Description

  The present invention relates to an input device, and more particularly to an input device having a touch panel.

  For example, in a mobile terminal such as a mobile phone, various input devices have been developed depending on the function and use of each terminal when a user operates the terminal. In many cases, an input operation is performed when a user directly presses a mechanical key or button or the like provided in advance on the surface of the mobile terminal body with a finger or the like.

  A mechanical key (such as a numeric keypad) of an input device in such a terminal is usually arranged in advance according to the main use of the terminal. The physical layout cannot be changed later.

  By the way, recently, a variety of functions have been incorporated into small portable terminals, as some mobile phones have digital cameras and music playback functions. Schedule management and address book with a single terminal such as a mobile phone that has many auxiliary functions in addition to the main use of the terminal, or a PDA (Personal Digital Assistant) Some have multiple main uses. In such a terminal, if the key arrangement is fixed, depending on the function used, it may be extremely inconvenient at the time of operation input.

  In order to eliminate such inconvenience at the time of operation input, an input device including a touch panel configured by placing a transparent input unit on a front surface of a liquid crystal display screen constituting the display unit is disclosed. (For example, refer to Patent Document 1). An input device having such a touch panel generally displays images (hereinafter referred to as “input objects”) such as operation keys and buttons on a display screen of the touch panel. When the user presses the input object displayed on the display screen, the input unit of the touch panel corresponding to the position receives the input.

  The foldable mobile phone described in Patent Document 1 can arbitrarily display an arrangement of input objects on a display screen of a touch panel to accept a user's operation input, and constitutes an arrangement of free keys and the like. It is possible. Therefore, each time the function of the terminal is switched, the mobile phone can provide extremely good operability by freely changing the arrangement of the input object according to the function. For example, when using a digital camera function mounted on a mobile phone, an input object constituting an operation unit for the digital camera can be displayed on the touch panel to accept an operation input. On the other hand, when inputting characters such as e-mails using this mobile phone, an input object constituting a keyboard such as a personal computer (PC) can be displayed on the touch panel to accept the input. As described above, by providing the touch panel, one input device can be optimized for each of a plurality of functions to receive an operation input.

  In addition, since an input device having a touch panel accepts input by an input method in which the user directly touches (touches) an input object displayed on the display unit with a fingertip or the like, the user can perform an extremely intuitive operation. it can. That is, the user performs an operation by directly touching the input object displayed on the screen with a fingertip or the like according to the guidance displayed on the screen of the touch panel. For this reason, the user can operate the terminal very easily by an intuitive operation according to the guidance displayed on the screen, and as a result, an effect of reducing erroneous operations can be expected.

  As described above, using a mobile terminal equipped with a touch panel, not only a normal mobile phone call and an operation input when creating an e-mail, but also viewing of content distributed through the Internet and browsing the web (browsing) ) Operation input can also be performed. Moreover, the input device having such a touch panel is disposed in, for example, an ATM (automatic depositing and paying machine) such as a bank or a ticket vending machine such as a station, and is used on a daily basis other than a portable terminal. . Further, in a store such as a fast food restaurant, when an employee processes a customer order, a business is performed using a terminal device including an input device having a touch panel as described above. By using a touch panel as the input device, mechanical operation buttons or keys such as a keyboard other than the touch panel are no longer essential elements. Therefore, since the area for placing mechanical operation buttons and the like on the terminal device main body is small, the terminal device itself can be reduced in size as a whole, and the location of the terminal device in various stores and stations can be reduced. The degree of freedom can also be increased.

  Further, if a touch panel is used as the input device, it is necessary to configure a display unit for displaying various information and an input unit for receiving a user's operation input as separate functional units, as in the conventional configuration of a device. Rather, the information display unit and the input unit can be configured on one screen. Therefore, for example, it is possible to display an array of input objects constituting keyboard keys on the touch panel to accept a user input, and to display the input result near the keyboard on the touch panel. In this way, the user can confirm the input operation and the input result by the input operation on one screen.

  As described above, the touch panel has such an input device because of the merit that the input unit and the display unit can be configured on the same screen and the operation input can be performed intuitively. The number of terminal devices is increasing.

  However, in an input device having a touch panel, there is also a peculiar problem that occurs because the input unit and the display unit are configured on the same screen to accept intuitive operation inputs. In other words, the touch panel can configure the display unit by freely arranging the input objects. However, since the entire surface of the input unit is usually flat, the boundary between the input object and the part other than the input object is defined. It is difficult for the user to make a determination by tactile sense. In addition, when performing input on the touch panel, the user directly touches the input unit with his / her finger or stylus, so the input object is hidden at the moment of pressing input, and the user may not be able to visually recognize the operation input. Many.

  Therefore, the user cannot determine whether or not his / her fingertip is touching the position where the input object is present based on the touch of the fingertip. is there. In other words, a position slightly different from the intended position is pressed, and a portion outside the input object to be input is pressed, or an input object adjacent to the input object to be input is pressed. There is a risk. When the input object to be input is pressed with a finger, the display of the input object is hidden, and thus there is a higher possibility that the intended input cannot be performed.

  In addition, when an input unintended by the user is received by the input device as described above, an operation unintended by the user may be started based on the input. In such a case, the user has to perform an additional operation to cancel (cancel) the unintended operation. Furthermore, when an important processing operation that has been started up to that point is terminated by the unintended operation, there is a possibility that recovery may not be possible. Therefore, it is desirable to reduce the possibility that an unintended operation is started based on an input unintended by the user.

  As a technique that can help to cope with such a situation, a means for detecting the pressing force of the input to the touch panel is provided, and a mechanism for changing the height of the touch panel surface according to the input position and pressing force of the user with respect to the touch panel is provided. An input device is disclosed (for example, see Patent Document 2).

JP 2006-31224 A Japanese Patent No. 4039344

  According to the input device described in Patent Literature 2, when a user inputs an input object displayed on the display unit of the touch panel, the position touched by the user is input by changing the height of the touch panel. It can be shown that it is an object. That is, for example, when the user touches the input object, the position touched by the user is the input object by making the height of the touch panel surface higher than when the user touches a part other than the input object. Indicates. Further, when it is recognized that the user has lightly touched the position corresponding to the input object on the touch panel, the input device enlarges the input object to make it easy to see (for example, Patent Document 2). (See FIGS. 7 and 10). By taking such various measures, the input device described in Patent Document 2 supports input in order to avoid a user's erroneous operation.

  According to this input device, the user can determine whether or not the input object is present at the position of the touch panel touched by his / her fingertip by the touch of the finger. Further, since the input object touched by the user can be enlarged and displayed, even if the user touches the input object with the fingertip, the portion hidden by the touch can be relatively reduced. Therefore, according to this input device, the possibility that an input unintended by the user is accepted can be reduced.

  However, when such a technique is applied to a small portable terminal such as a cellular phone, there are some disadvantages. That is, the mechanical mechanism that changes the height of the touch panel surface as described above requires a width that is considerably larger than the width of the change in the surface of the touch panel. This is because the mechanical drive device that changes the height of the touch panel requires a certain size and it is necessary to secure a space for changing the height of the entire touch panel. In recent mobile phone development, miniaturization as much as possible is required, and it is technically difficult to mount a mechanical mechanism that changes the height of the touch panel surface on the main body of the mobile phone. Is assumed.

  In addition, unlike small terminals such as bank ATMs and station ticket machines, small portable terminals such as mobile phones are subject to considerable restrictions on the size of the touch panel itself that also serves as a display unit. The display unit for display is inevitably small. On the other hand, since it is necessary to accept various user inputs to the touch panel, it is necessary to display a large number of various objects for input even in a small portable terminal. For this reason, when the user touches the input object, it is assumed that it is difficult for the portable terminal to display the input object in an enlarged manner.

  In addition, when a large number of input objects are displayed on the touch panel having a limited area, the height of the touch panel is changed as described above to determine whether the position touched by the user is the input object. It is also considered difficult to show in practice. In particular, when a large number of input objects of limited size are displayed side by side, there is little or no space between these input objects. Therefore, it is considered that it is very difficult for the user to recognize the edge portions (portions corresponding to the key edges) of these input objects by changing the height of the touch panel. Therefore, when a large number of small input objects are displayed next to each other on the touch panel of a small portable terminal such as a mobile phone, it is difficult to reduce the user's erroneous input by applying the technique of Patent Document 2. Is expected.

  In the case of a small portable terminal such as a mobile phone, not only a large number of input objects are displayed on a touch panel with a limited area, but also the user who performs the input performs an input while walking or performs other operations. However, there is also a special situation where input is sometimes performed. Thus, even when the user is not gazing, there is a demand for an input device that accepts input to a large number of input objects as intended by the user and supports the user's erroneous operation. .

  Accordingly, an object of the present invention made in view of such circumstances is to provide an input device that can reduce user's erroneous operations when receiving press inputs to a plurality of adjacent input objects, for example, in a touch panel mounted on a mobile terminal. It is to provide.

The invention of the input device according to claim 1 that achieves the above object is as follows:

The control unit performs control so that a load reference for receiving the pressing input to the input object is different from a load reference for receiving the pressing input to the input object adjacent to the input object. It is a feature.

The invention according to claim 2 is the input device according to claim 1,
A vibration unit for vibrating the input unit;
The control unit controls the vibration unit to be driven when a pressing load detected by the load detection unit satisfies a load standard.

The invention according to claim 3 is the input device according to claim 2,
The control unit drives the vibration unit again even when the pressing load detected by the load detecting unit does not satisfy the load standard after the pressing load detected by the load detecting unit satisfies the load standard. It controls to do.

The invention according to claim 4 is the input device according to any one of claims 1 to 3,
The control unit receives the input unit when the pressing load detected by the load detecting unit does not satisfy the load standard after the pressing load detected by the load detecting unit satisfies the load standard. It controls so that the press input with respect to the said input object which is present is decided.

  According to the input device of the present invention, a load reference for detecting a pressing load on the input unit of the touch panel and receiving a pressing input for a certain input object, and a pressing input for an input object adjacent to the input object are received. Different from the load standard. Therefore, even if a large number of input objects are displayed adjacent to each other on the input unit of the small touch panel, the user can distinguish and input each input object.

  Embodiments of the present invention will be described below with reference to the drawings. In the following embodiment, a mobile phone will be described as an example of a mobile terminal including the input device of the present invention. However, a mobile terminal to which the input device of the present invention can be applied is not limited to a mobile phone, and can be applied to any mobile terminal having a touch panel such as a PDA. The present invention is not limited to a portable terminal having a touch panel, and can be applied to any input terminal having a touch panel such as a bank ATM or a ticket machine at a station as described above.

  FIG. 1 is an external perspective view showing a schematic configuration of a mobile phone 10 including an input device according to an embodiment of the present invention. The cellular phone 10 is configured by drawing various information and shapes such as keys and buttons on a liquid crystal display (LCD) or an organic EL display as shown in a partially cutaway manner on the front surface of the terminal body. A display unit 32 for displaying is provided. Further, on the front surface of the display unit 32, an input unit 34 composed of a matrix switch or the like that accepts input by a user's finger or stylus pen is disposed. In the present embodiment, the touch panel 30 includes the display unit 32 and the input unit 34.

  In addition, the mobile phone 10 may include a short-distance wireless communication unit such as a digital camera function unit, a one-segment broadcasting tuner, an infrared communication function unit, and various interfaces, depending on the required functions. The details and description are omitted.

  FIG. 2 is a functional block diagram schematically showing the internal configuration of the mobile phone 10 according to the present embodiment. As shown in FIG. 2, the mobile phone 10 includes a control unit 20, a touch panel 30, a load detection unit 40, a vibration unit 50, a storage unit 60, a voice input unit 70, a voice output unit 80, and a key. And an input unit 90. The control unit 20 controls and manages the entire mobile terminal 10 including each functional block of the mobile terminal 10. As described above, the touch panel 30 is configured by arranging the input unit 34 that receives input from the user so as to overlap the front surface of the display unit 32. With such a configuration, the touch panel 30 receives an operation input from the user and displays various information such as an input result in accordance with each application program (hereinafter abbreviated as “application”).

  The input unit 34 of the touch panel 30 outputs a signal corresponding to the position where the input by the contact is detected by detecting the input by the contact (press) of the user's fingertip or stylus. The touch panel 30 is configured using a known device such as a resistance film method or a capacitance method. In addition to performing display corresponding to each application, the display unit 32 draws and displays a user interface including various keys and buttons that accept user operation input to the input unit 34 in a predetermined display area. In the present embodiment, in order to accept a user operation input to the input unit 34 of the touch panel 30 as described above, an image such as various keys and buttons displayed on the display unit 32 is referred to as an “input object”.

  The load detection unit 40 detects a pressing load on the touch panel 30 (or the input unit 34), and is configured using, for example, a strain gauge sensor. The vibration unit 50 vibrates the touch panel 30 and is configured using, for example, a piezoelectric element or an ultrasonic vibrator. The structural relationship between the load detection unit 40 and the vibration unit 50 and the touch panel 30 will be described later.

  The storage unit 60 stores various applications and various input information, and also functions as a work memory. The storage unit 60 also stores a plurality of templates including various input objects used according to each application.

  The voice input unit 70 converts a user voice or the like into an input signal and transmits the input signal to the control unit 20. The sound output unit 80 converts the sound signal transmitted from the control unit 20 into sound and outputs the sound. The key input unit 90 transmits a corresponding signal to the control unit 10 in response to an operation input by the user. The use and function of various keys constituting the key input unit 90 are defined according to the application to be used.

  In addition, the mobile phone 10 further provides functions as a normal mobile phone such as an antenna and a wireless communication unit for transmitting and receiving various information such as voice calls and e-mail data to and from the base station via the Internet or wireless communication. It also has various functional parts necessary for this. However, since these are not particularly different from those of known techniques, description thereof is omitted.

  Next, the structural relationship between the above-described load detection unit 40 and vibration unit 50 and the touch panel 30 will be described.

  3 is a diagram illustrating an example of a mounting structure of the touch panel 30, the load detection unit 40, and the vibration unit 50 of the mobile phone 10 illustrated in FIG. 3A is a cross-sectional view of a main part, and FIG. 3B is a plan view of the main part.

  A display unit 32 that displays various input objects on the touch panel 30 is housed and held in the housing 12. An input unit 34 is held on the display unit 32 via an insulator 36 made of an elastic member. In the input device according to the present embodiment, the display unit 32 and the input unit 34 are rectangular in plan view. In FIG. 3, the touch panel 30 is illustrated as a square shape, but may be rectangular according to the specifications of the mobile terminal on which the touch panel 30 is mounted. In addition, the input device holds the input unit 34 on the display unit 32 via insulators 36 arranged at four corners that are out of the display area A of the display unit 32 indicated by phantom lines in FIG. .

  Further, the housing 12 is provided with an upper cover 14 so as to cover the surface area of the input section 34 that is out of the display area of the display section 32, and is made of an elastic member between the upper cover 14 and the input section 34. An insulator 16 is provided.

  The input unit 34 has, for example, a transparent film on the front surface, that is, a surface that accepts operation input, and glass on the back surface. When the operation surface is pressed, a small amount of the transparent film on the surface corresponds to the pressing force. Use a structure that bends (distorts).

  Furthermore, the input device according to the present embodiment detects a pressing load (pressing force) applied to the input unit 34 in the vicinity of each side covered with the upper cover 14 on the transparent film on the surface of the input unit 34. Each strain gauge sensor is provided by bonding or the like. In addition, on the glass surface on the back surface of the input unit 34, a piezoelectric element or an ultrasonic vibrator for vibrating the input unit 34 is provided in the vicinity of two opposing sides by bonding or the like. That is, in the input device shown in FIG. 3, the load detection unit 40 shown in FIG. 2 is configured using four strain gauge sensors, and the vibration unit 50 is configured using two vibrators. In FIG. 3B, illustration of the casing 12, the upper cover 14, and the insulator 16 shown in FIG. 3A is omitted.

  The input device according to the present embodiment monitors the input detected by the input unit 34 and the pressure load detected by the load detection unit 40 in the control unit 20. The control unit 20 is a predetermined input when the pressure input detected by the input unit 34 is an input to the input object displayed on the display unit 32 and the pressure load detected by the load detection unit 40 receives the input. When the above criteria are satisfied, the input is accepted as a regular input. Hereinafter, such “reference for accepting input” is simply referred to as “load reference”. When the input load standard is satisfied, the control unit 20 causes the vibration unit 50 to vibrate and vibrates the pressing object such as the user's finger or the stylus pen pressing the input unit 34. Control to tell. In addition, the load detection part 40 detects a load from the average value of the output of four strain gauge sensors, for example. The vibrating unit 50 drives, for example, two ultrasonic transducers in phase. Due to the vibration of the vibration unit 50 that occurs when the load standard is satisfied, the user can recognize that the press input made by the user is properly received.

  Next, an input object load criterion according to the present embodiment will be described. FIG. 4 is a graph schematically illustrating an example of a temporal change in pressing load (pressing force) detected by the load detecting unit 40 when the user performs an operation input by an operation of pressing the input unit 34 of the touch panel 30. . Generally, when the user performs an operation (press input) of pressing the input unit 34 of the touch panel 30, the pressing force applied to the input unit 34 until the time when the user can determine that the input has been received after touching the input unit 34. (That is, an operation of pushing the input unit 34 is performed). Further, the user reduces the pressing force on the input unit 34 from the time when it is determined that the input has been accepted (that is, performs an operation of releasing a finger or the like from the input unit 34). Therefore, the load detected by the load detection unit 40 increases from the left to the right as time elapses as the time elapses, and decreases from the middle to the right as shown by the curve shown in FIG.

  Hereinafter, an initial setting that is a preparation for performing the load standard setting process for the input object according to the present embodiment will be described. In the present embodiment, as a premise for performing the load standard setting process for the input object, first, an input is made to the input unit 34 for performing normal operation input on the input object displayed on the display unit 32. A load reference P1 that determines that the load has been made is set in advance. At this time, the load reference value P <b> 1 is set based on a normal pressing force when the user performs a normal operation input on the display unit 32. Based on this setting, when the load detection unit 40 detects a pressing load exceeding P1 (A1) as a normal pressing force when the user performs a normal operation input, the control unit 20 displays on the display unit 32. It is determined that the displayed input object is pressed. In addition, when the load detecting unit 40 detects a pressing load that interrupts P1 (A2) with respect to the input object that has been pressed (after A1), the control unit 20 performs an operation input to the input object that is being pressed. Is determined to be completed (confirmed).

  In this way, by setting the load reference value P1, it is possible to prevent the user from deciding as an input only by lightly touching the input unit 34, thereby avoiding an input unintended by the user. it can.

  In addition, by setting the load reference value P1 in this way, when performing continuous hitting input in which the same position (the same input object) is continuously pressed a plurality of times on the input unit 34, the user performs one input. It is possible to input repeatedly without releasing the finger from the input unit 34 every time. That is, even if the user's finger is still touching the input unit 34, the user adjusts the strength of the finger pressing force so that the pressing force is continuously increased or decreased with respect to the load reference value P1. By performing the input, the input unit 34 can recognize the input as a continuous hit input. Since such an input method requires less strokes for moving the finger for the user, the user can input quickly and easily with fewer movements by becoming familiar with the input method.

  Next, in the present embodiment, the load reference value P <b> 2 is set based on a pressing force larger (stronger) than a normal pressing force when the user performs a normal operation input to the input unit 34. In the present embodiment, a pressure exceeding the load reference value P2 set in this way is received as an input to the input object adjacent to the input object whose load reference value is P1. For this reason, when the load detection unit 40 detects a pressing load exceeding the pressing force P2 (B1) larger than P1 for the input object adjacent to the input object having the load reference value P1, the control is performed. The unit 20 determines that the adjacent input object is pressed. In addition, when the load detection unit 40 detects a pressing load that interrupts P2 (B2) with respect to the adjacent input object that has been pressed (after B1), the control unit 20 determines that the input being pressed It is determined that the operation input for the object is completed (confirmed). That is, the control unit 20 receives a pressure input for the input object displayed adjacent to the input object rather than the load reference P1 for receiving the pressure input for the input object displayed on the display unit 32. Is controlled to be higher.

  Therefore, even if the user presses the input object adjacent to the input object having the load reference value P1 with a normal pressing force (not reaching P2) when performing a normal operation input, This press input is not accepted as an input to the adjacent input object. Only when the user presses with a pressing force exceeding P2 that is larger than the normal pressing force (P1) when performing a normal operation input, this pressing input is input to the adjacent input object displayed. As accepted.

  In the above description, as an example, the value of the load standard (P1, P2) is regarded as the “threshold value of the pressing load”, and “the load standard is satisfied” when the value of the load standard is “exceeded”. The aspect which determines with was demonstrated. Hereinafter, the case where the determination is made based on such an aspect will be described. However, the aspect that can be determined as “the load standard is satisfied” is not limited to this, and it can be assumed that a number of aspects are included. For example, it can also be determined that the load criterion is satisfied when the pressing load by the user's pressing input to the input object “reaches” the value of the load criterion. It can also be determined that the load criterion is satisfied when the pressing load indicating the value of the load criterion is “detected” by the load detection unit 40.

  Next, the operation of the vibration unit 50 according to the present embodiment will be described. The vibration unit 50 vibrates the input unit 34 under the control of the control unit 20. The vibration of the input unit 34 is transmitted to the fingertip or stylus of the user who performs the operation input, so that the user can recognize by touch that the input to the input unit 34 has been appropriately performed. When generating this vibration, the control unit 20 controls the vibration unit 50 to be driven when the pressing load detected by the load detection unit 40 satisfies the load standard.

  In the present embodiment, different vibrations are generated for each of the load standards P1 and P2 described above. That is, the control unit 20 generates a vibration corresponding to the load reference P1 for the input object whose load reference value is P1. Thereby, the user can recognize that the input by the pressing load P1 has been appropriately received for the input object. Further, the control unit 20 generates a vibration different from the case of P1 corresponding to the load reference P2 for the input object whose load reference value is P2. Thereby, the user can recognize that the input by the pressing load P2 has been appropriately received for the input object.

  For example, when the load detection unit 40 detects a pressing load exceeding P1 (A1) shown in FIG. 4 for the input object whose load reference value is P1, the control unit 20 displays the state shown in FIG. The vibration unit 50 generates vibration having a waveform as shown in FIG. Thereafter, when the load detection unit 40 detects a pressing load that is equal to or less than P1 (A2) illustrated in FIG. 4 with respect to the input object, the control unit 20 performs the operation as illustrated in FIG. Waveform vibration is generated in the vibration unit 50. Further, when the load detection unit 40 detects a pressing load exceeding P2 (B1) shown in FIG. 4 for the input object whose load reference value is P2, the control unit 20 performs the processing shown in FIG. The vibration unit 50 generates vibration having a waveform as shown in FIG. Thereafter, when the load detection unit 40 detects a pressing load that is equal to or less than P2 (B2) illustrated in FIG. 4 with respect to the input object, the control unit 20 is configured as illustrated in FIG. Waveform vibration is generated in the vibration unit 50.

  In the example of vibration shown in FIG. 5, a short vibration is generated for an input object having a low load reference value (P1), and an input object having a high load reference value (P2). Long vibrations are generated. Thereby, the user can confirm the input by weak (short) vibration for an input related to a weak (low) pressing load, and strong (long) to an input related to a strong (high) pressing load. ) Input can be confirmed by vibration.

  Next, the load standard setting process for the input object according to the present embodiment will be described with reference to the flowchart of FIG. In the input object load standard setting process according to the present embodiment, the control unit 20 receives a request (command) for starting an application for displaying a user interface configured by the input object on the display unit 32 of the touch panel 30. Start by. When receiving a command for starting an application for displaying the user interface, the control unit 20 reads a template corresponding to the above-described request from the templates of various user interfaces stored in the storage unit 60 (step S1).

  After reading the user interface template, the control unit 20 determines whether or not there are a plurality of input objects included in the template (step S2). When there are a plurality of input objects included in the template, the control unit 20 next determines whether or not the specification is such that adjacent input objects are arranged at a predetermined interval (step S3). . The predetermined interval will be described later. When there are a plurality of input objects included in the template and adjacent input objects are arranged at a predetermined interval, the control unit 20 has different load standards for receiving pressure inputs to these input objects ( The load reference of each input object is set so that P1 and P2) (step S4).

  When the setting of the load reference for each input object is completed in step S4, the control unit 20 displays each of these input objects on the display unit 32 and accepts an input from the user (step S5). If there are not a plurality of input objects in step S2, that is, if there is only one input object, a normal load standard (P1) is set for the input object (step S6), and then step S5. Migrate to Further, even when a plurality of input objects are arranged at a predetermined interval or more in step S3, after setting a normal load standard (P1) for these input objects (step S6), The process proceeds to step S5.

  With the above processing, when a plurality of input objects are arranged adjacent to each other, the load standards for receiving the pressure input to the respective input objects are arranged in different modes. The predetermined interval described above means that if the interval between the input objects is less than the predetermined interval, the user is likely to erroneously input and press an input object that is different from the intended input object. Is the interval to be set as Here, the interval set as the predetermined interval can be the distance between the end portions of the input objects, or can be the distance between the center portions of the input objects. it can. Hereinafter, the result of the above-described processing will be specifically described with respect to a typical embodiment.

  For example, as shown in FIG. 7A, a case where a user memo creation application is activated will be described. This application displays a character input object on substantially the lower half of the display unit 32 of the touch panel 30 and accepts a user input to the input unit 34. The user memo creating application displays the character input objects separated from each other by a predetermined distance or more. Therefore, in this example, since it is unlikely that the user erroneously inputs and presses an input object different from the intended input object, each of these character input objects has a normal load standard ( P1) is set. As in this example, using the numeric keypad corresponding to the kana characters, the characters are input one by one by changing the kana characters corresponding to each key to "Aiueo order" according to the number of key inputs. Since the method is conventionally known as a “multi-tap input method”, description thereof is omitted.

  When the user saves the memo in the storage unit 60 (memory) after completing the input of characters as shown in FIG. 7A, the “function” input object shown in the upper left of the display unit 32 of the touch panel 30 Is touched to bring up a so-called pull-down display as shown in FIG. The “function” pull-down display includes “Save” and “Delete” input objects. When these two input objects are arranged at a distance less than a predetermined distance from each other, the load reference setting process described above causes the “save” input object and the “delete” input object to be a load reference that receives a press input. Are arranged in a different manner. In this case, when one of the input objects adjacent to each other is related to an operation that cannot be recovered (important), like this “deleted” input object, for example, 3N A load reference value P2 is set to (Newton). Further, for example, a load reference value P1 of 1N is set to an input object adjacent to the input object whose load reference value is P2, such as the “save” input object.

  Thus, by arranging the input objects with different load standards, for example, the user intended to press the “save” object, but accidentally pressed the “delete” object. Can be dealt with in case. That is, an input by a normal pressing force (not exceeding P2) when a normal operation input is performed on the “deleted” object is not accepted. In order to perform an input on the “delete” object, the user intentionally operates with a pressing load exceeding a load reference value (P2) larger than the normal pressing force (P1) when performing a normal operation input. Input is required.

  Further, even when the touch panel 30 has a function of simultaneously receiving inputs for a plurality of input objects, the same measures as described above can be performed. That is, the user intends to press the “save” object, but erroneously (or the contact area of the finger pressing the input unit 34 protrudes) causes the “save” and “delete” input objects to be pressed. There is a risk of both pressing simultaneously. Even in such a case, an input by a normal pressing force (not exceeding P2) when a normal operation input is performed on the “deleted” object is not accepted. Contrary to the above-described case, a countermeasure when the user intends to press the “delete” object but accidentally presses the “save” object will be described later.

  As described above, in this embodiment, for an input object arranged adjacent to an input object that receives an input by a pressing load based on a normal operation input (exceeding P1), the normal operation input is performed. The load is set to be larger (exceeding P2) than the pressing load based thereon. An input with a pressing load that is larger (heavy) than a normal operation input is an input different from various input modes (for example, long press, double press such as double click, etc.) assumed as a normal input method. . Therefore, input by various input modes assumed as a normal input method is not accepted for an input object whose load reference is P2, and therefore an input that is erroneously performed by the user without intention is valid. Will not be accepted as input. That is, an input due to an erroneous operation not intended by the user is avoided.

  Note that when the input objects are arranged next to each other by the processing of the present embodiment, it is necessary to input the input object with the load reference value P2 with a stronger pressing force than during normal operation input. It is preferable to perform a display that suggests to the user. For example, an input object that needs to be input with a strong pressing force, such as an input object for a “delete” key shown in FIG. 7C, is displayed in a color different from that of the input object for other keys. 32. Thereby, it can be emphasized that the input objects of different colors are input objects whose load reference value is P2. Further, when such an input object is displayed on the display unit 32, for example, a character such as “Please touch the input of the“ delete ”key strongly” ”may be displayed at a predetermined position on the display unit 32. Good.

  Another embodiment will be described. The screen display by the user memo creation application shown in FIG. 8 is similar to that shown in FIG. 7 in the configuration of the character input object displayed on the display unit 32 of the touch panel 30, but the user input result (memo) is displayed. The area to do is larger. Therefore, the area where the character input object for accepting the user's pressing input is arranged is relatively small. In such a case, as shown in FIG. 8, the area of each input object is reduced, and the interval between the input objects is displayed narrowly. When the interval between the input objects is less than the predetermined interval, based on the load standard setting process for the input object according to the present embodiment, the control unit 20 uses the input objects adjacent to each other with the interval less than the predetermined interval. Set different load standards for.

  By the load reference setting process according to the present embodiment, for example, as shown in FIG. 8, input objects having different load references are alternately arranged. In the example shown in FIG. 8, the input object that needs to be input with a strong pressing force is displayed in a different color in order to indicate that the input object is arranged according to different load standards. That is, a dark color input object (having broken line hatching) indicates that a load standard (P2) larger than the load standard (P1) used for normal operation input is set. On the other hand, an input object having a normal color (outlined) indicates that a normal load standard (P1) is set.

  As a result of setting the load reference in this way, the input unit 34 of the touch panel 30 is adjacent to the input object for which the normal load reference (P1) is set, and is larger than the normal load reference (P1) ( P2) is set. That is, every other input object for which the normal load standard (P1) is set and every other input object for which the load standard (P2) larger than the normal load standard (P1) is set. . Therefore, even when a plurality of input objects are densely adjacent to each other, the user can distinguish and input these input objects.

  Next, with reference to the flowchart shown in FIG. 9, the input object pressing input receiving process performed after the input object is arranged by the input object load standard setting process described in FIG. 6 will be described. This process is started from the point of time when the user memo creation application or the like is activated and the input object is displayed side by side on the display unit 32 by the process described with reference to FIG.

  When the input object pressing input acceptance process according to the present embodiment is started, the control unit 20 receives an input by the user's fingertip, stylus, or the like (hereinafter abbreviated as “user input”) to the input unit 34 of the touch panel 30. It is determined whether or not it has been detected (step S12).

  When input by the user to the input unit 34 is detected in step S12, the control unit 20 in the display unit 32 corresponding to the position of the input unit 34 that has received the input based on the input from the input unit 34. The position is determined (step S13). Further, based on the determination result, the control unit 20 inputs the load reference (P2) in which the position of the display unit 32 corresponding to the position where the input is detected is set larger than the normal load reference (P1). It is determined whether the position corresponds to the object for use. When the input position is a position corresponding to the input object for which the load reference (P2) larger than the normal load reference (P1) is set (Yes in step S13), the control unit 20 selects the input object. A highlight is displayed (step S14).

  The highlight display in step S14 is highlighting performed to make the user recognize that the user's fingertip or the like is touching the input object. For example, when a user input to the input object of the “delete” button as shown in FIG. 10A is detected, the control unit 20 displays the input object as shown in FIG. Change to light display. Thereby, the user can visually recognize that the input of his / her fingertip touching the input unit 34 is properly detected. This highlight display only indicates that the user's fingertip or the like is touching the input unit 34, and at this point, it is determined that the input is still accepted (that is, the key is pressed). Not.

  Next, the control unit 20 determines whether or not the pressure load value P detected by the load detection unit 40 exceeds the load reference value P2 (step S15). If an input exceeding the load reference value P2 is not made to the input object for which the load reference P2 is set, the input object is not processed as being accepted. Therefore, in step S15, when the pressing load P having a value exceeding the load reference value P2 is not detected by the load detection unit 40, the control unit 20 determines whether or not the input by the user to the input unit 34 has been released. (Step S16).

  If the input is not canceled in step S16 (that is, the user has not removed the fingertip or the like from the input unit 34), the control unit 20 returns to step S15 and the value P of the pressing load detected by the load detection unit 40. To monitor. When the input by the user to the input unit 34 is canceled in step S16, the input object touched by the user is treated as being not input, and the highlight display is canceled (step S17). This process ends.

  The cancellation of the highlight display in step S17 is a display for indicating to the user that the input of the user's fingertip or the like touching the input unit 34 at the position corresponding to the input object is not detected. For example, as shown in FIG. 10B, the control unit 20 displays a highlight display of the input object that is displayed on the display unit 32 when a user input is detected, as shown in FIG. Return to display. Thereby, the user can visually recognize that his / her fingertip or the like touching the input unit 34 is separated from the input unit 34.

  On the other hand, when the pressing load P exceeding the load reference value P2 (B1 shown in FIG. 4) is detected by the load detection unit 40 in step S15, the control unit 20 determines that the pressing load P has the load reference value P2. The vibration unit 50 is vibrated in order to notify the user that it has been exceeded (step S18). In this case, the control unit 20 causes the vibration unit 50 to generate vibration having a waveform as shown in FIG. 5C (long vibration corresponding to a strong input). As a result, the user can identify that his or her pressing load P has exceeded the load reference value P2.

  Further, in step S18, the control unit 20 changes the display of the display unit 32 to indicate that the input object whose input has been detected is pressed as a key. That is, for example, the highlighted input object as shown in FIG. 10B is displayed as shown in FIG. 10C to indicate that the input object is pressed. . Thereby, the user can visually recognize that the pressing input by his / her fingertip or the like touching the input unit 34 is appropriately received as the pressing input with respect to the input object.

  After step S18, the control unit 20 reduces the pressing force input by the user to the input unit 34, and the pressing load P detected by the load detection unit 40 falls below the load reference value P2 (B2 shown in FIG. 4). It is determined whether or not (step S19). In step S19, when the pressing load P becomes equal to or less than the load reference value P2, the control unit 20 determines the operation input for the input object whose load reference is P2 while receiving the current input. (Step S20). That is, in the input process according to the present embodiment, when compared with a mechanical key, when the key is pressed, the acceptance of the key input is not yet confirmed, and the key is not pressed until the key is released. Confirm acceptance of input.

  Further, in step S20, the control unit 20 returns the display of the display unit 32 to the highlight display so as to indicate that the pressing load on the input object whose input has been detected is equal to or less than P2. That is, for example, the display indicating that the input object shown in FIG. 10C has been pressed is returned to the highlighted display of the input object as shown in FIG. 10B. Thereby, the user can visually recognize that the pressing input to the input object is confirmed as an input and that the pressing force pressing the input object is relaxed appropriately.

  Furthermore, in step S20, the control unit 20 vibrates the vibration unit 50 in order to indicate to the user that the operation input for the input object whose load reference is P2 is confirmed. At this time, the control unit 20 causes the vibration unit 50 to generate a vibration having a waveform as shown in FIG. 5D (long vibration corresponding to a strong input). Thereby, the user can identify that the operation input with respect to the input object whose load reference is P2 is confirmed.

  After step S20, the control unit 20 determines whether or not the input by the user to the input unit 34 has been canceled (step S21). If the input is not canceled in step S21 (that is, the user has not removed the fingertip or the like from the input unit 34), the control unit 20 continues to monitor the pressing load P detected by the load detection unit 40. If the input by the user to the input unit 34 is canceled in step S21, the process proceeds to step S17 described above to cancel the highlight display, and this process ends.

  In addition, when a series of processes from Step S15 to Step S18 as described above to Step S19 and Step 20 are performed, an example of a pressing load on the input unit 34 detected by the load detection unit 40 is as follows: A curve β shown in FIG. 11 is obtained.

  On the other hand, when the input position is not a position corresponding to the input object for which the load reference P2 is set in step S13, the control unit 20 proceeds to step S22 and highlights the input object. . In addition, the case where it transfers to step S22 from step S13 is a case where the input object by which the input by the user was detected is an input object to which the load reference | standard P1 was set. The highlight display of the input object performed in this case is also performed in the same manner as described in step S14.

  Next, the control unit 20 determines whether or not the pressure load value P detected by the load detection unit 40 exceeds the load reference value P1 (step S23). As in the case of performing normal operation input, if an input exceeding the load reference value P1 is input to the input object for which the load reference P1 is set, the input object is processed. Therefore, when the pressing load P with a value exceeding the load reference value P1 is not detected by the load detection unit 40 in step S23, it is determined whether or not the input by the user to the input unit 34 has been released (step S24).

  If the input is not canceled in step S24 (that is, the user has not removed the fingertip or the like from the input unit 34), the control unit 20 returns to step S23 and the value P of the pressing load detected by the load detection unit 40. To monitor. If the input by the user to the input unit 34 is canceled in step S24, the input object touched by the user is treated as not input, and the highlight display is canceled (step S17). This process ends.

  On the other hand, when the pressing load P exceeding the load reference value P1 (A1 shown in FIG. 4) is detected by the load detection unit 40 in step S23, the control unit 20 determines that the pressing load P has the load reference value P1. The vibration unit 50 is vibrated in order to notify the user that it has been exceeded (step S25). In this case, the control unit 20 causes the vibration unit 50 to generate a vibration having a waveform as shown in FIG. 5A (short vibration corresponding to a weak (normal) input). Thereby, the user can identify that the pressing load P has exceeded the load reference value P1.

  Further, in step S25, the control unit 20 changes the display of the display unit 32 to indicate that the input object whose input has been detected has been pressed. That is, for example, the highlighted input object as shown in FIG. 10B is displayed as shown in FIG. 10C to indicate that the input object is pressed. . Thereby, the user can visually recognize that the pressing input by his / her fingertip or the like touching the input unit 34 is appropriately received as the pressing input with respect to the input object.

  After step S25, the control unit 20 reduces the pressing force input by the user to the input unit 34, and the pressing load P detected by the load detection unit 40 is below the load reference value P1 (A2 shown in FIG. 4). It is determined whether or not (step S26). When the pressing load P becomes equal to or less than the load reference value P1 in step S26, the control unit 20 determines the operation input for the input object whose load reference is P1 while currently receiving the input. (Step S27).

  In step S27, the control unit 20 returns the display of the display unit 32 to the highlight display so as to indicate that the pressing load on the input object whose input is detected is equal to or less than P1. That is, for example, the display indicating that the input object as shown in FIG. 10C is pressed is returned to the highlighted display of the input object as shown in FIG. 10B. . Thereby, the user can visually recognize that the pressing input to the input object is confirmed as an input and that the pressing force pressing the input object is relaxed appropriately.

  Further, in step S27, the control unit 20 vibrates the vibration unit 50 in order to indicate to the user that the operation input for the input object whose load reference is P1 is confirmed. At this time, the control unit 20 causes the vibration unit 50 to generate a vibration having a waveform as shown in FIG. 5B (short vibration corresponding to a weak (normal) input). Thereby, the user can identify that the operation input with respect to the input object whose load reference is P1 is confirmed.

  After step S27, the control unit 20 determines whether or not the input by the user to the input unit 34 has been canceled (step S21). If the input is not canceled in step S21 (that is, the user has not removed the fingertip or the like from the input unit 34), the control unit 20 continues to monitor the pressing load P detected by the load detection unit 40. If the input by the user to the input unit 34 is canceled in step S21, the process proceeds to step S17 described above to cancel the highlight display, and this process ends.

  As described above, when a series of processing from step S23 to step S25 to step S26 and step 27 is performed, the pressing load on the input unit 34 detected by the load detection unit 40 is exemplified. The curve is as shown in FIG.

  On the other hand, if the pressing load P is not less than or equal to the load reference value P1 in step S26, the control unit 20 determines whether a so-called slide input in which the position of the pressing input detected by the input unit 34 changes is detected. Is determined (step S28). The slide input here means that the input position changes from the input object originally pressed to another input object by moving the finger or the like while the user presses the input unit 34 with the finger or the like. Indicates the input to be performed.

  If such a slide input is not detected by the input unit 34 in step S28, the control unit 20 returns to step S26 and continues to monitor the pressure load value P detected by the load detection unit 40. However, in step S28, when the slide input with the pressing load exceeding P1 is detected for the input unit 34, the control unit 20 proceeds to step S13 and continues the process. When the process proceeds from step S28 to step S13, the process proceeds after canceling the press display of the input object for which the press input was originally detected (before the slide input was performed).

  In step S13 after the slide input (step S28), if the destination whose input position has changed by the slide input is an input object with a low load reference (P1), the process flow goes from step S22 to step S23 to step S25. Continue to. That is, since the input pressing load P for the input object with the load reference P1 exceeds the load reference value P1, the input is not yet accepted (not determined), and until the input is determined. The object for input can be changed by slide input. When the input object is changed by slide input and the load reference of the pressure input is less than or equal to P1 with respect to the input object with the load reference P1, the input object with the load reference being pressed at that time is P1 The input to is confirmed.

  On the other hand, in step S13 after the slide input (step S28), when the input position changed by the slide input is an input object with a high load reference (P2), the process proceeds to step S14, and the control unit 20 Highlight the input object. Here, if the pressing load of the slide input performed while exceeding the pressing load P1 does not exceed P2, the input to the input object with the higher load reference (P2) whose input position has changed is still the pressing input. Not accepted as. That is, by performing the slide input to the input object of the load reference P2 while keeping the initial pressing input (P1 <P <P2) detected for the input object of the load reference P1 in an uncertain state. The input can be changed to an input object having a different pressing load.

  Accordingly, thereafter, in step S15, the control unit 20 determines whether or not the value P of the pressing load detected by the load detection unit 40 exceeds the load reference value P2. In step S15, when the pressing load P exceeding the load reference value P2 is detected by the load detection unit 40, the control unit 20 treats the input object as being pressed. Furthermore, when the pressing load P becomes equal to or less than the load reference value P2 in step S19, the control unit 20 sets the operation input for the input object currently being accepted as a confirmed input. Accept.

  As described above, the process of accepting the slide input in step 28 can cope with a case where a user who intends to press the load reference P2 input object accidentally presses the load reference P1 object. . That is, by this process, for example, in the example shown in FIG. 7, the user intended to press the “deleted” object (load reference P2 (high)), but mistakenly the “saved” object (load reference P1 ( It is possible to deal with the case where the low)) is pressed. The processing and operation in such a case will be specifically described below.

  At first, when the object of the load reference P1 is accidentally pressed (Yes in step S23) while the user intends to press the input object of the load reference P2, the user returns a long vibration corresponding to the load reference P2. I expect it to come. However, actually, a short vibration corresponding to the load reference P1 is generated (step S25). By this vibration, the user can recognize that his / her own pressing input is not properly input to the input object of the load standard P2 and has touched the input object of the load standard P1. However, at this time, the acceptance of the operation input for the input object (load reference P1) being pressed by the user has not yet been confirmed (the confirmation process is performed in step S27).

  A user who recognizes that the object of the load reference P1 is accidentally pressed by this vibration, presses the input unit 34 to the originally intended object of the load reference P2 while maintaining the pressing load exceeding the load reference P1. A finger or the like can be slid (step S28). When a slide input is performed from the load reference P1 object to the originally intended load reference P2 input object (step S13), the destination load reference P2 input object is highlighted (step S14). It has not been pressed yet.

  Therefore, when a pressing input of a pressing load exceeding P2 is performed by the user (step S15), the pressing input is accepted with respect to the input object of the load reference P2 originally intended (step S18). The operation by the user at this time corresponds to an operation of strongly pressing the input object after sliding input to the originally intended input object. Thereafter, the user presses the pressing load or performs an operation such as releasing the finger from the input unit 34 (step S19), thereby confirming the pressing input to the input object of the originally intended load reference P2 ( Step S20).

  When the series of processes before and after the slide input as described above is performed, the pressure load applied to the input unit 34 detected by the load detection unit 40 is illustrated as a curve γ shown in FIG. In the curve γ, when the user intends to press the input object of the load reference P2, but accidentally presses the object of the load reference P1, this corresponds to A1, and the corresponding operation is changed from step S13 to step S22. Become. In A1, a period (step S28) in which a user who has noticed a pressing error due to occurrence of vibration different from the intention performs slide input corresponds to a flat portion between A1 and B1. Furthermore, after the user performs a slide input to the input object originally intended, the time when the input object is strongly pressed corresponds to B1, and the corresponding operation is from step S15 to step S18. After that, the user passes the B2 by the operation of weakening the pressing force and trying to release the finger from the input unit 34, and the operation corresponding to this passes from Step S19 to Step S20.

  As described above, in the present embodiment, the user intends to press the object of the load reference P2 by the input input pressing process of the input object, but the user presses the object of the load reference P1 by mistake. Can also deal with cases.

  In addition, this invention is not limited only to embodiment mentioned above, Many change or deformation | transformation is possible. For example, in the above-described embodiment, it is assumed that the load reference values P1 and P2 of the input object and the predetermined interval are set in advance, but the user can appropriately change or adjust as necessary. It is desirable to make it. In this way, if the user feels uncomfortable about the setting of the pressing load during the operation, the setting can be appropriately corrected later.

  Further, in the above-described embodiment, when the pressing load input by the user exceeds P1 or P2, the vibration unit 50 is vibrated so that the user can recognize that. The vibration generated by the vibration unit 50 is not limited to the vibration mode based on the waveform shown in FIG. 5, and can be distinguished whether the input pressing load by the user exceeds P1 or P2. Any vibration can be used. In such a case, it is not an essential requirement to generate a vibration. For example, a specific sound can be generated from the audio output unit 80 in addition to the vibration. Further, by changing the color or display mode of the input object that receives the input on the display unit 32, it may be indicated that the pressing load of the input by the user exceeds P1 or P2.

  In the above-described embodiment, when the interval between the input objects is less than the predetermined interval, the load standard of each input object is made different in order to prevent a user's erroneous operation. However, even if there is no interval between the input objects and they are adjacent to each other, if the input reception range of each input object is wide, the possibility that the user will make an input error is low. Therefore, in such a case, as long as the input reception range of each input object is equal to or larger than a predetermined area, it is not necessary to make the load standards different. Also, if the input acceptance range of each input object is wide, the input object input acceptance is set at a predetermined interval as a reference for determining whether or not the load reference is different based on the fact that the user is less likely to make an input error. It may be varied depending on the range. That is, even if 1 cm is set as the predetermined interval, if the input reception range of the input object is wide, the load standard is not different unless the input object interval is less than 0.1 cm, and the input object When the input reception range is narrow, the load standard may be different when the interval between the input objects is less than 2 cm.

  In the above-described embodiment, the case where the load standards are P1 and P2 has been described as the simplest example, but three or more load standards may be used as necessary.
