It researched the applying of augmented reality, based on it, Used digital scripting language, Three-dimensional modeling and interactive animation technology, designed the system. In the paper, the augmented reality technology applied to education for disabled children, it promoted the...
Vehicular Ad Hoc Network (VANET) is an emerging field of wireless networks that facilitates different applications such traffic information for participant vehicles and related authorities. However, deploying of such applications is mainly depending on the market penetration rate of this technology. In this paper, we propose a new 3-steps approach for estimation of traffic volume in a road segment...
The implementation of a virtual environment is challenging when the area to be covered is of large scale with existing objects such as historical buildings, castles, city neighbors, traditional villages etc. The desire for high fidelity is compromised by the computer machine limitations thus imposing a certain trade-off between fidelity and performance being thoroughly investigated in this work. In...
This study aims at investigating the advances in terms of the reconstruction capabilities offered by an ad-hoc imaging procedure capable of accounting for the actual radiation features of the Ground Penetrating Radar (GPR) antennas. The study is carried out by using a ‘synthetic setup’, which is implemented with a numerical tool able to simulate the characteristics of the antenna system as well as...
In the scenario of computational interfaces development, research efforts aim to offer new ways of interaction that are closer to the natural way in which humans interact with the real world. Amongst the diversity of interface modalities, the tabletop tangible interfaces make the link between physical and virtual objects, enabling to grasp and interact with their components in a physical manner, besides...
Commercial computer aided design (CAD) tools are single user, thus only allowing one user to contribute to a CAD model at a time. The NSF Center for e-Design, BYU site is developing multi-user plug-ins for commercial CAD systems to extend their functionality to allow multiple users to simultaneously contribute to a collaborative design model. One central issue in developing and working in a multi-user...
In the process of collaborative design, a large number of versions are produced. Storing and accessing versions is very frequent, so version storage in the process of collaborative design has become the core issue of version management. In recent years, how to reduce the storage space and improve the retrieval efficiency has become a research hotspot, however the research of version security is still...
Olkun defines spatial reasoning as “the mental manipulation of objects and their parts in 2D and 3D space.” In a previous study, the author found that physical model building increased student spatial reasoning by 12% on average, as compared to drawing the same topic as an axonometric drawing. To further this study, this paper will examine the effect of two different types of model building exercises...
Simulation training using virtual patients can provide many benefits for nursing and medcial students in learning patient interaction skills, especially since virtual patients can represent a wide range of patient scenarios and demographics that are not typically represented through roleplay or clinical rotations. However, creation of a single virtual patient scenario may take six months or more,...
This paper will discuss the development of a university course designed to provide the objectives, materials, and methods appropriate for teaching STEM in a middle school in Mississippi. The STEM course consists of ten thematic units. One of the units, Exploring CAD, discusses how to integrate creative arts in the STEM course using CAD and 3-D modeling. Lessons for each unit are designed using the...
Virtual Reality is an important aspect of the state-of-art technologies. The emerging trend to integrate the highest level of interactivity in the computer-oriented activities like web pages has introduced a new dimension in various aspects of computer-oriented services. Electronic commerce (e-commerce) is such a sector, which may be greatly facilitated with the touch of interactive virtual reality...
This paper presents the possibilities and usage of metrotomographic measurements using Metrotom device. The main motivation is to evaluate the precision of the scanning for complex objects. We also present a comparison of measuring strategies, which round up in the conducted experiment. In this experiment, we have paired a cloud of points of the measured element with its CAD model. With each one of...
As a kind of Chinese culture, Chinese Kung-fu has been very popular in movies and TV programs and attracted the interest of people all over the world. The paper address the problem to recover Chinese Kung-fu from video sequence for further use in computer games. Human motion capture for animation and VR has reached a level of capturing real motion data from people using various visual and non-visual...
In order to facilitate the laying of deep drainage pipes, we have improved to design one kind of catchment reinforced water seepage hoses, and then analyzed the structure, principle of the drainage and advantages of the hose. Furthermore, we have verified the feasibility and rationality of the catchment reinforced water seepage hoses by Indoor performance test and geotextile permeability test.
The next generation network is an effective measure to solve the current existing problems of the network. And the routing and exchange is the key to implement the next generation network. Thus, it is needed to study and sum up in-depth. First of all, this paper introduces characteristics of the next generation network. Then, it tells the requirement of routing and exchange. After that, it introduces...
This article through literature retrieval, questionnaire and other method to investigate and analyze, and analyze the advantages of the application of virtual experiment in secondary vocational school experiment class. This paper systematically describes the related design theory basis. On this basis, overall to design platform performance, experimental modules, development tools and development process...
Since the virtual reality technology has some special characteristics, such as immersion, interaction and imagination etc., which is very suitable to the simulation teaching. In this paper, we integrate VRML, ASP, 3D, JavaScript etc to design and build a virtual laboratory (VL). In VL, considering about the visual, auditory, tactile and other feelings, we adopt the monomer combination model mechanism...
We propose to illustrate a methodological approach aimed to establish a "Digital archive of the Italian Masters work in the second half of the 20th century". To this end, we consider the architectural project — from its graphic layout — as a cultural heritage. Being as part of the field of new representational forms investigation, this work aims at designing, analyzing and communicating...
Traditional human-computer interaction requires input devices such as mouse, keyboard, trackpad and joystick. They suffer from a too high conceptual distance between how users have to interact with a computer and how they would like to interact with the computer. Today, computer hardware (e.g., processor speed, multicore, computer memory, data bandwidth), technology (e.g., availability of a wide range...
