Embodiment
For making goal of the invention of the present invention, feature, advantage can be more obvious and understandable, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, and not all embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
A kind of method that the embodiment of the present invention provides simulate to slide, described method comprises: the touch-screen dot matrix that N × N number of infrared sensor is formed being mapped to M × M pixel, and described N and M is the natural number being greater than 1, and described N is not more than described M; Be captured in the gesture on the screen of described dot matrix infrared sensor formation; Calculate the described gesture distance d ' that during sliding distance d, correspondence is slided on the touch-screen of described M × M pixel on the screen that described dot matrix infrared sensor is formed; Respond the distance d ' slided on the touch-screen of described M × M pixel.The device that the embodiment of the present invention also provides corresponding simulate to slide and a kind of mobile terminal.Below be described in detail respectively.
Refer to accompanying drawing 1, be the realization flow of the method for the simulate slip that the embodiment of the present invention one provides, its executive agent can be the mobile terminal such as smart mobile phone, panel computer.The method that the simulate of accompanying drawing 1 example is slided mainly comprises the following steps S101 to step S104:
S101, maps to the touch-screen of M × M pixel by the dot matrix that N × N number of infrared sensor is formed.
In embodiments of the present invention, N and M is the natural number being greater than 1, and N is not more than M.The dot matrix that N × N number of infrared sensor is formed is mapped to the touch-screen of M × M pixel, every M pixel is equivalent to be divided into N equal portions, every part of M/N pixel, then, in the dot matrix that N × N number of infrared sensor is formed, M/N pixel of respective column or corresponding line in corresponding M × M the pixel of first infrared sensor of each row or every a line dot matrix, 2M/N pixel of respective column or corresponding line in second corresponding M × M pixel of infrared sensor, M pixel of respective column or corresponding line in corresponding M × M the pixel of N number of infrared sensor.Such as, for the dot matrix that 50 × 50 infrared sensors are formed, the touch-screen of 300 × 300 pixels to be mapped to, be then divided into 50 equal portions by 300, at interval of 6 pixels namely by an infrared sensor correspondence in the dot matrix of 50 × 50 infrared sensors formations.Particularly, 6th pixel of respective column or corresponding line in the 1st infrared sensor correspondence 300 × 300 pixels of each row in the dot matrix of 50 × 50 infrared sensor formations or often a line dot matrix, 12nd pixel of respective column or corresponding line in 2nd infrared sensor correspondence, 300 × 300 pixels,, the 300th pixel of respective column or corresponding line in the 50th infrared sensor correspondence 300 × 300 pixels.It should be noted that, when M/N is not integer, depending on situation M/N is rounded downwards or round up.Once the dot matrix that N × N number of infrared sensor is formed maps to the touch-screen of M × M pixel, continuous print sensor (Sensor) data transformations that then gesture motion can be produced is continuous print motion event (MotionEvent) data, the data that the touch-screen being equivalent to M × M resolution produces.
When N is much smaller than M, after directly the dot matrix that N × N number of infrared sensor is formed being mapped to the touch-screen of M × M pixel, mapped pixel very little, so, final simulation sliding effect is out not smooth, feels it is a card to user, experiences bad.Therefore, in embodiments of the present invention, interpolation processing can be carried out in the pixel of M × M on touch-screen by mapped N × N number of pixel, make N × N number of pixel become N
1× N
2individual pixel, wherein, N
1=N × x, N
2=N × y, x and y is respectively interpolation multiple.
Such as, dot matrix for 50 × 50 infrared sensors formations maps to the touch-screen of 3000 × 3000 pixels, because 50 and 3000 are separated by 60 times, 50 can be considered as much smaller than 3000, so, after directly the dot matrix that 50 × 50 infrared sensors are formed being mapped to the touch-screen of 3000 × 3000 pixels, mapped pixel (only has 50 very little, relative to 3000 very little), so, final simulation sliding effect is out not smooth, feels it is a card to user, experiences bad.In embodiments of the present invention, dot matrix as formed by 50 × 50 infrared sensors maps to the touch-screen of 3000 × 3000 pixels, then be divided into 50 equal portions by 3000, an infrared sensor correspondence in the dot matrix formed by 50 × 50 infrared sensors at interval of 60 pixels, namely, 60th pixel of respective column or corresponding line in the 1st infrared sensor correspondence 3000 × 3000 pixels of each row in the dot matrix of 50 × 50 infrared sensor formations or often a line dot matrix, 120th pixel of respective column or corresponding line in 2nd infrared sensor correspondence, 3000 × 3000 pixels, 3000th pixel of respective column or corresponding line in 50th infrared sensor correspondence, 3000 × 3000 pixels.If carry out interpolation processing in 3000 × 3000 pixels on touch-screen by mapped 50 × 50 pixels, such as, doubly interpolation is carried out according to interpolation multiple 10, then be equivalent in 3000 pixels of each row or every a line, to the 60th pixel, a pixel is inserted at interval of 6 pixels at the 1st pixel, namely to the 60th pixel, 10 pixels are altogether inserted at the 1st pixel, to the 120th pixel, a pixel is inserted at interval of 6 pixels at the 61st pixel, namely to the 60th pixel, 10 pixels are altogether inserted at the 61st pixel, to the 3000th pixel, a pixel is inserted at interval of 6 pixels at the 2941st pixel, namely to the 300th pixel, 10 pixels are altogether inserted at the 2941st pixel, so, altogether insert 500 pixels, add 50 mapped pixels, in 3000 × 3000 pixels, every a line or each row are 550 pixels altogether, relative to 50 pixels before not having interpolation, simulate gesture in the mapped again to slide, greatly can improve fluency, reduce the sensation of a card.
S102, is captured in the gesture on the screen of N × N dot matrix infrared sensor formation.
In embodiments of the present invention, when finger slides on the screen that dot matrix infrared sensor is formed, each infrared sensor in some array sensor can catch sensing data; Along with slip and the catching of each infrared sensor of finger, the gesture on screen that N × N dot matrix infrared sensor (dot matrix that N × N number of sensor is formed) forms can be captured in.
Because certain user is when sliding into another place by finger from a place, reference position may be got back at once.Being ready according to user, the short time gets back to reference position and should not be identified.If identify, be then exactly identify by mistake.In order to prevent the generation of this situation, in embodiments of the present invention, after being captured in the gesture on the screen of dot matrix infrared sensor formation, described method also comprises: by backoff algorithm, and process is identification maneuver by mistake.Particularly, first can judge glide direction when gesture slides into target location from reference position on the screen that the dot matrix infrared sensor of N × N is formed, then, if in Preset Time, such as, in 800ms, described gesture is back to reference position from target location along the direction contrary with glide direction, then filter described gesture and be back to the event that described reference position produces from described target location along the direction contrary with described glide direction.Once this kind of event is filtered, then follow-up system does not have the response of opponent's gesture, thus there will not be sliding effect.
S103, calculates the gesture distance d ' that during sliding distance d, correspondence is slided on the touch-screen of M × M pixel on the screen that N × N dot matrix infrared sensor is formed.
Particularly, as one embodiment of the invention, calculate the gesture distance d ' that during sliding distance d, correspondence is slided on the touch-screen of M × M pixel on the screen that N × N dot matrix infrared sensor is formed and can comprise the steps S1031 and step S1032:
S1031, the distance of straight line formed according to a row infrared sensor any in any point between reference position to target location to N × N number of infrared sensor and described any point respectively with the distance of described N number of dot matrix, calculate the distance d that screen that described gesture forms at N × N dot matrix infrared sensor slides, wherein, target location is the terminal of gesture on the screen that N × N dot matrix infrared sensor is formed during sliding distance d.
S1032, according to formula d '=M × d/D, calculates the distance d ' slided on the touch-screen of M × M pixel, and wherein, D is coverage when any row dot matrix transmits in the dot matrix of N × N number of infrared sensor formation.
For the dot matrix that 4 × 4 infrared sensors are formed, as shown in accompanying drawing 2-a.As shown in accompanying drawing 2-b, suppose that in 4 × 4 infrared sensors, any row infrared sensor dot matrix i.e. 4 infrared sensors are (in figure shown in 4 stains, numbering is respectively 1, 2, 3 and 4, below be called infrared sensor 1, infrared sensor 2, infrared sensor 3 and infrared sensor 4) detect gesture and slide into target location (in figure shown in circle) from reference position (figure blacking triangle shown in), reference position uses d to represent to the distance of target location, coverage when 4 infrared sensors transmit uses D to represent in the drawings, between reference position to target location, in the infrared sensor of any point to 4 × 4, the distance of the straight line that any row infrared sensor (4 infrared sensors) is formed uses Lmin to represent in the drawings, between reference position to target location, any point (in figure shown in a square stain) uses L1 with the distance of 4 infrared sensors respectively, L2, L3 and L4 represents.
Suppose to only have infrared sensor 1 target location to be detected in reference position, reference position is L11 to the distance of infrared sensor 1, and as shown in accompanying drawing 2-c, so reference position can obtain according to trigonometric function formula to the position d1 of a period of time inspection center's point
in kind calculate the d2 in upper figure, distance d=d1+d2 like this.If infrared sensor 1 can't detect target location, just with infrared sensor 2 for coordinate points calculate lengthwise position, and suppose that the sensing range of infrared sensor 1 is symmetrical i.e. d=2 × d1+d3 up and down, supposes the fore-and-aft distance calculated for coordinate points with infrared sensor 2 herein.
After the distance d that the screen that gesture is formed at N × N dot matrix infrared sensor slides calculates, according to formula d '=M × d/D, easily calculate the distance d ' slided on the touch-screen of M × M pixel.
S104, responds the distance d ' slided on the touch-screen of M × M pixel.
From the method that the simulate of above-mentioned accompanying drawing 1 example is slided, owing to the dot matrix that N × N number of infrared sensor is formed can be mapped to the touch-screen of M × M pixel, after gesture on the screen being captured in dot matrix infrared sensor formation, calculate the gesture distance d ' that during sliding distance d, correspondence is slided on the touch-screen of M × M pixel on the screen that dot matrix infrared sensor is formed.Therefore, the screen that technical scheme provided by the invention is formed at dot matrix infrared sensor slides finger, can simulate the toughness message of similar touch-screen, realize being similar to touch-screen every empty sliding function.
