Converted two AR/VR training demos from Unity into Unreal Engine to take advantage of photorealistic digital humans (MetaHuman). Applications deployed on Oculus Quest 2 and Magic Leap.

Created an Android camera app for visually impaired patients using AR glasses. Applied signal processing algorithms for real-time image enhancement (improve image sharpness and contrast). Used Android Studio debugging tools to improve performance on AR device.

Developed a tracking solution using embedded systems (ESP32 + IMUs) to detect walking in AR/VR environments. Used UDP to transfer inertial sensor data to AR/VR applications.

Maintained website (debugging and bug fixing in big code base) and developed new features used by students, teachers, researchers and administrators (agile software development).

Communicated with clients and defined project tasks to be implemented

Wrote unit tests and documentations for developed features

Participated in the development of the TU Wien COVID Greenpass app, which is used by all students, teachers, researchers and university staff to prove that they are either vaccinated, tested or recovered before entering university buildings. I worked mostly on the front-end side and later made changes on the back-end side.

Improved the way thesis topics are created in TISS, by giving the user the option of adding additional meta data information to the thesis topic. Improved thesis topics search, to enable users (like students) the option of searching for thesis topics using the added meta data information. I worked on both the front-end and back-end side.

Added REST-API calls for fetching examinations dates using certain parameters.

Designed and implemented a tracking system (using 8 VIVE trackers) to achieve accurate correspondence between the tiltable and rotatable physical climbing wall and the virtual world. Implemented a calibration procedure to first identify the VIVE trackers and assign them their respective roles at runtime and then align the virtual world to the physical world. Implemented a correction algorithm to ensure that the physical climbing wall and virtual climbing wall are always aligned (minimizing vertical error) when the physical wall is rotating.

Developed a Unity template project for the Vreeclimber with extensive documentation to be used by future students who want to create their own contents for the Vreeclimber project. Assisted and advised three different students with their capstone projects who used the template to create their own games for the Vreeclimber.

Developed a game using Python for the Vreeboulder Projection System, where climbers play 2D arcade games projected on the physical Vreeclimber wall (without VR equipment). In the game I worked on, the climber has to touch one or two projected game targets while the climbing wall is rotating. I used OpenPose and OpenCV to detect the climbers’ limbs via webcam and detect when the climber touches the targets.
