Description

  The present invention relates to a display control apparatus capable of displaying display information including a plurality of items and scrolling the display information.

  An information terminal device (information display device) such as a smartphone includes a touch panel type display device, and the display on the display device can be scrolled by a flick operation or a drag operation. One type of information browsed by this type of information terminal device is information transmitted by an information transmitter in a social networking service (SNS) represented by an information transmission site such as Twitter (registered trademark).

  Posts on the SNS are added and increased one after another by posts from other users with respect to posts from a specific user. Therefore, a series of display information including a large number of posts is a large amount including a large number of posts.

  For such display information, a user usually skips many posts in order to find a target post when browsing a post with a predetermined subject or a post from a predetermined contributor. Therefore, a long scroll operation is forced. Further, the user scrolls the display information at a high speed by performing, for example, a high-speed flick operation. For this reason, it is difficult for the user to visually confirm the contents of individual posts while scrolling the display information.

  For such a problem, Patent Document 1 describes that a specific element of displayed information is enlarged according to the scrolling speed. Furthermore, it is described that the scroll speed is adjusted or elements other than the enlarged element are reduced so that the scroll time in the scroll section does not change even if a specific element is enlarged.

  Patent Document 2 narrows down the display target images from a total of 64 images, for example, 8 rows x 8 columns that can be displayed in a list when the scroll speed changes from low to high. It describes that an image to be displayed is enlarged and displayed on one screen.

Embodiment 1
Hereinafter, as a first embodiment of the present invention, a case where the display control device of the present invention is mounted on an information display device having a touch panel will be described with reference to FIGS. However, a touch panel is not essential for the information display device, and the information display device only needs to display display information including a plurality of items on the screen and accept a scroll operation on the display information.

[Configuration of information display device]
FIG. 1 is a block diagram showing a main configuration of the information display device 1. The information display device 1 includes a control unit 10 as a display control device, an input unit 20, a display unit 21, and a storage unit 30. Note that portions that are not directly related to the present embodiment (for example, a portion that communicates with an external device) are omitted from the description of the configuration and the block diagram from the viewpoint of ensuring the simplicity of description. However, the information display device 1 may include the omitted configuration in accordance with the actual situation.

  The information display device 1 is a device that displays predetermined display information. The display information is information in a list form in which a plurality of pieces of information (elements) are collected in a predetermined unit (item) and a plurality of items are connected. In the present embodiment, the display information refers to a set of information posted using the service of the information transmission site, and the information is an article, a comment, an email, or the like that is formed for display by one posting. . Hereinafter, one unit of information such as an article, a comment, and an email is referred to as an item. The item is formed for display by combining several elements. That is, the element is a minimum unit of information constituting the item. Specific examples of display information, items, and elements will be described in detail later with reference to FIGS. 2 and 5. For example, one posted article (item) on the information transmission site includes an account name of the information sender, a posting date, It consists of multiple elements such as the body and attached images.

  Furthermore, the information display device 1 is a device capable of scrolling display information displayed on the display unit 21 in accordance with a user operation. As a result, all items in the display information that cannot be displayed on the screen at a time can be displayed.

  The input unit 20 receives a user operation on the information display device 1, particularly a display information scroll instruction. The display unit 21 includes a flat display panel such as a liquid crystal panel or an organic EL panel, and displays all information processed by the information display device 1 including the display information. The display unit 21 may be configured to serve as the input unit 20 as a touch panel. Alternatively, the input unit 20 may be provided as a button or the like, and the information display device 1 may detect that a specific button has been pressed as a scroll instruction.

  The storage unit 30 is configured by a nonvolatile storage device such as a flash memory, and particularly stores a display setting 31 and a content database (DB) 32. In the content DB 32, every item extracted as display information and all elements included in each item are stored for each item. The content DB 32 may be provided in an external device, and the information display device 1 is configured to download necessary items from the content DB 32 via the Internet when necessary and temporarily store them in the storage unit 30. Also good.

  The control unit 10 controls the information display device 1 in an integrated manner. The control unit 10 is realized by, for example, a CPU (central processing unit). The control unit 10 includes an input detection unit 11, a speed calculation unit 12, a display element determination unit 13, an item region determination unit 14, and a display control unit 15 as functional blocks. These functional blocks process various types of information stored in the storage unit 30, thereby realizing the display control apparatus of the present invention.

[Functional configuration of display control device]
The input detection unit 11 detects a user operation from an input signal received by the input unit 20. Examples of operations detected by the input detection unit 11 include touch, flick, tap, pinch-in, and pinch-out. When the input detection unit 11 detects an operation for instructing scrolling, the input detection unit 11 transmits the input signal to the speed calculation unit 12.

  The speed calculation unit 12 calculates a scroll speed from the input signal. For example, the speed calculation unit 12 obtains the coordinates of the touch start position and the end position and the touch time from the input signal, calculates the flick operation speed, and calculates the scroll speed according to the operation speed. Furthermore, the speed calculation unit 12 may determine a speed classification (a range of the assumed scroll speed is divided into several stages) from the calculated scroll speed (indicated in units of pixel / s, for example). . The scroll speed is transmitted to the display control unit 15, and the speed classification (or may be the scroll speed) is transmitted to the display element determination unit 13.

  The display element determination unit 13 selects (determines) elements to be displayed (hereinafter referred to as display elements) in the items according to the calculated speed category or scroll speed. The display element determined by the display element determination unit 13 is transmitted to the item region determination unit 14 and the display control unit 15, and is processed by the display control unit 15 as an element displayed on the display unit 21. In the present embodiment, the selection of the display element is executed according to the display setting 31 stored in the storage unit 30. The data structure of the display setting 31 will be described in detail later with reference to another drawing.

  The item area determination unit 14 determines the size of the item area for each item. The item area refers to an area occupied by items displayed on the display unit 21 on the screen of the display unit 21.

  Specifically, when the display element is specified by the display element determination unit 13, the item area determination unit 14 reads out the specified display element from the content DB 32 for each item, and stores each display element so that these display elements can be accommodated. Determine the size of the item area of the item. The determined size of the item area is transmitted to the display control unit 15.

  The display control unit 15 forms each item extracted from the content DB 32 for display, and creates display information that can be scroll-displayed by connecting the items. Specifically, for each item, the display control unit 15 reads the display element determined by the display element determination unit 13 from the content DB 32 and reads it into the item area having the size determined by the item area determination unit 14. Arrange each display element. Display information is created by connecting the items formed for display in this way. Further, the display control unit 15 scrolls the created display information according to the scroll speed received from the speed calculation unit 12.

  Thus, when the display information is scrolled according to the input scroll instruction, each item including the display elements selected according to the scroll speed is displayed on the display unit 21.

[About items and elements]
(A)-(d) of Drawing 2 is a figure showing an example of an item. As shown in FIG. 2A, the item 60 is stored in the content DB 32 together with all elements included in the item. As an example, the item 60 is a posted article formed by one posting of one information sender, and is composed of six elements e1 to e6. The header e1 is an element indicating a user name and a user icon indicating a poster and a posting date. Text e2 is an element indicating the body of the posted article. The image e3 is an element of image data attached to the article. The link information e4 is an element indicating link information to external data, and is, for example, a banner advertisement or a URL (Uniform Resource Locator) character string. The number information e5 is an element indicating the number of times the article is viewed and the number of other articles posted in association with the article. The margin e6 is an element that is secured to clarify the separation between adjacent items even when the items are connected. In the present embodiment, it is assumed that the display information is vertically scrolled, and the margin e6 is provided at the bottom or top of the item 60 in order to connect the items vertically. The elements shown in FIG. 2A are merely examples, and the item may include other elements.

  Each element constituting the item is roughly classified into a fixed element and an atypical element. The fixed elements are arranged in a common size at a common position on the item area. On the other hand, the atypical elements may be arranged at different positions, information amounts, or sizes for each item. In the above example, the header e1, the number information e5, and the margin e6 are fixed elements, and the other elements are atypical elements. In the present embodiment, the fixed element may be an element provided in common for all items. On the other hand, the atypical element may not be an essential element.

  As shown in FIGS. 2B to 2D, the display element determination unit 13 selects and selects each of the above elements according to the scroll speed. As the scroll speed increases, the display element of each item is changed. Reduced. The display element determination unit 13 selects a display element according to the following display setting 31 stored in the storage unit 30.

[Display settings]
FIG. 3 is a diagram illustrating a data structure and a specific example of the display setting 31. In FIG. 3, the display setting 31 is shown in a table format data structure as an example, and the data structure of the display setting 31 is not intended to be limited to the table format.

  The display setting 31 is configured to store display rules for each element for each speed category. That is, according to the display setting 31 in FIG. 3, when the speed classification (or scroll speed) is specified, the display rule of each element is uniquely determined.

  The “speed classification” column stores information indicating the speed classification. The definition of the speed category can be designed as appropriate. In the present embodiment, the first speed segment when the scroll speed is 0 or more and less than 500 pixels / second is “stop to ultra-low speed”, and the second speed segment when the scroll speed is 500 or more and less than 1000 pixels / second is “low speed”. The third speed segment when the pixel is 1000 or more and less than 1500 pixels / second is defined as “medium speed”, and the fourth speed segment when the pixel is greater than or equal to 1500 pixels / second is defined as “high speed”. The speed division may be provided with more or less than four stages.

  The “header” column stores a flag indicating whether or not the header e1 is a display element. The “image” column stores the image e3, the “link information” column stores the link information e4, and the “number information” column stores the flag indicating whether or not to use each as a display element. In FIG. 3, a flag “◯” means a rule of selecting a corresponding element at the time of a corresponding speed category as a display element. The flag “x” means a rule that the element at the time of the speed classification is not selected as a display element.

  The “text” column stores information specifying the amount of information when the text e2 is displayed / hidden and displayed. “Full display” means a rule having the entire body of the text e2 as display elements. “Hide” means a rule that the text e2 is not selected as a display element. “Many” means a rule having a part of the body of the text e2 as a display element. “Less” means a rule that uses a part of the body of the text e2 as a display element, which is smaller than the above “more”. Note that the partial use of the text as a display element specifically means that the number of characters or lines is limited to a predetermined number.

  The “margin” column stores information that specifies, in units of pixels, the margin width when the margin e6 is displayed / not displayed and displayed (in the case of vertical scrolling, the margin width). A numerical value larger than 0 stored here means a rule that a margin e6 having a width of the numerical value is adopted as a display element. On the other hand, although not shown, a numerical value of 0 means a rule that the margin e6 is not selected as a display element. As shown in the figure, the margin width of the margin e6 may be increased as the scroll speed is increased. As a result, there is an advantage that it becomes easy to visually recognize a break between items even when the scrolling speed is increased.

  The data format of each display rule is not limited to that shown in FIG.

[Flow of display control processing]
FIG. 4 is a flowchart showing the flow of display control processing executed by the information display device 1. (A)-(d) of FIG. 5 is a figure which shows a specific example of the display information with which the several item was linked.

  It is assumed that the display unit 21 is in a state where display information, for example, a range within a thick frame is displayed in the display information of FIG. In this state, when the input unit 20 accepts an operation related to the scroll instruction (S10), the input detection unit 11 determines that the scroll instruction is input (YES in S12), and the speed calculation unit receives the input signal related to the scroll instruction. 12 to send. The speed calculation unit 12 calculates a scroll speed from the input signal (S14), and further determines a speed category corresponding to the scroll speed (S16).

  In the present embodiment, the display element determination unit 13 may determine whether or not the speed category determined this time has changed from the immediately preceding speed category, and when the speed category has changed (YES in S18). ), Determine that the layout of the item needs to be changed. For example, it is assumed that the scroll speed is increased and the speed classification is changed from “stop to super low speed” to “low speed”.

  And the display element determination part 13 determines a display element according to the display rule (FIG. 3) linked | related with the determined speed classification (S20). Specifically, among the atypical elements, a part of the text e2 (for example, the first three lines) is selected as a display element, and it is determined to reduce the remaining text. Here, all other elements are selected as display elements.

  The item region determination unit 14 extracts the display element selected by the display element determination unit 13 from the content DB 32 for each item, and determines the size of the item region based on the display size of each display element (S22). . For example, the item area of the item 60 is reduced from the size shown in FIG. 2A to the size shown in FIG. 2B by the amount of the first three lines of the text e2 being reduced.

  The display control unit 15 arranges each display element selected in S20 in the item area having the size determined in S22, forms each item for display, and combines these items to display information. Is created (S24). Here, the display information shown in FIG. 5B is created by vertically linking items with reduced elements as shown in FIG. 2B. Finally, the display control unit 15 controls the display unit 21 to display the display information ((b) in FIG. 5), and scrolls the display information at the scroll speed calculated in S14.

  For example, when the scroll operation is continued (YES in S10 and S12), the scroll speed is further increased (S14 and S16), and the speed classification is changed to “medium speed” (YES in S18), the display element is determined. The unit 13 selects a part (for example, the first line) of the text e2 of the atypical element as a display element according to the display rule of FIG. 3 (S20). That is, the amount to be reduced is increased compared to the case of “low speed”. Further, the display element determination unit 13 removes the atypical element that makes the item area non-uniform, that is, the image e3 from the display element. As a result, the display control unit 15 arranges only one line of the text e2 of each item and hides the image e3 ((c) in FIG. 2) (S24). Here, at medium speed, the area of the text e2 is unified into one line, and the image e3 of the atypical element is removed, so that variations in the format of each item are alleviated and individual items can be easily distinguished. There is an advantage that the visibility of the remaining display elements is improved ((c) of FIG. 5). Similarly, when the scroll speed is further increased and the speed classification is changed to “high speed”, the display element determination unit 13 reduces all the non-standard elements and displays only the standard elements according to the display rule of FIG. It selects as an element ((d) of FIG. 2). And the display control part 15 shape | molds an item from the header e1, the number information e5, and the margin e6 ((d) of FIG. 2), As a result, the element displayed in all the items is unified, and each item Variation in the format is eliminated, individual items can be more easily distinguished, and the visibility of the remaining fixed elements is further enhanced ((d) in FIG. 5).

  As described above, the display setting 31 is reduced from the non-standard elements as the scroll speed becomes high, while the standard elements are left as display elements in any speed category, and only the standard elements are displayed at the maximum speed. It is preferable to include display rules that remain. The display element determination unit 13 selects elements according to the above display rules, so that even when the scrolling speed is increased, the visibility when the user finds the target item can be improved, and the scrolling can be performed. It is possible to reduce the amount. In particular, in a configuration in which the number of scroll operations by the user increases according to the amount of scrolling, the effect of this scroll operation can be reduced, so that the effect is particularly great.

  To explain in more detail, when the user performs a scrolling operation on the display information, the user can display the desired purpose on the screen, check whether it is the target item, and send a page. ) Is considered to change the scrolling speed.

  For example, when the user's scroll operation is stopped or at an extremely slow speed, it is considered that the item that the user wants to browse is already displayed on the display unit 21 or is in the immediate vicinity of the display range (thick frame in FIG. 5). . In this case, it is considered that the scrolling distance is not long and there is almost no burden of the scroll operation. Rather, the user may want to browse the contents of the currently displayed item or the most recent item. Therefore, even if the item area becomes large, it is considered appropriate to display all the elements of each item. Therefore, when the speed classification is “stop to super-low speed”, a rule of displaying all display elements is adopted. Thereby, the visibility at the time of finding the target item by the user can be improved without burdening the scroll operation.

  On the other hand, it is considered that as the user's scrolling operation becomes faster, the item that the user wants to display is farther from the display range, and the scrolling distance becomes longer and the burden of the scrolling operation increases. For this reason, the information display device 1 reduces the number of display elements of each item more as the speed classification changes to a section indicating higher speed such as “low speed”, “medium speed”, and “high speed”. , Shrink the item area. Thereby, the distance to scroll can be shortened and the burden of a user's scroll operation can be reduced. In addition, the information display device 1 according to the present embodiment is reduced from the atypical elements (text e2, image e3, etc.) that make the size of the item area or the layout of the items nonuniform among the elements of each item. It is a configuration. Therefore, as the scroll speed increases, the size and layout of the item area of each item are unified. Therefore, the separation position of each item is easy to understand, and the visibility of each item is improved. In addition, if the atypical elements are reduced and the layout is unified, each remaining display element becomes easy to see, and even when scrolling at high speed, the visibility of items and each display element in the item can be improved. . Therefore, it is possible to achieve both improvement in visibility and reduction in the burden of scroll operation.

<< Embodiment 2 >>
The information display apparatus 1 of Embodiment 2 is demonstrated. For convenience of explanation, members having the same functions as those described in the first embodiment are denoted by the same reference numerals and description thereof is omitted. In the information display device 1 according to the second embodiment, the item area determination unit 14 illustrated in FIG. 1 does not determine the size of the item area for each item according to the selected display element, but rather the size of the item area for all items. Make the thickness uniform. More specifically, when the item includes an atypical element as a display element, the display control unit 15 fits in the item area having a uniform size determined in advance by the item area determination unit 14. In addition, the atypical element whose size varies is reduced. Alternatively, the item area determination unit 14 determines the size of the item area for the item (item having the most atypical elements) having the largest item area among all items, and sets the item areas of other items as The structure unified to the said item area | region may be sufficient.

  The display control unit 15 forms each item by arranging the respective display elements in an enlarged or reduced manner so that each selected display element fits in the determined item area size.

  According to the said structure, the magnitude | size of each item is unified in any speed division. Thereby, regardless of the scrolling speed, the division of each item becomes easy to understand, and there is an advantage that the visibility of each element included in each item is improved.
