Abstract:
A block set assembled by a user and an information processing device communicate with each other. The information processing device thereby obtains information on the structure of the block set. In addition, an object of a crane truck corresponding to the block set is displayed on a display device. Correspondences between joints and wheels and correspondences between movements are set. Thereby, when the block set is moved, the movement of the block set is reflected in the object on display. When the object is moved, the movement of the object is reflected in the block set by transmitting a control signal from the information processing device.
