[0008] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. (Embodiment 1) 1(a) to 1(d) are perspective views showing an example of an information processing device 1 to which the present embodiment is applied. FIG. 1(a) is a diagram showing the information processing device 1 in an open state (a state in which the folding angle θ described below is 180°). FIG. 1(b) is a diagram showing the information processing device 1 in a folded state (a state in which the folding angle θ is 120°). FIG. 1(c) is a diagram showing the information processing device 1 in a folded state (a state in which the folding angle θ is 240°). FIG. 1(d) is a diagram showing the information processing device 1 in a closed state (a state in which the folding angle θ is 0°). FIG. 2 is a diagram showing an example of the hardware configuration of the information processing device 1 to which the present embodiment is applied. The information processing device 1 of this embodiment is a device equipped with a display unit that displays images, and is, for example, a tablet terminal, a smartphone, a PDA (Personal Digital Assistant), a game device, or a PC (Personal Computer).

[0009] The information processing device 1 of this embodiment includes a foldable display unit 10 having a display area 20 for displaying an image, a detection unit 30 for detecting the bending angle θ of the display unit 10, and a control unit 50 as an example of a display control device or display control unit for controlling the display in the display area 20 of the display unit 10 based on the detection result by the detection unit 30.

[0010] Display unit 10 of this embodiment has a rectangular plate shape with a long axis direction and a short axis direction, and has a display area 20 provided on one surface. Display unit 10 displays images in display area 20 and accepts user operations on display area 20 based on control by control unit 50. Display unit 10 is not particularly limited as long as it has the function of displaying images and the function of accepting user operations, and for example, a liquid crystal display or an organic EL display equipped with a touch panel can be used.

[0011] 1(b) to 1(c), the display unit 10 is bendable around a bending portion 15 extending along the minor axis. Note that the configuration for making the display unit 10 bendable is not particularly limited, but examples include the use of an elastic material that can be deformed by physical force, one or more hinges, etc. The display area 20 is composed of a first display area 21 and a second display area that are arranged side by side in the long axis direction with the bent portion 15 sandwiched therebetween.

[0012] In this embodiment, the bent portion 15 is provided in the center in the long axis direction of the display unit 10. As a result, the first display region 21 and the second display region 22 have the same area. The position of the bent portion 15 is not limited to the center in the long axis direction of the display unit 10, and may be a position where the areas of the first display region 21 and the second display region 22 are different. Also, the bent portion 15 may extend along the long axis direction of the display unit 10.

[0013] The detection unit 30 detects the acceleration of the display unit 10. As shown in Figures 1(a) to 1(c) and 2, the detection unit 30 has a first acceleration sensor 31 that detects the acceleration in the first display region 21 of the display unit 10, and a second acceleration sensor 32 that detects the acceleration in the second display region 22 of the display unit 10. The first acceleration sensor 31 detects, as the acceleration of the first display region 21, acceleration in the long axis direction of the display unit 10, acceleration in the short axis direction of the display unit 10, and acceleration in a direction perpendicular to the first display region 21 (i.e., a direction perpendicular to the long axis direction and the short axis direction). Similarly, the second acceleration sensor 32 detects, as the acceleration of the second display region 22, acceleration in the long axis direction of the display unit 10, acceleration in the short axis direction of the display unit 10, and acceleration in a direction perpendicular to the second display region 22 (i.e., a direction perpendicular to the long axis direction and the short axis direction).

[0014] The first acceleration sensor 31 and the second acceleration sensor 32 detect the acceleration of the first display area 21 and the second display area 22 continuously or periodically at predetermined timings while the information processing device 1 is running. Then, the detection unit 30 outputs the acceleration of the first display area 21 detected by the first acceleration sensor 31 and the acceleration of the second display area 22 detected by the second acceleration sensor 32 to the control unit 50. Details will be described later, but the control unit 50 obtains the bending angle θ of the display unit 10 and the orientation of the display unit 10 from the acceleration of the first display area 21 and the acceleration of the second display area 22 output from the detection unit 30.

[0015] Here, the bending angle θ of the display unit 10 means the angle formed between the first display area 21 and the second display area 22 of the display unit 10, as shown in FIGS. 1(a) to 1(c). In the information processing device 1 of the present embodiment, the display unit 10 is configured to be foldable so that the folding angle θ is in the range of 0° or more and less than 360°. For example, a folding angle θ of 0° means that the display unit 10 is closed, and the first display area 21 (see FIG. 1(a)) and the second display area 22 (see FIG. 1(a)) face each other, as shown in FIG. 1(d). A folding angle θ of 180° means that the first display area 21 and the second display area 22 face in the same direction and are flat, as shown in FIG. 1(a).

[0016] The orientation of display unit 10 refers to the orientation of display unit 10 relative to the orientation of an image displayed in display area 20. In information processing device 1 of the present embodiment, the orientation of display unit 10 can be switched between a first orientation (see FIGS. 4 to 6, which will be described later) in which the up-down direction of an image displayed in display area 20 is aligned with the minor axis direction of display unit 10, and a second orientation (see FIGS. 7 and 8, which will be described later) in which the up-down direction of an image displayed in display area 20 is aligned with the major axis direction of display unit 10, depending on, for example, how the information processing device 1 is used by a user. When the orientation of display unit 10 is the first orientation, an image is displayed in display area 20 with first display area 21 and second display area 22 aligned horizontally on display unit 10. When the orientation of display unit 10 is the second orientation, an image is displayed in display area 20 with first display area 21 and second display area 22 aligned vertically on display unit 10.

[0017] Note that, although detection unit 30 in this embodiment uses first acceleration sensor 31 and second acceleration sensor 32 that detect the acceleration of display area 20, the present invention is not limited to this. As long as control unit 50 can acquire folding angle θ of display unit 10 and the orientation of display unit 10 based on the detection result by detection unit 30, detection unit 30 may use an angular velocity sensor, a geomagnetic sensor, or the like, or a combination of multiple types of sensors.

[0018] As shown in FIG. 2, the control unit 50 includes a CPU (Central Processing Unit) 51, a ROM (Read Only Memory) 53, and a RAM (Random Access Memory) 55. The CPU 51 is an example of a processor, and realizes various functions described below by loading various programs stored in the ROM 53 or the like into the RAM 55 and executing them. The RAM 55 is a memory used as a working memory or the like for the CPU 51. The ROM 53 is a memory that stores various programs and the like to be executed by the CPU 51.

[0019] The control unit 50 acquires the acceleration of the first display region 21 and the acceleration of the second display region 22 output from the detection unit 30. Then, the control unit 50 acquires the folding angle θ of the display unit 10 and the orientation of the display unit 10 from the acceleration of the first display region 21 and the acceleration of the second display region 22.

[0020] Furthermore, the control unit 50 controls the display in the display area 20 of the display unit 10. Although details will be described later, the control unit 50 displays a reception unit 70 (see FIG. 4 and the like, which will be described later) in the display area 20, which receives operations by the user, based on the bending angle θ of the display unit 10 and the orientation of the display unit 10. The reception unit 70 is an image displayed in the display area 20 for receiving input of characters and the like by operation such as contact (touch) with a user's fingertip or a touch pen. Examples of the reception unit 70 include a software keyboard displayed in the display area 20 and various buttons displayed in the display area 20. In the description of this embodiment, characters and the like refer to symbols used when creating words, sentences, mathematical expressions, and the like, and include not only characters input by operating the reception unit 70, but also symbols, pictograms, stamps, and the like.

[0021] Incidentally, in an information processing device 1 having a foldable display unit 10, when the reception unit 70 is displayed in the same manner in the display area 20 regardless of the bending angle θ of the display unit 10, the operability of the user inputting information into the reception unit 70 may be reduced depending on the bending angle θ of the display unit 10. In contrast, in information processing device 1 of the present embodiment, control unit 50 acquires bending angle θ of display unit 10 from the detection result by detection unit 30. Then, control unit 50 displays reception unit 70 in display area 20 in different modes depending on bending angle θ of display unit 10. As a result, in information processing device 1 of the present embodiment, a decrease in operability of input by a user to reception unit 70 is suppressed compared to when reception unit 70 is displayed in display area 20 in the same mode regardless of bending angle θ of display unit 10. The processing performed by the control unit 50 and the state of the reception unit 70 displayed in the display area 20 of the display unit 10 based on the control by the control unit 50 will be described in detail below.

[0022] FIG. 3 is a flowchart showing the procedure of the process executed by the control unit 50 of this embodiment. When the information processing device 1 is powered on and started up, the detection unit 30 starts detecting the acceleration of the first display area 21 and the second display area 22. The control unit 50 also displays an image such as a predetermined home screen in the display area 20 of the display unit 10, and starts monitoring whether or not the user has input an operation into the display area 20. Note that in the information processing device 1, when the display unit 10 is closed (i.e., when the bending angle θ of the display unit 10 is 0°), no image is displayed in the display area 20. Therefore, the following processing is performed when the display unit 10 is open, i.e., when the bending angle θ of the display unit 10 is greater than 0°.

[0023] First, the control unit 50 determines whether or not a predetermined operation has been performed by the user on the display unit 10. In this example, the control unit 50 determines whether or not a predetermined input start operation has been performed by the user on an image displayed in the display area 20 of the display unit 10 as the predetermined operation on the display unit 10 (step 101). Here, the input start operation is an operation that requires input of characters or the like using the reception unit 70. Examples of the input start operation include an operation of selecting an input field for characters or the like (e.g., a search engine input field, a message input field, a personal information input field, etc.) displayed in the display area 20. Examples of the input start operation include an operation of launching an application that requires input of characters or the like (e.g., a memo pad application, an email application, an SNS (Social Networking Service) application, etc.). Examples of the input start operation include an operation of transitioning an image displayed in the display area 20 to an image that requires input of characters or the like (e.g., a password input screen, etc.).

[0024] If an input start operation is not performed on the image displayed in the display area 20 (NO in step 101), the control unit 50 ends the series of processes.

[0025] On the other hand, if an input start operation is performed on the image displayed in display area 20 (YES in step 101), control unit 50 acquires the detection result output from detection unit 30 (step 102). More specifically, control unit 50 acquires the acceleration of first display area 21 detected by first acceleration sensor 31 and the acceleration of second display area 22 detected by second acceleration sensor 32 as the detection result output from detection unit 30. Then, the control unit 50 obtains the bending angle θ of the display unit 10 and the orientation of the display unit 10 from the obtained acceleration of the first display region 21 and the acceleration of the second display region 22.

[0026] Next, the control unit 50 determines whether the orientation of the display unit 10 acquired in step 102 is the first orientation (step 103). In this embodiment, as described above, the first orientation is the orientation in which the first display area 21 and the second display area 22 are aligned horizontally. The second orientation is the orientation in which the first display area 21 and the second display area 22 are aligned vertically.

[0027] If the orientation of display unit 10 is the first orientation (YES in step 103), control unit 50 determines whether the bending angle θ of display unit 10 is 180° (θ=180°), greater than 90° and less than 180° (90°<θ<180°), greater than 0° and equal to or less than 90°, or greater than 180° and less than 360° (0°<θ≦90°, 180°<θ<360°).

[0028] If it is determined that the bending angle θ of the display unit 10 is 180° (θ = 180° in step 104), the control unit 50 displays the reception unit 70 in the display area 20 of the display unit 10 in a predetermined first manner (step 105). 4 is a diagram showing the accepting unit 70 in the first mode displayed in the display area 20. In FIG. 4, the up-down direction of the figure corresponds to the up-down direction of the image displayed in the display area 20 of the display unit 10.

[0029] 4, the reception unit 70 in the first mode is displayed across the first display region 21 and the second display region 22 of the display region 20. In addition, in the reception unit 70 in the first mode, the area in the display region 20 in which the reception unit 70 is displayed (hereinafter referred to as the display area of ​​the reception unit 70) is approximately 45% of the display region 20. Furthermore, in this example, the reception unit 70 in the first mode has a key arrangement similar to that of a physical keyboard used in a PC (Personal Computer) or the like.

[0030] Here, when the bending angle θ of the display unit 10 is 180°, the user often places the information processing device 1 on a table or the like and operates the display area 20 with both hands, or holds the information processing device 1 in one hand and operates the display area 20 with the other hand. When the bending angle θ of the display unit 10 is 180°, the first display area 21 and the second display area 22 are flat, and the user's operation on the display area 20 is less likely to be obstructed around the bending portion 15. Therefore, in the information processing device 1 of this embodiment, when the bending angle θ of the display unit 10 is 180°, the reception unit 70 is displayed across the first display area 21 and the second display area 22 in the first mode shown in Figure 4, thereby improving the operability of the user's input to the reception unit 70.

[0031] Returning to FIG. 3, if it is determined that the bending angle θ of the display unit 10 is greater than 90° and less than 180° (90°<θ<180° in step 104), the control unit 50 displays the reception unit 70 in the display area 20 of the display unit 10 in a second manner different from the first manner described above (step 106). Here, "different modes" of the reception unit 70 refer to modes in which the operability when the user operates the reception unit 70 is different. The operability refers to the ease of operation of the reception unit 70, which is determined based on criteria such as the ease with which the user's fingers or a touch pen can reach the reception unit 70, and the ease with which the components constituting the reception unit 70 can be touched. Specific examples of modes in which the operability differs include modes in which the display position of the reception unit 70 in the display area 20 of the display unit 10, the display area of ​​the reception unit 70 in the display area 20 of the display unit 10, and at least one of the components constituting the reception unit 70 are different. Note that examples of the components constituting the reception unit 70 include the type, arrangement, and number of keys constituting the reception unit 70.

[0032] Fig. 5 is a diagram showing the accepting unit 70 in the second mode displayed in the display area 20. Fig. 5 shows a case where the bending angle θ of the display unit 10 is 120°. In Fig. 5, the up-down direction of the figure corresponds to the up-down direction of the image displayed in the display area 20 of the display unit 10.

[0033] As shown in FIG. 5, the reception unit 70 in the second mode is displayed divided into a first display region 21 and a second display region 22 of the display region 20. Furthermore, in the reception unit 70 in the second mode, the display area of ​​the reception unit 70 in the display region 20 is smaller than that of the reception unit 70 in the first mode. Furthermore, unlike the reception unit 70 in the first mode, the reception unit 70 in the second mode is displayed at a position away from the bending portion 15. In addition, in the display region 20 shown in FIG. 5, the reception unit 70 is not displayed in the bending portion 15. Furthermore, in this example, the reception unit 70 in the second mode has a key layout in which a physical keyboard is divided into a portion displayed in the first display region 21 and a portion displayed in the second display region 22 (a so-called split keyboard).

[0034] Here, when the bending angle θ of the display unit 10 is equal to or greater than 90° and less than 180°, the user often holds the information processing device 1 with both hands, operates the first display area 21 with the thumb of one hand, and operates the second display area 22 with the thumb of the other hand. In this case, the user's fingers (e.g., thumb) have difficulty reaching the center of the display area 20 close to the bending portion 15. Furthermore, when the bending angle θ of the display unit 10 is equal to or greater than 90° and less than 180°, it is more difficult for the user to insert their fingers into the center of the display area 20 close to the bending portion 15 than when the bending angle θ of the display unit 10 is 180°. For this reason, when the bending angle θ of the display unit 10 is equal to or greater than 90° and less than 180°, the operability of the center of the display area 20 close to the bending portion 15 tends to be reduced.

[0035] In contrast, in the information processing device 1 of this embodiment, when the bending angle θ of the display unit 10 is greater than or equal to 90° and less than 180°, the reception unit 70 is displayed in a second mode in which the display area is smaller than in the first mode and the display position is farther away from the bending portion 15, thereby preventing a decrease in the operability of the user's input to the reception unit 70.

[0036] Returning to Figure 3, if the bending angle θ of the display unit 10 is greater than 0° and less than 90°, or greater than 180° and less than 360° (0°<θ≦90°, 180°<θ<360° in step 104), the control unit 50 displays the reception unit 70 in the display area 20 of the display unit 10 in a third mode different from the first and second modes (step 107). 6(a) and 6(b) are diagrams showing the receiving unit 70 in a third mode displayed in the display area 20. FIG. 6(a) shows a first example of the receiving unit 70 in the third mode, and FIG. 6(b) shows a second example of the receiving unit 70 in the third mode. Note that FIGS. 6(a) and 6(b) show a case where the bending angle θ is 90°. In addition, in FIGS. 6(a) and 6(b), the up-down direction of the diagrams corresponds to the up-down direction of the image displayed in the display area 20 of the display unit 10.

[0037] As shown in FIGS. 6(a) and 6(b), the reception unit 70 in the third mode is displayed in either the first display region 21 or the second display region 22 of the display region 20 (in this example, the first display region 21). In addition, in the reception unit 70 in the third mode, the display area of ​​the reception unit 70 in the display region 20 is smaller than those of the reception unit 70 in the first and second modes. Furthermore, in this example, in the reception unit 70 in the third mode shown in FIG. 6(a), all of the alphabets are arranged in a so-called QWERTY layout. In addition, in the reception unit 70 in the third mode shown in FIG. 6(b), the alphabets are arranged in a numeric keypad layout.

[0038] Here, when the bending angle θ of the display unit 10 is greater than 0° and equal to or less than 90°, or greater than 180° and less than 360°, the user often uses the information processing device 1 while mainly viewing one of the first display area 21 or the second display area 22 and not viewing the other. For example, in the example shown in FIGS. 6(a) and 6(b), the user often mainly views the first display area 21 and does not view the second display area 22. For this reason, it is difficult for the user to operate an area that is difficult for the user to view (second display area 22 in the example shown in FIGS. 6(a) and 6(b)).

[0039] In contrast, in the information processing device 1 of the present embodiment, when the bending angle θ of the display unit 10 is greater than 0° and equal to or less than 90°, or greater than 180° and less than 360°, the receiving unit 70 is displayed in either the first display area 21 or the second display area 22 (first display area 21 in the example shown in FIGS. 6(a)-(b)), so that the receiving unit 70 is less likely to be displayed in an area that is difficult for the user to see (second display area 22 in the example shown in FIGS. 6(a)-(b)). This prevents a decrease in the operability of the user inputting information to the receiving unit 70. Here, the control unit 50 can determine whether to display the reception unit 70 in the first display area 21 or the second display area 22, depending on, for example, the detection results by the detection unit 30, the state of the image displayed in the display area 20, the user's operation on the image displayed in the display area 20, etc.

[0040] Furthermore, when displaying reception unit 70 in the third mode, control unit 50 may be able to change the display position and area of ​​reception unit 70 in first display area 21 or second display area 22 in response to a user operation, etc. In other words, in the third mode, reception unit 70 may be a so-called floating keyboard whose display position and display area in display area 20 are changeable. This makes it possible to display the reception unit 70 in a position in the first display area 21 or the second display area 22 that is easier for the user to operate.

[0041] Returning to FIG. 3, if the orientation of display unit 10 is the second orientation (NO in step 103), control unit 50 determines whether the bending angle θ of display unit 10 is greater than 0° and less than 180° (0°<θ≦180°), or greater than 180° and less than 360° (180°<θ<360°) (step 108).

[0042] If it is determined that the bending angle θ of the display unit 10 is greater than 0° and less than or equal to 180° (0°<θ≦180° in step 108), the control unit 50 displays the reception unit 70 in the display area 20 of the display unit 10 in a fourth mode that is different from the first to third modes described above (step 109). Fig. 7 is a diagram showing the accepting unit 70 in the fourth mode displayed in the display area 20. Note that Fig. 7 shows the case where the bending angle θ of the display unit 10 is 90°.

[0043] 7, the reception unit 70 in the fourth mode is displayed in either the first display region 21 or the second display region 22 of the display region 20 (in this example, the second display region 22). In this example, the reception unit 70 in the fourth mode is displayed over substantially the entire surface of the second display region 22. Furthermore, in this example, the reception unit 70 in the fourth mode has a key arrangement similar to that of a physical keyboard used in a PC or the like.

[0044] Here, when the bending angle θ of the display unit 10 is greater than 0° and equal to or less than 180°, the user often places the information processing device 1 on a table or the like and operates the display area 20 with both hands, or holds the information processing device 1 in one hand and operates the display area 20 with the other hand. In addition, when the bending angle θ of the display unit 10 is greater than 0° and equal to or less than 180°, the user often operates the other of the display areas 20 (in this example, the second display area 22 located on the lower side in the vertical direction of the image) while viewing one of the display areas 20 (in this example, the first display area 21 located on the upper side in the vertical direction of the image).

[0045] In the information processing device 1 of this embodiment, when the bending angle θ of the display unit 10 is greater than 0° and less than or equal to 180°, the reception unit 70 is displayed in the fourth mode shown in Figure 7 over almost the entire surface of one side of the display area 20 (in this example, the second display area 22) that is easier for the user to operate, thereby preventing a decrease in the operability of the user inputting information into the reception unit 70.

[0046] Returning to FIG. 3, if it is determined that the bending angle θ of the display unit 10 is greater than 180° and less than 360° (180°<θ<360° in step 108), the control unit 50 displays the reception unit 70 in the display area 20 of the display unit 10 in a fifth mode, which is different from the first to fourth modes described above (step 110). Fig. 8 is a diagram showing the accepting unit 70 in the fifth mode displayed in the display area 20. Note that Fig. 8 shows a case where the bending angle θ of the display unit 10 is 270°.

[0047] 8, the reception unit 70 in the fifth mode is displayed in either the first display region 21 or the second display region 22 of the display region 20 (in this example, the first display region 21). The reception unit 70 in the fifth mode is displayed in a partial region of the first display region 21 (in this example, the lower half region in the vertical direction of the image). Furthermore, in this example, all of the alphabets in the reception unit 70 in the fifth mode are arranged in a so-called QWERTY layout.

[0048] Here, when the bending angle θ of the display unit 10 is greater than 180° and less than 360°, the user often places the information processing device 1 on a table or the like and operates the display area 20 with both hands, or holds the information processing device 1 in one hand and operates the display area 20 with the other hand. In addition, when the bending angle θ of the display unit 10 is greater than 180° and less than 360°, the user often views and operates only one of the display areas 20 (in this example, the first display area 21 located on the upper side in the vertical direction of the image) and does not use the other (in this example, the second display area 22 located on the lower side in the vertical direction of the image).

[0049] In the information processing device 1 of the present embodiment, when the bending angle θ of the display unit 10 is greater than 180° and less than 360°, the reception unit 70 is displayed in the fifth mode shown in Fig. 8 in a partial region of one of the display areas 20 that the user views and operates (first display area 21 in this example), thereby preventing a decrease in the operability of the user to input to the reception unit 70. Furthermore, by displaying the reception unit 70 in a partial region of one of the display areas 20 that the user views and operates (first display area 21 in this example), it is possible to display another image in the region where the reception unit 70 is not displayed, and even when the other of the display areas 20 (second display area 22 in this example) cannot be viewed, a decrease in the convenience of the information processing device 1 for the user is prevented.

[0050] Returning to FIG. 3, after displaying the reception unit 70 in the display area 20 of the display unit 10 in each mode, the control unit 50 determines whether the user's operation of inputting characters, etc. using the reception unit 70 (hereinafter referred to as the input operation) has been completed (step 111).

[0051] If the input operation has not ended (NO in step 111), control unit 50 returns to step 102 and continues the process. In this case, when the bending angle θ of display unit 10 or the orientation of display unit 10 is changed by a user's operation on information processing device 1, control unit 50 determines the manner (first to fifth manner) in which reception unit 70 is displayed, depending on the bending angle θ of display unit 10 or the orientation of display unit 10 after the change. In other words, after displaying reception unit 70 on display unit 10, if the bending angle θ of display unit 10 or the orientation of display unit 10 is changed, control unit 50 changes the manner in which reception unit 70 is displayed, depending on the bending angle θ of display unit 10 or the orientation of display unit 10 after the change. This makes it possible to set the manner in which reception unit 70 is displayed to be suitable for the state in which the user is using information processing device 1, and thereby suppresses a decrease in operability for the user to input to reception unit 70.

[0052] On the other hand, if the input operation has ended (YES in step 111), the control unit 50 ends the display of the reception unit 70 in the display area 20, and ends the series of processes.

[0053] As described above, in the information processing device 1 of this embodiment, the control unit 50 displays the reception unit 70 in the display area 20 of the display unit 10 in different modes depending on the bending angle θ of the display unit 10 and the orientation of the display unit 10. This prevents a decrease in the operability of inputting information to the receiving unit 70 by the user compared to when the receiving unit 70 is displayed in the same manner regardless of the bending angle θ of the display unit 10 and the orientation of the display unit 10.

[0054] Furthermore, in the information processing device 1 of this embodiment, as described above, when the orientation of the display unit 10 is the first orientation and the bending angle θ of the display unit 10 is 180° or less, the smaller the bending angle θ of the display unit 10, the smaller the display area for displaying the reception unit 70 on the display unit 10. Here, when the bending angle θ of the display unit 10 is 180° or less, the smaller the bending angle θ, the more difficult it is for the user to insert his / her fingers into the center of the display area 20 near the bending portion 15. Therefore, the smaller the bending angle θ, the smaller the area in the display area 20 that is easy for the user to operate.

[0055] In contrast, the smaller the bending angle θ of display unit 10, the smaller the display area for displaying reception unit 70 on display unit 10, making it easier to display reception unit 70 in an area that is easy for the user to operate in display region 20. As a result, it is less likely that there will be any part of reception unit 70 that is difficult for the user to operate, and deterioration in the operability of inputting information into reception unit 70 by the user is further suppressed.

[0056] Furthermore, in the information processing device 1 of this embodiment, as described above, when the orientation of the display unit 10 is the first orientation and the bending angle of the display unit 10 is greater than 90° and less than or equal to 180°, the smaller the bending angle θ of the display unit 10, the farther the reception unit 70 is displayed from the bending portion 15 on the display unit 10. Here, when the bending angle θ of the display unit 10 is 180° or less, the smaller the bending angle θ, the more difficult it is for the user to insert his / her fingers into the center of the display area 20 near the bending portion 15. Therefore, the smaller the bending angle θ, the more difficult it is for the user to operate the reception unit 70 in the area near the bending portion 15.

[0057] In contrast, the smaller the bending angle θ of display unit 10, the farther reception unit 70 is displayed from bending unit 15, thereby preventing reception unit 70 from being displayed in a position that is difficult for the user to operate in display area 20. As a result, the operability of inputting information to reception unit 70 by the user is further prevented from decreasing.

[0058] Furthermore, as described above, information processing device 1 of the present embodiment determines whether or not bending angle θ of display unit 10 falls within a predetermined range, and determines the manner in which reception unit 70 is to be displayed from among the first to fifth manners based on the determination. However, this is not limiting. Control unit 50 may continuously change the manner in which reception unit 70 is displayed, depending on bending angle θ of display unit 10. Specifically, control unit 50 may continuously change at least one of the display position of reception unit 70 in display region 20 of display unit 10, the display area of ​​reception unit 70 in display region 20, and the components constituting reception unit 70, depending on bending angle θ of display unit 10. This allows reception unit 70 to be displayed in a manner more suitable for the bending angle of display unit 10 relative to display region 20 of display unit 10.

[0059] In FIG. 3 and the above-described embodiment, in step 101, it is determined whether a predetermined operation (specifically, an input start operation) has been performed on the image displayed in the display area 20 of the display unit 10 as a predetermined operation on the display unit 10, but this is not limited to this. In step 101, the control unit 50 may determine whether an operation to change the bending angle θ of the display unit 10 has been performed as a predetermined operation on the display unit 10. That is, when an operation to change the bending angle θ of the display unit 10 has been performed, the control unit 50 may display the reception unit 70 in the display area 20 of the display unit 10 according to the bending angle θ of the display unit 10.

[0060] 9(a) to 9(c) are diagrams showing examples of images displayed in the display area 20, and are diagrams for explaining a manner in which the reception unit 70 is displayed in the display area 20 when an operation to change the bending angle θ of the display unit 10 is performed. Fig. 9(a) shows an image displayed before an operation to change the bending angle θ of the display unit 10 (see Fig. 1, etc.) is performed (for example, when the bending angle θ is 180°), and Figs. 9(b) to 9(c) show images displayed after an operation to change the bending angle θ from the state shown in Fig. 9(a) is performed (for example, when the bending angle θ is changed from 180° to 120°).

[0061] A user of the information processing device 1 may change the bending angle θ of the display unit 10 depending on whether the user simply views an image displayed in the display area 20 of the display unit 10 or performs input operations such as entering characters using the reception unit 70 displayed in the display area 20. In the present embodiment, by displaying the reception unit 70 when an operation to change the bending angle θ of the display unit 10 is performed, it becomes possible to display the reception unit 70 in the display area 20, for example, before an input start operation is performed for an image displayed in the display area 20. This makes it possible to quickly display the reception unit 70 in the display area 20 compared to when the reception unit 70 is displayed after an input start operation is performed for an image displayed in the display area 20, and further suppresses a decrease in the operability of the user inputting information into the reception unit 70.

[0062] In the above-described embodiment, the reception unit 70 is displayed in the display area 20 according to the bending angle θ of the display unit 10, regardless of the content of the image displayed in the display area 20. For example, in FIG. 5, when the bending angle θ of the display unit 10 is 120°, the reception unit 70 is displayed in the second mode in which the reception unit 70 is divided into the first display area 21 and the second display area 22, regardless of the content of the image displayed in the display area 20. However, the manner in which the reception unit 70 is displayed in the display area 20 of the display unit 10 may be changed depending on the content of the image displayed in the display area 20 of the display unit 10. Here, the content of the image displayed in the display area 20 may include the type of application that displays the image, the nature of the image (for example, whether the image has a vertical or horizontal viewability, etc.), how to display the characters if the image includes characters (for example, whether the characters are written vertically or horizontally, etc.), the aspect ratio of the image, etc.

[0063] Specifically, in Fig. 9(a), a message screen of an SNS app is displayed in the display area 20. On such a message screen of an SNS app, multiple messages are arranged in order in the vertical direction of the display area 20, making it easy to understand the chronological order of the messages, the senders of the messages, etc. In other words, in Fig. 9(a), images that are easy to view are displayed in the vertical direction of the display area 20. In such a case, if a predetermined operation (for example, an input start operation or an operation of bending the display unit 10) is performed on the display unit 10 and the reception unit 70 is displayed in the second mode shown in Fig. 5, it becomes difficult to display an image that maintains visibility in the up and down directions. In this case, it becomes difficult to grasp the content of the image displayed in the display area 20, which may reduce the convenience of the information processing device 1.

[0064] In contrast, for example, when an image with high visibility in the vertical direction is displayed in the display area 20, the visibility in the vertical direction of the image displayed in the display area 20 can be maintained by displaying the reception unit 70 in either the first display area 21 or the second display area 22. Specifically, as shown in Fig. 9(b), the control unit 50 displays the reception unit 70 in the second display area 22 while displaying an image that maintains vertical visibility in the first display area 21. Alternatively, as shown in Fig. 9(c), the control unit 50 displays the reception unit 70 in the second display area 22 while displaying an image that maintains vertical visibility in the first display area 21 and a portion of the second display area 22. This makes it possible to display the reception unit 70 in the display area 20 while displaying an image that maintains visibility in the up and down directions, thereby preventing a decrease in the convenience of the information processing device 1.

[0065] Furthermore, in the above-described embodiment, after the reception unit 70 is displayed in the display area 20 of the display unit 10, if the bending angle θ of the display unit 10 or the orientation of the display unit 10 changes, the manner in which the reception unit 70 is displayed is changed according to the changed bending angle θ or orientation of the display unit 10, but this is not limited to this.

[0066] For example, if it is not desirable to change the manner in which reception unit 70 is displayed depending on the content of the image displayed in display area 20 of display unit 10, the manner in which reception unit 70 is displayed may be maintained unchanged even when the bending angle θ of display unit 10 or the orientation of display unit 10 changes. This suppresses a decrease in the convenience of reception unit 70 for the user compared to when the manner in which reception unit 70 is displayed is changed depending on the changed bending angle θ or the orientation of display unit 10 regardless of the content of the image displayed in display area 20. Examples of situations in which it is not desirable to change the manner in which the reception unit 70 is displayed include when the reception unit 70 is being used to input text or the like and the display of the reception unit 70 needs to be maintained, or when images other than the reception unit 70 are images that can be viewed in the vertical or horizontal directions and it is not desirable to disrupt this view.

[0067] Furthermore, in the above-described embodiment, the control unit 50 determines the manner in which the reception unit 70 is displayed depending on both the bending angle θ of the display unit 10 and the orientation of the display unit 10. However, for example, the control unit 50 may determine the manner in which the reception unit 70 is displayed depending only on the bending angle θ of the display unit 10, regardless of the orientation of the display unit 10.

[0068] <Program Description> The processing performed by the control unit 50 of this embodiment as described above is prepared as a program such as software, and is realized by the software and hardware resources working together. The program for realizing this embodiment can be provided not only by communication means, but also by being stored on a recording medium such as a CD-ROM.

[0069] In addition, in the above-described embodiments, the term "processor" refers to a processor in a broad sense, and includes general-purpose processors (e.g., CPU: Central Processing Unit, etc.) and dedicated processors (e.g., GPU: Graphics Processing Unit, ASIC: Application Specific Integrated Circuit, FPGA: Field Programmable Gate Array, programmable logic device, etc.). Furthermore, the operations of the processors in the above-described embodiments may be performed not only by a single processor but also by multiple processors located at physically separate locations working together. Furthermore, the order of the operations of the processors is not limited to the order described in the above-described embodiments and may be changed. [Explanation of symbols]
