Investigating Behavioral Realism of Single-Point IK Animated Avatars of Others in AR and VR
ElHassan Makled;Christoph Gerhardt;Tobias Schwandt;Florian Weidner;Wolfgang Broll
Publication Year: 2024,Page(s):1 - 8
Behavioral realism is a key element in social virtual and augmented reality (VR/AR). Different techniques, from full-body to single-point IK, are used to animate virtual humans, providing varying levels of behavioral realism. While the animation method of the user’s own avatar is important, e.g., considering embodiment, the animation of others is equally important to display a convincing immersive...Show More
Geometry-Based Optimization of Light Probe Placement in Virtual Environments
Maurice Teuber;Tobias Schwandt;Christian Kunert;Wolfgang Broll
Publication Year: 2024,Page(s):9 - 16
In order to achieve realistic lighting in augmented reality (AR), virtual reality (VR), and other virtual environments with stringent real-time requirements, environmental lighting is captured and stored in light probes that are strategically positioned throughout these environments. This study investigates the optimal positioning of light probes based on the environment to achieve realistic virtu...Show More
Embodiment in Virtual Environments - Analyzing the Effects of Latency and Avatar Representation
Publication Year: 2024,Page(s):17 - 24
The way a user is represented in virtual reality is a key element for applications ranging from entertainment to immersive communication and remote collaboration. Having realistic and expressive avatars leads to a stronger sense of embodiment and presence. However, they also lead to increased system latency, which can cause several negative effects, including cybersickness and a reduced sense of e...Show More
Mid-air images are CG visuals that float in real space and can be observed without using devices. Owing to the unique display of mid-air images, a virtual reality (VR) simulation system is essential for designing and evaluating interactions with these images. However, to date, no such simulations have been developed. We hypothesized that simulating characteristics, such as view area and occlusion ...Show More
Synthesis of Enthusiastic Collective Audience NPCs in VR Live Concerts
Publication Year: 2024,Page(s):33 - 40
Virtual reality (VR) live concerts have recently attracted much attention because of their various possibilities for future music entertainment in cyberworlds. However, it has been reported that current VR live experiences do not reach the levels of enthusiasm observed at actual live concerts, and achieving a sense of enthusiasm in VR live concerts is a challenge to offer enough engagement. Accord...Show More
One-to-many line matching across keyframes using minimum weight edge cover problem
Publication Year: 2024,Page(s):41 - 48
Inbetweening, interpolating between two keyframes, is an essential step in traditional handdrawn animation production. Many interpolation methods used to assist in animation production require correspondences between lines in two consecutive keyframes. This paper proposes a method for finding line correspondences that can apply to two keyframes, even those with occlusions. Our method determines on...Show More
The use of social VR content to communicate with others in a virtual space has been increasing. It is suggested that the frequency of physical contact is higher in communication on VR than in the real world, which improves the user’s liking for the other party. In this study, we aimed to improve the quality of communication by adding auditory stimuli to physical contact between avatars in a virtua...Show More
Visualization for Serve Form of Volleyball to Support the Improvement of Serve Technique
Publication Year: 2024,Page(s):57 - 63
The serve is the first attack and the key to the flow of the match in volleyball. This paper presents a visualization technique for the process of practice for a well-controlled serve. In this study, we ask players to hit the serve toward a target and measure the distance from the drop point and the coordinates of the joints. Then, we apply dimensionality reduction to the acquired coordinates and ...Show More
Procedural Generative Design for Spatial Layout Planning Using Hexagonal Cellular Automata
Publication Year: 2024,Page(s):64 - 71
Spatial layout planning in architecture is a complex, highly constrained problem with multiple objectives and wide range of possible solutions. Due to its iterative and time-consuming nature, it is desirable to automate and optimize the spatial layout design process. Here we present a procedural model with hexagonal cellular automata to automatically generate various spatial layouts from basic use...Show More
Rendering Delay Optimization for VR Streaming in IIoT with MIMO-NOMA-assisted Edge Computing
Xuan Wang;Zhigeng Pan;Mithun Mukherjee;Jielin Jiang;Xi Wu;Zhibin Liu
Publication Year: 2024,Page(s):72 - 79
Multiple-input multiple-output non-orthogonal multiple access (MIMO-NOMA) cellular networks are expected to support large-scale connectivity. This paper proposes a scheme that uses MIMO-NOMA technology combined with edge computing to alleviate the challenge of high latency in traditional VR streaming systems to optimize the rendering delay of virtual reality (VR) streaming in the Industrial Intern...Show More
Avatar Deformity and Task Loads Required to Induce the Sense of Body Ownership
Publication Year: 2024,Page(s):80 - 87
One of the characteristics of VR is the use of virtual avatars, which allow users to control a deformed body that is different from that of humans. However, the use of deformed avatars can easily lead to a decrease in the user’s sense of body ownership, which is the feeling of recognizing the avatar as one s own body. In addition, the relation between the degree of avatar deformity and the task lo...Show More
Prompt Assisted Generative Modelling for Digital Recreation of the Lost Caesar Paintings by Titian
Ivan Rybnikov;Ivan Lysikov;Yan Antropov;Manuel Portela;Hassan Ugail;Maadh Zameer;Noah Ugail
Publication Year: 2024,Page(s):88 - 95
This paper presents a machine learning approach to digital recreation of the lost Caesar paintings by Titian using prompt assisted generative modelling. We leverage Stable Diffusion XL (SDXL), a state-of-the-art generative model integrated with ControlNet and custom Low-Rank Adaptation (LoRA) models, to produce high-fidelity images that closely mimic the artistic style and historically accurate im...Show More
Convolution Neural Network for Finite Element Analysis of 3D Pipe Stress Distribution
Vei Siang Chan;Farhan Mohamed;Najwa Ayuni Jamaludin;Mohd Yazid Idris;Lih Fong Wong;Mohd Syafiq Mohd Suri;Sarehati Umar;Andres Iglesias
Publication Year: 2024,Page(s):96 - 99
Pipeline analysis plays an essential role in ensuring the structural integrity and safe operation of these critical components. Finite Element Analysis is the commonly used method for assessing stress distribution in pipelines. However, it can be computationally expensive and time-consuming, necessitating alternative approaches. The use of machine learning offers a promising alternative by providi...Show More
Experimental Movement Creation by Choreographers Using Augmented Body with a VR Device
Publication Year: 2024,Page(s):100 - 103
In this study, we developed a system to create artistic dance movements by augmenting body movements with a VR device to support dance creation. For creating movements, we implemented several methods that assume interaction in a virtual space, based on the existing dance methods used in choreographic creation. The methods generate movements that differ from the user’s movements by changing the bod...Show More
Automated Annotation Assistance for Pidgin Sign Japanese in Sign Language Recognition
Gibran Benitez-Garcia;Nobuko Kato;Yuhki Shiraishi;Hiroki Takahashi
Publication Year: 2024,Page(s):104 - 107
Japanese Sign Language (JSL) and Manually Coded Japanese (MCJ) are the two main forms of sign language used in Japan. The former differs significantly from spoken Japanese, while the latter closely aligns with spoken syntax. Pidgin Sign Japanese (PSJ) is an intermediate form that heavily relies on nonmanual signals such as facial expressions and head movements for grammatical nuances. Current sign...Show More
Effect of Transition Process to an Avatar on the Sense of Embodiment
Publication Year: 2024,Page(s):108 - 111
The sense of embodiment is important when using a virtual avatar, and by gaining the strong sense of embodiment, the connection with the virtual avatar becomes stronger, and it feels more like the virtual avatar has become your own real body. Therefore, the aim of this study is to propose a method for transitioning to an avatar that uses only a simple virtual environment and is not dependent on a ...Show More
