Embodiment 1

[0068] Such as figure 1 As shown, the embodiment of the present application provides a flow chart of a method for determining an operation object, the method is applied to an electronic device, the electronic device has a touch screen, and at least one operation object is displayed on the touch screen, The methods include:

[0069] Step 101, detecting whether there is at least one operation input on the touch screen, and generating detection information;

[0070] Step 102, when the detection information indicates that there is the at least one operation input on the touch screen, forming a sliding track on the touch screen in response to the at least one operation;

[0071] Step 103, judging whether the sliding track satisfies a preset condition; wherein, the preset condition is that the sliding track is a curved track and includes a first position and a second position, wherein the first position and the second The two positions are coincident or non-coincident;

[0072] S...

specific Embodiment approach 1

[0076] Specific implementation mode 1, such as figure 2 , assuming that the first position is figure 2 Point A is the initial position; the second position is figure 2 The middle point B is the end position. Obviously, when point A and point B coincide, the sliding track is a closed curved track. At this time, for step 104, based on the first position and the second position, touch The effective area corresponding to the sliding track is determined on the display screen, specifically:

[0077] Based on the start position and the end position, it is determined on the touch display screen that a closed area formed by the closed curve track is an effective area corresponding to the sliding track. Such as figure 2 The area enclosed by the middle circle is the effective area corresponding to the sliding track.

[0078] For step 105, the determination of the operation object on the sliding track and the operation object in the effective area as the operation object to be pro...

specific Embodiment approach 2

[0080] Specific implementation mode 2, when the sliding trajectory is the non-closed curve trajectory, there are two situations, such as image 3 As shown, it is the first type of non-closed curve trajectory; suppose the first position is image 3 Point A is the initial position; the second position is image 3 Point B is the end position. Obviously, point A and point B do not coincide. For step 104, based on the first position and the second position, on the touch screen, determine the The effective area corresponding to the trajectory, specifically:

[0081] Based on the first tangent line at the starting position (point A), between the second tangent lines at the end position (point B), the intersection point (C) between the first tangent line and the second tangent line point), and the non-closed curve track, and determine the effective area corresponding to the sliding track on the touch display screen. Such as image 3 As shown, the area 40 formed based on the non-cl...

Abstract

The invention discloses a method and a device for determining operands, and is characterized in that the method is applied to electronic equipment, wherein the electronic equipment comprises a touch display screen capable of displaying at least one operand, the method comprises the following steps: detecting whether the touch display screen has at least one operation input and generating a piece of detection information; when the detection information shows that the touch display screen has at least one operation input, responding at least one operation to form a sliding track on the touch display screen; judging whether the sliding track meets predetermined conditions, wherein the predetermined conditions are as follows: the sliding track is a curved track and comprises a first position and a second position, and the first position and the second position are coincident positions or non-coincident positions; when the judging information shows that the sliding track meets the predetermined conditions, determining an effective area corresponding to the sliding track on the touch display screen based on the first position and the second position; and determining an operand on the sliding track and an operand in the effective area as operands to be processed.

Description

technical field [0001] The present invention relates to the field of multi-touch technology, in particular to a method and device for determining an operation object. Background technique [0002] In the prior art, due to the convenience of touch operation and user-friendly operation, electronic devices including touch screens are becoming more and more popular. Existing touch gestures include click, long press, zoom in, zoom out, and swipe. [0003] However, it is not easy to operate on the multi-touch screen for file selection or multiple file selection using the existing touch operation, and it is also easy to operate by mistake, and it is also difficult to cancel the selection. [0004] Existing solution: each file is designed with a check box, and the file is selected by checking the check box. During the invention process, the inventor found that the existing solution has at least the following disadvantages: [0005] If the user needs to make multiple selections, eac...
