The information stored in the storage unit 150 and a method for utilizing the information are described in greater detail below with reference to FIG. 3A to FIG. 8.
The controller 160 may control an overall operation of each element of the terminal 100. Particularly, the controller 160 may receive an input signal from the input unit 131, and may control the display unit 132 to display the interface screen. In particular, the controller 160 may perform voice recognition for a voice signal input through the audio processing unit 120 to obtain a text. The controller 160 may control the display unit 132 to display the interface screen including the recognized text. Detailed operations of each configuration of the terminal 100 are described in greater detail below with reference to FIG. 3A to FIG. 8.
Referring to FIG. 2, the other user's terminal 200 includes a wireless communication unit 210, an audio processing unit 220, an input unit 231, a display unit 232, a storage unit 250, and a controller 260. As described above, the terminal 100 and the other user's terminal 200 mutually perform communication with each other. The configuration of the terminal 100 is substantially identical to the configuration of the other user's terminal 200. However, the terminal 100 is described based on a function of generating and transmitting indication information, and the other user's terminal 200 is described based on a function of receiving and processing the indication information. As described above, the other user's terminal 200 may perform a part or all of the functions of the terminal 100.
According to an embodiment of the present invention, the wireless communication unit 210 may receive the indication information from the terminal 100 to transmit to the controller 260. In addition, the wireless communication unit 210 may receive additional information from the terminal 100 to transmit to the controller 260.
According to an embodiment of the present invention, the storage unit 250 may store an application program that can be performed according to the indication information received from the terminal 100.
FIGS. 3A and 3B are a flowchart illustrating a call procedure of terminals, according to an embodiment of the present invention. The procedure of FIG. 3B may be executed after the procedure of FIG. 3A. However, according to an alternate embodiment of the present invention, the procedure of FIG. 3B may be omitted.
Referring to FIG. 3A, the terminal 100 and the other user's terminal 200 establish a communication connection with each other, in step 305. The user may operate the terminal 100 so that the wireless communication unit 110 establishes a connection to the other user's terminal 200 for a voice call and/or a video call. On the contrary, the other user may operate the other user's terminal 200 so that the wireless communication unit 210 establishes a connection to the terminal 100 for a voice/video call. The user of each terminal 100 and 200 may speak into a microphone of a phone in a state in which the call connection is maintained.
The controller 160 of the terminal 100 detects a voice signal input through the audio processing unit 120, in step 310. The controller 160 provides a first interface, which includes text (first text) corresponding to the detected voice signal, in step 315. The text corresponding to the detected voice signal may include, for example, a text obtained by performing voice recognition for the corresponding voice signal.
FIGS. 4A to 4D illustrate interfaces of a communication procedure, according to an embodiment of the present invention.
Referring to FIG. 4A, a first interface is shown that includes the first text corresponding to the detected voice signal of step 310. The display unit 132 of the terminal 100 displays an interface 410. The interface 410 includes text 412 of the detected voice. For example, the interface 410 may display a text of 300 bytes of most recently recognized voice data. According to another example, the interface 410 may display the text of all voice data recognized after the call has started, and may provide a scroll bar control when a display area of the display unit 132 is insufficient.
As described below, a corresponding function is set with respect to a word and/or a phrase constituting a text. Information on a word and/or a phrase and a function corresponding to the word and/or the phrase may be stored in the storage unit 150. Table 1 shows an example of a correlation between a word and/or a phrase and a function.

For example, when the phrase “my location” is selected, the terminal 100 may obtain location information of the terminal 100 by using a location sensor, e.g., a Global Positioning System (GPS) module, and may transmit this location information and indication information, which provide an indication to display corresponding location information on a map of the other user's terminal 200. The other user's terminal 200 may provide a screen that displays the location information of the terminal 100 on the map, according to corresponding indication information.
Other functions may be applied in addition to those shown in Table 1. When a phrase/word (text) related to a specific function is detected, the controller 160 may display the corresponding phrase/word in a manner distinguished from other text. For example, since “my location” 414 corresponds to a function “provide to display location sensed by GPS”, it may be displayed in a manner distinguished from other text.
For example, the color of the text “my location” 414 may be set differently from the rest of the text, or the background color of the text “my location” 414 may be set differently from the background color of the rest of the text. Alternatively, a part of a font, a font size, a boldface type, italic letters, underlined, a superscript, and a subscript may be set differently from the rest of the text with respect to the text “my location” 414. A specific text or a specific icon may be displayed around the text “my location” 414 to display that the text “my location” 414 corresponds to a specific function. The text “my location” 414 may flicker to be distinguished from the rest of the text.
As shown in Table 1, when various functions are supported, a different text color or a different icon may be allocated for each function. For example, the text “Gangnam Station” and the text “Seoul Station” may be displayed as a red color, and the text “Notepad” may be displayed as a yellow color. According to an alternate embodiment of the present invention, even if various functions are supported, all text related to a special function as shown in Table 1 may be displayed as a red color.
Instead of the information of Table 1, a natural language processing method may be used. For example, the controller 160 may estimate a close meaning of a corresponding text by performing natural language processing for the recognized text, and may determine a corresponding function according to the estimated meaning. For example, in the sentence “go to X”, the “X” may be estimated as a text that indicates a location, and accordingly, if the “X” is selected, a map search function may be provided.
Text corresponding to a voice signal input through the audio processing unit 120, i.e., a voice spoken by the user of the terminal 100, is displayed. However, the method of displaying text, which is recognized from a voice signal converted from a signal transmitted from the other user's terminal 200, may also be provided. In addition, the voice signal input through the audio processing unit 120 and the voice signal converted from the signal transmitted from the other user's terminal 200 may be displayed in parallel. Hereinafter, for convenience, it is illustrated that only the text recognized by the voice signal input through the audio processing unit 120 is displayed.
Returning to FIG. 3A, the input unit 131 receives a selection of second text among the displayed first text, in step 320. Referring to FIG. 4A, the user may select the text “my location” 414 among the first text 412. A touch input at location where the text “my location” 414 is displayed, or other cursor movement input and a confirmation key input, may be identified as an input for selection. The selection may be performed in a spacing unit and/or in a word unit. For example, in FIG. 4A, the “yeah”, “now”, “arrived” may be the unit of selection. When a part of the text “arrived” and/or a location sufficiently adjacent to the text “arrived” is selected, the “arrived” may be selected. In the case of a phrase that stores a related function like the “my location”, the “my location” may be a selection unit as a whole regardless of the spacing unit or the word unit. According to another embodiment of the present invention, the natural language processing method may be applied to set an appropriate selection unit. For example, if two words having strong semantic relevance are located close together, the two words may be one selection unit.
Referring back to FIG. 3A, when the selection input is detected, the controller 160 displays a second interface through the display unit 132, in step 325. Referring to FIG. 4B, the terminal 100 provides a screen of a second interface 420. The screen of the second interface 420 includes a list 422 of functions corresponding to the selected text “my location” 414. The list 422 may further include special functions related to the current location.
The function list 422 may include one or more basic function items and one or more special function items. The basic function items may be applied to all text. For example, at least some of a web search, a dictionary search, and a text transmission for a corresponding text may be included in the basic function items. The special function items may be applied only to a corresponding text. The special function items for the text related to the location may include a map search function.
Referring to FIG. 4B, the list 422 includes basic function items (an internet search, a dictionary search, a text transmission) and special function items (a GPS coordinates transmission, a camera execution, an album selection). The user may select any one of the items.
Referring again to FIG. 3A, the input 131 receives the selection input of any one item among the list included in the second interface, in step 330. For example, the input unit 131 may receive the selection of an item 424 indicating a display of the location information of the terminal 100 among the list 422 of FIG. 4B.
When receiving the selection input of the item indicating a function, the controller 160 generates indication information corresponding to the pertinent item and transmits the indication information to the other user's terminal 200 through the communication unit 110, in step 335. The indication information may include identification information of a function that the other user's terminal 200 should perform. In addition, the indication information may further include a parameter required to perform a corresponding function. For example, the parameter may include one or more of keyword information for a web search function (a map search/a dictionary search), and location information utilized for displaying a map, or some other similar parameters.
FIG. 3C is a flowchart illustrating an indication information transmission procedure of step 330, according to an embodiment of the present invention.
The input unit 131 of the terminal 100 receives an input for transmitting the indication information, in step 380. For example, the input unit 131 may receive the selection input of any one item of the function list, and this input is an input for transmitting indication information. The controller 160 generates the indication information corresponding to the selected transmitted input and determines whether the indication information is within a range of transmission based on a Short Message Service (SMS) standard, in step 382.
When the indication information is within a length range of the SMS, the controller 160 converts data into a Transaction Protocol Data Unit (TPDU) type. The controller 160 performs a circuit switching so that the communication unit 110 may utilize a circuit network, and transmits an SMS including the indication information of the TPDU type to the other user's terminal 200 through the circuit network, in step 386.
When the indication information is beyond the length range of the SMS, the controller 160 converts the data into a packet type including a header and Multipurpose Internet Mail Extensions (MIME), in step 388. The controller 160 performs a packet switching so that the communication unit 110 may utilize a packet network, and transmits a multimedia message including the indication information of a packet type to the other user's terminal 200 through the packet network, in step 390. Instead of steps 388 and operation 390, an indication information transmission process of a long message type may be utilized.
The indication information may be transmitted according to the procedure of FIG. 3C. However, according to another embodiment of the present invention, the indication information may be transmitted from the terminal 100 to the other user's terminal 200 through communication using another type of signal/packet besides short message/multimedia message/long message.
Referring back to FIG. 3A, the communication unit 210 of the other user's terminal 200 receives the indication information, in step 340, to transmit to the controller 260. The controller 260 of the terminal 200 may perform an application (or other function) corresponding to the indication information received, in step 340.
Referring to FIG. 4C, the controller 260 of the other user's terminal 200 displays an interface 430 asking whether to execute a function according to the received indication information through the display unit 232. When the other user selects a “Yes” button 432, a corresponding function is executed. In the embodiment of FIG. 4A to FIG. 4D, the transmitted indication information may indicate a function of displaying a location of the terminal 100. Thus, in FIG. 4D, the other user's terminal 200 displays a map 440 through the display unit 232, and displays an icon indicating a location 442 of the terminal 100 on the map. The location information of the terminal 100 may be included in the above-described indication information.
FIGS. 5A to 5D illustrate interface screens, according to another embodiment of the present invention.
The interface screens of FIGS. 5A to 5D correspond to the performance of the procedure of FIG. 3A.
Referring to FIG. 5A, a first interface 510 of the terminal 100 is displayed. The first interface includes voice recognized text 512. The user may select a text “ABC” 514. Accordingly, the terminal 100 displays a second interface 520 of FIG. 5B. The second interface 520 includes a function list 522 corresponding to the text “ABC”. A map search execution item 524 is included in the function list 522 corresponding to the text “ABC”. The terminal 100 receives the selection input for the map search execution item 524. Accordingly, the indication information indicating a map search execution may be transmitted from the terminal 100 to the other user's terminal 200. The indication information may include indicators indicating the map search execution and a parameter (text “ABC”) for the relevant function.
When the indication information is transmitted to the other user's terminal 200, as shown in FIG. 5C, the terminal 200 may display an interface 530 asking whether to execute the map search function according to the indication information. When a “Yes” button 532 is selected, a screen 540 of the map search function may be displayed as shown in FIG. 5D. A location 542 of a search result of a search word “ABC” may be displayed within the map 540 through the icon, or the like.
FIGS. 6A to 6D illustrate interface screens, according to another embodiment of the present invention.
The interface screens of FIGS. 6A to 6D correspond to the performance of the procedure of FIG. 3A.
Referring to FIG. 6A, a first interface 610 of the terminal 100 is displayed. The first interface 610 includes voice recognized text 612. The user may select a text “DEF” 614. Accordingly, the terminal 100 displays a second interface 620 of FIG. 6B. The second interface 620 includes a function list 622 corresponding to the text “DEF”. An Internet search execution item 624 is included in the function list 622 corresponding to the text “DEF”. The terminal 100 receives the selection input for the Internet search execution item 624. Accordingly, the indication information indicating an Internet search execution may be transmitted from the terminal 100 to the other user's terminal 200. The indication information may include indicators indicating the Internet search execution and a parameter (text “DEF”) for the relevant function.
When the indication information is transmitted to the terminal 200, as shown in FIG. 6C, the terminal 200 displays an interface 630 asking whether to execute the Internet search function according to the indication information. When a “Yes” button 632 is selected, a screen 640 of the map search function may be displayed, as shown in FIG. 6D.
In the embodiments of FIGS. 4A to 6D, interfaces 430, 530, 630, which ask whether to execute the function, may be omitted. In this embodiment of the present invention, a function corresponding to the indication information may be performed without an input for a corresponding interface.
FIG. 7 is a diagram illustrating a memo function interface, according to an embodiment of the present invention. FIG. 8 is a diagram illustrating a schedule management interface, according to an embodiment of the present invention.
When the memo function or the schedule management interface are performed according to the procedure of FIG. 3A, additional information may be transmitted from the terminal 100 to the other user's terminal 200, and corresponding additional information may serve as an input of a corresponding function.
Returning to FIG. 3B, the terminal 100 receives an additional information selection input, in step 345.
For example, if the terminal 200 is performing a notepad function according to the procedure of FIG. 3A, the user of the terminal 100 may select text to be added as input for the notepad, and transmit this text as additional information to the other user's terminal 200. Alternatively, the user of the terminal 100 may select a function that transmits the text of a voice input, which is recognized after a certain point of time, as the additional information. When the additional information is generated in this manner, the additional information is transmitted, in step 350. The short message/multimedia message generation and transmission method as illustrated in FIG. 3C may be utilized for the transmission of the additional information. The additional information may all be transmitted at a single time or may be transmitted two or more times by dividing the additional information.
In step 355, the terminal 200 processes the transmitted additional information as an input for a function being performed. For example, in a notepad interface 710 of FIG. 7, a text “search corresponding patent in DEF” 712 transmitted as additional information is used as an input for a notepad and inputted. That is, if a certain text is input from the terminal 100 to transmit as additional information, a corresponding text is transmitted to the other user's terminal 200 as additional information, and the other user's terminal 200 may utilize the additional information as an input of a function being performed.
Referring to FIG. 8, a schedule function interface 810 is displayed. “July patent day” 812 is transmitted to the other user's terminal 200 as the additional information, and the terminal 200 utilizes “July patent day” 812 as an input for an item of event name of a schedule function being performed. In particular, when a text related to time and/or date is detected, the terminal 100 converts the text into time information and transmits additional information including the time information. In this case, the terminal 200 utilizes the additional information as an input for a start time 814 or an end time 816 among schedule information.
Each step of the flowcharts and a combination of the flowcharts may be performed by computer program instructions. Since computer program instructions may be mounted in a processor of a universal computer, a special computer or other programmable data processing equipment, instructions performed through a processor of a computer or other programmable data processing equipment generates means for performing functions described in steps of the flowcharts. Since the computer program instructions may be stored in a computer available or computer readable memory capable of orienting a computer or other programmable data processing equipment to implement functions in a specific scheme, instructions stored in the computer available or computer readable memory may produce manufacturing articles involving an instruction means executing functions described in steps of the flowcharts.
