Blockchain Technologies - various thesis opportunities - Open
Within the framework of the Fraunhofer Blockchain Laboratory and the Blockchain Real Lab, bachelor's and master's theses on applications and concepts of blockchain technology offer. Please contact us if you are interested in the subject.
Data Analysis of Micromobility in the City of Aachen - Running
This thesis focuses on the data analysis of micromobility data in Aachen. The goal is to use data science methods to gain insights from the already gathered data. To this end, a suitable data model should be defined, which then enables the analysis of both station-based, free-floating and hybrid shared mobility modes. On this defined data basis, various analyses should be performed.
An Intelligent Menu Placement System for Mixed Reality Applications - Finished
Completed by Yanxi Liu in 2021; Supervised by PD Dr. Ralf Klamma, AOR, Prof. Wolfgang Prinz, Ph.D; Advisor(s): Benedikt Hensen, M.Sc.
A common problem with spatial immersive applications is the placement of UI elements in the space. On the one hand, a menu needs to be accessible and on the other hand, it must not be in the way of the user when it is not needed. Moreover, the menus need to adapt to the room’s characteristics, e.g. to avoid problems where menus clip through walls and become unreachable. For mixed reality applications, the environment can vary from small rooms to large lecture halls. UI systems must account for this. For instance, UI elements cannot be placed in a fixed position in space without respecting the spatial mapping of the real environment. Instead, a more intelligent solution is required for positioning UI elements in space.
Immersive Curriculum and Learning Plan Visualizations in Mixed Reality - Finished
Completed by Yul Eberlein in 2021; Supervised by PD Dr. Ralf Klamma, AOR, Prof. Wolfgang Prinz, Ph.D; Advisor(s): Benedikt Hensen, M.Sc.
The creation of learning plans is a complex and important task. There are dependencies between the different topics, e.g. an advanced subject can only be understood if the underlying basic theories have been considered. Learning plans contain short-term, mid-term and long-term goals which should ideally be synchronized to each other. Additionally, learning plans bear a strategic component by identifying aspects which are most beneficial for the student’s future. There are also collaborative considerations. Members of learning groups want to adapt their learning plans to each other so that they can either learn topics together simultaneously or so that one group member who is already familiar with the topic is able to support the other group members. A framework for creating learning plans is given by Learning Design which defines clear learning outcomes, activities, times and required resources. Since learning plans are abstract, they are rarely visualized. However, such a visualization can act as a persistent overview that allows students but also lecturers to create consistent learning plans where short-term tasks work towards long-term learning outcomes. To grasp the complex nature of learning plans, a promising solution is the immersive creation of visualizations in 3D using Mixed Reality technology.
Immersive 3D Presentations for Education - Finished
Completed by Lukas Liß in 2020; Supervised by PD Dr. Ralf Klamma, AOR, Prof. Wolfgang Prinz, Ph.D; Advisor(s): Benedikt Hensen, M.Sc.
Lectures convey 2D content on slides that are projected onto a wall but the understanding of 3D structures is important in anatomy courses or engineering. Moreover, the legibility varies based on the position in the lecture hall due to the angle and distance of the viewer which can influence the learning efficiency. Mixed Reality has the ability to immerse the viewer in the presentation. Since participants can use their own hardware, e.g. smartphones, to view 3D presentations, content can be positioned individually at the optimal location for every person. Additionally, presentations can vary in scale, ranging from miniature 3D models that are displayed on the table of every member in the audience to above-life size close-ups. Lecturers can use the same 3D presentation for remote teaching if face-to-face lectures are not possible.
Persistent Association of Virtual Objects in Mixed Reality - Finished
Completed by Sebastian Meinberger in 2020; Supervised by PD Dr. Ralf Klamma, AOR, Prof. Wolfgang Prinz, Ph.D; Advisor(s): Benedikt Hensen, M.Sc.
A mixed reality environment immerses users in a three-dimensional space. This allows them to organize digital content in the entire room, e.g. task cards in immersive project management. A natural way to sort related objects is by placing them close to each other. However, this kind of spatial co-location of objects is not enough to stress their relation to each other. If another user who is unaware of the association moves one of the objects, the spatial connection is lost. Hence, lines in 3D space are required which establish a visual and persistent connection between the objects. In a previous project, an initial system was implemented which uses straight lines to connect the objects. However, straight lines have some shortcomings since they intersect with obstacles between the two endpoints. A better connection system can use 3D curves to avoid the obstacles in an efficient way.
Bachelor, Master
Distributed Activity Coordination with Constraints - Finished
In cooperative user environments the distributed coordination of activities with hard and soft constraints is a challenging task. The objective of the thesis is the development of an heuristic for distributed coordination of activities with hard and soft constraints starting with a literature research, algorithm design and simulative evaluation.
Guided Search Algorithm for the Mobility-Oriented Agenda Planning Problem - Finished
The need of mobility arises from activities such as a meeting or a doctor's appointment. Often, when planning these kinds of activities the mobility to these locations is only planned after the activity is already scheduled, which may be a sub-optimal approach. While planning it is hard to comprehend which consequences a particular action, such as moving the location or time of an activity, has on the agenda and mobility schedule. The objective of this thesis is the analysis, design, implementation and evaluation of a mobility agenda planning assistance system in form of a graphical user interface which interweaves the mobility and agenda planning processes.
Travel Assistance using Natural Language - Finished
Completed by Kajzer, Marko in 2018; Supervised by Prof. Dr. Matthias Jarke, Prof. Wolfgang Prinz, Ph.D; Advisor(s): Dr. Christian Samsel, Dr. Karl-Heinz Krempels
Previously, we developed approaches and solutions for travel assistance using e.g. a wearable device, as well as a prototype for a natural language travel information system. We'd like to combine these two approaches into a combined prototype and test it in the field.
Device Proxy Discovery and Ontology-Based Domain Model in a Distributed Application - Finished
Completed by Avila, Beatriz [Alessandra] in 2013; Supervised by Prof. Dr. Matthias Jarke, Prof. Wolfgang Prinz, Ph.D; Advisor(s): Ferry Pramudianto (Fraunhofer FIT)
This master thesis focuses on Web service discovery and the use of ontologies as centralized domain model for distributed applications.
Design Space Exploration of Ubiquitous Computing Applications using Agent-Based Simulations - Finished
Completed by Stefi, Anisa in 2012; Supervised by Prof. Dr. Matthias Jarke, Prof. Wolfgang Prinz, Ph.D; Advisor(s): Mirko Geissler (Fraunhofer FIT), Markus Valle-Klann (Fraunhofer FIT)
