Detailed ways

Referring to FIG. 1 , it is an application environment diagram of a preferred embodiment of the mobile object point selection and positioning system of the present invention. The mobile object pointing and positioning system 10 runs in the processor 3 of the electronic device 1 , and the electronic device 1 further includes a touch screen 2 . In this embodiment, the electronic device 1 may be a mobile phone, a tablet computer or the like. The touch screen 2 is used for displaying moving objects and receiving coordinate information of a touch position when a user touches the touch screen 2 with a finger.

The moving object refers to an icon indicating the current reading position on the touch screen 2, which is similar to a mouse cursor. In the prior art, the anchor point of the moving object is at the center point of the moving object (see Figure 2A), so when the user clicks on the moving object, the finger can easily block the anchor point of the moving object (see Figure 2A). As shown in FIG. 2B ), the user cannot accurately see the indicated position of the moving object. The anchor point is the position indicated by the moving object. The clicking area is an effective touch area for the user to click on the moving object with a finger, and the moving object can be clicked and moved only when the user's finger touches the clicking area.

For the moving object described in the present invention, the positioning point is outside the range of the click area, which can prevent the user from blocking the positioning point when clicking the moving object. Icons (A) to (E) shown in FIG. 3 are some embodiments of the moving objects described in the present invention. Wherein, the shaded part in each embodiment is the click area, the upper left corner apex of the first embodiment (ie icon A) and the fourth embodiment (ie icon D) is the anchor point of the moving object, the second embodiment (ie icon D) is the anchor point of the moving object, and the second embodiment (ie The vertex in the upper right corner of the icon B) is the anchor point of the moving object, and the center of the "cross" shape pattern of the third embodiment (ie icon C) and the fifth embodiment (ie icon E) is the anchor point of the moving object . It is worth noting that any method that defines the anchor point outside the finger selection area does not limit the shape, color, position, direction, and size of the anchor point and the click area, and all belong to the scope of the moving object described in the present invention, including but not limited to Several examples appear in Figure 3.

For moving objects with different graphics, there will be different positioning point positions. You can preset an offset value relative to the center point of the moving object. The position coordinates of the center point plus the offset value are the position of the positioning point. coordinate. The shape or size of the moving object is different, and the preset offset value is also different. Referring to FIG. 4 , it is a specific schematic diagram of the moving object in the third embodiment in FIG. 3 . The graphical range of the moving object 11 is shown in the outermost dotted line box among the figure, and the shape of the selection area 12 is a circle, but in the present embodiment, the range shown in the small dotted line box outside the selection area 12 is uniform. It is an effective touch area of the clicking area 12 , when the user's finger touches within the range of the small dashed box, the moving object 11 can be clicked and moved. According to the position coordinates (X ₁ , Y ₁ ) of the center point 13 of the moving object and the preset offset value (X ₀ , Y ₀ ), the position coordinates (X ₂ , Y ₂ ) of the anchor point 14 can be calculated , the calculation formula is X ₂ =X ₁ +X ₀ , Y ₂ =Y ₁ +Y ₀ . It can be seen from FIG. 4 that the anchor point 14 of the moving object 11 is separated from the click area 12 , wherein the anchor point 14 is located outside the range of the click area 12 .

Referring to FIG. 5 , it is a functional block diagram of a preferred embodiment of the system for point-and-click positioning of a mobile object according to the present invention.

The mobile object point selection and positioning system 10 includes a detection module 100 , an acquisition module 200 , a calculation module 300 and a setting module 400 .

The detection module 100 is used to detect whether the user touches the touch screen 2 according to the coordinate information of the touch position of the user's finger (or other objects, such as a stylus) on the touch screen 2 received by the touch screen 2. To the range of the selection area of the moving object.

The acquisition module 200 is used to acquire the current position coordinates of the center point of the mobile object on the touch screen 2 when the user touches the range of the click area of the mobile object. In this embodiment, when the touch screen 2 displays the moving object, there will be information about the position of the moving object. Generally, the position coordinates of the moving object are the position coordinates of the center point. The touch screen 2 transmits the position coordinates of the center point to the mobile object point selection and positioning system 10, and the mobile object point selection positioning system 10 can calculate the position coordinates of the corresponding positioning points according to the position coordinates of the center point.

The calculation module 300 is used to calculate new position coordinates according to the current position coordinates of the center point and a preset offset value. For example, as shown in Figure 6, the current position coordinates of the center point are (6.4, 5.3), the preset offset value is (-3.2, 3.2), and the calculated new position coordinates are (3.2, 8.5) .

The setting module 400 is used to set the calculated new position coordinates as the current position coordinates of the anchor point of the mobile object, that is, the position currently indicated by the mobile object is the position of the new position coordinates, and then trigger The detection module 100 continues to detect whether the user touches the selection area of the moving object. When it is detected that the user has not touched the range of the clicking area of the moving object, that is, the user's finger has released the moving object, the positioning process ends.

Referring to FIG. 7 , it is a flowchart of a preferred embodiment of the method for selecting and locating a moving object according to the present invention.

Step S10, the detection module 100 detects whether the user touches the touch screen 2 according to the coordinate information of the touch position of the user's finger (or other objects, such as a stylus) on the touch screen 2 received by the touch screen 2. The range of the selection area that touches the moving object. If the user touches the selected area of the moving object, step S12 is executed. If the user does not touch the range of the selection area of the moving object, the process ends.

Step S12, the acquisition module 200 acquires the current position coordinates of the center point of the moving object on the touch screen 2 .

Step S14, the calculation module 300 calculates new position coordinates according to the current position coordinates of the center point and a preset offset value.

Step S16, the setting module 400 sets the calculated new position coordinates as the current position coordinates of the anchor point of the mobile object, that is, the position currently indicated by the mobile object is the position of the new position coordinates.

As shown in Figures 8A-8B, the anchor point of the moving object is separated from the click area. When the user clicks on the moving object, the finger touches the click area, and the anchor point of the moving object is outside the click area, so the anchor point will not covered by fingers. When moving the moving object, the user can accurately observe the indicated position of the moving object, thereby improving the accuracy of operation.
