When evaluating interactive applications such as web applications, mobile apps, smart IoT gadgets, etc., the interactions of the users play a crucial role. To be able to analyze these within user studies, they must be logged (e.g., by calling a URL on a study server, provided the interactive application is connected to the Internet). Later, this information becomes invaluable in research contexts.

The goal of this work is to develop an interaction logger for user studies as a web application (technology stack of your choice). The project can be conducted as a bachelor’s thesis, master’s thesis, or "Informatik Praktikum". For the latter, a concept should be developed as an interactive prototype. For a bachelor’s or master’s thesis, interviews with (professional) developers and researchers should first be conducted to determine their needs when logging in the context of user studies, and these needs should then be implemented as a prototype.

This work is suitable for students with an interest in user research and web development.

The goal of this bachelor's thesis or "Informatik Praktikum" is to create an (interactive) visualization that depicts the problem space and possibilities surrounding energy data in the development of innovative applications. In recent years, there have been intensive efforts to centralize the consumption data of energy consumers in Europe into shared data-spaces. This has led to a landscape with a variety of innovative business models and use cases.

The work is divided into two parts. First, the problem space needs to be explored. We have conducted and transcribed a series of interviews. These documents need to be evaluated, and if necessary, supplementary literature research should be conducted.
In the second step, the findings should be visualized, for example, using D3.js, although the choice of technology is ultimately up to the student.

This work is particularly suitable for students who want to dive into qualitative data analysis and then creatively explore the presentation of the results.

(For some context of Markdown, see above :-)

The plan for this topic is:

1. Develop a syntax that extends Markdown to allow for a simple, text-based description of questionnaire elements such as checkboxes, lists to choose from, percentage sliders, and free-text fields.
2. Devise a way to render such source files to HTML forms, potentially implemented as a web-based editor with live preview, and
3. Connect them with existing Web survey software such as LimeSurvey.

The topic includes a survey and comparison of existing tools and literature on (online) surveying, a usable implementation, and a qualitative evaluation with prospective users of the technology.

Pure Data is a visual language for multimedia computing. Pure Data programs, usually called "patches", may use various software engineering techniques such as modularization to achieve better readability, reusability, and maintainability. There exist some established patterns. Yet, there is little introductory literature on on them. In this project, you research the existing material such as public patches and libraries, Pure Data's own documentation system and included examples, and your own experience creating programs in this (and other) programming language(s). The outcome of the project is a set of well-documented worked examples of good software engineering practices in Pure Data.

Participation and research intervention in our current course Network-based Communication Ecosystems is possible – you are invited to include our students in your research. We can also connect you with the international community of Pure Data users and developers for further investigation.

Wireshark is a renowned measurement and analysis software for computer networks. Its dissector library is large, yet lower-layer protocols such as GARP and GVRP (protocols for configuration management between switches in LANs) are only partially implemented, do not appear to be tested, lack documentation, etc. Your task in this project is to assess the state of GARP / GVRP / GMRP protocol support in Wireshark through experiments, and extend the implementation and documentation to support the use cases that you identify as most relevant.

For this project, you will work with practical network equipment such as switches and wiretaps, as well as write software in C, and glue code in other languages.
