    Design of Body Transformation Experience
    (The Eurographics Association, 2023) Murakami, Taichi; Kitazaki, Michiteru; Abey Campbell; Claudia Krogmeier; Gareth Young
    Humans can feel an illusory body ownership towards bodies that are different from the real one. It has been well studied how the virtual embodiment can be realized and what can be embodied. However, it is not clear how we feel when our body changes from one body to another. We aimed to provide different experiences of body transformation by varying the transition patterns of avatars. We created five types of avatar transitions. In Flicker process, the body appearance changes instantly from one avatar to another, but with a blank screen in the middle. In Cut process, the body appearance changes instantly without blank. In Smooth process, the avatar's body appearance transforms gradually and smoothly according to a smoothstep function. In Linear process, the avatar's body appearance transforms gradually according to a linear function. InWave process, the avatar's body appearance transforms like a wave or back and forth according to a mixture of linear function and sinusoidal function. We expect that participants will be the most aware of body transformation in the Wave transition followed by Linear and Smooth transitions. The Flicker and Cut transitions are natural and less noticed by participants.

    Improvement of VR Science Teaching Materials That Visualize Invisible Elements and Evaluation as a Self-study use
    (The Eurographics Association, 2023) Fujiwara, Miraku; Terata, Yuki; Saruta, Kazuki; Chen, Guoyue; Abey Campbell; Claudia Krogmeier; Gareth Young
    Teaching materials using virtual reality (VR) technology are expected to further improve learners' understanding. However, it is assumed that the instructor's engineering knowledge may be insufficient to introduce these materials in the classroom, and that it will take time to educate the instructors. Therefore, we improved VR science teaching materials that visualize electric currents and magnetic fields for self-study at home, and reviewed their self-study use. Experiments were conducted with university students, and we found that our modifications improved usability and VR sickness.

    Mitigation of Fear Triggers for Image Viewing in Virtual Reality
    (The Eurographics Association, 2023) Hetterich, Amelie; Mammen, Sebastian von; Pohl, Daniel; Abey Campbell; Claudia Krogmeier; Gareth Young
    Modern VR image viewers combine immersive photos with audio, special effects and haptics to provide a highly immersive experience. However, users with specific phobias may encounter discomfort while browsing through random images, specifically, considering the high presence in VR. We explore strategies to reduce fear triggers and implement tailored mitigation measures in our image viewing app, specifically for 3D and spherical images. We address automating fear reduction in different VR formats, audio, and special effects to improve the accessibility and experience for VR image viewer users with specific phobias.
