Investigating the Impact of Customized Avatars and the Proteus Effect during Physical Exercise in Virtual Reality

Virtual reality (VR) allows to embody avatars. Coined the Proteus effect, an avatar's visual appearance can influence users' behavior and perception. Recent work suggests that athletic avatars decrease perceptual and physiological responses during VR exercise. However, such effects can fail to occur when users do not…

Improving Electromyographic Muscle Response Times through Visual and Tactile Prior Stimulation in Virtual Reality

Electromyography (EMG) enables hands-free interactions by detecting muscle activity at different human body locations. Previous studies have demonstrated that input performance based on isometric contractions is muscle-dependent and can benefit from synchronous biofeedback. However, it remains unknown whether stimulat…

The Effects of Avatar and Environment on Thermal Perception and Skin Temperature in Virtual Reality

Humans' thermal regulation and subjective perception of temperature is highly plastic and depends on the visual appearance of the surrounding environment. Previous work shows that an environment’s color temperature affects the experienced temperature. As virtual reality (VR) enables visual immersion, recent work sugge…

The Effects of Body Location and Biosignal Feedback Modality on Performance and Workload using Electromyography in Virtual Reality

Using biosignals through electromyography (EMG) and rendering them as feedback for hands-free interaction finally migrates to engaging virtual reality (VR) experiences for health and fitness-related applications. Previous work proposes various body locations as input sources and different output modalities for creatin…

Physiological and Perceptual Responses to Athletic Avatars while Cycling in Virtual Reality

Avatars in virtual reality (VR) enable embodied experiences and induce the Proteus effect - a shift in behavior and attitude to mimic one's digital representation. Previous work found that avatars associated with physical strength can decrease users' perceived exertion when performing physical tasks. However, it is un…

Reading in VR: The Effect of Text Presentation Type and Location

Reading is a fundamental activity to obtain information both in the real and the digital world. Virtual reality (VR) allows novel approaches for users to view, read, and interact with a text. However, for efficient reading, it is necessary to understand how a text should be displayed in VR without impairing the VR exp…

DIS '203rd AuthorPrivacy by Design & User Control +2

Implementation and In Situ Assessment of Contextual Privacy Policies

Online services collect an increasing amount of data about their users. Privacy policies are currently the only common way to inform users about the kinds of data collected, stored and processed by online services. Previous work showed that users do not read and understand privacy policies, due to their length, diff…
