Function extension device, function extension method, computer-readable recording medium, and integrated circuit

An object recognition unit recognizes, from real-space video data, a body included in the video data. A function setting unit retains function information in which is prescribed a function configured from a pair of operation and processing that can be set for each type of body. In addition, the function setting unit sets, to each body recognized by the object recognition unit, a function that can be set, based on the type of each body. A selection determination unit determines a selected body selected by a user as the body to be operated among the respective bodies recognized by the object recognition unit. An operation determination unit determines the operation that the user has performed on the selected body. A processing determination unit 1107 determines the processing for the operation that has been determined by the operation determination unit among the operations configuring the function set by the function setting unit.
