Abstract
A force based touch interface device comprising a touch substrate, a torsion preventing structure for preventing torsion of the touch substrate by an externally-applied force touch, a plurality of sensors for measuring the force touch applied to the touch substrate at different positions, an input device for applying the force touch onto the touch substrate, and a controller for measuring force data using the plurality of sensors when the force touch is applied onto the touch substrate, for estimating force data for symmetrical points for touch points to which the force touch is applied using the measured force data, and for comparing the measured force data and the estimated force data with ideal force data to generate a calibration matrix for correcting a process error.
