[embodiment]
The invention provides a kind of touch screen zooming command method, it utilizes the single-point contact that do not frame out to produce the Scale command that the information table of continuous path shows screen picture.
Its specific embodiments comprises the steps:
One Touch Screen is provided;
There is provided the processing unit connecting aforementioned Touch Screen, it can receive and store contact trace P1, P2, P3, P4 of a contact on Touch Screen.。。PN, the position of each point is (X1, Y1), (X2, Y2), (X3, Y3), (X4, Y4).。。（XN，YN）；
The application software being installed on processing unit is provided, it can with time sequencing, choose first group of contact point P1, P2, P3 on contact trace, the home position of ordering first group of contact point place circumference is (XC1, YC1), its radius is R1, equal to condition to the distance in the center of circle with each point circumferentially, draw system of equations as shown in Figure 2, thus can first curvature radius R1 be calculated.Second group of contact point P2, P3, P4, the home position of second group of contact point place circumference is (XC2, YC2), its radius is R2, equal to condition to the distance in the center of circle with each point circumferentially, draw system of equations as shown in Figure 3, thus the second radius R 2 can be calculated.Then more each radius, if the second radius R 2 is greater than the first radius R 1, then performs the order of being amplified by screen picture, if the second radius R 2 is less than the first radius R 1, then performs the order reduced by screen picture.
At above-mentioned touch screen zooming command method, the multiple wherein at every turn zoomed in or out is the ratio of second curvature radius R2 and first curvature radius R1, also can make to zoom in or out fixing multiple at every turn.
In a contact trace, multiple radius can be drawn, R1, R2, R3, R4, R5, the operation zoomed in or out can be formed continuously like this.In addition, in order to prevent maloperation, occur single when zooming in or out order, this individual command can perform.That is, if the first radius R 1> second radius R 2> the 3rd radius R 3, then perform the order of image down; If the first radius R 1> second radius R 2< the 3rd radius R 3=> is failure to actuate; If the first radius R 1< second radius R 2> the 3rd radius R 3=> is failure to actuate; If the first radius R 1< second radius R 2< the 3rd radius R 3, then perform the order of Nonlinear magnify.Further, in order to prevent maloperation, the curvature data of contact trace two ends certain length is not as the Scale command representing screen picture.Wherein when radius-of-curvature is greater than length-specific, perform the order of moving screen image, described Touch Screen is provided with detection initialization system, and operator can set the aforementioned length-specific radius-of-curvature facilitating it to operate.
Below often organizing contact point is three, concyclicly determines radius according to 3.And essence of the present invention is the order of zoomed image according to the convert information of contact point radius-of-curvature each on contact trace.As other embodiment, often group can also get more contact point, determine thus closer to radius-of-curvature, and without size especially big or special little radius-of-curvature.Can also get the point do not overlapped, if first group of contact point is P1, P2, P3, second group of contact point is P8, P9, P10.On contact trace, have point of contact is chosen by interval duration of contact, and the such as time interval is 0.1 second.Be accustomed to difference according to operator, can also choose in contact trace fixed length interval by contact point, such as fixed length interval is 1 millimeter.
For above-mentioned touch screen zooming command method, wherein the most intuitively mode of operation on screen, draw involute urve (refers to Fig. 4 exactly, forefinger Touch Screen), then perform the order of Touch Screen Nonlinear magnify continuously, screen is oppositely drawn involute urve and (refers to Fig. 5, forefinger Touch Screen), then perform the order of Touch Screen image down continuously.
As other embodiment of the present invention, clockwise camber line can be drawn on screen, then perform the order of Touch Screen Nonlinear magnify, screen is drawn the order that counterclockwise camber line then performs Touch Screen image down.Or, screen is drawn the order that clockwise camber line then performs Touch Screen image down, screen is drawn the order that counterclockwise camber line then performs Touch Screen Nonlinear magnify.This kind of mode operates more convenient, and not easily makes mistakes.
In addition, as other embodiment of the present invention, can also be (do not frame out) continuously to draw other figure and represent the order that screen picture amplifies on Touch Screen.As first drawn a hyphen, holding contact contacts, and after making a short pause, then draws a long horizontal stroke, represents and amplifies order; First draw a long horizontal stroke, holding contact contacts, and after making a short pause, then draws a hyphen, represents and reduces order.For another example draw " a " and represent amplification, draw " s " expression and reduce.For another example continuously picture represents amplification anyhow, draws vertical horizontal continuously and represents and reduce.
