ABSTRACT:
An information input method and interface, which can easily be operated without direct awareness of hardware, are provided. Image recognition is performed with an image recognition unit on image information obtained from imaging a target pattern on an object surface and an access indication pattern created by a user. The input patterns are created with an image pickup unit. The target pattern is associated with corresponding information stored in a storage unit. An access indication input which specifies a subset of the information is generated by performing image recognition on the access indication pattern. A control operation corresponding to the access indication input is performed in response to the access indication input by a control unit.
