Japanese Patent Application Publication No. 2015-170050

In the drawing device described in Patent Document 1, when an item is scroll-displayed while being dragged, part of the drawing area is deleted during the dragging operation in order to suppress storage capacity. Therefore, if the drawing area to which the operation target item belongs is deleted, there is a problem in that the operation target item disappears during the drag operation.

The problem to be solved by the present invention is to provide an information processing method, an information processing device, and a program that prevent an item to be operated during a drag operation from disappearing even if a page is deleted to reduce storage capacity. It is to provide.

The present invention stores a first page, a second page provided next to one side of the first page, and a third page provided next to the other side of the first page, together with items belonging to each page. An operation on the first page stored in the device and displayed on the touch panel display is detected, and the operation on the first page is an operation of scrolling from the first page to the second page while dragging an item on the first page. In this case, the page displayed on the touch panel display is changed from the first page to the second page while the item is displayed, and the item's affiliation is changed from the first page to the second page before the drop operation is performed on the item. The above problem is solved by changing the number of pages to two and deleting the third page from the storage device.

According to the present invention, even if a page is deleted to reduce storage capacity, it is possible to prevent an item to be operated during a drag operation from disappearing.

Embodiments of an information processing method, an information processing device, and a program according to the present invention will be described below based on the drawings.

FIG. 1 is a schematic diagram of the configuration of a navigation device 100 according to this embodiment. The navigation device 100 is a device that is installed inside a vehicle and provides vehicle route guidance to an occupant. As shown in FIG. 1, the navigation device 100 includes a display 1, a storage device 2, and an information processing device 10.

The display 1 is a touch panel type display, and is mounted on a vehicle. The touch panel type display 1 is equipped with a pressure sensor, and detects the pressing force applied to the display 1 during a touch operation from a resistance value, voltage, etc. The mechanism of the pressure-sensitive sensor is not particularly limited, and any pressure-sensitive sensor mechanism known at the time of filing can be used as appropriate. Further, the touch panel is not limited to a pressure-sensitive type, and may be of other types such as an electrostatic type. The display 1 may be a touch panel type display 1, and the type of the display 1 is not particularly limited. The display 1 may be a liquid crystal display or an organic electro-luminescence (OEL) display.

For example, the display 1 is placed on a dashboard between a driver's seat and a passenger's seat. Further, the display 1 is disposed in front of the driver's seat and the front passenger's seat so that the driver sitting in the driver's seat and the passenger sitting in the front passenger's seat (hereinafter referred to as front passenger) can reach the display 1. A driver or a passenger in the passenger seat inputs operation details for the navigation device 100, which will be described later, into the display 1. The touch operation is an operation of touching an item displayed on the display 1 with a finger or the like. Examples of items include icons, buttons, and the like. Touch operations include tap (touching the screen once), double tap (touching the screen twice), long tap (pressing and holding the screen), and swipe (sliding the finger that touched the screen on the screen). (trace your finger)), flick (move the finger that touched the screen in a quick flicking motion), pinch in/pinch out (touch the screen with two fingers and move them closer/away) , Drag (hold down an item on the screen and slide it), Drop (hold down an item with your finger and then release it from the screen), Scroll (without taking your finger off the screen, (moving your finger up and down or left and right on the screen). Note that the touch operation may be so-called hovering, in which a finger or the like is brought close to the display screen, without directly touching the display screen of the display 1. Note that the touch operation method is not limited to these, and other methods may be used.

When the driver or the front passenger performs a touch operation on the display 1, the display 1 detects the position of the touch operation on the display screen and outputs information on the detected position to the information processing device 10. Further, the display 1 outputs the position of the touch operation as well as the detection result by the pressure-sensitive sensor to the information processing device 10 . On the other hand, a control command for displaying image data is input to the display 1 from the information processing device 10 . The display 1 displays one or more screens based on image data.

The storage device 2 is a storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive). The storage device 2 stores various data regarding the navigation device 100. Furthermore, the storage device 2 outputs stored data to the information processing device 10 in response to a control command from the information processing device 10. The storage device 2 also deletes data, updates existing data, stores new data, etc. in response to control commands from the information processing device 10.

Here, the structure of data stored in the storage device 2 will be explained using FIG. 2. FIG. 2 is a diagram for explaining the structure of data stored in the storage device 2. As shown in FIG. FIG. 2(A) is a diagram for explaining the relationship between pages displayed on the display 1 and scroll operations, and FIG. 2(B) is a diagram for explaining the data structure of each page shown in FIG. 2(A). This is a diagram for

In the example of FIG. 2(A), page A is displayed on the display 1. For example, when page A is displayed on display 1 immediately after starting navigation device 100, page A is a page equivalent to the home screen of navigation device 100. In the example of FIG. 2(A), items A1 to A4 are arranged in the upper row of page A from left to right when viewed from the front, and items A5 to A8 are arranged from left to right in the lower row of page A. It is located. Items A1 to A8 are icons and buttons for realizing the functions of the navigation device 100. In the present embodiment, the functions of the navigation device 100 are not particularly limited, but examples of items A1 to A8 include a "home" button for searching for a driving route to home based on a home address registered in advance. can.

Each of item A1 to item A8 is a plurality of components necessary for displaying on display 1. The multiple components include image information representing the image displayed on the display 1, character information representing the characters displayed on the display 1, coordinate information representing the display position on the display 1, and sizes of each of the images and characters. It includes dimension information representing the item, and movement information representing the movement when the item is touched. Taking the case of the above "home" button as item A1 as an example, the image information of item A1 is an image representing a house, the text information of item A1 is the text "home", and the coordinates of item A1 are The information is the first position from the left in the upper row when viewed from the front, the dimension information of item A1 is the image size of the image representing the house and the font size of "home", and the operation information of item A1 is registered in advance. This is information for a search process that searches for a driving route to one's home based on the home information provided.

Further, as shown in FIG. 2(A), when page A is displayed on the display 1, a page B that is not displayed on the display 1 is provided next to the right side of the page A when viewed from the front, and a page B that is not displayed on the display 1 is provided on the left side of the page A when viewed from the front. A Z page that is not displayed on the display 1 is provided next to it. In FIG. 2A, each page is shown for convenience in order to explain the scrolling operation to page B or page Z. A scroll operation is required to display page B on display 1, and when a scroll operation is performed from page A to page B, the page displayed on display 1 is changed to page A by the information processing device 10, which will be described later. is changed to page B. Similarly, a scroll operation is required to display page Z on display 1, and when a scroll operation is performed from page A to page Z, the page displayed on display 1 is , the A page is changed to the Z page.

For example, assume that the page displayed on the display 1 is changed from page A to page B by a scroll operation. In this case, a B page is displayed on the display 1, in which items B1 to B4 are arranged from left to right when viewed from the front in the upper row, and items B5 to B8 are arranged from left to right when viewed from the front on the lower row. . Further, for example, assume that the page displayed on the display 1 is changed from page A to page Z by a scroll operation. In this case, a B page is displayed on the display 1, in which items Z1 to Z4 are arranged in the upper row from left to right in front view, and items Z5 to Z8 are arranged in the lower row from left to right in front view. .

As shown in FIG. 2(B), when the A page is displayed on the display 1, the storage device 2 stores the A page, the B page provided next to the right side of the A page when viewed from the front, and the A page when viewed from the front. The Z page provided next to the left side is memorized. In addition to each page, the storage device 2 stores items A1 to A8 as items attached to page A, items B1 to B8 as items attached to page B, and items Z1 to Z8 as items attached to page Z. Remember. The relationship between pages and items can also be expressed as Items A1 to A8 are under Page A, Items B1 to B8 are under Page B, and Items Z1 to Z8 are under Page Z. can. In this embodiment, the storage device 2 stores the display target page displayed on the display 1, the page provided next to the right side of the display target page (also referred to as the right-hand side page), and the left side of the display target page when viewed from the front. Data for three pages of the page provided next to the page (adjacent page on the left) is stored. The information processing device 10, which will be described later, outputs to the storage device 2 a control command for storing three pages of data in accordance with the scroll operation.

Returning to FIG. 1, the configuration of the navigation device 100 will be described. The information processing device 10 is composed of a computer equipped with hardware and software, and specifically includes a ROM (Read Only Memory) that stores programs, and a CPU (Central Processing Unit) that executes the programs stored in the ROM. ) and a RAM (Random Access Memory) that functions as an accessible storage device 2. Note that as an operating circuit, an MPU (Micro Processing Unit), a DSP (Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), etc. can be used instead of or in addition to the CPU. . The controller 11 shown in FIG. 1 is a main body that executes an information processing method according to the present invention, which will be described later, and corresponds to a computer.

In this embodiment, a configuration in which a program to be executed by the information processing device 10 is stored in advance in the ROM will be described as an example, but the location where the program is stored is not limited to the ROM. For example, the program can be read by a computer and may be stored in a portable computer-readable recording medium (eg, disk media, flash memory, etc.). In this case, the information processing device 10 downloads a program from a computer-readable recording medium and executes the downloaded program. In other words, the information processing device 10 may be configured to include only an operating circuit and download the program from outside.

As shown in FIG. 1, the controller 11 of the information processing device 10 includes an operation detection section 12, an item management section 13, a page management section 14, and a display control section 15 as functional blocks.

The operation detection unit 12 detects a touch operation performed on the display 1 based on information input from the display 1. The operation detection unit 12 receives input from the display 1 of the touch-operated position information on the display 1 and the detection results of the pressure sensor (resistance value, voltage, etc. indicating the pressing force). For example, the operation detection unit 12 determines whether the operation on the display 1 is a tap operation, a double tap operation, a long tap operation, a swipe operation, a flick operation, a pinch-in/pinch-out operation, or a drag operation based on information input from the display 1. , a drop operation, and a scroll operation. Note that the number of touch operations detected by the operation detection unit 12 is not particularly limited; for example, the operation detection unit 12 detects that the touch operations on the display 1 are two types of touch operations: a drag operation and a scroll operation. You may. As a method for detecting a touch operation by the operation detection unit 12, a known detection method known at the time of filing of this application can be used.

The item management unit 13 manages items stored in the storage device 2 according to the touch operation detected by the operation detection unit 12. For example, when the operation detection unit 12 detects a drag operation, the item management unit 13 identifies the operated item on the display 1 as the target of the drag operation. Furthermore, when the location of an item is changed on the same page by a drag operation or a drop operation, the item management unit 13 updates the position information of the item on the page and issues a control command for updating the position information of the item. Output to storage device 2. As a result, the position information of the item on the page stored in the storage device 2 is updated.

The page management unit 14 manages pages stored in the storage device 2 according to touch operations detected by the operation detection unit 12. For example, when the operation detection unit 12 detects a scroll operation, the page management unit 14 identifies the scroll destination page. Furthermore, when the operation detection unit 12 detects a scroll operation, the page management unit 14 generates a new page as a new page. Furthermore, the page management unit 14 outputs to the storage device 2 a control command for deleting the existing page stored in the storage device 2 and storing a new page. Thereby, the storage device 2 deletes the existing page according to the control command and stores the new page. Although the processing order of the new page generation process and the existing page deletion process is not particularly limited, in this embodiment, the page management unit 14 deletes the existing page after generating the new page. Note that the page management unit 14 may generate a new page after deleting an existing page, or may delete an existing page and generate a new page at the same time.

The processing of the page management unit 14 when a scroll operation is performed will be described using FIG. 2(A). In the example of FIG. 2A, when the operation detection unit 12 detects a scroll operation from page A to page B, the page management unit 14 identifies page B as the scroll destination page. Next, the page management unit 14 generates a C page (see FIG. 5B) and each item belonging to the C page next to the B page on the side opposite to the side where the A page is provided. At this time, the page management unit 14 generates a C page based on the data structure (also referred to as a software instance) of the Z page to be deleted. For example, the page management unit 14 applies the position information and size information of each item belonging to the Z page to the position information and size information of each item belonging to the C page. As a result, the position information and dimension information of each item belonging to the C page can be set by reusing the position information and dimension information of each item belonging to the Z page, so the process of setting the position information and dimension information is simplified. It is possible to prevent new execution, improve calculation speed, and reduce calculation load. Here, the difference between a new generation process that generates a new page without using an existing page and a reuse process that generates a new page by reusing an existing page will be explained. When the page management unit 14 executes the new generation process, first, for each item, it generates a software instance that includes position information and dimension information of the item. Next, the page management unit 14 adds the above-mentioned image information, character information, and operation information to each software instance. As a result, a new page with multiple items attached is generated without using an existing page. When adding image information, character information, and operation information to a software instance, the order of the software instances to which each piece of information is added is not particularly limited. On the other hand, when the page management unit 14 executes the reuse process, unlike the new generation process, it does not generate a software instance. The page management unit 14 adds image information, character information, and operation information to software instances that constitute existing pages. That is, when the page management unit 14 executes the reuse process, it adds image information, text information, and operation information to each software instance of the existing page. As a result, a new page to which a plurality of items are attached is generated using the position information and dimension information of each item belonging to the existing page. Note that the above-described new generation process and reuse process are just examples, and the page management unit 14 can use any of the known processes known at the time of filing of this application. In the case of the above example, the page management unit 14 generates the C page and each item belonging to the C page using the software instance of the Z page scheduled to be deleted by executing the reuse process.

When the page management unit 14 generates the C page and the items belonging to the C page, it outputs to the storage device 2 a control command for deleting the Z page and the items belonging to the Z page stored in the storage device 2 . Thereby, the storage device 2 deletes the Z page and the items belonging to the Z page. The page management unit 14 also outputs a control command to the storage device 2 for causing the storage device 2 to store the C page and the items belonging to the C page. Thereby, the storage device 2 stores the C page and the items attached to the C page. In this example, before the scroll operation was performed, the storage device 2 had stored page A displayed on the display 1, page B as the adjacent page on the right, and page Z as the adjacent page on the left. When a scroll operation is performed, the storage device 2 stores page B displayed on the display 1, page C as the right-hand adjacent page of page B, and page A as the left-hand adjacent page of page B.

The display control unit 15 controls the screen display of the display 1 according to the touch operation detected by the operation detection unit 12, the item management process by the item management unit 13, and the page management process by the page management unit 14. In the case of the example shown in FIG. 2A, the display control unit 15 detects a scroll operation from page A to page B by the operation detection unit 12, and specifies page B as the scroll destination page by the page management unit 14. Then, a control command for changing the display from page A to page B is output to the display 1. Thereby, the page displayed on the display 1 is changed from page A to page B in accordance with the scroll operation. For example, when the operation detection unit 12 detects a drag operation on item A1 on page A and the item management unit 13 specifies item A1 as the item to be dragged, the display control unit 15 performs a drag operation on the item A1. Accordingly, a control command for moving item A1 is output to display 1. Thereafter, when the operation detection unit 12 detects a drop operation on the item A1, the display control unit 15 outputs a control command to the display 1 to display the item A1 at the position where the drop operation was performed. Thereby, the display position of item A1 is changed to a position corresponding to the drag operation and drop operation.

Next, an information processing method executed by the controller 11 will be described using FIG. 3. FIG. 3 is an example of a flowchart showing the procedure of information processing according to this embodiment. Each process in the flowchart of FIG. 3 is executed by the controller 11. Further, after finishing the process in the flowchart of FIG. 3, the controller 11 starts the process in step S1 after a predetermined period and repeatedly executes the process in the flowchart of FIG.

In step S1, the controller 11 outputs to the display 1 a control command for displaying page n out of page n-1, page n, and page n+1 stored in the storage device 2. The display 1 displays page n and items belonging to the page n based on control commands (including image data) input from the controller 11 . Note that n is an integer.

In step S2, the controller 11 detects a touch operation on the display target page (n page). The controller 11 determines the type of touch operation based on information input from the display 1.

In step S3, the controller 11 determines whether the operation on the display target page (n page) is a scroll operation from page n while dragging a specific item on page n, based on the processing result in step S2. Determine whether or not. If the controller 11 makes a positive determination, the process proceeds to step S4, and if the controller 11 makes a negative determination, the process proceeds to step S13.

If a negative determination is made in step S3, the process advances to step S13. In step S13, the controller 11 executes display control on the display 1 in response to the operation on page n based on the processing result in step S2. For example, when the operation on the display 1 is a scroll operation, the controller 11 outputs to the display 1 a control command for changing the page displayed on the display 1 from page n to the scroll destination page. When the process in step S13 ends, the controller 11 ends the process in the flowchart shown in FIG.

On the other hand, if an affirmative determination is made in step S3, the process advances to step S4. In step S4, the controller 11 specifies the page to be scrolled from page n based on the processing result in step S2. For example, the controller identifies the page to scroll to based on the position of the item to be dragged. If the item to be dragged on page n is located at the end of page n+1, the controller specifies the scroll destination page as page n+1. On the other hand, if the item to be dragged on page n is located at the end of page n-1, the controller specifies the scroll destination page as page n-1. If page n+1 is specified as the scroll destination page, the process proceeds to step S5, and if page n-1 is specified as the scroll destination page, the process proceeds to step S9.

If page n+1 is specified as the scroll destination page in step S4, the process advances to step S5. In step S5, the controller 11 outputs a control command to the display 1 to change the display from page n to page n+1. Thereby, the display 1 changes the display target page from page n to page n+1 in response to the scrolling operation while dragging.

In step S6, the controller 11 generates page n+2 next to the display target page (n+1 page) after the scroll operation on the opposite side to the side where the display target page (n page) before the scroll operation is provided. do. For example, the controller 11 generates page n+2 by applying the position information and size information of each item belonging to page n-1 to the position information and size information of each item belonging to page n+2. When the controller 11 generates the n+2 page, it outputs a control command for storing the n+2 page to the storage device 2. As a result, the storage device 2 stores the n+2 page generated as a new page.

In step S7, the controller 11 changes the affiliation of the item to be dragged from the display target page (n page) before the scroll operation to the display target page (n+1 page) after the scroll operation. In other words, the controller 11 forcibly moves the affiliation of the item to be dragged to the display target page so as to correspond to the display target page.

In step S8, the controller 11 outputs a control command for deleting page n-1 to the storage device 2. As a result, the storage device 2 deletes page n-1 and the items belonging to page n-1. When the process in step S8 ends, the controller 11 ends the process in the flowchart shown in FIG.

If page n-1 is specified as the scroll destination page in step S4, the process advances to step S9. In step S9, the controller 11 outputs to the display 1 a control command for changing the display from page n to page n-1. Thereby, the display 1 changes the display target page from page n to page n-1 in response to the scrolling operation while dragging.

In step S10, the controller 11 sets n-2 next to the display target page (n-1) after the scroll operation on the opposite side to the side where the display target page (n page) before the scroll operation is provided. Generate the page. For example, the controller 11 generates page n-2 by applying the position information and size information of each item belonging to page n+1 to the position information and size information of each item belonging to page n-2. After generating the n-2 page, the controller 11 outputs a control command for storing the n-2 page to the storage device 2. As a result, the storage device 2 stores the generated n-2 pages.

In step S11, the controller 11 changes the affiliation of the item to be dragged from the page to be displayed (page n) before the scroll operation to the page to be displayed after the scroll operation (page n-1).

In step S12, the controller 11 outputs a control command for deleting page n+1 to the storage device 2. As a result, the storage device 2 deletes the n+1 page and the items belonging to the n+1 page. When the process in step S12 ends, the controller 11 ends the process in the flowchart shown in FIG.

Note that when the controller 11 executes the process of the flowchart shown in FIG. 3 again after the process of the flowchart shown in FIG. 3 is finished, the page in each step is updated according to the page stored in the storage device 2. As an example, a case will be described in which the process of the flowchart shown in FIG. 3 is completed through steps S1 to S8, and the controller 11 executes the process of the flowchart shown in FIG. 3 again. In this example, the storage device 2 stores a page to be displayed (n+1 page), an adjacent page on the right (n+2 page), and an adjacent page on the left (n page). Therefore, in step S1, the controller 11 outputs to the display 1 a control command for displaying page n+1 among pages n, page n+1, and page n+2 stored in the storage device 2. In subsequent steps as well, the controller 11 executes processes corresponding to page n, page n+1, and page n+2 stored in the storage device 2. As another example, assume that the process of the flowchart shown in FIG. 3 is completed through steps S1 to S4 and S9 to S12, and the controller 11 executes the process of the flowchart shown in FIG. 3 again. List and explain. In this example, the storage device 2 stores a page to be displayed (page n-1), an adjacent page on the right (n page), and an adjacent page on the left (page n-2). Therefore, in step S1, the controller 11 outputs to the display 1 a control command for displaying page n-2, page n-1, and page n-1 of n pages stored in the storage device 2. do. In the subsequent steps as well, the controller 11 executes processes corresponding to page n-2, page n-1, and page n stored in the storage device 2.

Next, a comparative example will be given to explain problems that may occur when pages are deleted to reduce the capacity of the storage device 2. The information processing apparatus according to the comparative example differs from the information processing apparatus 10 according to the present embodiment in that it does not have a function of changing the affiliation of the item to be dragged, but the other functions are different from the information processing apparatus 10 according to the present embodiment. It is assumed that the information processing device 10 has the same functions as the information processing device 10.

FIGS. 4 and 5 are diagrams for explaining processing executed by the information processing apparatus according to the comparative example when a scroll operation is performed while dragging. FIG. 4 is a diagram for explaining screen transition according to a comparative example when a scroll operation is performed while dragging. FIG. 5 is a diagram for explaining processing of an information processing apparatus according to a comparative example.

[1] (Comparative example) Scroll operation from page A to page B while dragging item A8 From the state where page A is displayed on display 1 (Figure 4 (A)), scroll item A8 on page A separately. In order to place the item on the page, the driver or front passenger presses and holds the item A8 with a finger (FIG. 4(B)) and slides the item A8 to the right end of the A page (FIG. 4(C)). In the scenes shown in FIGS. 4(A) to 4(C), the information processing apparatus according to the comparative example specifies item A8 as the item to be dragged, as shown in FIG. is slid to the right end of page A, and a scroll operation from page A to page B is detected. Further, as shown in FIG. 5B, the information processing apparatus according to the comparative example creates page C next to page B, which is the scroll destination, on the opposite side to the side where page A is provided. The information processing device according to the comparative example deletes the Z page and the items belonging to the Z page from the storage device 2, and stores the C page in the storage device 2. As a result, as shown in FIG. 5C, in the comparative example, the storage device 2 stores pages A to C and items belonging to each page.

[2] (Comparative example) Scroll operation from page B to page C while dragging item A8 After the screen transition from page A to page B (Figure 4 (D)), page B appears on display 1. Is displayed. With the B page displayed on the display 1, the driver or the front passenger holds the item A8 with a finger and maintains the position of the item A8 at the right end of the B page (FIG. 4(E)). In the scene shown in FIG. 4(E), the information processing device according to the comparative example specifies item A8 as the item to be dragged, and the position of item A8 is on page B, as shown in FIG. 5(C). A slide operation from page B to page C is detected by maintaining it at the right end. Furthermore, as shown in FIG. 5D, the information processing apparatus according to the comparative example creates page D next to page C, which is the scroll destination, on the opposite side to the side where page B is provided. The information processing device according to the comparative example deletes the A page and the items belonging to the A page from the storage device 2, and stores the D page in the storage device 2. As a result, as shown in FIG. 5E, in the comparative example, the storage device 2 stores pages B to D and items belonging to each page.

In the information processing device according to the comparative example, in response to a scroll operation, the affiliation of item A8 that is the target of a drag operation is not changed. , item A8 to be dragged is also deleted from the storage device 2 (FIG. 5(D)). Therefore, on the screen of display 1, after the screen transitions from page B to page C (FIG. 4(F)), a problem arises in that the item A8 to be manipulated disappears from the screen during the drag operation (FIG. 4(F)). 4(G)).

In step S13, the controller 11 specifies item A8 as the item to be dragged, and specifies page B as the scroll destination page. Then, the controller 11 outputs a control command to the display 1 to change the display from page A to page B.

In step S14, the controller 11 generates page C next to page A, which is the scroll destination, on the side opposite to the side where page B is provided. In step S15, the controller 11 changes the affiliation of the item A8 targeted for the drag operation from the A page to the B page. In step S16, the controller 11 outputs a control command to delete the Z page to the storage device 2. In step S17, the controller 11 detects that the operation on the A page displayed on the display 1 is a scroll operation from the B page to the C page while dragging the item A8. In step S18, the controller 11 specifies item A8 as the item to be dragged, and specifies page C as the scroll destination page. Then, the controller 11 outputs a control command to the display 1 for changing the display from page B to page C.

In step S19, the controller 11 generates a D page adjacent to the scroll destination B page on the opposite side to the side where the C page is provided. In step S20, the controller 11 changes the affiliation of item A8 to be dragged from page B to page C. In step S21, the controller 11 outputs a control command to delete the A page to the storage device 2.
