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

Abstract

The present invention relates to a method for calibrating the sensitivity of touch input devices sensing touch pressure with respect to a plurality of sets of touch input devices, the method comprising the steps of: detecting a capacitance variation by applying pressure to a plurality of points defined in touch sensor panels, which are provided on touch input devices, with respect to the plurality of sets of the touch input devices; generating raw data, for each set, for the capacitance variation of the defined points on the basis of the detected capacitance variation; generating fractional value data for each set, by dividing a data value within each set by the maximum value within each set; calculating the mean value per defined point on the basis of the fractional value data generated in each set; generating representative value data by calculating values corresponding to total points of the touch sensor panels on the basis of the mean value per point; calculating a coefficient on the basis of the representative value data; and calibrating the touch pressure sensitivity of the touch input devices by using the coefficient.

Description

technical field [0001] The present invention relates to a sensitivity correction method of a touch input device for detecting touch pressure and a computer-readable recording medium, and more particularly relates to a touch input device for detecting touch pressure capable of uniformly correcting the touch pressure sensitivity of a touch sensor panel A sensitivity correction method and a computer-readable recording medium recording a program for executing the same. Background technique [0002] Various input devices for operating computing systems, such as buttons, keys, joysticks, and touch screens, are being developed and utilized. Among them, the touch screen has attracted the most attention because of its advantages such as ease of operation, miniaturization of the product, and simplification of the manufacturing process. [0003] The touch screen may constitute a touch surface of a touch input device including a touch sensor panel, which may be a transparent panel with...
