BA/MA: Usable Security in VR/AR

Usable security for virtual and augmented reality systems (VR/AR) is an area that is relatively underexplored. This thesis aims to investigate the feasibility of authentication mechanisms for VR/AR, while considering the usability and security aspects, specifically potential attacks.

Tasks

• Get familiar with VR/AR hardware and software
• Get familiar with authentication techniques
• Find and study related literature
• Develop\reuse software tracking the body motion and model it in VR
• Design a user study
• Conduct a user study
• Do a statistical evaluation
• Write all down in a thesis

Preferred (but not necessary) qualification

• Knowledge in the area of human computer interaction
• Independent thinking and creative problem solving
• Experience in programming with Unity a plus

BA/MA: Unobtrusive Stress Detection in Virtual Reality

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.

• Knowledge in the area of human computer interaction
• Independent thinking and creative problem solving
• Experience in programming with Unity a plus

MA:  Eliciting Emotions in VR

Emotion is a psyscho-physiological process triggered by conscious/unconscious perception of objects or situations. Emotions play an important role in human communication. Emotion assessment is often carried out through analysis of users' emotional expressions and/or physiological signals and eliciting emotion can be purposeful for various research work. The advent of Virtual Reality devices provides an opportunity to explore part of the research in VR which have been conducted in the lab until now.

The objective of this thesis is to obtain a thorough understanding of how suitable Virtual Reality is for conducting psychological research. The student is required to review previous work that investigates the use of VR as a research tool continuing to investigate one use case in more detail. The thesis requires the design and implementation of a user study to compare if VR is as effective as the Real World to measure emotional experience on the valence-arousal scale.

• Comprehensive survey of related work
• Review of relevant research questions in the application area
• Running a comparative user study (both in Real and Virtual World)
• Analysis, reflection and discussion of the outcomes

• Independent scientific work and creative problem solving
• Interest in performing user studies and experiments
• Interest in VR
• Nice to have experience with 3D modelling and programming with Unity

MA:  Understanding How Visual Appearance in VR Affects Human Behaviour

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.

• Comprehensive survey of related work
• Review of relevant research questions in the application area
• Running a comparative user study (both in Real and Virtual World)
• Analysis, reflection and discussion of the outcomes

• Independent scientific work and creative problem solving
• Interest in performing user studies and experiments
• Interest in VR
• Nice to have: Experience with 3D modelling and programming with Unity

MA: Understanding Interpersonal Interaction in Virtual Reality

The objective of this thesis is to understand how interpersonal interaction in Virtual Reality differs compared to similar contexts in the real world. This knowledge is valuable in order to understand whether real world studies can be complemented with investigations in the real world.

The successful application is required to study the effects of proxemics and F-formations in VR, delving into one specific application scenario. Possible areas include but are not limited to public displays, automotive user interfaces, e-learning, etc.

Tasks

• Comprehensive survey of related work
• Review of relevant research questions in the application area
• Running a comparative user study (both in Real and Virtual World)
• Analysis, reflection and discussion of the outcomes

• Independent scientific work and creative problem solving
• Interest in performing user studies and experiments
• Interest in VR
• Nice to have: Experience with 3D modelling and programming with Unity
