A detection part detects the contact with respect to the front surface of a screen by a user, and the contact with respect to the back surface of a screen.
That is, the detection unit detects whether or not a touch with a user's finger or the like has occurred on the touch panel provided on the front surface of the screen and the touch panel provided on the back surface, and recognizes the contact position as a coordinate position.

The processing unit determines a position in the screen instructed by the user based on success or failure of a predetermined condition, and performs processing associated with the determined position.
That is, the processing unit determines whether the surface that is touched by the user's finger or the like is the front surface, the back surface, or both surfaces based on whether or not a predetermined condition described later is satisfied. It is determined which position on the marked surface is the designated position. And the process according to the determined position is performed.
For example, in a mobile terminal, when a predetermined condition is satisfied, it is recognized that there is a touch on the touch panel on both sides, and the front or back contact position, or the average value of the contact positions is specified as the contact position. To do. When both surfaces are determined as contact surfaces, and then the front surface contact is released, only the back surface contact is detected, and processing corresponding to the contact movement of the user's finger or the like on the back surface is performed.

A change part changes the form of the object memorize | stored in a memory | storage part based on the success or failure of predetermined conditions.
That is, for example, when the contact between the front surface and the back surface on the touch panel is detected, the change unit is specified by the user when the contact position between the object and the both surfaces is detected within a certain range. The size of the object is changed, for example.

In the information display device, the predetermined condition is that both a contact with the front surface and a contact with the back surface are detected, the position of the contact with the front surface, the position of the contact with the back surface, and the position of the object stored in the storage unit. Is satisfied within a predetermined range.
That is, the predetermined condition is that both the touch on the touch panel on the front surface of the screen and the touch on the touch panel on the back surface are detected, and the position of the contact on the front surface and the position of the contact on the back surface are determined by the object on the screen. It is satisfied when it is within a predetermined range in relation to a certain position.

In the information display device, the processing unit determines, by the user, either the position of contact with the front surface or the position of contact with the back surface, or the average position, while a predetermined condition is satisfied. The position is determined as the designated screen position.
That is, when the user's finger or the like is in contact with the touch panel on both sides and in the vicinity of a certain position of the object, the contact position on the touch panel is specified as the front surface, the back surface, or the average position of both.

In the information display device, when the contact with the back surface is not detected after a predetermined condition is satisfied, the processing unit determines the position of the contact with the front surface as the position in the screen instructed by the user.
That is, when the touch of the rear touch panel is not detected after the user's finger touches the touch panel on both sides and a predetermined condition is satisfied, the position of the touch on the front is determined as the position in the screen instructed by the user To do.

In the information display device, when the contact with the front surface is not detected after the predetermined condition is satisfied, the processing unit determines the position of the contact with the back surface as the position in the screen instructed by the user.
That is, after the user's finger or the like touches the touch panel on both sides and a predetermined condition is satisfied, if the touch on the front touch panel is no longer detected, the touch position on the back touch panel is determined as the position specified by the user. It is determined.

According to the present invention, when a predetermined condition is satisfied, the form of the object is changed. For example, when a finger or the like touches the object so as to be sandwiched by the double-sided touch panel, the process of enlarging the object is performed. It is possible to prevent the object from being hidden by a finger or the like and becoming difficult to see.
In addition, when the user performs an object moving operation, the moving process can be performed using the front or back touch panel separately, and the visibility of the object can be improved.

Further, in the information display device of the present invention, the changing unit (1) sets the form of the object to the first size if a predetermined condition is satisfied, and (2) if the predetermined condition is not satisfied, The form of the object is the second size, and the first size is larger than the second size.

That is, when the finger or the like touches the double-sided touch panel, the changing unit increases the shape of the object if the touch position of the touch panel and the position of the displayed object are within a predetermined range. Change to be smaller.

According to the present invention, the information display device can improve the visibility of a user's object by displaying the object large when the finger is in contact with the object with the double-sided touch panel interposed therebetween.

Further, in the information display device of the present invention, the changing unit (1) sets the form of the object to the first size if a predetermined condition is satisfied, and (2) the predetermined condition is not satisfied, While the processing unit determines the position of contact with the front surface as the position in the screen instructed by the user, the form of the object is set to the second size, and (3) the predetermined condition is not satisfied While the processing unit determines the position of contact with the back as the position in the screen instructed by the user, the form of the object is set to the third size, and the first size is greater than the second size. The second size is larger than the third size.

That is, when the finger touches the object so that the object is sandwiched between the double-sided touch panels, the size of the object is increased, and then the object touches only with the front touch panel, and the front touch panel becomes the pointing surface. If so, the object size is set to medium. Further, when the object is touched with a finger so as to sandwich the object with the double-sided touch panel, the object is touched only with the back touch panel, and the size of the object is small when the back touch panel is an instruction surface.

According to the present invention, when the user's finger or the like touches the touch panel on both sides and sandwiches the object, the object is most difficult to see, so the size of the object is maximized.
In addition, when the user's finger or the like is in contact with the object with only the front touch panel, the size of the object is medium, and when the object is in contact with only the rear touch panel, the object is most easily seen. Therefore, the object size is displayed as small.
In this way, the information display device having touch panels on both sides determines the indication surface according to the user's touch operation on the touch panel and changes the size of the object on the screen. Can increase the sex.

Note that the RAM 155 functions as the storage unit 203.

3, “object size” is listed as an item of a changed object form as a storage item in FIG. 3, but other form items such as “object color” may be set.

The display unit 204 displays the shape stored at the stored coordinate position based on the object information stored in the storage unit 203.
For example, as shown in FIG. 4, based on the information stored in the storage unit 203, the object A (401) is displayed on the screen 106 at the position (X1, Y1) as a circle shape, and the object B (402 ) Is displayed as a square shape at the position (X2, Y2). The object size is a default size for both the objects A (401) and B (402).
The image processing unit 152, the LCD controller 156, and the like function as the display unit 204.

The detection unit 205 detects whether or not the first touch panel 107 disposed on the front surface of the screen 106 and the second touch panel 108 disposed on the back surface are in contact with each other.
For example, as shown in FIG. 4, the object A (401) is moved on the first touch panel 107 on the front surface with a finger toward the object B (402). Then, for example, as illustrated in FIG. 10, the detection unit 205 detects the coordinate position of the object A with the passage of time, and updates the value of the coordinate position of the storage unit 203 each time.
In the present embodiment, when the object A (401) is moved toward the object B (402) using a finger or the like, the coordinates of the object A (401) are (10, 30) as time passes. It changes to (15, 30), (20, 30), (28, 30), the detection unit 205 detects the change, and updates the value of the object position in the storage unit 203. Details will be described later.
Note that the touch panel controller 157 and the CPU 151 function as the detection unit 205.

The processing unit 206 determines a position in the screen instructed by the user based on success or failure of a predetermined condition, and performs a process associated with the determined position.
Here, the predetermined condition is that both the contact with the first touch panel 107 on the front surface of the screen 106 and the contact with the second touch panel 108 on the back surface are detected, and the contact position with respect to the front surface and the contact position with respect to the back surface. And the position of the object stored in the storage unit 203 is within a predetermined range.

The predetermined condition is, for example, a case where the position of the thumb that has contacted the first touch panel 107 on the front surface, the index finger that has contacted the second touch panel 108 on the back surface, and the object displayed on the screen is within a predetermined range. Say. More specifically, it means a state in which an object is sandwiched between the front and back of the screen 106 with two fingers.
If such a condition is set, as will be described later, processing such as changing the form of the object, for example, displaying the object in a large size, is performed.

The predetermined range can be determined as an arbitrary range. For example, the finger touching the first touch panel 107, the finger touching the second touch panel 108, and the position of the displayed object are included in a circle having a diameter of 5 mm.

Further, the processing unit 206 performs a process of determining the surface of the touch panel and the position on the touch panel instructed by the user depending on whether or not a predetermined condition is satisfied.
That is, when a predetermined condition is satisfied, for example, the thumb that touches the first touch panel 107 on the front surface, the index finger that touches the second touch panel 108 on the back surface, and the position of the displayed object are within a predetermined range. If there is, the processing unit 206 is in a position in the screen in which the position of contact with the first touch panel 107 on the front surface, the second touch panel 108 on the back surface, or the average position of both positions is instructed. Determine as.
In this case, the double-sided touch panel functions as an effective surface that can accept instructions.

When the contact with the second touch panel 108 on the back surface is not detected after the predetermined condition is satisfied, the processing unit 206 determines the position of the contact with the first touch panel 107 on the front surface in the screen instructed by the user. Specify as location.
That is, after the finger touches both the front and back touch panels, when the contact with the second touch panel 108 on the back is not detected by the detection unit 205, the finger touches only the first touch panel 107 on the front. The contact position of the finger on the first touch panel 107 on the front surface is specified as an instruction position by the user.
In this case, the front touch panel functions as an effective surface that can accept instructions. Accordingly, the content instructed only by the first touch panel 107 is processed as a valid instruction, and the content instructed by the second touch panel 108 is not input.

In addition, when a contact with the first touch panel 107 on the front surface is not detected after a predetermined condition is satisfied, the processing unit 206 displays a screen instructing the position of the contact with the second touch panel 108 on the back surface by the user. Identifies as the position within.
That is, after the finger touches both the front and back touch panels, when the touch on the first touch panel 107 on the front face is not detected by the detection unit 205, the finger touches only the second touch panel 108 on the back face. In this state, the contact position of the finger on the second touch panel 108 on the back surface is specified as the instruction position by the user.
In this case, the back touch panel functions as an effective surface that can accept instructions. Accordingly, the content instructed only by the second touch panel 108 is processed as a valid instruction, and the content instructed by the first touch panel 107 is not input.

The changing unit 207 changes the form of the object stored in the storage unit 203 based on whether or not a predetermined condition is met.
As described above, the predetermined condition typically refers to a case where the finger is in contact with the double-sided touch panel and the object displayed on the screen is present near the finger in contact.

Processing of the changing unit 207 corresponding to the specified indication surface will be described with reference to FIGS. 5 and 6.
When the predetermined condition is satisfied, either the contact position of the front or back touch panel or the average value of both is determined as the user's instruction position, and the specified instruction surface is “both sides” of the touch panel.
Further, after the predetermined condition is satisfied, when the contact on the back surface is lost, the front surface becomes the indicating surface, and the indicating surface at this time is the “front surface” of the touch panel.
After the predetermined condition is established, when the front surface is no longer contacted, the back surface is the indicating surface, and the indicating surface at this time is the “rear surface” of the touch panel.

The changing unit 207 can change the form of the object. Examples of the changing form include the size of the object and the color of the object.
FIG. 5 is a diagram illustrating a correspondence relationship in the case where the size of the object is changed corresponding to the specified indication surface in the change unit 207. When both surfaces are specified as the instruction surface, it is assumed that the predetermined condition that the front contact position, the rear contact position, and the object position are within a predetermined range is satisfied.
As illustrated in FIG. 5, the change unit 207 increases the size of the object when the specified pointing surfaces are both surfaces of the touch panel. When the specified indication surface is the front surface of the touch panel, the size of the object is set to the middle. If the specified pointing surface is the back surface of the touch panel, the size of the object is reduced.

When the predetermined condition is satisfied, the object is hardly visible. Therefore, by increasing the size of the object, the position of the object can be clearly shown to the user.
Also, when the predetermined condition is not satisfied and the front surface is the pointing surface, it is assumed that the finger is at a position close to the object on the display screen, so the size of the object is set to the middle.
When the predetermined condition is not satisfied and the back is the pointing surface, the distance between the finger and the object is short, but the finger is on the back of the display screen, so that the object on the screen is easily visible. . Therefore, the size of the object is made small.
The storage unit 203 updates the data in the storage unit so as to change the data of the object size each time the size of the object is changed by the changing unit 207.

FIG. 6 is a diagram illustrating a correspondence relationship between the specified indication surface and the color of the object in the change unit 207. Also in this figure, when both sides are specified as instruction surfaces, it is assumed that the predetermined condition that the front contact position, the rear contact position, and the object position are within a predetermined range is satisfied.
As illustrated in FIG. 6, the changing unit 207 sets the color of the object to red when the specified pointing surfaces are both surfaces of the touch panel. When the specified pointing surface is the front surface of the touch panel, the color of the object is yellow. When the specified pointing surface is the back surface of the touch panel, the color of the object is green.

When the predetermined condition is satisfied, it is difficult to see the object, so that the color of the object can be made red and the position of the object can be shown conspicuously to the user.
Also, when the predetermined condition is not satisfied and the front is the pointing surface, it is assumed that the distance between the finger and the object is close and the finger is on the display screen. To clarify.
When the predetermined condition is not satisfied and the back surface is the pointing surface, the distance between the finger and the object is short, but the finger is on the back surface of the display screen, so that the object is easily visible. Therefore, the color of the object is a relatively inconspicuous green.
Each time the color of the object is changed by the changing unit 207, the storage unit 203 updates the color data of the object so as to change to the corresponding color.

Note that the size of the object or the color of the object changed by the changing unit 207 is not limited to the above-described example, but includes various modifications.
The size or color of the object should not be changed depending on whether the pointing surface is specified as double-sided, front-side, or back-side, but only when both sides are specified as pointing-points Is also possible.

(Operation processing)
The operation process of the portable terminal 100 having the above configuration will be described with reference to the flowchart shown in FIG.
When the portable terminal 100 is turned on, the process is started through an initialization process. In the initialization process, a program stored in the ROM 201 of the cartridge 200 as information necessary for starting information processing is read into the RAM 155.
Since the coordinate positions and forms of the object A and the object B are stored in the storage unit 203, the CPU 151 refers to the data in the storage unit 203 and reads the data of the coordinate positions and the form data.
The image data processed by the image processing unit 152 based on the read data is displayed on the screen 106 as an object image via the LCD controller 156.

On the other hand, when the operation of the touch panel is started by the user, first, it is detected whether the valid touch panel that accepts the current operation is the front surface or the back surface (step S901). Then, the detection unit 205 detects contact between the front surface and the back surface of the double-sided touch panel (step S902).

If contact between the front surface and the back surface of the double-sided touch panel is detected, it is determined whether the previous contact is in contact with the front surface, the back surface, or both surfaces, and the current contact is also in contact with the front surface, back surface, or both surfaces (step S903). . That is, when the previous and current contact states are detected, it is determined whether or not there has been a state where both sides have not touched both surfaces, a so-called release state.

When there is no release state in the previous or current contact detection (YES; step S903), the next effective surface is determined according to the tables shown in FIGS.
When there is a release state in the previous or current contact detection (NO; step S903), the tables in FIGS. 7 and 8 are not applied, and the current effective surface remains unchanged.

The surface of the touch panel on which the next operation is valid is determined according to which is the effective surface of the current touch panel and which touch panel is the previous contact state or the current contact state.
Specifically, the surface on which the next operation is valid is determined according to the tables shown in FIGS.

FIG. 7 is a diagram showing a table 700 showing combinations for determining the effective surface of the next operation when the previous touch state on the touch panel is either the front surface or the back surface.
The table 700 includes a column 701 indicating the previous contact state, a column 702 indicating the current contact state, a column 703 indicating the current effective surface, and a column 704 indicating the next effective surface. It is remembered.

The table 700 shows a method of determining the next effective surface when the previous contact state is the front surface or the back surface of the touch panel on the assumption that the current effective surface is the front surface.
That is, when the current effective surface is the front surface, the previous contact state is the front surface, and the current contact state is the front surface, the next effective surface is the front surface. If the current effective surface is the front surface, the previous contact state is the front surface, and the current contact state is the back surface, the next effective surface is the front surface. If the current effective surface is the front surface, the previous contact state is the front surface, and the current contact state is the both surfaces, the next effective surface is the front surface.

、 If the current effective surface is the front surface, the previous contact state is the back surface, and the current contact state is the front surface, the next effective surface is the front surface. If the current effective surface is the front surface, the previous contact state is the back surface, and the current contact state is the back surface, the next effective surface is the front surface. If the current effective surface is the front surface, the previous contact state is the back surface, and the current contact state is both surfaces, the next effective surface is the front surface.

Further, the table 700 shows a method of determining the next effective surface when the previous contact state is the front surface or the back surface of the touch panel on the assumption that the current effective surface is the back surface.
That is, when the current effective surface is the back surface, the previous contact state is the front surface, and the current contact state is the front surface, the next effective surface is the back surface. If the current effective surface is the back surface, the previous contact state is the front surface, and the current contact state is the back surface, the next effective surface is the back surface. If the current effective surface is the back surface, the previous contact state is the front surface, and the current contact state is the both surfaces, the next effective surface is the back surface.

、 If the current effective surface is the back surface, the previous contact state is the back surface, and the current contact state is the front surface, the next effective surface is the back surface. If the current effective surface is the back surface, the previous contact state is the back surface, and the current contact state is the back surface, the next effective surface is the back surface. If the current effective surface is the back surface, the previous contact state is the back surface, and the current contact state is both surfaces, the next effective surface is the back surface.

FIG. 8 is a diagram showing a table 800 showing a method for determining the next effective surface when the current effective surface is the front surface or the back surface and the previous contact state is double surface.
The table 800 includes a column 801 indicating the previous contact state, a column 802 indicating the current contact state, a column 803 indicating the current effective surface, and a column 804 indicating the next effective surface. It is remembered.

If the current effective surface is the front surface, the previous contact state is double-sided, and the current contact state is the front surface, the next effective surface is the front surface. If the current effective surface is the front surface, the previous contact state is double-sided, and the current contact state is the back surface, the next effective surface is the back surface. If the current effective surface is the front surface, the previous contact state is double-sided, and the current contact state is double-sided, the next effective surface is the front surface.
If the current effective surface is the back surface, the previous contact state is double-sided, and the current contact state is the front surface, the next effective surface is the front surface. If the current effective surface is the back surface, the previous contact state is double-sided, and the current contact state is the back surface, the back surface is the next effective surface. If the current effective surface is the back surface, the previous contact state is double-sided, and the current contact state is double-sided, the back surface is the next effective surface.

As described above, the effective surface of the touch panel is not switched from the current effective surface to the next effective surface depending on the current contact state when the previous contact state is only one of the front surface and the back surface.
On the other hand, in the case where the previous contact state is double-sided, if the subsequent current contact state touches either the front or the back, the effective surface is switched to the touched touch panel side.

In the table 800, when the previous contact state is double-sided, it is assumed that the front contact position, the back contact position, and the object position are within a predetermined range.

Based on the table 700 and 800 in FIG. 7 and FIG. 8, the effective surface that is valid for the next input is determined based on which of the previous contact surface, the current contact surface, and the current effective surface. (Step S904).
Then, the pointing position is specified according to the specified pointing surface, that is, the contact surface (step S905), and the form of the object is changed based on FIG. 5 or 6 by the changing unit 207 (step S906).

As shown in FIG. 5 or FIG. 6, the change of the form in the change unit 207 is to increase the size of the object if the size of the object is set as a change target when a predetermined condition is satisfied. If the color of the object is set as a change target, the object is changed to red.

When the form of the object is changed by the change unit 207, the form stored in the storage unit 203 is updated to the changed form.
After updating the storage unit 203 in the changed form, the display unit 203 displays the object on the screen 106 in the changed form (step S907).
Then, the other processes of the information display process (step S908) are repeated to repeat the above process.

As shown in FIG. 5 or FIG. 6, when the back side is specified as the pointing surface, if the object size is set as a change target, the object size is reduced and the object color is changed. If it is set as a target, the object is changed to green.

Further, when the front surface is specified as the user instruction surface, as shown in FIG. 5 or FIG. 6, if the object size is set as a change target, the object size is set to the middle, and the object If the color of is set as the change target, the object is changed to yellow.

If the touch panel on both sides is not touched by the previous or current contact, that is, if it is in the released state, the next effective surface is not determined. Then, the size of the object may be maintained according to the current effective surface, or may be returned to a predetermined default size.

A more specific flow of processing operations in the present embodiment will be described with reference to FIG. 4, screen transition diagrams of FIGS. 11 to 13 and a table 1000 of FIG.
As shown in FIG. 4, a case will be described in which an object A (401) is moved in the direction of an object B (402) by bringing a finger into contact with the first touch panel 107 on the front surface.

In the present embodiment, as shown in FIG. 3, the data in the storage unit 203 is stored for the object A with the coordinate position (X1, Y1) and the shape ◯. Object B is stored with coordinate position (X2, Y2) and shape □.
Based on the stored information, the object A (401) and the object B (402) are displayed on the screen as shown in FIG. At this time, the sizes of the object A (401) and the object B (402) are stored in the storage unit 203 as “medium” which is a default size, and are displayed on the screen with this large size.

When the user moves the object A (401), the user places, for example, a thumb on the object A (401). At this time, the position of the thumb on the first touch panel 107 is detected by the detection unit 205.
Specifically, when the user's thumb is on the object A, the contact position is specified as a coordinate value of (10, 30), and this is also specified as the user's designated position.

The table 1000 in FIG. 10 shows that the presence / absence of coordinates on the front and rear touch panels of the user and the coordinate positions thereof, and the positions of the first touch panel 107 (front touch panel), the second touch panel 108 (rear touch panel), and the object B are within a predetermined range. The specified indication surface and the size of the object are shown as the detection time elapses.
In the present embodiment, the coordinate position of the object B is (30, 30) and does not move.

In the table 1000, the item of detection time (1001) is expressed by an integer value with the vertical synchronization interrupt period as a unit.
Further, when the user's finger or the like touches the touch panel, if it is detected that the first touch panel 107 is touched, “front” is stored, and if it is detected that the second touch panel 108 is touched, “Back” is stored.
In the item of “contact surface” (1002), when it is detected that the “front surface” is touched, the coordinate position information indicates that the coordinate position information is detected when it is detected that the “back surface” is touched. Location information is written.

The item “predetermined range” (1003) is an item indicating whether the front contact position, the back contact position, and the position of the object B are within a predetermined range.
The predetermined range is determined, for example, based on whether or not the above-mentioned three positions are included in a circle with a radius of 2 mm. When the predetermined range is not included, the flag is set to 0, and when included, the flag is set to 1. To do.

The item of “specified indication surface” (1004) is an item that describes which surface the position indicated by the current user is on. When the front is a valid pointing surface, "Front" and when the back is a valid pointing surface, "Back" and the front or back, or the average of both functions as a valid pointing position Shows “both sides”.

The item “object size” (1005) indicates the size of the object corresponding to the surface specified as the instruction surface. If the front side is specified as the pointing surface, the object size is determined as “medium”, if the back side is determined as the pointing surface, “small”, and if both sides are determined as the pointing surface, the size is determined as “large”. Is done.

As shown in the table 1000, when the user touches the thumb on the object A at the detection time 1000, the contact surface is the front surface, and the position of contact with the first touch panel 107 (hereinafter referred to as “front touch panel”). The coordinate position is (10, 30), and the coordinate position of the second touch panel 108 (hereinafter referred to as “rear touch panel”) is not detected.
If the predetermined range is set to be within a radius of 2 mm from the center of the object B, it does not fall within the predetermined range, the indication surface is specified as “front”, and the size of the object is initially stored in the storage unit 203 as a default. The size is “medium”.

The user moves the object B in the direction of the object B while touching the thumb on the object A on the front touch panel.
In the detection time 1200, the contact surface is the front surface, the coordinate position of the contact position of the front touch panel is (15, 30), and the coordinate position of the rear touch panel is not detected. This coordinate position relationship does not fall within the predetermined range, the pointing surface is specified as “front”, and the size of the object is “medium” which is the size initially stored in the storage unit 203 as a default.

Furthermore, at the detection time 1300, it is assumed that the object A further approaches the object B, and the index finger is brought into contact with the touch panel on the back.
At this time, the front surface and the back surface are detected as contact surfaces, the contact coordinate position of the front touch panel is (20, 30), and the contact coordinate position of the rear touch panel is (25, 30). This coordinate position relationship does not fall within the predetermined range, the pointing surface is specified as “front”, and the size of the object is “medium” which is the size initially stored in the storage unit 203 as a default.

In the detection time 1400, the thumb is in contact with the front touch panel and the index finger is in contact with the rear touch panel, and the front and back surfaces of the contact surface are detected. The coordinate position of the touch on the front touch panel is (28, 30), and the coordinate position of the touch on the rear touch panel is (30, 30). This coordinate position relationship falls within a predetermined range, the pointing surface is “both sides”, and the position of the front or back or the average value of these is the pointing position.

At this point, since the user's operation satisfies a predetermined condition, the changing unit 207 changes the form of the object, that is, changes the size of the object to “large”.
Accordingly, “medium” which is the size stored in the storage unit 203 is changed to “large”. The table 300 in FIG. 3 shows the state of the storage unit 203 after the size of the object B is changed from “medium” to “large”. Then, the object B is displayed with the changed size.
By being displayed in this way, the object B can be displayed without being hidden by the user's finger, and the user can clearly recognize the object B.

At detection times 1500 and 1600, the finger is separated from the rear touch panel, and the finger is in contact with only the front touch panel. As shown in FIG. 5, this state is a state in which the previous contact state is double-sided and the current contact state is front-side. The effective surface where the user's operation is effective is the front surface.
Further, the coordinate position of the touch on the front touch panel is (25, 27), the coordinate position of the rear touch panel is not detected, and the position of “front” is the designated position. The specified indicating surface at this time is the front surface.
Accordingly, the changing unit 207 changes the shape of the object, that is, changes the size of the object from “large” to “medium”. In the changed object form, “large” which is the size stored in the storage unit 203 is changed to “medium”. Then, the object B is displayed with the changed size.
Since the front surface is an effective surface at this time, as shown in the table 700, the effective surface is not changed even if the finger touches only the back surface.

In the detection time 1700, since the user's finger is in contact with both the front touch panel and the rear touch panel, the front surface and the back surface are detected as contact surfaces.
The coordinate position of the touch on the front touch panel is (20, 25) and the coordinate position of the touch on the rear touch panel is (25, 30), but the position of the object B, the touch position of the front touch panel of the user, and the touch of the rear touch panel. Since the position is not within the predetermined range, the predetermined condition is not satisfied, the position of “front” is the designated position, and the front is the designated designated surface.
Since the change unit 207 does not change the shape of the object, the size of the object remains “medium”.

In the detection time 1800, the user's finger contacts the front touch panel and the rear touch panel, and the front and back are detected as contact surfaces. The coordinate position of the touch on the front touch panel is (28, 30), the coordinate position of the touch on the rear touch panel is (30, 30), and the position of the object B, the touch position of the front touch panel, and the touch position of the rear touch panel are predetermined. Since it is within the range, a predetermined condition is satisfied, the position of the average value of the front surface or the back surface or both is the user's instruction position, and the specified instruction surface is “both sides”.

At this point, since the user's operation satisfies the predetermined condition, the changing unit 207 changes the form of the object, that is, changes the size of the object from “medium” to “large”. By changing the form of the object, the size initially stored in the storage unit 203 is changed from “medium” to “large”. Then, the object B is displayed with the changed size.

At the detection time 1900, the contact of the front touch panel that was in contact at the detection time 1800 is released, and only the rear touch panel is in contact. As shown in the table 800, this state is a state in which the previous contact state is double-sided and the current contact state is the back side.
Therefore, only the back surface is detected as the contact surface, the contact of the front touch panel is not detected, and the coordinate position of the touch of the rear touch panel is (25, 30), but the predetermined condition is not satisfied, and the “rear” position Is the designated position, and the back side is the designated designated surface.
When the back side is the specified pointing surface, the changing unit 207 changes the object form from “large” to “small”, and the size of the object stored in the storage unit 203 is also changed from “large” to “small”. Is updated. Then, the object B is displayed on the screen in a changed form.
At this time, the effective surface is the back surface, and even if the contact is switched to the front surface, the effective surface is not changed to the front surface as shown in the table 700.

In the detection time 2000, as in the detection time 1900, since only the back touch panel is touched, only the back surface is detected and the predetermined condition is not satisfied.
Therefore, the specified indication surface remains the back, and the size of the object B is “small” as in the detection time 1900, and the data in the storage unit 203 is not changed.

Although the case where the size of the object is changed according to the change of the specified indication surface has been described, it is also possible to change the color of the object as shown in FIG. That is, it can be changed to yellow when the front surface is designated, green when the back surface is designated, and red when both surfaces are designated.

As described above, in the present embodiment, the portable terminal can change the size of the object according to the positional relationship between the touch surface of the user touch panel and the object. Thereby, when the object is in contact with only the front surface, the size of the object is set to be medium, and when the object is in contact with both sides so as to sandwich the object, the object can be displayed in a large size.
By changing the form of the object, the user can clearly recognize the target object without hiding it with his / her finger.
Conversely, if the back side is the pointing surface, the image of the object can be clearly recognized, so that the object is displayed small and the user can also recognize that the current pointing surface is the back side.

Specifically, the object shape change described above is displayed on the screen as shown in FIGS.
As shown in FIG. 11, the user moves the object A (401) toward the object B (402) by bringing the thumb into contact with the first touch panel 107 on the front surface. Since the user's thumb is in contact only with the front surface, the object B (402) is displayed as a medium having a size stored as a default in the storage unit 203.
In addition, when the user's finger touches both surfaces of the first touch panel 107 and the second touch panel 108 and satisfies a predetermined condition, the object B is similarly medium when the contact is released from the second touch panel 108. Displayed in the size of.

As shown in FIG. 12, after moving the object A (401) toward the object B (402) on the first touch panel 107 using the thumb, the object B is brought into contact with the index finger from the back side. .
When the state is in such a positional relationship, since a predetermined condition is satisfied, the object B (402) becomes large and is easy to see.

Thereafter, as shown in FIG. 13, when the thumb is released from the first touch panel 107 on the front surface and the index finger is in contact with only the second touch panel 108 on the rear surface, the object B (402) becomes smaller.
When the user's finger is in contact only with the second touch panel 108 on the back surface, there is no object such as a finger blocking the visual field on the front surface, so the object B may be displayed in a small size.
In this state, since only the second touch panel 108 serves as an instruction surface, the user performs an object instruction operation from the back.

In this embodiment, by changing the size and color of an object that is a form of the object according to a predetermined condition, it is possible to prevent the object on the screen from being obstructed by a user's finger and becoming difficult to see. be able to.
Furthermore, since it is possible to display which screen is instructed by the user by changing the size and color of the object, it is possible to instruct the screen in a manner that is easy for the user to operate.

Further, in the present embodiment, it has been described that the size and color of an object are changed according to a predetermined condition as a change in the form of the object. However, the change in the form is limited to that described in the present embodiment. Not.
For example, when a predetermined condition is satisfied, it is possible to perform an action such that the object comes out from between the fingers that are pinched, for example, a movement that the green soybean comes out from the sheath. Further, when the object is a character, the form of the character may be changed.

Furthermore, in the present embodiment, an example of changing the form of the destination object has been described, but the target of the object whose form is changed is not limited to the destination object.
For example, the form of the object being moved may be changed, or the form of both the object being moved and the object being moved may be changed. The object whose form is changed can be appropriately selected and adopted according to the content handled by the portable terminal.

According to the present invention, an object that is difficult to visually recognize with a finger can be easily recognized by a change in the form of the object, and the user can visually recognize that switching of the instruction surface is possible due to the change in the form of the object. The operability of the double-sided touch panel can be improved.
In particular, in a portable game device, it is possible to diversify game effects and to make it possible to visually recognize that the indication surface can be switched by double-sided contact by changing the form of the object. It is possible to expand the range of sex or game specifications.

In this application, the applicant claims priority based on Japanese Patent Application No. 2011-118111 dated May 26, 2011, and incorporates the contents of the basic application into this application.

As described above, according to the present invention, in the information display device in which the touch panels are arranged on both sides of the screen, the information display device that can improve the movement operability of the object on the screen by the contact operation with respect to the double-sided touch panel. , An information display method, a non-transitory recording medium, and a program for realizing these on a computer can be provided.
