【Task】 With the conventional dot pattern technology, the latitude / longitude information or related information cannot be obtained from the curved surface, and the coordinate information and / or code information from the vicinity of the line drawn on the map or drawing is obtained. In order to obtain information related to reading and line segments, a region including the line segment must be defined by a human hand, and a dot pattern relating the information must be formed in the region. However, the labor, time, and cost become enormous, and when the line segments are adjacent to each other, there is a problem that a sufficient area cannot be secured and information cannot be accurately defined in the line segments. [Solution] By connecting a plurality of stream dot patterns with less moiré, which are striped periodic patterns, formed based on a predetermined rule to form a strip shape, it can be applied to various line segments such as curved bodies, maps, drawings, etc. An information input medium capable of defining accurate latitude / longitude information and coordinate information can be created.
