摘要： Provided are an apparatus for and method and medium of adaptively setting a reference sensing boundary of a touch sensor. The apparatus for adaptively setting a reference sensing boundary includes a reference sensing boundary setting unit adaptively setting a reference sensing boundary of a capacitance using a signal generated by a reference touch sensor; a determination unit determining whether or not a value measured by a device control touch sensor controlling a device to which the reference touch sensor is attached is within the set reference sensing boundary, by sensing a change in the capacitance; and an output unit outputting the measured value if the determination result indicates that the measured value is within the reference sensing boundary. Accordingly, the reference sensing boundary of the touch sensor is automatically recalculated without a user's intervention and a sensitivity and threshold of the touch sensor are adaptively changed so that the operational reliability of the touch sensor can be enhanced.
