SOLUTION: An instruction input device 101 outputs instructed display information, a cooking information storage device 102 stores cooking information and outputs it, and a user intention computing device 103 estimates intention of a user from the output by the instruction input device 101 and the cooking data lately given to the user. A long-term storage device 108 sequentially stores the cooking data lately given to the user and the output by the instruction input device for analyzing course of the intention of the user. A user interest computing device 104 estimates interest of the user from the output by the long-term storage device and the output by the user intention computing device. A data evaluation device 105 evaluates the degree of interest of the user in all the cooking information from the output by the user interest computing device and the output by the cooking information storage device, a data processing device 106 generates image information to be given to the user from the output by the data evaluation device, and an image information output device 107 presents the image information to the user.
