The functional configuration of the smartphone 1 illustrated in FIG. 1 is an example, and it may be arbitrarily modified within a scope that does not depart from the gist of the disclosure.
An example of the control performed by the smartphone 1 will be explained below with reference to FIG. 2 to FIG. 6. Reference sign F1 displayed in FIG. 2 to FIG. 5 indicates the thumb of a user's right hand. As illustrated in FIG. 2, an example of the control when a so-called home screen is displayed in the display 2A is explained, but the same control can be applied also when the application screen displayed during running of the application is displayed in the display 2A.
FIG. 2 is a diagram of an example of control when the home screen displayed in the display 2A is displayed in a reduced size.
As illustrated in FIG. 2, the smartphone 1 can display a home screen 40a in the display 2A (Step S11). Displayed in the display 2A may be, in addition to the home screen 40a, a so-called quick access area 31, a navigation bar 33, and a status bar 35. Arranged in the quick access area 31 may be icons of applications that the user wants to readily access through the home screen 40a. Arranged in the navigation bar 33 may be a button for executing menu display, a button for executing a predetermined action to the running application, and the like. The status bar 35 may use a numeral, a symbol, an image, a mark, and the like to notify the user of information. The information notified by the status bar 35 may include a remaining mark indicating a remaining amount of a power supply, a radio-wave level mark indicating an electric field strength of radio wave for communication, time, weather, an application running, a type of communication system, a condition of wireless connection, a status of a phone call, a mode of the device, an event occurring in the device, and the like.
In some embodiments, a vertical direction of the display area provided in the display 2A may be determined based on a vertical direction of a character or a vertical direction an image displayed in the display 2A. Therefore, when a long-side direction of the smartphone 1 illustrated in FIG. 2 may be set as a reference, in the display area that the display 2A has, the side where the status bar 35 is displayed is an upper area of the display area, and the side where the quick access area 31 and the navigation bar 33 are displayed is a lower area of the display area. The quick access area 31 and the navigation bar 33 may be displayed in the lower area of the display area in the display 2A.
Subsequently, when detecting an operation of the thumb F1 such that a counterclockwise arc is drawn across the home screen 40a displayed in the display 2A through the touch screen 2B (Step S12), the smartphone 1 displays the home screen 40a displayed in the display 2A in the reduced size (Step S13). When detecting an operation for displaying the home screen 40a in the reduced size, the smartphone 1 invalidates an operation performed on the lower area of the display area where the quick access area 31 and the navigation bar 33 are displayed, in the display area of the display 2A.
When detecting an operation of the thumb F1 that moves over the home screen 40a displayed in the reduced size in a direction in which the status bar 35 is displayed (Step S14), the smartphone 1 displays another home screen 40b on the display 2A (Step S15).
As illustrated in FIG. 2, the smartphone 1 displays the home screen 40a in the reduced size according to the operation of the thumb F1 detected through the touch screen 2B, thus improving the operability at the time of operating the home screen 40a by using only the thumb F1 of the right hand. Accordingly, the smartphone 1 can improve the user's convenience in the case of single-handed operation.
As illustrated in FIG. 2, when detecting the operation of displaying the home screen 40a in the reduced size, the smartphone 1 may invalidate the operation performed on the lower area of the display area where the quick access area 31 and the navigation bar 33 are displayed. This enables the smartphone 1 to prevent an erroneous operation due to a contact of any portion other than the thumb F1 of the right hand to the quick access area 31 and the navigation bar 33. Accordingly, the smartphone 1 can improve the user's convenience in the case of single-handed operation.
When no operation is detected for a certain period of time after the home screen 40a is displayed in the reduced size, the smartphone 1 determines the case as time-out, and may release the reduced display of the home screen 40a and display it in its original size. When detecting an operation performed on any area other than the home screen 40a displayed in the reduced size, in the display area of the display 2A, the smartphone 1 determines the operation as a release operation of the reduced display, and may release the reduced display of the home screen 40a and display it in its original size. The smartphone 1 may release the invalidation of the operation performed on the lower area of the display area where the quick access area 31 and the navigation bar 33 are displayed, in association with the release of the reduced display of the home screen 40a. 
FIG. 3 is a diagram of an example of control when an operation guide for executing processing associated with an icon on the screen displayed in the display 2A is displayed. An example of control when the so-called lock screen is displayed in the display 2A will be explained with reference to FIG. 3.
As illustrated in FIG. 3, the smartphone 1 displays a lock screen 50 in the display 2A (Step S21). Icons A1 to A3 are displayed in the lock screen 50. Activation processing of the mail application 9C is associated with the icon A1. Activation processing of the camera application 9F is associated with the icon A2. Lock release processing is associated with the icon A3. The lock screen 50 is displayed when the smartphone 1 is in a locked state. When the lock screen 50 is displayed in the display 2A, the smartphone 1 does not receive a user operation except a specific operation. The specific operation includes, for example, an operation for releasing the locked state and an operation for executing the processing associated with each of the icons A1 to A3 displayed in the lock screen 50. The locked state may include not only the state of not receiving the user operation but also a security lock state.
Subsequently, when detecting a contact of the thumb F1 to the icon A2 through the touch screen 2B, the smartphone 1 displays an operation guide 50a and an operation guide 50b (step S22). The operation guide 50a and the operation guide 50b guide an operation for activating an application. The operation guide 50a and the operation guide 50b spread from a start point. The start point is a position where the icon A2 is displayed. At this time, the smartphone 1 deletes the display of the icon A1 and the icon A3. The smartphone 1 may display the operation guide 50a and the operation guide 50b while the thumb F1 is in contact to the icon A2, and delete the operation guide 50a and the operation guide 50b when the thumb F1 separates from the icon A2. Alternatively, the smartphone 1 may display the operation guide 50a and the operation guide 50b during a time when a certain period of time elapses even if the thumb F1 separates from the icon A2.
Subsequently, when detecting an operation of moving the thumb F1 from the start point of the operation guide 50a along the operation guide 50a through the touch screen 2B (Step S23), the smartphone 1 deletes the display of the other operation guide 50b. When detecting an operation of moving the thumb F1 to an end point of the operation guide 50a along the operation guide 50a (Step S23), the smartphone 1 activates the camera application 9F and displays a screen 60 of the camera application 9F in the display 2A (Step S24).
At Step S22, the smartphone 1 does not have to delete the display of the icon A1 and the icon A3. At Step S23, the smartphone 1 does not have to delete the display of the other operation guide 50b. 
FIG. 4 is a diagram of an example of control when an assist icon for causing the display 2A to execute a predetermined action is displayed. An example of the control when the so-called home screen is displayed in the display 2A will be explained below with reference to FIG. 4.
As illustrated in FIG. 4, when detecting a contact to a specific area of the display 2A (Step S31), the smartphone 1 displays an image 37, such that a shooting star is falling, and four assist icons B1 to B4 arranged along the image 37 in the display 2A (Step S32). The specific area of the display 2A corresponds to an area on the same side as the side where time and the like are displayed in the status bar 35 and being at a central portion when the smartphone 1 is operated, for example, with one hand using the thumb F1 of the right hand. On the other hand, when the smartphone 1 is operated with one hand using the thumb of the left hand, the specific area corresponds to an area on the opposite side to the side where time and the like are displayed in the status bar 35 and being at a central portion thereof. The smartphone 1 may display only the assist icons B1 to B4 without displaying the image 37.
Minimum conditions required for positions on the display 2A where the assist icons B1 to B4 are displayed are such that, for example, when the smartphone is operated by being held in the right hand, the positions are inside a display area of the display 2A on the side of the thumb F1 of the right hand from a maximum arc that can be drawn counterclockwise on the display 2A by the thumb F1 of the right hand. FIG. 5 is a diagram of an example of an arc capable of being drawn by the thumb F1 of the right hand when the smartphone is operated by being held in the right hand. As illustrated in FIG. 5, when the user operates the smartphone 1 by holding it in the right hand, the smartphone 1 previously measures a maximum arc 38 and a minimum arc 39 capable of being drawn by the thumb F1 of the right hand. The smartphone 1 determines the display positions of the assist icons B1 to B4 within the display area of the display 2A sandwiched between the maximum arc 38 and the minimum arc 39. It is most preferable that the smartphone 1 determines the display positions of the assist icons B1 to B4 within an area sandwiched between the maximum arc 38 and the minimum arc 39 and along an arc of which distances from the maximum arc 38 and the minimum arc 39 are even.
The assist icons B1 to B4 are previously associated with respective predetermined actions. Information related to a correlation between the assist icons B1 to B4 and the predetermined actions or functions executed according to each operation performed on the assist icons B1 to B4 is included in the setting data 9Z. FIG. 6 is a diagram of an example of a correlation between the assist icons B1 to B4 and the predetermined actions executed corresponding to each operation performed on the assist icons B1 to B4. As illustrated in FIG. 6, an action of memory release is associated with the assist icon B1. An action of displaying a notification screen is associated with the assist icon B2. The notification screen is a screen including a notification area to notify the user of detailed information of information for an application executed in the background to be notified to the status bar 35. An action of returning to previous one (going back to the beginning) is associated with the assist icon B3. The “return to previous one” means that during running of the application, the step is returned to the previous state before an input command is executed. An action of menu display is associated with the assist icon B4. The menu display is a display of a list of general operation items such as various settings for the smartphone 1 and a search of various data stored in the storage 9.
Subsequently, when detecting an operation performed on the assist icon 2B through the touch screen 2B (Step S33), the smartphone 1 displays a notification screen 70 on the display 2A as the action associated with the assist icon 2B (Step S34).
For example, when the operation for displaying the notification screen is associated with a swipe from an upper end of the display 2A where the status bar 35 is displayed to a lower end thereof, it is difficult for the user to display the notification screen on the display 2A by the operation using only the thumb F1 of the right hand. Therefore, the actions difficult to be executed by the operation using only the thumb F1 of the right hand are previously associated with the assist icons B1 to B4. Then as illustrated in FIG. 4, the smartphone 1 displays the assist icons B1 to B4 at positions where operations are easily performed by the thumb F1. This enables the user to easily display the notification screen even by an operation using only the thumb F1 of the right hand. In this way, the smartphone 1 allows improvement of the user's convenience in the case of single-handed operation.
In an example illustrated in FIG. 4, the smartphone 1 determines time-out when no operation is detected for a certain period of time after the display of the assist icons B1 to B4, and may delete the image screen 37 and the assist icons B1 to B4 from the home screen 40a. 
In an example illustrated in FIG. 4, when detecting an operation performed on a specific area of the home screen 40a, the smartphone 1 may invalidate the operation performed on the lower area of the display area where the quick access area 31 and the navigation bar 33 are displayed. In this case, it is difficult for the user to operate menu display buttons arranged in the navigation bar 33 using only the thumb F1 of the right hand. Therefore, the smartphone 1 associates the menu display with the assist icons. As illustrated in FIG. 4, in the smartphone 1, the assist icons are displayed at the positions where the operation using the thumb F1 is easily performed. The user can thereby easily perform the menu display even with the operation using only the thumb F1 of the right hand. In this way, the smartphone 1 allows improvement of the user's convenience in the case of single-handed operation.
The conditions of invalidating the operation performed on the lower area of the display area where the quick access area 31 and the navigation bar 33 are displayed are not limited to the case where the operation for displaying the home screen 40a in the reduced size is detected and to the case where the operation performed on a specific area of the home screen 40a is detected. For example, during running of an application, the operation performed on the lower area of the display area where the quick access area 31 and the navigation bar 33 are displayed may be invalidated according to the detection of an operation performed on a specific area of the display 2A.
An example of a processing procedure performed by the smartphone 1 will be explained below with reference to FIG. 7 to FIG. 9. The processing procedure illustrated in FIG. 7 to FIG. 9 is implemented by the controller 10 executing the control program 9A or the like stored in the storage 9.
FIG. 7 is a flowchart of a processing procedure when the screen displayed in the display 2A is displayed in a reduced size.
As illustrated in FIG. 7, the controller 10 determines whether a predetermined operation has been detected through the touch screen 2B (Step S101). When it is determined that a predetermined operation has not been detected (No at Step S101), the controller 10 ends the processing procedure illustrated in FIG. 7.
Meanwhile, when it is determined that a predetermined operation has been detected (Yes at Step S101), the controller 10 displays the screen displayed in the display 2A in the reduced size (Step S102). The screen displayed in the display 2A includes the home screen 40a. 
Subsequently, the controller 10 invalidates the operation performed on the predetermined area in the display area of the display 2A (Step S103). The controller 10 invalidates the operation performed on the so-called quick access area 31 and the navigation bar 33 (see FIG. 2, etc.)
The controller 10 then determines whether the time-out has occurred or the release operation of the reduced display has been performed (Step S104). The controller 10 determines time-out when no operation is detected for a certain period of time after the display of the screen in the reduced size at Step S102. When detecting an operation performed on any area other than the screen displayed in the reduced size in the display area of the display 2A, the controller 10 determines that it is the release operation of the reduced display.
When it is determined that the time-out has not occurred or the release operation of the reduced display has not been performed (No at Step S104), the controller 10 repeatedly performs the determination of Step S104.
Meanwhile, when it is determined that the time-out has occurred or the release operation of the reduced display has been performed (Yes at Step S104), the controller 10 displays the screen displayed in the display 2A in the original size (Step S105).
Subsequently, the controller 10 releases the invalidation of the operation performed on the predetermined area of the display 2A (Step S106), and ends the processing procedure illustrated in FIG. 7.
FIG. 8 is a flowchart of a processing procedure when the operation guide is displayed on the screen displayed in the display 2A.
As illustrated in FIG. 8, the controller 10 determines whether a contact to an icon on the screen displayed in the display 2A has been detected through the touch screen 2B (Step S201). When it is determined that a contact to an icon on the screen has not been detected (No at Step S201), the controller 10 ends the processing procedure illustrated in FIG. 8.
Meanwhile, when it is determined that a contact to an icon on the screen has been detected (Yes at Step S201), the controller 10 displays the operation guide (see FIG. 3) on the screen (Step S202).
Subsequently, the controller 10 determines whether an operation following the operation guide has been detected through the touch screen 2B (Step S203).
When it is determined that an operation following the operation guide has been detected (Yes at Step S203), the controller 10 executes the processing associated with the icon where the contact is detected at Step S201 (Step S204), and ends the processing procedure illustrated in FIG. 8.
Meanwhile, when it is determined that an operation following the operation guide has not been detected (No at Step S203), the controller 10 determines whether a contact to the icon on the screen is no longer detected (non-detection has been obtained) (Step S205).
When it is determined that a contact to the icon on the screen has been detected (No at Step S205), the controller 10 repeatedly performs the determination of Step S205.
Meanwhile, when it is determined that a contact to the icon on the screen is no longer detected (Yes at Step S205), the controller 10 deletes the operation guide from the screen (Step S206), and ends the processing procedure illustrated in FIG. 8.
FIG. 9 is a flowchart of a processing procedure when the assist icon is displayed on the screen displayed in the display 2A.
As illustrated in FIG. 9, the controller 10 determines whether a contact to a specific area of the display 2A has been detected through the touch screen 2B (Step S301). The specific area of the display 2A corresponds to an area on the same side as the side where time and the like are displayed in the status bar 35 and being at a central portion when the smartphone 1 is operated, for example, with one hand using the thumb F1 of the right hand. When it is determined that a contact to a specific area has not been detected (No at Step S301), the controller 10 ends the processing procedure illustrated in FIG. 9.
Meanwhile, when it is determined that a contact to a specific area has been detected (Yes at Step S301), the controller 10 displays an assist icon (see FIG. 4) on the screen displayed in the display 2A (Step S302).
Subsequently, the controller 10 determines whether an operation performed on the assist icon has been detected through the touch screen 2B (Step S303).
When it is determined that an operation performed on the assist icon has been detected (Yes at Step S303), the controller 10 executes the action associated with the assist icon (Step S304), and ends the processing procedure illustrated in FIG. 9.
Meanwhile, when it is determined that an operation performed on the assist icon has not been detected (No at Step S303), the controller 10 determines whether the time-out has occurred (Step S305). The controller 10 determines that the time-out has occurred when no operation is detected for a certain period of time after the display of the assist icon.
When it is determined that the time-out has not occurred (No at Step S305), the controller 10 repeatedly performs the determination of Step S305.
Meanwhile, when it is determined that the time-out has occurred (Yes at Step S305), the controller 10 deletes the assist icon from the screen (Step S306), and ends the processing procedure illustrated in FIG. 9.
In an example illustrated in FIG. 2, the controller 10 may move the home screen 40a displayed in the reduced size in anyone of directions in the display area of the display 2A, to be display in this location. FIG. 10 is a diagram of a display example of the reduced screen. As illustrated in FIG. 10, when the user operates the smartphone 1 with the right hand, the controller 10 may move the reduced home screen 40a in a lower right direction, to be displayed in this location. The side where the status bar 35 is displayed is set as an upper side, and the side where the time and the like are displayed in the status bar 35 is set as a right side. For example, the controller 10 determines whether an operation is right-handed operation or left-handed operation based on the operation for displaying the home screen 40a in the reduced size (e.g., Step S12 in FIG. 2), moves the reduced home screen 40a to the lower right side to be displayed if it is the right-handed operation, and moves the reduced home screen 40a to the lower left side to be displayed if it is the left-handed operation. The controller 10 determines that the operation is the right-handed operation if it draws an arc counterclockwise, and determines that the operation is the left-handed operation if it draws an arc clockwise.
In an example illustrated in FIG. 4, when the application is running, it may be configured that the controller 10 displays an assist icon associated with an action, a function, or processing, etc. for supporting the operation of the application running. For example, when the mail application 9C is running, the controller 10 displays an assist icon associated with an action related to execution of the mail application 9C such as composition, transmission, draft, or the like of a mail.
When the application, used by inclining a longitudinal direction of the smartphone 1 to horizontal, is running, the controller 10 may determine an upper direction of a character, graphics, a symbol, and an image in the application screen displayed in the display 2A and a direction in which a reduced application screen is moved based on the determination result of the attitude detecting module 15 or the like. For example, the controller 10 refers to information for a previously registered dominant hand of the user to move the reduced application screen to the dominant hand side and displays it in this location based on the determination result of the attitude detecting module 15 or the like.
