Following steps S101 is included to step S104：
S101, the dot matrix that N × N number of infrared sensor is formed is mapped to the touch-screen of M × M pixel.
In embodiments of the present invention, N and M is the natural number more than 1, and N is not more than M.By N × N number of infrared sensor
The dot matrix of composition maps to the touch-screen of M × M pixel, and N equal portions, every part of M/N will be divided into equivalent to by every M pixel
Individual pixel, then, in the dot matrix that N × N number of infrared sensor is formed, each row or first infrared sensing per a line dot matrix
Device corresponds to the M/N pixel of respective column or corresponding line in M × M pixel, and second infrared sensor corresponds to M × M
The 2M/N pixel ... ... of respective column or corresponding line in pixel, n-th infrared sensor are corresponded in M × M pixel
The m-th pixel of respective column or corresponding line.For example, the dot matrix formed for 50 × 50 infrared sensors, is mapped
To the touch-screen of 300 × 300 pixels, then 50 equal portions are divided into by 300, are red by 50 × 50 at interval of 6 pixels
An infrared sensor in the dot matrix that outer sensor is formed is corresponding.Specifically, the dot matrix that 50 × 50 infrared sensors are formed
In each row or corresponding 300 × 300 pixels of the 1st infrared sensor per a line dot matrix in respective column or corresponding line
6th pixel, the 2nd infrared sensor correspond to respective column or the 12nd pixel of corresponding line in 300 × 300 pixels

N × y, x and y are respectively interpolation multiple.
For example, the dot matrix formed for 50 × 50 infrared sensors maps to the touch of 3000 × 3000 pixels
Screen, because 50 and 3000 are separated by 60 times, 50 can be considered as and be much smaller than 3000, in this way, directly by 50 × 50 infrared sensor structures
Into dot matrix map to the touch-screen of 3000 × 3000 pixels after, the pixel that is mapped very little (only 50, relative to
3000 very little), then, the sliding effect finally simulated is not smooth, feels it is a card to user, and experience is not
It is good.In embodiments of the present invention, the dot matrix that 50 × 50 infrared sensors are formed such as is mapped into 3000 × 3000 pixels
Touch-screen, then be divided into 50 equal portions by 3000, the dot matrix formed at interval of 60 pixels by 50 × 50 infrared sensors
In an infrared sensor it is corresponding, i.e. each row in the dot matrix that 50 × 50 infrared sensors are formed or per a line dot matrix
Corresponding 3000 × 3000 pixels of the 1st infrared sensor in the 60th pixel of respective column or corresponding line, the 2nd is red
120th pixel ... ... of respective column or corresponding line in corresponding 3000 × 3000 pixels of outer sensor, it is the 50th infrared
3000th pixel of respective column or corresponding line in corresponding 3000 × 3000 pixels of sensor.If on touch-screen 3000
50 × 50 pixels will being mapped in × 3000 pixels carry out interpolation processing, for example, according to 10 times of interpolation multiple
Carry out interpolation, then equivalent to it is each row or per a line 3000 pixels in, in the 1st pixel to the 60th pixel
In at interval of 6 pixels insert a pixels, i.e., insert 10 pixels altogether into the 60th pixel in the 1st pixel
Point, a pixel is inserted at interval of 6 pixels into the 120th pixel in the 61st pixel, i.e., in the 61st picture
Vegetarian refreshments inserts 10 pixels ... ... altogether into the 60th pixel, in the 2941st pixel into the 3000th pixel
A pixel is inserted at interval of 6 pixels, i.e., inserts 10 pictures altogether into the 300th pixel in the 2941st pixel
Vegetarian refreshments, in this way, 500 pixels are inserted altogether, it is every in 3000 × 3000 pixels plus 50 pixels being mapped
A line or each row are 550 pixels altogether, relative to 50 pixels before no interpolation, are simulated again in the mapped
Gesture is slided, and can greatly improve fluency, reduces the sensation of a card.
S102, capture the gesture on the screen formed in N × N dot matrix infrared sensor.
In embodiments of the present invention, when finger is sliding on the screen that dot matrix infrared sensor is formed, array sensor is put
In each infrared sensor can capture sensing data；With finger slip and each infrared sensor capture, i.e.,
The gesture on the screen formed in N × N dot matrix infrared sensor (dot matrix that N × N number of sensor is formed) can be captured.
Because certain user from a place by finger when sliding into another place, start bit may be immediately fallen back to
Put.According to being ready for user, the short time returns to original position and should not be identified.If identification, is exactly to misidentify.In order to
Prevent the generation of this situation, in embodiments of the present invention, capture dot matrix infrared sensor form screen on gesture it
Afterwards, methods described also includes：Pass through backoff algorithm, processing misrecognition action.Specifically, point of the gesture in N × N can first be judged
Glide direction when sliding into target location from original position on the screen that battle array infrared sensor is formed, then, if when default
In, for example, in 800ms, the gesture is back to original position from target location along the direction opposite with glide direction, then mistake
Filter the gesture and be back to thing caused by the original position from the target location along the direction opposite with the glide direction
Part.Once this kind of event is filtered, then follow-up system does not have the response of opponent's gesture, from without sliding effect.
