Description

  The present invention relates to a display control device and a display control program.

  Information displayed on the display device may be difficult for the user to see. As an example, there are a case where a font of a character displayed on the display device is small or a case where the content displayed on the display device is fine.

  In such a case, the user performs an operation of enlarging the size (size) of the image displayed on the display device. For example, the user sets an enlarged display of the display image in an application that provides the display image, or sets the resolution of the display image to be small.

  Here, there is a technique for automatically performing enlarged display without the user himself / herself performing an operation. As an example, there is a technique of Patent Document 1 in which display is performed with the character size increased in accordance with the amount of characters displayed on the display device. As another example, a user's fatigue state is estimated based on measurement data measured by an electroencephalogram transmitter or a biological data transmitter, and the size or resolution of an image displayed on the display device is changed according to the fatigue state. There is a technique of Patent Document 2.

  However, both of the above-described techniques of Patent Document 1 and Patent Document 2 have a problem that enlarged display cannot be performed when necessary with a simple configuration.

  For example, the technique of the above-mentioned Patent Document 1 is merely a method for making the character size correspond to the amount of characters included in the image to be displayed. For this reason, in the technique of Patent Document 1, any user who views the display device displays an enlarged image when displaying an image having a predetermined amount or more of characters. However, such an enlarged display is not necessarily a display that matches individual characteristics such as age and fatigue. Therefore, the technique of Patent Document 1 cannot perform enlarged display when necessary for the user.

  Moreover, although the technique of patent document 2 can change a display mode according to a fatigue state, exclusive hardware (hardware) will be needed in order to collect a user's biometric data. Therefore, the technique of Patent Document 2 cannot automatically perform enlarged display with a simple configuration.

  The disclosed technology has been made in view of the above, and an object thereof is to provide a display control device and a display control program capable of executing enlarged display when necessary with a simple configuration.

  The display control device disclosed in the present application includes a reception unit that receives selection of a screen from an input device. Further, the display control device outputs the selected screen to a display device, and causes the display device to display an enlarged screen obtained by enlarging a part or all of the output screen or a reduced reduced screen. Have Furthermore, the display control device includes a measuring unit that measures an operation speed of a user who operates the input device. Furthermore, the display control device includes a comparison unit that compares the measured operation speed with a predetermined value. Furthermore, the display control device includes a generation unit that generates a command to make the selected screen the enlarged screen or the reduced screen based on the comparison result.

  According to one aspect of the display control device disclosed in the present application, there is an effect that enlarged display can be executed when necessary with a simple configuration.

  Embodiments of a display control device and a display control program disclosed in the present application will be described below in detail with reference to the drawings. Note that this embodiment does not limit the disclosed technology. Each embodiment can be appropriately combined within a range in which processing contents are not contradictory.

  FIG. 1 is a block diagram illustrating the configuration of the display control apparatus according to the first embodiment. The display control device 1 shown in FIG. 1 accepts various instruction inputs on the screen displayed on the display device 1b via the input device 1a, and is enlarged especially to make it easier for the user to see the screen being displayed. Display or reduction display automatically.

  As shown in FIG. 1, the display control device 1 includes an attribute storage unit 1c, a condition storage unit 1d, a reception unit 1e, a determination unit 1f, a measurement unit 1g, a comparison unit 1h, a generation unit 1j, And an output unit 1k.

  Among these, the attribute memory | storage part 1c matches and memorize | stores the identification information and attribute which identify a screen. That is, the attribute storage unit 1c defines a correspondence between one or a plurality of screen IDs and attribute IDs for uniquely specifying attributes classified based on the screen contents.

  Here, “screen ID” refers to identification information for uniquely identifying a screen. However, when the contents of the screen are the same, the same screen ID is assigned between the screens having different resolutions. Note that, here, when the screen contents are the same, the same screen ID is assigned, but it is also possible to assign a screen ID for each screen content and resolution. Further, “attribute ID (identity)” refers to identification information for uniquely specifying an attribute of a screen.

  Examples of such attributes include a “text screen” including characters, symbols, images, and the like in addition to a “menu screen” including a plurality of options in the screen. In this way, a plurality of screen IDs are associated with a single attribute to identify contents that are included in the screen, such as fonts of characters and symbols, buttons having similar sizes and layouts, etc. Because.

  The condition storage unit 1d stores, for each piece of identification information for identifying an attribute, an operation speed condition that triggers execution of enlarged display or reduced display during display of a screen having the attribute. FIG. 2 is a diagram illustrating a configuration example of information stored in the condition storage unit. In the example of FIG. 2, it is assumed that enlargement display or reduction display is automatically performed on a menu screen that displays options on the screen. Furthermore, in the example of FIG. 2, it is assumed that a screen having the same content is prepared for each attribute for each of the three resolutions of high resolution, medium resolution, and low resolution. Note that the resolution is an index indicating the fineness of the screen and the smoothness of the image quality. For example, when the same content is expressed with the same image quality, the lower the resolution, the larger the display size (size).

  As illustrated in FIG. 2, the condition storage unit 1 d stores an attribute ID, a resolution, an operation speed, and a change destination in association with each other. Here, the “operation speed” refers to the speed of an operation performed by the user via the input device 1a, and examples thereof include a selection time and a scroll speed. Among these, the selection time indicates an elapsed time from a certain time point as a starting point. As an example of the starting point of such selection time, there is a point in time when a transition is made to a new screen on one screen. An example of the end point of the selection time is a point in time when one of the menus and items displayed on the screen is selected by the user. That is, the selection time is measured until the selection operation by the user is performed. For example, the measurement unit measures the time required to select one of input fields such as body temperature and blood pressure on the nursing record input screen. When there are a plurality of input fields, the time from when input to each input field is completed until the next input field is selected is measured as the selection time. The scroll speed indicates the width of the area in which the screen scrolls within a predetermined period. When a plurality of screens are displayed on the display device 1b, a selection time or a scroll speed is measured for each screen by a measurement unit 1g described later. In addition, the measurement of the selection time and the scroll speed is measured by the measurement unit 1g described later only during a period when the screen operation is valid, that is, during a period when the screen is active. The “change destination” refers to the resolution of the screen displayed after the change when the resolution of the currently displayed screen is changed.

  In the example of FIG. 2, it is stipulated that the same content is displayed on the three screens having the attribute ID “001” of high resolution, medium resolution, and low resolution, although the screen resolutions are different. In these three screens for each resolution, the condition of the operation speed that triggers a change to a screen with another resolution and the resolution to be changed are defined for each resolution. Such operation speed conditions and the resolution of the change destination are defined according to the following logic. For example, when the selection time is long or the scroll speed is slow, it can be estimated that characters, symbols, images, etc. displayed on the screen are too small. In this case, the resolution is changed to a resolution lower than the resolution of the screen being displayed. In addition, when the selection time is long and the scrolling speed is fast, it can be estimated that characters, symbols, images, etc. displayed on the screen are too large and the entire screen cannot be viewed. In this case, the resolution is changed to a resolution higher than the resolution of the screen being displayed.

  For example, a description will be given of the operation speed condition and the change destination resolution when the screen being displayed has a high resolution. In the example of the high resolution screen shown in FIG. 2, when the selection time measured by the measurement unit 1g described later is a predetermined period or longer, or when the scroll speed is lower than the predetermined speed, the medium resolution screen is displayed. It is prescribed to change. Here, the case where one of the selection time and the scrolling speed satisfies the condition has been described, but the display control apparatus 1 disclosed is not limited to this. For example, the high resolution may be changed to the medium resolution when the selection time is equal to or longer than a predetermined period and the scroll speed is equal to or lower than the predetermined speed.

  In addition, an operation speed condition and a change destination resolution when the screen being displayed has a medium resolution will be described. In the example of the medium resolution screen shown in FIG. 2, the screen is changed to a high resolution screen when the selection time measured by the measurement unit 1g described later is longer than a predetermined period and the scroll speed is higher than the predetermined speed. It is prescribed to do. Furthermore, in the example of the medium resolution screen shown in FIG. 2, the low resolution screen is displayed when the selection time measured by the measurement unit 1g described later is equal to or longer than a predetermined period and the scroll speed is equal to or lower than the predetermined speed. It is prescribed to change to.

  In addition, an operation speed condition and a change destination resolution when the screen being displayed has a low resolution will be described. In the example of the low resolution screen shown in FIG. 2, when the selection time measured by the measurement unit 1g described later is longer than a predetermined period and the scroll speed is higher than the predetermined speed, the screen is changed to a medium resolution screen. It is prescribed to do.

  Returning to the description of FIG. 1, the reception unit 1 e receives a screen selection from the input device 1 a. For example, when the screen being displayed is a menu screen, an operation of selecting one or more items from the plurality of items to which buttons, tabs, and icons are assigned is accepted via the input device 1a.

  The determination unit 1f determines the attribute of the screen received by the reception unit 1e using the attribute storage unit 1c. As an example, if the selection unit 1e receives a selection of a new screen transition or a selection of switching a screen to be activated, the determination unit 1f is a screen of a newly transitioned screen or a newly activated screen. Specify the ID. Then, the determination unit 1f determines an attribute ID corresponding to the screen ID specified earlier among the attribute IDs stored in the attribute storage unit 1c.

  The measuring unit 1g measures the operation speed of the user who operates the input device 1a. The measurement unit 1g does not measure the operation speed related to the same type of operation for all the attributes of the screen. That is, the measurement unit 1g changes the type of operation to be measured according to the attribute ID determined by the determination unit 1f.

  For example, the following description will be given assuming that the attribute ID determined by the determination unit 1f is “001” shown in FIG. In this case, both the click and scroll conditions for the high resolution, medium resolution, and low resolution are defined by the condition storage unit 1d. In this case, the determination unit 1f determines that both click and scroll are the types of operations to be measured regardless of whether the resolution is high resolution, medium resolution, or low resolution.

  In the example of FIG. 2, the case where the conditions relating to both the selection time and the scroll speed are defined in any of the high resolution, medium resolution, and low resolution screens with the attribute ID “001” is illustrated. The disclosed display control apparatus 1 is not limited to this. That is, the condition storage unit 1d can arbitrarily define a condition relating to either the selection time or the scroll speed for each resolution. For example, when only the selection time is defined as the operation speed condition, the measurement unit 1g determines that the click is the type of operation to be measured. Further, when the scroll speed is defined as the operation speed condition, the measuring unit 1g determines that the type of operation has scroll as a measurement target.

  After determining the type of operation to be measured in this way, the measuring unit 1g measures the operation speed corresponding to the type of operation to be measured. For example, when the type of operation to be measured is click, the measurement unit 1g measures the elapsed time after transitioning to a new screen as the selection time. When the type of operation to be measured is scroll, the measurement unit 1g measures the ratio of the width of the screen scrolling with respect to the elapsed time after transitioning to a new screen as the scroll speed. If the type of operation to be measured is both click and scroll, both the selection time and the scroll speed are measured.

  The comparison unit 1h compares the operation speed measured by the measurement unit 1g with a predetermined value. As an example, it is assumed that a high-resolution screen with the attribute ID “001” is being displayed. In this case, the comparison unit 1h reads out the selection time and the scroll speed corresponding to the high resolution among the operation speed conditions stored in the condition storage unit 1d. Then, the comparison unit 1h compares the selection time measured by the measurement unit 1g with the selection time read from the condition storage unit 1d. The comparison unit 1h compares the scroll speed measured by the measurement unit 1g with the scroll speed read from the condition storage unit 1d.

  The generation unit 1j generates a command for setting the screen being displayed on the display device 1b to be an enlarged screen or a reduced screen based on the comparison result by the comparison unit 1h. For example, when a comparison result is obtained that the selection time measured by the measurement unit 1g is equal to or longer than the selection time read from the condition storage unit 1d, the high-resolution screen being displayed is displayed with the same screen ID. Generate a command to change to a medium resolution screen with. Similarly, when a comparison result is obtained in which the scroll speed measured by the measurement unit 1g is equal to or lower than the scroll speed read from the condition storage unit 1d, a medium resolution screen having the same screen ID is obtained. Generate instructions to change. In this way, when a command for reducing the resolution is generated with the screen having the same content, the display size of the screen displayed on the display device 1b increases, and as a result, the screen is enlarged.

  The output unit 1k outputs the screen selected by the receiving unit 1e to the display device 1b. Further, the output unit 1k causes the display device 1b to display an enlarged screen or a reduced screen obtained by enlarging or reducing a part or all of the screen in accordance with an instruction from the generating unit 1j. For example, when a command for changing from a high-resolution screen to a medium-resolution screen is generated by the generation unit 1j, the screen output to the display device 1b is changed from a high-resolution screen to a medium-resolution screen.

[Effect of Example 1]
As described above, the display control apparatus 1 according to the present embodiment changes to an enlarged screen or a reduced screen according to the operation speed of the user measured through the input device 1a. For this reason, in the display control apparatus 1 according to the present embodiment, display contents such as characters, symbols, and images included in the screen can be displayed in a size suitable for the operation characteristics of the user. In addition, the display control apparatus 1 according to the present embodiment does not require special hardware for measuring the operation speed of the user. That is, the display control apparatus 1 according to the present embodiment estimates the user's fatigue state and visual ability without receiving a signal from a device that measures the user's fatigue state and visual ability, etc. The display suitable for can be performed. Therefore, according to the display control apparatus 1 according to the present embodiment, it is possible to execute enlarged display when necessary with a simple configuration.

  In addition, the display control apparatus 1 according to the present embodiment changes the type of operation to be measured according to the screen attribute. For this reason, in the display control apparatus 1 according to the present embodiment, the operation speed can be measured for the type of operation that matches the attribute of the screen being displayed. That is, in the display control apparatus 1 according to the present embodiment, even when the type of operation expected by the user is different for each screen, the operation speed and the predetermined value are uniformly compared on all screens. It will never be. Therefore, according to the display control apparatus 1 according to the present embodiment, it is possible to prevent an enlarged display or a reduced display that is uncomfortable for the user.

  Furthermore, the display control apparatus 1 according to the present embodiment determines the attribute by referring to the attribute storage unit 1c that stores the identification information for identifying the screen and the attribute in association with each other. For this reason, the display control apparatus 1 according to the present embodiment can identify content that is similar to the content included in the screen, for example, the font of characters and symbols, the size and layout of buttons, and the like. Therefore, according to the display control apparatus 1 according to the present embodiment, it is possible to reduce the amount of information for controlling the enlarged display or the reduced display.

  Further, the display control device 1 according to the present embodiment generates a command for enlarging or reducing a part or all of the screen, and outputs an enlarged screen or a reduced screen generated based on the command to the display device 1b. For this reason, in the display control apparatus 1 according to the present embodiment, it is possible to execute enlarged display or reduced display targeting a display area that the user pays attention in the display area of the display apparatus 1b. Therefore, the display control apparatus 1 according to the present embodiment can prevent the display area from being enlarged or reduced to a display area that is not always difficult for the user to visually recognize. Therefore, according to the display control apparatus 1 according to the present embodiment, it is possible to maintain the visibility other than the display area of the screen while improving the visibility of the display area of the screen.

  Subsequently, a display control apparatus according to the second embodiment will be described. In this embodiment, it is assumed that a screen generated by an application (application software) that supports medical care at a medical institution is displayed in an enlarged or reduced manner.

[System configuration]
Subsequently, a medical assistance system according to the present embodiment will be described. FIG. 3 is a system configuration diagram illustrating a configuration of a medical assistance system according to the second embodiment. As shown in FIG. 3, a medical assistance system (system) 3 accommodates a plurality of medical assistance clients 10 </ b> A to 10 </ b> C and a medical assistance server 30. In the example of FIG. 3, three medical assistance clients and one medical assistance server are illustrated, but the disclosed system is not limited to the illustrated configuration. That is, the medical assistance system 3 can accommodate any number of medical assistance clients and medical assistance servers.

  The medical assistance clients 10 </ b> A to 10 </ b> C and the medical assistance server 30 are connected to each other via a network 5 so that they can communicate with each other. The network 5 may be any type of communication network such as the Internet (Internet), a LAN (Local Area Network), or a VPN (Virtual Private Network), regardless of wired or wireless.

  The medical assistance clients (clients) 10A to 10C are client terminals used by medical personnel. As one aspect of the medical assistance clients 10A to 10C, a fixed terminal such as a personal computer (PC) or a server can be employed. In addition to these fixed terminals, mobile terminals such as mobile phones, PHS (Personal Handyphone System) and PDA (Personal Digital Assistant) can be adopted. The medical personnel mentioned above include medical employees such as doctors, nurses, pharmacists, and laboratory technicians, as well as office workers and system maintenance personnel. Hereinafter, the medical support clients 10 </ b> A to 10 </ b> C are collectively referred to as the medical support client 10 when collectively referred to without distinction.

  The medical support client 10 is installed with applications that support various work related to medical care such as management of a patient's profile, filling in a medical chart, filling in an order of medicines and tests, and filling in nursing records ( install). Hereinafter, an application installed in the medical support client 10 is referred to as a client medical support application.

  In the medical support client 10, a medical support application for a client is activated when a medical person logs in to the system with his / her own account. After such login, the client medical assistance application downloads from the medical assistance server 30 a screen master in which display control related to the screen is defined together with the screen used by the client. Thereafter, the client medical assistance application generates a necessary screen in accordance with an operation received via the input unit 11 described later, and displays the generated screen on the display unit 12 described later.

  The medical assistance server 30 is a server device that provides the medical assistance system 10 to the medical assistance client 10 that is a client terminal. The medical care support server 30 has various data bases such as patient profiles, medical records, various orders, and nursing records. In addition, a medical support application for servers is installed in the medical support server 30, and the server medical support application provides the functions of the medical support system 3 to the medical support client 10 through the client medical support application.

  Explaining this, when receiving a login request together with authentication information such as a user ID and a password (password) from the medical support client 10, the medical support server 30 executes login authentication. Then, when the login authentication is successful, the medical assistance server 30 transmits a screen master in which display control related to the screen is defined to the medical assistance client 10 together with a screen used by the medical assistance application for client. Thereafter, the medical assistance server 30 provides the function of the medical assistance system 3 by releasing resources stored in various databases according to the logged-in account.

[Composition of medical assistance client]
Next, the configuration of the medical assistance client included in the medical assistance system 3 according to the present embodiment will be described. FIG. 4 is a block diagram illustrating the configuration of the medical assistance client according to the second embodiment. The medical assistance client 10 illustrated in FIG. 4 includes an input unit 11, a display unit 12, a communication I / F unit 13, a storage unit 14, and a control unit 15. Note that the medical assistance client 10 includes various functional units included in a known computer other than the functional units illustrated in FIG. 4, for example, voice devices such as a voice input unit and a voice output unit.

  Among these, the input unit 11 is an input device that receives various types of information, for example, an instruction input to a client medical assistance application 15a described later, and a keyboard or a mouse can be applied as an example. Note that the display unit 12 described later also realizes a pointing device function in cooperation with the mouse.

  The display unit 12 is a display device that displays various kinds of information, for example, an image generated by a client medical support application 15a described later, and examples thereof include a monitor, a display, and a touch panel (touch panel). ) Etc. can be applied.

  The communication I / F unit 13 is an interface for performing communication with other apparatuses such as the medical assistance server 30 and other medical assistance clients 10.

  The storage unit 14 is, for example, a semiconductor memory device such as a flash memory, or a storage device such as a hard disk or an optical disk. The storage unit 14 is not limited to the above type of storage device, and may be a RAM (Random Access Memory) or a ROM (Read Only Memory).

  The storage unit 14 stores various programs such as an OS (Operating System) executed by the control unit 15 and a later-described client medical support application 15a. Further, the storage unit 14 stores data necessary for executing the program executed by the control unit 15, for example, screen data used for the client medical assistance application. In addition, the storage unit 14 also stores the screen master 14a.

  The screen master 14a is master data in which display control related to the screen is defined. As an aspect of the screen master 14a, the screen ID, resolution, storage location, operation speed condition, and change destination resolution are stored in association with each other. The “storage location” here refers to a location where screen data used by a client medical assistance application 15a described later is stored. The screen master 14a is downloaded from the server medical support application when a client medical support application 15a described later is started.

  FIG. 5 is a diagram illustrating an example of the screen master. The screen master 14a shown in FIG. 5 defines the operation speed condition for each screen ID, unlike the condition storage unit 1d shown in FIG. 2 in which the operation speed condition is defined for each attribute ID. Thereby, in the screen master 14a shown in FIG. 5, the type of operation to be measured by the operation measuring unit 15d described later can be set for each screen, and the threshold value to be compared with the measured value can be set for each screen.

  First, the menu screen of the screen ID “MWNU001” shown in FIG. 5 will be described. As shown in FIG. 5, three menu screens of high resolution, medium resolution, and low resolution are prepared as the screen with the screen ID “MWNU001”. These three resolution menu screens are specified to display the same contents, although the resolutions differ between the screens. The menu screen for each resolution is stored in a folder “MWNU001” in a folder “XXX” in the D drive. Among these, when generating a high-resolution menu screen, the file “high” is called by the output control unit 15g described later. Further, when generating a medium resolution menu screen, the file “middle” is called by the output control unit 15g described later. When generating a low-resolution menu screen, the file “low” is called by the output control unit 15g described later. Here, the case where the storage location is described using the absolute path (path) in which the route from the root directory or drive to the target screen is described has been described, but the relative path is used. It doesn't matter.

  In these three menu screens with the screen ID “MWNU001”, the resolution of the display unit 12 and the operation speed conditions for changing the screen resolution and the resolution to be changed are defined for each resolution. In the following, the operation speed condition and the change destination resolution defined on the menu screen of each resolution will be described with reference to FIGS. 6A to 6C.

  FIG. 6A is a diagram illustrating an example of a high-resolution menu screen. FIG. 6B is a diagram illustrating an example of a medium resolution menu screen. FIG. 6C is a diagram illustrating an example of a low-resolution menu screen. Reference numeral 40 shown in FIG. 6A indicates a high-resolution menu screen. Reference numeral 50 shown in FIG. 6B indicates a medium resolution menu screen. Reference numeral 60 shown in FIG. 6C indicates a low-resolution menu screen. Reference numerals 51a and 61a shown in FIGS. 6B and 6C indicate scroll buttons for scrolling the menu screen 50 or the menu screen 60 upward. Reference numerals 51b and 61b shown in FIGS. 6B and 6C indicate scroll buttons for scrolling the menu screen 50 or the menu screen 60 downward. Reference numerals 52 and 62 shown in FIGS. 6B and 6C denote a scroll bar that is scrolled in the moving direction of the mouse by a mouse drag operation, a mouse wheel operation, or a keyboard up / down key. Point to.

  The high-resolution menu screen 40 shown in FIG. 6A is designed so that all selection buttons displayed on the screen fit within the screen when displayed at a certain size, for example, the full screen. That is, in the menu screen 40, selection buttons included in the large items “sharing”, “maintenance”, “patient information”, “outpatient management”, “ward management”, “global cooperation”, and “medical record” with shading Are all within the screen. Furthermore, on the menu screen 40, all the selection buttons included in the small items “Web reference” and “clinical research support” are within the screen. For this reason, in the menu screen 40, the medical staff using the medical assistance client 10 does not need to perform an operation related to scrolling.

  The high-resolution menu screen 40 defines an operation speed condition for reducing the resolution. In the example of FIG. 5, it is defined that the resolution of the display unit 12 and the resolution of the screen are changed to a medium resolution when the selection time measured by the operation measurement unit 15d described later is 3 seconds or more. . This is because the menu screen 40 does not need to be scrolled, so that the characters displayed as items and the characters displayed in the selection buttons are small and may be difficult for the user to see. Thus, when the selection time of the menu screen 40 is long, it is estimated that characters, symbols, images, and the like displayed on the screen are too small for the user according to the rules of the screen master 14a. Note that the threshold of the selection time to be compared with the measurement value can be set according to the contents included in the screen, or can be set for each user.

  Further, the medium resolution menu screen 50 shown in FIG. 6B has a lower resolution than the high resolution menu screen 40. For this reason, the medium resolution menu screen 50 has the advantage that the content is displayed larger than the high resolution menu screen 40, but also has the disadvantage that the entire screen cannot be viewed without scrolling. The medium resolution menu screen 50 includes all the same selection buttons as the high resolution menu screen 40, but the screen layout is changed so that the entire contents of the screen can be browsed by a vertical scroll operation. That is, selection buttons included in the small items “Web reference” and “clinical research support” are arranged below the large item “maintenance”.

  The medium resolution menu screen 50 defines both an operation speed condition for reducing the resolution and an operation speed condition for increasing the resolution. Both the condition for reducing the resolution and the condition for increasing the resolution are defined as a requirement that the selection time measured by the operation measurement unit 15d described later is 3 seconds or more.

  As described above, when the selection time of the menu screen 50 is long, it is estimated that the medium resolution is not suitable by the user, and the change destination of the resolution is not defined only by the condition regarding the selection time. This is because a plurality of causes are assumed as a cause of delaying selection of the menu screen 50. As an example, the characters, symbols and images displayed on the screen are small for the user. Another example is that it is difficult to find a target selection button because the entire screen cannot be viewed without scrolling. If the cause of delaying selection of the menu screen 50 is the former, it is preferable to lower the resolution, but if it is the latter, it is preferable to increase the resolution.

  For this reason, in the menu screen 50 of medium resolution, the increase or decrease of the resolution is defined by the magnitude of the scroll speed. For example, when the scroll speed is 1.5 times / second or more, it is defined that the resolution of the display unit 12 and the screen resolution are changed to a high resolution. This is because in this case, the scroll operation is repeated more than necessary, and it is possible to estimate a situation in which the user cannot look down on the entire screen. On the other hand, when the scroll speed is less than 1.5 times / second, it is defined that the resolution of the display unit 12 and the screen resolution are changed to a low resolution. In this case, it takes more time than necessary to grasp the entire menu screen 50, and it can be estimated that characters, symbols, images, etc. displayed on the screen are small for the user at medium resolution. is there. Note that the threshold of the scroll speed to be compared with the measured value can also be set according to the contents included in the screen, or can be set for each user.

  Further, the low resolution menu screen 60 shown in FIG. 6C has a lower resolution than the medium resolution menu screen 50. For this reason, the low-resolution menu screen 60 has an advantage that the contents are displayed larger than the medium-resolution menu screen 50, while more scrolling is required to view the entire screen than the medium-resolution menu screen 50. It also has the disadvantage of requiring The low-resolution menu screen 60 includes all the same selection buttons as the high-resolution menu screen 40 and the medium-resolution menu screen 50, but the screen layout is such that the entire contents of the screen can be viewed by a vertical scroll operation. has been edited. That is, compared to the high-resolution menu screen 40, the large item “medical record” is arranged below the large item “maintenance”. Furthermore, the large item “Earth cooperation” is arranged below the large item “patient information”. Further, selection buttons included in the small items “Web reference” and “clinical research support” are arranged below the large item “ward management”.

  The low resolution menu screen 60 defines the conditions for operating speed to increase the resolution. In the example of FIG. 5, when the selection time measured by the operation measurement unit 15d described later is 3 seconds or more and the scroll speed is 1.5 times / second or more, the resolution of the display unit 12 and It is specified to change the screen resolution to medium resolution. This is because in this case, the low-resolution display is not suitable for the user, and the scrolling operation is repeated more than necessary, so that it is possible to estimate the situation where the user cannot see the entire screen. .

  In the screen examples of FIGS. 6A to 6C, the case where the selection operation is performed on the menu screen 40, 50, or 60 is illustrated as a transition to the screen for the button on which the selection operation has been performed. It is not limited to this. For example, the disclosed apparatus can be applied to a case where a plurality of selection operations are received on one screen. In this case, the disclosed apparatus measures, as the selection time, an elapsed time after the screen transitions each time a selection operation is performed or since the previous selection operation was performed. For example, when there are a plurality of input fields such as body temperature and blood pressure on the nursing record input screen, the disclosed apparatus until the next input field is selected after the input to each input field is completed. Is measured as the selected time.

  Next, the text screen with the screen ID “text001” shown in FIG. 5 will be described. As shown in FIG. 5, three text screens of high resolution, medium resolution, and low resolution are prepared as the screen with the screen ID “text001”. These three resolution text screens are specified to display the same contents, although the resolutions differ between the screens. Each resolution text screen is stored in a folder “text001” in a folder “XXX” in the D drive. Among these, when generating a high-resolution text screen, the file “high” is called by the output control unit 15g described later. When generating a medium resolution text screen, the file “middle” is called by the output control unit 15g described later. In addition, when generating a low resolution text screen, the file “low” is called by the output control unit 15g described later.

  The text screen of each resolution shown in FIG. 5 does not define conditions regarding the selection time. The reason why the condition regarding the selection time is not specified in the text screen is that the text screen is mainly a description of characters, symbols, etc., and the user reads the information rather than accepting the request for the system from the user. This is because the screen is focused on. On the other hand, conditions regarding the scrolling speed are defined for text screens of each resolution. This is because if there is much content included in the text screen, a scroll operation occurs even if a selection operation does not occur.

  For example, for a high-resolution text screen, when the scroll speed measured by the operation measurement unit 15d described later is less than 0.3 times / second, the resolution of the display unit 12 and the screen resolution are changed to medium resolution. It is prescribed. Thus, when the scroll speed of the text screen is slow, it is estimated that characters, symbols, images, and the like displayed on the screen are too small for the user according to the rules of the screen master 14a.

  In addition, both a scroll speed condition for reducing the resolution and a scroll speed condition for increasing the resolution are defined for the medium resolution text screen. For example, when the scroll speed measured by an operation measurement unit 15d described later is less than 0.3 times / second, it is specified that the resolution of the display unit 12 and the screen resolution are changed to a low resolution. Thus, when the scroll speed of the text screen is slow, it can be estimated that the display size of the content of the medium resolution text screen is too small. On the other hand, when the scroll speed measured by the operation measuring unit 15d described later is 2 times / second or more, it is defined that the resolution of the display unit 12 and the screen resolution are changed to a high resolution. Thus, when the scroll speed of the text screen is high, the scroll operation is repeated more than necessary on the medium resolution text screen, and it is possible to estimate a situation in which the user cannot look down on the entire screen.

  Further, when the scroll speed measured by the operation measuring unit 15d described later is 2 times / second or more on the low-resolution text screen, the resolution of the display unit 12 and the screen resolution are changed to medium resolution. Is stipulated. As described above, when the scroll speed of the text screen is fast, the scroll operation is repeated more than necessary on the low-resolution text screen, and it is possible to estimate a situation where the user cannot look down on the entire screen.

  The control unit 15 is, for example, an integrated circuit such as an application specific integrated circuit (ASIC) or a field programmable gate array (FPGA) or an electronic circuit such as a central processing unit (CPU) or a micro processing unit (MPU).

  The control unit 15 has an internal memory for storing programs defining various processing procedures and control data, and executes various processes using these. As shown in FIG. 4, the control unit 15 includes a client medical support application 15a, an operation reception unit 15b, a logic determination unit 15c, an operation measurement unit 15d, a comparison unit 15e, a command generation unit 15f, and an output. And a control unit 15g.

  Among these, the client medical assistance application 15 a is a processing unit that provides the medical assistance client 10 with the functions of the medical assistance system 3. As an example, the client medical assistance application 15a is activated when a medical person logs in to the system with his / her own account. After logging in to the system, the client medical support application 15a downloads the screen master in which display control related to the screen is defined together with the screen data used by the client from the medical support server 30 via the server medical support application. The screen master downloaded in this manner is registered in the storage unit 14 as the screen master 14a. Thereafter, the client medical assistance application 15a receives screen generation request information for requesting screen generation according to an operation received via the input unit 11 described later, for example, information such as a screen ID, characters to be embedded in the screen, symbols, images, and the like. It outputs to the output control part 15g mentioned later.

  Here, in this embodiment, a high-resolution screen is displayed for all users immediately after login, and when the display unit 12 and the screen resolution are changed thereafter, the screen is changed even after the screen transition. The following description will be made on the assumption that the resolution is inherited as the display target resolution. Here, a case has been described in which a high-resolution screen is displayed for all users immediately after login, but it is not always necessary to use high resolution as the default for display immediately after login. As an example, the resolution to be displayed for each user may be set in the medical support server 30 as a user master, and the display unit 12 and the screen resolution displayed immediately after login may be changed for each user. .

  The operation accepting unit 15 b is a processing unit that accepts screen selection via the input unit 11. As an example, when the displayed screen is a menu screen, the operation reception unit 15b performs a click operation, an Enter key pressing operation, or the like from among a plurality of items to which buttons, tabs, icons, and the like are assigned. Accept an operation to select one or more items. By such a selection operation, the currently displayed screen is changed to a new screen, or a new screen is generated separately from the currently displayed screen. As another example, when a plurality of screens are displayed on the display unit 12, the operation reception unit 15 b also receives an operation for switching an active screen, that is, an active screen through a click operation or the like. .

  The logic determination unit 15c is a processing unit that uses the screen master 14a to determine monitoring logic that causes the operation measurement unit 15d and the comparison unit 15e to monitor the operation speed.

  Explaining this, when the operation accepting unit 15b accepts an operation for a new screen transition or a selection to switch an active screen, the logic determination unit 15c creates a newly transitioned screen or a newly activated screen. The screen ID is specified. After that, the logic determination unit 15c has the operation speed corresponding to the screen ID specified earlier and the resolution applied to the current display among the operation speed conditions stored as the screen master 14a in the storage unit 14. Read the condition. At this time, the logic determination unit 15c specifies the type of operation to be measured by the operation measurement unit 15d from the operation speed specified as the condition. Furthermore, the logic determination unit 15c specifies the comparison contents defined as the operation speed condition, that is, the threshold value and the comparison method. Then, the logic determination unit 15c assembles the monitoring logic based on the comparison content to be compared with the type of operation to be measured and the operation speed.

  For example, assume that the monitoring logic of the high-resolution menu screen shown in FIG. 6A is assembled. In this example, the logic determination unit 15c uses the condition “selection time 3 seconds as the operation speed condition corresponding to the high resolution menu screen 40 with the screen ID“ MWNU001 ”from the screen master 14a illustrated in FIG. Read “that is above”. And since the operation speed prescribed | regulated as conditions is the selection time, the logic determination part 15c specifies that the kind of operation which the operation measurement part 15d measures is a click. In addition, the logic determination unit 15c specifies the threshold “3 seconds” and the comparison method “above” defined as the conditions related to the selection time. In addition, the logic determination unit 15c includes monitoring logic that defines a procedure for causing the operation measurement unit 15d to measure the selection time and a procedure for causing the comparison unit 15e to determine whether the measurement value of the selection time is 3 seconds or more. assemble.

  Further, it is assumed that the monitoring logic of the medium resolution menu screen shown in FIG. 6B is assembled. In this example, the logic determination unit 15c uses the condition “selection time 3 seconds as the operation speed condition corresponding to the medium resolution menu screen 50 of the screen ID“ MWNU001 ”from the screen master 14a shown in FIG. Read “that is above”. Further, the logic determination unit 15 c similarly reads the conditions regarding the scroll speed “the scroll speed is 1.5 times / second or more” and “the scroll speed is less than 1.5 times / second”. And since the operation speed prescribed | regulated as conditions is the selection time and the scroll speed, the logic determination part 15c specifies that the kind of operation which the operation measurement part 15d measures is a click and a scroll. Further, the logic determination unit 15c compares the threshold value “3 seconds” and the comparison method “above” defined as the conditions related to the selection time, and the threshold value “1.5 times / second” and the comparison defined as the conditions related to the scroll speed. Identify the method “more than or less than”. In addition, the logic determination unit 15c defines a procedure for causing the operation measurement unit 15d to measure the selection time and the scroll speed. Furthermore, the logic determination unit 15c defines a procedure for causing the comparison unit 15e to determine whether the measured value of the selection time is 3 seconds or more. Further, the logic determination unit 15c defines a procedure for causing the comparison unit 15e to determine whether or not the measured value of the scroll speed is less than 1.5 times / second. Then, the logic determination unit 15c assembles monitoring logic including the above three procedures.

  Assume that the monitoring logic of the low-resolution menu screen shown in FIG. 6C is assembled. In this example, the logic determination unit 15c uses the condition “selection time 3 seconds as the operation speed condition corresponding to the low resolution menu screen 60 of the screen ID“ MWNU001 ”from the screen master 14a shown in FIG. Read “that is above”. Further, the logic determination unit 15 c similarly reads the condition regarding the scroll speed “the scroll speed is 1.5 times / second or more”. And since the operation speed prescribed | regulated as conditions is the selection time and the scroll speed, the logic determination part 15c specifies that the kind of operation which the operation measurement part 15d measures is a click and a scroll. Further, the logic determination unit 15c compares the threshold value “3 seconds” and the comparison method “above” defined as the conditions related to the selection time, and the threshold value “1.5 times / second” and the comparison defined as the conditions related to the scroll speed. Specify the method “more”. In addition, the logic determination unit 15c defines a procedure for causing the operation measurement unit 15d to measure the selection time and the scroll speed. Furthermore, the logic determination unit 15c defines a procedure for causing the comparison unit 15e to determine whether the measured value of the selection time is 3 seconds or more. Furthermore, the logic determination unit 15c defines a procedure for causing the comparison unit 15e to determine whether or not the measured value of the scroll speed is 1.5 times / second or more. Then, the logic determination unit 15c assembles monitoring logic including the above three procedures.

  Here, the case where the monitoring logic of the menu screen of each resolution is assembled has been described, but the monitoring logic of the text screen of each resolution shown in FIG. 5 can also be assembled in the same manner.

  The operation measurement unit 15d is a processing unit that measures the operation speed according to the monitoring logic assembled by the logic determination unit 15c. For example, when click is defined as the type of operation to be measured, the operation measurement unit 15d measures the elapsed time after transition to a new screen as the selection time. Note that the operation measurement unit 15d may select the selection time because the user may not be willing to operate when the mouse cursor has been stopped for a predetermined period during the measurement of the selection time. It is good also as clearing (clear) and re-measurement.

  When scrolling is defined as the type of operation to be measured, the operation measuring unit 15d determines the ratio of the width of the screen scrolling with respect to the elapsed time since the transition to the new screen. Measure as As an example of measuring the scrolled width, the operation measurement unit 15d includes the number of operations of the upward scroll buttons 51a and 61a and the number of operations of the downward scroll buttons 51b and 61b illustrated in FIGS. 6B and 6C. Measure. As another example, the operation measuring unit 15d measures the number of operations of the scroll bars 52 and 62 shown in FIGS. 6B and 6C. As a further example, the operation measurement unit 15d measures the amount of rotation of the mouse wheel. In the case of measuring the scroll width, the number of operations of the scroll buttons 51a and 61a in the upward direction and the number of operations of the scroll buttons 51b and 61b in the downward direction may be added together. The number of upward operations may be subtracted.

  Here, when a plurality of screens are displayed on the display unit 12, the operation measurement unit 15d measures the selection time or the scroll speed for each screen. At this time, the operation measurement unit 15d sets only an active screen as a measurement target. That is, the operation measurement unit 15d interrupts the measurement of the selection time and the scroll speed for screens other than the active screen, and resumes the measurement of the selection time and the scroll speed when it becomes active.

  The comparison unit 15e is a processing unit that compares the operation speed measured by the operation measurement unit 15d with the threshold acquired from the screen master 14a in accordance with the monitoring logic assembled by the logic determination unit 15c.

  As an example, in the case of the monitoring logic corresponding to the menu screen 40 illustrated in FIG. 6A, the comparison unit 15e determines whether the selection time measured by the operation measurement unit 15d is equal to or greater than a threshold value.

  As another example, in the case of the monitoring logic corresponding to the menu screen 50 shown in FIG. 6B, the comparison unit 15e determines whether or not the selection time measured by the operation measurement unit 15d is equal to or greater than a threshold value. . And when the selection time which is a measured value is more than a threshold value, the comparison part 15e further determines whether the scroll speed measured by the operation measurement part 15d is less than a threshold value.

  As a further example, in the case of the monitoring logic corresponding to the menu screen 60 shown in FIG. 6C, the comparison unit 15e determines whether or not the selection time measured by the operation measurement unit 15d is equal to or greater than a threshold value. . And when the selection time which is a measured value is more than a threshold value, the comparison part 15e further determines whether the scroll speed measured by the operation measurement part 15d is more than a threshold value.

  The command generation unit 15f is a processing unit that generates a command for changing the resolution of the display unit 12 and the resolution of the screen being displayed based on the comparison result by the comparison unit 15e.

  As an example, a case is assumed where the monitoring logic corresponding to the menu screen 40 shown in FIG. 6A is being activated. At this time, if the measurement value of the selection time is equal to or greater than the threshold value, the command generation unit 15f generates a command to change the resolution of the display unit 12 and the resolution of the screen ID “MWNU001” from high resolution to medium resolution.

  As another example, assume that the monitoring logic corresponding to the menu screen 50 shown in FIG. 6B is being activated. At this time, if the measurement value of the selection time is equal to or greater than the threshold value and the measurement value of the scroll speed is less than the threshold value, the command generation unit 15f sets the resolution of the display unit 12 and the resolution of the screen ID “MWNU001” to the middle. Generate instructions to change from resolution to low resolution. When the measurement value of the selection time is equal to or greater than the threshold value and the measurement value of the scroll speed is equal to or greater than the threshold value, the command generation unit 15f sets the resolution of the display unit 12 and the resolution of the screen ID “MWNU001” to the medium resolution. Generate an instruction to change from to high resolution.

  As a further example, assume that the monitoring logic corresponding to the menu screen 60 shown in FIG. 6C is being activated. At this time, if the measurement value of the selection time is equal to or greater than the threshold value and the measurement value of the scroll speed is equal to or greater than the threshold value, the instruction generation unit 15f reduces the resolution of the display unit 12 and the resolution of the screen ID “MWNU001”. Generate an instruction to change from resolution to medium resolution.

  The output control unit 15g is a processing unit that performs output control on the display unit 12. For example, the output control unit 15g generates various screens related to the medical support system 3, such as a menu screen and a text screen, in response to the screen generation request information output by the client medical support application 15a.

  Further, the output control unit 15g changes the resolution of the display unit 12 and the resolution of the screen being displayed to the resolution specified by the previous command in accordance with the command generated by the command generation unit 15f.

  As an example, it is assumed that the monitoring logic corresponding to the menu screen 40 illustrated in FIG. 6A is being activated. At this time, when a command for changing from high resolution to medium resolution is generated by the command generation unit 15f, the output control unit 15g changes the resolution of the display unit 12 from high resolution to medium resolution. At the same time, the output control unit 15g changes the high resolution menu screen 40 shown in FIG. 6A to the medium resolution menu screen 50 shown in FIG. 6B. As described above, when the screen is replaced, the output control unit 15g changes the input value input in the form included in the menu screen 40 being displayed or the image inserted in the image tag to the change destination menu screen. You can take over to 40.

  As another example, it is assumed that the monitoring logic corresponding to the menu screen 50 illustrated in FIG. 6B is being activated. At this time, if a command for changing from the medium resolution to the low resolution is generated by the command generation unit 15f, the output control unit 15g changes the resolution of the display unit 12 from the medium resolution to the low resolution. At the same time, the output control unit 15g changes the medium resolution menu screen 50 shown in FIG. 6B to the low resolution menu screen 60 shown in FIG. 6C. Further, when a command for changing from the medium resolution to the high resolution is generated by the command generation unit 15f, the output control unit 15g changes the resolution of the display unit 12 from the medium resolution to the high resolution. At the same time, the output control unit 15g changes the medium resolution menu screen 50 shown in FIG. 6B to the high resolution menu screen 40 shown in FIG. 6A.

  As a further example, a case is assumed where the monitoring logic corresponding to the menu screen 60 shown in FIG. 6C is being activated. At this time, if a command for changing from low resolution to medium resolution is generated by the command generation unit 15f, the output control unit 15g changes the resolution of the display unit 12 from low resolution to medium resolution. At the same time, the output control unit 15g changes the low resolution menu screen 60 shown in FIG. 6C to the medium resolution menu screen 50 shown in FIG. 6B.

[Process flow]
Next, the process flow of the medical assistance system according to the present embodiment will be described. Here, the (1) overall flow executed by the medical assistance client 10 will be described. After that, as an example of a sub-flow executed in the case of a menu screen, (2) operation speed monitoring processing for high resolution, (3) operation speed monitoring processing for medium resolution, (4) for low resolution The operation speed monitoring process will be described in this order.

(1) Overall Flow FIG. 7 is a flowchart illustrating a procedure of an overall flow executed by the medical assistance client according to the second embodiment. This overall flow is activated when the client medical assistance application 15a successfully logs in to the medical assistance system 3.

  As shown in FIG. 7, when the login to the system is successful (step S101), the client medical assistance application 15a downloads the screen master from the medical assistance server 30 via the server medical assistance application (step S102).

  Thereafter, the logic determination unit 15c first accesses the page such as the main menu screen if it is immediately after login, or if it is not immediately after login, the screen ID of the newly transitioned screen or newly activated screen Is specified (step S103).

  And the logic determination part 15c sets the operation speed condition corresponding to the resolution applied to the previously specified screen ID and the current display among the operation speed conditions stored as the screen master 14a in the storage unit 14. Read (step S104).

  Subsequently, the logic determination unit 15c specifies the type of operation to be measured by the operation measurement unit 15d from the operation speed specified as the condition, and the comparison contents specified as the operation speed condition, that is, the threshold value and the comparison method Is specified (step S105).

  And the logic determination part 15c assembles monitoring logic based on the comparison content compared with the classification and operation speed of operation made into measurement object (step S106).

  Thereafter, when an operation for changing the screen or a selection for switching the active screen is accepted (Yes at Step S107 or Yes at Step S108), the process proceeds to Step S103.

  Further, when the operation for changing the screen or the selection for switching the active screen is not accepted (No at Step S107 and No at Step S108), the following processing is executed. That is, the operation speed monitoring process is executed based on the monitoring logic assembled in step S106 (step S109).

  Note that after the operation speed monitoring process is executed, the process proceeds to step S107. The processes in steps S103 to S109 are repeatedly executed until all the screens related to the client medical assistance application 15a are closed.

(2) Operation Speed Monitoring Process for High Resolution FIG. 8 is a flowchart illustrating the procedure of the operation speed monitoring process for high resolution according to the second embodiment. 8 is a process corresponding to the operation speed monitoring process of step S109 in the overall flow shown in FIG. 7, and is a process executed when the monitoring logic of the menu screen 40 shown in FIG. 6A is assembled. is there.

  As illustrated in FIG. 8, the operation measurement unit 15d measures the elapsed time after transition to a new screen as the selection time (step S201). And the comparison part 15e determines whether the selection time measured by the operation measurement part 15d is more than a threshold value (step S202).

  At this time, if the measurement value of the selection time is equal to or greater than the threshold value (Yes at Step S202), the command generation unit 15f changes the resolution of the display unit 12 and the resolution of the screen ID “MWNU001” from high resolution to medium resolution. An instruction is generated (step S203), and the process ends.

  If the measured value of the selection time is less than the threshold (No at Step S202), it can be estimated that the current resolution is suitable for the user, and thus the process is terminated without executing the resolution change.

(3) Medium Resolution Operation Speed Monitoring Process FIG. 9 is a flowchart illustrating the procedure of the medium resolution operation speed monitoring process according to the second embodiment. The subflow in FIG. 9 is a process corresponding to the operation speed monitoring process in step S109 in the overall flow shown in FIG. 7, and is a process executed when the monitoring logic of the menu screen 50 shown in FIG. 6B is assembled. is there.

  As shown in FIG. 9, the operation measurement unit 15d measures the elapsed time since the transition to the new screen as the selection time, and measures the ratio of the scroll width to the elapsed time as the scroll speed (step S301).

  Then, the comparison unit 15e determines whether or not the selection time measured by the operation measurement unit 15d is greater than or equal to a threshold value (step S302). At this time, if the measurement value of the selection time is less than the threshold value (No in step S302), it can be estimated that the current resolution is suitable for the user, and thus the process is terminated.

  On the other hand, when the measurement value of the selection time is equal to or greater than the threshold value (Yes at Step S302), the comparison unit 15e further determines whether or not the scroll speed measured by the operation measurement unit 15d is less than the threshold value (Step S302). S303).

  Here, if the measured value of the scroll speed is less than the threshold value (Yes at Step S303), it can be estimated that the display is still small at the current resolution, and therefore the command generation unit 15f performs the following process. That is, the command generation unit 15f generates a command for changing the resolution of the display unit 12 and the resolution of the screen ID “MWNU001” from the medium resolution to the low resolution (step S304), and ends the process.

  On the other hand, when the measured value of the scroll speed is equal to or greater than the threshold value (No in step S303), it can be estimated that the entire screen cannot be viewed from the current resolution, and therefore the command generation unit 15f performs the following process. That is, the command generation unit 15f generates a command for changing the resolution of the display unit 12 and the resolution of the screen ID “MWNU001” from the medium resolution to the high resolution (step S305), and ends the process.

(4) Low Resolution Operation Speed Monitoring Process FIG. 10 is a flowchart illustrating the procedure of the low resolution operation speed monitoring process according to the second embodiment. The subflow in FIG. 10 is a process corresponding to the operation speed monitoring process in step S109 in the overall flow shown in FIG. 7, and is a process executed when the monitoring logic of the menu screen 60 shown in FIG. 6C is assembled. is there.

  As shown in FIG. 10, the operation measurement unit 15d measures the elapsed time since the transition to the new screen as the selection time, and measures the ratio of the scroll width to the elapsed time as the scroll speed (step S401).

  And the comparison part 15e determines whether the selection time measured by the operation measurement part 15d is more than a threshold value (step S402). At this time, if the measured value of the selection time is less than the threshold value (No in step S402), it can be estimated that the current resolution is suitable for the user, and thus the process is terminated.

  On the other hand, when the measurement value of the selection time is equal to or greater than the threshold value (Yes at Step S402), the comparison unit 15e further determines whether or not the scroll speed measured by the operation measurement unit 15d is equal to or greater than the threshold value (Step S402). S403).

  At this time, if the measured value of the scroll speed is equal to or greater than the threshold value (Yes at step S403), it can be estimated that the entire screen cannot be viewed from the current resolution, and therefore the command generation unit 15f performs the following process. That is, the command generation unit 15f generates a command for changing the resolution of the display unit 12 and the resolution of the screen ID “MWNU001” from the low resolution to the medium resolution (step S404), and ends the process. If the scroll speed measurement value is equal to or greater than the threshold value (No at step S403), the process ends.

[Effect of Example 2]
As described above, the medical assistance client 10 according to the present embodiment can display the display contents such as characters, symbols, and images included in the screen in a size suitable for the operation characteristics of the user. In addition, the medical assistance client 10 according to the present embodiment does not require special hardware for measuring the operation speed of the user. Therefore, according to the medical assistance client 10 according to the present embodiment, it is possible to execute an enlarged display when necessary with a simple configuration as in the first embodiment.

  Further, the medical assistance client 10 according to the present embodiment changes the type of operation to be measured depending on whether the displayed screen is a menu screen or a text screen.
