Claim Text:
1. A method for sensing a gesture towards a touch input device, the method comprising: detecting, by each of a plurality of heat sensing spots on the touch input device, a heat intensity from a finger, wherein the finger is not in contact with the touch input device, and the heat intensity is detected at a variable frequency by a heat sensing spot of the plurality of heat sensing spots, wherein the variable frequency for the detecting is associated with a distance of the finger from the heat sensing spot; calculating, by a processor, a distance of the finger from each of the plurality of heat sensing spots, based on the heat intensity detected by each of the heat sensing spots; determining, by the processor, a shortest distance among the calculated distances by comparing the calculated distances; identifying, by the processor, the gesture of the finger toward the touch input device, in response to the shortest distance being less than a predetermined distance threshold, comparing, by the processor, a first distance of the finger from a first heat sensing spot with a second distance threshold; increasing, by the processor, the variable frequency of the first heat sensing spot in response to the distance of the finger from the first heat sensing spot being less than the second distance threshold; and decreasing, by the processor, the variable frequency of the first heat sensing spot in response to the distance of the finger from the first heat sensing spot being greater than the second distance threshold.
