When a user selects to add of an item of the data area 30 to the graphic area 40 using drag-and-drop on a UI screen, the first controller 150 controls the display 120 to display a graph generated on the basis of the conditional data about whether graphicalization is possibly stored in the fist storage unit 130 in the graphic area 40. Here, a graph type (a bar graph, a pie chart, etc.) may be set up by a user in advance and stored in the first storage unit 130. However, it is also understood that the user selects an item and moves the selected item to a predetermined area to display in a visual form (for example, a bar bowl graph, a pie chart, etc.)
The conditional data about whether grouping and linking are possible may be stored in Table 2 shown below.







TABLE 2




















According to an embodiment with reference to Table 2, the row may represent an existing data item, and the column may represent a data item newly added. The first storage unit 130 stores conditions about grouping or liking possibility of a plurality of graphs regarding the data of the image forming apparatus by items in a matrix format as Table 2.
Here, the number “1” represents a case where grouping is possible, and the number “2” represents a case where linking is possible in Table 2.
For example, in the case data can be grouped into an item such as location and a model name, the first controller 150 integrates a plurality of graphs into one graph and displays it in the graphic area 40.
Further, in the case data can be linked as an item such as a model name and a status, the first controller 150 divides the graphic area 40 and displays a plurality of graphs in divided areas, respectively, and a graph in each area is linkable according to a user's selection.
The first storage unit 130 may be realized by internal or external storage modules such as an HDD, a flash memory, etc. However, it is not limited thereto. User information stored in the first storage unit 130 of the host apparatus 100 according to the embodiment may include store authorization information for confirmation in an administrator mode or by the user.
Meanwhile, the first storage unit 130 further stores program information to execute the web solution currently installed in the host apparatus 100.
When the web solution is executed, the controller 150 controls the first communication unit 140 to receive a data of an image forming apparatus from an external device (the server 200) or at least one image forming apparatus 300-1, 300-2, . . . , and 300-n and stores a received data in the first storage unit 130.
Further, when a function of generating a graph about a data of an image forming apparatus is selected in the web solution, the first controller 150 controls the display 120 to load a stored data and to display a UI screen including the data area 30 and the graphic area 40.
Here, the first communication unit 140 receives a data directly from at least one connectable image forming apparatus 300-1, 300-2, . . . , and 300-n or a data of an image forming apparatus from the server 200 which stores a data of each (or some) image forming apparatus.
The reception of a data may be conducted by user's selection of executing the web solution or periodically (or non periodically) by a predetermined reserved time.
The first communication unit 140 communicates with at least one image forming apparatus 300-1, 300-2, . . . , and 300-n, the server 200, etc., and may be realized by a cable or wireless communication module connected locally or via a network according to a protocol with an external device, e.g., the image forming apparatus 300-1, 300-2, . . . , and/or 300-n or the server 200.
The first controller 150 controls the host apparatus 100 overall. The first controller 150 may be realized in a combination of software such as a web solution firmware, etc. and hardware such as a central processing unit (CPU).
Specifically, the first controller 150 connects to at least one of image forming apparatus 300-1, 300-2, . . . , and 300-n or the server 200 via the first communication unit 140 responding to execution of the web solution, and receives and stores a data of the image forming apparatus 300-1, 300-2, . . . , and 300-n in the first storage unit 130.
Here, the stored data of the image forming apparatus may include data of each (or some) image forming apparatus by items, conditional data about whether graphicalization by items is possible as in Table 1, and conditional data about whether grouping and linking are possible as in Table 2.
Moreover, as necessary, the conditional data about whether graphicalization by items is possible as in Table 1 and the conditional data about whether grouping and linking are possible as in Table 2 may be stored in advance in the first storage unit 130.
Further, in the case of the server 200, which is provided independently, when receiving user's selection of graphicalizing a certain item, the first controller 150 controls the first communication unit 140 to load conditional data about whether graphicalization by items is possible and conditional data about whether grouping and linking are possible stored in the server 200 and the display 120 to display the loaded conditional via graphicalization.
When a function of generating a graph of a data of an image forming apparatus is selected via the user input unit 110 while the web solution is executed, the first controller 150 controls the display 120 to display a UI screen including the data area 30 and the graphic area 40 as shown in FIG. 3.
As shown in FIG. 3, the data area 30 displays a data of an image forming apparatus as at least one column corresponding to at least one item. Here, the data area 30 may display a data of an image forming apparatus in each item in a grid format.
A user may select any one item in the data area 30 of FIG. 3 to be graphicalized and added to the graphic area 40.
Here, the user selects a column 31 corresponding to an item to be added and transfers it to the graphic area 40 by drag-and-drop.
Meanwhile, the host apparatus 100 of an embodiment may be realized as follows: a user selects any one item, i.e., the column 31, and selects an add button, which is separately provided on the UI screen of FIG. 3, thereby displaying a data of the selected column as a graph in the graphic area 40.
In FIG. 3, when any one item is selected to be graphicalized, the first controller 150 may control the display 120 to generate a data of an item 31 selected as in FIG. 4 into a graph according to the conditional data on whether graphicalization is possibly stored in the first storage unit 130 (refer to Table 1) and to display it in the graphic area 40. That is, numerical data is converted into a graphical visual form.
Here, if the selected item 31 is set up to be graphicalizable in the conditional data of Table 1, the first controller 150 controls the display 120 to generate and display a graph as shown in FIG. 4.
For example, if a user selects the item 31 of a model name, information about usage of each model is displayed in the graphic area 40.
Furthermore, if the selected item 31 is set up to be not graphicalizable in the conditional data of Table 1, the first controller 150 controls the display 120 to generate and display a message 50 that graphicalization is impossible as shown in FIG. 5. When the user selects an OK button 51 corresponding to the message 50 of FIG. 5, the first controller 150 controls the display 120 so that the UI screen goes back to the previous screen as in FIG. 3.
Meanwhile, in the case the conditional data on whether graphicalization is possible as in Table 1 is stored in the server 200, which is provided separately, when a user selects any one item 31 to be graphicalized in FIG. 3, the first controller 150 controls the first communication unit 140 to load the conditional data on whether graphicalization is possible from the server 200 and the display 120 to display a UI in FIG. 4 or 5 on the basis of the loaded conditional data.
Meanwhile, the user may select any one item in the data area 30 to be graphicalized and added to the graphic area 40 in the state where a data of an image forming apparatus regarding any one item is graphicalized and present in the graphic area 40, as shown in FIG. 6.
Here, the user selects a column 32 corresponding to an item to be added and transfers it to the graphic area 40 by drag-and-drop.
The first controller 150 determines whether a data of an existing graph and a data of a newly added item can be grouped according to the conditional data about whether grouping and linking are possibly (refer to Table 2) stored in the first storage unit 130, and controls the display 120 to generate and display an integrated graph in the graphic area 40, as shown in FIG. 7.
For example, if a location item 32 is selected to be graphicalized in the presence of a graph about usage information by dates in the graphic region 40, as shown in FIG. 6, the first controller 150 makes certain that the date and location items can be grouped, i.e., are set up to “1,” in the conditional data of Table 2 and controls the display 120 to generate and display an integrated graph showing usage information by dates and locations, as shown in FIG. 7.
Moreover, the user may select any one item in the data area 30 to be graphicalized and added to the graphic area 40 even in the state where a data of an image forming apparatus regarding any one item is graphicalized and present in the graphic area 40, as shown in FIG. 8.
The first controller 150 determines whether a data of an existing graph and a data of a newly added item can be grouped according to the conditional data about whether grouping and linking are possible (refer to Table 2) stored in the first storage unit 130, divides the graphic area 40 into a first area 43 and a second area 45, and controls the display 120 to generate and display the existing graph (a first graph) and a graph of the newly added data (a second graph) in the first area 43 and the second area 45, respectively, as shown in FIG. 9.
For example, if the location item 32 is selected to be graphicalized in the presence of a graph about a status of an image forming apparatus in the graphic region 40, as shown in FIG. 8, the first controller 150 makes certain that the status and location items can be grouped, i.e., are set up to “2,” in the conditional data of Table 2 and controls the display 120 to display two graphs showing status information and status information by locations in the divided graphic areas 43 and 45, respectively, as shown in FIG. 9.
Here, if the user selects any one state, e.g., a warning 44, from the first graph of the first area 43, as shown in FIG. 9, the first controller 150 may display the second graph indicating location information about the selected state in the second area 45.
Likewise, if the user selects any one state, e.g., an error 46, from the first graph of the first area 43, as shown in FIG. 9, the first controller 150 may display the second graph indicating location information about the selected state in the second area 45.
Thus, if two graphs are set up to be linked, the user can make sure the second graph dynamically changes according to a condition selected in the first graph.
Meanwhile, if the item 32 selected in FIG. 6 or 8 can not be grouped or linked, i.e., set up to “0” in the conditional data of Table 2, the first controller 150 controls the display 120 to generate and display a message 60 indicating that grouping and linking are impossible, as shown in FIG. 10.
The message 60 of FIG. 10 may include buttons 61 and 62 to select whether to replace the graphic area 40 with a graph of a data corresponding to the newly selected item 32.
If the user selects an OK 61 to replace with the new data through the message 60 of FIG. 10, the first controller 150 determines whether the newly selected item 32 is graphicalizable with reference to the information of Table 1, and controls the display 120 to generate and display a new graph accordingly, as shown in FIG. 11.
If the user selects a cancel 62 to maintain an existing graph through the message 60 of FIG. 10, the first controller 150 controls the display 120 to keep an existing graph displayed, as shown in FIG. 6 or 8.
Meanwhile, the host apparatus 100 of an embodiment may be realized to divide the graphic area 40 into the first area 43 and the second area 45 and to display an existing graph and a graph of the newly selected item 32, respectively, even if the newly selected item 32 in FIG. 6 or 8 cannot be grouped and linked with the existing graph.
Here, the display 120 may display a message to select one of displaying a plurality in the graphic area 40 divided, replacing with a new graph, and maintaining an existing graph.
Meanwhile, if the conditional data on whether grouping and linking are possibly as in Table 2 is stored in the server 200, which is provided separately, when a user selects any one item 32 to be added in FIG. 6 or 8, the first controller 150 controls the first communication unit 140 to load the conditional data on whether grouping and linking are possible from the server 200 and the display 120 to display a UI of any of FIGS. 7, 9 and 10 on the basis of the loaded conditional data.
Accordingly, the host apparatus 100 displays a data of an image forming apparatus by items easily graphicalized by integrated application software such as the web solution and makes sure a plurality of items by dynamically changing them according to whether grouping or linking is possible, thereby providing a user with facilitation in controlling the image forming apparatus.
Hereinafter, a process of the host apparatus 100 displaying information in the image forming system 10 with the foregoing configuration will be described with reference to FIG. 12.
As shown in FIG. 12, the host apparatus 100 receives a data of the image forming apparatus 300-1, 300-2, . . . , and 300-n from at least one connectable image forming apparatus 300-1, 300-2, . . . , and 300-n or the server 200 (S10). Here, the host apparatus 100 may receive a data of the image forming apparatus 300-1, 300-2, . . . , and 300-n responding to execution of the web solution.
The host apparatus 100 displays a UI screen including the data area 30 and the graphic area 40 on the display 120 on the basis of the received data at S10 (S11).
A user selects any one item in the data area 30, i.e., a column, on the UI screen displayed at S11 (S12).
The user selects addition of the item selected at S12 to the graphic area 40 (S13). Here, the user transfers the column selected at S13 to the graphic area 40 by drag-and-drop to be added to the graphic area 40. However, the selected method is not limited thereto.
The first controller 150 determines whether a data of the item selected at S13 is graphicalizable (S14—FIG. 13). Here, the first controller 150 may load the conditional data on graphicalization (see Table 1) stored in the first storage unit 130 or the server 200 to determine to graphicalize.
If determining that graphicalization is possible at S14, the first controller 150 determines whether there is any graph in the graphic region 40 (S15).
If determining that there is a graph at S15, the first controller 150 determines whether the existing graph and the graph selected to be added to the graphic area at S13 can be grouped (S16). Here, the first controller 150 may load the conditional data on grouping and linking (see Table 2) stored in the first storage unit 130 or the server 200 to determine to group.
If determining that grouping is possible at S16, the first controller 150 controls the display 120 to group, i.e., integrate, the existing graph and the graph selected to be added at S13 and to display one graph in the graphic area 40 as shown in FIG. 7 (S17).
If determining that grouping is impossible at S16, the first controller 150 determines whether the existing graph and the graph selected to be added at S13 can be linked (S18). Here, the first controller 150 may load the conditional data on grouping and linking (see Table 2) stored in the first storage unit 130 or the server 200 to determine to group, as at S16, and stages S16 and S18 may be carried out simultaneously.
If determining that linking is possible at S18, the first controller 150 controls the display 120 to display the existing graph and the added graph to be linked in the divided areas 43 and 45 in the graphic area 40, respectively (S19).
If determining that linking is impossible at S18, the user may select whether to divide the graphic area 40 and to display the existing graph and the added graph in the divided graphic area 40 (S20).
If selecting the graphic area 40 to be divided at S20, the first controller 150 controls the display 120 to display the existing graph and the added graph in the divided areas 43 and 45 in the graphic area 40, respectively (S21). Here, the plurality of graphs displayed are not linked to each other unlike the graphs at S20.
If selecting the graphic area 40 is not to be divided at S20, the first controller 150 displays a message 60 to select whether to renew the current graphic area 40 with the graph of the data of the item selected to be added at S13, and the user selects whether to renew corresponding to the displayed message 60 (S22).
If selecting to renew the graphic area 40, the first controller 150 controls the display 120 to display the graph corresponding to the data of the item selected to be added at S13 in the graphic area 40 (S23).
Meanwhile, if determining there is no graph at S15, the first controller 150 controls the display 120 to display the graph corresponding to the data of the item selected to be added at S13 in the graphic area 40 (S23).
In addition, if determining the data of the item selected at S14 cannot be graphicalized, the first controller 150 controls the display 120 to display a message 50 informing the user of this (S24).
As described above, the host apparatus connected to an image forming apparatus and the information offering method thereof according to the present inventive concept provide a user with convenience in facilitating graph reprocessing and data expansion as the user needs with regard to a web solution or an application to control information of the image forming apparatus.
Although a few exemplary embodiments have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these exemplary embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
