Abstract: A coordinate input device includes an operation detecting unit for detecting an input operation performed by an operation body and a calculation unit for computing a calculation result from the input operation, wherein, in a case where the input operation detected by the operation detecting unit continues for a predetermined time, the calculation unit acquires a first position coordinate at a first time and a second position coordinate at a second time is detected after the first time, calculates an input vector from the first position and directed toward the second position, calculates a movable distance between an end and another end of the operation detecting unit on a line connecting the first position and the second position, and computing an output vector by increasing a correction value for correcting a value of the input vector so that the shorter the movable distance, the larger the correction value is.
