Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a storage amount display device, and more particularly to a storage amount display device for displaying a storage amount of a user.

[0002]

2. Description of the Related Art In recent years, the operating environment of personal computers, word processors and the like is based on a graphical user interface (G
UI) The environment is mainstream. In particular, the icons that represent the existence of the operation target, as well as the type, function, state, etc. on the screen using pictures and designs so that the user can intuitively grasp them, are important components of the GUI environment Has become.

There are various types of icons. For example,
Well-known are object icons that are opened, moved, or deleted by a user as windows, such as icons represented by pictures of documents, folders, and printers.

[0004] Or, an instruction icon represented by an arrow or an hourglass pattern, a work (tool) icon represented by a pen, an eraser, a spray or the like, and a pattern such as a button, a check box, or a scroll bar. There are control icons and the like represented by.

[0005] In many cases, these icons are modeled on the shape of a well-known object in the real world, so that the function of the operation object can be easily understood, and even if many icons are displayed on the screen. Even if it is placed in the, it is convenient that the target operation target can be relatively easily identified and found.

However, like when many document files are created and stored using the same word processor,
If you create many files using the same application, the icons corresponding to those files will all have the same pattern. In such a case, it is difficult to find a target file from among them.

[0007] In particular, if many files created by the same application are stored in the same folder or drawer, this search becomes more difficult. At this time, the clues of the search are the file names attached to the icons, but reading them one by one to find the target file is a burdensome operation for the user.

[0008] When the user stores new and old (time elapsed since creation) and size (storage usage) of the file to some extent, these can be another clue for searching. Therefore, a device has been proposed in which the visual attributes such as the density, color, and size of the icon are changed and displayed according to the new and old or size of the file, thereby reducing the burden on the user in searching. .

For example, in Japanese Patent Application Laid-Open No. Hei 7-36657, the elapsed time from the creation of a file to the present is measured, and when the elapsed time is short, the color becomes bluish, and as the elapsed time increases, the color changes from yellow to red. When the elapsed time becomes longer, the color of the icon is changed from brown to black, so that the user can intuitively grasp the old and new of the file.

In Japanese Patent Application Laid-Open No. 6-4258, the relative size of a file can be grasped by reflecting the size of the file on the size of the icon.

[0011]

However, in the above-described conventional technology, the file creation time and size are determined by:
Even if the user can easily grasp by changing the visual attribute of the icon and displaying it, the extent to which the user currently remembers the contents of each document file is determined by the icon. You can't tell just by looking at it.

Therefore, even if the user wants to re-learn only one of the many document files whose contents have been forgotten, currently, the user opens the document files one by one and reads the description contents a little. As a result, it is necessary to judge whether or not the document is to be relearned, which is inefficient and troublesome.

Regarding this point, the above-mentioned Japanese Patent Application Laid-Open No. 7-366
As in the invention described in Japanese Patent Application Publication No. 57-57, if the color of the icon is sequentially changed according to the new or old of the document file, the color of the icon is used to determine how much the user stores the contents of the corresponding document file. It can be a very rough guide in doing so.

However, the accuracy of the estimation of the storage amount is not high. This is because forgetting does not proceed in proportion to the length of elapsed time, and the forgetting speed varies greatly depending on the contents of the document.

The present invention has been made in view of the above points, and has as its object to provide a storage amount display device that allows a user to grasp at a glance the storage amount such as how much the user remembers the contents of a document. .

[0016]

According to the present invention, in order to solve the above-mentioned problems, in a storage amount display device for displaying a storage amount of a user, a forgetting speed value generation for generating a forgetting speed value defining a forgetting speed is provided. Means, an elapsed time counting means for counting the elapsed time from the end of the user's reference to the document to the present, the forgetting speed value, the elapsed time, and the user's current storage of the contents of the document. Storage amount estimating means for estimating the storage amount of whether or not, storage amount object generation and display means for generating and displaying a storage amount object visually representing the estimated storage amount, And a data management unit that stores and manages attribute data and data necessary for displaying the storage amount object.

Here, the forgetting speed value generating means generates a forgetting speed value defining the speed of forgetting. The elapsed time counting means counts the elapsed time from when the user has finished referring to the document to the present. The storage amount estimating unit estimates a storage amount indicating how much the content of the document is currently stored by the user from the forgetting speed value and the elapsed time. The storage amount object generation and display means generates and displays a storage amount object that visually represents the estimated storage amount. The data management means stores and manages the document, the attribute data of the document, and data necessary for displaying the storage amount object.

[0018]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a principle diagram of a first embodiment of a storage amount display device according to the present invention. The forgetting speed value generating means 11 generates a forgetting speed value that defines the speed of forgetting. The elapsed time counting means 12 includes a clock and a date and time recording unit, and counts an elapsed time from the end of the user's reference to the document (document file) to the present.

The storage amount estimating means 13 estimates the storage amount of the document file currently stored by the user from the forgetting speed value and the elapsed time. The storage amount object generation and display unit 14 generates and displays a storage amount object that visually represents the estimated storage amount.

The data management means 15 relates to various file data including a document file, related file attribute data (eg, file address, title, application type, capacity, creation date and time), and creation of a storage amount object. Store and manage various data such as data.

Next, the general operation will be described. FIG. 2 is a flowchart showing a schematic operation flow of the first embodiment. [S1] The display unit 16 displays, as windows and icons, a document file created by the user, a document file imported from outside via a communication network or the like. [S2] The data management means 15 stores the document file. [S3] The forgetting speed value generating means 11 generates a forgetting speed value and gives it to the document file stored in the data managing means 15. [S4] The elapsed time counting means 12 determines the date and time when the document files to which the forgetting speed value has been
Alternatively, they are searched and displayed on the display unit 16 as a window.
, The latest display date and time are counted and recorded.

Further, the current date and time are measured, and the elapsed time from the last display of the document file as a window (or from the first save) to the present is calculated. [S5] The storage amount estimating unit 13 uses the forgetting speed value generating unit 1
Forgetting speed value and elapsed time counting means 1 generated by means 1
From the elapsed time obtained in step 2, the current storage amount M (i) of the stored document file is calculated. [S6] The storage amount object generation and display unit 14 calculates the storage amount based on the storage amount estimated by the storage amount estimation unit 13.
Generate and display visually represented storage volume objects. In the first embodiment, based on the difference in the amount of storage,
An icon with a storage amount indicator tag to be attached on the icon image is generated and displayed.

That is, a file name, an icon image, and a tag image to be pasted corresponding to the document file (i) are called from the data management means 15 and combined to generate an icon image with a storage amount indicator. The generated icon with the storage amount indicator is displayed to the user via the display unit 16.

Next, an icon with a storage amount indicator will be described. FIG. 3 is a diagram showing an example of the icon with the storage amount indicator. The icons 14a to 14e with storage amount indicators are composed of icons and tags with indicators. The scale of the indicator indicates the percentage of the storage amount, and the color of the indicator is blue if the storage amount is 50% or more, and red if the storage amount is less than 50%.

For example, the icon 14a with the storage amount indicator has a storage amount of 100% (completely stored).
The color of the indicator is blue. The storage amount indicator icon 14d has a storage amount of 30% (almost forgotten), and the color of the indicator is red.

Looking at such an indicator,
The user can immediately know how much he or she currently stores the contents of the document file. Next, an information table for storing file attribute information will be described.
FIG. 4 is a diagram showing an information table. Information table 15
a is ten attributes of a file name, a file address, an icon image address, a forgetting speed value, a creation date and time, a reference date and time, an elapsed number of days, a storage amount, a type of a pasted tag, and an icon display position (XY coordinates). This is for storing information, and is managed by the data management means 15. In the figure, three files have already been registered.

Next, the forgetting speed setting panel will be described. FIG. 5 is a diagram showing a forgetting speed value setting panel. The forgetting speed value setting panel 16-1 includes a slider 16a that allows the user to set a forgetting speed value, a forgetting curve diagram 16b in which the vertical axis indicates the amount of storage (%) and the horizontal axis indicates days, and several setting switches. , Is composed.

Such a forgetting speed setting panel 16-1
On the other hand, the user can set the forgetting speed value by moving the position of the slider 16a from a keyboard, a mouse, or the like. Next, the forgetting speed value will be described. FIG. 6 is a conversion table for obtaining the forgetting speed value from the set position of the slider 16a. The conversion table 11a includes items of a set position of the slider 16a and a forgetting speed value (α).

The forgetting speed value (α) corresponds to the setting positions 1 to 9 of the slider 16a, and the forgetting speed value (α) increases as the number of setting positions of the slider 16a increases.

For example, if the setting position of the slider 16a is 1, the forgetting speed value (α) is 0.00625, which means that the registered document is hard to forget. If the setting position of the slider 16a is 9, the forgetting speed value (α) is 1.6, which means that it is very easy to forget.

Next, the entry process will be described. Note that the following processing is realized by a microcomputer (hereinafter, a processing unit) not particularly shown in FIG. 1 using a RAM as a work area and executing a control program stored in a ROM or the like. The processing unit operates based on an instruction from a keyboard, a mouse, or the like provided in an information processing system such as a computer.

The entry process is a process for newly registering a document file whose storage amount is to be displayed in the storage amount display device of the present invention. In the first embodiment, the document file immediately after the end of the entry process has a storage capacity of 100
It is displayed as an icon with a storage amount indicator tag indicating%. 7 and 8 are flowcharts showing the procedure of the entry process. [S10] An entry process is instructed from the display unit 16. [S11] A document file is set. [S12] The processing unit creates, in the data management unit 15, an information table 15a for storing the contents of the target file and for storing file attribute information necessary for displaying the icons. [S13] The processing unit sets a file name, a file address, and an icon image address in the information table 15a. [S14] The processing unit calls the forgetting speed value setting panel 16-1 from the data management unit 15, and displays it on the display unit 16. [S15] When the slider 16a is set at an appropriate position on the forgetting speed value setting panel 16-1, the processing section acquires the position information and sends it to the forgetting speed value generating means 11. [S16] The forgetting speed value generation means 11 converts the conversion table 1
1b, the forgetting speed value (α) is obtained from the position information. [S17] The processing unit sets this in the column of the forgetting speed value in the information table 15a. [S18] The clock provided in the elapsed time counting means 12 acquires the current date and time. [S19] The processing unit sets the creation date and time and the reference date and time in the creation date and time and reference date and time fields of the information table 15a set in the data management means 15. That is, in the entry process, the same time data is set in each column of the creation date and the reference date. [S20] The processing unit stores the initial value of the elapsed days (Di = 0) in the elapsed days column of the information table 15a, the initial value of the storage amount (Mi = 1.0) in the storage amount column of the table, and The tag type name (Tag1 = 100%, blue scale) is set in the tag type column of the table. [S21] When the above-described series of processing for setting the file attribute information is completed, the processing unit temporarily stores the information table 15a in the data management unit 15. [S22] The processing unit refers to the address of the file previously stored in the information table 15a, and determines whether it is necessary to display an icon corresponding to the file.
If it is not necessary to display the icon, the process ends here. On the other hand, when it is necessary to display the icon, an icon display process described later is executed.

Next, the icon display processing will be described.
FIG. 9 is a flowchart showing the flow of processing when displaying an icon with a storage amount indicator tag. [S30] The processing unit receives an instruction to display an icon. [S31] The processing unit reads the attribute information stored in the information table 15a of the data management unit 15, refers to the address of the icon image and the type of tag, and generates a tag image for displaying each icon image and storage amount. From the data management means 15 and send them to the storage object generation / display means 14. [S32] The storage amount object generation / display unit 14 first obtains an icon composite image with a storage amount indicator tag by transferring and attaching a tag image to a specified position on the icon image. [S33] The storage amount object generation and display means 14 acquires the file name from the information table 15a, and
The icon composite image obtained in step 32 is transcribed to a predetermined lower area, and then combined to obtain an icon composite image with a file name. [S34] The storage amount object generation and display unit 14 determines the display position of the synthesized icon image, and
6 and the processing unit stores the position information (XY coordinates) in the display position column of the information table 15a. [S35] The display unit 16 receives the combined image of the icon with the storage amount indicator tag and the file name from the storage amount object generation display unit 14, and displays it at the position determined in step S34. [S36] It is determined whether there is an icon to be displayed,
If more icons need to be displayed, the process returns to step S31. If it is not necessary, the process ends.

Next, the tag image determination table will be described. FIG. 10 shows a tag image determination table. The tag image determination table 140 includes items of a storage amount M and a tag type.

Regarding the rule for determining a tag image, for example, if the storage amount M is 0.85> M ≧ 0.75,
Tag 3, with 80% storage and blue indicator. The determined tag type is described in the information table 1
In the type field of the pasted tag 5a, it is set so as to be replaced with the old tag type name.

Next, a process of updating the storage amount of the storage file will be described. The icon immediately after the entry process is completed has an indicator tag indicating the storage amount of 100%. However, this scale decreases exponentially with the passage of time unless the content of the file corresponding to the icon is referred to. I will do it.

When the storage amount given to the file falls below a certain value (M = 0.45 in FIG. 10), the color of the scale also changes from blue to red, thereby causing the user's attention to be forgotten. It is designed to make it easier to find files with sexual characteristics. Such a change in the scale is determined by the data management means 1.
5 is provided by the update processing of the storage amount performed for all the files stored in the storage unit 5.

The updating process can be executed periodically according to a predetermined schedule, or can be executed each time an icon display request is issued. In the first embodiment, the updating process is performed. Update processing is performed each time is started. FIG. 11 is a flowchart showing a flow of an update process at the time of starting the storage amount of the storage file. [S40] The processing unit detects an activation signal. [S41] The processing unit reads the contents of the information table 15a of the file (i) (first line) stored in the data management unit 15. [S42] The clock provided in the elapsed time counting means 12 acquires the current date and time Tp. [S43] The elapsed time counting means 12 calculates the difference (elapsed time) between the reference date and time from the current date and time (D (i) = Tp-Tr).
(I)) After it is converted into a day value, the result is sent to the storage amount estimating means 13 and set in the elapsed days field of the information table 15a. [S44] The old elapsed day value is deleted, and the storage amount estimating means 13 substitutes the acquired elapsed days D (i) and the read forgetting speed value α (i) into the following equation to store the current stored days. Quantity M
Find (i).

[0039]

M (i) = exp (−α (i) · D (i)) (1) For example, “idea memo 1” stored in the first row of the information table 15a shown in FIG. Is stored as exp (-
0.1 × 7.7) = 0.463. The processing unit receives the calculation result from the storage amount estimating unit 13, sets the storage amount column of the information table 15 a by replacing the old storage amount, and sends the same to the storage amount object generation display unit 14. [S45] In the storage amount object generation and display means 14,
The type of tag is determined by comparing the acquired storage amount with the tag image determination table 140 shown in FIG.

For example, the storage amount M of the above “idea memo 1” is 0.463, which is 0.55> M ≧ 0.4
Since it corresponds to 5, the tag type is Tag 6 (50% blue)
Is determined. The determined tag type is set in the type column of the pasted tag in the information table 15a so as to be replaced with the old tag type name. [S46] The information table 15a of the file (i) updated to the new contents by the above series of processing is stored in the data management means 15. [S47] The processing unit obtains the address of the file (i) from the information table 15a and determines whether or not to display an icon. Here, if it is determined that the icon needs to be displayed, the icon display processing described above is executed. On the other hand, if it is not necessary, the process proceeds to step S48 without performing the display process. [S48] The processing unit determines whether or not there is a file to be updated by referring to the information table 15a. If so, the processing unit stores the next file (for example, stored in the second line) in the information table 15a. Update processing of attribute information. The process returns to step S41 and repeats until there are no more files to be updated, and then the process ends.

Next, the updating process after referring to the file will be described. Suppose that the user finds an icon with a small storage amount, opens it as a window, checks the contents, and closes it. Immediately after this, the storage amount of the document is initialized to 1.0.
And the icon changes to the one with the 100% storage amount indicator tag attached. FIG. 12 is a flowchart showing the flow of the update process after the file is referenced. [S50] The processing unit detects a window display end signal for the file (i) from a mouse or the like. [S51] The window displayed on the display unit 16 is closed. [S52] The elapsed time counting means 12 obtains the date and time when the window was closed using the inherent clock, and sends it to the processing section, which sends it to the information table 15a of the file (i). Write in the field. At this time, the reference time already stored therein is deleted. [S53] The processing unit further sets the initial value of the elapsed days (Di =
0) in the age table of the information table, the initial value of the storage amount (Mi = 1.0) in the storage amount column of the table, and the tag type name (Tag 1 = 100%, blue scale). Set each in the tag type column of the table. [S54] After setting, the file attributes are stored in the information table 15a.
Is stored. [S55] The processing unit refers to the address of the file (i) stored in the information table 15a,
It is determined whether the icon corresponding to the file needs to be displayed. As a result, if it is not necessary, the processing is terminated here. On the other hand, if display is necessary, the icon display process described above is executed and the process ends.

As described above, in the first embodiment, the storage amount is estimated in accordance with the exponential function characteristic using the forgetting speed value and the elapsed time as parameters, and the storage amount indicator image is added to the icon image. It was configured to be attached and displayed. This allows the user to immediately know how much the contents of the document file are stored.

Next, the first embodiment of the present invention will be described in more detail. Memory for empirical events generally decays exponentially with time, as is well known as the forgetting curve. That is, a certain event (i)
The storage amount M (i) can be expressed as Expression (1) described above.

Therefore, a constant α (i) which is specific to the event (i) and defines the forgetting speed, and the event (i)
, The storage amount M (i) of a certain event (i) at a certain elapsed time can be obtained.

The estimation of the storage amount of the document file in the first embodiment is based on this knowledge. First, the forgetting speed value generating means 11 generates a constant α (i) that defines the forgetting speed according to the contents of the document file (i) to be stored.

Regarding the size of the constant α (i) to be generated for a certain document file, the user who reads the document expects the content to be easy to forget (or easy to remember). And the constant α
There is a method of generating and calculating (i) and a method of automatically assigning an appropriate constant α (i) according to a difference in the type of document file without requiring the user to make such a prediction. The method is not particularly limited.

The document file is stored in the data management means 15 after the forgetting speed value is generated. The elapsed time counting means 12 calculates D in the equation (1), and the elapsed time from the time when the document file is stored in the data management means 15 to the present, or the time from the most recent display of the document file to the present. Time the elapsed time.

The storage amount estimating means 13 is activated when the system is activated or when requested by the user. The memory amount estimating means 13 obtains the constant α (i) indicating the forgetting speed value generated by the forgetting speed value generating means 11 and the elapsed time counting means 12. The elapsed time D is expressed by the following equation (1).
Is calculated for the document file stored in the data management unit 15 as an estimated value of the current storage amount.

As described above, the document files stored in the data management means 15 are given an appropriate storage amount. Storage amount object generation and display means 14
Displays the storage amount given to the document file by the storage amount estimation means 13 on the icon image. For example, the storage amount is pasted as it is on an icon image as it is, or converted into a graphic expression such as a scale, and then pasted on the icon image. Further, it is also possible to express the storage amount by changing visual attributes such as the color, movement, size, transparency, and inclination of the icon according to the difference in the storage amount.

According to such a configuration, the estimation of the storage amount for the stored document file is based on the fact that the storage decays exponentially with respect to the elapsed time, and that the decay tendency depends on the difference in the file contents. Since it is performed in accordance with the forgetting characteristic of human memory, which differs depending on the user, it is possible to relatively accurately estimate how well the user stores the contents of a certain document file.

Further, since the estimated storage amount can be represented on the icon image corresponding to the document file, the user can immediately see how much he or she remembers the contents of the document file by just looking at the icon. It becomes possible to grasp.

Next, a second embodiment of the present invention will be described. In the second embodiment, the forgetting speed value, the elapsed time,
The storage amount is estimated in accordance with the exponential function characteristics using three of the cumulative reference times as parameters. In the first embodiment, the storage amount is updated for all the stored files at the time of startup. However, in the second embodiment, a file that needs to be displayed every time an icon display request is issued is performed. The update processing of the storage amount is performed only for.

FIG. 13 is a principle diagram of the second embodiment of the present invention. The same components as those in FIG. 1 are denoted by the same reference numerals and description thereof will be omitted. The reference count recording means 17
Count and record the cumulative reference count of the document. The storage amount estimating means 13-1 estimates the storage amount from the forgetting speed value, the elapsed time, and the cumulative reference count. The storage amount object generation and display unit 14-1 performs various image conversion processes for changing the color, size, shape, and the like of the icon in order to generate the storage amount object. Here, an example in which the amount of rotation conversion is changed according to the calculated storage amount will be described.

Next, the icons that rotate according to the storage amount will be described. FIG. 14 is a diagram showing icons that rotate according to the amount of storage. Figure icon images 14f-14j
In the graph, the degree of inclination increases as the storage amount decreases.

For example, the icon 14f has a storage amount M = 1.
0, in which case there is no rotation. Icon 14j
Is the storage amount M = 0.0, and in this case, it is rotated by 90 °.

By observing the degree of the inclination of the icon, the user can immediately know how much he or she currently stores the contents of the document file. Next, an information table for storing file attribute information will be described. FIG. 15 is a diagram showing an information table. The information table 15b includes a file name, an address at which file contents are stored (file address), an address at which an icon image is stored (icon address), a forgetting speed value, a creation date and time, a reference date and time, a reference count, and an icon. For storing the eight attribute values of the display position (XY coordinates) of the image data. In addition,
In the figure, attribute values for three files are already stored.

Next, the entry process will be described. FIG.
6, FIG. 17 is a flowchart showing the processing procedure of the entry processing. [S60] The display unit 16 instructs entry processing. [S61] A document file is set. [S62] The processing unit creates an information table 15b in the data management unit 15 for storing the contents of the target file and storing file attribute information necessary for displaying the icon. [S63] The processing unit stores the file name, the file address, and the icon image address in the information table 1 respectively.
Set to 5b. [S64] The processing unit calls the forgetting speed value setting panel 16-1 from the data management unit 15 and displays it on the display unit 16. [S65] The processing unit obtains position information from the position of the slider 16a set by the user, and sends it to the forgetting speed value generation unit 11. [S66] The forgetting speed value generation means 11 converts the conversion table 1
The forgetting speed value (α) is obtained from the position information with reference to 1a. [S67] The processing section sets this in the column of the forgetting speed value in the information table 15b. [S68] The clock provided in the elapsed time counting means 12 acquires the current date and time. [S69] The processing unit sets the creation date and time and the reference date and time in the creation date and time and reference date and time columns of the information table 15b set in the data management means 15. That is, in the entry process, the same time data is set in each column of the creation date and the reference date. [S70] The reference recording unit 17 sets the number of times of reference Ni = 0. [S71] When the above-described series of processing for setting the file attribute information is completed, the processing unit stores the information table 15b in the data management unit 15.

Next, the icon display processing will be described.
Unlike the first embodiment, first, a storage amount calculation process is performed, and based on the obtained storage amount, an icon image is subjected to rotation conversion and displayed. FIG. 18 is a flowchart showing a processing procedure when displaying an icon image which is tilted as the storage amount is reduced. [S80] The processing unit receives an instruction to display an icon. [S81] The content (attribute information) of the information table 15b relating to the first file (i) to be displayed is read from the data management means 15. [S82] The elapsed time counting means 12 acquires the current date and time using the attached clock and sends it to the processing section. [S83] The processing unit subtracts the read reference date and time from the acquired current date and time, and converts the result into a day value to calculate an elapsed date and time. [S84] The storage amount estimating unit 13-1 determines the forgetting speed value α (i) and the number of times of reference N from the read information table 15b.
(I) Further, the elapsed date and time D obtained in step S83
(I) is received, and each is substituted into the following equation to calculate the current storage amount M (i).

[0059]

M (i) = exp (− (α (i) −N (i) · Δα (i)) · D (i)) (2) where Δα (i) is the file (i) 1)
It represents an increment due to a learning effect caused by referring to the time (window display). In the second embodiment, the increment is calculated as a constant (0.01 · α (i)) for convenience. In Equation (2), the minimum value of α (i) −N (i) · Δα (i) is defined as 0.001.

For example, if the storage date of the file "Principle of BS method" shown in the information table 15b is 7.06 days, the forgetting speed value .alpha.
Since (i) = 0.025 and the number of references N (i) = 3, exp (− (0.025−3 × 0.01 × 0.02)
5) × 7.06) = 0.8426. [S85] The processing unit receives this result and sends it to the storage amount object generation / display unit 14-1. First, the storage amount object generation / display unit 14-1 obtains the rotation angle θ (i) at the time of icon display by substituting the value into the following equation.

[0061]

（(I) = 90 × (1−M (i)) (3) For example, the conversion angle of the icon corresponding to the file “principle of the BS method” shown in the information table 15b is the storage amount Is 0.8
426, so 90 × (1-0.8426) = 14.1
Calculated as 7 [S86] The processing unit acquires the icon image from the data management unit 15 by referring to the address of the icon image from the read information table 15b, and sends it to the storage amount object generation display unit 14-1 together with the calculated rotation angle. . [S87] In the storage amount object generation / display means 14-1, each pixel constituting the icon image is rotationally moved (transcribed) in a counterclockwise direction according to the following equation to obtain an inclined icon image.

[0062]

X = x · cos θ (i) + y · sin θ (i) (4a) Y = −x · sin θ (i) + y · cos θ (i) (4b) where X and Y are icons These are coordinates obtained as a result of rotating a pixel (x, y) constituting the image by θ (i). [S88] The storage amount object generation / display unit 14-1 calculates a position where the icon image is to be displayed. [S89] The storage amount object generation / display unit 14-1 passes the icon image after the rotation conversion to the display unit 16, and the display unit 16 displays the icon image. [S90] The processing unit determines whether there is a file for which an icon display instruction has been received, and if so, repeats a series of processes from step S81 to step S89 for the file. When there are no more icons to be displayed as icons, the process ends.

Next, the updating process after the file is referred will be described. FIG. 19 is a flowchart illustrating the update processing procedure after the file is referenced. It is assumed that the user finds an icon (that is, a file having a small storage amount) that is greatly inclined to the left, opens the content as a window, checks the content, and then closes the window. Immediately thereafter, the storage amount of the file is updated to 1.0, and the icon is displayed in an upright state. FIG. 19 shows the flow of this updating process. [S100] The processing unit detects a window display end signal. [S101] The processing unit closes the window of the corresponding file. [S102] The elapsed time counting means 12 obtains the current time using the attached clock and sends it to the processing unit. [S103] The processing unit sets this in the reference date and time column of the information table 15b. At this time, the data of the old reference date and time that has already been stored is deleted. [S104] Upon receiving the window end signal, the reference count recording unit 17 refers to the numerical value (count) stored in the reference count column of the information table 15b, and sets the value obtained by adding 1 to the new count as the reference count. Return to column. [S105] The processing unit stores the information table 15b. [S106] If the icon needs to be displayed subsequently, the above-described icon display processing is performed; otherwise, the process ends.

As described above, in the second embodiment, in addition to the constant α (i) indicating the forgetting speed value and the elapsed time D, the document file (i) provided by the reference count recording means 17 The storage amount is estimated in consideration of the cumulative reference number N (i).

That is, when estimating the storage amount, by subtracting the value corresponding to the accumulated reference count from the constant α (i) indicating the forgetting speed value generated first, the forgetting speed increases as the document is more frequently referenced. I tried to be late.

This method of estimating the amount of memory is based on the empirical fact that the memory related to the same event is strengthened as the amount and the number of learning experiences increase (that is, the learning / practice effect or the repetition effect). Therefore, it is possible to more accurately estimate the storage amount than in the first embodiment.

Next, a third embodiment will be described.
The third embodiment is characterized in that a memory check on the contents of a stored document file is performed for a user, and the forgetting speed value that defines the magnitude of the forgetting amount is changed as needed based on the result. is there.

Therefore, an appropriate forgetting speed value can be asymptotically obtained without the user having to predict and set the forgetting speed value at the time of entry. FIG. 20 is a principle diagram of the third embodiment. The same components as those in FIG. 1 are denoted by the same reference numerals, and description thereof is omitted. The storage checking unit 18 checks the degree of storage related to the contents of the document. The forgetting speed value changing unit 19 changes the forgetting speed value obtained by the forgetting speed value generating unit 11 based on the inspection result of the storage inspection unit 18.

Next, the storage inspection means 18 will be described.
FIG. 21 is a diagram illustrating a configuration example 1 of the storage inspection unit 18.
The storage inspection unit 18a of the configuration example 1 is the question sentence generation unit 1
8a-1, an answer obtaining means 18a-2, and an answer result determining means 18a-3.

The question sentence generating means 18a-1 generates an examination screen including a question sentence for a memory check. The generated question text is displayed on the display unit 16 to the user. The answer obtaining means 18a-2 obtains the user's answer to the question.
The answer result determination unit 18a-3 compares the obtained answer with the answer stored in the data management unit 15 at the time of entry, and determines whether the answer is correct or incorrect. And
The result is transmitted to the forgetting speed value changing means 19.

FIG. 22 is a diagram showing a configuration example 2 of the storage inspection means 18. The storage inspection unit 18b of the configuration example 2 includes a question sentence generation unit 18b-1 and a subjective rating value acquisition unit 18b.
-2.

The question sentence generating means 18b-1 generates an inspection screen including a question sentence for a memory check. The generated question text is displayed on the display unit 16 to the user. The subjective rating value obtaining means 18b-2 responds to the displayed question by
It is determined whether or not the user can answer, and a subjective evaluation value regarding the memory of the user is obtained therefrom. Then, the result is transmitted to the forgetting speed value changing means 19.

Next, a description will be given of a pop-up window which is an inspection screen displayed when the memory inspection unit 18 performs the memory inspection. FIG. 23 is a diagram showing an example of a pop-up window in the storage inspection unit 18a.

In the pop-up window 16-2,
A question sentence "What is the meaning of the language of cherry blossoms?" Is specified, and the user can select and input an answer to the question. In addition, a user interface is provided that immediately provides feedback as to whether the answer is correct or incorrect.

Although a method of selecting a correct answer is adopted here, a method of determining whether the answer is correct by typing in the answer and matching the correct answer is also possible.

FIG. 24 is a view showing an example of a pop-up window in the storage inspection means 18b. In the pop-up window 16-3, a question sentence "Please answer three or more technologies for realizing eye-gaze matching in the teleconference system" is specified, and the user himself / herself "remembers" according to whether this question can be answered. A user interface is provided for judging whether the user has entered or forgotten and selecting and inputting.

In either of the configurations shown in FIGS. 23 and 24,
The question must be created by the user himself. In the configuration of FIG. 23, an objective memory test is possible, but the user himself has to create a plausible option (in the case of an option question) related to the contents of the correct answer and the question text.

Next, a step table used to change the forgetting speed value based on the result of the memory inspection will be described. FIG. 25 is a diagram showing an example of the step table. For example, if the evaluation result is "remembered" after the user's memory test, the forgetting speed value is changed to the forgetting speed value β smaller by one step than the current state. "I forgot"
Then, the forgetting speed value β that is one step larger than the current state
Change to

Next, the entry process will be described. The icon display process and the update process after referring to the file
The description is omitted because it is the same as in the first embodiment. FIG.
6, FIG. 27 is a flowchart showing the procedure of the entry process. [S110] The entry process is instructed from the display unit 16. [S111] A document file is set. [S112] The processing unit sends the data management
An information table for storing the contents of the target file and storing file attribute information necessary for displaying the icon is created. [S113] The information table includes a file name, a file address, an icon image address, a question text address, a forgetting speed value, a creation date and time, a reference date and time, an elapsed number of days, a storage amount, a type of a pasting tag, and an icon display position ( XY coordinates)
Are stored. Then, the processing unit sets a file name, a file address, and an icon image address in the information table. [S114] The processing unit calls up the inspection screen from the data management unit 15 and displays it on the display unit 16. This inspection screen includes a message prompting the user to create a question sentence,
An area for inputting a question sentence and a completion button.

The user uses a keyboard or the like to input a question sentence related to the contents of the file to be entered into this input area. Note that the format of the question sentence is arbitrary, and may be, for example, "What is"? "Or" Please explain about ". [S115] When the completion is instructed by the user's operation, the processing unit sends the created question message to the data management unit 15
To be stored. [S116] The address of the question text is registered in the information table. [S117] The processing unit sets a default value (βinitial = 0.1 in the third embodiment) defined in advance in the information table as an initial value of the forgetting speed value. [S118] The clock provided in the elapsed time counting means 12 acquires the current date and time. [S119] The processing unit sets the creation date and time and the reference date and time in the creation date and time and reference date and time columns of the information table set in the data management means 15. That is, in the entry process, the same time data is set in each column of the creation date and the reference date. [S120] The processing unit sets the initial value of the elapsed days (Di = 0).
In the age table of the information table 15a, the initial value of the storage amount (Mi = 1.0) in the storage amount column of the table, and the tag type name (Tag1 = 100%, blue scale). Are set in the respective tag type fields. [S121] After the above-described series of processing for setting the file attribute information is completed, the processing unit temporarily stores the information table in the data management unit 15. [S122] The processing unit refers to the address of the file previously stored in the information table, and determines whether it is necessary to display an icon corresponding to the file. If it is not necessary to display the icon, the process ends here. On the other hand, if the icon needs to be displayed, the above-described icon display processing is executed.

Next, a process of updating the storage amount of the storage file and the forgetting speed value will be described. In the third embodiment, as in the first embodiment, the storage amount is updated for all the stored files every time the apparatus is started.
As a result of the updating process, for a file having a storage amount of 0.5 or less, a question message regarding the content of the file is displayed, and the forgetting speed value is determined according to whether or not the user has answered the question. Make changes to the values. FIG. 28 and FIG. 29 are flowcharts showing the flow of the update process at the time of startup. [S130] The processing unit detects an activation signal. [S131] The processing unit reads the contents of the information table of the file (i). [S132] The elapsed time counting means 12 acquires the current date and time. [S133] The elapsed time counting means 12 calculates the number of elapsed days. [S134] The storage amount M (i) is obtained by substituting the elapsed days and the forgetting speed value set in the information table into the following equation.

[0082]

M (i) = exp (−β (i) · D (i)) (5) where D (i) is the number of days elapsed since the document file i was registered or referred to. , Β (i) are forgetting speed values. Therefore, although the calculation method itself is the same as that of the first embodiment, β (i) is different from α (i) and is changed at any time based on the processing result of the storage inspection unit 18 described below. It is a fluctuation value. [S135] The type of tag is determined and set. [S136] When the storage amount is calculated in step S134, the processing unit compares the storage amount with a predetermined threshold value (M (θ) = 0.5 in the third embodiment). If the storage amount is equal to or larger than the set threshold value 0.5, the process proceeds to step S
If not, go to step S137. [S137] The processing unit reads the question message from the data management unit 15 with reference to the address of the question message stored in the information table. [S138] An appropriate display position of the question text is determined. [S139] The display unit 16 combines the image for window display with the question text, and displays a pop-up window for a memory test. [S140] The user's subjective evaluation value is obtained from the memory test pop-up window. [S141] Based on the difference between the answers obtained by the subjective evaluation value obtaining means 18b-2, the forgetting speed value changing means 19 changes the forgetting speed value set in the information table. The step table 19a is used for this change. If it is forgotten, the process proceeds to step S142. If it is forgotten, the process proceeds to step S147. [S142] The forgetting speed value changing means 19 changes the forgetting speed value to a specified value smaller by one step than the current value. However, in the case of the third embodiment, the minimum value of the forgetting speed value is set to 0.00625, and this value is continuously used even if the rating is “remembered” even after reaching the minimum value ( By the way, this minimum value is equivalent to reaching the storage amount 0.5 after about 55 days.) [S143] "Confirmation of contents" is displayed in the memory inspection window.
Even if a button is prepared and the user evaluates “remember”, the user can confirm the contents of the document file by pressing this button. If confirmation, proceed to step S148; otherwise, proceed to step S1.
Go to 44. [S144] The information table with the updated attribute information is stored in the data management unit 15. [S145] If an icon needs to be displayed, an icon with a storage amount indicator is displayed according to the same processing flow as in the first embodiment. If the display of the icon is unnecessary, the process proceeds to step S146. [S146] The processing unit checks whether or not there is still a storage file to be updated. If so, the process returns to step S131 to repeat a series of update processes, and if not, ends the process. [S147] The forgetting speed value changing means 19 changes the forgetting speed value by one step from the current state with reference to the step table 19a. However, the maximum value of the forgetting speed value is defined as 1.6, and even after that, "forgot"
This value is used even if the evaluation is obtained (by the way, this value is converted to reach the storage amount 0.5 after about 0.4 days). [S148] If the rating is "forgotten," the contents of the document file are automatically displayed as a window.
That is, the processing unit obtains the contents of the document file from the data management unit with reference to the address of the file stored in the information table. [S149] The processing unit determines the display position of the window. [S150] The processing unit passes the file contents and the display position information to the display unit 16, and the display unit 16 displays the contents of the document in a window. When the window display processing is completed, step S
Go to 146. When the contents of the file are confirmed by the user and the window is closed, the above-described update processing after the reference is performed, and the processing ends. As described above, in the third embodiment, the configuration is such that the storage amount is estimated based on the result of the storage check on the contents of the document file in addition to the forgetting speed value β (i) and the elapsed time D. did.

That is, the storage amount inspection means 18 performs an inspection for evaluating the degree of storage related to the contents of the document file for the user. Based on the inspection result, the forgetting speed value changing unit 19 changes the value of the constant β (i) that defines the forgetting speed generated by the forgetting speed generating unit 11.

As a result, it is possible to make an adjustment so that the forgetting speed becomes slow for a document file which can be answered in the past, and the forgetting speed becomes fast for a document file which cannot be answered. By repeating this, it is possible to gradually approach the storage amount very close to the actual storage level of the user.

In the third embodiment, the forgetting speed value β is set so as to be increased or decreased by one step in accordance with the result of the alternative evaluation of whether it is forgotten or forgotten. If the inspection means 18 is set to allow a multi-level rating (for example, a five-level evaluation with “completely forgotten” to “completely remembered” as both poles), β is increased or decreased by two or more steps at a time. As a result, an appropriate forgetting speed value can be obtained faster.

Next, a fourth embodiment will be described.
FIG. 30 is a principle diagram of the fourth embodiment. The same components as those in FIG. 1 are denoted by the same reference numerals, and description thereof will be omitted.
The display determination means 20 sets a display threshold M (θ) in which the storage amount M (i) estimated by the storage amount estimation means 13 is set.
, All document files having a storage amount smaller than the threshold value are detected.

If the icons corresponding to those files are not on the desktop, the storage amount object generation / display unit 14 is instructed to generate a shortcut icon (a copy of the icon) with the storage amount indicator tag. I do.

The display threshold value setting means 21 sets and changes the display threshold value M (θ). This is realized by displaying a threshold setting panel on the display unit 16 and providing a user interface that allows a user to input a threshold using an input device such as a mouse or a keyboard.

By adding these two components, in the fourth embodiment, the document files stored in the data management means 15 have a storage amount of, for example, 0.3 or less, that is, It can detect only those that are at high risk and display shortcut icons corresponding to those files on the desktop. Further, the corresponding document may be displayed on the desktop.

Thus, for example, a document file stored in the lower part of the directory hierarchy is also displayed with good timing when the user is about to forget, so that forgetting of the document content can be avoided and effective learning can be performed. It becomes possible.

The flow of the entry process and the display process of the icon with the storage amount indicator tag in the fourth embodiment are the same as those described in the first embodiment, and therefore are omitted, and the update process at the time of startup is omitted. Subsequent display processing of the shortcut icon on the desktop, update processing after reference, and subsequent deletion processing of the shortcut icon from the desktop will be described.

In the following description, the display threshold M (
θ) = 0.3, and this value is the display threshold value setting means 2
It is assumed that the setting is made in the display judging means 20 through the line 1. The form of the shortcut icon is a tag image (for example, “C”) that clearly indicates that the icon is a copy of the icon.
Mark) is pasted on the icon image.

FIG. 31 is a flowchart showing the flow of the updating process at the time of startup. Note that the flow of processing from step S160 to step S165 is exactly the same as the update processing of the first embodiment described with reference to FIG. [S160] The processing unit detects an activation signal. [S161] The processing section reads the contents of the information table of the file stored in the data management means 15. [S162] The elapsed time counting means 12 acquires the current date and time. [S163] The elapsed time counting means 12 calculates the number of elapsed days and sets it in the information table. [S164] The storage amount estimating means 13 estimates the storage amount and sets it in the information table. [S165] The storage amount object generation and display unit 14
Determine the type of tag. [S166] The processing unit refers to the address of the file in the information table, checks the location of the file, and determines whether the icon is located on the desktop.
When the icon is placed on the desktop, the above-described icon display processing is performed, and the icon with the storage amount indicator tag is displayed on the desktop. Upon completion of the icon display processing, the flow advances to step S168.

On the other hand, if the icon has not been placed on the desktop, the process proceeds to step S167. [S167] The processing unit calculates the storage amount M (i) acquired in step S164 and the display threshold value M (θ) set in the display determination means 20 via the display threshold value setting means 21 =
Compare with 0.3. As a result, if M (i) <0.3, a process of displaying a shortcut icon with a storage amount indicator tag described below on the desktop is performed. M
(I) If ≧ 0.3, go to step S168. [S168] The processing section stores the information table in the data management means 1.
Set to 5. [S169] It is determined whether there is a file to be updated by referring to the information table. If there is a file to be updated, the process returns to step S161; otherwise, the process ends.

Next, the display processing of the shortcut icon will be described. FIG. 32 is a flowchart showing the flow of the shortcut icon display process. [S170] Display of a shortcut icon is instructed. [S171] The processing unit sets a shortcut icon creation log in the information table 15a. [S172] The processing unit acquires a tag image (for example, a “C” mark) that clearly indicates that the icon is a shortcut icon from the data management unit 15. [S173] The storage object generation / display unit 14 reads the icon image. [S174] The storage amount object generation / display unit 14 reads the storage amount display tag image. [S175] The storage amount object generation / display unit 14 transcribes and affixes two tag images, a tag image specifying the shortcut icon and a storage amount display tag image, to a specified position on the icon image, respectively. A shortcut icon image with a storage amount indicator tag is generated. [S176] The storage object generation / display unit 14 obtains the file name from the information table, transcribes the file name into a predetermined lower area of the icon composite image, and combines the icons to generate an icon composite image with a file name. . [S177] The processing section determines the display position and sets the display position in the information table. It should be noted that the display location of the shortcut icon is defined in advance so as to be in the desktop area which is the first hierarchy of the directory. [S178] The storage amount object generation / display unit 14 displays a storage amount display tag and a shortcut icon with a file.

Next, the process of deleting the shortcut icon after referring to the document file will be described. FIG. 33 is a flowchart showing the flow of the initialization processing of the storage amount and the deletion processing of the shortcut icon performed after referring to the document file.

It is assumed that, after a shortcut icon with a storage amount indicator corresponding to a document file having a storage amount of less than 0.3 is displayed on the desktop, the user opens the window, checks the contents, and then closes the window. As described in the first embodiment, in such a case, an update process for initializing the storage amount M (i) to 1.0 is executed. In the fourth embodiment, an update process is additionally performed. The process of deleting the shortcut icon displayed on the desktop is also executed. [S180] The processing unit detects a window display end signal. [S181] The window displayed on the display unit 16 is closed. [S182] The elapsed time counting means 12 acquires the current date and time and the reference date and time. [S183] The processing unit sets the number of days elapsed, the amount of storage, and the tag type name in the information table. [S184] The processing unit determines whether or not there is a shortcut icon corresponding to the referenced document file on the desktop by examining the information table for a log for creating a shortcut icon. If it is confirmed that the shortcut icon is on the desktop, the process proceeds to step S185. Otherwise, step S188
Go to [S185] The storage amount object generation / display unit 14 deletes the shortcut icon from the desktop. [S186] The processing section also deletes the log for creating the shortcut icon in the information table. [S187] The processing unit stores the information table in the data management unit 1.
After setting to 5, the process is terminated. [S188] After closing the window, it is determined whether or not an icon needs to be displayed by referring to the address of the file in the information table. If display is necessary, the above-described icon display process is performed. If there is no need to display, the process proceeds to step S187.

As described above, according to the fourth embodiment, based on the size of the storage amount estimated by the storage amount estimating means 13, a stored document file having no icon placed on the desktop is determined. In addition, it is configured to determine whether to display the shortcut icon on the desktop or to display the contents of the document as a pop-up window. As a result, for example, a document file stored in the lower part of the directory hierarchy can be displayed in a timely manner when the user is about to forget it, thereby avoiding forgetting the document content and performing effective learning. It becomes possible.

[0099]

As described above, the storage display device of the present invention is configured to estimate the user's storage amount from the forgetting speed value and the elapsed time and display this storage amount as a storage amount object. This allows the user to immediately grasp how much the document is stored.
