PROBLEM TO BE SOLVED: To enable a user oneself to smoothly select an article. SOLUTION: When the user 1 who selects the article from virtual stores 4A, 4B and 4C on the Internet selects a desired virtual store among the virtual stores displayed on a user's display device, data on a list of articles that the selected virtual store handles are sent from the virtual store and a system server 2 sends an URL as the address indicating a file place where three- dimensional data on the articles that the virtual store handles are saved. When the user selects an article, the storage destination of three-dimensional image data corresponding to the selected article is retrieved according to the saved URL and the three-dimensional image data are sent from the storage destination; and the selected article based upon the data is experimentally mounted on a basic three-dimensional image model displayed on the display device and whether the article can be selected is determined. |
