Coma stimulation program (CSP) is a treatment in which a health care professional or a patient's family member systematically applies stimulation to patients' five senses, for the purpose of increasing patient responsiveness. In this study, we developed a CSP system in which the sensory stimulus was generated by a virtual reality (VR) technique to improve the therapeutic process. The article also...
This paper presents an approach for parametric design of human models, which can be used in virtual try-on system, games or other virtual reality (VR) environment. Consumers are assisted in automatically generating a virtual model through modifying the standard one by controlling the measurement parameters. Our approach consists of four major parts. First, 3D scanner data is preprocessed and provides...
Viewing scene system is an important component for driving simulator. Its authenticity can give user sense of reality and immersion. Aiming at overcoming the shortcomings of the previous virtual traffic environment model, a new method is presented in this paper, i.e. using software 3dsMAX to construct 3D entity, then transform to 0.3ds format and import to Eon Studio for simulation. The finished virtual...
The driving intelligence of the virtual intelligent vehicle in the driving simulation system is crucial to the system's sense of reality and the reliability of the experiment. This paper focuses on the features and functionality of the virtual intelligent vehicle in driving simulation system. Intelligent vehicle should first distinguish the roadway network in order to drive correctly along a certain...
It goes without saying that the means of designing product is changing following the appearance of the times of information, and the digital design with deep modern features has become the main tool of industrial product design. In the paper, severe of digital technologies which have been paid attention to by domestic and oversea scholars are introduced particularly, including reverse engineering...
Virtual assembly (VA), one of key technologies in advanced manufacturing field, is a promising application of virtual reality in design and manufacturing field. It has drawn much attention from industries and research institutes. In this paper, through the analysis to the theory of virtual assembly, with the aid of Pro/E to establish models and transform models into the form of VMRL form, we design...
Due to the increasing demand of customer in variation and personalization of products, static, textual and 2D display of products are no longer satisfactory for presenting products on the Internet, especially for 3D digital products such as domestic electronics, industrial equipments and medical instruments. This paper aimed at the specialties of present network based on virtual display of 3D digital...
The paper researched visual realistic simulation focused on virtual assembly, and proposed a algorithm and theory of normal rectification, according to the feature of virtual assembly: after models are simplified, making use of Phong shading to build lighting-model through modifying and equilibrating normal. It can still make models more real in the status which has little detail and less facets,...
Swept surface model of a drum cutter is established and discretized into uniformly distributed voxel model by ray casting approach. Solid model of the cutter is stored in the form of three mutually perpendicular rays array along X, Y, Z axis, with each ray being originated from the cutter swept surface and offset from its neighboring one at a distance of voxel size, resulting in a compressed dexel...
The idea of primordium in the packaging design is a kind of sincere creation going back to life. It is presented in the information society that can certainly enable the modern virtual packaging design to have the longtime vitality and the continuous nature
Exhibition industry is an emerging service industry. It plays an very important role in the aspects of economic restructuring, new markets exploitation, consumption advance, enhancement of cooperation and exchanges, expanding of products export, and promotion of socio-economic development. But with the limit of exhibition venues size, weather, traffic, time, cost and other factors, the development...
Using distributed display technique, scene can be divided into several parts from different angle of view. When they project to different screens, the multi channel display effects can be achieved, and it is possible to simulate specified interactive virtual reality environment with high immersion. According to the specialty of virtual driving simulator, adopt the construction technique and components...
