Description

Shoulder surfing refers to situations where a person observes another person's private interactions with technology (e.g., private messages on a smartphone, or personal identification numbers on ATMs). In this thesis, we will investigate how VR can be used as a platform to study shoulder surfing. In this context, we will explore the effect of audio feedback on behavior in VR, covering both the attacker and the victim.

The objective of this thesis is to obtain a thorough understanding of how audio feedback in Virtual Reality affects human behaviour in the context of shoulder surfing. The student is required to review previous work on shoulder surfing and particularly its prior applications in VR. The thesis requires the design and implementation of a user study in VR.

Tasks

• Comprehensive survey of related work
• Review of relevant research questions in the application area

Description

Biocybernetic adaptation is a form of physiological computing where real-time physiological data from the brain and the body can be used as an input to adapt the user interface. In this way, from the physiological data, we can infer the user’s state and design implicit interactions in VR to change the scene to support certain goals. This thesis aims the develop and evaluate an adaptive VR environment designed to maximize users' performance by exploiting changes in real-time electroencephalography (EEG) to adjust the level of visual complexity. The research consists of three main stages: (1) validation of the input EEG measures underpinning the loop; (2) implementation of a working VR prototype; and (3) an evaluation of the adaptive environment. Specifically, we aim to demonstrate the sensitivity of EEG power in the (frontal) theta and (parietal) alpha bands to adapt levels of visual complexity.

You will

• Perform a literature review
• Modify an existing VR environment
• Implement an online biocybernetic loop using EEG
• Collect and analyze EEG, EDA, and ECG data

Description

Research from cognitive science and computerized displays of simple stimuli has shown how perceptual load is a critical factor for modulating distraction. Perceptual load is the amount of information involved in processing task stimuli. According to Lavie (1995), our attentional resources are limited and mainly directed towards task-relevant goals, but we might be more prone to distractors if we have cognitive spare resources. Previous research showed that human faces have bigger distracting power than non-face objects. This project aims to assess the distracting potential distracting effect of human avatars in a social VR scenario. We aim to transfer of traditional paradigms that assess attention and distraction to immersive VR. Lastly, we adapt the target-distractor recognizability to evaluate if a physiologically-adaptive system that optimizes for perceptual load can support task performance. The research consists of three main stages: (1) validation of the psychophysiological inference underpinning the physiological loop (2) implementation of a working VR prototype, and (3) an evaluation of the adaptive environment.

Description

Physiological computing is a multidisciplinary research field in HCI wherein the interaction depends on measuring and responding to the user's physiological activity in real-time (Fairclough, 2009). Physiological computing allows for implicit interaction; by monitoring the physiological signals of the user, the computer can infer, e.g., if the task demands are either too challenging or easy, and either adapt the difficulty level or when users are getting distracted from the task, the system could give them a notification. Measuring the psychological state of the user creates intriguing possibilities for Social VR scenarios as we can either adapt the number of displayed avatars, their form or even their proxemic distance. This thesis aims the develop an adaptive Social VR environment designed to support users' performance when engaged in a cognitive task using a measure of physiological state (electrodermal activity: EDA) as input for adaptation. The research consists of three main stages: (1) validation of the psychophysiological inference underpinning the physiological loop (2) implementation of a working VR prototype, and (3) an evaluation of the adaptive environment.

Imagine Bob's office is connected via a (quantum-)encrypted connection to a server. How could Bob access this server from his home office if he does not have the necessary hardware at home? Well, he could get keys in his office and save them on his personal key-safe token. He could subsequently use the token at home and connect to the server.

The topic of offline distribution of cryptographic keys is interesting for researchers and practitioners alike, even outside the QKD context. Hence, exemplary open questions include: Which use cases for offline key distribution exist? How could the key-safe token look like (design, usability and security)? Is there a possibility to detect unauthorized access to the token?

With the increasing proliferation of augmented reality glasses (e.g. Hololens), we are getting closer to the vision of truly mobile interaction in a digitally augmented physical world. As a consequence, a major part of the interaction with such devices will happen on the go. This establishes a need for interaction and visualization techniques that support the user in highly mobile situations. In this thesis, we will prototype and evaluate such interaction and visualization techniques to better support users while interacting on the go.

Tasks:

• Development of interaction concepts
• Prototypical implementation
• Design and conduct a user study

Requirements:

• Good programming skills (C#, Unity is a plus)

Mixed reality describes a continuum between physical reality and complete digitality (i.e., virtual reality). Both, reality and digitality, offer inherent advantages and disadvantages depending on the use case. For example, a higher degree of digitality causes a loss of connection to the real world and, on the other hand, a higher degree of reality decreases the immersiveness of the experience.In this thesis, we will investigate how the positive and negative factors of reality and digitality affect different usage scenarios. Furthermore, we want to investigate how users can move on this continuum, i.e., how they can control the amount of digitality and reality.

Tasks:

• Development of interaction concepts
• Prototypical implementation
• Design and conduct a user study

Requirements:

• Good programming skills (C#, Unity is a plus)

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
