DETAILED DESCRIPTION
Hereinafter, various examples will be described in detail with reference to the accompanying drawings. It should be noted that the same elements will be designated by the same reference numerals although they are shown in different drawings. Furthermore, details of known functions and configurations will be omitted when it would obscure the subject matter of the present disclosure.
Referring to the example of FIG. 1, different types of terminals, such as the first terminal and the second terminal shown in diagram 110, may be paired with a sound wave. In the example of FIG. 1, the first terminal may be a mobile device with telecommunication capabilities, and the second terminal may be another type of device including, but not limited to, a wearable device.
Alternatively, diagrams 120 and 130 are examples illustrating the pairing of terminals of the same type. These terminals are also shown being paired with a sound wave. Diagram 140 illustrates an example of using a sound wave to pair a first terminal of a first type with a plurality of other devices of a different type. Diagram 140 also shows a plurality of terminals of the same type being paired with each other using a sound wave.
In one example, different types of terminals may be paired with each other in a one to one pairing, and terminals of the same type may also be paired with each other in a one to one pairing. Furthermore, different types of terminals may be paired with each other in a one to N pairing, or the same type of terminals may be paired with each other in a N to N pairing.
Referring now to the example method of FIG. 2, in operation 201, a first terminal may check whether a predetermined sensor value is detected by sensors. Here, the sensor may be at least one of a gyro-sensor, a GPS module, or a proximity sensor. The process of detecting sensor values by the first terminal will be described in more detail with reference to FIGS. 3 to 5.
In operation 202, the first terminal transmits a sound wave signal through an output device to the second terminal when the predetermined sensor value is detected.
In one example, when a predetermined gesture is detected by the gyro-sensor, the first terminal may transmit the sound wave signal in operation 202. Alternatively, when predetermined positional information is detected by the GPS module, the first terminal may transmit the sound wave signal in operation 202. That is, the first terminal may send the sound wave signal when the first terminal is at a predetermined position. Alternatively, when the second terminal is identified to be within a reference distance by a proximity sensor of the first terminal, the first terminal may transmit the sound wave signal in operation 202.
In another example, the transmitted sound wave signal may include terminal identification information. The terminal identification information may comprise a terminal profile and a terminal identifier associated with the first terminal. The terminal profile may include the first terminal's name, type, or the like, and the terminal identifier may be an unique key value associated with the first terminal. In a further example, the sound wave signal may be an ultrasonic wave signal or a predetermined audio frequency signal.
In operation 203, the second terminal may receive the transmitted sound wave signal. The second terminal may be located within a specific distance from the first terminal such that the sound wave is able to reach the second terminal.
In operation 204, the second terminal may transmit a response signal to the first terminal that corresponds to the sound wave signal. The second terminal may insert the terminal identifier included in the sound wave signal in the response signal and transmit the same.
In operation 205, the first terminal may receive the response signal and determine whether the response signal meets certain conditions. For example, when the terminal identifier included in the sound wave signal is identical to the terminal identifier included in the response signal, the first terminal may deem the response signal to be compliant with the condition.
In operation 206, if the conditions are met, the first terminal and the second terminal may be paired. The pairing process of the first terminal and the second terminal may be a pre-processing stage for information exchange or may be a mutual communication between the first terminal and the second terminal.
Referring now to the example method of FIG. 3, the gyro-sensor of the first terminal may detect a gesture in operation 301. The gyro-sensor may sense gyroscopic inertia, so it can detect a rotational angle value of the gesture through the first terminal. For example, the gyro-sensor of the first terminal may detect whether the first terminal is in a vertical position or a horizontal position. Thus, when the first terminal is detected to be in the vertical position, the first terminal may display images longitudinally on the screen, otherwise when the first terminal is detected to be in the horizontal position, the first terminal may display images horizontally on the screen.
The first terminal may store a predetermined gesture that, when detected, triggers the transmission of the sound wave signal. For example, the gestures that may include, but are not limited to, shaking hands or waving hands for greeting.
In operation 302, the first terminal may verify whether the detected gesture is the predetermined gesture. As a result of the verification, when the predetermined gesture is detected, the first terminal may detect a geographic position of the device using a GPS module in operation 303. The geographic position may be determined in relation to the detected gesture. In operation 304, when the detected geographic position is a predetermined geographic position, the first terminal may transmit the sound wave signal as described in operation 202.
Referring to the other example method in FIG. 4, in operation 401, the first terminal may verify whether the second terminal is located within a reference distance by using a proximity sensor. The proximity sensor may detect objects within a specific distance from the first terminal. When the second terminal is detected to be located within a specific distance in operation 402, the first terminal may detect a gesture by using gyro-sensor in operation 403. In operation 404, when the detected gesture is a predetermined gesture, the first terminal may transmit the sound wave signal as described in operation 202.
Referring to yet another example method in FIG. 5, the first terminal may detect a gesture by using the gyro-sensor in operation 501. In operation 502, the first terminal may determine whether the detected gesture is the predetermined gesture. In operation 503, when the detected gesture is the predetermined gesture, the first terminal may verify whether the second terminal is located within a reference distance by using the proximity sensor. When the first terminal is verified to be located within the reference distance in operation 504, the first terminal may detect a geographic position of the first terminal by using a GPS module in operation 505. When the detected geographic position is a predetermined geographic position in operation 506, the first terminal may transmit the sound wave signal as described in operation 202.
Referring now to another example method shown in FIG. 6, the first terminal and the second terminal may be paired using a sound wave signal in operation 601. In one example, the first terminal may transmit a sound wave signal when the second terminal is located within a reference distance. In a further example, the sound wave signal may enable the second terminal to execute a pairing application. In turn, the pairing application may generate and transmit a response signal to the first terminal that allows the first terminal and the second terminal to be paired. An example of transmitting the response signal will be described in more detail with reference to FIG. 7.
In operation 602, the first terminal and the second terminal may configure a communication method. In configuring the communication method during the pairing, the first terminal may indicate a desired communication method in the sound wave signal, or the second terminal may indicate a desired communication method in the response signal. The communication method may include, but is not limited to, Bluetooth, Near Field Communication (NFC) and Wi-Fi.
In operation 603, the first terminal and the second terminal may communicate with each other through the configured communication method. The communication may be made for exchanging information or providing other services.
Referring now to the example method of FIG. 7, in operation 701, the second terminal may receive the sound wave signal from the first terminal that is located within a reference distance and, in response to detecting the sound wave signal, the second terminal may install a pairing application. In one example, when a predetermined gesture is detected by a gyro-sensor, the first terminal may check whether the second terminal is located within a reference distance. If the second terminal is located within the reference distance, the first terminal may identify a geographical position of the first terminal with a GPS module and, if the identified geographical position of the first terminal is a predetermined geographical position, the first terminal may transmit the sound wave signal.
The sound wave signal may include a terminal profile and a terminal identifier. In addition, the sound wave signal may include an address of a webpage from which the pairing application may be installed. If the second terminal does not have the pairing application installed therein, the second terminal may install the pairing application using the address of the webpage included in the sound wave.
In operation 702, the second terminal may execute the pairing application in response to the sound wave signal. That is, the pairing application may be automatically executed upon receipt of the sound wave signal. In operation 703, the second terminal may transmit a response signal to the first terminal using the pairing application. The response signal may include the terminal identifier that was included in the sound wave signal. In addition, the response signal may indicate the communication method desired by the second terminal.
If the terminal identifier included in the sound wave signal is identical to the terminal identifier included in the response signal, the first terminal may be automatically paired with the second terminal. Alternatively, the first terminal may be selectively paired with the second terminal by the user.
Referring now to the example apparatus of FIG. 8, an example apparatus 800 for executing the techniques disclosed herein may include a signal output unit 810, a signal input unit 820, a pairing unit 830, and a communication unit 840. The apparatus 800 may be the first terminal or the second terminal.
The signal output unit 810 may transmit a sound wave signal. The signal output unit 810 may include a voice output unit 811 or an ultrasonic unit 812. The voice output unit 811 may output a predetermined audio frequency signal for the sound wave signal through an output device such as a speaker. The ultrasonic unit 812 may output an ultrasonic signal as the sound wave signal.
The signal output unit 810 may transmit the sound wave signal that includes terminal identification information associated with the terminal. The terminal identification information may include a terminal profile and a terminal identifier. The terminal profile may include, but is not limited to, the terminal's name, type, or the like, and the terminal identifier may be a unique key value associated with the terminal.
Although not shown in the drawings, apparatus 800 may include at least one of a proximity sensor, a gyro-sensor, or a GPS module. For example, when a terminal is detected to be within a reference distance by the proximity sensor, the signal output unit 810 may detect the gesture using the gyro-sensor, and if the detected gesture is a predetermined gesture, the signal output unit 810 may transmit the sound wave signal. In addition, apparatus 800 may include at least one processor to execute the units therein. Each processor may be any type of processor including, but not limited to, processors from Intel® Corporation. In another example, each processor may be an application specific integrated circuit (“ASIC”).
The signal input unit 820 receives a sound wave signal transmitted by a remote device. The signal input unit 820 may receive the transmitted sound wave signal through an input device such as a microphone. The signal input unit 820 may receive the sound wave signal in real time. The signal output unit 810 may transmit a response signal corresponding to the sound wave signal. If the terminal identification information included in the sound wave signal is identical to the terminal identification information included in the response signal, the pairing unit 830 may pair terminals.
The communication unit 840 communicates with another communication unit through a predetermined communication method between the paired terminals. The communication method may be indicated in the sound wave signal and transmitted by the terminal that transmits the sound wave signal, otherwise the communication method may be indicated in the response signal and transmitted by the terminal that transmits the response signal. The communication method may include, but is not limited to, Bluetooth, short range wireless communication, or wireless communication.
Referring now to the working example of FIG. 9, in operation 910, when initial power is applied, the first terminal may make a request to the second terminal that is to be paired with the first terminal for short range wireless communication. In operation 920, the second terminal may make a tag with respect to a predetermined position according to the request of the first terminal by user of the second terminal. When the second terminal is tagged at the predetermined position by the user, in operation 930, the second terminal may access an installation page for a pairing application that enables the second terminal to be paired with the first terminal using the sound wave signal.
In operation 940, the second terminal may install the pairing application 950 and the first terminal may be paired with the second terminal.
Referring now to the working example of FIG. 10, the first terminal 1010A and the second terminal 1010A′ are paired, and the third terminal 1020B and the fourth terminal 1020B′ are also paired. The second terminal 1010A′ and the fourth terminal 1020B′ may check whether a predetermined gesture is detected by using sensors. The predetermined gesture may include, but is not limited to, shaking hands or waving hands. In this instance, when a predetermined gesture is detected the second terminal 1010A′ or the fourth terminal 1020B′ may transmit a sound wave signal. The gesture may be detected by a gyro-sensor, a GPS module, and/or a proximity sensor.
The second terminal 1010A′ may insert a terminal profile and a terminal identifier associated with the second terminal in the sound wave signal and transmit the same. Alternatively, the fourth terminal 1020B′ may insert a terminal profile and a terminal identifier associated with the fourth terminal in the sound wave signal and transmit the same.
The working example of FIG. 10 assumes that the second terminal 1010A′ transmits the sound wave signal. The fourth terminal 1020B′ may receive the sound wave signal and transmit the response signal corresponding to the sound wave signal. The response signal may include a terminal identifier associated with the second terminal 1010A′. The second terminal 1010A′ may receive the response signal, and if the received response signal includes the terminal identifier transmitted through the sound wave signal, the second terminal 1010A′ may be paired with the fourth terminal 1020B′.
In one example, the sound wave signal or the response signal may indicate the desired communication method. Alternatively, the desired communication method may be configured after pairing, and the second terminal 1010A′ and the fourth terminal 1020B′ may communicate with each other through the configured communication method.
As is apparent from the foregoing, the present invention has an advantage over the conventional method. Typically, a Bluetooth connection must activate Bluetooth functions of both the mobile terminal and scan option to recognize each other. However, according to the teachings of the present invention, a terminal can merely transmit a sound save without activating the Bluetooth functions as required in the past.
