Filed: 2003-03-31
Abstract: <P>PROBLEM TO BE SOLVED: To improve the usability by a user by enabling the user to realize the content of character information or bar code information on a printed matter as one object.  <P>SOLUTION: When the character information or bar code information printed on the printed matter is optically read by an information reader 110, the start, in-operation, and completion of information reading are reported to the user. When the information reader is used as a pointing device, and touched to a predetermined position on the display screen of an information processing control device 120, the information processing control device performs a command processing corresponding to the display position on the display screen by use of the information read by the information reader. For example, when the information processing control device is a car navigation device, and a display position of "destination setting" (command execution-corresponding display position 150) is pointed, the information processing control device performs a route setting by use of an address read from a predetermined printed matter by the information reader.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
