BA/MA: Shoulder Surfing behavior in online VR platform

With recent restrictions on physical interactions, users are increasingly using online platforms for communication. This led to an increase in online virtual reality (VR) platforms such as Rec Room, VRChat among others. In this thesis, we would be exploring how the online VR platforms affect our behaviour (in the context of shoulder surfing) compared to in-lab VR situations. The objective of this thesis is to obtain a thorough understanding of shoulder surfing behaviour among users of online VR platforms. The student is required to review previous work in this topic and also review online VR platforms. The student is also required to conduct a user study using one online VR platform. 

Recommended Skills and Interests:

1. Interest in VR/AR technology
2. Knowledge in qualitative and/or quantitative research methods
3. Interest in conducting a thorough literature review
4. Interest in learning, e.g Unity

BA/MA: Lasting effects of Emotion Elicitation in VR?

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 of 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.

BA/MA: Effect of avatar appearance and embodiment on Emotions

Virtual Reality is increasingly being used as a research tool and among many other fields, this is beneficial to the affective studies (for example emotion elicitation methods). In this thesis we will explore how different avatar appearance and embodiment affect emotions. The thesis requires the design and implementation of a user study to understand appearance affects emotion. Implementation requires different avatar designs.

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.
