1. An information input device which displays an entry screen including a plurality of entry fields and allows a user to input information in each of the entry fields, the information input device comprising: a display screen to display said entry screen and said plurality of entry fields; a central processing unit configured to generate, when said user selects one of said entry fields, attribute information, said attribute information includes a required attribute relating to how a linguistic element of the selected entry field is visually presented on the display screen; computer memory to store a predetermined tactile pattern corresponding to the required attribute; the central processing unit configured to acquire said tactile pattern corresponding to the required attribute; a tactile pattern output unit having a plurality of tactile pins to output said tactile pattern corresponding to the required attribute added to the selected entry field to allow the user of the information input device to sense by touch the required attribute in parallel with reproduction of the selected entry field; and linguistic information including said plurality of linguistic elements displayed on the display screen; wherein as the attribute of each of a plurality of linguistic elements included in said linguistic information, said attribute information includes a background color at a position of the display screen of said display device where a linguistic element of interest is displayed; wherein said computer memory is configured to store a tactile pattern corresponding to each of background colors at positions where linguistic elements are displayed; and wherein for each of said plurality of linguistic elements, said tactile pattern output unit outputs a tactile pattern corresponding to the background color at a position of the display screen where the linguistic element of interest is displayed as said tactile pattern corresponding to the attribute added to the linguistic element of interest; wherein the central processing unit configured to search for a most-frequent attribute which is an attribute added to the largest number of linguistic elements among said plurality of linguistic elements included in said linguistic information; and wherein in parallel with reading aloud each of a plurality of linguistic elements, said tactile pattern output unit is configured to output said tactile pattern corresponding to an attribute added to the linguistic element of interest when the attribute is not the most-frequent attribute and stops outputting the tactile pattern when the attribute added to the linguistic element is said most-frequent attribute.
