Shadow robot: manipulation of a robot model in augmented reality
Halenár, Timotej ; Bambušek, Daniel (referee) ; Materna, Zdeněk (advisor)
Bakalárska práca sa zaoberá manipuláciou s modelom robota v rozšírenej realite za využitia aplikácie pre tablet. Riešenie rozširuje možnosti interakcie v existujúcej aplikácii na vizuálne programovanie robotov -- AREditor. Užívateľ potrebuje pri programovaní v AREditore nastaviť pózu robota, aby mohol definovať body v priestore, na ktoré sa má robot dostať pri vykonávaní programu. Stávajúce riešenie v aplikácii umožňuje iba krokovať fyzického robota po malých inkrementoch pozdĺž osí, čo je nedostatočné pre väčšinu účelov. Hlavným cieľom práce je navrhnúť a implementovať systém, pomocou ktoréhu bude užívateľ schopný rýchlo a jednoducho nastaviť pózu modelu robota, ktorý je premietnutý na obrazovke cez skutočného robota. Užívateľ najskôr ľubovoľne nastaví pózu modelu robota, a následne pošle príkaz skutočnému robotovi, aby zvolenú pózu skopíroval. V riešení bolo využité 3D gizmo, ktorého polohu sleduje koncový bod robotického ramena. Gizmo je možné presúvať v priestore za využitia kamery tabletu a rozšírenej reality, a jeho pohyb je možné obmedziť na jednotlivé osi či roviny v priestore. Riešenie poskytuje možnosť ovládať citlivosť, s akou hýbeme bodom v priestore, možnosť zmeniť súradnicový systém, a samostatné ovládanie pre vzdialenosť gizma od tabletu. Vytvorené riešenie ponúka pohodlnejší spôsob, akým sa dá nastaviť poloha robota, a môže zefektívniť proces programovania.

Interaction with a Collaborative Robot using Augmented Reality
Zmrzlý, Daniel ; Milet, Tomáš (referee) ; Bambušek, Daniel (advisor)
This thesis focuses on the implementation of the possibility of interaction with a collaborative robot using Microsoft HoloLens 2 technology in an augmented reality environment. The work builds on the existing AREditor solution for tablet devices and adds the missing AREditor functionality to Microsoft HoloLens 2 glasses. Using these glasses and the ARCOR2 framework, it is possible to manipulate the physical robot and its model. In the initial phase of the implementation, several approaches were proposed for the user to interact with the robot, and then the solution with the most positive response was selected. The final solution succumbed to user experiments where participants evaluated the usability and compared the final solution of the two AREditors.

Evaluation of stress reaction to stimuli induced by virtual reality
Mang, Robert ; Králík, Martin (referee) ; Mézl, Martin (advisor)
This bachelor thesis focuses on the assessment of stress response to stimuli evoked in a virtual reality environment. In the theoretical part, it discusses the history of VR, the difference between VR and augmented reality (AR), VR hardware and its use in medicine. It also discusses in detail physiological parameters such as ECG, respiration, electrodermal activity and pressure plateau, which are very useful parameters in the assessment of stress responses. The results are supplemented by a questionnaire survey. The practical part proposes and describes the conduct of a research project to measure the stress response in a group of twenty volunteers. The data obtained are subsequently analyzed and statistically evaluated. Based on the discussion, the stress response is then confirmed for the parameters - heart rate and skin conductance level in the given phases. The results from the pressure platform are analyzed on only one sample participant. The STAI type questionnaire used did not show an increase in subjective stress.

Visualization Tool for a Drone Pilot in HoloLens Headset
Komárek, Jakub ; Beran, Vítězslav (referee) ; Bambušek, Daniel (advisor)
The aim of this thesis is the creation of a modern tool to facilitate the operation of drones, especially in professional sphere. The tool created by the author aims to facilitate the planning routine of the usual missions drones and help in its safe execution. The tool was also created with regard to the legislative restrictions on drone operations and contributes to their correct compliance. The author has addressed the issue with the help of a client-server application created in an augmented reality environment in HoloLens 2. The assistance in piloting is to be provided by a "heads up display" component that moves along with the drone and displays flight variables around it along with the video feed from the drone's camera. To facilitate mission planning, a 3D mini-map is implemented that provides information about the planned mission is projected onto the world around the pilot. The thesis is experimental in nature and has to determine the applicability of augmented reality in the professional operation of the drone. The results of the work are evaluated from data collected during extensive user testing, which included Comparison of the existing Litchi application with the developed application in the prepared test environment scenarios. The results showed that the interface is usable and can compete reasonably current conventional solutions. In some aspects the existing interface outperforms.

Head-Mounted Display or Tablet? Device Usability in the Context of Programming Robotic Workplaces
Kníže, Josef ; Milet, Tomáš (referee) ; Bambušek, Daniel (advisor)
This thesis focuses on usability comparison of head-mounted display Microsoft HoloLens 2 and tablet in context of programming robotic workplace using augmented reality. The existing interfaces for these devices are analyzed, and a user experiment was designed and conducted to compare them, involving a total of 18 participants who tested and evaluated both devices in two iterations. Based on feedback from the first iteration, many changes were proposed and implemented in the HoloLens 2 interface. Key changes included porting the entire application to newest framework for mixed reality, programming through scene interaction, reworking robot placements, and adding parameter configuration and action placement through the robot. The new version of the interface was tested in the second iteration of experiments, revealing that users are 32,3 % faster when using HoloLens 2 and they rate usability and user experience better compared to tablet. Surprisingly, there was no significant difference measured in user mental or physical load between the devices.

Time capsule
Ryzhakova, Margarita ; Zálešák, Jan (referee) ; Ondrík, Jozef (advisor)
The bachelor thesis deals with the topic of time capsules as a way of preserving the present and communicating with a future. Through the examination of existing time capsules in various contexts, the author attempts to redefine the boundaries of the time capsule concept. The observations also include cases where the content meets the criteria of a time capsule but is not perceived as such objectively. The author applies this exploration to subjectively define the concept to create a personal time capsule in a new media form, aiming to contribute to the discussion on the conception of time capsule boundaries. The created time capsule is a digital installation in augmented reality that people can view from posters displayed in public spaces.
