The device that the embodiment of the present invention is provided, it realizes principle and the technique effect of generation and aforementioned side
Method embodiment is identical, for briefly describing, and the not mentioned part of device embodiment part, refer to aforementioned side
Corresponding contents in method embodiment.
The above-mentioned object actuation means for touch-screen equipment provided by the embodiment of the present invention, Yong Hutong
Crossing manipulation touch-control icon and can realize the control to destination object, not only control action is accurate, Er Qieyong
The observation sight line of destination object is difficult to be blocked by hands by family.
Corresponding to the touch-control icon mentioned by said method and device, may refer to the one shown in Fig. 3
Destination object and the position relationship schematic diagram of touch-control icon.
For above-mentioned a kind of object control method for touch-screen equipment and device, pass through touch-control with user
As a example by icon (can be referred to as UI icon) realizes the translation transformation of object module, it is referred to down
Process of stating realizes:
1, after having detected that model is selected, determine each apex coordinate of this object module, and calculate
The minimum outer bounding box (being equivalent to the destination object size in above-described embodiment) of object module: according to this
Each apex coordinate of object module determines X-axis maximum and minima in apex coordinate, and it is exhausted that it differs from
To the length that value is this model.In like manner, asking Y-axis maximum and minima in apex coordinate, it is exhausted that it differs from
To the width that value is this model.Formula used can be found in as follows:
xmin=Min (x0…xi)
xmax=Max (x0…xi)
ymin=Min (y0…yi)
ymax=Max (y0…yi)
W=| xmax-xmin|
H=| ymax-ymin|
Wherein, x0…xiFor threedimensional model 0 ... i summit X-coordinate, y0…yiFor threedimensional model 0 ... i pushes up
Point Y coordinate, W is the length of threedimensional model, and H is the width of threedimensional model.
2, the center of UI icon is determined according to following formula:
Wherein, (XUI, YUI) it is the center point coordinate of UI icon, (XM, YM) it is object module
Center point coordinate.
3, on the above-mentioned UI icon center calculated, UI icon is shown.
4, calculate finger to click on contact point on UI icon and (be to the side-play amount of model center point
Offset distance in above-described embodiment):
(Vx, Vy)=(XT, YT)—(XM, YM)
Wherein, (XT, YT) it is finger contact position coordinate on touch screen, (Vx, Vy) it is offset vector.
5, by dragging UI icon, model is carried out parallel transformation and (be equivalent to touching in above-described embodiment
Control instruction), click on UI icon every time and be both needed to calculate side-play amount, when translating UI icon, according to touch-control
The distance of some movement adds skew and measures the position (controlling party being equivalent in above-described embodiment of model
Formula).The formula that UI icon moves according to contact is as follows:
Model makes the position calculation formula after corresponding translation transformation such as along with the translation of UI icon
Under:
Wherein, (XTc, YTc) be finger click on UI icon contact coordinate, (XUIn, YUIn) it is
Coordinate after UI conversion, (XMn, YMn) it is the coordinate after model moves.
It should be noted that above-mentioned listed formula is only a kind of algorithm of signal, can set as touch screen
The mode of standby acquiescence.Other algorithm also can be used during realizing to determine object module and touch-control icon
Position relationship.Additionally, for rotation transformation destination object carried out by touch-control icon and scaling
The control principles such as conversion are similar to above-mentioned example, do not repeat them here.
