Pen and touch input system and controller

Pen and touch input system or controller

A touch pressure sensitivity correction method may be provided that includes: defining a plurality of reference points on a touch sensor panel; generating a reference data for a capacitance change amount sensed by applying the same pressure to the plurality of reference points; generating an interpolated data corresponding to a capacitance change amount for a random point present between the plurality of reference points; calculating, on the basis of the reference data and interpolated data, with respect to the reference points and the random point respectively, a correction factor for correcting a sensitivity of a touch input device to a target value; and correcting uniformly for the touch pressure sensitivity of the touch input device by applying the calculated correction factor to each corresponding point.

Touch pressure sensitivity correction method and computer-readable recording medium

A sensitivity compensation method of a touch input device sensing a touch pressure may be provided. The sensitivity compensation method includes: detecting a capacitance change amount by applying a pressure to a plurality of points defined on a touch sensor panel; generating a raw data for the capacitance change amount of the defined point; generating a decimal value data for each of the sets by dividing a data value within the set by a maximum value within the set; calculating an average value of each defined point; generating a representative value data by calculating a value corresponding to all the points of the touch sensor panel; calculating a balance factor on the basis of the representative value data; and compensating for a touch pressure sensitivity of the touch input device by using the balance factor.

Method for calibrating sensitivity of touch input devices sensing touch pressure, and computer readable recording medium

A sensitivity compensation method of a touch input device sensing a touch pressure may be provided. The sensitivity compensation method includes: defining a plurality of reference points spaced apart from each other on a touch sensor panel; generating a reference data corresponding to a capacitance change amount sensed by applying a predetermined pressure to the plurality of reference points; generating, on the basis of the reference data, an interpolated data corresponding to a capacitance change amount for a random point present between the plurality of reference points; calculating, on the basis of the generated reference data and interpolated data, with respect to the reference point and random point respectively, a compensation factor for compensating a sensitivity of the touch input device to a target value; and compensating uniformly for the sensitivity of the touch input device by applying the calculated compensation factor to each corresponding points.
