Security Analysis of Immersive Virtual Reality and Its Implications
Vondráček, Martin ; Ryšavý, Ondřej (oponent) ; Pluskal, Jan (vedoucí práce)
Immersive virtual reality is currently used not only for entertainment but also for work and social interaction where user's privacy and confidentiality of the information has a high priority. Unfortunately, security measures applied by software vendors are often not sufficient. This thesis delivers an extensive security analysis of a popular VR application Bigscreen which has more than 500,000 users. Techniques of network traffic analysis, penetration testing, reverse engineering, and even application crippling were utilised. Research led to a discovery of critical vulnerabilities directly exposing the privacy of the users and allowing the attacker to take full control of a victim's computer. Found security flaws allowed distribution of malware and creation of a botnet using a computer worm spreading in virtual environments. A novel VR cyber attack Man-in-the-Room was implemented. Furthermore, a security vulnerability in the Unity engine was discovered. Carried out responsible disclosure has helped to mitigate the risks for more than half a million Bigscreen users and all affected Unity applications worldwide.

User Interface for ARTable and Microsoft Hololens
Bambušek, Daniel ; Španěl, Michal (oponent) ; Kapinus, Michal (vedoucí práce)
This thesis focuses on usability of mixed reality head-mounted display - Microsoft HoloLens - in a human-robot collaborative workspace - the ARTable. Use of the headset is demonstrated by created user interface which helps regular workers to better and faster understand the ARTable system. It allows to spatially visualize learned programs, without the necessity to run the robot itself. The user is guided by 3D animation of individual programs and by device voice, which helps him to get a clear idea of what will happen if he runs the program directly on the robot. The solution also provides interactive guidance for the user when programming the robot. Using mixed reality displays also enables to visualize valuable spatial information, such as robot perception.

Interakce robota s virtuálními objekty
Fisla, Jakub ; Španěl, Michal (oponent) ; Materna, Zdeněk (vedoucí práce)
Cílem této bakalářské práce bylo vytvoření aplikace pro robotický operační systém ROS, přidávající virtuální objekty do dat poskytovaných senzory robota. V teoretické části analyzuje techniky simulace kombinující reálne naměřená data s daty uměle generovanými a skoumá prostředky na snímaní těchto dat. S ohledem na platformu ROS navrhuje strukturu možné realizace aplikace a následne popisuje implementaci vytvořené aplikace. Závěrem se soustředí na testování vytvořeného řešení a zamýšlí se nad možnostmi dalšího budoucího rozšíření.
