Since the interaction with immersive visualizations can be crucial to finding the desired information, this work seeks to explore the possibilities of improving this kind of interaction by providing tangible touch points in the form of drones. Not only is the tracking of the drones a vital aspect but also the finding of meaningful behavior that is applied to the drone after it has been touched and manipulated, is at the core of this work. After a prototype model has been found for interaction and drone response it will be tested and evaluated on various immersive visualizations by conducting a user study that is centered around the ease and amount of gaining of information.

Tasks:

• Literature research concerning tangible interaction with virtual reality visualizations especially focused on drone-interaction.
• Setting up and tracking a drone to act as a tangible point.
• Conducting of an evaluative user study integrating various visualizations.

Requirements:

• Basics in Unity 3D (C#) and 3D modeling.
• Interest in tangible VR-interaction.
• Plus: experience with three dimensional interaction concepts.

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.

In highly automated driving, people are able to not care about driving tasks anymore. Meanwhile, increasing numbers of car interior concept showed the trend of combining bigger interactive screens with the physical car interior to offer novel infotainment system inside vehicles. Such concepts will offer more opportunities for users to deal with non-driving-related tasks such as relaxation or working on their way. However, the car interior with these screens of fixed position and size are neither within the reachable distance in terms of ergonomics, nor beneficial towards group conversation or multiusers. To address such problem, the goal of this research is to explore novel concepts of the car interior as tangible user interface for people wearing VR headset during autonomous driving.

Requirement

• Skills and experience of Unity
• Interest in automotive and tangible user interface

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

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

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.

For more then 2500 years humans already practice the interaction with flying agents for hunting and caretaking tasks. Based on the metaphor of the falconer we want to implement a system which enables gaze control of drones utilizing a wearable eye-tracker. By taking the "looking at the watch"-pose, which is reminiscent of the "falconer luring its bird"-pose, the eye tracker gets implicitly positioned in front of the user's face. A combination of body posture and eye gaze allows for GUI-free interaction in the field and during physically demanding tasks. In this thesis a VR prototype should be implemented that is used to perform an user study evaluating the interaction metaphor.

Tasks:

• Design Concepts.
• VR Implementation.
• Evaluation in form of a User Study.

Requirements:

• VR/Unity Interest/Experience.
• Eye Tracking Interest.

The internet changed the way we learn new languages, independent temporal factors, location, and budget. To increase motivation and engagement, learning applications often conduct a user personalization. Adapting the content has proven to be important due to the individuality of learning goals. Still, current language learning applications don't apply real personalization but let the user pick the most suitable contents.

In this Einzelprojekt, we want to investigate an approach to find gaps in user's second language vocabulary knowledge by analyzing physiological signals during media usage (watching english films with subtitles). In a user study we want to assess those signals from a medial grade EEG and an eye tracker. The data will be analyzed and evaluated to find features, which could be predictors for language understanding problems. These features are indicators, which help a cognition-aware system to identify words or sentences the user does not understand

Tasks:

1. Brief literature review on the use of EEG and eye tracking data to assess problems in language learning / understanding
2. Formulation of a concept / list of features relevant for language learning
3. Development of a study setup for testing languages
4. Design and execution of a user study
5. Analysis & evaluation of the study results

Requirements

1. Interest in physiological sensing techniques
2. Good / very good programming skills in the programming language Python and optionally Matlab
3. Experience in planning and conducting user studies

If this project is successful, you will get the chance to contribute to an international publication.

Description

Personalization is one of the biggest trends at the moment since it allows systems to target their users personally. Currently, personalization in HCI is often based on past user behavior, preferences, and interaction context. Personality traits, a concept of Psychology, could provide a promising additional source of information for personalization, which goes beyond context- and device-specific behavior and preferences. For example, Netflix users could get recommendations based on their personality or health app could provide information and decision support strategies based on personality.

However, which mental model do users have regarding the concept of personality? Are there universal negative and positive personality traits? What do users expect of personality-aware personalization and adaptation based on personality? Do users accept personality-aware adaptation?

It's possible that several students work on Bachelor's or Master's theses answering one of the questions mentioned above each.

Tasks

• Literature research regarding personality traits and personalization
• Develop a concept to answer one of the research questions mentioned above
• Implement the concept
• Evaluate the concept with an empirical HCI method

Minimum requirements

• Interested in personalization and psychological topics
• Previous experience in conducting user studies
