Offene Themen für Abschlussarbeiten

These are some of the current topics for final theses projects in our group. Not all ideas for projects are listed here, so please get in contact if you like the general flavour of topics or if you have project ideas that fit within our area of work, and we can discuss!

Most topics can be done in German or English - please contact us for further information!

Data Physicalization

Data Physicalization is a new research area that investigates representations of data that are not purely screen-based and visual, but 'live from' being physical, maybe even touchable. These representations are called physicalizations, analogously to visualizations. This can range from small 3D-printed objects to large sculptural installations, where people have to walk around (or in) the data, and it may use various materials. See (for a long list of diverse examples) and this video

Following our semester project, we want to investigate data physicalizations in user studies to understand better how physicalization is different from visualization. Here are 3 different theses projects: 

- User study: How do people investigate a physicalization? How do they manipulate it and what gestures do they make? (compare single person vs. pair)

- Experimental User Study: Touch vs. non-touch vs. on-screen. How does the ability to touch influence understanding and memory? Does it make a difference if the object is real, in the same room to seeing it on-screen (maybe in 3D, but it is clearly virtual)? 

- The impact of scale. Build 2 or 3 different sizes of the same physicalization and assess user experience (e.g. using AttrakDiff or PANAS questionnaires) 

(The simplest for these would be to either rebuild a physicalization picked from the literature or ask a research group to send us an existing examplar for these topics – but we can also generate something new... )

Designing a soft music interface (B.Sc. / M.Sc. with more advanced development and user evaluation)

You are interested in designing novel types of music interfaces? For this thesis topic, we suggest that your novel music device should exist out of so-called soft materials - as e.g. textile-based or pneumatic interfaces. Input modalities for activating or playing sounds can work through touch mechanisms or buttons. Your application can be inspired by existing instruments of interfaces but novelty interaction is in the focus. Skills in music making might be helpful but are not necessary. Your thesis work needs some development of hardware and software components and will surely be challenging in terms of crafting and implementing soft materials for hiding technology.

Exploring Tangible Non-Screen Games with Physical Interface Props Inspired by Soft Robotics (B.Sc./M.Sc.)

Develop and implement a multiplayer interactive game that uses physicaldynamically inflatable objects/props as input/output devices and that does not rely on screen based interactions (LEDs embedded in the object and sound can be used). The goal of this thesis work is to designimplement and test prototypes of novel tangible game concepts that explore the design space and the user experience of tangible game concepts with soft and malleablehandheld interface props. The game should create engaging interactive experiences for the players without the use of a screen and support physical exertion. The game concept can be based on a (modified) existing game/sport, a new game concept or an augmented sport​. More Detail

Machine Learning for Sensor Data Analysis in Deformable Tangible Objects for HCI Applications (BSc/MSc)

The goal of this thesis work is to implement algorithms and (embedded) software to merge and interpret (real time) data from multiple sensors by using common machine learning techniques (and tricks) to robustly distinguish between different physical input gestures for tangible HCI applications. Ready-to-use electronics and sensing platforms for development will be provided as a basis for the thesis work. Soft/Flexible and inflatable objects with integrated sensors can be provided for testing. Custom inflatables with integrated electronics and sensing can be produced at the Digital Bauhaus Lab and at the Bauhaus Apparate Labor using a custom CNC controlled heat-welding machine for Nylon or TPU.​ More Detail

Mapping signals in different modalities - M.Sc (or very advanced B.Sc)

If we represent data in different modalities of representation (auditory, visual, haptic, etc), how would these different representational modalities align with each other? What haptic signal would correspond to a given auditory signal? Or to a visual representation= This theses project is to run an experiment where participants will map auditory signals to vibration levels, or colour output (or light intensity), while doing think-aloud. Besides of systematizing how people align the different signals, we want to know how people go about this talk, and their thought process.
Required skills:  user studies, systematic organisation of studies and analysis skills (potentially also basic electronic prototyping),

This will be a collaboration with Dr. Trevor Hogan at Cork Institute of Technology (for this reason ideally the studies should be conducted in English).
