Ongoing theses

Anas Alnayef: Autonomous Pneumatic Tangible Displays

Cooperation with Prof. Hornecker, HCI

This thesis investigates automated collection of health and activity data from users for display on a tangible pneumatic interface, e.g. via a pedometer connected to the home network which has also the pneumatic system connected as an IoT device. The users' data is automatically synced when physically present in the same network as the pneumatic system. We will also investigate using a Proportional Integral Derivative (PID) controller to make the system regulate the inflatables based on activity level of users. Based on this platform, we will then conduct a user evaluation regarding how multiple sensory channels provide a feedback to users.

Jyotsna Gorle: TrueNews v2

Cooperation with Prof. Lucks, Security

TrueNews is an approach to automatically collect cryptographic signatures from nearby smartphones to verify the authenticity of pictures taken via timestamps and geolocation (see also In this thesis, the concept will be evaluated both theoretically and practically, and should be extended to implement automatic key signatures. (Prior knowledge in cryptography is strongly recommended.)

N.N.: Designing an Open-Source Particulate Matter Sensor

Cooperation with Dr. Wimmer, Universität Regensburg

Projects such as try to enable "citizen science" by providing open-source build instructions for air quality monitoring devices, allowing everyone to provide environmental measurements for their own neighbourhood. In this project, an alternative sensor for analysing particulate matter in the air will be developed which does not only provide particle counts, but also estimates about the individual particle types. Using a "lensless imager" as described in may be an option for implementing this project.

Yorrick Sieler-Morzuch & Joachim Billert: Open Mixed Reality HMD

Cooperation with Prof. Rodehorst, Computer Vision

Recent developments in single-board computers (Raspberry Pi etc.) and displays have made it possible to build a virtual reality headset (HMD, head-mounted display) from the ground up. The goal of this project is to design and prototype a self-contained stereo video see-through HMD, based on a NanoPi M4, dual cameras, a suitable OLED display, and a 3D-printed frame.

Theresa Tobollik: Realtime Blood Oxygen Monitoring for Seizure Patients

Medical research hypothesizes that a decreasing level of blood oxygen may be a predictor for some types of seizures. In this thesis, a commercial smartwatch with O²-montoring capability is used for a longitudinal study of blood oxygen content in affected individuals.

Max Margraf: BumpCast

The previous ShakeCast and ShakeTrack projects investigated how acceleration data recorded during a handshake with wrist- and finger-mounted sensors can be used to create a secure ad-hoc peer-to-peer connection between the participants. In this follow-up project, we will investigate how machine learning techniques such as siamese networks (cf. can be used to identify matching acceleration signals from a bump or shake interaction with regular mobile devices.

Emre Ertem: LoRaWan Exploration

This project will explore how the LoRaWan-based ( Things Network ( can be used to support IoT applications in Weimar and the surrounding area by setting up a persistent gateway in Weimar and exploring potential application scenarios such as forest fire early-warning systems.

Completed theses

Erich Flock: Train & Touch

Many people use devices such as treadmills, elliptical trainers or spinning bikes to keep fit. Unfortunately, due to their stationary nature, using them can quickly become boring. Using a tablet or other touch device during use, however, is very difficult due to constant user motion. In this project, we will evaluate methods to enable the user to better interact with touch devices during training.

The impact and importance of Bluetooth Low Energy (BTLE) has been increasing more and more in the past years. It is one basic technology of the "Internet of Things". Unfortunately, even the development of simple BTLE applications requires a lot of programming. simpLE reduces the necessary workload and enables a faster and more simple development.

Goran Kosutic: Implementing GISpL in JavaScript

The GISpL gesture specification language for easy creation of multi-touch and tangible interfaces does not yet offer native support for browser-based HTML5 interfaces. The goal of this thesis is to port the existing C++ implementation to Javascript and evaluate the resulting JS library with other developers. Details about the language can be found on

Joshua Reibert: Don't SLAM your head

Virtual reality is becoming affordable thanks to powerful smartphones and suitable head-mounts. However, moving in the VR environment still poses a problem - either the user is seated and uses a joystick, often leading to motion sickness, or a wide empty space is required to avoid collision with real-world obstacles. In this thesis, a hybrid visualization of real-world environment data collected with the smartphone's camera and the virtual environment is developed. This involves porting an existing SLAM algorithm to Android. The option of merging SLAM data from several smartphones also exists for a master's thesis.
