  The narrowing of the visual field means a state where the visual field is narrowed. The narrow field of view makes it difficult to fit the entire object within the field of view. Therefore, what is drawn in large size characters and images, etc. included on the screen displayed on the operation panel of a display or image forming apparatus connected to a PC (Personal Computer) etc. It becomes difficult to judge.

  Conventionally, an interface centered on voice has been proposed so that a blind user can handle an operation panel of an electronic device (for example, Patent Document 1).

In addition, a technique has been devised in which a wide range can be looked over by collecting light from the outside world using a convex mirror and projecting it in an effective field of view (for example, Patent Document 2).
JP 2003-76476 A JP 2006-280807 A

  However, the voice interface has problems such as poor operation efficiency and troublesome adjustment in accordance with the characteristics of each user's voice. There is also a problem that the remaining field of view cannot be effectively utilized.

  On the other hand, the method of narrowing light from the outside world has a problem that it requires a pair of special devices attached to both eyes or interferes with existing forcing devices (glasses or the like).

  The present invention has been made in view of the above points, and an object thereof is to provide an information processing apparatus, a display control method, and a program capable of displaying a display screen that is easy to use for a person with narrowed visual field. To do.

  Therefore, in order to solve the above problem, the present invention provides visual field information acquisition means for acquiring visual field information indicating the size of the visual field of the operator with respect to the display area of the display device, and a display screen to be displayed on the display device. Screen generating means for generating a display according to the size of the display, and display control means for displaying the display screen on the display device.

  In such an information processing apparatus, it is possible to display a display screen that is easy to use for a person with narrowed visual field.

  According to the present invention, it is possible to display a display screen that is easy to use for a person with narrowed visual field.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In this embodiment, an image forming apparatus will be described as an example of an information processing apparatus.

  FIG. 1 is a diagram illustrating a hardware configuration example of an image forming apparatus according to an embodiment of the present invention. In FIG. 1, the image forming apparatus 10 includes hardware such as a controller 11, a scanner 12, a printer 13, a modem 14, a network interface 15, and an operation panel 16.

  The controller 11 includes a CPU 111, a RAM 112, a ROM 113, an HDD 114, and the like. The ROM 113 stores various programs and data used by the programs. The RAM 112 is used as a storage area for loading a program, a work area for the loaded program, and the like. The CPU 111 realizes various functions by processing a program loaded in the RAM 112. The HDD 114 records programs and various data used by the programs.

  The scanner 12 is hardware for reading image data from a document. The printer 13 is hardware for printing image data on printing paper. The modem 14 is hardware for connecting to a telephone line, and is used to execute transmission / reception of image data by FAX communication. The network interface 15 is hardware for connecting to a network (regardless of wired or wireless) such as a LAN (Local Area Network). The operation panel 16 is hardware including an input device such as a button and a display device such as a liquid crystal panel 17.

  FIG. 2 is a diagram illustrating a functional configuration example of the image forming apparatus according to the first embodiment. In the figure, the image forming apparatus 10 includes a visual field information acquisition unit 121, a display screen generation unit 122, a display control unit 123, an input reception unit 124, an operation item determination unit 125, a processing control unit 126, a visual field region candidate data 140, And screen configuration data 150 and the like. These units are realized by processing that the program causes the CPU 111 to execute.

  The visual field information acquisition unit 121 acquires information (visual field information) indicating the size of the visual field of the operator with respect to the display area (displayable area) of the liquid crystal panel 17. In the first embodiment, the visual field information acquisition unit 121 acquires visual field information of an operator using visual field region candidate data 140 in which visual field information is registered for each visual field size candidate. The visual field candidate data 140 is stored in the HDD 114, for example.

  The display screen generation unit 122 generates a display screen to be displayed on the liquid crystal panel 17 (for example, an operation screen for operating the image forming apparatus 10) with a size corresponding to the visual field information. The display screen generation unit 122 generates position information and size information of each display item (display component etc.) on the generated display screen as display screen data 160 in the RAM 112. The display screen configuration information is defined in the screen configuration data 150. The screen configuration data 150 is created for each display screen and is stored in the HDD 114, for example.

  The display control unit 123 causes the liquid crystal panel 17 to display the display screen by writing the generated display screen image in the video memory.

  The input receiving unit 124 receives an input to the liquid crystal panel 17 and determines the input position. That is, in the present embodiment, it is assumed that the liquid crystal panel 17 is a touch panel. However, an operation on the display screen may be input by another pointing device such as a mouse.

  The operation item determination unit 125 determines a display item to be operated on the display screen based on the coordinate information indicating the input position determined by the input reception unit 124 and the display screen data 160. Here, the operation includes various operations by the operator on the display screen such as an instruction or selection.

  The process control unit 126 controls execution of a process according to a display item (operation item) that is an operation target.

  Hereinafter, a processing procedure of the image forming apparatus 10 of the first embodiment will be described. FIG. 3 is a flowchart for explaining a processing procedure of the image forming apparatus according to the first embodiment.

  In step S101, the visual field information acquisition unit 121 acquires information (visual field information) indicating the size of the visual field region of the operator. Specifically, the visual field information acquisition unit 121 generates a visual field region selection screen based on the visual field region candidate data 140 and causes the display control unit 123 to display the visual field region selection screen on the liquid crystal panel 17.

  FIG. 4 is a diagram illustrating an example of visual field region candidate data. In this embodiment, the visual field candidate data 140 is defined in an XML (eXtensible Markup Language) format. However, it may be defined by other formats such as CSV (Comma Separated Values). The same applies to various data described below.

  The field-of-view area candidate data 140 in the figure uses a view element surrounded by <views> tags as a root element. Each view element included in the views element indicates information corresponding to a visual field region candidate (hereinafter referred to as “visual field region candidate”). In the figure, four view elements 141 to 144 are defined. Therefore, four visual field area candidates are defined.

  Each view element includes a number element and a rate element. The value of the number element is an identification number of each visual field region candidate. The value of the rate element indicates the size of the visual field area by the ratio (%) to the display area of the liquid crystal panel 17.

  The visual field information acquisition unit 121 generates a visual field area selection screen including a graphic indicating the visual field area candidate based on the visual field area candidate data 140 in FIG.

  FIG. 5 is a diagram illustrating a display example of the visual field region selection screen. In the visual field area selection screen 171 in FIG. 5, figures (rectangles) corresponding to the respective visual field area candidates are displayed in left-justified order in the definition order of the visual field area candidate data 140. The width (horizontal direction) length of each rectangle is calculated by multiplying the width of the display area 170 of the liquid crystal panel 17 by the value of the rate element. The height (vertical length) of each rectangle is calculated by multiplying the height of the display area 170 by the value of the rate element. In each rectangle, the identification number of the corresponding visual field region candidate is displayed. It is assumed that the width and height of the display area 170 are known. For example, the width and height of the display area 170 are recorded in the HDD 114 or the ROM 113.

  On the visual field area selection screen 171, the operator selects a rectangle that matches his visual field (for example, all or most of it fits in the visual field at once). The visual field information acquisition unit 121 uses the selected rectangular width and height as visual field information corresponding to the operator.

  Subsequently, the display screen generation unit 122 acquires the screen configuration data 150 and expands it in the RAM 112 (S102).

  FIG. 6 is a diagram illustrating an example of screen configuration data. In the figure, image configuration data 150 relating to a display screen having setting items (display items) for setting the print quality, the number of prints, and the printing method is shown.

  The screen configuration data 150 in FIG. 6 uses a settings element surrounded by <settings> tags as a root element. Each setting element included in the settings element indicates information regarding each setting item (display item) on the display screen. A setting element 151 corresponds to the print quality. A setting element 152 corresponds to the number of printed sheets. A setting element 153 corresponds to a printing method.

  Each setting element has a name attribute and a type attribute. The value of the name attribute is the name of the setting item, and is a character string displayed as a label. The value of the type attribute indicates the type of the setting value. In the figure, SELECT and VALUE are exemplified. SELECT indicates that the value of any element element in the setting element can be selected as a setting value. VALUE indicates that a value within the range specified by the value of the element element in the setting element can be set.

  Each setting element includes a note element. The value of the note element is a character string indicating a detailed description of the setting item. However, in the first embodiment, the note element is not a display target.

  Subsequently, the display screen generation unit 122 generates an image of the display screen with a default size based on the screen configuration data 150 (S103). Here, the default size refers to a size in which all display items fit within the display area 170 in as large a size as possible. However, the position information (for example, upper left coordinates) and size information (for example, width and height) of each display item may be included in the screen configuration data 150 as default size information. In this case, the display screen generation unit 122 generates a display screen having a default size based on the size information included in the screen configuration data 150.

  Subsequently, the display screen generation unit 122 scales (reduces) the image (display image) on the display screen based on the visual field information (S104). For example, the display image is reduced so that the whole or most of the display screen (for example, a threshold value of 90% or more) is within the visual field area. For the scaling process, for example, a bicubic method may be used. The bicubic method is a digital image processing algorithm that determines colors for each pixel of a reduced image by mixing colors of neighboring points at positions corresponding to the image before reduction.

  The display screen generation unit 122 converts the position information and size information of each display item according to the scaling, and generates the conversion result in the RAM 112 as display screen data 160. That is, the display screen data 160 includes position information and size information of each display item on the reduced display screen.

  Subsequently, the display control unit 123 displays the scaled display screen at a predetermined position (for example, the center) of the display area 170 by writing the scaled display image in the video memory (S105).

  FIG. 7 is a diagram illustrating a display example of the display screen according to the first embodiment. (A) of the figure is a display example of the display screen when the display screen is scaled according to the visual field information. (B) is a display example of the display screen when the display screen is not scaled by the visual field information (that is, when the display screen is displayed with the default size). An ellipse v in the display area 170 of both (A) and (B) indicates the visual field area of the operator. In the figure, the visual field region when the visual field region candidate with the identification number “1” is selected is shown.

  As shown in FIG. 5A, according to the present embodiment, the display screen can be scaled and displayed in accordance with the size of the visual field area of the operator. Therefore, the operator can grasp the entire display screen at a glance within his field of view. As a result, the operability of the display screen can be improved.

  In the above description, the example in which the image on the entire display screen is reduced after the display screen is generated with the default size has been described. However, the display screen (each display item) may be generated in advance at a position and size that match the size of the visual field area. In this case, it is not necessary to reduce the generated display screen image. This also applies to the following embodiments.

  By the way, when an operation instruction is input by the operator on the display screen displayed as shown in FIG. 7A, the input receiving unit 124 displays coordinate information indicating a position where the operation instruction is generated in the display area 170. Input to the operation item determination unit 125. The operation item determination unit 125 determines a display item that is an operation instruction target based on the coordinate information and the display screen data 160. Therefore, even when the display screen is reduced, it is possible to appropriately determine the display item to be operated (without causing a deviation from the operator's recognition).

  By the way, in the first embodiment, the size of the visual field region can be selected only from predetermined sizes. Therefore, an example in which such a point has been improved will be described as a second embodiment. Note that points not particularly mentioned in the second embodiment may be the same as those in the first embodiment.

  In the second embodiment, the processing by the visual field information acquisition unit 121 is different. FIG. 8 is a flowchart for explaining a processing procedure by the visual field information acquisition unit in the second embodiment. The process of FIG. 11 is executed instead of step S101 of FIG.

  In step S201, the visual field information acquisition unit 121 displays a screen for instructing the visual field region (hereinafter referred to as “visual field region instruction screen”) on the display region 170, and corresponds to the visual field region on the visual field region instruction screen ( For example, the operator is instructed to indicate one vertex (first point) of a virtual rectangle (including all or most of the visual field area). The visual field information acquisition unit 121 holds the coordinate value of the instructed position.

  Subsequently, the visual field information acquisition unit 121 instructs the operator to designate a vertex (second point) diagonal to the point designated as the first point in the virtual rectangle corresponding to the visual field region. (S202).

  Subsequently, the visual field information acquisition unit 121 sets the size information of a rectangle having the first point and the second point specified by the operator as vertices of diagonal positions as visual field information corresponding to the operator (S103). Thereafter, the same processing as step S102 and subsequent steps in FIG. 3 is executed based on the visual field area. However, the display screen may be displayed not at the center of the display area 170 but at a rectangular position designated by the operator.

  As described above, according to the image forming apparatus 10 in the second embodiment, the display screen can be displayed with a size that is more suitable for the visual field region of the operator. The visual field information may be acquired by instructing three or more points. For example, in the case of three points, the circle itself specified by the three points or a rectangle inscribed in the circle may be used as the visual field region. If there are four points, a quadrangle specified by the four points may be used as the visual field region.

  Next, a third embodiment will be described. Points that are not particularly mentioned in the third embodiment may be the same as those in the first or second embodiment.

  FIG. 9 is a diagram illustrating a functional configuration example of the image forming apparatus according to the third embodiment. 9, the same parts as those in FIG. 2 are denoted by the same reference numerals, and the description thereof is omitted.

  In the third embodiment, the image forming apparatus 10 has partial area definition data 180. The partial area definition data 180 is data including definition information related to the partial area on the display screen, and is stored in the HDD 114, for example. The partial area refers to each divided area when the display screen is divided according to some standard. In the present embodiment, it is assumed that the display screen has a partial area in which setting items are displayed and a partial area in which explanatory text relating to the setting items is displayed.

  FIG. 10 is a flowchart for explaining the processing procedure of the image forming apparatus according to the third embodiment.

  Step S301 is the same as step S101 of FIG. 3 or FIG. Subsequently, the display screen generation unit 122 acquires the partial area definition data 180 and expands it in the RAM 112 (S302).

  FIG. 11 is a diagram illustrating an example of partial area definition data. The partial area definition data 180 in FIG. 6 uses an area element surrounded by <areas> tags as a root element. Each area element included in the area element indicates information regarding each partial area. Each area element includes a content element. The value of the content element indicates information to be displayed in the partial area. For example, in the figure, the value of the content element of the area element 181 is “element”. Therefore, it can be seen that display items (setting items) corresponding to the element element of the screen definition data 150 are displayed in the partial area. The value of the content element of the area element 182 is “note”. Therefore, it can be seen that a display item (description) corresponding to the note element of the screen definition data 150 is displayed in the partial area. In the following description, the area element is referred to as “partial area information”.

  Subsequently, the display screen generation unit 122 selects one of the partial area information included in the partial area definition data 180 as a processing target (S303). Subsequently, the display screen generation unit 122 acquires display information corresponding to the selected partial region information from the screen definition data 150 (S304). Specifically, when the value of the content element of the partial area information is “element”, the value of each attribute (name, type) of each setting element of the screen definition data 150 and the value of each element element are acquired. To do. On the other hand, when the content value of the partial area information is “note”, each “note” element of the screen definition data 150 is acquired. Subsequently, the display screen generation unit 122 generates a partial region image (partial region image) based on the acquired display information (S305). At this time, the partial area is generated with a default size. Steps S304 to S305 are executed for all partial area information defined in the partial area definition data 180.

  Subsequently, the display screen generating unit 122 scales each generated partial region image based on the visual field information (S307). Here, scaling is performed so that all or most of the partial area images can be accommodated in the visual field area.

  Subsequently, the display control unit 123 initializes the count variable to 0 (S308). Subsequently, the display control unit 123 selects one of the scaled partial area images as a processing target (S309). Subsequently, the display control unit 123 moves the partial region image to a position where the partial region image is moved to the left by (num−1) × width / 2−count × width from the position where the partial region image is arranged at the center of the display region 170. Is displayed in the display area 170.

  Here, width is the width of the viewing area, and num is the number of partial areas.

  The display control unit 123 executes Steps S309 and S310 for all partial region images (S311). At this time, the display control unit 123 increments the value of the count variable for each partial area (S312). Therefore, the next partial area is displayed at a position shifted to the right by the width of the visual field area.

  FIG. 12 is a diagram illustrating a display example of the display screen according to the third embodiment. In FIG. 3, (A) shows a visual field region when the operator moves the viewpoint to the left. At this time, the visual field region v includes a partial region related to the setting item. (B) shows a visual field region when the operator moves the viewpoint to the right. At this time, the visual field region v includes a partial region related to the explanatory text.

  As described above, according to the image forming apparatus 10 in the third embodiment, each partial area can be displayed in a size corresponding to the visual field area. Therefore, for example, an explanatory text for the setting item can be displayed beside the partial area of the setting item. As a result, the operator can easily confirm the explanatory text (detailed information). In the first and second embodiments, the area that was a non-display area can be used effectively.

  In the above description, the example in which the partial areas are arranged in the horizontal direction has been described. This is because the display area 170 of the present embodiment is horizontally long. Therefore, for example, when it is determined that arranging the partial areas in the vertical direction provides better operability, such as when the display area is vertically long, the partial areas may be arranged in the vertical direction. Since the processing procedure in that case is obvious from FIG.

  By the way, in the case of the third embodiment, there may be a partial region that protrudes beyond the display region 170 depending on the size of the visual field region.

  FIG. 13 is a diagram illustrating an example in which the partial area protrudes from the display area. In the same figure, since the horizontal width of the visual field area exceeds half of the display area, the left side of the partial area related to the setting item and the right side of the partial area related to the explanatory text protrude from the display area 170, respectively. As a result, the screen information of the protruding part is missing.

  Therefore, an example in which such a problem is solved will be described as a fourth embodiment. Note that points not particularly mentioned in the fourth embodiment may be the same as those in the third embodiment.

  FIG. 14 is a flowchart for explaining the processing procedure of the image forming apparatus according to the fourth embodiment. In FIG. 14, the same steps as those in FIG. 10 are denoted by the same step numbers, and the description thereof is omitted. In FIG. 14, steps S307a and S307b are added after step S307.

  In step S307a, the display screen generation unit 122 determines whether the width of the visual field area × the number of partial areas / the width of the display area is greater than 1.0 (S307a). That is, it is determined whether or not all the partial area images that have been scaled according to the visual field area fit in the display area 170 in the horizontal direction. Here, the width of the visual field area × the number of partial areas / the value of the display area is referred to as “lateral ratio”. When the determination is negative (No in S307a), the display screen generation unit 122 reduces each partial area image based on the horizontal ratio (S307b). That is, the width and height of the image of each partial area are divided by the horizontal ratio. As a result, the display screen displayed as shown in FIG. 13 is displayed as shown in FIG.

  FIG. 15 is a diagram illustrating a display example of a display screen according to the fourth embodiment. In the figure, all partial areas are within the display area 170.

  As described above, according to the image forming apparatus 10 of the fourth embodiment, the display screen can be displayed so that all the partial areas are within the display area 170. In this case, the size of each partial area is smaller than the visual field area. Therefore, all of the partial areas can be accommodated in the visual field area of the operator.

  Similarly, when the partial areas are arranged in the vertical direction, each partial area may be reduced based on the vertical ratio (the height of the visual field area × the number of partial areas / the height of the display area).

  By the way, when the display screen is reduced in accordance with the visual field area, characters, icons, etc. in the display screen become too small, and there is a possibility that the visibility is deteriorated. Thus, in the fifth embodiment, an example in which such a problem is solved will be described. In the fifth embodiment, points not particularly mentioned may be the same as those in the first to fourth embodiments.

  FIG. 16 is a flowchart for explaining the processing procedure of the image forming apparatus according to the fourth embodiment.

  Steps S501 and S502 are the same as steps S101 and S102 in FIG. Note that step S501 may be replaced with FIG.

  Subsequently, the display screen generation unit 122 selects one display item information (setting element) in the screen configuration definition data 150 as a processing target (S503). Subsequently, the display screen generation unit 122 generates a display image (display item image) of the display item based on the display item information to be selected (S504). At this time, the display item image is generated with a default size. Subsequently, the display screen generation unit 122 scales (reduces) the display item image based on the visual field information (S505). For example, the display item image is scaled so that all or most of the display item image is included in the visual field region. Steps S503 to S505 are executed for all display item information (setting elements) (S506).

  When the generation and scaling of all the display item images are completed (NO in S506), the display control unit 123 displays a display screen including all the display item images in the display area 170 (S507).

  FIG. 17 is a diagram illustrating a display example of the display screen according to the fifth embodiment. In the figure, each display item (setting item) is displayed in the size of the visual field area. Within each display item, soft keys indicated by (+) and (−) are arranged. The operator can select or change the setting value by the soft key.

  If there are display items that extend beyond the display area 170, processing similar to that described in the fourth embodiment may be executed.

  As described above, according to the image forming apparatus 10 in the fifth embodiment, since characters, icons, etc. of each display item can be displayed large, the visibility of the characters, icons, etc. can be improved. it can.

  Next, a sixth embodiment will be described. The points not particularly mentioned in the sixth embodiment may be the same as those in the fifth embodiment.

  FIG. 18 is a diagram illustrating a display example of the display screen according to the sixth embodiment. In the figure, soft keys for each display item are displayed outside each display item. That is, for each of the print quality, the number of prints, and the print method, soft keys for selecting or changing the respective set values are displayed above and below each display item. By doing so, characters and the like in each display item can be displayed in a large size, and soft keys can be displayed in a large size. As a result, the visibility and operability of each display item can be further improved.

  The display screen generation process as shown in FIG. 18 is obvious from FIG. That is, it is only necessary to generate a display image independently for the element element as well as each setting element in the screen configuration definition data 150 and scale the display image according to the visual field area.

  By the way, when the display screen is reduced and displayed in a part of the display area 170 as in the first embodiment, it takes time for the operator of visual constriction to find the part. There is such a possibility. Therefore, a seventh embodiment will be described as an example in which such problems are solved.

  FIG. 19 is a diagram illustrating a functional configuration example of the image forming apparatus according to the seventh embodiment. In FIG. 19, the same parts as those in FIG.

  In FIG. 1, the image forming apparatus 10 includes a guide generation unit 127. The guide generation unit 127 generates a guide symbol (an arrow in the present embodiment) indicating the position where the display screen is displayed in the display area 170.

  FIG. 20 is a flowchart for explaining the processing procedure of the image forming apparatus according to the seventh embodiment. The process of FIG. 9 is executed after the process of FIG. 3 (that is, after the display screen is displayed).

  In step S601, the guide generation unit 127 calculates the coordinate value of the center position of the display screen (for example, the intersection of diagonal lines). This calculation may be performed based on the display screen data 160, for example. Subsequently, the guide generation unit 127 generates virtual rectangles (hereinafter referred to as “cells”) from the center position of the display screen in the vertical and horizontal directions at equal intervals (cell height and width intervals) (S602). ). The width of the cell is a half of the width of the viewing area. The height of the cell is one half of the height of the viewing area.

  Subsequently, the guide generation unit 127 selects one of the generated cells as a processing target (S603). Subsequently, the guide generation unit 127 determines whether an image on the display screen is displayed in the selected cell (S604). The determination may be performed based on the display screen data 160 or may be performed by referring to an address corresponding to the cell in the video memory.

  Subsequently, when an image is not displayed in the cell (NO in S604), the guide generation unit 127 generates an arrow indicating the center of the display screen in the cell (S605). The processing after step S603 is executed for all cells (S606). As a result, the display contents in the display area 170 are as shown in FIG.

  FIG. 21 is a diagram illustrating a display example in the display area according to the seventh embodiment. As shown in the figure, an arrow indicating the center of the display screen is displayed in each cell arranged in a portion where the display screen is not displayed. In addition, in the same figure, the outer periphery of each cell is displayed by the solid line, However, The line which shows the said outer periphery does not necessarily need to be displayed. Further, the size of each cell may not be half of the viewing area. As long as an arrow is drawn in the maximum size in each cell, the size of the cell may be the same as the viewing area (that is, it may be smaller than the viewing area). This is because even if it is the same as the visual field region, it is possible to almost always guide the operator of the visual field narrowing. Further, the shape of the guide need not be an arrow. Anything can be used as long as the direction can be identified, such as a triangle.

  As described above, according to the image forming apparatus 10 of the seventh embodiment, a guide indicating the position of the display screen can be displayed by effectively utilizing the area where the display screen is not displayed. Therefore, the operator can quickly find the display screen.

  In the above embodiment, the example in which the present invention is applied to the image forming apparatus 10 has been described. This is because the display position and size of the display screen of an electronic device such as the image forming apparatus 10 are fixed and suitable for the implementation of the present invention.
