The project is focused on the dualband circularly polarized antenna, which is designed for receiving amateur radio frequencies income 145 and 435 MHz. First the work describes the principles of the antennas, then it focuses on the design and simulation. The antenna is simulated in the program 4nec2 and CST MICROWAVE STUDIO.
Visualization Tool for Drone Pilot in Microsoft HoloLens 2
Kyjac, Martin ; Herout, Adam (referee) ; Bambušek, Daniel (advisor)
When piloting a drone, the pilot must monitor both the drone itself and various flight data. This activity requires constant concentration and even less inattention can lead to an accident. Especially when flying at greater distances, the pilot can very easily lose track of where the drone is located, which side it is heading to, or how high it is. To verify this information, it is necessary in common applications to tilt the head and thus lose sight of the drone because this data is located on the controller, which the pilot holds in his hands. This context switching is very impractical. The goal of this application is to visualize this data using augmented reality displayed through Microsoft Hololens 2. All necessary flight data is displayed using holograms  at the exact same position where the drone itself is in the sky, so the pilot does not have to switch between contexts. It is also much easier to display various elements of the mission in this way. Normally in such cases, the pilot has to somehow interpret the data from the 2D map into reality, which can be challenging. However, with augmented reality, this data can be displayed directly into the real world.
Augmented reality and its use
Ibehej, David ; Holoubek, Tomáš (referee) ; Hůlka, Tomáš (advisor)
Augmented reality is one of the most developed technological areas. It corresponds with the fact, that we hear more and more about it and therefore it needs to be considered for the future. This bachelor thesis attempts to provide brief research in topics of its definition, history, current usage, shortcomings and options in the field of game engines and developer tools. In second part it demonstrates possible utilization in industry providing the solution of mechanical component projection and interaction.
Interaction Device for Augmented Reality
Pavlenko, Peter ; Kapinus, Michal (referee) ; Beran, Vítězslav (advisor)
This master thesis explores interactive augmented reality. The aim is to design, create andtest device, which allows interaction between user and augmented reality. First analyzesaugmented reality, devices for its displaying and necessary calibration methods. Then, onthe basis of acquired knowledge, shows design and construction of few prototypes of devicelike this. Finally it shows experiments to test correctness of the concept.
Visualization Tool for a Drone Pilot in Microsoft HoloLens 2
Václavík, Marek ; Kapinus, Michal (referee) ; Bambušek, Daniel (advisor)
Controlling a drone can feel like a difficult task. Numerous different usage possibilities, together with increasing interest there is even bigger need for advanced tools that allow user to control these robots. In many sectors, auto-pilot programs are used that provide a bit of automatization for repetitive tasks.  However, there are many situations that require manual approach of the pilot. Such person needs constant live information about the drone, its position, and surroundings. Due to these dependencies, the pilot requires reliable tool that would allow him to control the drone.      Widely used application use screen to display such information. Pilot is then forced to switch between multiple contexts and must compromise his concentration. The aim of this bachelor thesis is to explore the existing possibility of such application in augmented reality. The goal is to create an environment which would lighten the task of controlling the drone for the pilot. As the device that allows the user to work with augmented reality, this thesis introduces Microsoft Hololens 2. These glasses can display information through the developed application which is needed for controlling a drone. Needed information are displayed directly in real-time while the pilot is also aware of many other data used for completing the tasks. The aim is to reduce the disorientation of the pilot.
Portal Game for Microsoft HoloLens
Bandik, Matej ; Kapinus, Michal (referee) ; Bambušek, Daniel (advisor)
Goal of this work is to create an adaptation of computer game Portal for device Microsoft HoloLens. Required application should be able to demonstrate concept of the game in real environment. Next important requirement was to move interface of whole application to real space. The result is native application for Universal Windows Platform, which converts game mechanics and models of game Portal from computer 2D space to real 3D space. In the main part, user is set to the role of an player of logical puzzles, in which he is using gestures for manipulating with holograms or activation of several mechanics. Second part opens possibility to recreate real space by inserting virtual objects. By their logical layout, user can create different solvable puzzles directly in space, in which he is located. Created application effectively uses augmented reality and possibilities of Microsoft HoloLens device for presentation of main concept of game Portal.

Adámek, Roman ; Věchet, Stanislav (referee) ; Bastl, Michal (advisor)
This thesis deals with the design and construction of a four-wheeled mobile robot designed for an interactive exhibit and educational purposes. This robot is capable of wireless image transmission and manipulation with objects. In addition, this thesis deals with the construction of a charging station and user interface for controlling the robot which contains elements of augmented reality and minigames.
Controlling Virtual Avatar in Microsoft HoloLens with Use of Real-World Elements
Fajtová, Klaudia ; Beran, Vítězslav (referee) ; Bambušek, Daniel (advisor)
Cieľom tejto práce je štúdium skenovania a mapovania prostredia v súvislosti s rozšírenou realitou, s využitím zariadenia Microsoft HoloLens a následne vytvoriť riešenie ako dynamicky generovať virtuálny obsah, ktorý by bol schopný reagovať na dynamické zmeny prostredia. Cieľom je zber dát z reálneho prostredia pre získanie informácií o jeho zmenách, ich spracovanie a následné využitie. Za účelom dosiahnutia týchto cieľov boli použité  komponenty Microsoft HoloLens zodpovedné za priestorové vnímanie. Výsledná aplikácia obsahuje virtuálneho avatara, ktorý sa pohybuje po priestore a zbiera náhodne vygenerované ciele. Avatar je schopný reagovať na zmeny prostredia a je ovládaný pomocou hráčskeho gamepadu, ktorý je s headsetom spojený pomocou technológie Bluetooth.
Synthesis and Detection of Color Markers for Augmented Reality
Beťko, Peter ; Szentandrási, István (referee) ; Herout, Adam (advisor)
This master's thesis emerges from the research in the field of uniform marker fields for augmented reality and broadens it by the possibility of generating colored marker fields based on arbitrary pictures. The thesis describes basics of augmented reality and explains the ideas from the Uniform Marker Fields paper. Presented is a program for generating colored marker fields as well as a tool for detecting markers and evaluating success rate of the detection. In addition, the work proposes a study of color constancy in the process of printing and recording. This study exceeds the scope of the requirements for this master's thesis; the knowledge can be used in arbitrary applications that use colors to code information. Finally, the integration of the knowledge into the marker field generating algorithm and resulting improvement of detection success rate are discussed.
Helmet for Virtual and Augmented Reality
Buš, Ondřej ; Přinosil, Jiří (referee) ; Říha, Kamil (advisor)
The thesis focuses on the construction of a functional headset for multimedia content consumption. The acquired theoretical knowledge was used in the design and construction of the resulting headset. The theoretical knowledge was consolidated and extended by practical tests on currently available commercial AR/VR headset solutions. In the practical design, increased effort was made to keep the resulting solution as simple as possible. The components that were used in the work can be obtained relatively easily via the internet. With the help of advanced techniques, the thesis tries to optimize the visual experience. The most suitable parameters of the optical lenses are selected. The optical system is enhanced to provide an extended horizontal field of view. The thesis discusses the fabrication of the headset using the 3D printing method on a 3D printer. Subsequently, the individual parts are assembled into a single functional unit. The result of the thesis is a working prototype headset suitable for multimedia content consumption.
