Below in conjunction with the accompanying drawing in the present invention, the technical scheme in the invention process is carried out to clear, complete description.With the example that is operating as of finger, the present invention is described in detail below.
In the time of system initialization, create the sampling point information array of one group of operation trace, be used for preserving the current system time of finger at X coordinate, Y coordinate and the sampled point of the sampled point of the operation trace of interface of mobile terminal.
Accompanying drawing 2 has been shown the schematic diagram of collecting the sampled point of finger manipulation track on base instruction collection basis.Initialization sampling point information data after receiving finger to press message, start to collect the sampled point of finger manipulation track; When receive finger mobile messaging after, according to regular time interval sampled point is sampled, sampled point X, Y coordinate can be kept in sampling point information array, meanwhile, this array is also preserved the time value of sampled point current system clock.Wherein, some P1, P2, P3, P4 and P5 are sampled point, and some P1 is initial sampled point, and other point is the point that need to ignore.
Accompanying drawing 3 has been described the operation trace of utilizing fault-tolerant value to ensure finger in the time of calculating sampling point coordinate can meet the lopcus function calculating.In practical operation, the movement of finger on touch sensitive screen can not conform to the lopcus function of absolute standard, can have shake and error.In order to realize anti-shake and error correction, shake within the specific limits and error can be thought and still meet the form of expression of lopcus function.Therefore, in invention, introduce fault-tolerant value σ, the fault-tolerant scope of the X coordinate of sampled point is (X-σ, X+ σ), the fault-tolerant scope of Y coordinate is (Y-σ, Y+ σ), fault-tolerant region { (X-σ, X+ σ), (Y-σ, Y+ σ) } can be referred to as fault-tolerant rectangle.If current rectangle is that unit calculates by a pixel, should there be 4 σ
2individual pixel.This group sample point coordinate data successively substitution lopcus function are calculated, introduced error of calculation γ herein.In the time of f (Y)-f (X)=z ± γ, this sampled point meets current lopcus function.(determine according to accuracy of identification when there are several points in one group of sampled point, an if total n point, the scope of several points can be from 1 to 1/2*n not etc., n is greater than 1 natural number) depart from γ scope but meet fault-tolerant rectangle { (X-σ, X+ σ), (Y-σ, Y+ σ) }, this sampled point is effective; Otherwise this group sampled point does not meet current lopcus function.
Accompanying drawing 4 has been described the general illustration of identifying operation track.Each group sampled point all comprises certain fault-tolerant region, to ensure discrimination.The operation trace that can identify all should have mark fixing, the overall situation.These marks should provide as the additional parameter of operational order.Below provide circle, the recognition methods of straight line and elliptical path:
(1) flow process of identification circular trace is as follows: the sample point coordinate of circular trace need to meet X
2+ Y
2=r
2the lopcus function of ± γ (r is radius of a circle, and γ is error).When after this lopcus function of coordinate substitution of first sampled point, can calculate r
2value.Follow-up sampled point will meet
can meet circular trace curve.If the some points in current sampling point array meet the scope of fault-tolerant rectangle, return to the mark of circular trace, concrete mark can be set according to user.
(2) flow process of identification straight path is as follows: the coordinate of linear pattern tracing point need to meet lopcus function Y-KX=0 ± γ, and (γ is error) wherein K is certain constant value, represents slope.Gather after initial point coordinate, when subsequent point coordinate meets this lopcus function in fault-tolerant scope, return to the mark of straight path, concrete mark can be set according to user.
(3) flow process of identification elliptical path is as follows: the function of elliptical path is
(a is oval major axis, and b is oval minor axis, and γ is error).The present invention can be, but not limited to support to detect the ellipse of major axis and the satisfied following three kinds of relations of minor axis, b=1/2*a, b=1/4*a, b=3/4*a, the elliptical orbit function ratio of additional this relation is easier to calculate the value of major axis and minor axis, and consider fault-tolerant value, the oval scope that can identify can suitably increase.Successfully identifying after elliptical path, returning to the mark of elliptical path, concrete mark can be set according to user.
It should be noted that the more recognition methods of multi-trace curve, as long as the sampling point information array gathering meets lopcus function, seldom repeats at this.
Be deposited into a suitable structure using the shape of the operation trace of identification as overall identification, as the first parameter of operational order.
Accompanying drawing 5 has been described and has been calculated the speed of current finger manipulation track and the schematic diagram of direction attribute.When sampled point is sampled, gathered system time simultaneously, utilize system time, and obtain the movement velocity attribute of current operation track by calculating the absolute distance of these sampled points.
Within the same time cycle, (allow the error in certain limit), if every 2 distances of the current sampling point information array gathering keep L ± γ, (L is
(absolute distance that L is point-to-point transmission, γ is error), so current motion is uniform motion; If absolute distance keeps successively decreasing gradually between two sampled points, prove that current motion is retarded motion, it should be noted that, retarded motion needn't ensure to successively decrease or uniformly retarded motion according to rule; If absolute distance keeps increasing progressively gradually between two sampled points, prove that current motion is accelerated motion, it should be noted that, accelerated motion needn't ensure it is uniformly accelerated motion.Meanwhile, due to the absolute distance having calculated between every two sampled points,
can think approximate move distance summation, and
(the system time value that Ti is each sampled point) for time of finger manipulation and.These movement properties can be expressed as " acceleration " (SPEEDUP), " deceleration " (SPEEDDOWN) etc.Deposit in using run duration, move distance and movement velocity attribute as moving parameter information in this suitable structure, as the second parameter of this operational order.
In the time that finger lifts, system may be defined as form of message by the operational order after identification and issues, and also may be defined as other operational orders.For example can define an overall operational order (MOUSEMOVEINFO).When completing after one group of sampled point identification, system issues operational order.
It should be noted that, user can set in advance operation corresponding to different operational orders as required.By this operational order, system can be carried out next step operation according to operation trace type.For example recognizing after circular trace, can carry out the rotation of 360 degree to interfaces windows; Receive after elliptical path information, can carry out page turn over operation to interfaces windows; Receive after parabolic path, can carry out gradually large or gradually little operation to interfaces windows.Accelerate after operational order when receiving, can carry out analog physical acceleration and have the interface special efficacy of certain inertia interfaces windows.
