Problems solved by technology

The operation of the touch screen device is to replace the mouse with the finger, but when the finger is operated, the contact point on the touch screen is more jittery than the touch point of the mouse; and in the process of affine transformation of the 3D model, the finger You need to press and hold the 3D model. At this time, your hand will cover a large area of ​​the screen, which may cover the 3D model, which affects the line of sight and the accuracy of the transformation during the affine transformation process.
[0003] For the above-mentioned problems of low accuracy and blocking the user's line of sight brought about by manipulating the model with fingers on the touch screen device, no effective solution has been proposed so far.

Embodiment 1

[0025] see figure 1 Shown is a flow chart of an object manipulation method for a touch screen device, which can be implemented on mobile terminals (such as mobile phones, etc.), computers, and other devices, including the following steps:

[0026] Step S102, monitor whether a target object is selected on the touch screen; wherein, the target object may be a three-dimensional model, or a two-dimensional icon, etc., which will not be repeated here.

[0027] Step S104, if yes, acquire the position information of the target object; the position information may be the coordinates of key points of the target object in the coordinate system of the touch screen, wherein the key points may include: the center point of the target object and / or the position of the target object vertex.

[0028] Step S106, according to the location information of the target object, the touch icon is displayed at a specified position away from the target object; wherein, the specified position may be a de...

Embodiment 2

[0046] Corresponding to the above method, an embodiment of the present invention provides an object manipulation device for a touch screen device, which can be set in a device such as a mobile terminal or a computer. For a structural block diagram, see figure 2 , the device consists of the following modules:

[0047] The monitoring module 21 is configured to monitor whether a target object is selected on the touch screen; wherein, the target object may be a three-dimensional model or a two-dimensional icon or the like.

[0048] The position acquisition module 22 is used to obtain the position information of the target object when the monitoring module 21 detects that the target object is selected; the position information can be the coordinates of the key points of the target object under the coordinate system of the touch screen, wherein the key points Can include: the center point of the target object and / or the vertices of the target object.

[0049] The touch icon displa...

Abstract

The invention provides an object control method and device used for touch screen equipment. The method comprises the following steps: monitoring whether a target object is selected or not in a touch screen; if the target object is selected in the touch screen, obtaining position information of the target object; according to the position information of the target object, displaying a touch icon at an appointed orientation which has a distance from the target object; and when a touch instruction for the touch icon is received, controlling the target object according to the touch instruction. Accuracy for controlling the target object with fingers by a user on touch equipment is improved, and the problem that the sight of the user is blocked by the fingers is solved.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular, to an object manipulation method and device for a touch screen device. Background technique [0002] In the process of adding models to the window, traditional computer-side modeling systems often add or create 3D models by dragging and dropping to the window. These operations are all realized by controlling the mouse, and the accuracy and controllability of the mouse operation are strong . At the same time, when using the mouse to perform affine transformation on the object, such as moving and rotating, you can directly place the mouse on the surface of the model for operation. Because of the accuracy and compactness of the mouse, this operation method will not affect the movement. accuracy. But along with the development of equipment, more and more equipment adopt touch screen. The operation of the touch screen device is to replace the mouse with the finger, but when th...
