Research On Mobile Terminal-oriented Adaptive Human Computer Interaction System

With the development of wireless technologies and the population of wireless communication equipments, people are no longer satisfied with the fixed information access methods. They start to use wireless equipments(such as PDA, the intelligence cellular phone etc) to finish their mobile E-commerce trade, such as the wireless E-mail service, the cellular phone bank service, the stock bargain and so on. At the same time, mobile E-commerce also changes the business mode of the enterprise gradually; we can use the service of the enterprise at any time and any place. How to develop mobile application efficiently, how to resolve the problem of the network access speed and the heterogeneity of accessed devices, All these put forward with the new request and techniques challenge to the research of each layer of the computer science. So the thorough analysis and research of mobile terminals and different network are carried on this thesis. The limitations of interaction features and HCI design principle of mobile terminals are analyzed. A conclusion of the architecture of network and system realized method of mobile terminals is given.There are four main parts in this thesis: putting forward the topic research way of this thesis, studying the design of mobile terminal interface, analyzing the architecture of network content self-adaptive system and the realization of self-adaptive system. The main works have been listed as follows:(1) Analyzing the change of computing pattern, according to development of current network technique and communication technique, proposing the subject of research on HCI of terminal and mobile device-oriented adaptive system.(2) As the mobile device's limitation, such as portability, not fixed position, limit calculation ability, low bandwidth, the design principle of mobile interface by HCI technology is studied in this thesis. Input and output methods of mobile interface, realization technology of mobile interface are also described.(3) Introducing the development of content self-adaptive deliver technology, it solves the problems that different network equipments can't visit the same network contents. According to the deliver mechanism of content self-adaptive system, it can be classified into three types: Client-side adaptation, Server-side adaptation Proxy-based adaptation and Annotation-based adaptation.(4) Studying the structure of content adaptive system, analyzing the module of client network environment monitoring and the module of decision engine carefully. The problems solved in this system are enumerated in detail. At the same time, the mobile device adaptation system which based on web annotation is studied.(5) Describing the wireless application protocol, proposing a kind of solution based on Java, WML and XSLT for content adaptation of different terminals. Give the detailed introduction of the primal problem, and make simulative experiment to test its validity.(6) In the end, the thesis aggregates the research of contents, and makes an outlook of this thesis's research.
