Integrating new input devices and their associated interaction techniques into interactive applications has always been challenging and time-consuming, due to the learning curve and technical complexity involved. Modeling devices, interactions and applications helps reducing the accidental complexity. Visual modeling languages can hide an important part of the technical aspects involved in the development...
As the mobile robots and various robot contests became very popular in the last few years, we developed the concept of a novel event for the students of our master module “Mechatronics and Robotics” - a virtual robot contest” The main idea was to allow them to participate in a robot com petition and to design control strategies for various robot tasks without having a real robot. Instead, they can...
Over last years, Indoor Positioning and Navigation Systems (IPNS) has been subject of intense study and research ought to it has become a blind spot with regard to Positioning and Navigation Software. None of proposed indoor solutions has been as successful as outdoor systems like Global Position System (GPS). Our proposal presents the design and implementation on mobile device(the most common), of...
There are much unstructured data in all kinds of application systems. It is very important to manage these unstructured data and transform them into structured data. XML language is very suitable for data storage and data exchange. Data transformation utility was developed using Microsoft Visual Studio 2005. The textual data in Microsoft word table files can be transformed into text file, the data...
To address the serious problems in e-commerce based on traditional 2D image-word, the author introduced Web3D, Flex and SSH technologies into e-commerce, presented “3D Virtual Reality & Flex” Web architecture for e-commerce, researched mechanisms of their architectures, and implemented their integration and communication & interaction: Flex and Struts2 via XML, Flex and Spring & Hibernate...
In view of the insufficiency of current remote simulation resource sharing and visualization technology, based on B/S mode and distributed interaction simulation's characteristics, the new design and method which aim at the remote simulation are provided, making the best of the J2EE architecture. Particularly RMI and the JNDI technology have solved the problems of the remote simulation resources'...
Analyzing the characteristics of existing three-dimensional visualization software technology, a method of modeling three dimensional spatial data and publishing on Web is discussed in details. A Web-3D technology model is presented based on Java 3D and GWT-ext, which provide technical supports for spatial information management and remote engineering control.
Discuss of design of the e-business interactive platform used on virtual reality technology was done, and the difficulties in the process were investigated, which was followed by corresponding solutions. It results to following conclusion: a) The problem of motion picture flicker can be commendably solved by using double buffer memory of technology with Java. b) In allusion to exceptional situation...
The paper first outlined the Java3D technology in three-dimensional model of interactive design applications. Proposed the use of Java3D virtual three-dimensional model for the description of the client to read through the remote server customers to upload three-dimensional graphics data, user interaction with the virtual three-dimensional interactive modeling program, using the procedure of drawing...
This paper discusses a long-distance virtual teaching platform based on VRML-JAVA language which is realistic and interactive information construction and scene guided by situational learning theories in views of insufficiency in modern long-distance network teaching. Based on characteristics of VRML and JAVA language, we introduce the structure and function of this platform to realize the platform...
The system, which provides edit and management tools of thematic map, can reduce the collection cost of urban environment data and increase the degree and scope of data share. This article shows composing of Web-based urban environment management system (Web-UEMS), supporting technologies, system architecture, database, system module, solutions of developing Web-UEMS, and appliances of Web-UEMS based...
Multi-agent systems have been proposed to support the distributed environment of collaborative design for many years. This research proposed two different communication architectures based on two major distributed object models, Java RMI and CORBA/Java. These two architectures could be applied in any agent systems supporting Java technology. Experiments were designed and conducted to measure the performance...
This paper discusses the work undertaken by the China Water Museum to develop X3D-based Water Museum Virtual Reality Experience System (WMVRES) to educate the public on water resources and the history of water. This system is to deal with difficulties in applying 3D information system in virtual reality experience, which is written in Extensible-3D(X3D) and Java. Administrators of this system manage...
The traditional development of 3D Web-GIS Applications is mainly based on the COM component of GIS software, which provides 3D visualization library and client-sever software architectures. This development method is still not sufficient in supporting the remote management of 3D pipelines because the client and the server involved in the process may require a frequent, two-way communication as well...
This paper analyses problem-based learning (PBL) process and involving various data types. We bring forward a "centralism transmission-distribution computation" hybrid computation model in terms of the data time-property and characteristics. The model adopts multiple layers soft architecture for ensuring the system scalability and suitability, obtaining lesser quantity of data transmission...
Since experiment is one collaborative activity and usually needs people collaborate together, itpsilas very important to study how to realize the collaboration among users in remote experiment. In this paper, the architecture of an Agent-aided cooperative model and its cooperation mechanism are proposed. Based on the architecture, one Agent-aided collaborative virtual experiment system is built. It...
With the continuing growth of the Internet, more and more people are taking advantage of distance learning courses. However, most of long-distance education systems can not be effectively implemented chemical experimental teaching. Learners can not make a practice in network environment, which is not conducive to the consolidation of learning and practice skills training. In addition, some existing...
This paper proposes a framework for J2EE-based cooperative design and investigates several associated technological issues. The proposed framework consists of XML-based system architecture for data transferring, the client with a ACIS/Hoops 3D core, and a J2EE-based application server. We also illustrate our solutions on how to develop the user interface of the client, how to construct a cooperative...
A server-decentralized Internet model based on Jabber for robot tele-operation with P2P stream media transfer supplement based on JXTA is proposed. The system is composed of four components: operators, robots, transfer servers and data-keeper. The robot-controlling data/robot state data are packed with XML stanzas and delivered to the resolved robot/operator through XML streams. The locale audio/video...
