7. An input apparatus inputting a sequence of characters by sequentially selecting each character by using a pointer manipulated by a user, wherein only one of the characters, selected from a plurality of two-dimensional tables, each of the two-dimensional tables including a plurality of two-dimensionally arranged candidate characters, is displayed on a display apparatus at one time and the plurality of candidate characters are arranged in a form of a user-recognized character array, comprising: a pointer movement detection part detecting movement of the pointer manipulated by the user; a scoped character replacement part replacing a currently displayed character with another character of the plurality of candidate characters; and a scoped character determination part determining a scoped character as an input character by conducting a coordinate determination operation based on combinations of whether vertical and/or horizontal shift amounts between a start position and an end position of the pointer detected by the pointer movement detection part are non-negative or non-positive, wherein the coordinate determination operation determines a movement direction of the position and one of the plurality of two-dimensional tables based on a first combination of whether the vertical and/or horizontal shift amounts are non-negative or non-positive and further determines a manipulation stage of the user based on a second combination of whether the vertical and/or horizontal shift amounts are non-negative or non-positive, and wherein the manipulation stage includes a manipulation continuation phase, a manipulation completion phase and an error phase, and wherein if the coordinate determination operation determines that the manipulation stage is in the manipulation continuation phase, the coordinate determination operation stores coordinate data of the end position, and if the coordinate determination operation determines that the manipulation stage is in the manipulation completion phase or the error phase, the coordinate determination operation clears the stored coordinate data of the end position.

The input apparatus as claimed in claim 7 , wherein the user knows the arrangement of the user-recognized character array in advance.
