When a constituent element is included in each mobile device, a function of a corresponding constituent element, which will be described below, may be distributed and thereby executed in each mobile device.
In the present exemplary embodiment, a user A has the first mobile device 100 and a user B has the second mobile device 200. The user A and the user B may have a conversation through the first mobile device 100 and the second mobile device 200. The conversation between the user A and the user B may be a voice conversation and a conversation through a mobile messenger. In the case of the voice conversation, a voice signal is input from each of the first mobile device 100 and the second mobile device 200 to the mobile device control server 300. In the case of the conversation through the mobile messenger, a text is input from each of the first mobile device 100 and the second mobile device 200 to the mobile device control server 300.
The conversation recognition unit 310 recognizes a conversation between the users A and B through the first mobile device 100 and the second mobile device 200. To recognize the voice conversation, the conversation recognition unit 310 may include a general voice recognizer 311. To recognize the conversation through the mobile messenger, the conversation recognition unit 310 may include a general text recognizer 312. As a conversation recognition result of the conversation recognition unit 310, a word and a sentence spoken by each of the users A and B or input through the mobile messenger are extracted for each user.
The user intent verification unit 320 verifies an intent of each of the users A and B based on the recognition result of the conversation recognition unit 310. Depending on necessities, intents of both the users A and B may be verified and an intent of any one user between the users A and B may also be verified. Such user's intent may be verified through interpretation of meaning of the word and the sentence, keyword extraction, and various types of recognition models. The verified user's intent may be, for example, to search for predetermined information, to transfer predetermined information stored in a mobile device to a counter party of a conversation or share the predetermined information with the counter party of the conversation, to determine an appointment place, and to find a destination or guide the destination. When an additional function of the mobile device satisfying the user's intent is automatically executed during the conversation as described above, it is possible to solve inconvenience of stopping the conversation and then performing a required behavior, such as search. It is possible to greatly contribute to improving communication between users.
The additional function control unit 330 executes, in a corresponding mobile device, an additional function corresponding to the user's intent verified with respect to each of the first mobile device 100 of the user A and the second mobile device 200 of the user B. To this end, the mobile device control server 300 transmits a control signal corresponding to the corresponding additional function to each of the first mobile device 100 of the user A and the second mobile device 200 of the user B. A further detailed operation of the additional function control unit 330 will be described below with reference to FIG. 2.
FIG. 2 is a flowchart illustrating a method of controlling a mobile device according to an exemplary embodiment of the present invention.
The conversation recognition unit 310 recognizes a conversation between the users A and B through the first mobile device 100 and the second mobile device 200 (S210).
The user intent verification unit 320 verifies an intent of each of the users A and B based on the recognition result of operation S210 (S220).
When the verified user's intent is to search for predetermined information (S230), the additional function control unit 330 searches for corresponding information through the Internet (S232) and displays the search result through each of the first mobile device 100 and the second mobile device 200 (S234). Here, by enabling each of the first mobile device 100 and the second mobile device 200 to search for the corresponding information, the corresponding search result may be displayed on each of the first mobile device 100 and the second mobile device 200. The mobile device control server 300 may search for the corresponding information and then transmit the search result to each of the first mobile device 100 and the second mobile device 200.
When the search result is obtained, each of the first mobile device 100 and the second mobile device 200 may display the search result by responding to a predetermined behavior of a user. For example, when the user places a mobile device down from a face while making a call, the search result may be displayed at last.
For example, when a conversation between the user A and the user B relates to determining a theater and a time in order to watch the movie “Twilight”, a user's intent is verified to search for screening theaters and a screening timetable of “Twilight”. In this case, the additional function control unit 330 controls the first mobile device 100 and the second mobile device 200 to search for the screening theaters and the screening timetable of “Twilight”, and to display the corresponding search result. Next, the user A and the user B may verify the screening theaters and timetable displayed on their own mobile devices and may determine a theater and a time together while having a conversation.
When the verified user's intent is to transfer, to a counter party of the conversation, predetermined information stored in a mobile device or to share the predetermined information with the counter party of the conversation (S240), the additional function control unit 330 controls the mobile device of the corresponding user to search for the corresponding information (S242) and to display the search result (S244). Depending on necessities, the additional function control unit 330 may transmit the search result to a mobile device of the counter party of the conversation (S246). As described above, the search result may be displayed by responding to the predetermined behavior of the user.
For example, when the conversation between the user A and the user B relates to a case that the user A informs the user B of a contact number of “Hong gildong”, an intent of the user A is verified to transfer the contact number of “Hong gildong” to the user B. In this case, the additional function control unit 330 controls the first mobile device 100 to search for the contact number of “Hong gildong” stored in the first mobile device 100 and to display the contact number of “Hong gildong” when the user places the first mobile device 100 down from a face. Next, the user A may verify the contact number of “Hong gildong” and immediately inform the user B of the verified contact number of “Hong gildong”. The first mobile device 100 may transmit the contact number of “Hong gildong” to the second mobile device 200 using a mobile messenger or a short messaging service (SMS) according to a selection of the user A or automatically.
As another example, when the conversation between the user A and the user B relates to sharing a “weekly work plan” stored in the first mobile device 100 of the user A, an intent of the user A is verified to transfer the “weekly work plan” to the user B and display the transferred “weekly work plan”, and an intent of the user B is verified to receive the “weekly work plan” from the user A and display the received “weekly work plan”. In this case, the additional function control unit 300 controls the first mobile device 100 to search for the stored “weekly work plan” and display the “weekly work plan”, and to transmit the “weekly work plan” to the second mobile device 200′′, and controls the second mobile device 200 to display the “weekly work plan” received from the first mobile device 100. Next, the user A and the user B may have a conversation while viewing the “weekly work plan” together displayed on their own mobile devices.
When the verified user's intent is to determine an appointment place (S250), the additional function control unit 330 searches for a business (for example, a café and a restaurant) of a predetermined region in which the user desires to determine the appointment place (S252) and displays the retrieved business information through a mobile device, for example, the first mobile device 100 and the second mobile device 200, of each user (S254). Here, each of the first mobile device 100 and the second mobile device 200 may display business information together with a map of the predetermined region. In this case, the business information may be displayed by responding to the predetermined behavior of the user.
For example, when the conversation between the user A and the user B includes the content such as “Where do we meet around Gangnam station?”, intents of the user A and the user B are verified to determine an appointment place around Gangnam station. In this case, the additional function control unit 330 controls the first mobile device 100 and the second mobile device 200 to search for a café or a restaurant around Gangnam station and to display the search result together with a map of the surroundings of Gangnam station. Next, the user A and the user B may verify the map and the business information displayed alike on their own mobile devices and may determine the appointment place, while having a conversation.
In the case of the verified user's intent, when an intent of the user A is to find a destination and an intent of the user B is to guide the user A to the corresponding destination (S260), the additional function control unit 330 controls the first mobile device 100 to take a photo of the surroundings with a camera (S262) and to transmit the taken photo to the second mobile device 200 (S264). The additional function control unit 330 controls the second mobile device 200 to display the photo transmitted from the first mobile device 100 (S266).
For example, when the conversation between the user A and the user B includes the content such as “user A: I am near your office. How can I get to your office?”, an intent of the user A is to find and go to an office of the user B and an intent of the user B is to guide the user A to the office of the user B. In this case, the additional function control unit 330 controls the first mobile device 100 to take a photo of the surroundings (in this case, a guiding comment such as “Please set a camera to face towards the front” may be output to the user A), and to transmit the taken photo to the second mobile device 200. The additional function control unit 330 controls the second mobile device 200 to display the photo transmitted from the first mobile device 100. In this case, a guiding comment such as “The photo of surroundings is being transmitted from the user A” may be output to the user B. Accordingly, the user B may view the photo of surroundings transmitted from the user A and accurately guide the user A to the office of the user B while having a conversation with the user A.
