Abstract:
1. A coordinate input apparatus to select a coordinate position in a coordinate input region due to a true input according to an operator's dominant arm, the coordinate input apparatus comprising: a plurality of detection units including a first sensor unit and a second sensor unit, wherein the first sensor unit is positioned to a right of a person who faces the coordinate input region and the second sensor unit is positioned to a left of a person who faces the coordinate input region; a memory in which dominant arm information, specifying whether the operator is right-handed or left-handed, is registered for the operator prior to the coordinate input region receiving input from the operator; an obtaining unit configured to obtain a plurality of coordinate positions, wherein the obtained coordinate positions are those coordinate positions detected by each sensor unit of the plurality of detection units, wherein the obtained plurality of coordinate positions includes a true input coordinate position input from the operator and at least one erroneous input coordinate position input from the operator, and wherein virtual coordinate positions for the true input coordinate position and the at least one erroneous input coordinate position are obtained; a reading unit configured to read the memory to obtain dominant arm information specifying weather the operator is specified as right-handed or specified as left-handed; a selection unit configured to select, as coordinate position data, coordinate positions obtained by the obtaining unit, wherein, in response to the memory specifying that the operator is right-handed, the selection unit selects, as the coordinate position data, coordinate positions obtained from inputs detected by the first sensor unit such that the coordinate position data includes the true input coordinate position and does not include the at least one erroneous input coordinate position, and wherein, in response to the memory specifying that the operator is left-handed, the selection unit selects, as the coordinate position data, coordinate positions obtained from inputs detected by the second sensor unit such that the coordinate position data includes the true input coordinate position and does not include the at least one erroneous input coordinate position; a determining unit configured to determine the true input coordinate position from the coordinate position data selected by the selection unit; and an output unit configured to output data indicating the determined true input coordinate position as an input coordinate position input from the operator.
