Web-based Three-dimensional Simulation System For General Psychology Experiments And Implementation

Psychologic experiment is the most important way to promote advance in and research into psychology, and normal psychologic experiment plays vital role in psychologic education. There are many flaws in psychologic experiment by optical and electronic instrument and it is strong tendency that psychologic experiment is done with computer, namely done by psychsoftware. Be short of sense of truth in course of doing experiments by two-dimension images psychsoftware used in local computer and with the tendency of distance learning, it is very important and practical to develop three-dimension psychsoftware based on WEB.What I did is below in research into system of three-dimension psychsoftware based on WEB:1 Researching into deficiencies of current psychsoftware of normal psychology experiments and analyzing feature and requirement of normal psycholgy experiments, appoach for three-dimension psychsoftware realized with VRMLJSP and Servlet technologies based on WEB, is raised.2 Software's requirement analysis and definition, system analysis, system design and DB design are done with UDP, a new software development tool with UML; software skeleton are designed with MVC design pattern.3 Building experiments scene with VRML is put an emphasis on , and interacting between circumstance and experiments scene , namely transmission mechanism of events and data between VRML and Java is also researched into. Interacting between circumstance and experiments scene is implemented with JSAI and EAI interfaces.4 Researching into communication mechanism between Applet and Servlet, system function of uploading data from client to server is implemented.5 Researching into technology of JavaBean, DBConnectPool, data security and inserting a batch of data into DB, DB connection, operation and displaying result and closing connection is implemented with JavaBean.6 System function of controlling experiment material's displaying time isimplemented with mutilthread technology.7 In accordance to system and skeleton design, psychsoftware based on WEB is implemented with VRML, Applet, and JSP and Servlet technology.
