Method and apparatus of recognizing gesture with untouched way

A method of generating a control signal, comprising:

• storing sensing information of a sensor in a case where the sensing information is obtained by sensing an object within a preset distance from the sensor;
• recognizing a gesture from the stored sensing information;
• and
• generating a control signal corresponding to the recognized gesture,
• wherein said storing of sensing information stores the sensing information obtained by the sensor during a preset time after the sensor senses an object within the preset distance.

An apparatus of recognizing a gesture, comprising:

• a distance calculating unit for calculating whether sensing information of a sensor is obtained by sensing within a preset distance from the sensor;
• a storing unit for storing the sensing information in a case where the sensing information of the sensor is obtained by sensing within the preset distance from the sensor;
• and
• a gesture recognizing unit for recognizing a gesture from the stored sensing information,
• wherein the storing unit stores the sensing information obtained from the sensor during a preset time after the sensor senses an object within the preset distance.
