Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1, an environment diagram of an implementation environment related to an event confirmation method according to various embodiments of the present invention is shown. The implementation environment includes a server 110 and at least two mobile terminals 120.

The server 110 may be a server, a server cluster composed of several servers, or a cloud computing service center.

At least two mobile terminals 120 and the server 110 may be connected through a wireless network or a wired network.

The mobile terminal 120 is an electronic device having a built-in sensor. The electronic device may be a smart phone, a tablet computer, an e-book reader, an MP3(moving picture expert group audio layer iii) player, an MP4(moving picture expert group audio layer iv) player, a laptop computer, or the like. The sensor may be a gyroscope or an acceleration sensor, etc.

For the sake of simplifying the description, the following is only illustrated as the event confirmation method is performed by the server or the smartphone, but it is not limited thereto.

Referring to fig. 2, a flowchart of an event confirmation method according to an embodiment of the present invention is shown. The present embodiment is exemplified by applying the event confirmation method to the server 110 shown in fig. 1. The method comprises the following steps:

step 201, receiving confirmation information sent by at least two mobile terminals respectively; the confirmation information is sent when the mobile terminal receives an event confirmation instruction of a user for a target event, the target event is an event generated by the interaction of at least two users under the online condition, and the confirmation information carries a target event identifier and a geographical position obtained by positioning when the mobile terminal receives an event confirmation operation.

The target event may refer to a buyer or seller conducting an offline transaction, a multi-user conducting an offline activity at a specified location, or a user arriving at a specified location and completing a check-in, etc.

The event confirmation operation refers to an operation that is executed by at least two users together online after the target event is completed, and in general, the event confirmation operations executed by different users are the same. For example, the event confirmation operation may be at least two users pressing a button together or shaking a mobile phone online, and the like.

Optionally, the event confirmation instruction is an instruction generated when the mobile terminal acquires action data of the user through a built-in sensor and the action data is matched with a preset event confirmation operation.

Step 202, obtaining geographic positions carried by at least two pieces of confirmation information with the same target event identifier.

Step 203, detecting whether the acquired at least two geographic positions belong to the same place.

And step 204, when at least two geographic positions belong to the same place, confirming the target event corresponding to the target event identification.

In summary, the event confirmation method provided in this embodiment confirms the target event according to the confirmation information sent by the at least two mobile terminals carrying the geographic locations; the problem that when a certain event needs a plurality of users to perform offline interaction and then online confirmation is performed, the server cannot judge whether the users actually meet and perform interaction is solved; the effect that the server can determine whether the two geographical positions belong to the same place according to the geographical positions carried in the confirmation information sent by the at least two mobile terminals, so that whether the user executing the target event actually meets the scene is determined is achieved.

Referring to fig. 3A, a flowchart of an event confirmation method according to another embodiment of the invention is shown. The present embodiment is exemplified by applying the event confirmation method to the mobile terminal 120 shown in fig. 1. The method comprises the following steps:

step 301, receiving an event confirmation instruction of a user for a target event, where the target event is an event generated by at least two users interacting online.

And step 302, acquiring the current geographic position according to the event confirmation instruction.

Step 303, generating confirmation information carrying the target event identifier and the geographic location, where the target event identifier is used to identify the target event.

Step 304, sending the confirmation information to the server, so that the server obtains the geographical positions carried by at least two pieces of confirmation information with the same target event identifier, and confirming the target event when the at least two geographical positions belong to the same place.

In summary, in the event confirmation method provided in this embodiment, the confirmation information carrying the geographic location is sent to the server through the at least two mobile terminals, and the server confirms the target event according to the confirmation information; the problem that when a certain event needs a plurality of users to perform offline interaction and then online confirmation is performed, the server cannot judge whether the users actually meet and perform interaction is solved; the effect that the server can determine whether the two geographical positions belong to the same place according to the geographical positions carried in the confirmation information sent by the at least two mobile terminals, so that whether the user executing the target event actually meets the scene is determined is achieved.

Optionally, in order to improve the experience of the user performing offline interaction, the event confirmation instruction may be sent after the user completes a preset event confirmation operation, as shown in fig. 3B, step 301 includes:

step 301A, acquiring action data of a user through a built-in sensor;

step 301B, detecting whether the action data matches a preset event confirmation operation;

and step 301C, generating an event confirmation instruction when the action data is matched with the preset event confirmation operation.

Referring to fig. 4A, a flowchart of an event confirmation method according to still another embodiment of the invention is shown. The present embodiment is illustrated by applying the event confirmation method to the implementation environment shown in fig. 1. The method comprises the following steps:

step 401, the mobile terminal collects action data of a user through a built-in sensor.

When a plurality of users finish interaction online and need to use the mobile terminal to confirm online, the mobile terminal can display a confirmation completion interface corresponding to the event, and the confirmation completion interface can be an interface in an application program or a page displayed by a browser.

The confirmation completion interface comprises event confirmation operation prompt information and a confirmation button, wherein the event confirmation operation prompt information is used for indicating a specified action required to be completed when a user presses the confirmation button. When the user presses the confirmation button, the mobile terminal collects the action data of the user during pressing the confirmation button through a built-in sensor.

For example, as shown in fig. 4B, after the user a and the user B have completed the event together, the mobile terminal 41 used by the user a displays a confirmation completion interface 42, and the confirmation completion interface 42 includes an event confirmation operation prompt message 43 and a confirmation button 44. When the user a presses the confirmation button 44 according to the event confirmation operation prompt information 43 and performs a specified action, the mobile terminal 41 collects action data of the user through a built-in sensor. Correspondingly, the mobile terminal used by the user B displays an interface in accordance with the confirmation completion interface 42.

It should be noted that the designated action that the user needs to complete may be to hold the mobile terminal to draw or write in the air while holding the confirmation button, which is not limited in this embodiment.

It should be noted that, the mobile terminal may also collect the motion data of the user through the built-in sensor when displaying the confirmation completion interface, and this embodiment only takes the example that the built-in sensor is triggered to collect the motion data of the user when the user presses the confirmation button, and does not limit the present invention.

Step 402, the mobile terminal detects whether the motion data is matched with a preset event confirmation operation.

The motion data collected by the mobile terminal is typically data collected by a gyroscope and an acceleration sensor, and as one possible implementation, step 402 may include the following steps.

Step 402A, the mobile terminal obtains terminal attitude data acquired by the gyroscope.

As shown in fig. 4C, the mobile terminal rotation includes Z-axis rotation, X-axis rotation, and Y-axis rotation, which refer to rotation around the Z-axis, X-axis, and Y-axis, respectively. The mobile terminal determines the rotation angles corresponding to the three acquired rotations as terminal attitude data according to a built-in gyroscope, and the mobile terminal can determine the current attitude according to the terminal attitude data.

For example, when the rotation angle corresponding to the rotation of the X-axis is 0 ° and the rotation angle corresponding to the rotation of the Y-axis is 0 ° in the terminal posture data acquired by the gyroscope, it indicates that the mobile terminal is currently in a horizontal state.

And step 402B, the mobile terminal acquires the motion direction and the motion speed acquired by the acceleration sensor.

The mobile terminal can acquire the current motion direction and the current motion speed of the terminal through a built-in acceleration sensor while acquiring the terminal posture data.

When the obtained movement speed is 0, the current terminal can be determined to be in a static state; when the obtained movement speed is not 0, the mobile terminal can calculate the running track of the mobile terminal during the period that the user presses the button according to the movement speed and the movement direction.

Step 402C, the mobile terminal detects whether the motion state indicated by the terminal posture data, the motion direction and the motion speed is matched with a preset event confirmation operation.

The mobile terminal determines the motion state of the mobile terminal during the period that the user presses the button according to the acquired terminal posture data, the motion direction and the motion speed, and detects whether the motion state is matched with a preset event confirmation operation.

For example, when the preset event confirmation operation is "place the mobile phone horizontally and press the button", the mobile terminal detects whether the angle corresponding to the X-axis rotation in the terminal posture data is smaller than a first rotation threshold, and whether the angle corresponding to the Y-axis rotation is smaller than a second rotation threshold and the movement speed is 0.

For another example, when the preset event confirmation operation is "hold the button and hold the mobile phone to draw √" in the air, the mobile terminal calculates a motion trajectory of the mobile terminal according to the terminal posture data, the motion direction, and the motion speed during the time when the user holds the button, and detects whether the motion trajectory is √ ".

It should be noted that, when the confirmation completion interface is an interface in the application program, when the application program detects that the confirmation button is pressed, the application program calls the corresponding program interface to acquire the action data acquired by the sensor, and detects whether the action data is matched with a preset event confirmation operation; when the confirmation completion interface is a page displayed by the browser, the browser calls a 'monitoring device direction event' of HTML5(HyperText markup language5, 5 th edition) when detecting that a confirmation button is pressed, acquires action data collected by a sensor, and detects whether the action data is matched with a preset event confirmation operation.

And step 403, when the action data is matched with the preset event confirmation operation, the mobile terminal generates an event confirmation instruction.

When the action data are matched with the preset event confirmation operation, the mobile terminal can confirm that the user completes the specified action during the button pressing process, and generates a corresponding event confirmation instruction.

And step 404, the mobile terminal acquires the current geographic position according to the event confirmation instruction.

In order to enable the server to determine whether at least two mobile terminals performing offline interaction are in the same location, the mobile terminals acquire a current geographic location, which may be latitude and longitude coordinates, by using a built-in GPS (global positioning system) module.

Step 405, the mobile terminal generates a confirmation message carrying a target event identifier and a geographic location, where the target event identifier is used to identify a target event.

When at least two mobile terminals needing offline interaction create a target event, the corresponding user identifications are sent to a server, and the user identifications can be user names of users when the users use the application program.

The server generates an event identifier according to the received at least two user identifiers, and records a corresponding relationship between the event identifier and the at least two user identifiers, where the corresponding relationship may be schematically shown in table one.

Watch 1

Event identification	Performing user identification
		ACTION1	USER1、USER2
ACTION2	USER3、USER4、USER5
		ACTION3	USER1、USER6

And after the server generates event identifications according to the at least two user identifications, the generated event identifications are sent to the corresponding mobile terminals, and the mobile terminals determine the event identifications as target event identifications and store the target event identifications. And when the mobile terminal generates an event confirmation instruction, generating confirmation information according to the stored target event identifier and the acquired current geographic position.

In order for the server to be able to identify the mobile terminal that sent the confirmation, the mobile terminal also needs to add a corresponding user identity to the confirmation,

optionally, the mobile terminal may further add the sending time for sending the confirmation information to the confirmation information, so that the server may verify the confirmation information according to the sending time later.

Step 406, the mobile terminal sends the confirmation information to the server, so that the server obtains the geographic positions carried by at least two pieces of confirmation information having the same target event identifier, and confirms the target event when the at least two geographic positions belong to the same place.

And at least two mobile terminals for offline interaction send the generated confirmation information to the server.

Step 407, the server receives the confirmation information sent by each of the at least two mobile terminals; the confirmation information is sent when the mobile terminal receives an event confirmation instruction of a user for a target event, the target event is an event generated by the online interaction of at least two users, and the confirmation information carries a target event identifier and a geographical position obtained by positioning when the mobile terminal receives an event confirmation operation.

In order to improve the efficiency of event confirmation, after receiving the confirmation information sent by the mobile terminal, the server centrally stores the confirmation information with the same target event identifier according to the target event identifier carried in the confirmation information.

In step 408, the server obtains user identifiers carried by at least two pieces of confirmation information having the same target event identifier.

And the server detects whether other confirmation information carrying the target event identification is stored or not according to the target event identification carried in the confirmation information. And when other confirmation information carrying the target event identifier is stored, the server acquires the user identifier carried in the confirmation information.

It should be noted that, in consideration of the difference in processing performance of the mobile terminal and the network transmission speed, the server will continuously receive the confirmation information with the same target event identifier, so the server will obtain the user identifier carried by the confirmation information with the same target event identifier at regular time intervals within a predetermined time period.

Step 409, the server searches an execution user identifier set corresponding to the target event identifier in the corresponding relationship between the pre-stored event identifier and the execution user identifier according to the target event identifier.

For each event, when all the mobile terminals executing the event send confirmation information to the server, the server may confirm that the event is completed, so the server needs to search, according to a target event identifier carried in the confirmation information, an execution user identifier set corresponding to the target event identifier in a correspondence relationship between pre-stored event identifiers and execution user identifiers, and detect whether all the mobile terminals indicated by the execution user identifier set send the confirmation information, where the correspondence relationship between the event identifiers and the execution user identifiers may be schematically shown in table one.

In step 410, the server detects whether each obtained user identifier belongs to an executing user identifier set.

The server detects whether each acquired user identifier belongs to an executing user identifier set, and executes step 411 when each acquired user identifier belongs to the executing user identifier set; when there are user identities that do not belong to the set of executing user identities, step 416 is performed.

For example, the server obtains confirmation information a and confirmation information B carrying a target event identifier "ACTION 1", where the USER identifier carried in the confirmation information a is "USER 1", and the USER identifier carried in the confirmation information B is "USER 2". The server finds out that the corresponding execution USER identifier sets are 'USER 1 and USER 2' according to the target event identifier 'ACTION 1', and confirms that the obtained USER identifiers all belong to the execution USER identifier sets.

In step 411, the server obtains the sending time of at least two pieces of confirmation information with the same target event identifier.

In order to further verify whether at least two mobile terminals performing offline interaction perform event confirmation at the same time, the server further needs to acquire respective sending times of at least two pieces of confirmation information having the same target event identifier, where the sending times may be added to the confirmation information when the mobile terminals send the confirmation information, or may be recorded when the server receives the confirmation information, and the present invention is not limited to this.

In step 412, the server detects whether the time difference between the at least two acquired sending times is less than a preset time length.

When the time difference between the obtained at least two sending times is smaller than the preset time, the server determines that the at least two mobile terminals have performed event confirmation at the same time, and step 413 is executed; when the time difference between the at least two obtained sending times is greater than the preset time length, the server determines that the at least two mobile terminals do not perform event confirmation at the same time, and step 416 is executed.

For example, the server obtains the confirmation information a and the confirmation information B carrying the target event identifier "ACTION 1". The sending time of the confirmation information A is 2015, 4, month, 20, 10, min and 10 seconds, the sending time of the confirmation information B is 2015, 4, month, 20, day, 10, min and 11 seconds, the time difference between the sending times of the confirmation information A and the confirmation information B is 1 second, the preset time length is 3 seconds, and the server determines that two mobile terminals sending the confirmation information A and B perform event confirmation at the same time.

In step 413, the server obtains the geographical locations carried by at least two pieces of confirmation information having the same target event identifier.

Further, in order to determine whether the user actually performs the offline interaction, the server further needs to obtain geographic positions carried by at least two pieces of confirmation information of the same target event identifier, and detect whether the at least two geographic positions belong to the same location.

In step 414, the server detects whether the at least two obtained geographic locations belong to the same location.

When the at least two obtained geographic positions belong to the same place, executing step 415; when the at least two obtained geographic locations do not belong to the same place, step 416 is performed.

As a possible implementation, the server may detect whether the distance between every two geographic locations is less than a first preset distance.

For example, when the server receives the confirmation information a and the confirmation information B having the same target event identifier, the server obtains the geographic position a carried in the confirmation information a and the geographic position B carried in the confirmation information B, calculates a distance between the geographic position a and the geographic position B, and detects whether the distance is smaller than a first preset distance.

For another example, when the server receives the confirmation information C, the confirmation information D, and the confirmation information E having the same target event identifier, the server obtains the geographic position C carried in the confirmation information C, the geographic position D carried in the confirmation information D, and the geographic position E carried in the confirmation information E, calculates a first distance between the geographic position C and the geographic position D, a second distance between the geographic position C and the geographic position E, and a third distance between the geographic position D and the geographic position E, and detects whether the first distance, the second distance, and the third distance are all smaller than a first preset distance.

It should be noted that there is no strict sequence between step 411 and step 412 and step 413 and step 414, and this embodiment only uses the step 413 and step 414 to be executed after step 411 and step 412 as an example, and does not limit the present invention.

Step 415, when the obtained user identifiers all belong to the set of executing user identifiers, the time difference between at least two sending times is less than the preset time length, and at least two geographical locations belong to the same place, the server confirms the target event corresponding to the target event identifier.

When the acquired user identifiers belong to the execution user identifier set, the time difference between at least two sending times is smaller than the preset time length, and at least two geographic positions belong to the same place, the server can determine that the user corresponding to the target event completes offline interaction, and confirms the target event.

After the server completes the confirmation of the target event, the server can also send feedback information to the mobile terminal corresponding to the target event to prompt the user to complete the confirmation, wherein the feedback information can be character information, picture information or double-screen interaction information and the like.

For example, as shown in fig. 4D, after confirming the target event, the server sends a confirmation success animation to the mobile terminal 41 and the mobile terminal 45, and correspondingly, the mobile terminal 41 and the mobile terminal 45 display the confirmation success animation.

In step 416, when there is a user identifier that does not belong to the set of executing user identifiers, or the time difference between the obtained at least two sending times is greater than the preset time length, or the obtained at least two geographic locations do not belong to the same location, the server stops confirming the target event.

In summary, in the event confirmation method provided in this embodiment, when the target event is confirmed by at least two mobile terminals, the current geographic location is added to the confirmation information and sent to the server; the problem that when a certain event needs a plurality of users to perform offline interaction and then online confirmation is performed, the server cannot judge whether the users actually meet and perform interaction is solved; the effect that the server can determine whether the two geographical positions belong to the same place according to the geographical positions carried in the confirmation information sent by the at least two mobile terminals, so that whether the user executing the target event actually meets the scene is determined is achieved.

The embodiment also collects action data of the user through the built-in sensor through the mobile terminal, and generates the event confirmation instruction when whether the action data is matched with the preset event confirmation operation, so that the user can generate interaction when confirming the event, and the event confirmation modes of the user are enriched.

In this embodiment, the server further detects whether a time difference between sending times of the at least two mobile terminals for sending the confirmation information is smaller than a preset time length, and confirms the target event when the time difference between the at least two sending times is smaller than the preset time length, thereby further determining whether the user has simultaneously confirmed the event.

When more users need to perform offline interaction, the users can pre-define a target location of offline interaction, and the geographic position of the target location is sent to the server, so that the server stores the corresponding relation between the event identification and the target location.

As another possible implementation manner, step 414 may further include the following steps:

the server detecting whether the acquired at least two geographic positions belong to the same place may include: the server acquires a target location corresponding to the target event; the server detects whether the distance between each geographic position and the target place is smaller than a second preset distance.

The server searches a target place corresponding to the target event identifier in the stored corresponding relation between the event identifier and the target place, and detects whether the distance between each geographic position and the target place is smaller than a second preset distance, wherein the second preset distance can be set by a user.

Referring to fig. 5, a block diagram of an event confirmation apparatus according to an embodiment of the present invention is shown. The event confirmation means may be implemented by software, hardware or a combination of both as all or part of the server 110 in fig. 1. The event confirmation apparatus includes:
