Available Topics & Tasks

  • [Virtuality] Content Management for Virtual Climbing 2 (Bachelor Thesis, or Practicum) For our existing physical-virtual climbing environment Vreeclimber, migrate two of four existing contents to the latest Unity version and integrate them with the interaction template of the climbing wall. The contents are: climbing in an alpine environment and climbing on a volcano. Requires 3D modelling skills and a good understanding of the requirements of VR applications as a major issue will be finding the optimal trade-off between level of detail and framerate requirements of the game engine. Please note that a fully functional model of the climbing wall including motor management and tracking does exist and can be used out of the box.
  • [Multimedia] Deep FFMPEG Video Classification (Master Thesis, Bachelor Thesis, or Practicum) Implement an FFMPEG extension that is able to classify videos (films) into different categories by deep learning depending on the recording system (home HD recording, professional), type of content (film, documentary, etc.) and genre (drama, action, etc.). Due to the usage of the FFMPEG library requires good programming skills and, particularly, C++ programming experience.
  • [Multimedia] Game Design for Augmented Reality Bouldering (Bachelor Thesis, or Practicum) For our existing physical-virtual climbing environment Vreeclimber, implement two more games for bouldering with augmented reality. Pracitcally, this requires the design of targets (sprites), a recognition algorithm in OpenCV and of game designlike in the old days of level/arcade games. Required skills are Python programming, graphics design and computer vision experience. Please note that a fully functional model of the climbing wall including motor management and tracking does exist and can be used out of the box.

  • [Multimedia] Homesick Sound App (Master Thesis, Bachelor Thesis, or Practicum) Develop a mobile app that exchange the sounds created by the city you live in with the sounds of your home city. Requires implementing a server for sound upload and categorization (to be done by the app automatically in the background, classification e.g. into "traffic", "market", etc.) and of a feature-based classification app that is able to understand the current sound environment and to replace it (over earphones) with cached sounds from the place that you chose on installing the app. An example: The app should help to make someone from Mumbai feel at home in Zurich. Requires good knowledge in audio signal processing.
  • [Intelligence] Miki - Machine Intelligence for Kids (Master Thesis, Bachelor Thesis, or Practicum) Based on MIT Scratch develop blocks and procedures for machine learning that can be understood and used by kids. For example, provide blocks for face recognition based on learning, simple command/speech recognition, object tracking, etc. Requires a good overview over computer vision, audio retrieval and/or signal processing, machine learning as well as solid programming skills. This project can be implemented by 1-2 students. If done as a master thesis, requires evaluation with a test group of children.
  • [Multimedia] Mechanical Radio (Master Thesis, Bachelor Thesis, Practicum) Build a system that generates endless audio streams consisting of information on a specific topic (given in the form of keywords), general information (e.g. weather, news) and music that fits to the chosen topic. The entire system should run on an embedded computer and perform all intelligence-based tasks (selection of information and text) on the edge. The final stream should have production quality and be both informative and entertaining. If done as a master thesis, has to include an extensive user-based evaluation.

  • [Intelligence] Royal Bot the Second (Bachelor Thesis, Master Thesis or Practicum) Build a mobile robot that recognises its environment and interacts with humans, requiring the understanding and interpretation of their motives, thus developing a basic form of consciousness. The robot exists in a first version and is able to recognise the following settings (+interaction): (1) cheering crowds (stand still, look tangentially away from the crowd and slowly wave back), (2) one person kneeling in front of the bot (draw a miniature sword and knight that person). It is, hence, a jovially royal bot. Now, please extend the framework by additional features and more consciousness. For example, when recognizing groups of people in uniforms, the robot should stand erect, move slowly forward, hoist a small flag and play some sombre yet enchanting piece of music. Further requirements will be defined by the supervisor in the pre-course meeting. Please recognise that apart from the humorous requirements this is a serious topic with hard to achieve goals.
  • [Virtuality] Smartphone-based Interactive Virtual Climbing (Master Thesis) For our existing physical-virtual climbing environment Vreeclimber, implement an augmentation of the virtual environment that includes (1) the usage of smells over an existing interface (Vragrancer, as used in the Virtual Jumpcube application), (2) controlling the environment of the current climber externally (by, for example, adding birds/spiders/etc., thunderstorms, other environmental effects, etc. - whatever can be thought of) through a mobile app, and (3) the evaluation of the effect of interaction on immersion in a user study. Requires good knowledge in Unity programming, VR design and 3D modelling. Please note that a fully functional model of the climbing wall including motor management and tracking does exist and can be used out of the box.






  • [Intelligence] A Toolbox for Artificial Consciousness: Second Iteration (Bachelor Thesis, Master Thesis, or Practicum) Extend the existing Python framework for artificial consciousnes by a generalizing mechanism for the understanding of happiness and fear. Based on visual stimuli the agent should be able to generalize the notion of fear it has of dogs as well as the notion of happiness it perceives from seeing cats using reinforcement learning. Alongside, improve the simulation capabilities by a visual rendering, dynamic components and improving re-usability of components. Students of Media and Brain 1/2 are preferred.
  • [Intelligence] Transfer Learning for Image Hunters (Bachelor Thesis or Practicum) Develop a deep classifier that is able to identify strongly camouflaged animals in images. The classifier should run on an embedded system (practically, a Raspberry Pi 4; edge computing) and employ an existing object classifier that is re-trained to the specific task (transfer learning). Once recognized, the classifier should be able to determine if, in case a bullet would go through the center of the image, the animal would be killed, wounded or remain unharmed. Based on the classification result, a hash value should be computed that can be read from the edge computer via an Android mobile app and forwarded to a given REST interface. Requires good deep learning skills, experience with edge computing and a minimal knowledge of mobile app programming.
  • [Virtuality] Virtual Reality Evaluation of Robot Sonification (Master Thesis, Bachelor Thesis, or Practicum) Perform a VR-based evaluation of different forms of sonification on an existing robotics environment (robot arm, stereo cam, joystick, headphones). Requires the implementation of VR app that uses a stereo data input stream for the visualization of a robot and a ball that needs to be grabbed by the user. The app should, furthermore, provide different forms of sonification that should help the users in grabbing the ball with the robot via HMD and joystick. The hypotheses are that using sonification makes (1) the learning process faster, (2) the grabbing process faster, and (3) the grabbing process more reliable. Evaluate theses hypotheses with a small group of users.

  • [Virtuality] Virtual Climbing Applications for Children (Bachelor Thesis, or Practicum) For our existing physical-virtual climbing environment Vreeclimber, implement (one of) two contents: (1) The climbing of the side of a pirate ship and/or (2) the climbing out of the hut of a giant in a fairy tale. In the latter case, the story is that the giant sleeps in his bed in a corner of the room and the climber has to get out before it awakes. Practically, this content should be implemented in the Unity environment. The focus of the work is on as good as possible graphics design. Requires excellent skills in 3D modelling. Please note that a fully functional model of the climbing wall including motor management and tracking does exist and can be used out of the box.
  • [Multimedia] Voice Identification with an Artificial Corpus (Master Thesis, Bachelor Thesis, or Practicum) Develop an approach for the sampling of a corpus of artificial words (based on literature in form of texts/ebooks) that represents the typical distributions and combinations of phonemes in existing languages statistically correct. Should focus on the Serbian, Hungarian and Turkish languages.

Further requirements are a minimum understanding of game engines as well as readiness to improve existing physics engine procedures (e.g. for a correct implementation of the welding process). If performed as a diploma thesis, the task has to include a small sclae evaluation with test users and quantitative measurement.

  • [Virtuality] Vree Runner: Virtual Reality House Running (Bachelor Thesis, Master Thesis or Practicum) For our existing house running prototype improve the software implementation in the game engine. Tasks include more and better content (e.g. walking down a crater on the Moon or the main building of TU Wien), improve speed measurement, extend the implemented haptic elements (improve existing earthquake, add wind, spray and heat - for which the hardware exists) and add olfactory stimuli (hardware exists). If done as a diploma thesis, involves doing a user study on the levels of excitement, immersion and (hopefully not) simulator sickness. Requires good programming knowledge (ideally, in Unity) + basic 3D modelling knowledge.
  • [Virtuality] VR Motion Sickness Recognition based on Audio Analysis (Master Thesis, Bachelor Thesis, or Practicum) Implement an application that is able to recognize the physical sickness of a person in an VR environment by audio analysis. Statements such as "uh, I am feeling sick" etc. should be recognized by the system and proper countermeasures should be taken (e.g. reducing the speed of the VR application). Furthermore, statistics should be recorded, when and in which applications test subjects tend to develop motion sickness. Requires interest in media analysis and a basic understanding of audio analysis with deep neural networks.

Running Tasks

  • [Virtuality] Content Management for Virtual Climbing 1 (Bachelor Thesis) For our existing physical-virtual climbing environment Vreeclimber, migrate two of four existing contents to the latest Unity version and integrate them with the interaction template of the climbing wall. The contents are: climbing a space ship or a crater on the Moon. Requires 3D modelling skills and a good understanding of the requirements of VR applications as a major issue will be finding the optimal trade-off between level of detail and framerate requirements of the game engine. Please note that a fully functional model of the climbing wall including motor management and tracking does exist and can be used out of the box.
  • [Virtuality] Finger Tracking based on Deep Learning (Bachelor Thesis) Based on an existing prototype for hand image generation (based on 3D models of hands) develop a deep learning model that is able to recognize hand poses (fist, open hand, etc.) as fast as possible. Input images can be generated for all degrees of freedom (hand size, skin color, anomalities, etc.) and all perspectives (front, side, etc.) - thus millions of training images can be generated quickly. Training should be startet with CNN architectures, but might also include recurrent networks. For application, the model is fed with images from a consumer webcam. Goals are the maximization of the frame rate (for VR >=90fps would be desirable; 10-20fps are realistic for state-of-the-art Nvidia graphics cards) and the maximization of the accuracy (e.g. measuresd as mean average precision for five categories on the scale between open hand and fully closed fist). Requires good engineering skills and an interest in 3D modelling, VR and machine learning.

  • [Multimedia] Implementation of a Mobile Interactive Climbing App (Practicum) Climbr is a mobile app that allows for intuitive visual editing of climbing routes.

Then, you re-implement the existing app on a quality level that allows for publication in the Android and Apple app stores.
  • [Intelligence] Looking through the Fog of War (Master Thesis) Investigate how much planning makes sense in strategy games (reinforcement learning) under partial informations ("fog of war"). The idea is that for deeper exploration assumptions have to be made, which might be wrong & thus lead the exploration process into the wrong direction. Goal should be to develop a rule based on game complexity (what is that?) that limits the exploration process. For gaming experts: Please notice that this is not about the balance of exploration vs. exploitation but about the balance of vertical vs. horizontal exploration. The topic is ideally suited for students who passed VU Strategy Game Development and requires solid programming skills.

Practically, this means the implementation of content and interaction in a Unity game engine. Required skills include a basic understanding of rock climbing, experience in game design and the willingness to gather information about the measurement of training impact. If done as a diploma thesis, a limited user-based evaluation must be included. Please note that a fully functional model of the climbing wall including motor management and tracking does exist and can be used out of the box.
  • [Virtuality] Virtual Rock Climbing of Famous Routes (Bachelor Thesis) For our existing physical-virtual climbing environment Vreeclimber, implement content that simulates the climbing of at least three famous rocks. Practically, this means the implementation of content and interaction in a Unity game engine. Required skills include a basic understanding of rock climbing as well as experience in game design.
