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.

Problem Statement

In the 21st Century, mental health disorders like stress, anxiety and depression have become a part of our daily lives. Current digital systems are largely blind to users’ stress states. Systems that adapt to users' states show great potential for creating novel user experiences. However, most approaches for sensing stress, involve obtrusive technologies, such as physiological sensors attached to users' bodies and not yet adapted to VR/AR. In this thesis, we aim to explore unobtrusive sensors for detecting stress, while considering VR/AR setups.

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.

There is a growing acceptance that machine learning-based intelligent systems need to be capable of explaining their behavior in human-understandable terms to prevent unintended consequences in sensitive contexts of society (e.g., credit scoring, recruiting, predictive policing, or criminal justice). The field of explainable artificial intelligence (XAI) develops models, methods, and interfaces that are interpretable to human users by providing some notion of explanation. Often, the quality of these methods is assessed based on subjective user perception ratings instead of objective gains in user understanding.

This evaluation practice may be misleading because of the illusion of explanatory depth (IOED). Psychology research has demonstrated in many contexts that humans have a robust bias of overconfidence regarding their understanding of how complex things work. After being asked to explain their understanding, people significantly reduce their estimation of their own knowledge.

We are looking for a thesis or practical research student to jointly design and conduct experiments to examine if the IOED applies when users are exposed to explanations from XAI systems.

• Review of prior research at the intersection between IOED and intelligent systems
• Design and conduct a suitable experiment that examines the existence of IOED in XAI
• Analyze and evaluate the findings using qualitative and quantitative research methods

• Background in human-computer interaction, psychology, or computer science
• Independent working habits and creative problem-solving skills
• Experience in web development and/or machine learning is a plus

Description

Cryptocurrencies have gained attention in the public eye increasingly. A 2018 study found that two thirds of European consumers are aware of cryptocurrencies. Yet, less than 10% of people surveyed actually bought cryptocurrency. One possible explanation is the high (technical) understanding required to engage with the technology.

The goal of this thesis is to investigate how novel onboarding strategies affect user experience for users who previously did not engage with cryptocurrency technology. How do existing Coin Management Systems (Wallets) approach the onboarding of new users? At which points do new users struggle during the initial setup? How can effective onboarding facilitate a better user experience?

Tasks

• Review of related literature
• Analyze and categorize existing wallets
• Design and conduct user study (with cryptocurrency non-users)
• Development and implementation of an effective onboarding system
• Evaluation of the implemented system

Requirements

• Independent thinking and creative problem solving
• Interest in designing and conducting user studies
• Knowledge in the area of human computer interaction
• Web Development Experience
• Interest in cryptocurrencies

Description

Over the past years, cryptocurrencies (e.g. Bitcoin, Ethereum) and their underlying technology, Blockchain, have experienced increased interest and a steadily growing user base. Contrary to transactions in centralized systems, it is hard to foresee the time a transaction needs to complete.

The goal of this thesis is to investigate how the status of cryptocurrency transactions can be “best” displayed to users. How existing cryptocurrency and blockchain solutions display the status of transactions to users? Which information is shown and which temporal metaphors are used? How do (end-) users perceive different methods? And how do different transaction times influence, how users perceive them?

Tasks

• Review of related literature (wait times, loading screens, display of async transaction stati)
• Creation of “Transaction Models” for comparable systems (banking, messaging, cryptocurrencies)
• Analysis how existing systems (e.g. wallets) display transactions status
• Development and prototyping of improved methods to display the transaction status of cryptocurrencies
• Design of a user study and evaluation of the developed methods

Requirements

• Independent thinking and creative problem solving
• Interest in designing and conducting user studies
• Knowledge in the area of human computer interaction

Description

Das Konzept der unbewussten Wahrnehmung bekam vermutlich durch das Coca-Cola Experiment, welches durch Schleichwerbung in Kinofilmen angeblich einen höheren Verkauf erzielt hat, erstmalig öffentliches Interesse. Die unbewusste Wahrnehmung beschreibt eigentlich die Verarbeitung von visuellen Reizen, die für eine bewusste Verarbeitung zu schwach sind (z.B. zu kurz dargestellt). Damit können interessante Effekte wie Emotionen und Intuitionen hervorgerufen werden, die der Proband sich selbst nicht erklären kann. In dieser Abschlussarbeit wollen versuchen durch unbewusste Reize das Verhalten der Versuchspersonen zu beeinflussen im Webseiten.

The concept of subliminal perception first came to light to the general public through what is known as the The Coca-Cola experiment, through which an advertising of cola and popcorn was displayed “subliminally” in a cinema and an increased consumption was noted. Subliminal priming refers to the use of a stimulus, whether visual or auditory, to transmit information to the automatic mind subconsciously. The primes can be subtle visual changes or cues of very short duration that are not consciously processed. In this BA/MA thesis we are interest in exploring subliminal visual priming for influencing users in website navigation and guiding them towards their intended goal.

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 conducting 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 conducting user studies
• Good programming skills
• Prior experience with VR technologies (Unity, SteamVR) is considered an asset

Description

In this project, the student will extend a previous project called GravitySpot (link; video; talk). GravitySpot is a system that guides users to specific spots in front of large interactive displays using cues that implicitly guide users. For example, in case of a display with which users can interact via mid-air gestures, a perfect position to guide users to could be 2-3 meters away from the display, but in case of interaction via eye gaze, this position could be 30-60cm away from the eye tracking device. GravitySpot guides users by showing them on-screen cues that implicitly guide people to the correct position.

In this project, we aim to implement GravitySpot 2.0, which guides multiple users in front of large displays to one or more optimal interaction positions. We attempted to implement GravitySpot 2.0 before. We started by following the same approach adopted in the first version i.e. showing on-screen cues to guide each user in a different way. However, we quickly realized that a prerequisite is to first make sure the user knows which on-screen cue they should follow. This led us to question how users identify themselves on public displays. In our investigation of this problem, we published this work (link; video).

Tasks

• Build on the two previous projects to implement and evaluate GravitySpot 2.0. Taking some points into consideration e.g. the kinds of situations GravitySpot 2.0 should cover.
• Review of previous work on interaction with public displays is necessary.
• Conducting user studies and evaluating the data
• Handling of depth imaging data from a motion sensor (e.g. Kinect)

Requirements

• Good programming skills
• Interest in conducting user studies

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.

Description

Virtual reality provides novel opportunities for users to experience immersive simulations of reality. At the same time, we still have a limited understanding of how such simulations can go beyond just imitating the real world. This project focuses on musical interfaces, in particular, playing piano.

The objective of this work is to come up and implement novel concepts for playing piano in virtual reality. One possible example is a concept for tracking finger movements with a motion tracking system to better understand performance and to build user interfaces with the goal of enhancing this performance.

This project is available for 1 or 2 bachelor/master students.

Tasks

• Review of related literature
• Designing new concepts for piano playing in VR
• Implementing VR visualization and tracking / sensing
• User study
• Analysis and report of the findings

• experience with hardware programming helpful
• interest in working with Motion Tracking
• interest in piano playing (or musical instruments in general) a plus

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

Description

Virtual Reality is increasingly being used as a research tool. It is particularly useful in situations, where users should not be put at risk, for example, when testing a novel automotive user interface; or where running a study in the real world is a lot of effort.

At the same time, affective user interfaces, that respond to or evoke certain emotions are becoming increasingly popular. However, it is unclear yet how well emotion elicitation works for different tasks commonly done in virtual reality.

The objective of this thesis is to obtain a thorough understanding the lasting effects of emotions in humans during performing tasks in VR. We look into different tasks in VR, different emotion elicitation methods and how long the emotions last. The thesis requires the design and implementation of a user study to understand how task performance is affected due to emotions in VR. In addition, this work also explores how negative mood elicitation affects task performance.

Tasks

• Comprehensive survey of related work
• Design and development of a prototype
• Evaluation of the prototype and comparison to previous work

Requirements

• Independent scientific work and creative problem solving
• Interest in performing user studies and experiments
• Interest in VR
• Experience with C# 3D authoring tools (e.g.,Unity) is preferred

Description

Virtual Reality is increasingly being used as a research tool. It is particularly useful in situations, where users should not be put at risk, for example, when testing a novel automotive user interface.

At the same time affective user interfaces, i.e. interfaces that are either emotion-aware or aim to influence users' emotions are become increasingly popular. Similarly to VR, this line of research is particularly relevant in the context of automotive user interfaces, because it has the potential to lead to safer driving.

As of today it remains unclear, how well state-of-the-art emotion elicitation methods work in VR, which is at the focus of this thesis. The thesis specifically focuses on one elicitation technique, called autobiographic reflection. The idea is that participants recall a situation that evoked a particular emotion. This techniques is promising in automotive research, since it does not rely on any visual or auditory cues.

The objective of this thesis is to obtain an understanding of Autobiographical Recall technique in detail and how well it works in Virtual Reality. We aim to explore the various recall approaches work, including but not limited to talking to an avatar vs. no avatar, telling the story aloud vs. writing it down, recalling the situation while a research is present / while no researcher is present. Ultimately, design considerations for specific use cases should be derived.

Tasks

• Comprehensive survey of related work
• Design and development of a prototype
• Evaluation of the prototype and comparison to previous work

Requirements

• Independent scientific work and creative problem solving
• Interest in performing user studies and experiments
• Interest in VR
• Willingness to learn Unity

Generative music systems are becoming more and more relevant nowadays. In the near future Artificial Intelligences will become evenly equal partners in music making scenarios. Therefore we have to find ways to interact with systems that are able to make their own decisions and have their own creative mind. Established communication with human musicians are eye-contact, gestures, verbal expressions.How can we communicate with digital musicians, how can they communicate with humans?

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.
• Experience in programming and hardware-prototyping.
• Ambition to delve into hardware and software.

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?

Tasks:

• Concept Development.
• Design Experimentations.
• Prototyping.
• Evaluation in form of a User Study.

Requirements:

• Prototyping Experience.
• Interest in Design and UX Design.

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

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
