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

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

• 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
• Web Development Experience (optional)
• Interest in crypto currencies (optional)

Description

Tangible learning is a new way for learning, where the learners can be more engaged with their whole bodies. It has 7 benefits:

• Playfulness: Play is important nature of children's lives and promotes their "social, emotional, physical, and cognitive development". TUIs promote playful interactions with physical objects.
• Trial and error: TUIs foster exploration and experimentation in active play with trial and error. TUIs allow children to try different things and easily reverse their actions.
• Sensory engagement: TUIs engage multiple senses, which can aid the constructive learning process.
• Spatial learning: Tangible interaction improves spatial perception through physical embodied interaction, for instance rotating objects with one's hands. Spatial skills are important for everyday tasks, such as tool use and navigation, and are also linked to better performance in STEAM (Science, Technology, Engineering, Arts, and Mathematics) disciplines. TUIs can also improve spatial memory.
• Social connection: TUIs can be used for learning in groups and enable natural group interaction and discussion. Collaborative tangible learning environments could help children "get over their initial fears in the areas of mathematics and science and even begin to enjoy these subjects".
• Accessibility: TUIs can make learning accessible for children with impairments, for example, visual impairments or learning disabilities.
• Feeling of competence: By being able to directly manipulate objects with their hands, children can gain a sense of competence and autonomy while interacting with technology.

The aim of this project is to learn how to design a TUI for learning and see its effectiveness. For this purpose, we aim to understand the learning from a new perspective: fun, pleasure, playful and hands-on.

You will:

• Do a literature review
• Design a TUI prototype for learning
• Conduct user studies to get the feedback
• (Optional) co-writing a research paper

Requirements

• An interest in improving learning
• Good communication skills in English
• Have the experience to develop the technical prototype (if you don’t have, I can help you know some basic knowledge about the prototype development)

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

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

Procedure textures have been practiced for years, but procedure modelingis still slowly moving to be widely accepted, although there are successfulsoftware such as SideFX Houdini, Geometry Nodes in Blender that recently introduced in 2.92.

However, to proceed with procedure modeling, users have a high mental cost to be able to get started, such as having a general overview of the offered geometry nodes, dynamics, etc. Moreover, node-based modeling workflow visualizes traditional text-based programming setup but remains non-intuitive to tweak the node flow that produces the effects in the users' mind and almost impossible to enable manual fix all generative geometry details when we want to. It is interesting to optimize the not only learning cost but also user workflow here.

Description

OpenGL is a rasterization engine on the GPU side. However, rendering data on a GPU requires data copying from CPU memory to GPU memory (immediate mode), which is not a cheap operation in general.Instead of sending data, modern OpenGL manages vertex buffer objects (VBO) directly in the GPU memory but also requires additional concerns regarding memory management.

Instead of rendering everything on GPU, it is interesting to optimize and rasterize everything directly on the CPU in real time.

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

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?

Thanks to smartphones, we are always reachable and easily distractible. The first makes it hard for us to detach - from work ("just this one email, then I'm done for today"), pressure from friends and family ("why didn't you answer my message within 5 minutes?"), or the device itself ("what, half an hour passed whereas I just wanted to see what time it was"). On the other hand, once we are settled in, the latter makes it hard for us to focus - on a working task, a conversation, or our own imagination.Within this thesis, we want to develop and evaluate whether setting up a particular smartphone environment, i.e., customising the smartphone screen and functionality (wallpaper, color scheme, app layout, etc.) improves our focus and simultaneously encourages detachment.

Tasks:

• (Extensive) Literature review on smartphone solutions to support focus and detachment
• Enhancement of an existing Android launcher-based application with the findings from 1)
• Design and execution of a lab- and/or field study to evaluate the effect of the solution developed in 2)
• Analysis & discussion of the study results

Requirements: Very good programming skills with Android. A successful project can result in a submission to a renowned international conference/journal.

Machine Learning is a new paradigm for writing software where not one defined algorithm dictates the behaviour but instead data determines and changes how the software operates.Naturally, a different development paradigm means that we write different code.

GitHub as the platform for open source projects offers a diverse range of software repositories, traditional and using Machine Learning. In this thesis you will analyze publicly available repositories to determine how exactly Machine Learning code differs from more traditional code.

You will:

• Perform a literature review
• Collect and classify a sample of GitHub repositories that represent Machine Learning and traditional software development
• Compare what parts of the underlying programming language is used more or less for either
• 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 / extraction
• General knowledge of formal languages, parsing, etc.
