Abstract

PROBLEM TO BE SOLVED: To provide a list display device and a program thereof capable of allowing a user to search for and find a desired data from a list in a short time with an intuitive operation.SOLUTION: A list display device 1 includes: an input part 2 for inputting at least two points; a control section 4 that increases/reduces the number of items of a list including plural items according to the input width between the input two points and updates the display of the items according to a predetermined reference; and a display section 3 that displays the list.

Description

  The present invention relates to a list display device that allows a user to search and find desired data from a list in a short time by an intuitive operation and a program thereof.

  When a user tries to find out desired data from the list, the data is usually searched in the following procedure.

  First, several items that meet a certain condition are selected from a plurality of items (first step). Next, desired data is selected by comparing this in detail (second step).

  However, in the first step, when checking the list in order from the top, it is necessary to remember the position of the data of interest. When new interesting data is found and the user wants to compare the contents with the previously found data, the user needs to scroll to find the position of the data in the list.

  Further, in the second step, it is not possible to compare the data of interest side by side. Therefore, it is necessary for the user to make detailed comparisons by printing the data of interest individually.

  As a conventional technique for solving these problems, as a contribution to the improvement of the first step, a favorite function, a rearrangement function, or a narrowing function for registering favorites is selected as a contribution to the improvement of the second step. There is a detailed comparison function that displays the details of the items side by side.

  However, these functions vary depending on the list display device and the provider of the list display program, and there is no standard user interface. In addition, many screen transitions and many check boxes are used, making intuitive operation difficult. In particular, when this operation is performed on a terminal such as a smartphone or a car navigation device, it is difficult to say that the operability is excellent due to restrictions on the input device and the screen size.

  Japanese Patent Application Laid-Open No. H10-228561 describes a technique for increasing search efficiency by changing the scroll speed of the list. Japanese Patent Application Laid-Open No. 2004-228688 describes a technique for improving search efficiency by displaying two sublists in a system that selects one item from a list of a plurality of items.

  However, these are located on an extension of the conventional list search procedure described above. That is, it provides a tool or technique for efficiently performing a conventional list search procedure.

  Therefore, an object of the present invention is to provide a list display device and a program for the same, which allow a user to search and find desired data from a list in a short time by an intuitive operation.

  Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1)

  FIG. 1 is a block diagram illustrating a configuration of a list display device according to the present embodiment.

  In FIG. 1, the list display device 1 includes an input unit 2, a display unit 3, a control unit 4, a list storage unit 5, and a density data storage unit 6.

  The input unit 2 receives input from the user to the list display device 1 and notifies the control unit 4 of the input information. The input unit 2 only needs to be capable of inputting at least two positions. Examples of the input unit 2 include a pointing device such as the touch panel 21 and the mouse 22, a keyboard 23, and the like. When these devices are externally attached, various interfaces provided in the list display device 1 correspond to the input unit. In the present embodiment, an example in which the touch panel 21 is used for the input unit 2 will be described.

  The touch panel 21 receives an input accompanied by a touch and movement from a user. The touch panel 21 is configured to be able to detect two or more touch positions. When the user is performing a pinch operation, in addition to the touch position of the user, information such as the movement direction of the touch position, the distance between the touch positions, and the coordinates of the touch position is notified to the control unit 4.

  The input width based on the position of two points that are input information input from the input unit 2 will be described with reference to FIG. In this example, the touch panel 21 is used for the input unit 2.

  A distance between two touch positions 211 input to the touch panel 21, that is, a two-point distance 213 before the start of displacement is a typical example of the input width. The coordinates of the two touch positions 211 also correspond to the input width. The user's finger moves to the pinch-in position 212 by moving the touch position on the touch panel 21, that is, by performing a pinch-in operation. The distance between the pinch-in positions 212, that is, the point-to-point distance 214 after the start of displacement (including the end of displacement) also corresponds to the input width. Further, a point-to-point distance (Y) 215 and a point-to-point distance (X) 216 are obtained by projecting the point-to-point distance 213 before the start of displacement in the vertical axis (Y-axis) direction and the horizontal axis direction (X-axis direction). It corresponds to the input width here. The displacement amount 217 and the displacement direction 218 from the touch position 211 to the pinch-in position 212 also correspond to the input width here. Although not shown in the figure, the distance between two points 214, the displacement amount 217, and the displacement direction 218 after the start of displacement are projected in the vertical axis and horizontal axis directions, which corresponds to the input width here.

  Note that FIG. 2 shows the pinch-in operation as an example, but the same applies to the pinch-out operation.

  The display unit 3 is composed of a liquid crystal display or the like, and displays a list to be described later. In this embodiment, the touch panel 21 is overlaid and integrated. Therefore, the list displayed on the display unit 3 can be operated as if it were directly handled by a finger.

  The control unit 4 reads the list from the list storage unit 5 and displays it on the display unit 3, accepts input from the touch panel 21, interprets the input, increases or decreases the number of items in the list 51 as will be described later, and The display of 53 is updated.

  The list storage unit 5 stores and holds the list 51. The list storage unit 5 transfers the list 51 to the control unit 4 and the display unit 3 according to an instruction from the control unit 4.

  The density data storage unit 6 stores and holds display candidates for items 53 described later. The density data storage unit 6 also transfers the item 53 to the control unit 4 according to an instruction from the control unit 4. The contents of the density data stored in the density data storage unit 6 will be described later with reference to FIG.

FIG. 3A is a schematic diagram of a list 51 held in the list storage unit 5.
The list 51 includes data 52 and items 53.

  The data 52 is information having an objective value for the content itself. For example, in the case of an e-mail, the e-mail body, in the case of merchandise information, the type of merchandise, in the case of tourist information, the name of a tourist spot, and the like.

  The item 53 means a constituent element of the list attached to the data 52 included in the list 51, and includes a description of the name, symbol, number, classification, set, attribute, property, index, and the like of the data 52. For example, in the case of e-mail, information such as the date and sender of the e-mail body and the sender, etc., in the case of product information, the price of goods, the date of arrival, the supplier, etc. An example is a regular holiday at a tourist spot. In addition, for example, in the case of a major league team, information indicating the hierarchy of the major league team's affiliation region, affiliation league, or the like can also be an item.

  In addition, when the item 53 is a date, the minute, hour, day, month, year, and the width thereof, in the case of a monetary amount, the unit of the monetary amount or the width of the monetary amount, in the case of letters, the alphabetical order or alphabetical order, Various other units can also be the item 53.

  A list 51 is typically a combination of at least the data 52 and the item 53. Note that the list 51 before the start of the operation of the present invention does not necessarily include the item 53.

  FIG. 3B is an example of the list 51. FIG. 3B is a popularity ranking list of sightseeing spots in Okinawa. In this case, specific tourist spot names are data 52 and ranks are items 53.

  Next, the operation of the list display device 1 in this embodiment will be described with reference to FIGS. 4, 5, and 6. 4, 5, and 6 are explanatory diagrams illustrating the operation of the list display device 1.

  First, as shown in FIG. 4A, the second place OKINAWA fruit and the fifth place Mihama American Village are touched with two fingers. Then, when a pinch-in operation is performed to bring two fingers close to each other in the vertical direction, the table data from the second place to the fifth place are collected according to the width of the finger and changed to a list as shown in FIG. In other words, the 2nd and 3rd positions are combined and updated to the item 53 “ranking 2nd to 3rd place”, and the 4th and 5th positions are combined and the item “ranking 4th to 5th” is displayed. 53 is updated and displayed. Then, the number of items in the list 51 decreases from 4 to 2. As a result, the length (height) of the updated item 53 portion of the list 51 is shortened, and other items 53 can be displayed.

  In this case, the density of the data 52 corresponding to the item 53 is as follows. Since the data 52 corresponding to the “second place” item 53 before the pinch-in operation is only “OKINAWA fruit”, the density of the data 52 is 1. However, since the data 52 corresponding to the item 53 “ranking 2nd to 3rd” during the pinch-in operation is “OKINAWA fruit” and “Ryukyu Mura”, the density of the data 52 is 2. That is, the density of the data 52 for the item 53 is large.

  If the pinch-in operation is further continued, the list changes to that shown in FIG. That is, the item 53 “ranking 2nd to 3rd” and “ranking 4th to 5th” is updated to the item 53 “ranking 2nd to 5th” and displayed. Then, the number of items in the list 51 decreases from 2 to 1.

  In this case, the data 52 corresponding to the item 53 of “ranking 2nd to 5th” is “OKINAWA fruit”, “Ryukyu Mura”, “Koza gate street”, and “Mihama American Village”. The density of is 4. That is, the density of the data 52 for the item 53 is further increased.

  In this way, the items 53 displayed following the pinch-in operation are grouped according to the distance 214 between the two points after the start of the displacement as the input width. For example, when the point-to-point distance 214 after the start of displacement changes to one-half of the point-to-point distance 213 before the start of displacement, the items 53 sandwiched between the two points are grouped so that the number of items is halved. At the same time, the display of the item 53 is updated to correspond to it. The data density corresponding to the item 53 is doubled.

  If the input width during the pinch-in operation is smaller than a predetermined width, the item 53 may not be displayed.

  For example, as shown in FIG. 5, when the input width becomes smaller than the height (display width) of one item 53, the item 53 is not displayed. However, in order to clearly indicate that the grouped item 53 exists between the other items, for example, as shown in FIG. 5, there are doubled lines separating the items 53 and the grouped item 53 exists between them. This may be shown to the user.

  In the case of this embodiment, the tourist spot name as the data 52 is not displayed in FIGS. 4B and 4C due to the size of the display unit 3, but may be displayed in some form.

  On the other hand, when a pinch-out operation in which two fingers are moved away from each other in the vertical direction is performed on the grouped items 53, the grouped state is canceled according to the distance 214 between the two points after the start of displacement as the input width.

  First, as shown in FIG. 6A, when a pinch-out operation is performed by touching the portion of the item 53 “ranking 2nd to 5th” with two fingers as shown in FIG. The item 53 “ranking 2nd to 5th” is updated to the item 53 “ranking 2nd to 3rd” and “ranking 4th to 5th”. When the pinch-out operation is further performed, as shown in FIG. 6C, the summarized item 53 “ranking 2nd to 3rd” is changed to “item 2” and item 3 “ranking”, and “ The item 53 of “4th to 5th ranking” is updated to the item 53 of “4th” and “5th”. In this process, the number of items increases from 1 to 2, 2 to 4, and the density of the data 52 corresponding to the item 53 changes from 4 to 2, from 2 to 1.

  Instead of the pinch-out operation, the collected items 53 may be released in stages by double-tapping.

  Next, the operation of the list display device 1 in the present embodiment will be described with reference to a flowchart. FIG. 7 is a flowchart for explaining the operation of the list display device 1. Such an operation can be realized by executing software on the list display device 1.

  First, the control unit 4 reads the list 51 to be displayed from the list storage unit 5 and displays it on the display unit 3 (S11).

  Next, the touch panel 21 detects a user's two touch positions (S12). Thereby, the distance 213 between the two points before the start of the displacement as the input width is detected. Subsequently, the touch panel 21 detects a pinch action, and detects information on the input width between two points specified by the action of the user's finger, here, the distance 214 between the two points after the start of displacement or the displacement amount 217 ( S13). These input widths detected by the touch panel 21 are notified to the control unit 4.

  The control unit 4 specifies the data 52 at the position sandwiched between the two points from the distance 213 between the two points before starting the displacement. Then, the number of data 52 is specified (S14).

  The control unit 4 calculates the number of data 52 that can be newly displayed based on the distance 213 between two points before the start of displacement and the distance 214 between the two points after the start of displacement or the displacement amount 217 (S15). For example, when the displacement amount 217 has such a length that the four data 52 can be narrowed to an area where the two data 52 can be displayed, the control unit 4 sets the number of displayable data 52 to two. This is the number of items that can be displayed.

  The control unit 4 updates the item 53 based on the number of displayable items 53 (S16). For example, in the case of the popularity ranking list of tourist spots described in the present embodiment, since the item 53 is numerical data, the numbers of the ranks to be combined into one item are proportionally distributed so as to fit within the number of items 53 that can be displayed. And the item 53 is updated.

  When the item 53 is not numeric data, information necessary for updating is read from the density data storage unit 6 and used.

  Then, the updated list 51 is displayed based on the number of displayable items 53 and the corresponding updated items 53 (S17).

  By repeating the above operation and following the user's pinch operation to update the list 51 as needed, the operation of the list display device 1 reflecting an intuitive operation can be realized.

  In this embodiment, the detection of the pinch operation is detected by the operation in the vertical direction. In the case of a table arranged vertically as in the present embodiment, the operation direction matches the direction of display change, which contributes to a more intuitive operation. In the case of a device that operates while holding the touch panel 21 in the horizontal direction, for example, a tablet-type terminal or a smartphone, it is desirable to detect motion in the vertical direction.

  However, in the case of a device that is operated by holding the touch panel 21 in the vertical direction, such as a car navigation device or a television, the vertical pinch operation places a burden on the body and is always easy to operate due to the structure of hands and fingers. It can not be said. Therefore, a pinch operation for moving a finger in an oblique direction may be assigned. The input width may be a distance between two points (Y) 215 based on the vertical axis. Furthermore, the distance projected on the vertical axis may be detected as the distance 214 between the two points and the displacement 217 after the start of the displacement. In other words, an intuitive operation can be realized by extracting and processing the vertical component of the oblique operation.

  As described above, the detection of the touch and the detection of the pinch operation may be determined based on ergonomic considerations according to the usage state of the device used.

As described above, the user can collect or hide data unnecessary for the user. This function is more effective when it is not known whether desired data is included in the list. For example, when searching for data that matches a condition from the list 51, it is possible to display only data that finally meets the condition by collecting or not displaying data that does not match the condition.
This eliminates the need for the user to memorize where in the list the data that matches the condition was found, or to scroll through the list looking for that data.

(Embodiment 2)

In the first embodiment, for the portion sandwiched between the two input positions, the number of items is increased and decreased, and the item 53 is updated and displayed. In the present embodiment, an example in which the number of items is increased or decreased with respect to the entire list 51 and the item 53 is updated will be described.
In the second embodiment, the configuration of the list display device 1 is the same as that of the first embodiment as shown in FIG.

  FIG. 8 is an explanatory diagram showing the operation of the list display device 1.

  First, as shown in FIG. 8A, the four corners of the list 51 are touched with two fingers. Then, when a pinch-in operation is performed to bring two fingers closer to each other in an oblique direction, all the lists 51 displayed according to the width of the fingers are collected and changed to a list 51 as shown in FIG. In other words, the 1st to the 12th are put together, “ranking 1st to 2nd”, and similarly, “ranking 3rd to 4th”, “ranking 5th to 6th”, “ranking 7th to 8th” ”,“ Ranking 9th to 10th ”, and“ ranking 11th to 12th ”items 53 are updated and displayed.

  When the pinch-in operation is continued, the list 51 is changed as shown in FIG. That is, the items 53 are updated and displayed as “ranking 1st to 4th”, “ranking 5th to 8th”, and “ranking 9th to 12th”.

  In this case, the number of items changes from 12 to 6, from 6 to 4, and the density of the data 52 changes from 1 to 2, 2 to 4.

  The difference from the first embodiment is that not only the data 52 sandwiched between the two touched points but also the items 53 of the data 52 in other areas are updated. For example, in FIG. 8B, the item 53 is updated to the item 53 having the density 2 also in the ranking 13th and lower.

  Next, the operation of the list display device 1 in the present embodiment will be described with reference to a flowchart. FIG. 9 is a flowchart for explaining the operation of the list display device 1. Such an operation can be realized by executing software on the list display device 1.

  First, the control unit 4 reads the list 51 to be displayed from the list storage unit 5 and displays it on the display unit 3 (S21).

  Next, the touch panel 21 detects two touch positions 211 of the user (S22). Thereby, the coordinates 211 of the two touch positions as the input width are detected. Subsequently, the touch panel 21 detects a pinch-in operation, and detects an input width input by the user, here, the distance 214 between the two points after the start of displacement, the displacement 217, and the displacement direction 218 (S23). These input widths detected by the touch panel 21 are notified to the control unit 4.

  The control unit 4 determines from the coordinates 211 of the two touch positions and / or the displacement direction 218 that the entire list 51 is targeted (S24).

  The control unit 4 adjusts the number of items that can be newly displayed based on the coordinates 211 of the two touch positions and the distance 214 between the two points after the start of displacement or the displacement amount 217 (S25), and updates the item 53. (S26). These operations are the same as S15 and S16 of the first embodiment.

  Based on the updated item 53, the updated list 51 is displayed (S27).

  By repeating the above operation and following the user's pinch operation to update the list 51 as needed, the operation of the list display device 1 reflecting an intuitive operation can be realized.

In this embodiment, in order to distinguish from the operation of the first embodiment, the detection of the pinch operation is detected by the operation in the oblique direction.
However, as an example for use in a car navigation device, a television, or the like, it has been described that an oblique operation may be assigned in the first embodiment. In this case, in order to distinguish from the operation of the first embodiment, the detection of the pinch operation may be detected by a horizontal operation. In this case, the input width may be a distance between two points (X) 216 with respect to the horizontal axis. Furthermore, the distance 217 and the distance 214 between the two points after the start of the displacement may be detected as the distance projected on the horizontal axis.

  In the present embodiment, the item 53 is updated for all the displayed data 52 on condition that the touch positions are four corners and the displacement direction 218 of the pinch operation is diagonal. However, although the density of the data 52 is changed, other conditions may be used.

  For example, only the touch positions at the four corners may be used as a trigger. Moreover, it is good also considering only the operation | movement of the diagonal direction as a trigger. In this case, the operation of the second embodiment is performed regardless of the touch position. Since the first embodiment detects the displacement direction 218 in the vertical direction, the first embodiment and the second embodiment can be distinguished from each other by detecting the displacement direction 218.

  In addition, Embodiment 1 and Embodiment 2 are functions that are independent from each other, and any one of them corresponds to the present invention.

  As described above, the user can freely change the density of data in the entire list. This function is more effective when recognizing that the desired data is included in the list. For example, when searching for data that matches a specific condition, first increase the data density for the item with a pinch-in operation, and then decrease the data density with a pinch-out operation from a specific item. You can get there.

For example, when searching for a mail with a specific date and time from a list of a large amount of mails sorted in date order, it has been necessary to scroll the list to a specific date and time.
If this embodiment is used, the target data can be easily reached by first creating a list compiled in units of months by pinch-in, and then pinching out the items of the month including a specific date and time.

(Other embodiments)

  In the following, other embodiments will be described sequentially from the viewpoints of input devices and operations, lists, devices, and software. In addition, it is possible to use in arbitrary combinations including these examples described in Embodiments 1 and 2.

(1) Input device and operation

  In Embodiment 1, 2, although the touch panel 21 was used for the input part 2, another device can also be used. Here, an example using a mouse 22 as a pointing device will be described.

  First, as shown in FIG. 10A, the second-place OKINAWA fruit is selected by placing the cursor on the second-place OKINAWA fruit and clicking.

  Next, while maintaining the click action, drag the range from the 2nd place OKINAWA fruit to the 5th place Mihama American Village and drop it at the 5th place Mihama American Village. Thereby, p, which is the distance 213 between the two points before the start of displacement, which is the input width, is input, and the data 52 sandwiched between the two points is selected. That is, the data 52 is a processing target.

  Then, as shown in FIG. 10B, by clicking the head position where the updated item is to be displayed, q, which is the distance 214 between the two points after the start of displacement, which is the input width, is input. Then, the number of items corresponding to the ratio of p and q is set, and the display of the item 53 is updated as shown in FIG. This process is the same as in the first embodiment.

  On the other hand, when the cursor is moved to the grouped item 53 and double-clicked, the grouped state is released in stages.

  Of course, other operations of the mouse 22 may be used in combination. Alternatively, even when the touch panel 21 is used, an operation other than the pinch operation may be assigned.

(2) List

  In the first and second embodiments, the popularity ranking list of sightseeing spots in Okinawa is used as an example of the list 51, but examples of other lists will be described.

FIG. 11 is an explanatory diagram showing the operation of the list display device 1 when a received mail list is used.
In this case, the data 52 is the title of the mail, and the item 53 is the date and time when the mail is received (FIG. 11A). Then, according to the pinch-in operation, the item 53 is updated from the specific date and time when the mail is received to the item 53 having a time width (every 2 hours in this example) (FIG. 11B). If the pinch-in operation is further continued, the item 53 becomes the afternoon in the morning (FIG. 11 (c)), and thereafter updated to the day and month. These item 53 candidates are read from the density data storage unit 6 and used.

  FIG. 12 is a diagram showing details of the density data storage unit 6. In the density data storage unit 6, candidates for the item 53 are classified and stored. For example, in the case of a calendar item, seconds, minutes, hours, days, and years are stored as items 53 in descending or ascending order. Each item 53 stores the amount or number up to the next upper item 53. For example, the number 24 is assigned to the hour item 53, which means that the day of the upper item 53 is reached in 24 hours. By using this data, intermediate items can be generated. For example, depending on the number of items to be displayed, when the hour item is updated to the day item, the display area may remain. In that case, 24 is proportionally distributed, and the item 53 is generated and updated every two hours as in the example of FIG. 11B.

FIG. 13 is an explanatory diagram showing an operation of the list display device 1 when a search result list of books in a shopping mall on the Internet is used.
In this case, the data 52 is the title of the book, and the item 53 is the price of each book (FIG. 13A). Then, according to the pinch-in operation, the item 53 is updated from the individual specific price of the book to the item 53 consisting of the price range (in this example, every 100 yen) (FIG. 13B). If the pinch-in operation is further continued, the item 53 is updated so as to increase the price range (in this example, 500 yen) (FIG. 13C).

  In the case of numerical data such as a price, the item 53 to be updated is read out from the price range stored in the density data storage unit 6 and used, or in accordance with the number of items to be updated. You may obtain | require by calculating.

In the embodiments described so far, the case where the item 53 is already included in the list 51 before the operation is shown, but it can be used even when the item 53 is not included in the list 51 before the operation.
For example, in the case of a list consisting of a name list arranged in the order of 50 tones, items representing 50 tones according to the pinch-in operation, for example, “A”, “A, I, U”, “A”, “A”, “K” ”, Etc.” may be newly created and displayed.

Note that the example of the list so far has been the case where the item 53 has one dimension, that is, one dimension, but it can also be used in the case of two or more dimensions.
For example, as shown in FIG. 14, if separate items 53 are set for the X-axis and the Y-axis, and the vertical and horizontal pinch operations are detected, it can also be used to select more diverse information. is there.

(3) Equipment and software

  The list display device 1 of the present invention is sufficient if it can display a list. Examples include desktop and notebook computers, tablet information terminals, smartphones, mobile phones, and car navigation devices.

  The functions of the present invention may be realized by dedicated hardware, but may be realized by mounting software (program) having the functions of the present invention on general-purpose hardware.

  That is, as shown in FIG. 15A, in order to utilize the resources of the hardware 100, application software may be mounted on the hardware. In this case, the application 103 receives information from the user input from the hardware 101 via the hardware 101.

  Alternatively, as illustrated in FIG. 15B, the application 103 may receive information from the user input from the hardware 101 via the OS or the middleware 102. Specifically, a subroutine or library prepared by the OS or middleware 102 is used. In other words, the difference is whether the application itself has an information conversion function for using the hardware level input at the application level or the OS or the like.

  Further, it goes without saying that the application 103 in FIG. 15A and FIG. 15B corresponds to the program of the present invention, but software including both the application 103 in FIG. 15B and the OS or middleware 102 may also be used. This corresponds to the program of the present invention.

  The list display device of the present invention can be used for display devices in general and can be used in any field.
