Before conduct data collecting, enumerators take a course and conduct simulation in the classroom. However, learning in the classroom often doesn't make the enumerators understand perfectly. To solve this problem, we can use 3D virtual game based training as a solution. During the training, enumerators will use 3D virtual learning environment to get more experience, engagement, and expertise. For...
Nowadays Learning Games are widely utilized in various domains to ease learning and capture the focus of learner using playful spring. Although many researchers show that using Learning Games increase motivation and interest. However Learning Games users still suffer from the high cost and difficulties of developing and designing an attractive learning game without being a designer or an informatics...
Virtual training is a relatively novel field in which human beings learn to perform certain tasks by repeatedly executing them in a virtual reality environment. To make such training environments more effective, the agent paradigm has proven to be a useful tool. By conceptualising a training system as a 'virtual tutor', the system may be able to support the trainee in a similar manner as human instructors...
Launched from the establishment of 3D tongue model in this thesis, the tongue rehabilitation training method of hearing-impaired child combined by 3D modeling technology and sensor technology is applied and the method can reveal the tongue motor process of average person when pronouncing, guide the hearing-impaired child to do tongue pronunciation training, overcome the problem of non-visibility of...
With the rapid development of the virtual reality technology, shortcomings of the conventional real equipments maintenance training can be remedied by adopting virtual maintenance training technology. This paper reviews the significance and development status of virtual maintenance based on virtual reality technology, including the basic functions and module design of equipments virtual maintenance...
Based on the problems appeared in some infantry fighting vehicle's actual training, this paper combines the advantages of virtual maintenance, proceeds from aspect of system engineering, takes demand of actual training into account, uses Solidworks, 3ds max and EON synthetically, chooses the form of desktop, set up a virtual maintenance training system of the equipment.
One of the great benefits VR systems offer is their ability to simulate a number of virtual humans when their presence is needed in the context of some learning or training experience. Being that the real humans may not be available to play different roles and support virtual sessions, the ability of a system to generate highly believable representations of autonomous virtual humans — virtual intelligent...
There are increasingly number of analog/mixed-signal circuits in microprocessors and SOCs. A significant portion of mixed-signal circuits are high-speed I/O links, including serial buses such as PCIE and parallel buses such as DDR. Post-silicon validation of I/O links is hard and time-consuming, and can be critical for making a product release qualification decision. In this paper, we try to summarize...
Virtual simulation technology is applied to complex substation construction, the process is the dynamic simulation of the substation construction process. Finally, combining sound and text to explain the simulation process, it provides the information about the substation construction for builders. More important, it can be used to train the new employees for the substation construction. It can also...
Starting from the CDIO engineering education model philosophy, on the basis of the analyzing of the problems of the traditional teaching of satellite communications course, the teaching reform research and practice of satellite communications course on CDIO Model was discussed. Practice shows that the pattern helps the students arouse the enthusiasm to study and train students in engineering practice...
With the rapid development of computer technology, Virtual Reality (VR) technology becomes more and more widely used in fields related to maintenance work. In this article, the composition and technical characteristics of VR technology is introduced, the development history and research background of VR technology is reviewed, and application status of VR system is analyzed. The application of using...
At the first time declare the application of virtual reality technology use in sports according to event-group characters (according to the classification of the dominant factor of competitive ability). Classify the training systems designed by scientific institutions in China and other countries, conclude the characters of virtual reality applied to different event-groups: technique oriented difficulty...
Two dimensional shape models have been successfully applied to solve many problems in computer vision such as object tracking, recognition and segmentation. Typically, 2D shape models (e.g. Point Distribution Models, Active Shape Models) are learned from a discrete set of image landmarks once the rigid transformations are removed applying Procrustes Analysis (PA). However, the standard PA process...
Virtual reality, with support of high interactivity, can present a virtual environment that resembles the real world. Its application in training opens new opportunities for effectively training workers with low cost and fewer hazards, and has been used in business training widely. An appropriate instructional design model that guides the development of a VR supported training environment is imperative...
This paper presents a cardiac motion modeling method that separates motion from anatomical patient specific cardiac features by using bilinear models on segmented heart volumes. This factoring in a quasi-independent anatomy-motion transform significantly reduces the dimensionality of the data to analyze: instead of having to check all the points on the volumetric mesh, we analyze a reduced number...
Since the medical training samples are very limited, it is difficult to construct a statistical shape model with good generalization using few samples. In this paper, we propose a novel statistical shape modeling method using 2D PCA. The 3D shape is represented as a matrix by spherical parameterization. The experiments showed that our proposed method can reconstruct statistical shape model with good...
The perception and awareness of chemical, biological, radiological and nuclear ("CBRN") emergencies is rising. These hazards are not directly detectable by human senses and thus no inborn reactions exist. As a consequence, special tools to detect these dangers have to be utilized. Since these dangers tend to affect large areas, it is necessary to establish standardized, coherent ??Best Practices??,...
At present, the vast majority of the research on promotion effects at home and abroad mainly focuses on single promotion means study based on statistical methods. This paper establishes an integrated model regarding the effects of the cost invested by telecommunication operators in each promotion means on sales increase and discusses the distribution of promotion cost among various means by combining...
The maintenance process model is a basic component for the virtual maintainability analysis and maintenance training. An extended Petri net was proposed in the modeling of equipment's maintenance task process. The expressions of the maintenance tasks relations and maintenance resources are discussed; the maintenance resource object token is proposed to enhance the description capability of the model,...
