Obesity is a serious disease that can affect both physical and psychological well-being. Due to weight stigmatization, many affected individuals suffer from body image disturbances whereby they perceive their in distorted way, evaluate it negatively, or neglect it. Beyond established interventions such as mirror exposure, recent advancements aim complement treatments by the embodiment of visually altered virtual bodies reality (VR). We present high-fidelity prototype an advanced VR system...
Realistic and lifelike 3D-reconstruction of virtual humans has various exciting important use cases. Our others’ appearances have notable effects on ourselves our interaction partners in environments, e.g., acceptance, preference, trust, believability, behavior (the Proteus effect), more. Today, multiple approaches for the exist. They significantly vary terms degree achievable realism, technical complexities, finally, overall reconstruction costs involved. This article compares two with very...
This paper introduces an automated 3D-reconstruction method for generating high-quality virtual humans from monocular smartphone cameras. The input of our approach are two video clips, one capturing the whole body and other providing detailed close-ups head face. Optical flow analysis sharpness estimation select individual frames, which dense point clouds computed using multi-view reconstruction. Automatically detected landmarks guide fitting a human template to these clouds, thereby...
This article investigates the effects of different XR displays on perception and plausibility personalized virtual humans. We compared immersive reality (VR), video see-through augmented (VST AR), optical AR (OST AR). The alter egos were generated by state-of-the-art photogrammetry methods. 42 participants repeatedly exposed to animated versions their 3D-reconstructed in each three display conditions. reconstructed additionally modified body weight for repetition. show that types lead...
Virtual reality applications employing avatar embodiment typically use virtual mirrors to allow users perceive their digital selves not only from a first-person but also holistic third-person perspective. However, due distance-related biases such as the distance compression effect or reduced relative rendering resolution, self-observation (SOD) between user and mirror might influence how embodied avatar. Our article systematically investigates effects of short (1 m), middle (2.5 far (4 m)...
Abstract Human shape spaces have been extensively studied, as they are a core element of human and pose inference tasks. Classic methods for creating model register surface template mesh to database 3D scans use dimensionality reduction techniques, such Principal Component Analysis, learn compact representation. While these models enable global modifications by correlating anthropometric measurements with the learned subspace, only provide limited localized control. We instead volumetric...
3D morphable models are widely used to describe the variation of human body shapes. However, these typically focus on surface body, since acquisition volumetric interior would require prohibitive medical imaging. In this paper we present a novel approach for creating template and fitting scan person in just few seconds. The model is composed three layers bones, muscles, skin, which enclose muscle fat tissue between them. Our includes data-driven method estimating amount mass from scan,...
Realistic full-body avatars play a key role in representing users virtual environments, where they have been shown to considerably improve body ownership and presence. Driven by the growing demand for realistic humans, extensive research on scanning-based avatar reconstruction has conducted recent years. Most methods, however, require complex hardware, such as expensive camera rigs and/or controlled capture setups, thereby restricting generation specialized labs. We propose WILDAVATARS, an...
The illusion of virtual body ownership (VBO) plays a critical role in reality (VR). VR applications provide broad design space which includes contextual aspects the surroundings as well user-driven deliberate choices their appearance potentially influencing VBO and other well-known effects VR. We propose protocol for an experiment to investigate influence deliberateness context-match on presence. In first study, we found significant interactions with environment. Based our results derive...
