Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The embodiment of the invention aims to provide a method for improving the title search efficiency, so as to solve the problem that in the prior art, when a title is searched, a complicated operation process is required, for example, a system main interface needs to be opened firstly, an icon of an application program for title search is found under the main interface, the icon is clicked and then the icon enters an application program running interface, and the content of the application program which needs to be searched is selected under the interface. To solve this problem, the present invention will be further described with reference to the accompanying drawings.
The first embodiment is as follows:
fig. 1 shows an implementation flow of the method for improving topic search efficiency according to the first embodiment of the present invention, which is detailed as follows:
in step S101, an apparatus start instruction is received, a picture acquired by a camera is displayed according to the start instruction, and a cursor is displayed on the picture.
Specifically, the present invention may preset an opening mode different from a normal starting device, for example, the normal starting is to start the device by triggering a power switch, and correspondingly, the present invention may set an opening mode for directly entering the search mode by means of fingerprint unlocking, face unlocking, and the like. The starting instruction can be used for enabling the equipment to enter the running state of the application program for searching the titles from the standby state.
And when the equipment is in the running state of the application program of title search, displaying the picture acquired by the camera in the display screen of the equipment. In order to avoid that a user can effectively distinguish a camera started by an application program of which the current state is the title search from a common camera in a photographing state, corresponding prompt information can be added in a picture acquired by the camera, and the prompt information can be a prompt of text content or a prompt of an icon corresponding to the application program.
And the picture acquired by the camera also comprises a cursor. The cursor can be used for focus prompting of the title searching process, for example, when the focus is completed, the cursor is aimed at the focused content, and the cursor is switched from the first state to the second state, for example, when the focus is not completed, the cursor is composed of four frames, the four frames are in a flashing state, and after the focus is completed, the four frames stop flashing. Or the invention can analyze the focused content after focusing is finished, and frames the title in the focused content by four frames of the cursor, thereby providing convenience for the user to search the title.
In step S102, a shake instruction of a user is received, and the color of the cursor is switched according to the shake instruction.
Specifically, in the embodiment of the present invention, the shake command may be detected by an acceleration sensor, or may be detected by a sensor such as a gyroscope. The shaking instruction may be a plurality of times of reciprocating motion of the device on the same straight line, or may be set as a motion of the device according to a predetermined trajectory, such as a circular motion, a triangular motion, or the like.
And when the equipment is detected to be in a shaking state, correspondingly controlling the color of the cursor according to the shaking instruction. In order to improve the switching efficiency, the switching speed of the color of the switching cursor can be correspondingly changed according to the acceleration of the shaking motion. For example, when the device is shaken at the first acceleration value a1, the next color is sequentially switched to by one shaking, and when the device is shaken at the second acceleration value a2 and a2 is 2 × a1, the device is shaken at one time and is switched to the second color after the current color. Of course, larger acceleration values may also be used for switching. Through the control of the acceleration value, the convenience of user switching can be improved more efficiently.
In step S103, a corresponding question bank is called according to the color of the cursor, and the content in the picture focused by the camera is searched in the question bank.
In the embodiment of the invention, the corresponding relation between the color of the cursor and the question bank can be preset. For example, a mathematical question bank corresponding to a blue cursor, a language question bank corresponding to a red cursor, a history question bank corresponding to a yellow cursor, etc. may be set. Of course, the question bank can be further divided according to needs. After the searched subjects can be determined by the color of the cursor in a grading mode, the subject subsets under the subjects can be further determined in a shaking mode. Therefore, the searching range is more accurate, and the searching efficiency is higher.
The color of the cursor is changed in a shaking mode, and the search range can be determined according to the preset corresponding relation between the cursor and the question bank. After the search range is determined, a camera of the device can be aligned to a topic to be searched, and the searched content is focused. The device identifies the focused content, searches according to the identified content to obtain a title matched with the picture content, and can display the searched result on a display screen of the device. Of course, the results of the search may also be output in conjunction with other output devices, such as a speaker, etc.
In a preferred embodiment of the present invention, if the content in the screen can be matched in the question bank, the content of the matched question is displayed in a black background. The content of the title is displayed under the background of a black screen, so that the content of the title is more effectively highlighted, a user can conveniently and intensively check the search result, and the interference brought to the user by other messages without the search result is reduced.
When the device receives the opening instruction, the device automatically displays the picture shot by the camera and displays the cursor in the picture, when the shaking instruction of the user is received, the color of the cursor is switched according to the shaking instruction, and after the user is switched to the target color, the picture content focused by the camera is searched in the question bank according to the corresponding relation between the color and the question bank, so that the operation of the user is simple, and the searching can be quickly and effectively carried out in different question banks.
Example two:
fig. 2 shows an implementation flow of the method for improving topic search efficiency according to the second embodiment of the present invention, which is detailed as follows:
in step S201, whether a user exists in a predetermined distance zone in front of the device is detected by the infrared detection module.
Specifically, the predetermined distance interval in the embodiment of the present invention is set according to a distance when the user normally uses the device to perform the search. For example, a predetermined distance interval of 20 cm to 50 cm may be set. The distance interval can be adjusted correspondingly according to the use habit of the user.
By setting the distance interval, the false detection of the user when carrying the device can be avoided. For example, when the user puts the device into a pocket, the infrared detection module may detect that the user is present in front of the device. In this case, it is not necessary to acquire a face image of the user and detect the face image, but only by detecting the distance interval, it is possible to determine that the title search is not currently required.
In step S202, when a user is present in a predetermined distance zone in front of the apparatus, the camera is activated, and face data of the user is acquired.
When detecting that there is the user in the interval of preset distance, steerable equipment opens the camera, carries out image acquisition to equipment the place ahead.
When the camera is started to acquire the face data of the user, the content acquired by the camera is not displayed at the front end, namely, the camera can shoot a picture at the rear end and store the picture so as to facilitate subsequent comparison.
In step S203, the acquired face data is compared with the pre-stored face data, and if the acquired face data is the same as the pre-stored face data, a picture acquired by the camera is displayed according to the opening instruction, and a cursor is displayed on the picture.
And comparing the facial data acquired by the camera with the pre-stored facial data, wherein the compared object can comprise facial features of the face, such as eyes, nose, mouth and the like, when the comparison result is smaller than a preset threshold value, the matching failure is represented, and if the comparison result is larger than the preset threshold value, the matching success is represented.
The pre-stored face data can be face data of the owner, of course, for multi-user equipment, a plurality of face data can be set, and when comparing, a plurality of face data need to be compared in sequence.
In step S204, a shake instruction of the user is received, and the color of the cursor is switched according to the shake instruction.
In step S205, a corresponding question bank is called according to the color of the cursor, and the question bank is searched for the content in the picture focused by the camera.
On the basis of the first embodiment of the invention, the embodiment of the invention further adopts a mode of acquiring facial data by infrared detection and combining the camera for comparison, automatically starts a picture acquired by the camera when a comparison result meets requirements, and displays a cursor in the picture, so that the embodiment of the invention can more intelligently and safely search topics, and further improves the convenience of use.
Example three:
fig. 3 shows an implementation flow provided by the third embodiment of the present invention, which is detailed as follows:
in step S301, an apparatus start instruction is received, a picture acquired by the camera is displayed according to the start instruction, and a cursor is displayed on the picture.
In step S302, the direction in which the circular motion is detected is a clockwise direction or a counterclockwise direction.
In the embodiment of the present invention, the shaking instruction is shaking in a circular motion manner, and the present invention further includes detecting a direction of shaking, that is, detecting whether the direction of shaking is clockwise or counterclockwise.
The shake direction can be detected from a change in the acceleration direction of the shake.
In step S303, when the direction of the circular motion is a clockwise direction, the color of the cursor is switched according to a predetermined first order, and when the direction of the circular motion is a counterclockwise direction, the color of the cursor is switched according to a predetermined second order.
When the user shakes clockwise or anticlockwise, different pointer colors can be obtained, and different question banks can be obtained according to the corresponding relation between the pointer colors and the question banks.
When the user needs to switch the color of the pointer, the user can shake the device in a clockwise or counterclockwise mode according to the relationship between the current color and the target color, so that the color of the cursor is correspondingly switched through the first sequence or the second sequence.
The first sequence or the second sequence can be set by the user according to the needs of the user, and the colors of the cursors can be arranged in sequence, wherein the first sequence is forward switching, and the second sequence is reverse switching.
Of course, an identification strip of the color of the cursor may also be set, the color of the cursor is included on the identification strip, and the current color is pointed by the pointer, so that the user can switch the color of the cursor more conveniently.
In step S304, a corresponding question bank is called according to the color of the cursor, and the content in the picture focused by the camera is searched in the question bank.
The embodiment of the invention specifically limits the shaking mode on the basis of the first embodiment, and can switch the color of the cursor according to different sequences by changing the shaking mode, thereby being beneficial to more efficiently switching to the target color by a user and improving the searching efficiency.
