To assist correction of a result of character input or character input itself without changing a holding position of a microphone or a pen.
First, a face picked up image of an operator picked up by an imaging camera 138 is acquired (step S11), a movement pattern of the face is recognized from the face image (step S12), and the recognition pattern is compared and collated with a pattern in a database DB1 (step S13). When a coincident pattern is detected as a result of comparison collation (step S14), the command is read and comparison-collation is performed with a command in a database DB2 (step S15). It is decided if the command exists (step S16), when it is not detected, an error is displayed (step S17), and when it is detected, an edit operation command corresponding to it is read and outputted (step S18).
