detailed description

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

In the embodiment of the present invention, an instruction to open the information selection switch is received, the information selection switch is turned on, the movement trajectory of the user's finger is detected, and the information in the first closed area corresponding to the movement trajectory of the user's finger is selected.

In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate.

Embodiment one:

Figure 1 shows a flow chart of an information selection method provided by the first embodiment of the present invention, which is described in detail as follows:

Step S11, receiving an instruction to turn on the information selection switch, and turning on the information selection switch.

Specifically, the instruction to open the information selection switch can be issued in any of the following ways: the user sends out by touching or pressing a designated button, or the smart terminal detects the user's designated action, such as detecting that the user's blinking times are within the preset time limit. When the set switch opens the range, the smart terminal receives the command to open the information selection switch by default.

Step S12, detecting the movement track of the user's finger.

Specifically, the movement trajectory of the user's finger refers to the movement trajectory composed of various positions of the user's finger during one movement. In order for the user to know the moving track of the user's finger detected by the smart terminal, the detected moving track of the user's finger is displayed, for example, the detected moving track of the user's finger is displayed in a curve.

In this step, the movement trajectory of the user's finger includes the movement trajectory formed by the user's finger directly touching the screen of the smart terminal, and also includes the movement trajectory formed by not directly touching the screen of the smart terminal. At this time, the step S12 specifically includes:

A1. Detect whether the user's finger is on the screen. Specifically, whether the current user's finger is on the screen is detected by a sensor provided on the screen.

A2. When the user's finger is on the screen, detect the movement track corresponding to the user's finger during this movement process. Specifically, record the initial position of the user's finger on the screen when the user's finger is detected for the first time, and continue to record the corresponding positions on the screen when the user's finger moves from the initial position. When the user's finger leaves the screen, the detection is stopped, and the recorded Each position forms a movement track corresponding to the user's finger in this movement process.

A3. When the user's finger is not on the screen, determine the projection of the user's finger on the screen, and detect the movement trajectory corresponding to the projection of the user's finger on the screen during this movement process. Specifically, record the initial position where the projection of the user's finger on the screen is detected for the first time, continue to record the corresponding positions of the projection of the user's finger on the screen when the user's finger moves at the initial position, and when the projection of the user's finger is no longer detected , the detection is stopped, and the recorded projections of the user's finger are projected at various positions on the screen to form the corresponding movement track of the user's finger during this movement process.

In the above-mentioned A1-A3, since the movement trajectory formed by the user's finger in two different ways can be detected, the choices of the user are enriched, and the convenience and flexibility of operation are improved.

Step S13, selecting information in the first closed area corresponding to the movement track of the user's finger.

As shown in FIG. 2 , the information in the curve is the information in the first closed area corresponding to the movement track of the user's finger.

Optionally, since invalid information may be selected during the movement of the user's finger, in order to remove the selected invalid information, after the step S13, include:

B1. Detecting a movement track of the user's finger within the first closed area.

B2. When the moving track of the user's finger in the first closed area forms a second closed area, select the first closed area corresponding to the moving track of the user's finger and not include the second closed area information within.

In the above-mentioned B1 and B2, when the movement trajectory of the user’s finger is detected again in the first closed area, it is judged whether the detected movement trajectory forms the second closed area, and if so, it indicates that the user wishes to be removed from the first closed area. The information in the second closed area, otherwise, when the movement track of the user's finger in the first closed area does not form the second closed area, the information in the first closed area is not discarded.

Optionally, when the user wishes to search for information related to the selected information, after the B2, include:

B21. Identifying information in the first closed area corresponding to the selected movement track of the user's finger and not including the second closed area.

B22. Search for corresponding information according to the recognition result.

B23. Outputting search results.

In the above-mentioned B21-B23, since the search operation is performed after excluding the information in the second closed area, the search speed can be improved.

Optionally, since the user usually only wants to select text information when selecting information, in order to reduce the user's subsequent operations, after the step S13, include:

C1. Determine whether the information in the first closed area includes both text information and picture information.

C2. When the information in the first closed area includes both text information and picture information, delete the picture information included in the first closed area, and delete the picture information included in the first closed area to obtain The information is used as the information in the first closed area corresponding to the final movement track of the user's finger.

Certainly, after step S13, if a copy instruction or a delete instruction is received, the information in the first closed area is copied or the information in the first closed area is deleted.

Optionally, the user may perform a search action in the following manner, before step S12, including:

Get the picture in front of the camera. Specifically, the camera installed on the smart terminal shoots things in front of the camera to obtain corresponding pictures, such as pictures corresponding to a certain title including a book.

At this time, the step S12 is specifically: detecting the moving track of the user's finger in the picture.

After the step S13, including:

Identifying information in the first closed area corresponding to the selected movement track of the user's finger; searching for corresponding information according to the identification result; and outputting the search result.

Through the above steps, the information contained in the acquired pictures can be filtered again, thereby reducing the amount of search information and redundancy, and improving the search speed and search accuracy.

In the first embodiment of the present invention, an instruction to open the information selection switch is received, the information selection switch is turned on, the movement trajectory of the user's finger is detected, and the information in the first closed area corresponding to the movement trajectory of the user's finger is selected. Since the information in the first closed area corresponding to the movement track of the user's finger can be selected, and the shape of the movement track of the user's finger can be changed freely, the selected information is more accurate.

It should be understood that in the embodiment of the present invention, the sequence numbers of the above-mentioned processes do not mean the order of execution, and the execution order of each process should be determined by its function and internal logic, rather than the implementation process of the embodiment of the present invention. constitute any limitation.
