METHOD AND APPARATUS FOR SENSING GESTURE TOWARD TOUCH INPUT DEVICE

摘要

Examples of sensing a gesture with respect to a touch input device are described. For example, a method to sense a gesture may include acquiring a distance between a finger, which may not be in contact with the touch input device, and at least two heat sensing spots on the touch input device. The acquired distances may be compared to identify the shortest distance. The gesture of the finger toward the touch input device may be identified based on the shortest distance being less than a predetermined threshold. The described techniques and examples may improve overall performance of system that may be equipped with the touch input device.

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 by a heating spot of the plurality of heat sensing spots at a variable heat detection frequency 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; and 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.
