This paper delves into the application of computer technology in the metaverse exhibition modules of Country Partner (CP) and Operation Partner (OP). It begins by noting the proactive response of Chinese educational institutions to the educational and research trends of the metaverse, highlighting the critical role of VRI AR, 5G networks, and the Internet of Things in constructing metaverse experiences. The paper thoroughly analyzes aspects such as design modeling of metaverse scenarios, aesthetic visual effects of scenes, digital twin design, and augmented reality technology, emphasizing the importance of interdisciplinary collaboration. In the CP aspect, it focuses on the application of metaverse spatial scenario design and human-computer interaction technologies, including the use of tools such as 3DMAX, Sketchup, and Unity. Regarding the OP aspect, it explores the application of computer technology by various positions in metaverse exhibitions, underscoring the potential applications of metaverse technology in fields like tourism management, exhibition specialties, and e-commerce. The paper concludes with suggestions for optimizing the application and innovative education of computer technology in Chinese universities, promoting the integration and development of new engineering and new liberal arts disciplines in the direction of the metaverse. © 2023 IEEE.

VR system generally includes three aspects: one is the intervener, that is, people. VR development must be based on human data and perception psychology. The second is virtual environment, which involves hardware equipment, software system, and content production. The third is the human-computer interface, which is the data way to connect people and virtual environment. This paper takes the 30th anniversary virtual exhibition hall of Yunmen College of Guangdong Buddhist Academy as a case, and uses 3D modeling technology and 360 panoramic virtual reality technology to build a synthetic digital exhibition hall. Virtual exhibition halls break the limitations of physical exhibition halls in terms of time and space, greatly expand the extension space and communication efficiency of exhibition information, and meet the functional expectations of the public for activity communication. © 2023 IEEE.

Molecular communications (MC) broadly defines information exchange using (bio-)chemical signals over multiple scales. The research in this area addresses various fields where MC plays an important role. Notable examples include 1) the modeling of living systems, which aims to gain new insights into biological systems;2) their interface with the outer world, aiming to develop techniques to control biological systems;and 3) synthetic MC, focusing on the design, analysis, and implementation of human-made MC systems at different scales.

digital human modeling for design and engineering conference and exhibition, dhm 2009

The use of digital human models (dhm) to perform geometric evaluations of hand clearances and reach zones has become common practice at Ford Motor Company. Moreover, dhms have also been used for performing strength evaluations to ensure ergonomically acceptable jobs. A process called Hose Connections Acceptability Ratings (HCAR) was developed to establish insertion force targets in the early phases of product design. Once targets are set, design and release engineers provide design intent data to achieve sign off from manufacturing engineering. The process is complete when the hose efforts are confirmed at physical part validation build events. Copyright © 2009;SAE International.

作者： Reed, Matthew P. University of Michigan United States

The human Motion Simulation Framework (Framework) is a hierarchical set of algorithms for predicting and analyzing task-oriented human motion. The Framework was developed to improve the performance of commercial human modeling software by increasing the accuracy of predicted motions and the speed of generating simulations. This paper presents the addition of stair ascending and descending to the Transition Stepping and Timing (Transit) model, a component of the Framework that predicts gait and acyclic stepping.

digital human modeling allows for the evaluation of equipment designs before physically building and testing prototypes. This paper presents an example of how digital human modeling was used to perform biomechanical studies on four new designs for future infantry headwear systems. Range of Motion (ROM) and cervical spine forces and moments were compared using static and dynamic simulations in a virtual environment. Results confirmed that headwear system prototypes with optimal overall mass and Centre of Mass (CM) location, as determined by previous human subject trials, exerted the least amount of biomechanical loading. Facial protection was favorable when considering forces and moments in the cervical spine, however when considering ROM, the rigid prototype mandible guards used in this evaluation are not recommended. The shape of a more accommodating mandible guard was developed, and the option to remove facial protection for some tasks was recommended. Copyright © 2009 SAE International.

Geometric estimation of FoV for vision modeling in dhm

Geometric estimation of FoV for vision modeling in DHM

digital human modeling for design and engineering conference and exhibition, dhm 2009

作者： Vinayak Sen, Dibakar Indian Institute of Science India

This paper presents a geometric method for estimating the filed-of-view (FoV) for monocular and binocular vision using a 3D scanned human face. The traditional vision-cone approach offers simplicity but may lead to spurious inferences during ergonomic evaluations involving peripheral vision. FoV is asymmetric due to unrestricted zygomatic vision and restrictions on nasal side. Thus its accurate modeling is important for effective simulation of visual performance. Given a tessellated face model and the location of the pupil, the present work computes the FoV edges on the face with respect to the pupil. The algorithm is divided in two steps, visible triangle computation and silhouette edge detection for FoV estimation. A qualitative comparison of samples with the standard perimetry data and right circular cones used in dhm shows that the FoV is very similar to the physiological visual-field maps and the cones used in dhm are conservative. The proposed approach has been extended to gaze dependant field-of-view computation which is difficult to obtain experimentally due to involuntary eye movements in subjects. The gaze-dependant FoV is found to be significantly different from normal monocular and binocular FoV. Thus the present computational FoV paradigm has the potential of active vision integration in performance evaluations using dhm's. Copyright © 2009 SAE International.

This paper presents the usage of the digital human Models (dhm) PCMAN and RAMSIS to determine parameters for a supported ingress and egress on a mock-up. Sports cars with lower seating positions show occurring difficulties among older drivers during ingress/egress. To equip sports cars with higher seats or narrow door sills seems limited due to design aspects. Therefore the idea of an ingress/egress support system arose. To build a mock-up, it needs specific dimensions already in the CAD design phase. Here dhm-systems are utilized. As no similar systems are known, no ballpark figures for trajectories of the seat or movement ranges can be derived from literature. Therefore pre-tests were done with a simple manually moved seat. Test persons showed high acceptance and discomfort reduction. In order to design a proper testing environment for repeatable and reliable results, a variable seat with electric motors is built into a mock-up with a package of a sports car. Previous tests of ingress/egress filmed from three perspectives on the same mock-up were digitized with PCMAN and imported to RAMSIS in CATIA V5. The manikin movements and CAD model of the movable seat are attached, while avoiding penetrations of body parts with any car geometry e.g. roof edge. Herewith it is possible to rapidly determine the range of movement for the seat in the mock-up. Moreover these requirements help to reduce costs and development time. The result of the study shows an application for dhm systems to specify the design of test environments. Copyright © 2009 SAE International.
