Abstract
An air conditioning device for a vehicle and a method of controlling the same are provided. The air conditioning device includes a touch input unit which is configured to be touched, rotated by 360 degrees, and dragged by a user. A touch sensor unit includes three channel regions formed by trisecting a rotational region of 360 degrees and is configured to detect capacitance in accordance with touch areas of a first channel, a second channel, and a third channel at predetermined positions in the three channel regions. Three channel signal output units output signals from the respective channels in accordance with the recognized capacitance.
