In this paper, we developed on internet based assembly information display system for the blind. The system is consist of hardware and software. The hardware is consist of a voice synthesis device and a tactile display for character information, and the software is consist of internet web browser for the blind and braille program. The tactile-device system consists of a control unit, pin array, pin generator, serial port, and a power supply. The pin exerted by a electromagnetic method, solenoid. The internet web browser separates the character and image from internet web page, and character information in the web page is converted to braille and fed to sound system. Also the image in the web page can be printed developed tactile display. As the results of experiment, the blind could access the internet web site by using this system and understand various internet information.

This study focuses on visual aesthetic factors in the apparel web site design. 103 undergraduates participated in the evaluation of six internet web sites. The evaluation were recorded and analyzed by using the inspection method and a questionnaire. Findings of this study can be summarized as follows: First, the result of SPSS-factor analysis shows that there are 2 distinct factors; 'classical aesthetics' and 'expressive aesthetics'. 'classical aesthetics' and 'expressive aesthetics' can be described by visual aesthetic design. This conceptual confusion relating to 'visual aesthetic design' can be clarified by these findings. Second, as a result of multiple regression analyses, 'classical aesthetics' and 'expressive aesthetics' have a positive influence on 'interactivity' and 'web site evaluation'. This research clarifies the concepts of 'engagement' of Rosen & Purinton as the 'interactivity' between users and web sites. Finally, this study suggests that 'good design' for internet web sites depends on understanding how to attain the appropriate balance between 'classical aesthetics' and 'expressive aesthetics', based on the target customer.

Since the World-Wide Web (WWW) has become a major channel for information delivery, information overload also has become a serious problem to the Internet users. Therefore, effective information searching is critical to the success of Internet services. We present an integrated search engine for searching relevant web pages on the WWW in a certain Internet domain. It supports a local search on the web sites. The spider obtains all of the web pages from the web sites through web links. It operates autonomously without any human supervision. We developed state transition diagram to control navigation and analyze link structure of each web site. We have implemented an integrated local search engine and it shows that a higher satisfaction is obtained. From the user evaluation, we also find that higher precision is obtained.

The aim of this research was performance of Web-based real time DGPS using MS visual basic 6.0 Active X control. This system supported the navigation of rover by transmitting the DGPS correction information of base station via internet and monitored the moving of rover by displaying the corrected results received from rover as well as permitting Web users monitoring for rover. The Web-based DGPS server and the client system using MS visual basic 6.0 Active X control for DGPS displayed on Web-browser with the pre analysis was constructed and the system loading test via Web-browser was performed after debugging this system through the static GPS test and publishing it on Web. Also, the wireless internet DGPS test on Web by changing the distance between a base station and a rover was carried out. As the result of the test, the real time DGPS could be performed by transmitting the correction message which calculated from the server system to the client system continually. The rover could be managed by displaying the location information which received from the client system. Other users also could monitor the rover by connecting with this system via internet in real time.

This paper is concerned with designing and implementing the Internet shopping mall by using virtual reality-driven avatar and web decision support system. Traditionally, the Internet shopping mall has been designed based on the combination of several hyperlinks, images, and tents. However, this sort of approach results in a lower performance because possible customers cannot make more accurate shopping decisions. To overcome this kind of pitfalls facing the current Internet shopping malls, we propose using a combination of virtual reality and web DSS. The main virtues of our proposed approach to designing the Internet shopping mall are as follows: First, the virtual reality technique is emerging as one of alternatives guaranteeing a sense of reality for customers' part and facilitating the complex process of shopping decision makings. Especially, the avatar, which is an artificially designed man working on the Internet, can make easy and absorbing the Internet shopping-related decision making processes. Second, the web DSS approach can provide an effective decision support mechanism for customers. Especially, we design a set of intelligent agents for the proposed web DSS. Experimental results with an illustrative example showed that our proposed approach can yield a new Internet shopping mall paradigm with which customers can benefit from a high level of decision support functions.

Recently, the development of internet remote control system has been studied lively along with fast growth of internet. In this paper, we proposed the internet-based remote control and monitoring system using java platform. The apache web server that is now used worldwide was constructed for monitoring and controlling of an machine in administrator's web browser. We solved the limitation on security which is the biggest problem of internet control system due to strong security setting in web server. As a result of experiment which is used in the proposed remote internet control system, several time-delay occurred in internet. However, correct control result could be achieved without an error. And this system monitored informations of a RPM, temperature and the other condition in almost real time.

The development of the Internet has influenced consumers' information search process and purchase behaviors. The environmental changes and consumers' lifestyle changes have stimulated them to use the Internet shopping mall. However, people used to shop the low-involvement product rather than high-involvement product such as clothing product at the internet shopping mall due to the subjects' perceived risks or product characteristics. The purpose of this study is to examine the differences of consumers' attitudes toward the two types of apparel internet shopping mall. With compared to the existing shopping mall, this study generated Web3D internet shopping mall by designing Abata, representing the user's body figure. The changes of respondents' attitudes toward the internet shopping mall and purchase intentions would provide the possibility and future direction of the Web3D internet shopping. Recommendations and future research were also discussed.

This study examined the effects of web-based learning experiences, learning style, and Internet self-efficacy that influence beginning child care teachers belief about web-based learning. The participants were 215 beginning child care teachers who work in child care centers. Data were analyzed by means of frequency analysis, correlation, and multiple regression for SPSS windows. The results were as follows: First, significant statistical differences were detected in web-based learning experiences and beliefs about web-based learning. Online teacher learning community use and frequency were significant gaps in beliefs about web-based learning. Second, there were statistical differences in learning styles and beliefs about web-based learning. And teachers with assimilator learning style showed high difficulty beliefs about web-based learning. Third, teachers' belief about web-based learning was significantly related to Internet self-efficacy. It means that teachers that have high Internet self-efficacy show high belief about web-based learning. Forth, among the teachers' personal variables, a higher level of online teacher learning community use and Internet self-efficacy predicted higher beliefs about web-based learning. Thus, this study suggested the importance of web-based learning experiences and Internet self-efficacy to beliefs about web-based learning. And it implicated ways to improve positive beliefs about web-based learning of beginning child care teachers.
