Electronic devices equipped with a composite human interface

Abstract

In the past, text input devices and pointing devices were configured as separate devices, which resulted in excessive hand movement by users in a work environment where they frequently switched between inputting text, inputting pointing position information, and inputting pointer execution commands, reducing work efficiency. [Solution] In a composite human interface device, the first composite function input button, which is composed of a control unit and a first composite function input button, comprises a cover unit (1010) that is contacted by a user's finger, an electrode unit (1020) that includes a transmitter and a receiver for forming an electric field, an elastic unit (1050) that moves from a first height to a second height upon receiving a first pressure from the cover unit and restores to the first height when the first pressure on the cover unit is released, and a switch unit that generates an electrical signal indicating the input of a predetermined character.

[0007] The present invention relates to a human interface for allowing a user to input text information or pointing position information into a digital device capable of receiving text or pointing position related information, such as a computer, a laptop, a tablet PC, or a mobile phone, and for transmitting the text information or pointing position information to the digital device.

[0008] 2. Description of the Related Art A keyboard having a plurality of physical buttons connected to an elastic body and a switch is widely used as an existing text information input device.

[0009] In addition, in digital devices equipped with a touch interface, a method is used in which a virtual keyboard is displayed on a display, and when a user touches the virtual keyboard displayed on the display with a part of the user's body, the user's gesture or electrical signal is detected and text is entered on the virtual keyboard displayed on the part touched by the user.

[0010] The touch interface may recognize a user's touch by recognizing the movement of a part of the user's body, by recognizing contact with a particular contact surface, by sensing the flow of electric current through the user's body, or by sensing that light or sound waves are being blocked or interfered with by a part of the user's body.

[0011] Examples of touch interfaces include pressure sensitive touch screens, capacitive touch screens, optical touch screens, and ultrasonic touch screens.

[0012] A resistive touch screen or pressure sensitive touch screen is a touch screen that operates by detecting pressure.

[0013] The advantages of resistive touch screens are that they are inexpensive and can be written on with a stylus pen or in small squares, but they are known to have disadvantages in that since they use pressure, they cannot recognize if you press too hard, and they are somewhat less sensitive to touch than electrostatic touch screens.

[0014] A resistive touchscreen is made up of several layers.

[0015] Among these multiple layers are conductive layers, and two conductive layers are opposed to each other with an air layer between them.

[0016] When you press the outer screen, the two conductive layers come into contact with each other, which changes the resistance and current, thus registering a touch.

[0017] Capacitive sensing, or capacitive touch, is a method of sensing motion using a capacitive coupling effect.

[0018] Unlike vacuum touchscreens, which use pressure, capacitive touchscreens are made from a highly conductive glass called indium tin oxide.

[0019] By attaching sensors to the four corners of the glass, an electric current flows across the surface of the glass.

[0020] This is the electrostatic principle by which changes in current are recognized.

[0021] The moment you touch your finger to the screen, the electrons that were flowing through the glass begin to flow through your finger and into your body, and the sensor detects the location where this change occurs and then begins to function.

[0022] The electrostatic touch method is known to have the advantage of smoother operation and scrolling than pressure-reducing touchscreens, as it recognizes a light touch on the screen rather than the need to apply force to it.

[0023] Furthermore, the electrostatic touch system allows multi-touch, which allows touching multiple points.

[0024] Since the electrostatic touch method is a method that utilizes changes in electric current to operate the device, it may be necessary to use leather gloves, which do not conduct electricity, or it may not be possible to operate it with your fingernails or a stylus pen.

[0025] However, you can touch the screen by using a separate electrostatic stylus pen.

[0026] Because the sensor is sensitive, it may be affected by surrounding devices.

[0027] Optical touchscreens work by using an infrared camera and infrared light attached to the top of the touchscreen to measure the coordinates of the shadow of an object attempting to touch the screen.

[0028] Ultrasonic touch screens work by emitting ultrasonic waves onto the screen, sensing the interference effect caused by a user's touch, and measuring the coordinates.

[0029] In addition, various touch input technologies that can be used to sense the touch or movement of a user and recognize the position information of a part of the user's body to control the position information of a pointer can be used in the present invention.

[0030] FIG. 1 is a diagram showing an example of a text input device integrated with a pointing device.

[0031] The text input device with integrated pointing device may have a housing 100 for supporting a text input device and a pointer position information input area.

[0032] The housing has a strength sufficient to withstand the pressure of user input, and may be composed of a control unit, a memory unit, a battery unit, an encoding unit, a transmitting unit, etc. for receiving text input information and pointer position information and transmitting the information to a digital device connected by wire or wirelessly to the text input device integrated with the pointing device.

[0033] The pointing device integrated text input device may be comprised of a number of buttons 109 for receiving text input information from a user.

[0034] The plurality of buttons 109 may be physical buttons or virtual buttons.

[0035] The physical button may be configured as a button connected to an elastic body, or the button itself may have elasticity so that it moves when it receives pressure from the user and returns to its original position when the pressure is removed.

[0036] The physical button may be connected to an electrical switch, and may be configured in such a way that when a user applies pressure, the button moves and the phase of the switch changes, thereby generating a text input value for the button.

[0037] The physical button has an elastic structure without an electrical switch, and is structured to move in position when pressure is applied by a user and to return to its original position when the pressure is removed by the user. The user's text input information can be generated based on position information obtained by recognizing the user's pressure or gesture by the above-mentioned touch input device.

[0038] The virtual buttons may be configured by displaying text input buttons on a display device.

[0039] The virtual button can display any button by projecting light onto a transparent, semi-transparent or opaque object.

[0040] The virtual buttons are not visually recognized by the user, have unique position information for each piece of text, and can generate corresponding text input information based on the user's pressure or gesture information.

[0041] The pointing device-integrated text input device may have pointing position information input areas 108a and 108b that have at least a portion in common with the text input area 107.

[0042] The pointing position information input areas 108a, 108b are areas located on the surface or upper or lower part of the button for text input, and as shown in FIG. 1, the pointing position information input areas may have at least a portion in common with the text input area.

[0043] The pointing position information input area may include the text input area, or the text input area may include the pointing position information input area.

[0044] The pointing position information input area and the text input area have at least a portion in common, and at least a portion may be used as a pointing position information input area but not as a text input area, and at least a portion may be used as a text input area but not as a pointing position information input area.

[0045] The text input device integrated with a pointing device may have a pointer position information input device 105 configured on or outside the text input device integrated with a pointing device for forming a virtual text input area or a virtual pointing position information input area for inputting text or for inputting pointing position information or for inputting text and pointing position information.

[0046] The pointer position information input device 105 can receive position information and gesture information by detecting a part of the user's body on the surface of the housing 100 or above the housing 100, such as an infrared generator and an infrared receiver, or an RGB camera, or an ultrasonic generator and an ultrasonic receiver, or an infrared generator and an infrared camera.

[0047] The pointer position information input device may be configured with a plurality of devices in order to expand the pointer position information input area or to improve accuracy and sensitivity.

[0048] For example, it may have a pointer position information input device 105b for forming a right-hand text input or pointing position information input area 108b.

[0049] Alternatively, it may have a pointer position information input device 105a for configuring a left-hand text input or pointing position information input area 108a.

[0050] The text input area for the right hand or pointing position information input area 108b can be characterized as including the area of ​​the Jay (J) button on a standard English keyboard.

[0051] The text input area or pointing position information input area 108a for the left hand can be characterized as including an area for the F (F) button on a standard English keyboard.

[0052] The pointer position information input device can be characterized by including all of the areas of the J and F buttons of a standard English keyboard.

[0053] The pointing position information input area may be characterized in that, when the pointing device integrated text input device is connected to a plurality of digital devices having display units, the pointing position information input area is capable of moving a pointer position on the plurality of display units.

[0054] For example, the pointer position information input area can be divided so that it matches each display unit, a separate button that indicates a display unit can be operated to transmit pointer position information on that display unit, or multiple display units can be recognized as a virtual single display unit and pointer position information can be transmitted so that the pointer can move on the virtual single display unit.

[0055] The text input device integrated with a pointing device includes a pointing position information input device that forms a pointing input area and receives pointer position information from a user, and may have a pointer execution command unit 101, 102 for executing at least one function on a button, image, space, icon, or text input field where a pointer moved by the pointing position information input device is located.

[0056] The pointer execution command unit is composed of one or two buttons, each of which is responsible for a first function and a second function, and may be located on the left, right or center of the housing.

[0057] The first function may for example function like a left click of a computer mouse and the second function may for example function like a right click of a computer mouse.

[0058] The pointer execution command unit, which is formed of one or two buttons, can be configured on both the left and right sides of the housing, making it easy to use for both left-handed and right-handed people.

[0059] The pointer execution command unit may be configured to operate by touching a part of the user's body using the touch techniques described above, or by recognizing the obstruction of light, interference with ultrasound, or the shadow of a part of the user's body.

[0060] The pointer execution command unit may be configured with a resilient physical button.

[0061] The pointer execution command unit can be operated using at least one of the text buttons located in the text input area as well as the pointing position information input area.

[0062] The pointer execution command unit can be operated by selecting a physical or virtual text button on the pointing position information input area.

[0063] For example, when a virtual input device is used as a pointing position information input device and a physical button is used as a text input device, a pointer execution command can be generated by inputting pointer position information on the virtual pointing position information input area in the pointing position information input mode and pressing the physical text button located at that position.

[0064] The pointer execution command unit can receive pointer position information from a user by a first gesture within a pointing position information input area, and generate a pointer execution command by a user by a second gesture at the same position.

[0065] The pointer execution command unit may be configured to execute a first function by a first body gesture, a first voice, a first blink, a first mouth movement, or the like of the user.

[0066] The pointer execution command unit may be configured to execute a second function by a second body gesture, a second voice, a second blink, a second mouth movement, or the like of the user.

[0067] A text input device integrated with a pointing device can be configured to have a text input mode in which text information is input via the text input device, and a pointing position information input mode in which pointing position information is input via the pointing position information input device.

[0068] The text input mode and the pointing position information input mode can be switched by a mode switching unit 103 .

[0069] The mode switching unit 103 may be configured by a switch located separately on the housing.

[0070] The mode switching unit 103 can switch modes by detecting at least one text input button included in a text input device or a plurality of text inputs being received simultaneously.

[0071] The mode switching unit 103 can receive control information from a digital device connected to the pointing device-integrated text input device by wire or wirelessly, and can switch modes.

[0072] The mode switching unit 103 can be configured integrally with the pointer execution command unit 102 .

[0073] For example, the pointer execution command unit 102, which responds primarily to a first touch or first pressure and secondly to a second touch or second pressure, is configured to detect the first touch or first pressure in response to a first gesture, such as contact with a part of the user's body, to switch modes, and to respond to a second touch or second pressure in response to a second gesture, such as pressing a button, to generate a pointer execution command.

[0074] The mode switching unit 103 can be configured to have a temporary mode switching mode and a permanent mode switching mode.

[0075] For example, a temporary switching mode can be set to switch from a text input mode to a pointing position information input mode in response to a first touch or a first pressure, and to return to the text input mode when the first touch or the first pressure is removed.

[0076] Alternatively, the temporary switching mode can be set to switch from the pointing position information input mode to the text input mode in response to a first touch or a first pressure, and to return to the pointing position information input mode when the first touch or the first pressure is removed.

[0077] The permanent switching mode can be configured to switch from the text input mode to the pointing position information input mode in response to a second touch, a second pressure, or a press switch, and to maintain the pointing position information input mode even when the second touch or second pressure is removed.

[0078] The pointing device-integrated text input device can temporarily switch modes according to first control information received from a digital device connected by wire or wirelessly.

[0079] The pointing device-integrated text input device can perform permanent mode switching according to second control information received from a digital device connected by wire or wirelessly.

[0080] The mode switching unit 103 can be configured integrally with the pointer execution command unit.

[0081] For example, when a first touch or a first pressure is detected on the pointer execution command unit, a temporary mode change is made from a text input mode to a pointer position information input mode, and when a second touch or a second pressure is detected, a pointer execution command is generated, and when a third touch or a third pressure is applied, a permanent change mode can be set to operate in the pointer position information input mode even if the third touch or the third pressure is removed.

[0082] At this time, it is possible to configure so that a pointer execution command can be input even in the permanent switching mode.

[0083] The mode switching portion may be configured on the left or right side of the housing (106a, 106b).

[0084] The mode switching units 106a and 106b arranged on the left or right side or on the left and right sides of the housing may be configured as virtual or physical buttons and may be configured to operate by sensing a touch input or pressure from a user.

[0085] The mode switching units 106a, 106b arranged on the left or right side or on the left and right sides of the housing may be configured to have an input area of ​​3 cm or more and less than 15 cm along the side surface of the housing.

[0086] The text input device integrated with the pointing device may have a transmitter 104 for transmitting data by wire or wirelessly to an external device or to a digital device including the text input device integrated with the pointing device.

[0087] The digital device is capable of receiving text input and of receiving pointer position information.

[0088] FIG. 2 is a flowchart illustrating an example of an operational procedure for switching between the pointing device and the text device mode.

[0089] The text input device with an integrated pointing device may have a separate power supply unit, or may be supplied with power from an external source via a wire or wirelessly, and may have a separate switch for controlling the power supply unit.

[0090] When power is supplied to the pointing device integrated text input device by the switch controlling the power supply unit, it is determined whether the pointing device integrated text input device is currently in a text input mode or a pointing position information input mode (200).

[0091] If the result of the determination is that the mode is a text input mode, the text input device is activated to receive text input from the user (201).

[0092] The inputted user text input is transmitted (202) to a wired or wirelessly linked digital device.

[0093] If a mode switch to a pointing position information input mode occurs during a text input mode, the text input mode can be switched to the pointing position information input mode.

[0094] Alternatively, it may be configured so that pointing position information can be input simultaneously with text input.

[0095] When the mode is switched to the pointing position information input mode, the user inputs pointing position information (204).

[0096] The input pointer position information is transmitted to a digital device connected by wire or wirelessly (205).

[0097] When the text input device integrated with the pointing device receives the first pointer execution command (206), it transmits the first pointer execution command to the digital device connected by wire or wirelessly (207).

[0098] When the text input device integrated with the pointing device receives the second pointer execution command (208), it transmits the second pointer execution command to the digital device connected by wire or wirelessly (209).

[0099] When the temporary mode switch is released or the permanent mode switch is released, the pointing device-integrated text input device can switch to a text input mode.

[0100] The power switch of the power supply unit can be used to shut down the text input device with integrated pointing device when there is no connected digital device, when the connection is lost, when there is no user input for a predetermined period of time, or when it is controlled by a digital device connected via a wire or wirelessly.

[0101] FIG. 3 shows an embodiment of a configuration of a text input device and a pointing device.

[0102] The text input device integrated with a pointing device may be composed of a first housing 301 including a power supply unit, a control unit, a communication unit, etc., and a second housing 302 for forming a text input area and a pointing position information input area.

[0103] The text input device integrated with the pointing device may have a text input device and a text input area 303 for receiving text input from a user.

[0104] Here, the text input area 303 can be configured by a virtual button or a physical button.

[0105] A pointing position information input device may be configured in the form of a pressure-sensitive or capacitive touchpad and may be located over the physical buttons of the text input device (304).

[0106] Here, when the text input device is configured in a physical touchpad format such as a pressure reducing type or a capacitance type, the touchpad can be used as a text input device and a pointing position information input device, and the mode can be switched by a mode switching unit.

[0107] In this case, a physical touchpad such as a pressure reducing or capacitance type touchpad can be configured as a large area touchpad type pointing device integrated text input device 300, which is configured by a touchpad 304 including multiple text button areas of the text input section.

[0108] Alternatively, a physical touchpad such as a pressure-sensitive or capacitive touchpad can be configured as a multiple-touchpad type pointing device-integrated text input device 310 consisting of multiple touchpads 311 including one text button area of ​​the text input section.

[0109] Alternatively, the input of pointing position information can be received (321) by an infrared camera or an RGB (red light beam) camera 222 positioned at the upper part of the pointing position information input area, and the text input device 320 can be configured as an upper camera-type pointing device integrated type.

[0110] In this case, the upper camera type text input device 320 with integrated pointing device can configure virtual text input button 303 using the upper camera.

[0111] The camera may be located at the bottom of the second housing and configured as a pointing device integrated text input device 330 with a bottom camera 332 configured to receive pointing position information input (331).

[0112] In this case, the lower camera type pointing device integrated text input device 330 can use the lower camera to configure a virtual text input button 303 that replaces the physical text button.

[0113] Alternatively, the device can be configured as a text input device 340 with an integrated transmitting / receiving pointing device, in which input of pointing position information is received via a virtual pointing position information input area 341 consisting of a pair of infrared receivers or ultrasonic receivers that receive information in which infrared or ultrasonic waves transmitted by an infrared transmitter or ultrasonic transmitter are blocked or interfered with by part of the user's body.

[0114] At this time, the paired virtual pointing position information input areas can be used as a virtual text button input means in place of the physical text button by the mode switching section.

[0115] FIG. 4 shows an embodiment of a mode switching unit integrated with a pointer execution command unit.

[0116] In a button-type pointer execution command unit having an elastic body 403 that moves in position according to user pressure and returns to its original position when the pressure is removed, a button 402 to which the user pressure is transmitted, and switches 404, 405 that move in position according to user pressure and generate a pointer execution command when brought together, a mode switching unit 401 that detects the user's touch input on the upper part of the button and switches between a text mode and a pointing position information input mode can be located, forming a mode switching unit 400 integrated with a pointer execution command unit using touch input.

[0117] In a button-type pointer execution command unit having an elastic body 403 which moves in position in response to user pressure and returns to its original position when the pressure is removed, a button 402 to which the user pressure is transmitted, and first switches 404, 405 which move in position in response to a first user pressure and generate a pointer execution command when engaged, the button-type pointer execution command unit can be configured as a mode switching unit 410 integrated with a pressure-distinguishing pointer execution command unit, which is made up of second switch units 411, 412 which are engaged in response to a second user pressure which is smaller than the first user pressure and generate a mode switching execution command.

[0118] In the mode switching unit 410 integrated with the pressure-sensitive pointer execution command unit, the button unit 402 can be moved to a different position and fixed by the elastic body 403 so that it cannot return to its original position.

[0119] In this case, the position where the button is fixed can be set to a position where the second switches 411, 412 are connected and the first switches 404, 405 are not connected, and when the button is fixed, it can be configured to operate in a permanent mode switching mode.

[0120] In the mode switching unit 410 integrated with the pointer execution command unit using touch input, the permanent mode switching switch 414 can be configured to be operated by moving the position of the button, such as by sliding the button, and when additional pressure is applied while the permanent mode switching switch 414 is operating, the pointer execution command switches 404, 405 can be configured to operate.

[0121] The mode switching unit 420 integrated with the pointer execution command unit is composed of a touchpad 421, and can function as a mode switching unit when the contact area of ​​a part of the user's body in contact with the touchpad is within a first predetermined range, and can function as a pointer execution command unit when the contact area is within a second predetermined range.

[0122] FIG. 5 shows an embodiment in which a pointer position information input area is displayed.

[0123] The human interface device of the present invention can be designed to further include pointer position information input area display units 701, 702 for visually displaying the pointer position information input area in the pointer position information input mode.

[0124] The mode switching unit of the present invention is provided separately from the buttons of the text input unit, and can be designed to recognize that a part of the body of the human interface is touched by a part of the user's body and to switch between the text input mode and the pointer position information input mode, so that it operates in the pointer position information input mode when touched and in the text input mode when not touched.

[0125] Here, if the body part used for the mode switching is the right hand (106b), the hand that inputs the pointer position information (108a) can be designed to be the left hand.

[0126] In this case, it is preferable to design the pointer position information input area so that it is closer to the corner opposite the corner where the mode switching unit is located, and the same principle can be used when using the left and right hands in reverse (106a, 108b).

[0127] In contrast, the hand can be designed so that the part of the body used for switching modes is the right hand, and the hand for inputting the pointer position information is also the right hand.

[0128] In this case, it is preferable to design the pointer position information input area so that it is closer to the corner where the mode switching unit is located than the corner beyond the corner where the mode switching unit is located, and the same principle can be used for designing in the case of the left hand.

[0129] The mode switching unit can determine between the text input mode and the pointer position information input mode according to the number of the user's fingers recognized by the pointer position information input unit.

[0130] The number of the recognized fingers of the user when determining in the pointer position information input mode is less than the number of the recognized fingers of the user when determining in the text input mode.

[0131] For example, while controlling the mode switching unit with the left hand, the fingers of the left hand are not touching the text input button, and the index finger of the right hand is touching to input pointer position information, and at this time, the number of fingers of the recognized user is one.

[0132] On the other hand, if the fingers of the left and right hands are touched onto the keyboard to input text, the number of the recognized fingers of the user may be from two to eight or less.

[0133] The pointer position information input mode display unit can temporarily display the pointer position information input area when the mode switching unit switches to the pointer position information input mode, or can visually display the pointer position information input area from the time the pointer position information input mode is switched to until the time the mode is released.

[0134] The pointer position information input mode display portion may be displayed from the text input buttons by a visible light generator, or by reflected light from the text input buttons, or through the spaces between the text input buttons.

[0135] The pointer position information input mode display unit is composed of invisible light generators 701a, 701b and surfaces 702a, 702b coated with a dye that optically reacts to the invisible light and emits visible light, and the dye can be applied to the text input buttons or the spaces between the text input buttons.

[0136] The mode switching unit may further include a hand side determination unit that determines whether the user inputs the pointer position information with the left hand or the right hand.

[0137] The hand-side determination section can dynamically display the display area of ​​the pointer position information input / display section.

[0138] The hand-side determination unit can dynamically switch the arrangement and operation of the buttons of the pointer execution command unit.

[0139] For example, if the pointer execution command unit includes right-clicking and left-clicking of a mouse, the button for right-clicking and left-clicking of the mouse can be switched according to the judgment of the hand-side judgment unit.

[0140] The pointer position information input area display unit can display (702a, 702b) different pointer position information input areas according to the judgment result of the hand-side judgment unit.

[0141] The mode switching unit can be designed to automatically switch to the text input mode when, during the pointer position information input mode, no pointer position information is input from the user for a predetermined period of time, or when input is received via a text input button.

[0142] The pointer position information input area display unit can be configured to apply dye to the text input button or part of the text input area so that the pointer input area is visually displayed regardless of the mode of the mode switching unit, making it possible to recognize the pointer input area even in the text input mode.

[0143] FIG. 6 shows an embodiment of a mode switching unit integrated with a pointer execution command unit.

[0144] When performing input work that involves frequent switching between a text input mode and a pointer position information input mode, the number of mode switches and pointer execution commands that must be input increases.

[0145] For example, if you are right-handed and want to input pointer position information while inputting text in a text input mode, you must switch modes with your left or right hand, input the pointer position information, and then input it into the pointer real name command section with your left hand.

[0146] Generally, when a user is performing urgent work, the user will keep his / her eyes on the monitor while inputting text, pointer position information, and pointer execution commands. However, if the mode switching unit and the pointer execution command input unit are provided separately, the user will have to move his / her hands frequently, making it difficult to find the correct position, and the user will be unable to properly execute the function or will have to look at the keyboard, making the work cumbersome.

[0147] To solve this problem, for example, if a right-handed person inputs text in text input mode, and then places his / her left hand on the mode switching unit, a mode switching command is generated and the mode is changed to pointer input mode. Then, with the hand on the mode switching unit, the right hand inputs pointer position information, and if pressure is applied to the mode switching unit, the pointer execution command unit receives the user's input.

[0148] This allows the user to share the location of the mode switching portion for switching modes and the location of the pointer execution command portion for the pointer execution command.

[0149] As one example of this, the mode switching unit is configured as a touch switch that can accept touch input from the user's hand, and the pointer execution command unit is configured as a switch that responds to pressure, such as a tactile switch, and is located below the mode switching unit.

[0150] Here, the first pointer execution command unit 1104 and the second pointer execution command unit 1105 are connected to each other by a conductive material that can recognize the touch of the user's hand, or are commonly connected by the mode switching unit 1201, so that mode switching is performed in the same way whether the user touches the first pointer execution command unit or the second pointer execution command unit.

[0151] At this time, the mode switching operates in the pointer position information input mode while the touch is being performed, and operates in the text input mode when the touch is released.

[0152] Mode switching by touch can be achieved by, in addition to touch, another switch that operates with a pressure smaller than that required for a pointer execution command, or a sensor that can sense the position of the user's finger.

[0153] In this case, the mode switching and pointer execution command unit is located in an area that is distinct from the text input area. Preferably, in the case of a right-handed person, it is located in an outer left area of ​​the text input area. By locating the mode switching unit and the pointer execution command unit outside the text input area, there is no possibility that the pointer position information input unit will be confused with the pointer position information input, and the pointer position information input area can be expanded.

[0154] The composite human interface device of the present invention may include a second mode switching unit 1202. The second mode switching unit is a switch that operates like a toggle switch, and is switched between a text input mode and a pointer position information input mode every time an input is received from a user. This allows the user to input pointer position information with only the right hand, even if the user is not touching the mode switching unit with the left hand.

[0155] Here, when the composite human interface device receives a touch-based mode switching command during the text mode through the second mode switching unit, the composite human interface device of the present invention operates in a pointer position information input mode. Also, when the composite human interface device receives a touch-based mode switching command during the pointer position information input mode through the second mode switching unit, the pointer position information input mode is maintained, but when the touch-based mode switching command is released or text input is received at the text input unit, the mode is switched to the text input mode.

[0156] At this time, if the mode can be switched to the text input mode by inputting text, at least the first text input is ignored, and the mode is switched to the text input mode when at least two or more text inputs are received.

[0157] In this case, when at least two or more text inputs are received and the mode is switched to a text input mode, the composite human interface device transmits a text input including at least the first ignored text to the digital device, and then transmits newly input text input information to the digital device.

[0158] FIG. 7 shows an embodiment in which a cover of the composite human interface device is utilized.

[0159] The composite human interface device requires a space of at least 1 to 2 millimeters above the plane of the text input device, which is constructed of a physical device, in order for the pointer position information input device to form a pointer position information input area, and a frame for positioning an absorber or reflector for absorbing or reflecting optical signals is required at least on three corners surrounding the text input area.

[0160] In this case, a difference of at least 1 to 2 mm occurs between the height of the frame at the corners of at least three sides and the height of the plane of the text input area, forming a substantially rectangular parallelepiped type space.

[0161] The composite human interface device of the present invention may further comprise a multi-purpose cover 1322 for protecting the text input area in the substantially rectangular parallelepiped type space from external impact (1310).

[0162] The multi-purpose cover 1322 is separate from the composite human interface device (1320) and can be connected and disconnected by magnets or physical structures.

[0163] The multi-purpose cover 1322 may be folded several times, preferably twice, and the width of at least one of the divided areas of the multi-purpose cover may be smaller than the width of the other areas (1341).

[0164] This allows the composite human interface device to have a smaller inclination when the multi-use cover is attached to the lower part to adjust the inclination of the composite human interface device after it is folded.

[0165] When the multi-purpose cover is folded and then attached to the underside of the composite human interface device, the portion of the folded surface that comes into contact with the ground may have an inclined surface 1342 so that the area that comes into contact with the ground is increased.

[0166] The user can adjust the inclination of the composite human interface device as desired by changing the number of times the multi-purpose cover 1322 is folded.

[0167] The multi-purpose cover may incorporate a rechargeable battery 1323 inside the cover.

[0168] The power source of the rechargeable battery 1323 may have electrodes located in a part of an area that covers the frame of the part covering the text input area of ​​the lower part of the multi-purpose cover and protrudes from the part covering the text input area (1331), and when the multi-purpose cover covers the text input device (1310), it is connected to electrodes provided on the upper part of the composite human interface device.

[0169] In addition, when the multi-purpose cover is folded and attached to the lower part to adjust the inclination of the composite human interface device, it can be connected to the electrodes provided on the lower surface of the composite human interface device.

[0170] The composite human interface device can be connected to an external power source to power a rechargeable battery 1323 inside the utility cover or to charge the utility cover separately.

[0171] In this case, the bottom surface of the composite human interface device may have the protruding frame region where the electrodes 1331 are located, a region 1332 that covers a text input region of a different height, and a groove into which a magnet or a physical coupling device or a cover can be inserted so that it can be attached and detached at a precise position.

[0172] The frame of the multi-purpose cover is coated with a material capable of removing fine dust, oil stains, moisture, etc., and can remove foreign matter from the absorber or reflector, optical emitter, and front part of the camera every time the multi-purpose cover is attached to or detached from the composite human interface device.

[0173] If the multi-purpose cover covers the text input area, this can be detected and the composite human interface device can be powered off.

[0174] When the multi-use cover is attached to the underside of the composite human interface device, the composite human interface device can be powered on.

[0175] Also, if there is no user input for a predetermined period of time after the power is turned on, the power can be cut off or the device can be switched to a standby mode.

[0176] When the multi-purpose cover covers the text input area (1310), the composite human interface device 1321 has a substantially thin, plate-like rectangular shape and is designed not to tilt when placed on the ground, thereby maximizing the aesthetic effect and increasing portability.

[0177] On the other hand, when the multi-purpose cover is folded and attached to the bottom surface of the composite human interface device, it is possible to ensure an inclination like a general keyboard.

[0178] The multi-purpose cover may be detachable and may be designed to be folded by being rolled up from the top to the bottom of the composite human interface device by a hinge.

[0179] FIG. 8 shows an embodiment of a human interface device applied to a portable notebook computer.

[0180] The human interface device 1420 of the present invention can be utilized as an input device for a portable notebook computer.

[0181] A portable notebook computer equipped with the human interface device of the present invention can be designed so that a display unit consisting of a display panel 1411 and a frame 1410 supporting the display panel is connected to the human interface device of the present invention by a hinge 1427 and can be designed to have an openable and closable structure.

[0182] Here, the display unit is inserted inside the wall formed by the reflector or absorber 1424 of the human interface device of the present invention, so that the thickness of the portable notebook computer using the human interface device of the present invention can be minimized.

[0183] For this purpose, the display unit of the portable notebook computer must be designed so that the width and length of the human interface device 1420 of the present invention are at least twice the thickness of the reflecting or absorbing plates 1423 and 1424 .

[0184] In other words, the display unit must be designed to go where the multi-use cover goes in FIG.

[0185] The display unit is characterized by having both corners rounded or beveled (1413).

[0186] The pointer position information input devices 1421 and 1422 are characterized in that, when the display unit is closed, they are positioned on the outer corners of the rounded or obliquely cut portion.

[0187] This is because when the portable notebook computer is closed, it is closed without being obstructed by the pointer position information input devices 1421 and 1422 and can maintain a thin thickness.

[0188] In this case, the mode switching unit and the pointer execution command unit can be located outside the side surface of the human interface device.

[0189] More preferably, it may be located below and outside the text input area (1425, 1426).

[0190] In this case, it is preferable that the mode switching section and the pointer execution command section are configured as an integrated unit as shown in FIG. 12, but they may also be located separately.

[0191] Here, when the mode switching unit or the pointer execution command unit is located below and outside the text input area, the pointer position information input area must be set excluding the area where the mode switching unit or the pointer execution command unit is located, so that when the user positions his / her finger to control the mode switching unit or the pointer execution command unit, the pointer position information input device 1421, 1422 does not malfunction when the user inputs the pointer position information.

[0192] For this purpose, the area covered by the optical signal generated from the pointer position information input device can be adjusted so as to prevent the optical signal from reaching the mode switching unit or the pointer execution command unit.

[0193] Alternatively, the camera's optical signal receiving angle can be adjusted so that the camera cannot receive optical signals generated by reflection, interference, or blockage between the optical signal and the user's finger positioned at the mode switching unit or pointer execution command unit, or the optical signal received from that direction can be ignored.

[0194] The portable notebook computer is designed to have an absorbing or reflecting plate at at least three corners for absorbing or reflecting the light emitted from the pointer position information input device.

[0195] In this case, two surfaces are located on the sides of the human interface device (1423, 1424), and the other surface is a surface where the display unit abuts against the human interface device, and when the display unit is opened within a specified angle, a reflector or absorber is positioned in a specified area 1412 so that the light source generated by the pointer position information input devices 1421, 1422 is sufficiently reflected or absorbed.

[0196] FIG. 9 shows an embodiment in which a lower-position type pointer position information input device and a lower-position type pointer execution command unit are applied.

[0197] The human interface device includes a text input unit 1501 having a plurality of physical buttons, a pointer position information input unit for inputting information related to a pointer position from a user, a pointer execution command receiving unit for receiving a signal from pointer execution command units 1505 and 1506 for inputting a user command to perform at least one function at a position where the pointer is located, a mode switching command receiving unit for receiving a signal from a mode switching unit for switching to a pointer position information input mode, and a pointer position information receiving unit for transmitting the information related to the pointer position inputted to the pointer position information input unit to a digital device connected to the human interface device by wire or wirelessly. and a pointer position information transmitting unit, a pointer position information input area of ​​the pointer position information input unit is located parallel to an upper part of at least a part of a text input area of ​​the text input unit formed by the plurality of physical buttons, the pointer position information input unit includes optical signal reflectors or absorbers 1503a, 1503b, 1503c formed higher than the height of the text input unit on first to third surfaces 1502a, 1502b, 1502c surrounding the text input unit, and a fourth surface 1502d surrounding the text input unit is formed lower than the height of the first to third surfaces, and the fourth surface may include the pointer execution command units 1505, 1506. The first surface and the third surface may be located on the left and right sides of the text input unit, respectively, the second surface may be located above the text input unit, and the fourth surface may be located below the text input unit.

[0198] The pointer position information input unit may include at least two sensor modules, and the two sensor modules may be located in corner regions of the lower left and lower right sections of the text input unit, respectively.

[0199] The mode switching unit may be operated by a first user input inputted to a first button, and the pointer execution command receiving unit may be operated by a second user input inputted to the first button.

[0200] The first button is made of a material capable of sensing an electrical signal generated by a finger touch, and the first input can be generated by recognizing the electrical signal.

[0201] While the first input is maintained, the touch panel operates in the pointer position information input mode, and when the first input is released, the pointer position information input mode is released. The first input may be generated by physical pressure.

[0202] The mode switching unit operates in response to a second input by a user inputted to a second button, and when the second input is input once, the mode switching unit can activate the pointer position information input mode if it is deactivated, or can deactivate the pointer position information input mode if it is activated.

[0203] At this time, it is preferable that the light source and image receiving device generated by the pointer position information input devices 1421 and 1422 are directed toward the center of the keyboard.

[0204] However, if the keyboard is small or in order to secure a larger pointer position information input area, the absorbing or reflecting plates 1423, 1424 located on the sides of the human interface device can be replaced with reflecting plates rather than absorbing plates, and the light sources and image receiving devices of the pointer position information input devices 1421, 1422 can be arranged to face the reflecting plates 1423, 1424.

[0205] That is, the pointer position information input device 1421 can receive the pointer position information reflected by the reflector 1423 .

[0206] Furthermore, the pointer position information input device 1422 can receive the pointer position information reflected and received by the reflector 1424 .

[0207] This provides the effect of positioning the pointer position information input devices 1421 and 1422 outside the left and right sides of an actual composite human interface device, thereby making it possible to obtain a wider mouse pointer position information input area.

[0208] At this time, the angle of the reflectors can be set to a predetermined angle of 1 to 15 degrees. That is, the lower stage of the reflectors 1423 and 1424 can be set to open more than the upper stage.

[0209] This provides the effect of positioning the pointer position information input devices 1421 and 1422 outside the left and right sides of the actual composite human interface device, and at the same time, provides the effect of moving them a certain distance above the keyboard so that they are not obstructed by the pointer execution command input device located at the bottom of the keyboard.

[0210] The composite human interface device includes a reflecting unit that reflects the light source generated from the pointer position information input unit, at least two of the pointer position information input units are provided on the left and right sides of the human interface device, the reflecting units are provided on the left and right sides of the human interface device, the left pointer position information input unit is provided facing the left reflecting unit and receives the light source input via the left reflecting unit, and the right pointer position information input unit is provided facing the right reflecting unit and receives the light source input via the right reflecting unit.

[0211] The left and right reflecting parts may not be parallel to each other, but may be provided to open toward the left and right pointer position information input parts.

[0212] The pointer position information input area may be divided into a first area and a second area, that is, for example, a pointer position information input signal input from a right hand is received from the first area, and a pointer position information input signal input from a left hand is received from the second area.

[0213] Generally, a multi-touch control receives a plurality of touch input signals and then determines a control command according to the subsequent movement manner of the plurality of touch input signals.

[0214] However, in this embodiment, the first pointer position information input signal received from the first pointer position information input area can be used to grasp the number of touch inputs.

[0215] And, the second pointer position information input signal received from the second pointer position information input area can be used to receive a movement signal of a touch input.

[0216] That is, for example, if a user inputs an up and down slide touch input with one finger of the right hand while maintaining two finger touch input with the left hand, this signal can be replaced with a general multi-touch function of two touch signals for up and down touch input. Generally, an example of an up and down slide touch input with two touches on an Apple Macbook is an up and down scroll input on an Internet browser. In this case, if a user taps with one finger of the right hand, the touch input of the left hand is two, so the same function can be performed as if the user tapped with two fingers.

[0217] As another example, when a left / right slide touch input is input with the right hand while maintaining three touch inputs with the left hand, this signal can be replaced with a left / right slide touch input with three touch signals of a general multi-touch function. Generally, in an Apple MacBook, a left / right slide touch input with three touches is exemplified as a full-screen app swipe or a three-finger drag. In this case, when a tap is made with one finger of the right hand, the left hand makes three touch inputs, so that the same function can be performed as when a tap is made with three fingers. The above example of left and right hands can be replaced with an example of right and left hands, and the number of input signals determining the number of touches is not limited to the above two and three, but may include one, four, or five touches.

[0218] The information related to the pointer position received by the pointer position information input unit may be composed of information related to a first pointer position for moving the pointer position, and information related to a second pointer position for switching the human interface device from a text input mode to a pointer position information input mode.

[0219] For example, if a pointer position information input signal having a value equal to or greater than a preset threshold occurs during text input mode, the mode can be switched to a pointer position information input mode.

[0220] FIG. 10 is a diagram showing the configuration of the multi-function input button.

[0221] The multi-function input button may be a single button for constituting a text input device 310 with an integrated pointing device, which is configured by combining a character input unit 303 for inputting at least one character in a human interface such as a keyboard, and a physical touchpad 311 such as a capacitive touchpad for inputting pointing position information for moving a mouse pointer or inputting a user's touch or 3D gesture on the screen.

[0222] In this embodiment, a capacitive touch type is used as the pointing position information input unit, but the contents of the mode switching unit, pointer execution command input unit, special function keys, positions of the mode switching unit and pointer execution command unit, connection with the interior or display unit, method of incorporating a battery using the cover unit, angle adjustment function of the human interface device, text character input area and mouse pointing position information input area, etc. of the composite human interface device described above using the optical type pointing position information input unit can be similarly applied.

[0223] The pointing device-integrated text input device 310 may be configured with a number of multi-function input buttons.

[0224] The multi-function input button may be composed of a cover part 1010 that is touched by a user's finger, an electrode part 1020 including a transmitter and a receiver for forming an electric field, and a base part 1030 for protecting the electrode part and ensuring connectivity with the elastic part.

[0225] The elastic portion may be composed of an elastic body 1050 , an upper support portion 1040 , and a lower support portion 1060 .

[0226] The upper support part and the lower support part are configured in a cylindrical shape or a polygonal tube shape with corners, and the upper support part and the lower support part move in position via an elastic body, and the lower support part can guide the movement of the upper support part.

[0227] The upper support portion may be fixed to the cover portion, the electrode portion, and the base portion.

[0228] The lower support may act as a guide for the reciprocating movement of the upper support.

[0229] The upper and lower support parts may have a pantograph structure to connect an upper structure including an electrode part and a lower structure including an elastic part, and guide the movement of the upper structure.

[0230] The elastic body may be a dome-shaped elastic material with a resilient force, a plate-shaped elastic material with a resilient force, a spring-shaped elastic material, a plurality of magnets with opposite polarities facing each other, or a combination thereof.

[0231] The elastic part may move to a third height when receiving a second pressure from the cover part, and may be restored to the first height when the second pressure from the cover part is released. The movement to the third height may mean that a physical position is moved, an object is warped due to pressure, or the second pressure is sensed by software, etc.

[0232] When the first pressure is sensed, a pointer execution command may be generated, and when the second pressure is sensed, an additional pointer execution command may be generated.

[0233] For example, a first pressure may indicate an instruction to run an application at the location of the pointer, and a second pressure may provide additional options or a preview of the application.

[0234] The electrical signals indicating the input of the predetermined characters generated through the switches of the first to fifth composite function input buttons are electrical signals indicating input of different characters, and the contact position or change in the contact position of the user's finger determined from the signals received through the electrodes of the first to fifth composite function input buttons may be for controlling the position of one pointer in a connected manner.

[0235] The human interface device may further include a mode switching unit for switching between a character input mode and a pointing position information input mode.

[0236] The mode switching unit may be operated by the multi-function input button, a separate physical switch unit, a touch switch unit, or a predefined touch pattern.

[0237] The human interface device can generate pointing position information for continuously controlling a single pointing input device on electrodes of a character input device composed of a combination of multiple multi-function input buttons capable of inputting one character, and the multiple multi-function input buttons.

[0238] Apart from the multiple function input buttons, the human interface device may comprise a mode switching section and a pointer execution command section.

[0239] The mode switching unit and pointer execution command unit is a single button composed of an electrode and a switch that can recognize the user's touch, and after switching modes by touch, a pointer execution command can be generated by a pressure signal without the need to move or release the finger.

[0240] The multi-function input button may include a light emitting portion 1070 .

[0241] The light emitting section can illuminate characters that indicate input of characters on the multi-function input button, or can illuminate the position of the multi-function input button itself.

[0242] The light emitting portion may be located on an upper structure including an electrode, or on a lower structure including an elastic body.

[0243] The upper structure includes an electrode portion and is a portion that moves according to the pressure of a user, and may include a cover portion, an electrode portion, a base portion, and the like.

[0244] The lower structure may be a portion that guides the movement of the upper structure and does not move when pressure from a user is applied, the portion including a structure that transmits or receives an electrical signal to the electrode portion.

[0245] FIG. 11 shows an embodiment of electrodes for a multi-function input button.

[0246] The electrode section of the electrostatic touch system is composed of a plurality of transmitters and receivers.

[0247] In a typical electrostatic touch system, the electrode section is configured in a lattice shape with 5 to 30 columns of transmitter sections and 5 to 30 rows of receiver sections, forming a square surface of a predetermined size.

[0248] In this embodiment, the multi-function input button may be configured with an electrode portion the size of one character input button, typically having a width of 10 to 20 mm.

[0249] The electrode unit may independently configure a small touch pad and be used as a pointing position information input device, and may be used together with a plurality of adjacent multi-function input buttons as a pointing position information input device having connectivity over a wider area.

[0250] The electrode section may be composed of one to three transmitters and receivers.

[0251] In this embodiment, the electrode portion of one composite function input button is described as an example of a composite function input button composed of three rows of transmitters having different drive signal periods and two rows of receivers having different scan periods.

[0252] Here, the period may refer to the timing at which a signal is generated.

[0253] The present invention includes a portion in which the number and shapes of transmitters and receivers can be easily modified by those skilled in the art according to the size and shape of the button.

[0254] There may be a first transmitter 1101, 1102, 1103 having a first drive period, a second transmitter 1104, 1105, 1106 having a second drive period, and a third transmitter 1107, 1108, 1109 having a third drive period.

[0255] There may be a first receiver 1110, 1111 having a first scan period and a second receiver 1112, 1113 having a second scan period.

[0256] The first to third transmitters may be shorted on a circuit board or may be connected together without a separate connecting member.

[0257] The first and second receivers may be printed on a circuit board in a state where they are shorted to each other and connected by a separate connecting member, or may be configured to be independently scanned for electrical signals such as capacitance in the same scanning period.

[0258] In the present embodiment, the electrode portion requires a special design in order to move each composite function input button up and down while the multiple electrode portions configured on the multiple composite function input buttons are recognized as if they were one large-area electrode portion.

[0259] For example, the area of ​​the second transmitter may be greater than the combined area of ​​the first and third transmitters.

[0260] The combined area of ​​the first to third transmitters may be smaller than the combined area of ​​the first and second receivers.

[0261] In a typical capacitive touchpad, receivers having one scan cycle are connected to each other, but in this embodiment, a first receiver having one scan cycle is composed of at least two receiver blocks 1110 and 1111, and the at least two receiver blocks can transmit a scan signal to the outside while being shorted to each other.

[0262] The scan signal can be processed by combining the capacitance signals received from the respective receiver blocks.

[0263] In this embodiment, an example is given in which the transmitter is arranged horizontally and the receiver is arranged vertically, but the receiver can be arranged horizontally and the transmitter vertically on the same structure.

[0264] The transmitter and receiver may be electrically shorted by insulators 1114, 1115.

[0265] The electrode section may include a bridge 1120 that is stacked or connected below and transmits and receives external drive signals and scan signals.

[0266] The bridge may transmit a drive signal to the electrode portion and receive a capacitance signal from the receiver.

[0267] FIG. 12 shows an example of a multi-function input button layout.

[0268] In this embodiment, the composite human interface device configured with a plurality of composite function input buttons can include at least five composite function input buttons.

[0269] A second composite function input button 1220 and a third composite function input button 1230 are located on the left and right sides of the first composite function input button 1210, respectively, and the center points of the second composite function input button are arranged on an imaginary X-axis line extending left and right from the center point of the first composite function input button, and the center point of the third composite function input button is arranged on an imaginary X-axis line extending right from the center point of the first composite function input button.

[0270] The touch panel may further include a fourth composite function input button 1240 and a fifth composite function input button 1250, wherein the center point of the fourth composite function input button is located on the left side of a virtual Y-axis extending upward from the center point of the first composite function input button and is located on the right side of a virtual Y-axis extending upward from the center point of the second composite function input button, the center point of the fifth composite function input button is located on the right side of a virtual Y-axis extending downward from the center point of the first composite function input button and is located on the left side of a virtual Y-axis extending downward from the center point of the third composite function input button, and the fourth and fifth composite function input buttons may be located adjacent to the first composite function input button.

[0271] The distance that the center point of the fourth composite function input button is spaced to the left from an imaginary Y-axis extending upward from the center point of the first composite function input button may be shorter than the distance that the center point of the fifth composite function input button is spaced to the right from an imaginary Y-axis extending downward from the center point of the first composite function input button.

[0272] For example, the fifth composite function input button is positioned 40 to 60 percent of the width of the first composite function input button to the right from the Y axis.

[0273] The fourth composite function input button is positioned 15 to 35 percent of the width of the first composite function input button to the left of the Y axis.

[0274] The first transmitters of the first to third multi-function input buttons may have the same drive signal period as the third transmitter of the fourth multi-function input button.

[0275] The second receiver of the first multi-function input button may have the same scan period as the first receiver of the fifth multi-function input button.

[0276] The first receiver of the first multi-function input button and the second receiver of the fifth multi-function input button may have different scan periods.

[0277] The second receiver of the first composite function input button and the second receiver of the fourth composite function input button may not be arranged in a line in the virtual Y-axis direction, but may be shifted to the left within the width of the first composite function input button, and the second receiver of the first composite function input button and the second receiver of the fourth composite function input button may have the same scan period.

[0278] This may result in distortion of the pointing position information signal, which may require an additional step of correction by software.

[0279] The human interface device further includes a sixth composite function input button 1560, the center point of which is located on a virtual Y-axis extending downward from the center point of the fifth composite function input button.

[0280] FIG. 13 shows an example of electrode arrangement of different patterns of a multi-function input button.

[0281] The first composite button input button and the fourth composite button input button may not be aligned in a line on the imaginary Y axis, but may be shifted to the left by a first distance.

[0282] This may cause signal distortion in the receiver of the first composite button input button and the fourth composite button input button.

[0283] In order to prevent this or minimize the distortion, the pattern of the fourth composite input button can be modified and designed.

[0284] For example, the electrode pattern of the first distance from the left side of electrode 1130 shown in FIG. 11 may be configured into a second electrode shape 1350 that is shifted to the right side of the electrode.

[0285] The shape of the second electrode has the effect of aligning the receivers of the first and fourth multi-function input buttons along an imaginary Y-axis.

[0286] A seventh composite function input button 1360 configured in the shape of the second electrode may be located to the right of the fourth composite function input button.

[0287] Here, the scan period of the receiver 1351 located at the rightmost position of the fourth multi-function input button may be the same as the scan period of the receiver 1361 located at the leftmost position of the seventh multi-function input button. In this case, the second receivers 1112 and 1113 of the first multi-function input button may also have the same scan period.

[0288] FIG. 14 shows an embodiment of an electrical connection member for a multi-function input button.

[0289] The transmitters of the first, second and third multi-function input buttons may be connected to each other by a first electrical connecting member, and the receivers of the first, fourth and fifth multi-function input buttons may be connected to each other by a second electrical connecting member.

[0290] In a first embodiment of the connecting member, the connecting member may be composed of a first conductor that contacts or is joined to an electrode portion and moves together with the electrode portion when pressure is actually applied to the multi-function input button to move it from a first height to a second height, a second conductor that is provided on a stationary part of the multi-function input button and receives an electrical signal from the first conductor, and a PCB that connects to the second conductor of a nearby multi-function input button.

[0291] The base PCB can simultaneously transmit and receive drive signals and scan signals from the control unit to the transmitters and receivers of a plurality of multi-function input buttons.

[0292] The first conductor and the second conductor abut against each other in a sliding manner and can move while maintaining their connection.

[0293] The first conductor and the second conductor may be configured to maintain contact when no pressure is applied to the multi-function input button or when pressure equal to or less than a predetermined threshold is applied, and to maintain contact and be short-circuited when pressure equal to or greater than a predetermined threshold is applied.

[0294] The first and second conductors may be configured in a non-contact manner 1450. The first and second conductors may be provided in the form of conductive plates having a predetermined area and may face each other at a predetermined distance.

[0295] The predetermined gap may be filled with a non-conductive material 1443 having a dielectric constant, such as air, plastic, silicone, glass, or porcelain.

[0296] In this case, the electrical signal may be transmitted in the form of a radio signal having a frequency.

[0297] This has the advantage that it is possible to reduce wear of the conductors and noise in the signals due to friction between the first and second conductors, minimize the occurrence of friction that interferes with the pressure applied to the multi-function input button, and simplify the manufacturing process.

[0298] At least one of the first and second electrical connection members may be a conductive material printed on a flexible film together with the electrode portion, or may be an electrical connection member provided on the elastic portion in close contact with or bonded to the electrode portion.

[0299] FIG. 15 shows an embodiment of a switch for character input of a multi-function input button.

[0300] When pressure is applied to the multi-function input button to move it from a first position to a second position, switches 1511, 1512, 1513 can be actuated which produce an electrical signal indicative of the input of a predetermined character.

[0301] When switches 1512, 1523 located on the base PCB or a separately provided membrane are connected to a terminal 1511 located on the moving portion of the multi-function input button, an electrical signal indicating the input of a predetermined character can be generated and transmitted to a control unit.

[0302] The switch may be a separate push switch, or may be activated by sensing a change in magnetism or electric field, light intensity, sound, or the like.

[0303] FIG. 16 shows an embodiment of a human interface device having a multi-function input button.

[0304] FIG. 17 shows an example of an electrode keycap.

[0305] A plurality of electrode keycaps 1700 may be positioned on a common plane to constitute the electrode keycap layer 1620.

[0306] For example, one electrode keycap can accept input of one character depending on the mode, or can sense a certain amount of change in touch position.

[0307] In contrast, the electrode keycap layer can accept input of multiple characters and can sense the amount of change in touch position in proportion to the number of electrode keycaps.

[0308] The multi-function human interface device may include a control portion, a cover portion 1010 for contact with a user's finger, an electrode keycap 1700 including first electrical conductors 1741, 1742, 1713, 1714, 1746, 1748 and electrode portions 1020, 1701, and a second electrical conductor.

[0309] The second conductor may be provided in a first circuit layer 1630.

[0310] When a user's finger touches a cover portion that is in close contact with the upper part of the electrode key cap, the electric field between the transmitter and receiver provided in the electrode is affected, and the capacitance changes.

[0311] The first conductor may be provided in a plurality of pieces, one for each of the transmitter and the receiver of the electrode portion.

[0312] When a drive signal is applied at a predetermined signal period through the first conductor connected to the transmitter, a capacitance is formed between the transmitter and the receiver, and the generated capacitance is transmitted by the receiver through the first conductor connected to the receiver and through a second conductor electrically connected to the first conductor, and a control unit detects a change in the transmitted capacitance.

[0313] The electrode portion is electrically connected to the second conductor via the first conductor, the electrode portion is located on a first surface 1702 of the electrode keycap, and the first conductor may be formed on a pillar formed perpendicular to the first surface with a predefined area.

[0314] At least two pillars may be formed perpendicular to the first surface, and the first conductor may be formed on each of the at least two pillars.

[0315] The electrode portions 1020 and 1701 include a transmitter and a receiver, and the first conductors formed on the at least two pillars, respectively, may be electrically connected to the transmitter and the receiver, respectively.

[0316] The first conductor may be formed around a surface of the pillar.

[0317] The pillar is tubular with a hole 1703 penetrating the pillar, and the hole penetrates both the first surface 1702 and the electrode portion and the first conductor can be electrically connected through the inner wall of the hole.

[0318] The electrode portion has a plurality of pattern blocks 1701 having a specific shape on the first surface, and at least some of the pattern blocks may be electrically connected to each other via a second surface 1731 of the electrode keycap.

[0319] The plurality of pattern blocks 1704 electrically connected via the second surface may be electrically connected to the second conductor via a first conductor 1713 formed on one pillar.

[0320] For example, the three triangular pattern blocks on the top row of the first surface 1702 may be electrically connected by conductors provided on the side 1731 adjacent to the triangular pattern blocks.

[0321] Similarly, the three triangular pattern blocks in the lowest row may be electrically connected to each other by conductors provided on the side surfaces adjacent to the three triangular pattern blocks in the lowest row.

[0322] Here, the three triangular pattern blocks in the uppermost or lowermost row may be electrically connected to one pillar provided on the rear surface through a hole provided in the pillar.

[0323] In addition, the triangle, diamond and triangle pattern blocks lying in the middle are electrically connected on the first surface, and similarly, one pillar on the back surface is electrically connected to the first conductor through a hole provided in the pillar, and the pillar used here is located in the center of the back surface and can also be used simultaneously for the purpose of transmitting pressure to the elastic part.

[0324] In this case, the pattern blocks provided at the top, bottom and middle can transmit transmitter signals and can have different signal periods.

[0325] In addition, the two diamond-shaped pattern blocks arranged horizontally in the upper row and the two diamond-shaped pattern blocks arranged horizontally in the lower row are electrically isolated on the first surface and can be electrically connected to the first conductor through holes provided in pillars provided on the back surface.

[0326] The first conductor may be provided on a plurality of pillars on a rear surface of the electrode keycap.

[0327] The plurality of pattern blocks electrically connected via the second surface may be transmitters having the same signal period.

[0328] The electrode portion has at least three pattern blocks 1704 having a specific shape on the first surface, and the three pattern blocks can be electrically connected to the second conductor via a first conductor formed on one pillar, respectively.

[0329] At least two pattern blocks of the plurality of pattern blocks may have a first signal period and at least one pattern block may have a second signal period.

[0330] The at least three pattern blocks may be receivers.

[0331] The composite human interface device further includes an elastic portion 1050, and the pillar transmits a user's pressure applied to the cover portion to the elastic portion so that the positions of the cover portion and the electrode keycap can be moved from a first position to a second position, and when the user's pressure is released, the pillar receives pressure from the elastic portion so that the positions of the cover portion and the electrode keycap can be restored from the second position to the first position.

[0332] The electrode portion and the first conductor can be formed by plating a conductor onto a non-conductive object consisting of at least one flat plate and at least two pillars connected perpendicularly to the flat plate and having holes penetrating the flat plate and the pillars.

[0333] The electrode portion has a plurality of pattern blocks having a specific shape on the first surface, and a plurality of pillars may be formed on a third surface 1710 located behind the first surface.

[0334] The first conductors may be formed on the plurality of pillars, and the first conductors formed on the plurality of pillars may be electrically shorted by a third surface.

[0335] The electrode portion has a plurality of pattern blocks having a specific shape on the first surface, and the plurality of pattern blocks are electrically connected to a fourth surface 1732 located on one side of the first surface, and the plurality of pattern blocks can be electrically shorted to each other by an electrical short 1733 formed on the fourth surface.

[0336] The pattern blocks are not limited to those illustrated in the drawings, but may include various other patterns such as rectangular and comb-like patterns.

[0337] The composite human interface device may be configured with a plurality of the electrode keycaps, the first conductors provided on the plurality of electrode keycaps transmit electrical signals to a plurality of the second conductors, and the plurality of second conductors may be configured on one first circuit layer 1630.

[0338] The human interface device further includes a light source below the electrode keycap, the pillar is tubular with a hole penetrating the pillar, and the cover is made of a light-guiding material that diffuses light, and can receive light from the light source through the hole and emit light.

[0339] The hole may be used to electrically connect the electrode portion of the electrode keycap and the first conductor by plating.

[0340] However, plating makes the electroplated keycaps opaque, making it difficult to provide the keyboard with the function of illuminating the keys to make it easier to work in dark places.

[0341] However, since a light source can be transmitted through the hole, the hole can be used as an electrical connection path and a light source path.

[0342] The cover portion may have characters guiding the input of text printed or engraved on the surface that comes into contact with the user, or may have a film with holes in the shape of the characters attached thereto.

[0343] The first conductor and the second conductor face each other in a non-contact manner over a predetermined area, and a high-frequency electrical signal can be transmitted in a non-contact manner via the predetermined area.

[0344] For example, if the pillar is cylindrical, the surface facing the first conductor and the second conductor in a non-contact manner may be a strip having a predetermined width, if the pillar is a rectangular pillar, the surface may be a square strip having a predetermined width, or the first conductor may be provided only in a partial region of the pillar, to realize a facing portion of a desired shape and area.

[0345] 18 to 22 show an embodiment of electrode patterns for multiple composite function input buttons.

[0346] The composite human interface device may be used in various electronic devices, such as a desktop input device, an input device for a tablet PC, an input device for a notebook computer, an input device for controlling a home theater, an input device for controlling multimedia in an autonomous vehicle, an input device for virtual reality or augmented reality, etc.

[0347] The electronic device equipped with the composite human interface may include first to fifth composite function input buttons.

[0348] The first to fifth multi-function input buttons are each capable of receiving input of different characters and a touch input for controlling one piece of pointer position information from a user.

[0349] The first to fifth multi-function input buttons may be positioned without being aligned on the X-axis or the Y-axis, respectively.

[0350] For example, the first to third multi-function input buttons are aligned in a row in the X-axis direction, and the fourth and fifth multi-function input buttons are positioned above and below the X-axis, respectively.

[0351] Additionally, the fourth multi-function input button 1240 may not be aligned with the first multi-function input button along the Y axis, but may be spaced about 25 percent to the left.

[0352] The fifth multi-function input button 1250 may be misaligned with the first multi-function input button along the Y axis and may be positioned approximately 50 percent to the right.

[0353] In order for the first to fifth composite function input buttons to control one pointer position information, the multiple transmitters and the multiple receivers must be aligned in a row with transmitters having the same drive signal and aligned in a row with receivers having the same scan signal period.

[0354] In contrast, since the first to fifth multi-function input buttons are not aligned in a line with respect to the X-axis or the Y-axis, the multi-function input buttons have two to four receivers or transmitters parallel to the X-axis or the Y-axis, so that the receivers or transmitters can be aligned even though the multi-function input buttons are not aligned in a line with respect to the X-axis or the Y-axis.

[0355] Each of the composite function input buttons may be composed of electrode sections 1020a, 1020b, 1020c, 1020d, 1020e, 1020f, 1020g, 1020h, 1020i, 1020j, 1020k, and 1020l, each of which is composed of a transmitter section T1, T2, T3, or T4 and a receiver section R1, R2, R3, or R4.

[0356] The electrode portion may include transmitters parallel to the X-axis and receivers parallel to the Y-axis (1020a, 1020c, 1020e, 1020g, 1020i, 1020k).

[0357] In the embodiments described below, the electrode section will basically be described as having a transmitter parallel to the X-axis and a receiver parallel to the Y-axis. However, even if not specifically described, the same configuration is possible for a configuration in which the transmitter and receiver are interchangeable, i.e., a receiver parallel to the X-axis and a transmitter parallel to the Y-axis.

[0358] The electrode portion may include transmitters parallel to the Y axis and receivers parallel to the X axis (1020b, 1020d, 1020f, 1020h, 1020j, 1020l).

[0359] FIG. 18 is an example of an electrode pattern for multiple composite function input buttons, and the electrode portion may include four transmitters and four receivers.

[0360] In the embodiment described below, an embodiment will be described based on four transmitters parallel to the X-axis and four receivers 1020a parallel to the Y-axis, but the same explanation can be applied to four receivers parallel to the X-axis and four transmitters 1020b parallel to the Y-axis.

[0361] The transmitter section may include first to fourth transmitters having at least two driver signal periods, and the receiver section may include first to fourth receivers R1, R2, R3, R4 having at least two mutually different scan signal periods.

[0362] The first receiver of the fourth multi-function input button 1240 may have the same scan signal period as the fourth receiver of the second multi-function input button 1220 .

[0363] The second receiver of the fourth multi-function input button 1240 may have the same scan signal period as the first receiver of the first multi-function input button.

[0364] The third receiver of the fourth multi-function input button may have the same scan signal period as the second receiver of the first multi-function input button.

[0365] The fourth receiver of the fourth multi-function input button may have the same scan signal period as the third receiver of the first multi-function input button and the first receiver of the fifth multi-function input button 1250 .

[0366] The electronic device equipped with the composite human interface has a sixth composite function input button 1260, which is aligned and adjacent to the fifth composite function input button on the Y axis, and the first to fourth receivers of the sixth composite function input button may have the same scan signal period as the first to fourth receivers of the fifth composite function input button, respectively.

[0367] In contrast, the fifth and sixth multi-function input buttons may have different driver signal periods.

[0368] The electronic device equipped with the composite human interface may have a seventh composite function input button 1270.

[0369] The first receiver of the seventh multi-function input button may have the same scan signal period as the fourth receiver of the first multi-function input button and the second receiver of the fifth multi-function input button.

[0370] The second receiver of the seventh multi-function input button may have the same scan signal period as the first receiver of the third multi-function input button and the third receiver of the fifth multi-function input button.

[0371] The first transmitters of the first to third multi-function input buttons may have a first driver period, and the second transmitters of the first to third multi-function input buttons may have a second driver period.

[0373] The first transmitter of the fifth multi-function input button may have a fifth driver period, and the second transmitter of the fifth multi-function input button may have a sixth driver period.

[0374] The first transmitter of the sixth multi-function input button may have a seventh driver period, and the second transmitter of the sixth multi-function input button may have an eighth driver period.

[0375] At least two of the first to fifth multi-function input buttons may have the first to second receivers having the same scan signal period, and the third to fourth receivers having the same scan signal period.

[0376] At least two of the first to fifth multi-function input buttons may have the second to third receivers having the same scan signal period, and the first and fourth receivers may have different scan signal periods.

[0377] For example, the first to second receivers of the first multi-function input button may have a first scan signal period, and the third to fourth receivers may have a second scan signal period.

[0378] The first to second receivers of the third multi-function input button may have a third scan signal period, and the third to fourth receivers may have a fourth scan signal period.

[0379] The first receiver of the fourth multi-function input button may have a fifth scan signal period, the second to third receivers may have the first scan signal period, and the fourth receiver may have a second scan signal period.

[0380] The first receiver of the seventh multi-function input button may have a second scan signal period, the second to third receivers may have the third scan signal period, and the fourth receiver may have a fourth scan signal period.

[0381] FIG. 19 is an example of an electrode pattern for multiple multi-function input buttons, where the electrode portion may include two transmitters 1020c parallel to the X axis and four receivers 1020c parallel to the Y axis.

[0382] In the embodiments described below, an example is described in which two transmitters are parallel to the X axis and four receivers are parallel to the Y axis, but the same explanation can be applied to two receivers parallel to the X axis and four transmitters 1020d parallel to the Y axis.

[0383] The electronic device equipped with the composite human interface may be configured with first to fifth composite function input buttons, and each of the composite function input buttons may be configured with an electrode unit having a transmitter unit and a receiver unit.

[0384] The transmitter section may include first and second transmitters having different driver signal periods, and the receiver section may include first and second receivers having different scan signal periods.

[0385] The second receiver of the first multi-function input button may have the same scan signal period as the first receiver of the fifth multi-function input button, and the first receiver of the third multi-function input button may have the same scan signal period as the second receiver of the fifth multi-function input button.

[0386] The first transmitters of the first to third composite function input buttons may have a first driver signal period, the second transmitters of the first to third composite function input buttons may have a second driver signal period, the first transmitter of the fourth composite function input button may have a third driver signal period, the second transmitter of the fourth composite function input button may have a fourth driver signal period, the first transmitter of the fifth composite function input button may have a fifth driver signal period, and the second transmitter of the fifth composite function input button may have a sixth driver signal period.

[0387] The center points of the first to third multi-function input buttons may be on an imaginary X-axis line, the first to second transmitters of the first to fifth multi-function input buttons may be substantially parallel to the imaginary X-axis, and the first receiver and the second receiver of the first to fifth multi-function input buttons may be positioned substantially perpendicular to the imaginary X-axis.

[0388] The second receiver of the first multi-function input button and the first receiver of the fifth multi-function input button, and the second receiver of the fourth multi-function input button may have the same scan signal period.

[0389] Alternatively, the second receiver of the first multi-function input button and the first receiver of the fifth multi-function input button, and the first receiver of the seventh multi-function input button may have the same scan signal period.

[0390] The second receiver of the first composite function input button and the first receiver of the fifth composite function may be aligned in a row perpendicular to the X-axis and may be spaced a first distance 2010 between the second receiver of the fourth composite function input button and the first receiver of the seventh composite function input button.

[0391] This is necessary to unify the pattern in order to reduce the manufacturing cost of the multi-function input button. At this time, software correction of the user touch input is required.

[0392] The touch panel may further include a control unit that corrects the coordinates of the user's touch input in the X-axis direction in response to the first distance when the user's touch is successively input from the first multi-function input button to the fourth multi-function input button perpendicular to the X-axis.

[0393] The first to fifth composite function input buttons may include a control unit that senses successive user touches occurring within an area including the surfaces of the first to fifth composite function input buttons and continuously controls a single pointer position.

[0394] The first through fifth multi-function input buttons may each include a control section for sensing a user's pressure signal and generating a first through fifth character input signal, respectively.

[0395] That is, each of the multiple multi-function input buttons corresponds to one key of a keyboard, and generates one character. At the same time, in response to successive user touch inputs across the touch surface areas of the multiple adjacent multi-function input buttons, pointer position information such as a mouse pointer can be generated and the position movement of the pointer can be controlled.

[0396] When multiple touches are made simultaneously within the touch surface areas of the adjacent multiple function input buttons, multi-touch functions, such as zoom-in, zoom-out, scrolling, screen switching, etc., can be performed.

[0397] In the case of an electrode 1020h in which the receiver is parallel to the X-axis and the transmitter is parallel to the Y-axis, the electronic device equipped with the composite human interface device may be composed of first to fifth composite function input buttons, each of which is composed of an electrode portion composed of a transmitter portion and a receiver portion, the transmitter portion may have first to second transmitters having different driver signal periods, and the receiver portion may have first to second receivers having different scan signal periods.

[0398] The second transmitter of the first multi-function input button may have the same drive signal period as the first transmitter of the fifth multi-function input button, and the first transmitter of the third multi-function input button may have the same drive signal period as the second transmitter of the fifth multi-function input button.

[0399] The first receiver of the first to third composite function input buttons may have a first scan signal period, the second receiver of the first to third composite function input buttons may have a second scan signal period, the first receiver of the fourth composite function input button may have a third scan signal period, the second receiver of the fourth composite function input button may have a fourth scan signal period, the first receiver of the fifth composite function input button may have a fifth scan signal period, and the second receiver of the fifth composite function input button may have a sixth scan signal period.

[0400] The center points of the first to third multi-function input buttons may be on an imaginary X-axis line, the first to second receivers of the first to fifth multi-function input buttons may be substantially parallel to the imaginary X-axis, and the first to second transmitters of the first to fifth multi-function input buttons may be positioned substantially perpendicular to the imaginary X-axis.

[0401] The second transmitter of the first composite function input button and the first transmitter of the fifth composite function may be aligned in a row perpendicular to the X-axis and located between the second transmitter of the fourth composite function input button and the first transmitter of the seventh composite function input button.

[0402] FIG. 23 is a flowchart showing a method for switching between the text input mode and the pointer position information input mode.

[0403] The electronic device equipped with the composite human interface may be provided with a right-handed mode and a left-handed mode.

[0404] In the right-handed mode, touch areas may be configured to allow a user to easily input touch input from the user's right hand.

[0405] In the left-handed mode, touch areas may be configured to allow a user to easily input touch input from the user's left hand.

[0406] The right-handed mode and the left-handed mode may be set by a separate switch on an electronic device equipped with the composite human interface device, at least two simultaneous text inputs, a predefined touch pattern, a combination of text input and touch input, input via a mode switching unit, etc.

[0407] In the electronic device equipped with the composite human interface, the first pointer execution command button and the second pointer execution command button are operated by a user's pressure, and the first pointer execution command button and the second pointer execution command button further include a sensor that can detect a user's touch input, and when a touch input is received on the first pointer execution command button and the second pointer execution command button, the electronic device equipped with the composite human interface can be switched to a temporary touch mode.

[0408] The temporary touch mode may be cancelled and switched to a text input mode when the user releases his / her touch on the first pointer execution command button or the second pointer execution command button.

[0409] The first pointer execution command button may be located to the left of the second pointer execution command button and adjacent to the thumb of a user's left hand, and the second pointer execution command button may be provided adjacent to the thumb of a user's right hand.

[0410] When the temporary touch mode is switched to through a touch sensor provided in the first pointer execution command button, the electronic device having the composite human interface may be switched to a right-handed mode.

[0411] In the right-handed mode, the right-hand touch area 108b for receiving pointer position information can be set to facilitate touch input with the right hand.

[0412] The right hand touch area 108b can be set to exclude the area where the user's left hand rests to input text.

[0413] For example, in the case of a general keyboard-type composite human interface, the left side of the Y axis including the text F key is set as a touch inactive area, and the right side of the Y axis including the text G key is set as a touch active area.

[0414] When the temporary touch mode is switched to through a touch sensor provided in the second pointer execution command button, the electronic device having the composite human interface may be switched to a left-handed mode.

[0415] In the left-handed mode, the left-hand touch area 108a for receiving pointer position information can be set to facilitate touch input with the left hand.

[0416] The left hand touch area 108a can be set to exclude the area where the user's right hand rests to input text.

[0417] For example, in the case of a general keyboard-type composite human interface, the right side of the Y axis including the text J key is set as a touch inactive area, and the left side of the Y axis including the text H key is set as a touch active area.

[0418] In addition, a left-handed or right-handed mode can be preset in an external device connected to the electronic device having the composite human interface.

[0419] The temporary touch mode may be switched to the right hand touch mode when a user touch input occurs simultaneously from at least two of the plurality of multi-function input buttons generating text input signals of letters Q, W, E, and R in a US international keyboard layout, and may be switched to the text input mode by canceling the right hand touch mode when the at least two user touch inputs are released.

[0420] The temporary touch mode may be switched to the right hand touch mode when a user touch input occurs simultaneously from at least two of the plurality of multi-function input buttons generating text input signals of characters Z, X, C, and V in a US International keyboard layout, and may be switched to the text input mode by canceling the right hand touch mode when the at least two user touch inputs are released.

[0421] The temporary touch mode may be switched to the left hand touch mode when a user touch input occurs simultaneously from at least two of the plurality of multi-function input buttons generating text input signals of letters U, I, O, and P in a US International keyboard layout, and may be switched to the text input mode by canceling the left hand touch mode when the at least two user touch inputs are released.

[0423] The composite function input button on which the at least two touch inputs are generated simultaneously can function as a first pointer execution command input or a second pointer execution command input of a pointer controlled while executing the temporary touch mode when a pressure signal is further received while the touch input is maintained.

[0424] When the temporary touch mode is activated, the text input mode may be deactivated.

[0425] When the text input mode is inactive, there may be at least one exception such that text input is possible.

[0426] FIG. 24 is a flow chart of a permanent touch mode switching method.

[0427] When the first pointer execution command button and the second pointer execution command button are pressed simultaneously for a preset time, the electronic device including the composite human interface device may be set to a permanent touch mode.

[0428] The electronic device equipped with the composite human interface device may be set to a permanent touch mode by a separate switch on the electronic device equipped with the composite human interface, at least two simultaneous text inputs, a predefined touch pattern, a combination of text input and touch input, operation of a mode switching unit, etc.

[0429] The permanent touch mode is a mode in which a user can input pointer position information without having to maintain a separate user input to input the pointer position information.

[0430] As an example, in the temporary touch mode, an electronic device equipped with the composite human interface is basically set to a text input mode, and switches to the temporary touch mode while a separate user input is maintained, and when the separate user input is released, the temporary touch mode is released and the electronic device switches to the text input mode.

[0431] Meanwhile, in the permanent touch mode, the electronic device including the composite human interface is basically set to the permanent touch mode, and the text input mode may be deactivated.

[0432] The persistent touch mode can be cancelled under predefined conditions.

[0433] For example, if there is no touch input from the user for a predefined period of time while the permanent touch mode is set, the permanent touch mode may be cancelled.

[0434] When the permanent touch mode is set, if a predefined touch pattern, or a predefined button is input, or a text input button that is an exception to the inactivation is input, or text input is repeated, or multiple text inputs are input simultaneously, the permanent touch mode can be cancelled.

[0435] The permanent touch mode includes at least a part of the touch area in the right hand touch mode and the touch area in the left hand touch mode, and may be larger than the touch area in the right hand touch mode and the touch area in the left hand touch mode.

[0436] Preferably, the touch area may be a combined area of ​​the touch area in the right hand touch mode and the touch area in the left hand touch mode.
