主权项

1. A device for recognizing a gesture based on a direction of movement of an object, the device comprising:
a memory configured to store previous directional information that indicates a first direction of movement of the object in which the object moves between a previous position and a current position; a sensor configured to sense the movement of the object between positions and output sensor data that indicates the movement of the object between positions; and a processor configured to determine current directional information that indicates a second direction of movement of the object in which the object moves between the current position and a next position based on the sensor data, to update a variable corresponding to a predetermined gesture by increasing or decreasing the variable based on an update value being assigned to a transition between the first direction of movement of the object indicated by the previous directional information stored in the memory and the second direction of movement of the object indicated by the current directional information, and to recognize the gesture by determining, based on the variable, whether the sensed movement corresponds to the predetermined gesture by comparing the variable to a predetermined threshold value.
