Problem Statement

Rendering the user’s body in virtual reality increases immersion and presence – the illusion of ‘being there’. Recent technology enables determining the pose and position of the body to render them accordingly while interacting within the virtual environment. However, it is unclear how users perceive different avatar styles. Additionally, how any manipulation in the avatars representation would influence the users’ states. In this thesis, we aim to explore the influencing factors of avatar perception.

Effizienz ist ein wichtiger Faktor der Usabilityforschung. Im Allgemeinen beschreibt die Effizienz eines Systems den Aufwand, welchen ein Nutzer erbringen muss, um eine bestimmte Aufgabe zu erfüllen. Effizienz wird meist in Zeit gemessen und evaluiert.

Die wissensbasierte Authentifizierung (bspw. PIN) stellt ein Beispiel für eine solche Aufgabe dar. Als Maß der Effizienz dient hier in der Regel die Zeit, welche für die korrekte Eingabe eines Passwortes/PIN benötigt wird. Neue Erkenntnisse deuten jedoch darauf hin, dass es neben der aktiven Eingabe weitere Phasen gibt, welche sowohl die gemessene als auch die gefühlte Effizienz des Mechanismus beeinflussen. Dabei ist neben der reinen Existenz dieser Phasen auch das Verhältnis der Phasen zueinander maßgebend für die User Experience.

In diesem Einzelpraktikum soll der Einfluss der verschiedenen Authentifizierungsphasen auf die Effizienz untersucht werden. Dafür sollen mehrere Modifikationen eines PIN-Eingabesystems entwickelt und im Feldtest studiert werden.

Aufgaben:

1. Literaturrecherche / selbstständiges Aneignen von Fachwissen
2. Ausarbeitung der zu testenden Konzepte (im Team)
3. Entwicklung der Studiensoftware (Android oder iOS)
4. Planung und Durchführung der Nutzerstudie (im Team)
5. Analyse und Aufbereitung der Studienergebnisse

Bei Erfolg des Projektes besteht die Möglichkeit an einer internationalen Publikation mitzuwirken.

Description

VR research prominently focuses on making virtual experiences as natural and realistic as possible. However, VR also provides ideal opportunities to create experiences where users are challenged in creative ways, both physically and mentally. Imagine, for instance, attempting to avoid objects in VR, while the HMD viewport moves in the opposite direction relative to the user's real-world movement.

The aim of this project is to investigate the user experience of various virtual challenges, where the challenge arises from mismatches between the user's virtual and real-world movements. Another consideration is whether such mismatches could be used as a teaching/awareness tool, for example, to experience physical disabilities or altered states such as intoxication.

Tasks

• Literature review: charting existing research on mismatches between real and virtual movement
• Design and implementation of several distorted ways to move and interact in VR
• Implementation of virtual tasks and challenges
• Design and conduction of a user study

Requirements

• Interest in virtual reality
• Interest in performing user studies
• Good programming skills
• Prior experience with VR technologies (Unity, SteamVR) is considered an asset

Description

Mid-air gestures enable new and exciting ways of interacting with technology, especially because devices can be interacted with from a distance. Typically, gesturing follows the pointing metaphor, wherein one or both arms are extended to point towards the device, e.g., a display. However, a persistent problem is the expressive and novel nature of the interaction: users may feel uncomfortable gesturing in places wherein they receive unwanted attention. Additionally, prolonged gesturing can lead to fatigue.

The aim of this project is to investigate new approaches to gestural interaction that could make the interaction less visible and less tiresome. In particular, the aim is to investigate gestures that are carried out by holding the arm against the body, instead of reaching out with the arm.

Tasks

• Designing and implementing the overall logic for on-body gestures
• Implementing a prototype public display application
• Designing and conducting a user study

Requirements

• Interest in novel interaction techniques
• Interest in performing user studies
• Good programming skills

Description

VR research prominently focuses on making virtual experiences as natural and realistic as possible. However, VR also provides users with capabilities they don't have in the real world, such as observing their surroundings outside of their normal viewpoint.

The aim of this project is to investigate whether enabling VR users to switch between their own and another user's viewport can enhance certain collaborative scenarios, how this affects the user experience, and what potential opportunities and challenges arise from viewport switching.

Tasks

• Literature review: charting existing research on viewport switching and out-of-body experiences
• Design and implementation of one ore more ways to switch between viewports in VR
• Implementation of virtual collaborative tasks
• Design and conduction of a user study

Requirements

• Interest in virtual reality, in particular collaborative and/or social aspects of VR
• Interest in performing user studies
• Good programming skills
• Prior experience with VR technologies (Unity, SteamVR) is considered an asset

Voll immersive Head-Mounted Displays (HMDs) wie die Oculus Rift oder die HTC Vive ermöglichen ein direktes Erleben digitaler Daten. Virtuell kann man unter Verwendung dieser Technologien an Orte reisen, die weit entfernt sind, zerstörte Städte als digitale Replikaten erkunden oder Technologien wie den ein Mondfahrzeug erleben. Das deutsche Museum nutzt Virtual Reality um in ihrer Ausstellung den Besucher Dinge zugänglich zu machen. So kann man dort Exponate in ihrem ursprünglichen Kontext erleben, wie etwa die Flugmaschine von Lindbergh.Eine besondere Herausforderung die sich im Museumsalltag ergibt ist der Betrieb des Systems im Zusammen spiel mit den Benutzern. Die internationalen Besucher aller Altersklassen bilden dabei eine sehr diverse Gruppe aus oft naiven Nutzern gegenüber VR Technologie. Die für Museumsinstallationen verfügbaren HMDs stammen aus dem Konsumerbereich und haben den Nachteil, dass sie rein technologisch für Heimanwendungen entwickelt wurden. Zudem ist der Dauerbetreib von HMDs für hohe Besucherzahlen eine Herausforderung, die in den letzten Jahrzehnten Entwicklung von HMD basierten Systemen keine Rolle gespielt hat.Die ausgeschriebene Masterarbeit besteht daher aus drei Teilen.Im ersten Teil wirst du in Zusammenarbeit mit dem deutschen Museum das Nutzererlebnis ind er aktuellen Ausstellung analysieren. Als Grundlage dienen hier für Methoden die aus der Forschung zu Public Displays. Besonders wichtig ist dabei die Analyse nicht auf die Zeit in VR zu begrenzen. Der Nutzerstrom an einer solchen Installaion beginnt mit dem Moment in dem der Nutzer auf das System aufmerksam wird und endet nach der Nutzung des HMDs, wenn der Kunde sein Erlebnis an andere kommuniziert. Dieser Ergebnisse sollen mit einer Literaturrecherche zu Methoden und Gestaltungsrichtlinien von öffentlichen Installationen verbunden werden. Das Ergebnis dieser Analyse ist eine Kategorisierung der Probleme und deren Priorisierung.Im zweiten Teil wirst du zu den erkannten Herausforderungen neuartige Lösungskonzepte erarbeiten. Hierbei können deine Interessen und Fähigkeiten einen wichtigen Einfluss auf das Ergebnis nehmen.

Description

Mesh simplification intends to preserve the visual appearance of a 3D model while reducing its number of faces. Due to the rise of mobile computing and VR applications, mesh simplification becomes a critical phase in 3D modeling for reducing the rendering complexity of a model. A 3D model designer initially starts with a high-quality model and then simplify its faces using modern 3D software, such as Blender, Maya and etc.

However, aggressively using mesh simplification function in the software quickly leads to visible defects, for instance, holes in the grid, jagged edge, and other similar errors. Thereby a designer must carefully dealing with these result and sometimes manually fix these errors.

In this thesis, you will perform user-centered research to investigate elicitation process, uncertainty and ambiguity of human preferences while mesh simplification in 3D modeling.

Tasks

You should:

• Conduct extensive literature review regarding 3D modeling, human preferences, mesh simplification, and other related fields
• Be able to understand the fundamental ideas of existing mesh simplification functions in industrial software
• Design appropriate user studies and corresponding evaluation strategies or benchmarks separately for general users and expert designers
• Use existing or develop (if necessary) 3D program(s) to conduct the designed user studies
• Perform well-structured evaluation and summarizing all outcomes in a written thesis

Requirements

• Interest in 3D geometric modeling with a background in related software and a programming language
• Understanding the basics of human-computer interaction research approaches
• Concept development and designing appropriate user studies
• Independent scientific work, creative problem solving

Note that the thesis initially starts with biweekly meetings for literature and development discussion in the first two or three monthsand then switch to weekly meeting for user study and result evaluation discussion.

Problem Statement

A stylus allows designers and artists to provide artistic digital designs. Modern tablets (Surface Pro, IPad) support a stylus, allowing users to design anywhere.

However, creating 3D models can be difficult on 2D displays. 3D modelling requires users to navigate a lot in 3D space - even for drawing simple 3D lines. This project investigates how this process can be more efficient. The idea of this project is to better merge the two processes of navigation and creation.

In this project, the goal is to explore new methods of 3D input in 2D design applications, by using both stylus and multitouch input of the user. The two main work-tasks will be 1) creating a basic drawing prototype with new interaction methods, and 2) to explore what kind of new interactions are possible.

Tasks

• Survey of related work
• Conceptual design of methods that allow users drawing of 3D sketches
• Design and implement a drawing application that integrates the methods
• Evaluation of the application in a user study
• Report of the project into the thesis

Preferred (but not necessary) qualification

• Knowledge in the area of human computer interaction
• Interest in design, drawing, and artistry
• Experience in programming of 2D/3D GUI (E.g., Java processing)

Problem Statement

Companies such as Oculus, Apple, or Microsoft are working on AR devices that may become an integral part in the daily life of the future. How the user interface may look like is still an open question, it may involve novel methods of input. In this project, we explore the use of eyes for interaction with the digital augmented information. How can the eyes be utilised to interact with digital information that are laid over the real world?

In general eye based interaction has been long investigated in the field of human-computer interaction. The eyes are one of the fastest input modalities, and work in unity with the user’s hands. Future AR devices, through glasses, have a high potential to have eye-tracking integrated and it is therefore imaginable that the eyes play an integral part in the interaction with the augmented reality.

The project is exploratory, and strongly focuses on the interaction design and building of prototypes. It involves iterative prototyping from basic ideas to mature user interfaces with close feedback rounds with the team (e.g., 1 or 2 times per week). It is also possible to get hands-on support on the implementation from team members. Ideas can be generated quickly with the team, and evaluated quickly with small prototypes. The goal is to create the most dynamic, fastest, and world-class user interface for AR. Inspirations can come from various media, e.g. Minority Report, IronMan, or Ready Player One.

Tasks

• Comprehensive survey of related work
• Setup of an AR device with integrated eye tracker (e.g., Hololens)
• Iterative development of the interaction concepts (with the team) and software prototypes (Unity c-sharp)
• Evaluation of final prototypes
• Analysis and report of study design

Preferred qualifications

• Interest UI design and Unity programming
• Scientific work and UI research
• Interest in novel input modalities and devices

Problem Statement

Virtual Reality is gaining more and more importance in our daily lives as we allow ourselves to be immersed in a simulated environment. Among its many useful application, VR can be used to carry out meetings among group of people or even be used in E-learning where the participants can be aided. Gatherings can also extend to examples such as 'Skype Session with family', 'Gathering with friends' etc. During such group meetings, where the environment is essentially a multi user environment involving interaction between participants, it is important that each participant can be completely immersed in the environment and for that, interaction and visualization techniques need to be developed. The aim of the thesis is to explore the interaction and visualization techniques for social gatherings.

Tasks

• Comprehensive survey of related work
• Get familiar with hardware and software
• Conceptual design of interaction and visual techniques between avatars that enhance the virtual immersion
• Carry out a initial survey using 'Oculus Go' to determine the necessary interaction features for enhancement
• Implementation of the design which successfully integrates the various interface design to enhance group communication in VR
• Evaluation of the design through a user study

Preferred (but not necessary) qualification

• Knowledge and interest about VR
• Able to work independently
• Unity Programming

Tasks:

• Development of interaction concepts for the handling of AI/generative systems in a musical context.
• Implementation of a functional prototype that demonstrates the basic concept.
• Conducting a study with students.

Requirements:

• Interest and experience in music theory.

User interfaces facilitate interaction with digital content. Concepts such as "Undo" make it possible to reverse actions that did not have the desired effect. But what would interfaces and the corresponding interactions look like if irreversible actions were central components of interaction design? In this thesis a design exploration should be performed that focusses on materials like paper which affordances lead to actions such as tearing, crumpling, folding, punching holes, etc.. How can familiar concepts such as punch cards or origami help to design intelligible interaction metaphors, that create commitment to the actions we as users perform with technology? What impact will such concepts have on prospective actions?

Description

Developing an Android app for predicting personality traits via smartphone usage

In the PhoneStudy project, an interdisciplinary team consisting of psychologists, statisticians, and computer scientists develop an Android app, which tracks and logs the user’s smartphone behaviour to predict personality traits. For example, we track the number of users’ calls, sms, and app usage, which might predict how extraverted the user is. The app will be distributed among participants in spring 2018, which will then use the app for several months. There are several tasks for media informatics students in this project (cf. below), from which you can choose. Please contact me when you are interested in the project and will give you more details.

Tasks

• Configuring and working on the server, its scalability and stability, as well as the data base (MariaDB)
• Working on the internal web based front end of the server, which depicts the current status of participants and logged data
• Further develop the app: integrating new features and fixing current bug
• Quality management: Developing automatic testing scripts

Minimum requirements

• Interested in interdisciplinary projects
• High communication skills, especially willing to communicate interdisciplinary
• Able to work independently
• Previous experience with server configuration, (Android) app development, web development, data bases (depending on the chosen task)
• High frustration tolerance

Description

Tasks

• Conduct an extensive survey of related research with a focus on personality assessment and attitude towards data sharing.
• Design a suitable online survey based on previous research to collect coping strategies
• Recruit n = 300 participants, who fill out the online survey
• Evaluate the findings using qualitative and quantitative research analysis methods.

Rodeghero et al. have used eye tracking to investigate what aspects of source code developers looktowards for understanding a code base. Their work, however, was focused on traditional software development using imperative programming languages.

With data-driven as a new, growing development paradigm, many of the researchin traditional software engineering has to stand up to the questions whether it applies to this paradigm as well.

In this thesis you will address this question by:

• Perform a literature analysis
• Replicating the original study for traditional software development
• Extend it by performing the study in a Machine Learning context
• Compare the results of the two studies
• Writing a thesis and presenting your results to an audience
• (Optional) co-writing a research paper

You need:

• Strong communication skills in german and/or english
• General knowledge of how to perform a user study
• General knowledge of statistical evaluation of research results

Maintaining an overview of large software projects can be hard.Large modules, complex dependencies, sub-projects etc. are hardto comprehend on first glance.
An established method to cope with complex hierarchies areinterfaces with semantic zoom.

In this thesis you will explore how semantic zoom and zoomableuser interfaces (ZUIs) can be used to improve software engineering.After analyzing existing work, you will create a prototype, which youwill evaluate in a user study.

Your work consists of:

• literature review on ZUIs, software engineering tools
• designing and implementing a prototype of a ZUI for software engineering
• evaluating the user interface in a user study
• writing a thesis and presenting your results to an audience

You need:

• Strong communication skills in english
• Experience with User Interface design
• A good understanding of software architecture, design, and engineering
• Good knowledge of user testing methods

StackOverflow is a knowledge-sharing platform for software developers of all sorts of disciplines. For more traditionaldevelopment paradigms, the Q&A structure is straight forward, since minimal examplescan easily be posted. In the world of Machine Learning and Big Data, this is not so trivial, since many problems are inherent in the data. Sharing data is unfeasiblefor reasons of size, privacy, etc., making it harder to provide approrpiate contextfor the Q&A setting.

In this thesis you will analyze the situation by:

• Perform a literature review
• Collect and classify a sample of StackOverflow threads using the methods from Grounded Theory
• Compare Q&A threads on data-driven development with those from more traditional software engineering
• Summarize your findings in a thesis and presenting them to an audience
• (Optional) co-writing a research paper

You need:

• Strong communication skills in english
• Good knowledge of data processing
• General knowledge of data-driven development

Communication is a key challenge when collaborating on large, complex software systems.In this thesis you will explore how phyiscal objects can help developers communicatethe architecture and design of their software to other developers and non-experts.

Your work consists in:

• Brainstorm visualization ideas
• Design and prototype physical artifacts that represent software design
• Evaluate these designs regarding their benefits for communication and comprehension
• Writing a thesis and presenting your results to an audience
• (optional) Co-writing a research paper

You need:

• Strong communication skills in german and/or english
• A good understanding of software architecture, design, and engineering
• Basic knowledge of rapid prototyping, e.g. CAD, 3D printing, etc.
• Good knowledge of user testing methods
