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.

Description:

Shopping and consumption is a major cause of CO2 emissions. Thus many people state that they would like to buy more sustainable, but face difficulties actually doing it [2].

Self-Reflection increases the awareness on and impact of one's activities. E.g. keeping a diary on food wasting makes people think on their behavior and can lead to aiming for change [1].

The aim of your thesis would be to create a system that supports people to shop more sustainable. By reflecting on the bought goods, the buyer should be triggered to think about their decision. Additional information (e.g. carbon footprinting) could be used help the user judge their products.

Your work consists in:

• Literature review on self-reflection, HCI supporting sustainability
• Conceptualization and design of a system for self-reflection on consumption behavior
• Implementation of a prototype of your system on an appropriate platform
• Writing a thesis and presenting your results to an audience

You need:

• Strong interest in the above topics
• Motivation to work yourself into literature and compile the current state of the art
• Some experience on human-centered design processes for software systems
• Skills to implement your system on an appropriate platform, e.g. one of Android, iOS, the web, a mobile cross-platform framework ...

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.

Discrete Locomotion (e.g. teleportation techniques) is due to the fact of being less susceptible to cybersickness a widely applied paradigm for locomotion in Virtual Reality (VR). This topic is centered around the development of a spherical representation of a World in Miniature (WIM) which serves as a navigation tool for first-person locomotion in virtual environments (VEs) such as VR games or other immersive experiences. Subsequently a developed spherical mapping needs to be aligned with a fully tangible spherical controller that allows for the exploration of the VE by rotation or possibly the integration of finger based gestures. Finally, a study has to be conducted to test the developed concept against established discrete techniques and/or another approaches for a tangible WIM based on a flat surface.

Tasks:

• Development of a spherical mapping for a cartesian 3D space.
• Exploration and implementation of concepts for tangible interaction for locomotion by teleportation.
• Execution and evaluation of a user study for comparative results.

Requirements and prerequisits:

• Strong knowledge of a 3D engine (e.g. Unity or UE4) and a good understanding of algebraic basics of 3D programming.
• Interest in tangible VR-interaction and locomotion techniques (e.g. in first person games).
• Ability to work with and eventually extend existing hardware prototypes.

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

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 conducting 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 conducting user studies
• Good programming skills

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

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

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

In Human-Computer Interaction research, evaluation is used to understand the strengths and weaknesses of novel user interface concepts and their implementations. The objective of this thesis is to understand the research questions that can be answered using Virtual Reality. The advent of Virtual Reality provides us with an opportunity to transfer parts of the research until now being conducted in the field to the lab. With this goal in mind, we aim to understand how human behaviour is affected by various factors in Virtual Reality. Our objective is to gain an insight on how the visual appearance (for example: design of the room, certain appearance of objects, etc) of the fully immersive environment affect how humans behave in a certain context and how (visual) manipulations of the VR user's context influence behavior.

The task of the successful application is to review previous work and subsequently investigate one application area in more detail. Possible areas are automotive interfaces, large public displays or appliances for smart homes. The work includes a detailed analysis of the strengths and weaknesses of the approach.

Tasks

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

You can choose between different 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

A growing body of research shows that personality traits can be automatically inferred from users' digital texts, e.g. conversations with chat bots or social media posts. Like other personal data, we think that users' personality data might be captured in the future without users' knowledge and out of their control. This raises, in our opinion, ethical and privacy concerns and might potentially lead to misuse. We assume that depending on the context, users might not be comfortable with being profiled and its potential consequences. Together with you, we want to find out, which coping strategies users would employ to avoid being profiled by intelligent algorithms, i.e. how they try to ``trick'' the algorithm.

Tasks

The thesis comprises of the following 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
