Description

  The present invention relates to a mobile terminal, and more particularly to a mobile terminal that includes a touch panel and inputs information by touching the touch panel.

Today, many portable terminals such as mobile phones, smart phones, and tablet terminals use touch panels as input means for inputting information and selecting functions.
The touch panel is configured to overlap with a display screen such as an LCD. For example, a keyboard layout is displayed on the display screen, and a character or the like is input by touching a display area portion of a desired key.
Therefore, it is not necessary to provide a hard key like a conventional keyboard, and an input interface can be provided using the same area as the display screen, so that the apparatus can be reduced in size and weight.

However, in general, an input interface using a touch panel has a problem that an erroneous operation is likely to occur when the user unintentionally touches the display screen.
Therefore, an apparatus that can prevent such an erroneous operation has been proposed.

  For example, in Patent Document 1, a normal display mode, a touch input mode, and a handwriting mode are switched by a mode change switch, and mainly in the case of the handwriting mode, an input invalid area is set around the frame periphery of the touch screen. A handwriting input device is described in which when the input invalid area is inadvertently touched, the input is invalidated to prevent an erroneous operation.

JP 2000-39964 A

  In a mobile terminal equipped with a touch panel, there are many scenes in which it is operated while being held in a hand, and there is a high possibility that a finger holding the terminal touches the touch panel to cause an erroneous operation. Such an erroneous operation may occur even in a touch input mode other than when performing handwriting input.

Therefore, in order to prevent an erroneous operation, it is preferable to provide an input invalid area in the peripheral portion of the touch panel frame not only when handwritten input but also when a function selection screen is displayed.
However, when the input invalid area is provided, the effective area where contact input can be performed becomes substantially narrow, so that the entire display screen cannot be used effectively.
Further, in order to prevent erroneous input by a finger holding the terminal, it is always necessary to provide an input invalid area around the touch panel and the frame of the display screen, but the effective area where contact input is possible becomes narrower. At the same time, since the effective area of the display screen is also narrowed, there is a possibility that the merit of increasing the screen size may be lost.

In addition, it is possible to place the terminal on the palm of one hand and input with the finger of the other hand on a terminal with a small housing size, or to hold it with the thumb and other fingers sandwiched between them. Can be held.
However, some terminals with a large housing size are difficult to hold by holding both sides of the terminal with one hand, so to avoid touching the touch panel, pinch the side edge of the terminal with one hand. Will have so.

In this case, if not firmly held, stability is lost and there is a risk of dropping.
In addition, it is quite difficult to hold the touch panel so that it does not touch the periphery of the touch panel close to the edge of the casing. Therefore, when the terminal is held for a long time, the arm tends to get tired.

Furthermore, in today's portable terminals, in order to increase the screen size, reduce the weight, improve the design, and the like, the number of narrow frame type terminals with a small frame frame around the display screen is increasing.
Therefore, it is necessary to pay close attention so that fingers with the side of the terminal do not accidentally touch the touch panel, but as the frame becomes narrower, it becomes increasingly difficult to hold the terminal so that it does not touch the touch panel. .

  Therefore, the present invention has been made in consideration of the above circumstances, and by adjusting the display area and the area where contact input is possible according to the use situation of the user, it is possible to prevent erroneous input. It is an object of the present invention to provide a portable terminal capable of stably holding a terminal.

The present invention includes a display unit that displays display data, a touch panel that is arranged on the display unit, a holding state setting unit that sets whether or not the usage pattern is a holding state to be held in hand, Based on the usage pattern set by the holding status setting section, based on the usage pattern set by the holding status setting section, the display adjustment section for adjusting the display area of the display data to be displayed on the display section based on the usage pattern set by the holding status setting section. A touch area adjustment unit that adjusts an input effective area that determines that touch input to the touch panel is valid, and a touched position of the touch panel are detected, and it is determined whether or not the detected touch position is within the input valid area A contact input determination unit; and a control unit that executes a predetermined function corresponding to the contact position when the contact position of the touch panel is determined to be within the input effective area; There is provided a portable terminal, characterized in that it comprises.
According to this, since the function is executed when the touch position of the touch panel is within the input effective area, the input effective area is set to an area other than the area where the user may hold the input effective area. This prevents input errors.

According to the present invention, the input effective area and the display area are adjusted based on the usage pattern, and when it is determined that the touch position of the touch panel is within the input effective area, a predetermined function is executed. Even if the touch panel area other than the input valid area is touched, the function is not executed and erroneous input can be prevented.
In addition, since the input effective area is set in the display screen other than the peripheral part having a predetermined width, it is possible to prevent erroneous input more reliably and hold the mobile terminal more stably. Can prevent the risk of falling and reduce hand fatigue during operation.

It is a block diagram of the configuration of an embodiment of the portable terminal of the present invention. It is explanatory drawing of one Example of the display screen of a normal mode. It is explanatory drawing of one Example of the display screen of hold mode. It is explanatory drawing of one Example of the display screen of hold mode. It is a flowchart of the adjustment process of the display area and input effective area of this invention.

Further, in the portable terminal of the present invention, the usage mode set by the holding state setting unit is either a hold mode that means a holding state that is held by hand or a normal mode that means a non-holding state. When the usage pattern is set to the hold mode, the display adjustment unit reduces the display area so that the display data is displayed on a part of the display screen of the display unit, and the touch area The adjustment unit sets an area of the touch panel that overlaps the reduced display area as an input effective area.
According to this, since the display area and the input effective area set so as to overlap with the display area are reduced, when the user holds the portable terminal in his / her hand, the display area and the input effective area are reduced. By setting to a portion that is not touched by the user's hand, erroneous input can be prevented.

A storage unit that stores in advance the setting ratio of the reduction ratio of the display area on which the display data is displayed and the display position of the reduced display area on the display screen of the display unit; When the form is set to the hold mode, the display adjustment unit adjusts the display area based on the reduction ratio and the display position stored in the storage unit.
According to this, the display area is adjusted based on the reduction ratio and the display position stored in advance in the storage unit, so that the user can change the setting of the reduction ratio and the display position to support the user's holding method. Thus, erroneous input can be prevented more reliably.

The input valid area is set to a display screen other than a peripheral portion having a predetermined width in the display screen of the display unit.
Further, the peripheral portion that is not set in the input valid area is a portion of a display screen that may be touched by the user's hand when held by the user's hand.
According to this, the input effective area is set in the display screen of the display unit other than the peripheral part having a predetermined width, or the user's hand comes into contact when the user holds the portable terminal in his / her hand. Since a part of the display screen with high possibility is not set in the input valid area, it is possible to prevent erroneous input more reliably, and to hold the mobile terminal more stably, reducing the risk of falling. It can prevent and reduce hand fatigue during operation.

In addition, the holding state setting unit is configured to set the usage pattern in advance to either the holding state or the non-holding state by a user operation, and the user holds or tries to hold It is provided with at least one of the approach detection part which detects that a user's hand approached, and the approach detection part detected that a user held or the user's hand approached within a predetermined distance In this case, the usage pattern is set to a holding state.
According to this, the holding state and the non-holding state can be clearly set by using either the switching setting unit or the approach detection unit.

  The touch panel area other than the input valid area is an input invalid area that determines that no touch input is made even if a touch input is made.

Hereinafter, the present invention will be described based on the embodiments shown in the drawings.
However, this does not limit the present invention.

<Configuration of mobile terminal>
FIG. 1 shows a configuration block diagram of an embodiment of a portable terminal of the present invention.
1, the portable terminal of the present invention mainly includes a control unit 1, a display unit 2, an input unit 3, a switching setting unit 4, an approach detection unit 5, a display adjustment unit 6, a touch area adjustment unit 7, and a touch input determination unit. 8 and a storage unit 11.

Here, the switching setting unit 4 and the approach detection unit 5 correspond to a holding state setting unit that sets whether or not the usage pattern of the terminal is a holding state in which the terminal is used.
In the present invention, the display adjustment unit 6 adjusts the display area displayed on the display unit 2 based on the usage pattern set by the holding state setting unit, and the touch region adjustment unit 7 enables the touch input to the input unit 3. It is characterized by adjusting the input effective area to be determined.

The control unit 1 is a part that controls the operation of each functional block of the portable terminal (hereinafter also simply referred to as a terminal) of the present invention, and is a microcomputer mainly composed of a CPU, ROM, RAM, I / O controller, timer, and the like. It is realized by.
Further, based on the control program stored in the ROM or the like, the CPU organically operates various kinds of hardware, so that the display adjustment function, touch area adjustment function, display function, input function, etc. of the portable terminal of the present invention Is realized.

The display unit 2 is a part that displays display data including characters, figures, images, and the like. For a small and light portable terminal, for example, an LCD, an organic EL display, or the like is used.
When displaying an image or the like, display data for one screen to be displayed on the entire display screen is generated, and the display data is usually displayed on the entire display screen by giving the display data to a display controller (not shown).
A usage mode in which the generated display data is displayed on the entire display screen is referred to as a normal mode (or a first display mode). The normal mode corresponds to a mode that means a non-holding state in which the terminal is not held and operated.

In addition, according to the present invention, when the terminal end of the terminal is held by hand, even if contact input is made on the touch panel, it is determined that there is no contact input (invalid) (touch non-responsive region or input invalid) A non-display area is set by overlapping the input invalid area, and a reduced display mode is provided so that the generated display data is not displayed in the non-display area.
A usage mode in which an input invalid area is provided in this manner and reduced display is referred to as a hold mode (hand-held mode or second display mode). The hold mode corresponds to a mode that means a holding state in which the terminal is held and operated.

FIG. 2 shows an example of the display screen in the normal mode.
Here, as an example of the display screen, a case where display data related to the telephone function is displayed on the entire display screen of the display unit 2 is shown.
FIG. 3 shows an example of the hold mode display screen.
Here, a case is shown in which the display data relating to the telephone function is reduced and displayed at substantially the center of the display screen of the display unit. A non-display area that coincides with the non-touch area 23 is provided in the peripheral portion of the display screen near the frame 22 that forms the terminal casing.

The input unit 3 is a part for inputting information and selecting and inputting a function. In the present invention, a touch panel placed on the display unit 2 is used.
However, in addition to the touch panel, input means such as a keyboard and a mouse may be provided.
When using a touch panel, it may be arranged so as to overlap the entire display screen of the display unit 2, or the input unit and the display unit may be integrally formed.

In the normal mode in which the display data is displayed on the entire display screen, the entire touch panel is a touch reaction area (or referred to as an input effective area).
That is, regardless of the position on the touch panel, the contact input is determined to be valid, and a predetermined function corresponding to the contact input position is executed.
In other words, in the normal mode, the touch non-responsive area is not provided, and the entire touch panel is the touch reactive area, and the touch input to the touch panel is the input intended by the user regardless of the position of the touched touch panel. Regardless of whether the input is incorrect or incorrect, all are accepted as valid inputs.

On the other hand, in the case of the hold mode, a display in which the touch non-reactive area 23 is provided in the vicinity of the frame frame 22 and in the peripheral portion having a predetermined width in the display screen of the display unit, and the display data is displayed in a reduced size. A touch reaction area (input effective area) is set so as to overlap the area.
That is, the input effective area is set to a display screen other than the peripheral portion having a predetermined width in the display screen of the display unit, for example, as shown in FIG.
Further, when the touch response area of the touch panel is touched, the touch input is accepted as a valid input. However, when the touch input area is touched, the touch input is invalidated.

In addition, as described above, in order to make it easy to understand the area where touch input is possible, the non-touch area corresponds to the non-display area where display data is not displayed, and the touch response area matches the display area where display data is displayed. It is preferable to set so as to.
Therefore, in the hold mode, even if contact input is mistakenly performed in the non-display area, the contact input is invalidated, and erroneous input can be prevented.
The touch non-reactive region 23 is preferably provided in a part of the display screen that may be touched by the user's hand when the terminal is held by the user's hand. For example, as shown in FIG. You may provide in the peripheral part of the display screen of 22 vicinity.

FIG. 4 shows another embodiment of the hold mode display screen.
Here, the non-display area and the touch are not displayed on the display screen in the vicinity of the two opposite frame frames 22 held by the user's hand, but on all the display screens in the vicinity of the four frame frames 22 forming the casing. A non-reactive region 23 is provided.
In addition to this, for example, an identification display indicating a holding permission area allowing contact with a finger is performed on a part of the display area, a touch non-reactive area 23 is set to overlap the holding permission area, and the user performs an identification display. The holding permission area may be held. As the holding permission region corresponding to the touch non-reactive region 23, a rectangular region having a relatively large area as shown in FIG. 3 or FIG. 4 may not be set. You may set the circular area | region with the magnitude | size which will touch. In this case, the non-display area and the non-touch area do not have to match.

The switching setting unit 4 is a part that switches between the two modes described above, and is a part that presets the usage pattern to either the holding state or the non-holding state.
For example, a physical change-over switch provided at the end of the housing is used. The change-over switch may be a slide switch or a push button switch whose mode is changed each time the switch is pressed.

For example, when the changeover switch is set to the “normal mode”, the full screen display as shown in FIG. 2 is performed as described above, and the entire touch panel becomes the touch reaction area.
On the other hand, when the changeover switch is set to the “hold mode”, the reduced display as shown in FIG. 3 is performed, and the non-display area and the non-touch area are set.
The changeover switch 4 needs to be changed by the user himself / herself according to the intention of the user.

The approach detection unit 5 is a part that detects when the user tries to hold the terminal, that the user holds the terminal, or that the user's hand trying to hold approaches the frame frame 22 of the terminal. is there.
As the approach detection part 5, sensors, such as an infrared sensor, a piezoelectric sensor, an ultrasonic sensor, an optical sensor, can be used, for example.
These sensors may be provided, for example, at the portions 221 and 222 shown in FIG.
When it is detected by the approach detection unit 5 that the user has held the terminal or the user's hand has approached within a predetermined distance, the usage pattern is set to the holding state. That is, the mode is automatically switched from the normal mode to the hold mode.
On the other hand, when it is detected that the hand has been released or contact has been lost, the mode is automatically switched from the hold mode to the normal mode.

  When the proximity detection unit 5 is provided, it is not necessary for the user to intentionally switch the mode, and the mode can be changed simply by holding the terminal by hand or by placing the terminal on the desk. It can be switched automatically.

In FIG. 1, as a means for switching between two modes of use, a switch setting unit 4 and an approach detection unit 5 are shown, but it is not necessary to provide both of these means, and at least one of them is not provided. You may make it provide.
Moreover, when both means are provided, it may be set so that only the switching setting unit 4 is enabled according to the use situation of the user, or the approach detection unit 5 is also enabled. The user may be able to make initial settings.

The display adjustment unit 6 is a part that adjusts the size (display size) of the display area of the display data displayed on the display unit based on the usage pattern.
For example, when the usage mode is set to the normal mode, the display size is set so that the display data is displayed on the entire display screen as shown in FIG.
When the usage mode is set to the hold mode, the display area is reduced so that the display data is displayed on a part of the display screen of the display unit. For example, the display size is set so that the display data is reduced and displayed as shown in FIG.
When the display area is adjusted by reducing the display data, the size and the display position of the display area may be set based on the reduction ratio and the display position stored in advance in the storage unit 11.
However, an arbitrary reduction ratio may be set by the user.

Further, it may be possible to set whether the image is reduced with the same aspect ratio as that of a normal display screen as shown in FIG. 3, or whether the vertical and horizontal reduction ratios are different as shown in FIG.
Also, the display position of the reduced display area may be set by the user as to whether the display is to be the central display as shown in FIG. 3 or to be displayed at another position.

The touch area adjustment unit 7 is a part that adjusts an input effective area that determines that the touch input to the touch panel is valid based on the usage pattern.
It is preferable that the input effective area is adjusted in conjunction with the change of the display area, and a touch panel area having the same area as the display area and overlapping the display area is set as the input effective area.
For example, in the normal mode, the entire touch panel corresponding to the entire display screen is set as the input effective area, and no touch non-responsive area is created.

When the hold mode is set, the area of the touch panel that overlaps the display area of the reduced display data is set as the input effective area, and the portion corresponding to the non-display area is set as the non-touch area.
However, in addition to the reduction rate of the display data, the user may be able to set the reduction rate of the input effective area of the touch panel.
Furthermore, the display area display position and the input effective area when the hold mode is set may be set separately, or the position, size and shape of the touch non-responsive area in the hold mode can be set by the user independently. You may be able to do it.

The contact input determination unit 8 is a part that detects a touched position of the touch panel as the input unit 3 and determines whether or not the detected contact position is within the input effective area.
The contact position is acquired as, for example, coordinate values (X, Y) when the entire touch panel is viewed as one plane. Therefore, the coordinate value of the contact position is within the plane coordinate range indicating the input effective area of the touch panel. It may be determined by whether or not is included.
When it is determined that the touch position of the touch panel is within the input effective area, a predetermined function corresponding to the touch position is executed.

The storage unit 11 is a part for storing information necessary for executing each function of the present invention, setting values, and the like, and is stored in a semiconductor storage element such as ROM, RAM, flash memory, HDD, SSD, etc. Devices and other storage media are used.
The storage unit 11 stores, for example, display data 12, a mode setting value 13, a reduction rate 14, and a display position 15.

The display data 12 is data displayed on the display unit 2.
Based on the set mode, the control unit 1 determines the display size (reduction ratio) and display position of the display data, and the display adjustment unit 6 corresponds to the determined display size and display position. Display data 12 is displayed.

The mode setting value 13 is data indicating the usage mode of the current mode, and stores, for example, a numerical value corresponding to the mode set by the switching setting unit 4.
As the mode setting value 13, there are two modes, a normal mode and a hold mode. For example, “0” is set in the normal mode, and “1” is set in the hold mode.
Based on the mode setting value 13, the reduction rate and display position of the display data are determined.

The reduction ratio 14 is a numerical value indicating the size (display size) of the display area for displaying the display data with respect to the display screen, and means the display size of the display area displayed in the hold mode.
As described above, the reduction ratio 14 may be fixedly set in advance, but may be stored so that it can be changed by the user.
When the display area and the input effective area are changed in conjunction with each other, this reduction ratio is also the reduction ratio of the input effective area of the touch panel.

The display position 15 is a preset position on the display screen of the display unit of the reduced display area displayed in the hold mode.
As the display position 15, for example, coordinate values (X coordinate, Y coordinate) on the display screen of four vertices indicating a rectangular display area are set.
The display position 15 may be fixedly set in advance, but may be set and changed to an arbitrary coordinate value by the user.
When the display area and the input effective area are changed in conjunction with each other, the display position 15 is the same as the position of the input effective area on the touch panel.

<Adjustment processing of display area and input effective area>
FIG. 5 shows a flowchart of the adjustment process of the display area and the input effective area according to the present invention.
Here, among the functions executed by the control unit 1, only the control functions for the display unit and the touch panel are shown.

  This control function mainly detects the position where the touch input is made on the touch panel after adjusting the display area and the input effective area based on the mode set by the switching setting unit 4 and the approach detection unit 5, and the touch input If the contact input is valid, the function corresponding to the contact input is executed. If the contact input is invalid, it is assumed that the contact input is not present. is there.

Further, FIG. 5 illustrates a process when both the switching setting unit 4 and the approach detection unit 5 are provided, but when only one of them is provided, the other step is omitted.
For example, when only the changeover switch that is the changeover setting unit 4 is provided and the approach detection unit 5 is not provided, step S3 is omitted, and in the normal mode, steps S6 and S7 are executed.
On the other hand, when only a sensor corresponding to the approach detection unit 5 (also referred to as an approach sensor) is provided, step S2 is omitted, and in step S3, whether the normal mode or the hold mode is selected based on the presence / absence of a detection signal from the sensor. To be judged.

In step S1 of FIG. 5, the control unit 1 checks the current state of the mode switching input.
That is, it is checked whether the current mode is “normal mode” or “hold mode”.
When the switch setting unit (switch) 4 is provided, it is checked which mode the switch is switched to.
Further, when the proximity detection unit (proximity sensor) 5 is provided, the presence or absence of a detection signal from the proximity sensor is checked.

In step S2, when the changeover switch 4 is set to “hold mode”, the process proceeds to step S4, and when it is set to “normal mode”, the process proceeds to step S3.
If a detection signal from the proximity sensor is detected in step S3, the process proceeds to step S4, and if not, the process proceeds to step S6.

In step S4, the display adjustment unit 6 adjusts the display area.
Here, for the display area for the hold mode, the preset reduction ratio 14 and display position 15 are read out, and the display data is reduced according to the reduction ratio and displayed at the display position 15. Change the display data. That is, a predetermined reduced display is performed.

In step S5, the touch area adjustment unit 7 adjusts the input effective area of the touch panel.
When the input effective area is adjusted in conjunction with the display area, the input effective area is reduced using the preset reduction ratio 14 and the display position 15 as in step S4.
In other words, as shown in FIG. 3, for example, a non-touch area (input invalid area) is set in the peripheral portion of the touch panel near the frame 22.

In step S6, since the changeover switch is in the “normal mode” and no detection signal is input from the proximity sensor, the display adjustment unit 6 sets the display area to the normal display area.
That is, the display data is set to be displayed on the entire display screen of the display unit 2.

In step S7, the touch area adjustment unit 7 sets the input effective area as the normal input effective area.
When the display area and the input effective area are linked, the input effective area is set for the entire touch panel.

By the processing from step S1 to S7, a display area for displaying the display data and an input valid area for validating the touch input are set, and the display screen as shown in any of FIGS. Is displayed.
Note that the order of the changeover switch check in step S2 and the proximity sensor detection check in step S3 may be reversed.
Further, the order of the adjustment processes in steps S4 and S5 is not limited to this order, and may be reversed. Similarly, the order of the adjustment processing in steps S6 and S7 may be reversed.

In step S8, the contact input determination unit 8 checks whether or not there is an input (contact input) to the touch panel.
If there is no contact input, the process returns to step S1. Alternatively, step S8 may be looped as it is.

If there is a contact input, the process proceeds to step S9.
In step S9, the position where the contact input is made, that is, the contact input position on the touch panel is detected, and it is determined whether or not the detected contact input position is within the input valid area set in step S5 or S7. .

In step S10, when the contact input position is inside the input effective area, the process proceeds to step S11.
If the contact input position is outside the input valid area, that is, the input invalid area, the contact input is invalidated and the process returns to step S1. Or you may return to step S8.

In step S11, since the position where the contact is input is within the input effective area on the touch panel, the control unit 1 executes a function associated with the contact input position.
For example, if the currently displayed display screen is an application program startup selection screen, and the contact area is input within the display area where the icon of the desired application program is displayed, the display area corresponding to the contact input is supported. The attached application program is started and the function of the application program is executed.
Thereafter, the process returns to step S1.

  As described above, the display area and the touch reaction area (input effective area) are adjusted based on the setting state in the switching setting unit 4 or the detection of the user's holding state by the approach detection unit 5, and the user operates the terminal. If you hold it with a touch non-reactive area (input invalid area) in the periphery of the display screen near the frame of the housing, which is likely to be touched by the hand. Can be prevented. A significant difference from Patent Document 1 is that an application operating on a terminal according to the present invention does not need to be aware of the position and size of a non-touch area (input invalid area). In Patent Document 1, it is necessary to change the position of the touch button in accordance with the position and size of the input invalid area, and it is difficult to appropriately set the position of the touch button unless the application is incorporated in advance in the terminal. An application running on the terminal does not need to be aware of the size and position of the input invalid area, and can run a general-purpose application without malfunction. This is very important because smartphones and tablet terminals often install and use general-purpose applications after purchase, as well as applications installed from the beginning.

  Use the touch panel to prevent malfunctions and prevent the risk of falling by firmly holding the end of the terminal, including the non-touch area (input invalid area) set as described above, by hand. Can reduce fatigue when performing input operations.
