Abstract: In order to provide a composite object that can be produced at high quality and low cost using a 3D printer, a composite object includes: a first object obtained by assembling one or at least two assemblable toy blocks; and a second object constituted by one or at least two parts produced through 3D printing, and configured to be attached to the first object so as to cover at least a portion except for part of a surface thereof. Accordingly, it is possible to produce an object at high quality and low cost using a 3D printer.

Abstract: To solve a conventional problem that it is not possible to easily input information related to execution of a task, an interactive apparatus includes: a topic receiving unit that receives topic information, which is a topic for identifying a task, from a user terminal; an interactive unit that acquires question information indicating a question corresponding to the topic information and transmits the question information to the user terminal, and that receives answer information indicating an answer corresponding to the question information, from the user terminal; an information group acquiring unit that acquires an information group, which is two or more pieces of information satisfying a predetermined condition, from the one or more pieces of answer information received by the interactive unit; and an accumulating unit that accumulates the information group in an external information processing apparatus. Accordingly, it is possible to easily input information related to execution of a task.
