Preferred embodiment of the invention

The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments of the present application may be combined with each other arbitrarily.

Example 1

The inventor of the present application finds that the contact on the business card can only be manually added to the mobile terminal after the exchange of the paper business card. Therefore, a scheme is proposed to simulate the exchange of the business card, that is, through the contact between the mobile terminals. The action is triggered to trigger the mobile terminal to automatically add a contact on the business card.

The embodiment provides a method for implementing business card exchange between mobile terminals, including the following operations:

When the mobile terminal receives the operation instruction for exchanging the business card, the mobile device first generates the Bluetooth device name according to the preset manner, and then performs a Bluetooth search. If the device that searches for the Bluetooth device name according to the preset manner is found, the device is determined. Establish a connection to the target device for the target device.

In order to simulate the actual exchange of paper business cards, the specific implementation can be based on the entire action process, rather than based solely on the implementation of a certain state. If you just use the touch as a criterion for adding contacts, there will be some misunderstandings. For example, when two phones are accidentally placed and touched together, it may result in no business cards being exchanged. In the case of intent, the information was accidentally exchanged. Therefore, it cannot be judged by whether or not it is in a certain state, and it should be based on whether or not the parties have an intention to exchange actions. If both parties have an exchange intent, it is possible to automatically add a contact; if one party does not exchange an intent, it does not trigger the automatic addition of the contact.

The necessary and sufficient condition for automatically adding contacts is whether both parties have exchange intentions. This intention is an action process. The most representative of this action process is that the acceleration of the two devices is decremented to 0 and the direction at the same time. Instead, data on the acceleration and direction sensors is required.

Due to the particularity of the sensor, in the process of touching the two terminals, each of them can only obtain their own sensor data, and cannot obtain the data of the other party. Therefore, during the touch process, it is impossible to know whether the other party has an exchange intention. Therefore, after judging that there is an exchange intention, with Bluetooth technology, first specifically mark yourself, then search for devices with similar special annotations, and then establish a transmission communication to confirm whether the other party has an exchange intention at the same time, if there is intention , eventually achieving contact Automatic addition of people.

Therefore, the following considerations have been added:

1) Each judges whether or not it has the intention to exchange business cards;

When the mobile terminal collides, it can be considered as an operation of exchanging business cards, that is, an intention to exchange business cards. Specifically, for the mobile terminal itself, it is determined that the acceleration in a certain direction is rapidly decremented to 0 (ie, the acceleration is decremented to 0 in the set time). It should be noted that the set time is a short time, and the acceleration is reduced to 0 in a short time to be considered as a collision, that is, it is considered that an operation instruction for exchanging business cards is received.

2) If you have an intention, temporarily modify your Bluetooth device name to a special name;

That is to say, the mobile terminal generates the device of the Bluetooth device name according to a preset manner. The mobile terminal can perform DES encryption on the current Bluetooth device name and generate a Bluetooth device name by using the current date and time. The main purpose of temporarily modifying the name of the Bluetooth device is to improve the security of the data transmitted by the device, that is, to identify only the specially named device that meets the requirements for the exchange of the business card, and then perform subsequent data transmission.

3) Then start the Bluetooth search. If you can find a device with a special name around it, then create data that automatically connects and transmits your own intent and business card information.

A specially named device in the vicinity refers to a device that generates a Bluetooth device name in the same preset manner as the mobile terminal. The mobile terminal only needs to decrypt the device name of the surrounding device, and the device name that can perform the decryption operation is the target device, and then the data transmission can be performed.

4) After each gets the data of the other party, it is judged by the algorithm that the other party has the same intention in the same time period, then start to add the contacts respectively.

The algorithm determines whether the other party has the same intent finger in the same time period, and the mobile terminal acquires the acceleration sensor data and the direction sensor data of the target device from the data sent by the target device, and according to the operation instruction of the mobile terminal when receiving the exchange business card The acceleration sensor data and the direction sensor data are judged. If the target device and the acceleration sensor of the mobile terminal are decremented to 0 in the same time period in the same direction, and the directional acceleration of the target device and the mobile terminal is a collision relationship (ie, the target The device and the mobile terminal have opposite acceleration directions, and then the operation information of the target device is determined to be an operation of exchanging business cards, that is, the target device has the same intention as the mobile terminal, and the Exchange business cards.

5) Final restoration of temporary modifications, deletion of temporary sensor data, etc.

It should be noted that the above five aspects may be used separately in a certain scheme, or the above five aspects may be arbitrarily combined and used in some schemes.

The above method will be specifically described below with reference to the accompanying drawings.

As shown in Fig. 1, the coordinate diagram of the acceleration sensor of the mobile phone is described. The values of (X Y Z) we obtain are the acceleration values (possibly negative values) in the three directions of X, Y, and Z, respectively.

The direction sensor is abbreviated as O-sensor, and returns the angle data of the three axes. The unit of the direction data is the angle. The orientation sensor provides three data, azimuth, pitch, and roll. among them,

Azimuth: azimuth, the angle between the magnetic north pole and the y-axis when returning to horizontal, ranging from 0° to 360° (as shown in Figure 2): 0°=North, 90°=East, 180°=South, 270°=West

Pitch: the angle between the x-axis and the horizontal plane, ranging from -180° to 180°

Roll: the angle between the y axis and the horizontal plane, ranging from -90° to 90°

In order to facilitate the demonstration of the collision process between two mobile phones, here is just an example of a collision scene, that is, two mobile phones in the horizontal direction, respectively, along the positive direction of their Y-axis, the scene close to each other, as shown in Figure 3. As shown, the same principle is applied to the scenes that are touched in the X and Z directions.

Throughout the collision process, it can be easily seen that in the same short period of time, the acceleration values of the two in the Y-axis direction may have a difference in magnitude, but will be rapidly decremented to zero. Since the acceleration values we obtained are all sampled according to a certain frequency, it is only necessary to use statistical knowledge to determine whether the two sets of data have a law of rapid decrement to zero in the same period. In addition, it is necessary to determine whether the two devices are close or far away based on the azimuth value of the directional acceleration. Therefore, it is necessary to determine whether or not to exchange business card information according to the acceleration law in the Y direction and the azimuth angle value of the direction sensor.

The following describes the process of exchanging business cards caused by the above-mentioned collision process, and the process is as follows. As shown in Figure 4, the following operations are included:

S10: The two devices are pre-filled with their own virtual business card information;

S11: performing a collision action according to the method of FIG. 3;

S12: each determines whether the acceleration in a certain direction is rapidly decremented to 0. If yes, it indicates that it has an intention to exchange business cards, and executes S20; if not, then jumps to S61;

S20: packaging the acceleration sensor data and the direction sensor data in the collision process together with the virtual business card data thereof, and subsequently as the data information transmitted to the target device;

The reason why the mobile terminal transmits the acceleration sensor data and the direction sensor data to the target device is to facilitate the target device to compare the acceleration sensor data and the direction sensor data with the acceleration sensor data and the direction sensor data of the target device according to the acceleration sensor data and the direction sensor data. Confirm whether the mobile terminal initiates the operation of exchanging business cards. The principle of judging whether to initiate the exchange of business cards is the same as the operation of the S50.

S30: Perform DES (Data Encryption Algorithm) encryption on the name of the Bluetooth device by using the current date and time;

S31: Open Bluetooth to start searching, and at this time, the prompt information of the waiting class is given on the UI;

S32: judging the neighboring Bluetooth devices that are searched, if it is found that the naming of a device can be decrypted by using the DES algorithm, then it is determined to be the target device, and the S40 is continuously executed. If the Bluetooth device encrypted by the DES algorithm is not found, the execution is performed. S61;

S40: Establish an automatic pairing connection with the target device, and send the data packet in the step S20 to the target device;

S41: Check whether there is a data packet received by the target device, and the process skips to S50, and if it is not received, executes S61;

S50: analyzing whether the data meets the condition A, if yes, executing S60, if not, executing S61;

The above condition A represents that the data of the Y direction of the two sets of acceleration sensors is decremented to 0 in the same period of time, and the directional acceleration of the two is the relationship of the collision. Among them, the relationship of decreasing to 0 can be based on the statistically relevant mature algorithm, and the collision relationship of the direction acceleration is relatively simple. It should be noted that the reason for the above condition A is to judge the target device by the condition A. The operation is not the operation of exchanging business cards. If the condition A is met, it can be judged that the operation of the target device is to exchange business cards, and directly enter S60 to add a contact action. If the condition A is not met, it can be judged that the operation of the target device is not to exchange business cards, and may be other operations or misoperations, etc., and the operation of S61 is performed.

S60: According to the received business card information of the other party, each is added as a contact, and a prompt for successfully adding a contact is displayed on the UI;

S61: Turn off Bluetooth, use the DES algorithm to decrypt the name of the Bluetooth device, delete the temporary Sensor data and cache, restore all temporary modifications, and finish the completion.

When the mobile terminal collides, it can be considered as an operation to exchange business cards.
