Description

  The present invention relates to a content display system that supports selection input of content to be written and displayed on a display holding medium, a management device that configures the system, and a program thereof.

  In general, a printed matter is one in which a fixed image display is performed by supplying a coloring material such as ink or toner from the outside or a developing material onto a medium represented by paper. As a medium that can be substituted for the display and holding medium, an image that can be rewritten according to the writing external force is formed by the writing external force, and the formed image is held in the display state even after the writing external force is removed. The medium is being researched and developed.

  Such a display holding medium contains a display material constituting an image inside a display unit as a region for displaying and holding an image, and writing external force (electricity, magnetism, heat, liquid having a predetermined pH, etc.) is applied to the display material. By applying a chemical action, etc., the display material is physically or chemically changed to form an image corresponding to the writing external force, and even after the writing external force is removed, the display material is formed. The image is maintained, and when a different external writing force is applied, the previous image changes to an image corresponding to the new external writing force. In addition to the fact that the display state is maintained (stored) with no external writing force like that of paper, the display image can be rewritten without supplying a coloring material or developer from the outside. Because it is device-like, it is often called electronic paper.

Here, the application of the mobile phone terminal generates print request data and writes the print request data in the RFID chip of its own terminal, and the user moves the mobile phone terminal closer to the printing device to cause the printing device to read the print request data. A printing system that performs printing is proposed (see Patent Document 1).
Although this patent document 1 is taken up from the viewpoint of “printing from a mobile terminal”, the document does not describe a method for selecting content to be printed.

  According to the program of the eleventh aspect of the present invention, a computer can function as the above management apparatus.

First, a display holding medium (electronic paper) used in the content display system according to the present invention will be described.
Electronic paper is a medium in which an image that can be rewritten according to external writing force is formed by external writing force, and the formed image is held in a display state even after the external writing force is removed. Drive the element by directly applying external force such as electricity, magnetism, heat, etc., drive the element by voltage change accompanying light irradiation, change the coloration state by changing the pH of the liquid accompanying voltage application, etc. There are those using a display principle for driving elements in a chain.
Here, as an example of electronic paper, electronic writing type electronic paper that electronically rewrites an image and optical writing type electronic paper that rewrites an image by light irradiation will be described.

  The electronic writing type electronic paper is a flexible thin medium as large as A4 size paper, for example, and uses fine colored particles (for example, white particles and black particles) used as toner in a copying machine. At least the surface side is sealed between a pair of front and back electrodes, and this is sandwiched between a pair of front and back film substrates whose surface side is transparent at least. An air layer is formed between the electrode layers so that the colored particles can freely move, and an insulating layer for preventing contact with the colored particles is provided on the matrix electrode layer. Note that a color display can be realized with a simple structure by using a color filter.

  In the electronic writing type electronic paper, when no voltage is applied to the electrode, the negatively charged white particles are accumulated on the back surface side, while the positively charged black particles are accumulated on the front surface side. It becomes black when visually observed. Then, when the writing means (driver) of the writing device operates based on the electronic data and reverses the electrode polarity of the required part of the matrix according to the content image to be displayed, the positional relationship between the white particles and the black particles Are replaced, and a content image based on the contrast between the white particles and the black particles is displayed. By operating the driver of the writing device based on different electronic data, the displayed content image can be switched according to the contrast between the white particles and the black particles, and can be reused many times.

  The optical writing type electronic paper is a flexible thin medium having a size like, for example, A4 size paper. For example, a content image is displayed on a writing means (liquid crystal panel) of a writing device. By applying light from the external power supply to the writing electrode while applying the electronic paper to the liquid crystal panel and irradiating light, the content image displayed on the liquid crystal panel can be transferred and displayed and stored. Even after the voltage applied to the electrode is removed, the content image is kept in the display state.

  The optical writing type electronic paper combines, for example, an organic photoconductive material layer (organic photoconductive layer) and a liquid crystal display material layer (microencapsulated cholesteric liquid crystal layer) used in copying machines, These layers are sandwiched between a pair of front and back transparent electrodes, and this laminate is sandwiched between a pair of front and back transparent substrate films. In this configuration, the white display in which the cholesteric liquid crystal layer reflects light and the black display in which the light passes through the liquid crystal layer and is absorbed by the black layer provided between the cholesteric liquid crystal layer and the organic photoconductive layer. Image display is possible. In addition, cholesteric liquid crystals have the property of interfering and reflecting color light according to the helical pitch, so color display can be realized with a simple structure by stacking cholesteric liquid crystal layers with liquid crystals with different helical pitches. Is also possible.

  Optical writing-type electronic paper, for example, displays and projects a content image to be transferred to a liquid crystal panel of a writing device, and when a voltage is applied to the writing electrode, the intensity of light is instantaneously converted into a reflection density. Then, the projected content image is held. The content image displayed and held can be erased by applying an erase voltage to the write electrode.

Next, a writing device for writing content images on the electronic paper as described above will be briefly described.
For example, a writing device of a type applied to electronic writing type electronic paper has a driver (writing means) connected to the electronic paper and, as described above, electronic data (resolution of electronic paper, etc.) The content image based on the display image data conforming to (2) is written on the electronic paper.

In addition, for example, a writing device of a type applied to optical writing type electronic paper is provided on a display surface (writing means) such as a liquid crystal panel for displaying a content image and projecting it on the electronic paper, and the electronic paper. And having the function of applying a voltage to the writing electrode, and writing the content image on the electronic paper placed on the display surface as described above.
Here, the electronic paper and the writing device may be configured as an integrated device, or the electronic paper may be configured as a separate device that is detachable from the writing device.
In the content display system described below, an optical writing type electronic paper and a writing device to which the electronic paper is detachable are used, but other types of electronic paper and writing devices are used. Also good.

In the portable terminal device 2, based on the document list information received from the content server 1 by the first communication unit 21, the document list display processing unit 26 displays the document list screen W 11 as shown in FIG. Let
The document list screen W11 is a screen showing a document list stored in a folder designated by the user, and includes a document name 51 as information for specifying each document and a write ratio value calculated for the document. 52 (percentage in this example) are displayed in a list format in descending order of the write ratio value 52. This figure shows the case where “Matter folder” is designated, and documents such as “machine information”, “pending information”, “customer specific information” are stored in the folder, and the writing ratio is in that order. I can grasp that it is expensive. In this example, list display is performed in units of a predetermined number of documents, and a link 53 to the previous or next list display is also provided on the same screen.

The document name 51 on the document list screen W11 is a link to the single page thumbnail display screen W12 related to the document. When the link is selected by the user, the single page thumbnail display processing unit 27 displays the link in FIG. A single-page thumbnail screen W12 as shown is displayed on the display unit 23.
The single page thumbnail screen W12 is a screen showing a thumbnail image 56 of a page included in the selected document in a single page format, and page position information 57 indicating the position of the page related to the thumbnail display in the document is also displayed. A link 58 to the thumbnail display of the previous or next page is also provided on the same screen.

  The single-page thumbnail screen W12 includes an all-page output instruction receiving unit 54 that receives an output instruction for all pages included in the document related to the thumbnail display, and a single-page output that receives an output instruction for the page related to the thumbnail display. An instruction receiving unit 55 is provided.

The In this example, the list is displayed in units of a predetermined number of pages, and a link 65 to the previous or next list display is also provided on the same screen.

The all-page thumbnail screen W13 includes an all-page output instruction receiving unit 60 that receives an output instruction for all pages included in the document related to the thumbnail display, and one or more selected from the documents related to the thumbnail display. And a selection page output instruction receiving unit 61 that receives an output instruction of the page, and when these are selected by the user, the write request processing unit 29 selects the corresponding page (all pages or selected pages). A page image writing instruction based on the data is transmitted to the writing device 3 by the second communication unit 22, and the page image is written and displayed on the electronic paper 4.
Here, selection of a page to be output by the selected page output instruction receiving unit 61 is received by a page selection unit 63 provided in association with each thumbnail image 62.

In addition, when the thumbnail image is displayed on the single-page thumbnail screen W12 or the all-page thumbnail screen W13, the attribute data update processing unit 16 of the content server 1 stores the corresponding document stored in the content storage unit 11. 1 is added to the display count of the page, and the page of the corresponding document is output in accordance with the output instruction of the page (that is, the page image is written and displayed on the electronic paper 4 by the writing device 3). 1 is added to the write count.
Here, in this example, the mobile terminal device 2 transmits an instruction for adding the number of page display times and the number of writing times to the content server 1, and the attribute data update processing unit 16 determines the number of display times and the number of writing times based on the instructions. Although addition is performed, the present invention is not limited to this. For example, the content server 1 or another device detects a thumbnail display or a writing display on the electronic paper 4, and the display count or writing is performed based on the detection result. The number of times may be added.

In the above description, the case where the document unit is ordered and the document list (document list screen W11) according to the order is displayed has been described. However, the page unit is further ordered and the page list according to the order ( An all-page thumbnail screen W13) may be displayed.
That is, when displaying the all page thumbnail screen W13, the ordering processing unit 14 of the content server 1 calculates the writing ratio for each page for all pages included in the corresponding document, and sets the writing ratio in descending order. Order pages by page order. Then, the list generation processing unit 15 generates page list information according to the ordering by the ordering processing unit 14, and transmits the list information to the requesting mobile terminal device 2 by the communication unit 12. Thus, as shown in FIG. 8, a page list arranged in descending order of the writing ratio is presented to the user, which is different from the original page order. In this case, the writing ratio of each page may be displayed together.

Here, as shown above, all pages included in one selected document are ordered and displayed in a list, and all pages included in multiple documents are ordered (that is, the grouping of documents is ignored). The pages may be ordered and displayed in a list.
Further, when page ordering as described above is not performed, the number of times of display for each document (that is, as a document attribute) is not retained for each page (that is, as a page attribute), and the number of times of display is not retained. Further, the number of times of writing may be held.
Further, in addition to ordering in descending order of the writing ratio (ratio of the number of writings to the number of display times), the ordering may be simply performed in descending order of the writing number.

Next, a case where additional information such as a comment or a tag is added as a page attribute (or document attribute) will be described.
In this case, the ordering processing unit 14 of the content server 1 counts the number of additional information added to each document (or additional information added to each page in the document) for each document to be listed. Then, the documents may be ordered in descending order, or the additional information added to the pages may be counted for each page to be listed, and the pages may be ordered in descending order of the number.

FIG. 9 shows a display example according to the ordering based on the number of additional information.
The document list screen W21 shown in the figure is added by combining a document name 71 as information for specifying each document and the number 72 of additional information added to the document (or each page in the document). The information is displayed in list form in descending order of the number of information 72.

In this example, a comment input screen W23 for adding a comment to each document or page is prepared. The comment input screen W23 is provided on the single page thumbnail display screen W22 for each document on the document list screen W21. Transition is made when the link 73 is selected by the user.
The comment input screen W23 in FIG. 11 includes a comment input field 74, a comment candidate display area 75, an addition target (page or document) selection button 76, a comment input execution button 77, a processing result message display area 78, The comment according to the operation content of the user is added to the page or document as additional information.

Next, a case where a browsing recommendation level is set as a page attribute (or document attribute) will be described.
In this case, the ordering processing unit 14 of the content server 1 sets each document to be listed in the order based on the recommendation level set for the document (or the recommendation level set for each page in the document). Documents may be ordered, or for each page to be listed, each page may be ordered in the order based on the recommendation level set for that page.

  FIG. 10 shows a display example according to the ordering based on the recommendation level. The document list screen W31 in FIG. 10 includes a document name 81 as information for specifying each document, and a recommendation level value 82 of the document. Are displayed in a list form in descending order of the recommendation level 82. In this example, five levels from 1 to 5 are used as the recommendation level, but the recommendation is not limited to this.

Here, the recommendation level may be set manually by a document registrant or administrator, or may be calculated based on each document.
Here, as a method for calculating the recommendation level of the page, for example, the page image is binarized to white or black, and the recommendation level is increased in descending order of the black ratio, or the page image is compressed and compressed. There is a method of increasing the recommendation degree in descending order of the amount of data. Further, the recommendation level of a document can be calculated by the total or average of the recommendation levels of each page in the document.

  In the above description, the contents are ordered using any one of the criteria such as the writing ratio, the number of times of writing, the number of additional information, and the recommendation level, but these criteria are combined to combine the contents. Ordering may be performed.
