DETAILED DESCRIPTION
The following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of various embodiments of the disclosure as defined by the claims and their equivalents. It includes various specific details to assist in that understanding but these are to be regarded as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the disclosure. In addition, descriptions of well-known functions and constructions may be omitted for clarity and conciseness.
The terms and words used in the following description and claims are not limited to the bibliographical meanings, but, are merely used by the inventor to enable a clear and consistent understanding of the disclosure. Accordingly, it should be apparent to those skilled in the art that the following description of various embodiments of the present disclosure is provided for illustration purpose only and not for the purpose of limiting the disclosure as defined by the appended claims and their equivalents.
It is to be understood that the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a component surface” includes reference to one or more of such surfaces.
By the term “substantially” it is meant that the recited characteristic, parameter, or value need not be achieved exactly, but that deviations or variations, including for example, tolerances, measurement error, measurement accuracy limitations and other factors known to those of skill in the art, may occur in amounts that do not preclude the effect the characteristic was intended to provide.
Various embodiments of the present disclosure will be provided to achieve the above-described technical aspects of the present disclosure. In an implementation, defined entities may have the same names, to which the present disclosure is not limited. Thus, various embodiments of the present disclosure can be implemented with same or ready modifications in a system having a similar technical background.
Through the description, ‘user gesture input’ corresponds to an input that a user creates by making a gesture on a touch screen (e.g., in order to control a terminal). For example, user gesture inputs may include a touch, a touch and hold, a drag, a flick, a hold, and the like.
‘Touch’ corresponds to a gesture of touching a screen with a finger or a touch input unit such as a stylus, a pen, or the like. Specifically, a touch has a preset touch time defined as the difference between a touch-in time when a finger or the touch input unit touches the screen and a touch-out time when the finger or the touch input unit is removed from the screen.
‘Touch and hold’ corresponds to a gesture including a touching of a screen with a finger or the touch input unit and keeping the touch of the screen for a predetermined threshold time or longer. The touch and hold has a time difference equal to or larger than a threshold. For example, if the difference between a touch-in time and a touch-out time is greater than or equal to the threshold, then the gesture is determined to correspond to a touch and hold. To indicate whether a touch input is touch or touch and hold, if the touch input is kept for a threshold time or longer, a visual or acoustic feedback signal may be provided to a user.
‘Drag’ corresponds to a gesture of touching a screen with a finger or the touch input unit and moving the touch to another position of the screen without detaching the finger or the touch input from the screen.
‘Flick’ corresponds to a gesture of fast dragging a finger or the touch input unit across a screen. A drag and a flick may be distinguished from each other depending on whether the user moves a finger or the touch input unit at a threshold speed or faster.
‘Hold’ corresponds to a gesture of keeping a touch of a finger or the touch input unit at a specific point of a screen for a threshold time or longer without detaching the finger or the touch input unit from the screen. The hold gesture lasts at a specific point for a threshold time or longer between a touch-in time and a touch-out time.
FIG. 1 illustrates operations of a terminal and a sound output device according to an embodiment of the present disclosure.
Referring to FIG. 1, a terminal 100 may be a portable terminal. The terminal 100 may locate one or more sound sources around the terminal 100 (or a user) and display a terminal image 10 representing the terminal 100 and sound source images 11 to 17 representing the sound sources at the corresponding positions of the sound sources with respect to the terminal 100.
A sound source refers to a source or its equivalent from which a sound is emitted. For example, sound sources may include a person that speaks, a player that performs music, a speaker that outputs music, a phone that rings, and the like. Besides, any other source that outputs a sound may be a sound source.
The terminal 100 may select the sound source image of a sound source to emit a sound according to a user gesture input from among the sound source images 11 to 17, and may output a sound of the selected sound source. In addition, the terminal 100 may provide the sound of the selected sound source to a sound output device 300 (e.g., a hearing aid, an ear-microphone, a headset, or the like).
The terminal 100 may select at least one volume level for a sound source from among a plurality of preset volume levels according to a user gesture input and output a sound of the sound source at the selected volume level. The terminal 100 may also output the sound of the selected sound source at the selected volume level to the sound output device 300.
The sound output device 300 may be a device that outputs a sound, such as a hearing aid, an ear-microphone, a headset, or the like. Various embodiments of the present disclosure will be described in the context of a hearing aid being used as the sound output device 300, by way of example. The hearing aid 300 may receive sound signals of one or more sound sources through microphones, amplify the sound signals, and output the amplified sound signals audibly to a user through a speaker.
The hearing aid 300 may communicate with the terminal 100 wirelessly or wiredly and may receive a sound of a sound source selected from among one or more sound sources from the terminal 100 and output the received sound. The hearing aid 300 may receive a sound of a sound source with a volume controlled to a volume level selected by the terminal 100 and output the received volume-controlled sound.
FIG. 2 is a block diagram of the terminal according to an embodiment of the present disclosure.
Referring to FIG. 2, the terminal 100 may include a reflected-wave transceiver 103, a sound source-distance calculator 105, a sound source-direction calculator 107, and a controller 110. The terminal 100 may further include a mobile communication module 120, a sub-communication module 130, a multimedia module 140, a camera module 150, a Global Positioning Service (GPS) module 157, an Input/Output (I/O) module 160, a sensor module 170, a memory 175, and a power supply 180. Additionally, the terminal 100 may include at least one touch screen 190 and at least one touch screen controller 195.
The controller 110 may include a Central Processing Unit (CPU) 111, a Read Only Memory (ROM) 112 that stores a control program to control the terminal 100, and a Random Access Memory (RAM) 113 that stores an external input signal or data or that is used as a memory space for an operation of the terminal 100. The CPU 111 may include a various number of cores. For example, the CPU 111 may include a single core, dual cores, triple cores, quadruple cores, or the like. The CPU 111, the ROM 112, and the RAM 113 may be connected to one another through an internal bus. The controller 110 may control the reflected-wave transceiver 103, the sound-source distance calculator 105, the sound-source direction calculator 107, the mobile communication module 120, the sub-communication module 130, the multimedia module 140, the camera module 150, the GPS module 157, the I/O module 160, the sensor module 170, the memory 175, the power supply 180, the touch screen 190, and the touch screen controller 195.
The reflected-wave transceiver 103 may transmit an electromagnetic-wave signal in all directions and receive reflected-wave signals resulting from reflecting the electromagnetic-wave signal from objects under the control of the controller 110. The controller 110 may use the reflected-wave signals received from the reflected-wave transceiver 103 in detecting the objects around the terminal 100.
The sound source-distance calculator 105 receives a voice or sound from sound sources through first to nth microphones 162-1 to 162-n, identifies one or more sound sources, and calculates the distance between the terminal 100 and each of the sound sources. Specifically, the sound source-distance calculator 105 generates a plurality of microphone output signals by combining voices or sounds received from sound sources through at least two microphones among the first to nth microphones 162-1 to 162-n and calculates the distance to each sound source based on the sound attenuation rates of the plurality of microphone output signals with respect to distances.
The sound source-direction calculator 107 receives voices or sounds from sound sources through the first to nth microphones 162-1 to 162-n, identifies one or more sound sources, and calculates the direction of each sound source under the control of the controller 110. Specifically, the sound source-direction calculator 107 calculates the direction of each sound source based on a time delay between voices or sounds received from sound sources through at least two microphones among the first to nth microphones 162-1 to 162-n. Information about the direction of each sound source is provided to the controller 110.
The controller 110 may locate at least one object around the terminal 100 (or the user) using the reflected waves received from the reflected-wave transceiver 103.
The controller 110 may identify at least one sound source by receiving voices or sounds from sound sources through the first to nth microphones 162-1 to 162-n. Then the controller 110 analyses the frequency component of the at least one sound source and compares the analyzed frequency component with a predetermined frequency component, thereby determining the type of the at least one sound source. For example, the controller 110 may determine whether a voice or sound from the at least one source sound is a person's voice, a sound coming from an animal, a phone ring, a sound from a vehicle, or the like.
The controller 110 may also calculate the strength of a sound from each sound source, receive information about the distance from the terminal 100 to each sound source from the sound source-distance calculator 105, and receive information about the direction of each sound source from the sound source-direction calculator 107.
According to various embodiments of the present disclosure, the controller 110 may receive from the hearing aid 300 voices or sounds of sound sources received through a plurality of microphones of the hearing aid 300, instead of the first to nth microphones 162-1 to 162-n. Thereafter, the controller 110 may identify at least one sound source, and calculate the sound strength, direction, and distance to the terminal 100 of each sound source. For example, the hearing aid 300 may include at least two microphones and transmit voices or sounds of sound resources received through the at least two microphones to the terminal 100 by communication.
The controller 110 controls display of a terminal image representing the terminal 100 and sound source images representing sound sources on the touch screen 190 based on the positions of the detected objects, the strengths of sounds from the sound sources, the directions of the sound sources, and the distances between the sound sources and the terminal 100. For example, the controller 110 may display the terminal image and the sound source images representing the detected sound sources on a radarscope screen along with at least one of the distance between the terminal 100 and each sound source, the azimuth angle of each sound source, and the strength of a sound from each sound source.
If a sound source is a person's voice, the controller 110 may detect the position of the person, receive information of the person corresponding to the sound source from an external entity like a communication service provider, and display the sound source along with the information of the person corresponding to the sound source. For example, the controller 110 may display the phone number, name, and/or the like of the person corresponding to the sound source.
The distances and directions of sound sources may be displayed with respect to the terminal 100 on the radarscope screen. The sound source images may take the form of figures, characters, or the like. Depending on the sound strengths and distances of sound sources, sound source images representing the sound sources may be different in color or size.
For example, if a sound source emits a loud sound, a sound source image representing the sound source may be displayed larger or in a deeper color than a sound source image representing a sound source that emits a weak sound. If a sound source is near to the terminal 100, a sound source image representing the sound source may be displayed larger or in a deeper color than a sound source image representing a remote sound source. The shape, size, and color of the sound source image of a sound source may be changed selectively according to the sound strength and distance of the sound source.
Alternatively, the controller 110 may control display of the terminal image and the sound source images on a sound source-position indication screen having a predetermined background, instead of the radarscope screen.
As an example, while a terminal image and at least one sound source image are being displayed on the touch screen 190, the controller 110 monitors reception of a user gesture input made by a finger a touch input unit 168 such as an electronic pen. When the user makes a gesture over the touch screen with a finger or the input unit 168, the controller 110 may detect the resulting user gesture input. In an embodiment of the present disclosure, the user gesture input may be at least one of a touch, a touch and hold, a flick, and a hold. Besides, many other user gesture inputs are available.
The controller 110 may select the sound image of a sound source that will output a sound according to a user gesture input from among one or more sound source images and may control output of a sound from the selected sound source through a speaker 163.
Upon selection of at least one of a plurality of predetermined volume levels for a sound source image in response to a user gesture input, the controller 110 may control the speaker 163 to output a sound of a sound source corresponding to the sound source image at the selected volume level.
According to various embodiments of the present disclosure, the controller 110 may select the sound source image of a sound source that will output a sound from among one or more sound source images according to a user gesture input and may control transmission of a sound of the selected sound source to the hearing aid 300 so that the hearing aid 300 may output the sound of the selected sound source.
Upon selection of at least one of a plurality of predetermined volume levels for a sound source image in response to a user gesture input, the controller 110 may control transmission of a sound of the sound source corresponding to the sound source image with a volume controlled based on the selected volume level to the hearing aid 300 so that the hearing aid 300 may output the volume-controlled sound of the selected sound source.
The mobile communication module 120 connects the terminal 100 to an external device through one or more antennas (not shown) by mobile communication under the control of the controller 110.

The short-range communication module 132 may conduct short-range wireless communication between the terminal 100 and an image forming device (not shown) under the control of the controller 110. The short-range communication may conform to Bluetooth, Infrared Data Association (IrDA), Wireless Fidelity (Wi-Fi) Direct, Near Field Communication (NFC), and the like.
The terminal 100 may communicate with the hearing aid 300 through at least one of the mobile communication module 120 and the sub-communication module 130. In addition, the terminal 100 may transmit a sound of a sound source to the hearing aid 300 through at least one of the mobile communication module 120 and the sub-communication module 130. For example, the terminal 100 may transmit a sound of a user-selected sound source to the hearing aid 300 through at least one of the mobile communication module 120 and the sub-communication module 130. The terminal 100 may also transmit a sound of a sound source with a volume controlled based on a user-selected volume level to the hearing aid 300 through at least one of the mobile communication module 120 and the sub-communication module 130.
The terminal 100 may include at least one of the mobile communication module 120, the WLAN module 131, and the short-range communication module 132 according to the capabilities of the terminal 100. For example, the terminal 100 may include a combination of the mobile communication module 120, the WLAN module 131, and the short-range communication module 132 according to the capabilities of the terminal 100. In the present disclosure, one or more of the mobile communication module 120, the WLAN module 131, and the short-range communication module 132 are collectively referred to as a transceiver, which should not be construed as limiting the scope of the present disclosure.
The multimedia module 140 may include a broadcasting communication module 141, an audio play module 142, or a video play module 143. The broadcasting communication module 141 may receive a broadcast signal (e.g., a TV broadcast signal, a radio broadcast signal, a data broadcast signal, or the like) and additional broadcasting information (e.g., an Electronic Program Guide (EPG), Electronic Service Guide (ESG), or the like) from a broadcasting station through a broadcasting communication antenna (not shown) under the control of the controller 110.

The power supply 180 may supply power to one or more batteries (not shown) mounted in the housing of the terminal 100 under the control of the controller 110. The one or more batteries supply power to the terminal 100. Further, the power supply 180 may supply power received from an external power source (not shown) via the cable connected to the connector 165 to the terminal 100. The power supply 180 may also supply power received wirelessly from the external power source to the terminal 100 by a wireless charging technology.
According to various embodiments of the present disclosure, the terminal 100 may include at least one touch screen to provide User Interfaces (UIs) corresponding to various services (e.g., call, data transmission, broadcasting, photo shot, and sound source-position indication). Each touch screen may transmit an analog signal corresponding to at least one touch on a UI to a touch screen controller corresponding to the touch screen. As many touch screen controllers as touch screens may be provided to receive analog signals from the touch screens. According to various embodiments of the present disclosure, the terminal 100 may include at least one touch screen. For the convenience of description, a case of using a single touch screen will be described.
The touch screen 190 may receive at least one user gesture input through a user's body (e.g., fingers including an index finger) or the touch input unit 168 (e.g., a stylus pen, an electronic pen, or the like). The touch screen 190 includes a pen recognition panel (not shown) to recognize a user gesture input from the stylus pen or the electronic pen. The pen recognition panel may recognize the distance between the pen and the touch screen 190 by a magnetic field. In addition, the touch screen 190 may receive a continuous movement of at least one successive touch as a user gesture input.

FIG. 3 is a flowchart illustrating an operation of displaying at least one sound source around the terminal 100 according to an embodiment of the present disclosure.
Referring to FIG. 3, at operation 310, the terminal 100 may determine the bearings of East, West, South, and North with respect to the position of the terminal 100 by means of the geomagnetic sensor 172. Specifically, the terminal 100 may detect the position of the terminal 100 by means of the GPS module 157 and may determine the bearings of East, West, South, and North with respect to the position of the terminal 100 by means of the geomagnetic sensor 172.
At operation 320, the terminal 100 may detect objects around the terminal 100 using reflected waves and locate the detected objects. For example, the terminal 100 may transmit an electromagnetic-wave signal in all directions through the reflected-wave transceiver 113 and receive reflected-wave signals corresponding to the transmitted electromagnetic-wave signals being reflected from objects. The terminal 100 may detect one or more objects around the position of the terminal 100 and may locate the one or more objects using the received reflected-wave signals.
At operation 330, the terminal 100 may distinguish one or more sound sources from one another by analyzing sounds received through a plurality of microphones. For example, the terminal 100 may distinguish one or more sound sources by analyzing voices or sounds received from the sound sources through the first to nth microphones 162-1 to 162-n. According to various embodiments of the present disclosure, the terminal 100 may receive from the hearing aid 300 voices or sounds that the hearing aid 300 has received from sound sources through a plurality of microphones and may distinguish one or more sound sources from one another. For example, rather than receiving the voices or sounds through the first to nth microphones 162-1 to 162-n, the terminal 100 may receive voices or sounds that the hearing aid 300 has received from sound sources through a plurality of microphones included in the hearing aid 300. Thereafter, the terminal 100 may distinguish among the one or more sound sources from which the voices or sounds originate (or are emitted).
At operation 340, the terminal 100 calculates the sound strength, direction, and distance of each of the distinguished sound sources. For example, the terminal 100 may calculate the sound strength of each sound source by analyzing voices or sounds of the sound sources through the first to nth microphones 162-1 to 162-n. In addition, the controller 110 may calculate the distance between the terminal 100 and each sound source through the sound source-distance calculator 103 and may calculate the direction of each sound source through the sound source-direction calculator 105.
At operation 350, the terminal 100 displays the terminal 100 and one or more sound sources around the terminal 100 based on the positions of the detected objects, the calculated sound strengths, directions, and distances of the sound sources. For example, the terminal 100 may display the relative positions of the one or more sound sources around the terminal 100.
For example, the terminal 100 selects at least one sound source to be displayed on the touch screen 190 from among one or more sound sources around the terminal 100 and determines a position at which the selected sound source is to be displayed on the touch screen 190. Thereafter, the terminal 100 displays the at least one sound source at the determined position of the touch screen 190.
Specifically, the terminal 100 may select at least one sound source within a predetermined distance from the terminal 100 or at least one sound source having a sound strength equal to or larger than a predetermined (or selected) level from among one or more sound sources around the terminal 100, so that the selected at least one sound source may be displayed on the touch screen 190.
The display position of the selected at least one sound source may be determined, taking into account the size of the touch screen 190 and the distance between the terminal 100 and the at least one sound source.
For example, the center point of the touch screen 190 may be set as the position of the terminal 100 and the display position of the at least one sound source may be determined with respect to the center point of the touch screen 190 based on the distance between the terminal 100 and the at least one sound source, taking into account the size of the touch screen 190. For example, the terminal 100 may display the position of the terminal and the relative positions of the at least one sound source based on a scaling according to the size of the touch screen 190.
The terminal 100 may display a terminal image representing the terminal 100 at the position of the terminal 100 on the touch screen 190 and at least one sound source image representing the at least one sound source at the determined position of the at least one sound source on the touch screen 190.
The terminal 100 may display the terminal image and the at least one sound source image on a predetermined type of screen and may additionally display at least one of the distance, an azimuth angle, and a type of the at least one sound source on the screen.
A sound source image may take the form of a figure, a character, or the like to represent a sound source. The sound source image may be displayed in a different color or size according to the sound strength and distance of the sound source. For example, if a sound source emits a loud sound, a sound source image representing the sound source may be displayed larger or in a deeper color than a sound source image representing a sound source that emits a weak sound. As another example, if a sound source is near to the terminal 100, a sound source image representing the sound source may be displayed larger or in a deeper color than a sound source image representing a remote sound source. The shape, size, and color of a sound source image corresponding to a sound source may be changed selectively according to the sound strength and distance of the sound source. A sound source image may be formed into a shape matching the type of a sound source. For example, the sound source image may be formed into a shape representing that the type of the sound source corresponds to a person, a phone, or an instrument, and the like.
If the type of a sound source is a person's voice, the terminal 100 may detect the position of the person, receive information (e.g., the phone number and name) of the person corresponding to the sound source from an external entity like a communication service provider, and display the sound source along with information of the corresponding to the sound source. According to various embodiments of the present disclosure, the terminal 100 may determine that the person from whom the sound is received corresponds to a contact stored in the terminal 100. As a result, the terminal 100 may retrieve and display contact information (e.g., phone number, name, and/or the like) associated with the person.
The terminal 100 and sound sources around the terminal 100 may be displayed in a predetermined indication scheme such as a radarscope display scheme, a sound source-position indication scheme other than the radarscope display scheme, or other unmentioned schemes.
An embodiment of the present disclosure in which the terminal 100 and sound sources around the terminal 100 are displayed in the radarscope display scheme will first be described.
FIG. 4 illustrates a radarscope screen that displays sound sources around a terminal according to an embodiment of the present disclosure.
Referring to FIG. 4, the distances and directions of sound sources may be displayed with respect to the terminal 100 on a radarscope screen. The bearings of North, West, South, and East are marked with N, W, S and E on the radarscope screen. A terminal image 40 representing the terminal 100 and one or more sound source images 41 to 44 respectively representing sound sources may be displayed on the radarscope screen. The radarscope screen may further display the distance between the terminal 100 and each sound source, and the sound strength 47 and azimuth angle 49 of the sound source. For example, if a source image of source images 41 to 44 is selected, the terminal 100 may display detailed information about the sound source and/or the corresponding sound. For example, the terminal 100 may display the distance between the terminal and the selected sound source, the sound strength of the sound from the selected sound source, contact information or other information relating to characteristics of the selected sound source, and the like.
FIG. 5 illustrates a screen that displays the positions of sound sources around a terminal according to an embodiment of the present disclosure.
Referring to FIG. 5, a sound source-position indication screen may display a terminal image 50 representing the terminal 100 and one or more sound source images 51 to 55 representing sound sources. If a sound source outputs a loud sound, the sound source image of the sound source may be displayed in a deeper color than the sound source image of a sound source that outputs a weak sound. The sound source image of a sound source may indicate whether the type of the sound source is a person's voice (Bla Bla) or a phone ring. According to various embodiments of the present disclosure, the sound source image of the sound source may indicate other types (e.g., common types) of sound sources.
With sound sources around the terminal 100 displayed on a screen in the above manner, the terminal 100 may select a sound source according to a user gesture input, output a sound of the selected sound source, and control the volume of the output sound.
FIG. 6 is a flowchart illustrating an operation of outputting sounds of sound sources in a terminal according to an embodiment of the present disclosure. FIGS. 7A and 7B illustrate screens of a terminal that display sound sources around the terminal according to an embodiment of the present disclosure.
Referring to FIGS. 6, 7A and 7B, at operation 610, the terminal 100 may determine whether a user has touched a sound source image on a screen that displays a terminal image 70 and sound source images 71 to 75 representing sound sources around the terminal 100. The user may touch a sound source image on the screen with a finger or the input unit 168 such as a touch pen or a stylus pen.
If the terminal 100 determines that the user has not touched a sound source image on the screen at operation 610, then the terminal 100 may continue to poll for a user touch on a sound source image (e.g., until the terminal 100 is interrupted to perform another corresponding function based on user input or other operations).
In contrast, if the terminal 100 determines that the user has touched a sound source image on the screen at operation 610, then upon detecting of a touch on a sound source image, the terminal proceeds to operation 620 at which the terminal 100 may output a sound of a sound source corresponding to the touched sound source image. For example, when the sound source image 71 corresponding Bla Bla 3 is touched as illustrated in FIG. 7A, the terminal 100 may output a sound of a sound source corresponding to the touched sound source image 71.
According to various embodiments of the present disclosure, the terminal 100 may transmit a sound of the sound source corresponding to the touched sound source image to the hearing aid 300. For example, the terminal 100 may transmit the sound of the sound source corresponding to the touched (e.g., selected) sound source image to the hearing aid 300 so that the hearing aid 300 may output the sound of the sound source.
When the sound source image 71 corresponding Bla Bla 3 is touched as illustrated in FIG. 7A, the touched sound source image 71 may be displayed in a different manner from the other sound source images 72 to 75 to indicate the touched sound source image 71 as illustrated in FIG. 7B. For example, the touched sound source image 71 may be displayed so as to have a solid outline, and the other sound source images 72 to 75 may be displayed so as to have a dotted outline. According to various embodiments of the present disclosure, other indicia may be used to identify the touched sound source image (e.g., shading, bolding, and the like).
According to various embodiments of the present disclosure, if a plurality of sound source images are touched, sounds of sound sources corresponding to touched (e.g., selected) the plurality of sound source images may be output and the touched sound source images may be displayed differently from the other sound source images so that the touched sound source images may be identified.
At operation 630, the terminal 100 determines whether the user has selected a volume level. For example, one of an intense level, a standard level, and a mute level may be selected according to a user gesture input. The intense level may be a highest volume level, the standard level may be a medium volume level, and the mute level may be a mute sound. The volume levels may further include a level that increases the volume of a selected sound source above those of the other sound sources or a level that decreases the volume of a selected sound source below those of the other sound sources.
According to various embodiments of the present disclosure, a various number of volume levels may be defined (e.g., besides the three volume levels). According to various embodiments of the present disclosure, the volume level may be set by setting a volume bar between a muted position and a position corresponding to a maximum volume. The volumes of the intense level, the standard level, and the mute level may be set by a user or a developer.
If the terminal 100 determines that the user has selected the intense level, then the terminal 100 may proceed to operation 632 at which the terminal 100 may output the sound of the sound source with a volume corresponding to the intense level.
If the terminal 100 determines that the user has selected the standard level, then the terminal 100 may proceed to operation 634 at which the terminal 100 may output the sound of the sound source with a volume corresponding to the standard level.
If the terminal 100 determines that the user has selected the mute level, then the terminal 100 may proceed to operation 636 at which the terminal 100 may mute the sound of the sound source.
According to various embodiments of the present disclosure, the terminal 100 may transmit the sound of the sound source with a volume controlled to a selected volume level to the hearing aid 300 so that the hearing aid 300 may output the volume-controlled sound.
In contrast, if the terminal 100 determines that no volume level has been selected during outputting the sound of the sound source at operation 630, then the terminal 100 proceeds to operation 640 at which the terminal 100 monitors a touch on the sound source image corresponding to the sound source that is outputting sound. For example, at operation 640, the terminal 100 determines whether the user touches the sound source image corresponding to the sound source outputting sound.
If the terminal 100 determines that the sound source image corresponding to the sound source outputting sound is touched, then the terminal 100 proceeds to operation 650 at which the terminal 100 discontinues outputting the sound of the sound source.
If the terminal 100 determines that the sound source image corresponding to the sound source outputting sound is not touched, then the terminal 100 may proceed to operation 630.
According to various embodiments of the present disclosure, if the terminal 100 is outputting the sound of the sound source to the hearing aid 300, the terminal 100 may discontinue outputting the sound of the sound source to the hearing aid 300.
As described above, with sound sources around the terminal 100 displayed on a screen, a user may select a sound source on the screen and the terminal 100 or the hearing aid 300 may output a sound of the selected sound source. In addition, the user may adjust the volume of the sound of the sound source. Therefore, a hearing-impaired person may hear an intended sound source.
While it has been described in the above embodiment of the present disclosure that the terminal 100 selects a sound source from which sound is to be output if a user gesture input is a touch, the terminal 100 may select a user-intended sound source by recognizing many user gesture inputs other than a touch.
FIG. 8 is a flowchart illustrating an operation of selecting a sound source according to a recognized user gesture in a terminal according to an embodiment of the present disclosure.
Referring to FIG. 8, at operation 810, the terminal 100 recognizes (e.g., detects) a user gesture. The user gesture input may be a single gesture input or successive inputs of a plurality of user gestures.
For example, the user gesture input may be a drag input. The user gesture input may be a flick input following a touch and hold input. The user gesture input may be a flick and then hold input after a touch and hold input. The user gesture input may be a hold input at a specific point of the circumference of a circle having a radius defined by a flick input following a touch and hold input. According to various embodiments of the present disclosure, the user gesture may be a voice input.
At operation 820, the terminal 100 determines whether the user gesture input indicates a sound source-selection direction. For example, a user gesture input indicating a sound source-selection direction may be a drag input in an intended sound-output direction after a terminal image is selected.
FIG. 9 illustrates a user gesture input indicating a sound source-selection direction according to an embodiment of the present disclosure.
Referring to FIG. 9, while sound source images 91 to 95 representing one or more sound sources around the terminal 100 are being displayed on a screen, upon receipt of a drag input from a terminal image 90 toward the sound source image 92 corresponding to Bla Bla 3, the terminal 100 determines a sound source-selection direction based on the drag input.
If the terminal 100 determines that the user gesture input indicates a sound source-selection direction at operation 820, then upon the sound source-selection direction being determined, the terminal 100 proceeds to operation 822 at which the terminal 100 selects a sound source in the sound source-selection direction and outputs a sound of the selected sound source.
In contrast, if the terminal 100 determines that the user gesture input does not indicate a sound source-selection direction at operation 820, then the terminal 100 proceeds to operation 830 at which the terminal 100 determines whether the user gesture input indicates a sound source-selection range. For example, a user gesture input indicating a sound source-selection range may be a flick input to a specific range after a touch and hold input to a terminal image.
FIGS. 10A and 10B illustrate a user gesture input indicating a sound source-selection range according to an embodiment of the present disclosure.
Referring to FIGS. 10A and 10B, while a terminal image 1000 and sound source images 1001 to 1005 representing one or more sound sources around the terminal 100 are being displayed on a screen, upon receipt of a touch and hold input to the terminal image 1000 as illustrated in FIG. 10A, and then a flick input corresponding to a specific range (e.g., a 5-m range) as illustrated in FIG. 10B, the terminal 100 determines a sound source-selection range according to the received inputs. The terminal 100 may display a touched and held point according to the touch and hold input and then determine a specific range according to the length of the flick input. According to various embodiments of the present disclosure, the source-selection range may be configured using another input or through a menu selection.
If the terminal 100 determines that the user gesture input indicates a sound-source selection range at operation 830, then the terminal 100 proceeds to operation 832 at which the terminal 100 selects at least one sound source within the indicated range and outputs the sound of the selected at least one sound source.
In contrast, if the terminal 100 determines that the user gesture input does not indicate a sound-source selection range at operation 830, then the terminal 100 proceeds to operation 840 at which the terminal 100 determines whether the user gesture input indicates a sound source-selection distance. For example, a user gesture input indicating a sound source-selection distance may be a flick input and then a hold input after a touch and hold input.
FIGS. 11A to 11C illustrate a user gesture input indicating a sound source-selection distance according to an embodiment of the present disclosure.
Referring to FIGS. 11A to 11C, while a terminal image 1110 representing the terminal 100 and sound source images 1111 to 1115 representing one or more sound sources around the terminal 100 are being displayed on a screen, upon receipt of a touch and hold input to the terminal image 1110 as illustrated in FIG. 11A and then a flick input corresponding to a specific distance (e.g., 5 m) as illustrated in FIG. 11B, the terminal 100 determines a sound source-selection distance according to the received inputs. As illustrated in FIG. 11C, the terminal 100 displays a radius corresponding to the sound source-selection distance from the terminal 100. Upon receipt of a hold input maintained for a predetermined time on the circumference of a circle having the radius indicating the sound source-selection distance, successively to the flick input as illustrated in FIG. 11C, the terminal 100 determines the radius as the sound source-selection distance.
If the terminal 100 determines that the user gesture input indicates a sound-source distance at operation 840, then once the sound source-selection distance is determined, the terminal 100 proceeds to operation 842 at which the terminal 100 may select a sound source within the sound source-selection distance and output a sound of the selected sound source.
In contrast, if the terminal 100 determines that the user gesture input does not indicate a sound-source distance at operation 840, then the terminal 100 proceeds to operation 850 at which the terminal 100 determines whether the user gesture input indicates a sound source-selection position. For example, a user gesture input indicating a sound source-selection position may be a hold input at a specific point on the circumference of a circle having a radius defined by a flick input following a touch and hold input.
FIGS. 12A to 12D illustrate user gesture inputs indicating a sound source-selection position according to an embodiment of the present disclosure.
Referring to FIGS. 12A to 12D, while a terminal image 1140 representing the terminal 100 and sound source images 1141, 1143, 1145, 1147, and 1147 representing one or more sound sources around the terminal 100 are being displayed on a screen, upon receipt of a touch and hold input to the terminal image 1140 as illustrated in FIG. 12A and then a flick input corresponding to a specific distance (e.g., 5 m) as illustrated in FIG. 12B, the terminal 100 may display a radius corresponding to the sound source-selection distance from the terminal image 1140 as illustrated FIG. 12C. Upon receipt of a hold input maintained for a predetermined time on the circumference of a circle having the radius indicating the distance from the terminal 100, successively to the flick input as illustrated in FIG. 12D, the terminal 100 may determine a position on the circumference of the circle having the radius as a sound source-selection position.
Once the terminal 100 determines the sound source-selection position at operation 850, the terminal 100 proceeds to operation 852 at which the terminal 100 may select a sound source at the sound source-selection position and output a sound of the selected sound source.
According to various embodiments of the present disclosure as described above, the terminal 100 distinguishes adjacent sound sources around the terminal 100 and displays the sound sources separately. The terminal 100 may output a sound of a user-selected sound source or control the volume of the output sound.
The terminal 100 may receive sound signals of adjacent sound sources from the hearing aid 300 and display the sound sources. Upon user selection of a sound source, the terminal 100 may transmit a sound of the selected sound source to the hearing aid 300 so that the hearing aid 300 may output the sound of the selected sound source.
If a user selects a volume level for a sound of a sound source, then the terminal 100 transmits the sound of the sound source with a volume corresponding to the selected volume level to the hearing aid 300 so that the hearing aid 300 may output the volume-controlled sound of the sound source.
A description will be given of the configuration and operation of the hearing aid 300 according to an embodiment of the present disclosure.
FIG. 13 is a block diagram of a hearing aid according to an embodiment of the present disclosure.
Referring to FIG. 13, the hearing aid 300 may include a hearing aid controller 310, a microphone unit 320, a converter 330, an amplifier 340, an output unit 350, a wireless unit 360, a memory 370, and a power supply 380.
The hearing aid controller 310 provides overall control to the hearing aid 300 and controls the operations of the microphone unit 320, the converter 330, the amplifier 340, the output unit 350, the wireless unit 360, the memory 370, and the power supply 380.
The microphone unit 320 may include at least two microphones and may detect and receive adjacent sounds. For example, the at least two microphones may be disposed outside the hearing aid 300, receive analog sound signals from adjacent sound sources, in an ear of a user, and transmit the analog sound signals to the converter 330 under the control of the hearing aid controller 310.
The converter 330 may convert the analog sound signals received from the microphone unit 320 to digital sound signals and may convert amplified digital sound signals to analog sound signals. For example, the converter 330 may convert an analog sound signal received from the microphone unit 320 to a digital sound signal and provide the digital sound signal to the hearing aid controller 310.
The hearing aid controller 310 performs digital signal processes on the digital sound signal received from the converter 330, such as unnecessary noise cancellation, feedback control, amplification gain control, non-linear amplification, and the like. Thereafter, the hearing aid controller 310 provides the processed digital sound signal to the converter 330.
The amplifier 340 amplifies the digital sound signal received from the converter 330 based on an amplification gain received from the hearing air controller 310 and provides the amplified sound signal to the hearing aid controller 310.
The converter 330 converts the processed digital sound signal received from the hearing aid controller 310 to an analog sound signal and provides the analog sound signal to the output unit 350.
The output unit 350 outputs the received analog sound signal.
