To extract feature points based on bio-information of a user while being shaped, and to perform shaping by using virtual shaping data when extracting the feature points.SOLUTION: A bio-information analysis part 74 extracts feature points by acquiring bio-information from a virtual ceramic art control device 16 and analyzing the bio-information, and stores time line information on a period of extracting the feature points (synchronization information). When completing ceramic art work, the bio-information analysis part selects the time line information (synchronization information) stored in a time line information part 78. A feature point (a feature point B) where a peak value of the bio-information is the largest, for example, is automatically selected. Any of feature points A to C may be manually selected. When synchronization information is selected by a selection part 80, three-dimensional information of a period matched with the selected synchronization information (time line information) is captured from the virtual ceramic art control device 16, and transmitted to a three-dimensional shaping control device 44.SELECTED DRAWING: Figure 5
