For mixed reality applications, developers usually choose a modular development approach where the application-logic is segmented into separate components which only realize one feature. In well-designed projects, the components are reusable in different contexts within the project but also outside of it. Additionally, code from these projects can be used to find examples how to ...
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 ...
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 ...
A challenge of existing educational Mixed Reality applications concerns the difficult accessibility of technology for students. Many applications require expensive head-mounted displays or high-end smartphones which can only be tried by students at the university for a limited amount of time. However, Mixed Reality content can also be shown on a broader range of devices ...
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 ...
Courses in higher education, e.g. at universities, face a challenge regarding scalability. Ideally, every student should be able to contact a mentor to benefit from the mentor’s experience and to reach the learning goals. However, if the number of participants in a course rises, the limited resources of the institution are quickly exhausted. This leads ...
Mixed reality provides many opportunities for learning applications in formal and informal education. In previous projects, we created different learning applications for various use cases. The applications target technologies like the Microsoft HoloLens, HTC Vive, Oculus Quest 2 and smartphones. Initial pilot evaluations of these applications have already been conducted. However, we would like to ...
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 ...
Existing Virtual Learning Environments like Moodle include different multi-media modules to allow lecturers to convey the learning material in a suitable way. However, Virtual Learning Environments have not yet adapted Mixed Reality technology despite its large potential to support learning processes.
Collaboration and group work are essential parts of learning since they encourage students to exchange ideas, to learn from each other and to support each other. The ability to work as a team increases the quality and amount of results and is therefore a highly demanded soft skill. However, students who face group work in ...
The goal of this master thesis is to re-design and extend an existing serious games platform as microservices for a gamification framework already realized as microservice architecture.
Our approach is a comprehensive and evolutionary sociotechnological learning analytics and design process leading to a flexible infrastructure where professional communities can co-create their wearable enhanced learning solution.
Mixed reality agents have a large potential for mixed reality learning applications, e.g. by providing a natural user interface to a chatbot or as a tutor who can demonstrate practical actions and guide the user through a complex environment. When creating such a virtual agent, one challenge concerns the scalability of interactions with the environment. ...
Online social networks (OSNs) have become one of the main types of online applications enabling the exchange of information between a large number of users, which, however, at the same time raises new security and privacy concerns. Unexpectedly for many users, automated accounts, known as social bots, are increasingly contributing to the information distribution process. ...
Research in the domain of model-driven Web engineering is mostly targeted at professional Web developers. But recent developments in Web engineering techniques more and more bear the potential to include also non-technical stakeholders into the conceptual modeling of Web applications. This new approach of integrating a complete community into the modeling process bears new challenges ...
Social Bots (software robots) are computer algorithms that automatically produce content and interact with humans on social media. This thesis will utilize chat interfaces and a social bot framework to create social bots. It will also extend the framework to support various social bot types (e.g. chatbots, crawlers, transactional bots or informational bots).
Recent developments show a rise in popularity of Learning Management Systems in an increasingly digital teaching enviroment. However, students can encounter difficulties with sustained motivation without extrinsic influences like communicating with peers. The application of gamification principles to the digital learning process provides motivating factors for students to aid their learning process. Participation in educational ...
Social Bots (software robots) are computer algorithms that automatically produce content and interact with humans on social media. The goal of this study is to discover success factors that make the use of a (chat)bot successful.
Learning Analytics Research has shown that learner facing dashboards support self-regulation. Learners gain a better understanding of their learning activities and plan further activities more conscious. This leads to higher motivation and achievement.
Social Bots (software robots) are computer algorithms that automatically produce content and interact with humans on social media. This thesis will utilize bots in learning management systems (LMSs) and aims to assist students during their course.
Nowadays, agile development processes use cloud container orchestration platforms for continuous integration, deployment and delivery. Technologies like Docker and Kubernetes are used here as the state-of-the-art cloud-native infrastructures the software is deployed on. However, deployment of heterogeneous service environments, developed by multiple teams with different technical proficiency levels, is not a trivial task. The thesis ...
