Abstract
An apparatus and method to recognize a moving direction of gesture are provided. A final moving direction of gesture is determined using the number of intersecting points based on output values from one or more sensors disposed in up, down, left, right directions and a code of an accumulated sum. Thus, a moving direction of target (hand) that moves on the sensors is recognized more accurately. The apparatus to recognize a moving direction of a gesture includes first to fourth sensor disposed at a position that is north, south, west, and east from a center; and a controller configured to identify a number of intersecting points based on output values of the first sensor, the second sensor, the third sensor and the fourth sensor and to estimate a moving direction of the gesture according to the number of the intersecting points.
