VR-based CAI Courseware System


Each design stage in which major work for the country I courseware design process F. Luk ITheflowchartoftedmkl ~ of ∞ uId providers identified I) Materials Analysis: CAI courseware for the analysis of raw materials, including the characteristics of the material structure. If the courseware materials are to learn computer application software, book, the software is a window-type graphical user interface,[link widoczny dla zalogowanych], is learning to use computers to chart-type data management skills and teaching materials; 2) Teaching Analysis: According to the conclusions and teaching materials of the object to determine the appropriate teaching methods. In this paper, individualized instruction, with the overall design of the structure of the algorithm. According to the distribution of knowledge points, throwing people from the deep, progressive design of the learning process, the basic process of learning algorithm shown in Figure 2, it is the material of each knowledge point for the study and design, is \4 |. Users to learn and practice taking into account the importance of integrating the courseware system using virtual reality technology and hyperlinks, set multiple operating platforms into one, so that operation and demonstration of combined exercises and operations, the operation process of demonstration and hands-on exercises algorithm in Figure 3 Fig. Learning algorithm flow loop 2 set ng. 2Thef10 ah roundworm 0f0flej Rights Figure 3 shows the process and operation of solid-Rose algorithm. 3Theflowchartoftbea_ithm0fd song Shí r \The number, lip treatment,[link widoczny dla zalogowanych], graphics, etc.; 4) interface design: human-computer interface for each module design. taking into account the characteristics of individual teaching. courseware particular attention to ease of man-machine interface and human-computer interaction mechanism design L5; 5) courseware maintenance: preliminary design of the courseware, not only to the overall commissioning and maintenance; but also in the application of multiple testing and debugging. 2.3 human-machine interface with other similar software, the main difference is the use of virtual reality system, designed and implemented a set of knowledge and learning, operational demonstrations and hands-on exercises as one of the learning environment. When the user enters the cAl courseware to integrated into a virtual learning environment - classroom, plus laboratory. students here can not only learn the necessary theoretical knowledge, well done in the classroom learning process; also in the virtual \process and friendly interface, simple operation. You can enable users in a system of learning environment, the study of theory and practice do not achieve out of touch, in a short period of time to master practical skills ~ the door. Figure 4 is the courseware interface of a virtual hands-on exercises . When you watch the operation and demonstration, after clicking the command button into the appropriate hands-on exercises interface can operate in time to practice. The interface can freely zoom in or out, part of the user interface can also be used to operate any practice . exercise time from 122 of Sichuan University (Engineering Science Edition) Volume 33 user control, you can repeat the exercise, you can also choose to practice [63. Figure 4 on exercises interface ng.4Thei ~ terfaee0fthee ∞ 0fet ~ ratltm3 Summary Throughout the world education development of computer-aided education is the inevitable trend of education reform copy. the introduction of virtual reality system for computer-aided instruction has added new vitality. There is no doubt that virtual reality technology in the field of education has a very attractive prospect,[link widoczny dla zalogowanych], although it practical applications, there are still many difficult technical issues to be resolved.
