In addition, the braille display 1100 may be divided into a first braille display 1110 and a second braille display 1120 to display Braille characters. More specifically, the control unit 1400 sets at least a part of the braille cells of the braille display 1100 as the reference braille cell 1130, and outputs the braille display to the first braille display 1110 and the second braille display 1120 It is possible to control to divide. Here, the first braille display 1110 may be located on the left side with respect to the reference braille cell 1130, and the second braille display 1120 may be positioned on the right side with respect to the reference braille cell 1130. Accordingly, the first braille display 1110 and the second braille display respectively indicate different contents, for example, the first braille display 1110 displays the contents related to the currently executed program in braille, The controller 1120 can display the contents related to the program that has been executed immediately before the program in braille. The braille indications of the first braille display and the second braille display described above are merely examples, and the present disclosure is not limited thereto.

The user input unit 1200 may receive a user input of the braille terminal 1000 including the braille display. The user input unit 1200 may include a keyboard and the keyboard may be located, for example, in the upper portion of the braille display 1100 of the top board of the braille terminal 1000, but the present disclosure is not limited thereto. The user input unit 1200 may include function buttons located on the side of the braille terminal 1000. The user input unit 1200 may include a plurality of buttons, and the user input may be configured by a combination of the plurality of buttons. The keyboard of the user input unit 1200 may include, for example, eight buttons corresponding to each finger of the user and a center button that the user can operate with the thumb, but the present disclosure is not limited thereto. When the braille terminal 1000 for a visually impaired user is configured with a conventional computer keyboard as a user input unit, the conventional keyboard generally includes more than 100 buttons, which may be difficult for a visually impaired person to use. Accordingly, the braille terminal 1000 of the present disclosure includes a keyboard having a proper number of buttons so that the blind can easily use the braille terminal.

The finger sensing unit 1300 may sense at least one of whether or not the user's one or more fingers touch the braille cell and the movement of one or more fingers.

The finger sensing unit 1300 may include a sensor capable of sensing a user's finger in a contact and / or non-contact manner.

The finger sensing unit 1300 may include a sensor capable of sensing electrostatic capacitance to sense a change in electrostatic capacitance and determine that the user's finger touches the braille cell. The electrostatic capacity of the finger sensing unit 1300 may be changed by the microcurrent flowing through the finger of the user and the finger sensing unit 1300 may determine whether or not the user's finger is positioned on the braille cell You can decide. The finger sensing unit 1300 may be inserted into the module of the braille cell. The module of the braille cell may be constituted by an upper housing having an actuator portion expressing braille and a hole through which the actuator can protrude, an operation means for projecting the actuator, and a lower housing surrounding the actuator. May be located in a gap between the upper housing and the lower housing. The gap may be located in the upper portion of the actuator as shown in Fig. The type and position of the sensor of the above-described finger sensing unit 1300 are merely examples, and the present disclosure is not limited thereto.

The finger sensing unit 1300 may sense a finger of a user located in the braille cell. The finger sensing unit 1300 may include a proximity sensor. The finger sensing unit 1300 may detect the proximity of the user's finger to the braille cell. The finger sensing unit 1300 may be positioned at the lower or upper end of the braille display, for example, or may be overlapped with the braille display 1100 to correspond to each braille cell of the braille display.

For example, when the user is reading a braille cell of the braille display 1100 with a finger, the finger sensing unit 1300 located at the lower end of the braille display 1100 contacts the braille cell of the user's finger , It is possible to detect that the finger is close to the finger sensing unit 1300 without contacting the finger sensing unit 1300. The finger detection unit 1300 may determine that the finger of the user is located in the braille cell of the braille display 1100 when the user's finger senses that the finger of the user is in proximity to the finger detection unit 1300. [ The finger sensing unit 1300 may be configured such that the finger of the user is adjacent to the finger sensing unit 1300 and when the content is displayed on the braille display 1100, It can be determined to be located in the braille cell. For example, when the finger sensing unit 1300 is positioned at the lower end of the braille display 1100 and the user reads the braille display 1100 with the index finger, the index word of the index finger is displayed on the braille display 1100 The finger sensing unit 1300 may sense that the second node of the index finger is approaching. In this case, the finger sensing unit 1300 may determine that the user's finger is positioned on the braille display 1100 based on sensing the index finger.

The finger sensing unit 1300 may include an optical sensor or an ultrasonic sensor having a light emitting unit and a light receiving unit to sense the proximity of the user's finger. The light sensor of the finger sensing unit 1300 may include a light emitting unit and a light receiving unit and may be configured to emit light based on a difference in intensity of light emitted from the light emitting unit and light sensed by the light receiving unit, It can be determined that the finger of the braille cell is located in the braille cell. The closer the user's finger is, the more the light emitted from the light emitting portion can be reflected by the finger and reach the light receiving portion. Accordingly, the optical sensor can detect that the user's finger is in proximity to the optical sensor when the difference between the emitted light and the intensity of the light arriving at the light receiving unit is less than a preset level. In this case, Can be determined to be located in the braille cell.

In addition, the optical sensor of the finger sensing unit 1300 includes a light emitting unit and a light receiving unit, and when the arrival time of the light emitted from the light emitting unit reaches the light receiving unit, It can be determined to be located in the braille cell. The closer the user's finger is, the more light emitted from the light emitting portion can be reflected on the finger and reach the light receiving portion sooner. Accordingly, the optical sensor can detect that the user's finger is in proximity to the ultrasonic sensor when the time for the emitted light to reach the light-receiving unit is less than a predetermined time. In this case, the finger sensing unit 1300 can detect .

In addition, the finger sensing unit 1300 may include an ultrasonic sensor, and may be configured such that when the intensity difference of the ultrasonic waves is equal to or less than a predetermined level, based on the intensity of the emitted ultrasonic waves and the intensity of the returned ultrasonic waves, . The closer the user's finger is, the more reflected ultrasound waves can be reflected on the finger and can be returned. Therefore, the ultrasonic sensor can detect that the user's finger is in proximity to the ultrasonic sensor when the difference between the intensity of the emitted ultrasonic wave and the intensity of the ultrasonic wave that is reached is less than a predetermined level. In this case, Can be determined to be located in the braille cell.

In addition, the finger sensing unit 1300 may include an ultrasonic sensor, and may determine that the user's finger is positioned in the braille cell when the arrival time is less than or equal to a predetermined time based on the time that the emitted ultrasonic waves reach. As the user's finger is closer to the user's finger, the emitted ultrasonic wave is reflected on the finger and can be returned quickly. Therefore, the ultrasonic sensor detects that the user's finger is close to the ultrasonic sensor when the time reached by the emitted ultrasonic wave is less than a predetermined time In this case, the finger sensing unit 1300 may determine that the user's finger is positioned in the braille cell.

The finger sensing unit 1300 may sense a finger of a user located in the braille cell. The finger sensing unit 1300 may include a touch sensor for sensing a touch of a user's finger. The finger sensing unit 1300 may include a sensor for sensing a current, and may sense a change of a current generated by contact with the user's finger to sense that the user's finger touches the braille cell. The finger sensing unit 1300 may sense the touch of the user's finger with the braille cell. The finger sensing unit 1300 may be positioned at the lower or upper end of the braille display, for example, or may be overlapped with the braille display 1100 to correspond to each braille cell of the braille display. At least one of the actuators of the braille cells may be formed of a conductive material so that the finger sensing unit 1300 may detect a change in current generated when the user's finger contacts the braille cell. For example, when the user is reading a braille cell of the braille display 1100 with a finger, the finger sensing unit 1300 located at the lower end of the braille display 1100 contacts the braille cell of the user's finger Can be detected through a change in current. The finger detection unit 1300 may determine that the finger of the user is located in the braille cell of the braille display 1100 when the finger of the user senses that the finger contacts the finger detection unit 1300. [

The finger sensing unit 1300 may include a sensor for sensing a current to sense a change in the current generated by the touch of the user's finger and sense that the user's finger touches the braille cell. At least one of the actuators of each braille cell may be formed of a conductive material so that the finger sensing unit 1300 may detect a change in power generated when the user touches the finger of the user. In addition, a portion other than the actuator, which is a dot of braille in the lower end, the upper end, and the braille of the braille cell so that the current sensing sensor of the finger sensing unit 1300 can detect a change in current due to the contact of the finger, ≪ / RTI >

In addition, the finger sensing unit 1300 includes a piezoelectric element that can sense a pressure of a finger of the user, and the user can sense a pressure of pressing the finger sensing unit. The piezoelectric element may be positioned, for example, in superimposition with the braille display 1100. The finger sensing unit 1300 may sense a pressure that the user presses the finger sensing unit based on the electric power generated by the piezoelectric element. The piezoelectric element may comprise any element that generates an electrical signal in accordance with the rate of change of pressure applied to the element. The piezoelectric element may be made of any material exhibiting a piezoelectric effect.

The finger detection unit 1300 may detect movement of one or more fingers of a user located in the braille cell. The finger sensing unit 1300 may detect that the user's finger repeatedly approaches at least a part of the braille displayed on the braille display 1100 or that the user's finger is performing an operation of rubbing the braille. Further, the finger sensing unit 1300 may sense a pinch-out operation and a pinch-in operation of two or more fingers of the user. In addition, the finger sensing unit 1300 may sense that the two fingers of the user, which include at least a part of the braille displayed on the braille display, are close to each other between two fingers. The finger detection unit 1300 can transmit information on the braille cell in which the user's finger is sensed to the user so that the controller 1400 determines the number of touched user's fingers based on the number of braille cells in which the finger is sensed . For example, when a touch of a user's finger is detected in one to three braille cells in the finger detection unit 1300, the controller 1400 can determine that the user's one finger is touching the braille cell . In addition, when a touch of the user's finger is detected in the five braille cells in the finger detection unit 1300, the controller 1400 can determine that the user's two fingers are touching the braille cell. The relationship between the number of braille cells in which the touch of the user's finger is sensed and the user's finger is only an example, and the present disclosure is not limited thereto.

The finger detection unit 1300 can detect whether the user's one or more fingers touch the braille cell, in which direction the user touches (touch drag operation), how many fingers of the user touch the braille cell, and the like have.

The controller 1400 may control the overall operation of the braille terminal 1000. For example, the controller 1400 may load the content and display it on the braille display 1100, receive the user input to control the braille terminal 1000, or output the content to the braille terminal 1000, Can be controlled.

The control unit 1400 may control the actuator of the braille display 1100 based on a result of sensing the user's finger by the finger sensing unit 1300. The controller 1400 determines whether the user's finger has read all of the braille displayed on the braille display 1100 as a result of sensing the position of the user's finger in the finger detection unit 1300, And to scroll the braille display 1100 based at least in part on the display. If it is determined that one finger of the user has moved from one end of the braille display 1100 to the other end as a result of the detection of the finger detection unit 1300, the control unit 1400 displays the display content of the braille display 1100 So that the next contents can be displayed on the braille display 1100. [

The braille display 1100 includes a limited number of braille cells and can represent a limited number of braille characters. Accordingly, the user must scroll to display the next braille on the braille display 1100 to read the next braille. There is a problem that the user has to press the scroll button and the scroll button for scrolling must be included on both sides or one side of the braille display so that the size can not be reduced. In addition, the visually impaired can develop the tactile sense and feel the material and shape of the protruding portion of the braille, and when the braille is read continuously for a long time, the tactile sense is suffered. When such a blind person presses again the button for scrolling, it may feel uncomfortable due to the tactile sense which is sensitive, and the braille may be misread by the difference in touch of the scroll button and the braille cell. However, in the braille terminal 1000 according to the embodiment of the present disclosure, when the user has read all of the braille displayed on the braille display 1100, the controller 1400 displays the braille display 1100 as the next braille So that the above-described problem can be solved.

In addition, the controller 1400 may control the actuator such that only the braille cells read by the user's finger protrude from the finger sensing unit 1300. The control unit 1400 receives the input of the user from the user input unit 1200 and when it is detected that the user's finger is not located in the braille display 1100 in the finger detection unit 1300, The power of the braille cell of the braille display 1100 may be cut off to reduce the power consumption of the braille terminal 1000. [

In addition, when the finger sensing unit 1300 senses the position of the user's finger, if the finger is sensed in the braille cell of a predetermined range or more (for example, (For example, when a finger is detected by the sensors 4 to 10 and 22 to 28 from the left side of the 32 proximity sensors), it is determined that the palm of the user is located in the braille cell The power of the braille cell of the braille display 1100 can be cut off.

A voltage close to 200V is required to protrude the actuator of the braille cell and the braille display 1100 consumes a lot of power. The Braille terminal may be configured as a mobile terminal including a battery. The use time of the braille terminal 1000 decreases as the movement of the braille display 1100 increases. Therefore, in order to reduce the power consumption of the braille display 1100, the control unit 1400 according to an embodiment of the present disclosure may allow the user to protrude only the braille to be read, or to perform braille reading when the user is inputting the keyboard It is possible to control the power of the Braille display 1100 to be turned off. Therefore, the use time of the braille terminal 1000 according to an embodiment of the present disclosure can dramatically increase.

In addition, the controller 1400 may include a text to speech (TTS) module to output the content displayed on the braille display 1100 as a sound. The control unit 1400 may control the sound output unit 1600 to output the content displayed in the braille display 1100 in the form of sound.

If it is sensed that the user repeatedly reads a specific braille as a result of sensing the position of the user's finger in the finger detection unit 1300 (for example, The user may touch the section three or more times, etc.), and the specific braille character can be output in the form of sound through the TTS module. When the blind person reads the braille display 1100 continuously for a long time, it may be difficult to read the braille by the pain in the hand, and the intricate braille may require a high concentration of the reading to tame the user. In this case, the control unit 1400 can grasp the braille characters that the user is having difficulty in reading based at least in part on the position detection result of the user's finger of the finger detection unit 1300. Accordingly, in this case, the controller 1400 may output the braille characters having difficulty in reading by the user in the form of sounds to facilitate the user's reading of braille characters.

The controller 1400 may control the braille terminal 1000 based on a result of sensing movement of one or more fingers of the user in the finger sensing unit 1300. [

The controller 1400 determines whether or not the user's finger has read all the braille displayed on the braille display 1100 as a result of sensing the position of the user's finger in the finger detection unit 1300, It may decide to inform the user that there are no more characters on the basis. For example, when the user's finger reads all the braille displayed on the braille display 1100 (e.g., when it is detected that the user's finger is located in the last braille cell displayed with braille), the controller 1400 Can control the braille terminal 1000 to notify the user that the reading of the braille displayed by the user is finished by sound, vibration, or the like.

The control unit 1400 determines whether the user's finger repeatedly reads at least a part of the braille displayed on the braille display 1100 as a result of sensing the position of the user's finger in the finger detection unit 1300, Then, based on the determination, the user can decide to output the braille to be repeatedly read out or decide to provide an explanation about the braille the user repeatedly wants to read. For example, when the user repeatedly reads a specific braille or repeatedly touches a specific braille with a finger or rubs a specific braille (e.g., repeatedly touches three times or more), the finger sensing unit 1300 This movement of the user can be detected. The controller 1400 can determine that the user desires to repeatedly read the specific braille when the user's movement is detected by the finger detection unit 1300. [ In this case, the control unit 1400 may output the braille by sound, output the meaning of the braille to the braille display, or provide a search result for the braille.

When the user senses pinch-out operation of two or more fingers of a user in the finger detection unit 1300 when the user performs a user input (e.g., document editing, etc.), the control unit 1400 performs a tap operation or an indent operation Can be performed. For example, when the user performs a pinch-out operation in which one finger is positioned at the start point of the braille display and the other finger is moved away from the one finger, the finger detection unit 1300 detects the finger And the controller 1400 may perform an indent operation or a tap operation on the document being edited.

In addition, the controller 1400 can turn off the power of the braille display 1100 when the finger sensing unit 1300 senses an operation that is a pinch approaching the distance between the two fingers of the user.

When the controller 1400 detects that the user's two fingers are close to the braille display 1100, the controller 1400 controls the controller 1400 to display the braille included between the two fingers , Or can provide an explanation on the Braille characters.

In addition, when the user performs a user input (e.g., document editing, etc.) and the two fingers of the user are close to the braille display 1100, the control unit 1400 detects that the finger is in the finger detection unit 1300 , The braille contained between the two fingers can be blocked or copied. Accordingly, the user can intuitively block or copy the braille displayed on the braille display 1100 while editing the document and utilize the braille to edit the document.

The control unit 1400 may determine to open the menu based on the number of fingers of the user when a plurality of fingers of the user are gathered and an operation of touching the multiple-braille display 1100 is detected by the finger detecting unit 1300 have.

When the finger sensing unit 1300 detects that the user's two fingers 2002 are gathered and touches the braille display 1100 a plurality of times (for example, twice), the controller 1400 displays the menu So that the menu of the braille terminal can be displayed on the braille display 1100.

The control unit 1400 controls the operation of the braille display 1100 when the user's three fingers 2003 are gathered and the operation of touching the braille display 1100 a plurality of times (for example, twice) It may decide to open a menu corresponding to the context (e.g., the menu of the application currently being used).

[ ) So as to display Braille characters, respectively. More specifically, when the control unit 1400 receives a user's input for dividing the braille display from at least one of the user input unit 1200 and the braille display 1100, Cell 1130 as shown in FIG. The braille display 1100 may be divided into a first braille display 1110 and a second braille display 1120 based on the reference braille cell 1130. [ Herein, the reference braille cell 1130 may be a predetermined braille cell set in advance, and may be a braille cell in which predetermined dots are protruded so that the user can distinguish the first braille display and the second braille display. The number of divisible braille displays described above is not limited, and therefore, the control unit 1400 may divide the braille display 1100 into three or more portions.

For example, the control unit 1400 can set the 16th and 17th braille cells corresponding to the cursor buttons as the reference braille cell 1130 based on the user's input to the function button 1220 and the cursor button 1140 have. That is, the reference braille cell 1130 may apply a voltage to the actuator to project an actuator of a predetermined dot, wherein the predetermined dot may be the entire dot including the 16th and 17th braille cells, that is, 16 dots . Therefore, the controller 1400 controls the first braille display 1110 including 15 braille cells on the left side of the 16th braille cell and the 15 braille cells 1110 on the right side of the 17th braille cell, And a second braille display 1120 including the second braille display 1120.

FIG. 3 is an exemplary view showing that a braille terminal according to an embodiment of the present disclosure senses and operates a user's finger.

The braille terminal 1000 may detect that the user's finger 2000 is located in the braille cell of the braille display 1100 by including the finger detection unit 1300. [ The finger sensing unit 1300 of the braille terminal 1000 senses that the user places the finger 2000 in the braille cell to read the braille cell as the finger 2000 approaches the finger sensing unit 1300 . For example, when the finger sensing unit 1300 is positioned at the lower end of the braille display 1100 and the user reads the braille display 1100 with the index finger, the index word of the index finger is displayed on the braille display 1100 The finger sensing unit 1300 may sense that the second node of the index finger is approaching. In this case, the finger sensing unit 1300 may determine that the user's finger 2000 is positioned on the braille display 1100 based on sensing that the second node of the index finger is approaching.

The control unit 1400 may control the actuator of the braille display 1100 based on a result of sensing the finger 2000 of the user by the finger sensing unit 1300. The controller 1400 determines whether or not the user's finger 2000 has read all of the braille displayed on the braille display 1100 as a result of sensing the position of the user's finger 2000 in the finger detection unit 1300 And may decide to scroll the braille display 1100 based at least in part on the determination.

The braille display 1100 includes a limited number of braille cells and can represent a limited number of braille characters. Accordingly, the user must scroll to display the next braille on the braille display 1100 to read the next braille. There is a problem that the user has to press the scroll button and the scroll button for scrolling must be included on both sides or one side of the braille display so that the size can not be reduced. In addition, the visually impaired can develop the tactile sense and feel the material and shape of the protruding portion of the braille, and when the braille is read continuously for a long time, the tactile sense is suffered. When such a blind person presses again the button for scrolling, it may feel uncomfortable due to the tactile sense which is sensitive, and the braille may be misread by the difference in touch of the scroll button and the braille cell. However, in the braille terminal 1000 according to the embodiment of the present disclosure, when the user has read all of the braille displayed on the braille display 1100, the controller 1400 displays the braille display 1100 as the next braille So that the above-described problem can be solved.

In addition, the controller 1400 can control the actuator to protrude only the braille cells read by the user's finger 2000 as a result of sensing the position of the user's finger 2000 in the finger sensing unit 1300. The control unit 1400 receives the user's input from the user input unit 1200 and detects that the finger 2000 of the user is not located in the braille display 1100 in the finger detection unit 1300 The power of the braille cell of the braille display 1100 may be cut off to reduce the power consumption of the braille terminal 1000. [

A voltage close to 200V is required to protrude the actuator of the braille cell and the braille display 1100 consumes a lot of power. The Braille terminal may be configured as a mobile terminal including a battery. The use time of the braille terminal 1000 decreases as the movement of the braille display 1100 increases. Therefore, in order to reduce the power consumption of the braille display 1100, the control unit 1400 according to an embodiment of the present disclosure may allow the user to protrude only the braille to be read, or to perform braille reading when the user is inputting the keyboard It is possible to control the power of the Braille display 1100 to be turned off. Therefore, the use time of the braille terminal 1000 according to an embodiment of the present disclosure can dramatically increase.

If it is detected that the user repeatedly reads the specific braille as a result of detecting the position of the user's finger in the finger detection unit 1300, the control unit 1400 outputs the specific braille in the form of a sound through the TTS module . For example, when the finger sensing unit 1300 senses that the user desires to read a specific braille cell two to three times repeatedly, the control unit 1400 outputs the content of the braille to the user.

In addition, the controller 1400 may receive and process a gesture input according to the position of the user's finger as a result of detecting the position of the user's finger 2000 in the finger sense unit 1300. For example, when the user reads the braille cell using both hands, if one finger is positioned in the braille cell corresponding to the beginning of the content to be audibly heard and the content to be audibly heard is dragged with the other finger, The control unit 1400 can determine to output the corresponding part by voice based on the position of the finger sensed by the finger sensing unit 1300. [
