INFORMATION INPUT METHOD, INFORMATION INPUT SHEET, AND INFORMATION INPUT APPARATUS

摘要

An information input apparatus, an information input method, and an information input sheet which a user can easily operate without directly having to become aw are of hardware are provided. An information input sheet includes a display area having an input information area and an identification area in which an identification code of t he input information is provided. The identification code of the input information is pro vided in the display area as a target pattern having a rotation mode in which a code is d efined by a directional orientation of the target pattern. An image pickup unit generates im aging information from imaging the information input sheet. The imaging information in cludes imaging information of the identification area of the information input sheet. B ased on this imaging information of the identification area, the rotation mode of the ta rget pattern, as recognized by an image recognition unit, is determined. The rotation mode spe cifies the identification code of the information input sheet. Information on the infor mation input sheet is authenticated by authentication processing means.
