí CAVE otestovaná a plně použitelná. Tato aplikace by měla vylepšit uživatelský vjem z prostředí CAVE tím, že mu poskytne dodatečné informace a také základní možnosti interakce se zobrazenými objekty.

Iterative Improving of Transcribed Speech Recordings Exploiting Listener's Feedback
Krůza, Jan Oldřich ; Kuboň, Vladislav (advisor) ; Pollák, Petr (referee) ; Müller, Luděk (referee)
Iterative Improving of Transcribed Speech Recordings Exploiting Listeners' Feedback Abstract This Ph.D. thesis deals with making a corpus of audio recordings of a single speaker accessible to wide public and interested community. The work has been motivated by the existence of a set of perishing recordings of the Czech philosopher Karel Makoň on magnetophone tapes. The aim is to conserve the material for future generations and to make it accessible using digital technologies, in particular publishing the recordings online and enabling the users to search through them. The thesis introduces the creation of a system for transcribing a large set of speech recordings employing a lay community. The solution designed is based on obtaining a baseline low-quality transcription by means of automated speech recognition and developing an application that allows for collecting corrections of the automatic transcription in a fashion that makes it usable as training data for further improvement of said transcription. The spoken corpus itself is described. The author and his works, topics cove- red in the talks, the process of recording and digitization as well as the gained transcription are introduced. Next, the development of a system for automated transcription of the corpus, from collecting data, to acoustic and...
