The Virtual Reality System in Electronic Commerce Li Zhao College of Information Guizhou University of Finance and Economics Guiyang, 550005,China Ning Zhang College of Information Guizhou University of Finance and Economics Guiyang, 550005,China 3820530 Abstract-The virtual reality system in electronic commerce provides a real dummy Shopping environment. Compared to the two-dimension electronic commerce shopping environment, it offers more feel experience. In order to realize the easy-use, communication and direct-feel, the virtual reality system needs many objectives, such as landmark, avatar and district. Finally, it constructs an electronic commerce shopping center with considering the function of the electronic commerce shopping interface by software Virtool. Keywords: electronic commerce, virtual reality, landmark, avatar I. INTRODUCTION The electronic commerce interface enters into virtual reality area stepped from pure text, image, simple two-dimension technology with the support of browser to multi-media. The virtual reality means that the virtual environment is similar to the reality environment to the utmost. The key technology is correlated with electronics, informatics, mechanics and biology and so on. It has a close relationship with human cognizing activity. Virtual reality is the communication bridge between users and virtual environment. It is a three-dimension space for users moving the objectives of the operation system. Through the visual, audio and touch feel, the consciousness and experience will forme. Based on the cognizing, virtual reality system is the pipeline of cross dialogue process and communication control including two information flows: input information and output information. During the process of input and output, users entered into the perceiving pipeline composed by visual, audio and touch feel through the control pipeline composed by the attitude, language and gaze, thus forms cross communication. Virtual reality system transmits the information by three behavior model: (1)travel: shift the users viewpoint from one place to another; (2)selection: click the objects in the virtual environment;(3)manipulation: set the location and direction of the objects. Compared with the human-computer interface, virtual reality system contains more complex objects, behaviors, communication and interactive in the relative natural environment. The users will feel being there in visual and own the same objects for freedom action as in the real world. TABLE1 shows the difference between conventional interface and VR interface. TABLE I.

THE FACTORS IN REALIZING THE VR SYSTEM For the differences between the virtual environment and traditional environment, when users browse in the virtual environment, they need the navigational support. Therefore, VR environment must have study character besides easy browse, which is related to the objects size, direction and information shows. In order to realize an accurate space, it needs a serial of browser clues, such as landmark, edges, districts, nodes, path, to make the abstract pace turn to embodiment. A. Landmark With developing the space relationship, landmark can show the direction and location of the objects, and apply the conditional world experience to the virtual environment. Landmark is an important actor in browsing. As a reference point, landmark will tell what people should do at anytime by reducing the distortion through the construction and configuration of itself when people perceive. Landmark must obey the configuration rules in virtual environment. Rule 1 VR must have landmarks. When the users experience of the environment adapting is increasing, the judge precision of the path distance, comparative direction and landmark location will increase. Rule 2 Landmark must be attractive so as to help people remember where they are. Rule 3 It should use the idiographic objects to design the landmark. Three-dimension objects landmark let the browsing be easier than the two-dimension. It will enhance the users memory ability. Rule 4 No matter how wide the browsing view is, it must be clear to see the landmark. In another sentence, the users should see the landmark both in small scale view and big scale view. Rule 5 Landmark must be distinguished with other objects around it for differentiating. Rule 6 Landmark should be set at the main road. The combination of route and signpost can reduce the amount of 8332012 IEEE Symposium on Robotics and Applications(ISRA)978-1-4673-2207-2/12/$31.00 V 2012 IEEElandmark. Especially when the browsing is based on the route knowledge, landmark is an important assistant. The new user will greatly rely on the landmark and will study the route knowledge that how to transfer from one place to another place. With the experience increasing, the user can transform the route knowledge to survey knowledge. The VR system permits users to finish task with the easiest view. However, it exists distortion at the process of survey knowledge. The cognitive map which shows the space order and torsion through grid area can be adopted for enhance correction. Cognitive map realize the effect by obeying some rules. For example, in order to make sure area A at left of the area B, all the objects in area A must be at left of the all the objects in area B, by illustrating in figure1: Area A Area B Figure1. the Rule of Cognitive Map Users can judge distance and direction correctly by the grid area. But it must satisfy follow rules: Rule 7 Route and district shape grid area. Rule 8 The main axis of the landmark is accordance with the axis of the grid area. Rule 9 The main axis of the landmark is accordance with other main axis. B. Avatar Avatar is the image of the user in the virtual environment. With the substitution in, users can freely move at their own will. They can clearly know how to control avatar and what the relationship with the real world. Therefore, avatar is considered as that user in the VR environment moving view direction, controlling objects and taking action. In order to realize these effects, avatar must satisfy three rules: Rule 10 The visual embodiment of the user: More natural the image of avatar is, more feel of being there the user will have. Rule 11 Avatar must have kinds of means of interaction with the world. Rule 12 The users have means of sensing various attributes of the world through avatar. C. The Evaluation Standard of VR System VR system must have the characters of direct feeling, friendly interface, humanistic operation if it wanted to have the same effect with the real world. The evaluation standards are: Easy using: The operation is easy. All the operation methods of control components are easily cognized and understood. Study: Users can easily study the operation processes. Operation: Every control component can be operated in VR system. Complexity: The complexity degree of operation construction and process in the system. Communication: Users and system can have dialogue with each other. Intuition: Whether wide the view in VR is. Information: How much the amount of information in VR system. Suiting: Whether different users are habit to the environment change. III. THE REALIZATION OF ELECTRONIC COMMERCE VR SYSTEM A. The function of Electronic Commerce VR System The function of electronic commerce includes a natural shopping space, products and services for sales, the communication between consumers and firms. Therefore, the space division and function set in VR system can be that which are shown in the TABLE 2 TABLE II. THE DIVISION OF THE ELECTRONIC COMMERCE VR SYSTEM Division District Content ShowHall The entrance of the target marketplace constructionThe newest information Rolling texts Target Marketplace The abstract of the commodity The shopping atmosphere: music, temperature, colorThe links to the more information of the commodity text, picture, voice, video Information Area The detailed information of the commodityThe information unit, individuation The users operation to the commodityAvatar The links to other pagesHyper-linkConsultative Area The frequency questions and answersThe Avatar of the consultant Consumers prefer to natural shopping environment. The shopping center is the best choice for VR system design. B. The Realization of the VR System The computer operation system is higher than windows9X. The designer software is Virtool Web Player higher than edition 2.1. 1) The Entrance When consumer is near the shopping center, He/She can see an avatar, knowledge map and construction of the shopping center. The knowledge map is at left of the screen forever. Avatar stops or walks on the road. The sign of the shopping center and kinds of advertisements are hanging in the building. The effective map is like with figure 2. 8342012 IEEE Symposium on Robotics and Applications(ISRA) Figure2. Entrance 2) Knowledge map Knowledge map is composite with function option area and information show area. The function option area includes the two bars which are separately in the left and right of the knowledge map. The operation actions include: map, search, manual, contact, zoomIn, zoomOut, fullScreen and close. The information show area takes on the whole relationship of the VR shopping center to consumers in plane map. It can be seen in figure 3. Figure3. Knowledge map 3) Information Getting After consumers find the object commodities, they can select and click commodities links, then enter into the detailed information area to get more information, such as characters, prices, functions. The effective interfaces are similar with the figure 4 and figure 5. Figure 4. Commodity Show Figure 5. Detailed information IV. CONCLUSION Based on the discussion of the virtual reality system, this paper realizes part functions of a shopping center with considering the factors of the electronic commerce system. However, this paper just explores the compendium of VR shopping environment without considering a lot of detailed affairs especially in how to finish the whole shopping processes in a VR system. The future research can deeply consider all the cases.
