Below in conjunction with the accompanying drawing among the present invention, the technical scheme in the invention process is carried out clear, complete description.With the example that is operating as of finger, the present invention is described in detail below.
When 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 the X of the sampled point of the operation trace of interface of mobile terminal coordinate, Y coordinate and sampled point.
Accompanying drawing 2 has been showed the synoptic diagram of collecting the sampled point of finger manipulation track on base instruction collection basis.Receive finger press message after initialization sampling point information data, begin to collect the sampled point of finger manipulation track; After receiving the finger mobile messaging, at interval sampled point to be sampled according to regular time, sampled point X, Y coordinate can be kept in the sampling point information array, and simultaneously, this array is also preserved the time value of the current system clock of sampled point.Wherein, some P1, P2, P3, P4 and P5 are sampled point, and some P1 is initial sampled point, the point of other point for ignoring.
Accompanying drawing 3 has been described the operation trace of utilizing fault-tolerant value to guarantee finger when the calculating sampling point coordinate can satisfy the lopcus function that calculates.In the practical operation, finger moving 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 the form of expression that still meets lopcus function.Therefore, introduce fault-tolerant value σ in invention, the fault-tolerant scope of the X coordinate of sampled point is (X-σ, X+ σ), and the fault-tolerant scope of Y coordinate is (Y-σ, Y+ σ), and fault-tolerant zone { (X-σ, X+ σ), (Y-σ, Y+ σ) } can be referred to as fault-tolerant rectangle.Current rectangle should have 4 σ as if being that unit calculates by a pixel
2Individual pixel.This group sample point coordinate data substitution lopcus function are successively calculated, introduced error of calculation γ herein.When f (Y)-f (X)=z ± γ, this sampled point satisfies current lopcus function.Some spots in one group of sampled point, occurs and (determine that according to accuracy of identification if a total n point, then the scope of some spots can not wait from 1 to 1/2*n, n is for greater than 1 natural number) depart from the γ scope but satisfy fault-tolerant rectangle { (X-σ, X+ σ), (Y-σ, Y+ σ) }, then this sampled point is effective; Otherwise this group sampled point does not satisfy 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 zone, to guarantee discrimination.The operation trace that can discern all should have sign fixing, the overall situation.These signs 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 satisfy X
2+ Y
2=r
2The lopcus function of ± γ (r is a radius of a circle, and γ is an error).Behind this lopcus function of coordinate substitution of first sampled point, can calculate r
2Value.Follow-up sampled point will satisfy
Can meet the circular trace curve.If the some points in the current sampling point array satisfy the scope of fault-tolerant rectangle, then return the sign of circular trace, concrete sign can be set according to the user.
(2) flow process of identification straight path is as follows: the coordinate of linear pattern tracing point need satisfy lopcus function Y-KX=0 ± γ, and (γ is an error) wherein K is certain constant value, the expression slope.After gathering the initial point coordinate, when the subsequent point coordinate satisfies this lopcus function in fault-tolerant scope, then return the sign of straight path, concrete sign can be set according to the user.
(3) flow process of identification elliptical path is as follows: the function of elliptical path is
(a is a long axis of ellipse, and b is oval minor axis, and γ is an error).The present invention can but be not limited to support to detect the ellipse that major axis and minor axis satisfy following three kinds of relations, b=1/2*a, b=1/4*a, b=3/4*a, the elliptical orbit function of additional this relation is than the value that is easier to calculate major axis and minor axis, and consider fault-tolerant value, the oval scope that can discern can suitably increase.After successfully discerning elliptical path, then return the sign of elliptical path, concrete sign can be set according to the user.
Need to prove that the more recognition methods of multiple trace curve as long as the sampling point information array of gathering satisfies lopcus function, is seldom given unnecessary details at this.
The shape of operation trace of identification is deposited into a suitable structure as overall identification, as first parameter of operational order.
Accompanying drawing 5 has been described the speed of calculating current finger manipulation track and the synoptic diagram of direction attribute.Owing to when sampled point is sampled, gathered system time simultaneously, utilized system time, and obtain the movement velocity attribute of current operation trace by the absolute distance that calculates these sampled points.
(allow the error in the certain limit) in the identical time cycle, (L is if per 2 distances of the current sampling point information array of gathering keep L ± γ
(L is the absolute distance of point-to-point transmission, and γ is an error), so current motion is a uniform motion; If absolute distance keeps successively decreasing gradually between two sampled points, prove that then current motion is retarded motion, need to prove that retarded motion needn't guarantee to successively decrease or uniformly retarded motion according to rule; If absolute distance keeps increasing progressively gradually between two sampled points, prove that then current motion is accelerated motion, need to prove accelerated motion needn't guarantee it is uniformly accelerated motion.Meanwhile, owing to the absolute distance that has calculated between per two sampled points, then
Can think the move distance summation that is similar to, and
(Ti is the system time value of each sampled point) then for time of finger manipulation and.These movement properties can be expressed as " acceleration " (SPEEDUP), " deceleration " (SPEEDDOWN) etc.Run duration, move distance and movement velocity attribute are deposited in this suitable structure as moving parameter information, as second parameter of this operational order.
When finger lifted, the operational order after system will discern may be defined as form of message and issues, and also may be defined as other operational orders.For example can define the operational order (MOUSEMOVEINFO) of an overall situation.After finishing one group of sampled point identification, system issues operational order.
Need to prove that the user can set in advance the corresponding different operation of different operational orders as required.By this operational order, system can carry out next step operation according to the operation trace type.For example after recognizing circular trace, can carry out the rotation of 360 degree to interfaces windows; After receiving elliptical path information, can carry out page turn over operation to interfaces windows; After receiving parabolic path, can carry out gradually big or gradually little operation to interfaces windows.After receiving the acceleration operational order, can carry out the interface special efficacy that analog physical quickened and had certain inertia to interfaces windows.
