Description

  The present invention relates to a portable information processing apparatus having a function of estimating whether a brain related disease is caused by an erroneous operation of an input operation.

  As a method for inspecting brain abnormalities, there have conventionally been methods such as CT scan of the brain and MRI (magnetic resonance imaging). In this method, a person who felt an abnormality in the brain went to the hospital and examined the internal structure of the brain by X-rays or magnetism.

Further, as a method of examining the brain nerve function, there is a mental function testing method called TMT (Trail-Making-Test). In this method, numbers randomly arranged on a paper surface are connected with a line in order, and the person to be examined determines the state of brain disease based on the time required for this task. Furthermore, as this method is performed by a personal computer, numbers randomly arranged on the touch panel 102 are displayed, and the person receiving the brain diagnosis draws a line in the order of the numbers, and draws a line to the last number. There has been a method of diagnosing the neurological function of the brain by calculating the time and the wrong number of times required to draw (for example, Patent Document 1).
Japanese Patent Laid-Open No. 11-188020

  However, in the method of examining the brain by CT scan, MRI, etc., the person undergoing the examination feels that there is an abnormality in the brain and goes to the hospital to undergo the examination. When I found out, there were cases where brain abnormalities had progressed considerably. This is the same when the brain state is regularly examined by CT scan, MRI or the like.

  In addition, in the mental function testing method called TMT, it is possible to easily diagnose the mental function. However, if the person receiving the diagnosis does not intend to receive the test, the test cannot be performed. It was difficult to easily judge that the function of the system was degraded.

  The present invention uses a portable information processing device for daily use, and in a normal use state of the portable information processing device, there is an abnormality in the brain in an initial state before a brain abnormality (disease) progresses It is an object of the present invention to provide a portable information processing apparatus with a disease tendency estimation function that determines the possibility of a disease and estimates the possibility of having a disease related to the brain (disease tendency).

  According to the first aspect of the present invention, various screen information can be displayed and a display means for displaying an operation location for inputting an instruction for switching screen information is operated within a predetermined range from the operation location. An operation detecting means for detecting whether or not a predetermined range is operated by the operation detecting means, an erroneous operation determining means for determining whether or not the operation is an erroneous operation, and a determination by the erroneous operation determining means Erroneous operation frequency calculation means for calculating the frequency of the erroneous operation performed, erroneous operation frequency storage means for storing the value of the erroneous operation frequency calculated by the erroneous operation frequency calculation means, and past erroneous operations stored in the erroneous operation frequency storage means The average value of the erroneous operation frequency calculating means for calculating the average value of the frequency of the past erroneous operations based on the frequency value of the erroneous operation, and the erroneous operation frequency value calculated by the erroneous operation frequency calculating means and the erroneous operation frequency The comparison means for comparing the disease tendency judgment value obtained from the average value of the past erroneous operation frequency values calculated by the average value calculation means, and as a result of the comparison by the comparison means, the erroneous operation frequency value is the disease tendency When it is higher than the judgment value, it has a disease tendency estimating means for estimating a tendency of a predetermined disease, and an output means for outputting a disease tendency estimation result estimated by the disease tendency estimating means.

  According to a second aspect of the present invention, when the disease tendency estimation means determines that the erroneous operation frequency value is higher than the disease tendency determination value as a result of the comparison by the comparison means, the deviation of the erroneous operation frequency value from the disease tendency determination value. The degree of tendency of a predetermined disease is estimated according to the degree.

  According to a third aspect of the present invention, the erroneous operation determination means determines whether or not the operation immediately before the operation location is operated is also an operation at the operation location for switching screen information. And if the previous operation where the operation location was operated by the screen switching operation determination means is also determined as an operation location operation for switching screen information, the operation location is operated. Cancel operation determination processing for determining whether the screen information after switching and the screen information before the screen information is switched by the previous operation are the same information, and the same information by the cancel operation determination means When it is determined that the operation is incorrect, it is determined that the operation is erroneous.

  According to a fourth aspect of the present invention, the erroneous operation determination means has a cancel key operation determination means for determining whether or not a cancel key for canceling the previous operation has been operated. When it is determined that the key is operated, it is determined that the operation is erroneous.

  According to a fifth aspect of the present invention, the erroneous operation determination means includes an operation location peripheral operation determination means for determining whether or not a predetermined range has been operated from the operation location excluding the operation location, and the operation location peripheral operation is determined. When it is detected by the determining means that an operation within a predetermined range is operated from an operation location excluding the operation location, it is determined that the operation is erroneous.

  The invention according to claim 6 is a case where, by the disease tendency estimation means, when the error operation frequency value is higher than the disease tendency determination value, the deviation degree of the error operation frequency value from the disease tendency determination value is a predetermined value or more. And a disease tendency test processing means for performing a disease tendency test.

  According to the seventh aspect of the present invention, the disease tendency test processing means displays a display location on which a predetermined order is displayed on the display means, and performs an instruction operation in the order of the display locations displayed on the display means. The disease tendency is determined according to the measurement time required to instruct and operate all the display locations, and the output means outputs the determination result of the disease tendency according to the measurement time.

  The invention according to claim 8 is characterized in that the output means outputs data relating to a disease tendency to a network means outside the portable information processing apparatus with a disease tendency estimation function.

  The invention according to claim 9 further includes usage environment determination means for determining whether or not the usage environment of the user is an environment suitable for using the information processing means with a disease tendency estimation function. The means is suitable for using the information processing means when the use environment judging means determines that the user's use environment is not an environment suitable for using the information processing means with a disease tendency estimation function. It is characterized in that an operation within a period determined not to be an environment is not determined as an erroneous operation.

  According to the first aspect of the present invention, in the portable information processing apparatus for daily use, the value of the frequency of erroneous operation obtained from the erroneous operation of the operation location for inputting the instruction for switching the screen information, and the past Compared to the disease tendency judgment value obtained from the average value of the frequency of erroneous operations, and when the value of the frequency of erroneous operations is higher than the disease tendency judgment value, the tendency of the predetermined disease is estimated. When determining the likelihood of having a disease, it is possible to accurately determine the illness tendency for both people who are easily misoperated and those who are difficult to misoperate. In the initial state before it appears, the possibility of suffering from a predetermined disease can be known by a portable information processing device used daily. Thereby, the user can be detected at an early stage and can find out that he / she has a predetermined disease.

  According to the second aspect of the present invention, when the value of the erroneous operation frequency is higher than the disease tendency determination value, the predetermined disease tendency degree is determined according to the degree of deviation of the erroneous operation frequency value from the disease tendency determination value. Since the estimation is performed, the user can know the possibility of having a predetermined disease with a higher probability (the degree of progression of brain abnormality). In particular, there are cases where brain abnormalities have progressed considerably, such as when the interval between using portable information processing devices has been considerable, so the probability of having a given disease even in such cases If we can know, we can eliminate unnecessary anxiety of the user.

  According to the invention described in claim 3, when it is determined that the operation immediately before the operation location is operated is also the operation of the operation location for switching the screen information, the operation location is operated. If it is determined that the screen information after the switching is the same information as the screen information before the screen information is switched by the previous operation, it is determined to be an erroneous operation. Even when an erroneous operation occurs at an operation location where an instruction for switching is input, the erroneous operation can be reliably grasped.

  According to the fourth aspect of the present invention, when it is determined that the cancel key has been operated, it is determined that the operation is erroneous. Therefore, it is possible to easily and reliably grasp whether or not the operation is erroneous.

  According to the invention described in claim 5, since it is determined that the operation is erroneous when it is detected that the operation within the predetermined range from the operation location excluding the operation location is performed, the input is frequently performed regardless of the predetermined disease. It is possible to obtain information on the tendency of a predetermined disease with high reliability as compared with character input on a keyboard in which an error occurs.

  That is, in the case of keyboard character input, etc., an operation error not related to a disease is likely to occur because a very adjacent key is operated in a short period of time. However, an operation within a predetermined range is operated from an operation location excluding the operation location. In this case, since the operation is performed alone, operation mistakes unrelated to the disease are less likely to occur compared to character input on the keyboard. Thereby, it is possible to obtain information on a tendency of a predetermined disease with high reliability (disease related to brain abnormality).

  According to the invention described in claim 6, when the frequency of erroneous operation is higher than the disease tendency determination value, the disease tendency when the deviation degree between the error operation frequency value and the disease tendency determination value is a predetermined value or more. Since the test is performed (the disease tendency test is performed only when there is a high possibility of having a predetermined disease), the complexity of the test test is reduced as compared with the normal disease test.

  According to the seventh aspect of the present invention, as a disease tendency test, a display location where a predetermined order is displayed is displayed on the display means, and an instruction operation is performed in the order of the display locations displayed on the display means. Thus, since the disease tendency is determined according to the measurement time required to instruct and operate all the display locations, it is possible to obtain more accurate information on the probability of having the disease.

  According to the invention described in claim 8, since the data regarding the tendency of the disease is output to the external network means of the portable information processing apparatus with the disease tendency estimation function, the predetermined tendency of the disease is given to the medical institution or the like. It can be communicated quickly and the subsequent processing can be taken quickly.

  According to the invention described in claim 9, when it is determined that the user's use environment is not an environment suitable for using the information processing means with a disease tendency estimation function, the information processing means is used. Therefore, it is possible to obtain accurate information on whether or not the operation is an erroneous operation.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is an external view of a portable information processing apparatus with a disease tendency estimation function of the present invention. In this embodiment, a personal digital assistant (PDA) is used as a portable information processing apparatus with a disease tendency estimation function.

  The PDA 101 includes a touch panel 102, a home key 103, a cancel key 104, a scroll key 105, an OK key 106, and a menu key 107. The PDA 101 is operated using a touch pen 108 or the like.

  The touch panel 102 is a transparent panel that is arranged so as to overlap with a screen of a display unit (to be described later) that displays various screen information (display screens (windows) of various software). The user can view the screen information via the touch panel 102. The touch panel 102 also has a function of detecting which part of the touch panel 102 is touched by the user using the touch pen 108 or the like. For example, when the user operates an operation location (to be described later) for switching screen information via the touch panel 102, it is detected that the operation location has been operated. Recognition of which part on the touch panel 102 is touched is performed by position input information indicating which position on the operation surface such as coordinates and input key positions (not shown) on the touch panel 102 is touched.

  The home key 103 is a button for displaying a main screen on the touch panel 102 by a user operation. That is, even when the user is using certain software (different from the main screen) displayed on the touch panel 102, the home key 103 is operated to display the software on the touch panel 102. The main screen is displayed (switches to the main screen). Note that all software (such as dictionary software) installed in the PDA 101 is activated by selecting an icon from the main screen.

  Here, “displayed on the touch panel 102” means that the screen information displayed by the display means is displayed via the touch panel 102. From the viewpoint of the user, it is as if the screen information is displayed. Is used because it appears to be displayed on the touch panel 102.

  The cancel key 104 is used for canceling the selected item when the user selects a certain item displayed on the touch panel 102 by using the touch pen 108 or the like, and to return to the state before the selection. Button used. In short, it is a button operated to cancel (cancel) the operation performed immediately before.

  The scroll key 105 is a button used for moving a cursor displayed on the touch panel 102. When the upper part of the scroll key 105 is pressed, the cursor moves to the upper part. When the lower part is pressed, the cursor moves to the lower part. Similarly, when the left part is pressed, the cursor moves. Moves to the left, and the cursor moves to the right when the right is pressed.

  An OK key 106 is a button for determining selection. Specifically, when the user tries to select an item displayed on the touch panel 102, the cursor is moved to the position of the item that the user desires to select using the scroll key 105 described above. Then, after the cursor moves to the position of the item that the user desires to select, it is determined that the item has been selected by pressing this button.

  The menu key 107 is a button for displaying a menu list on the touch panel 102 when the software used by the user has a menu bar (a list of functions that can be used). When the user presses the menu key 107, the menu is displayed on the touch panel 102. This menu can also be displayed on the touch panel 102 by touching a menu bar (not shown) displayed on the touch panel 102 with the touch pen 108.

  A usage example of the above-described key (button) will be described.

  For example, when the user is browsing the contents of the received mail using the mail software of the PDA 101, it is assumed that a lexical or the like that does not understand the meaning of the contents of the received mail is found.

  Therefore, the user operates the home key 103 to display the main screen on the touch panel 102 in order to examine the meaning of the lexical word whose meaning is unknown. Since the dictionary software icon is displayed on the main screen, the user uses the scroll key 105 to move the cursor to the position of the dictionary software icon displayed on the main screen. After the cursor is moved, the dictionary key can be used by operating the OK key 106. After the dictionary software can be used, the user examines the meaning of the unknown lexical word using the dictionary software.

  Here, even if the user is using the dictionary software, the mail software has not ended, so after the user has examined the contents of the lexical words that the user does not understand using the dictionary software. The user can browse the contents of the received mail. In this case, the dictionary software is terminated and the mail software is used again.

  When the user wants to send a reply mail to the sender of the received mail, the user operates the menu key 107 to display a menu on the touch panel 102 and display the menu. When the cursor is moved to the reply mail item in the menu using the scroll key 105 and the cursor is moved, the reply mail window is opened by operating the OK key 106.

  Note that these operations can also be performed by pressing (operating) items displayed on the touch panel 102 using the touch pen 108 or the like.

  FIG. 3 is a diagram showing a window screen including an operation location displayed on the display screen of the portable information processing apparatus with a disease tendency estimation function.

  FIG. 3A shows a window A 401 displayed on the touch panel 102. In this window A401, an operation button 402a of a selection item 402 and an operation button 403a of a selection item 403, which are operation locations for inputting instructions for switching screen information, are displayed. The user can switch to a screen corresponding to the selection item 402 by operating the operation button 402a of the selection item 402 using the touch pen 108 or the like. Similarly, the user can switch to the screen corresponding to the selection item 403 by operating the operation button 403 a of the selection item 403.

  There is a possibility that the user touches the operation button 402a of the selection item 402 within a predetermined range (an area having a radius of about 5 mm) from the operation button 402a of the selection item 402 when the user tries to operate the operation button 402a of the selection item 402 using the touch pen 108 or the like. It is a high area. When a user tries to operate the operation button 402a of the selection item 402 by using the touch pen 108 or the like in a predetermined range from the operation button 402a of the selection item 402. This is an error operation area 404 that has a high possibility of being touched by mistake.

  Accordingly, a region obtained by adding the region of the operation button 402a and the error operation region 404 becomes a region within a predetermined range from the operation button 402a of the selection item 402.

  In FIG. 3A, the error operation area 404 of the operation button 402a of the selection item 402 has been described. However, the operation button 403a of the selection item 403 also has an error operation area (not shown) similar to the operation button 402a of the selection item 402. ).

  The error operation area of the operation button 403a of the selection item 403 is the same as the error operation area of the operation button 402a of the selection item 402, and the description thereof will be omitted.

  When the erroneous operation area 404 is pressed, it is determined that the user has erroneously operated the erroneous operation area 404 in an attempt to operate the operation button 402a of the selection item 402 (determined as an unintended operation). it can.

  In the PDA 101 of this embodiment, when the operation button 402a of the selection item 402 is operated, the screen is switched to a screen corresponding to the selection item 402, and when the operation button 403a of the selection item 403 is operated, the screen corresponding to the selection item 403 is displayed. Switch. Further, when the error operation area 404 is operated, the screen is not switched. When switching, it may change at the moment of operation, or a button such as [Next] is displayed at the corner of the window, and there is a case where switching does not occur unless the button is touched with the touch pen 108.

  In the present embodiment, it has been described that the screen is not switched when the error operation area 404 is operated. However, the present invention is not limited to this, and the screen may be switched to a screen (other screen) not intended by the user. Good.

  FIG. 3B shows a window B411 displayed on the touch panel 102.

  The window B411 includes a close button 412 on the upper right. When the user operates the close button 412 using the touch pen 108 or the like, the window B411 is closed (finished).

  A region within a predetermined range (region having a radius of about 5 mm) from the close button 412 is a region that is likely to be touched when the user tries to operate the close button 412 using the touch pen 108 or the like. The error operation area 413 is an area in which a user may accidentally touch when the user tries to operate the close button using the touch pen 108 or the like. That is, when the erroneous operation area 413 is operated, the operation is determined as an operation (incorrect operation) not intended by the user.

  FIG. 4 is a diagram showing a confirmation screen displayed on the touch panel 102.

  These confirmation screens are displayed on the touch panel 102 when an important operation (for example, an operation for closing a window or an operation when some setting is performed) is performed.

  In FIG. 4A, when “* * * OK? Are you sure?” Is displayed, if it is good, press the “Yes button 422” using the touch pen 108 or the like, and if not, Presses the “No button 423”. Here, when the user presses the “No button 423”, since the content instructed by the operation immediately before (one time before) is not performed, the operation immediately before (one time before) is not intended by the user. It can be determined that the operation (operation error). As this “* * *. Are you sure?”, For example, “Exit. Are you sure?”.

  Next, in FIG. 4B, when the message “Start setting XX” is displayed, if the user intends to set XX, the “Next button 432” is pressed. If there is no intention to set XX, the “return button 433” is pressed. Here, when the user presses the “return button 433”, the screen immediately before (once before) is returned to, so the operation immediately before (once before) is an operation (erroneous operation) unintended by the user. You can judge. Examples of the “start setting of ○○” include “start initial setting”.

  In general, a screen as shown in FIG. 3 or 4 is often used for an overview of software displayed on the PDA 101. An object of the present invention is to grasp a disease tendency by counting the frequency when the error operation area 404 and error operation area 413 in FIG. 3 and the return button 433 in FIG. 4 are operated.

  FIG. 5 is a diagram showing a display screen when a TMT test is performed using the PDA 101. This test is performed when there is a high possibility that the user's brain is abnormal as will be described later. In the window E701 displayed on the touch panel 102, numbers 1 to 20 are randomly arranged on the screen, and “trace the numbers 1 to 20 in order” below the screen. The explanation is made.

  In the TMT test, the user traces numbers from 1 in order, but when the user presses the number 1 with the touch pen 108 or the like, the measurement timer starts from that time and the required time is measured. Is started. When the number from 1 to 20 is traced, the measurement timer is stopped and the measurement of the required time is completed.

  After the TMT test is completed, the possibility of brain abnormality (disease tendency estimation value) is determined by the determination unit 207 as described later.

  Although details of the possibility of this brain abnormality will be described later, the degree of divergence with respect to a value obtained by multiplying the average value of the frequency of erroneous operations in the past by a constant and the required time measured by the TMT test are used as judgment factors. The determination is made by applying to a disease tendency determination table (not shown) prepared in advance.

  After the determination, the display means 203 displays the determined possibility of abnormal brain. Thereby, the user can know the possibility of abnormality of the brain displayed on the touch panel 102.

  In the present invention, TMT is given as an example, but various tests are conceivable depending on the disease suspected of the user, and it is not necessary to use TMT. It is preferable to perform a test according to the situation.

  As an indication of the degree of abnormalities in the brain displayed on the touch panel 102, for example, when the progression of abnormalities in the brain is considered to be low (possibility), “the possibility that there is an abnormality in the brain is detected a little. If possible, please go to the hospital for an examination. Also, if there is a possibility that the progression of brain abnormalities is progressing a little, “There may be an abnormality in the brain. Be sure to go to the hospital for an examination. Estimated brain disease 50%” If there is a possibility that the progress of abnormalities of the brain is progressing, "There is a high possibility that there is an abnormality in the brain. Please go to the hospital early and test. Estimated brain disease 80% Is displayed.

  Here, the estimated value of brain disease is determined in advance by using the degree of deviation from the average value of the frequency of erroneous operations in the past and the value obtained by multiplying the constant by the constant and the required time measured by the TMT test in advance. It is determined by a prepared disease tendency determination table (not shown).

  In addition, the display of this display means 203 is an illustration, Comprising: The display method is not limited to the said content. Further, the display contents displayed on the display means 203 may be described on the display screen of the PDA 101 or the instruction manual as an explanation for facilitating understanding of the contents.

  In the above description, the possibility of a brain abnormality is determined by the determination unit 207, and the determination result is displayed on the touch panel 102. However, the determination result is not limited thereto, and the determination result is transmitted from the transmission unit 210 to the outside. It may be transmitted to a medical institution through the network. As a result, it is possible to quickly transmit the data for determining the possibility of a brain abnormality to a medical institution, etc., and the medical institution etc. will reply to the action to be taken in the future depending on the possibility of the brain abnormality. It is possible to take early treatment without progression of brain abnormalities.

  FIG. 6 is a flowchart for explaining the disease tendency estimation processing.

  First, in step (hereinafter referred to as “S”) 1, it is determined whether or not a user input flag is ON. This user input flag is used to determine whether or not information for identifying the user of the PDA 101 has already been input. The user input flag is turned ON by S3 described later and turned OFF by S9.

  If it is determined in S1 that the user input flag is not ON, it is determined in S2 whether or not information specifying the user such as the user (user) name, age, and sex is input. Specifically, the information for specifying the user is input by inputting it in the name input field, age input field, and gender selection field on the user specifying input screen (not shown) displayed on the touch panel 102. When the input to all the input fields is completed, the user operates the user information input completion button (not shown) to input information for identifying the user. As a result, the user of the PDA 101 is confirmed.

  If it is determined in S2 that the information for identifying the user has not been input, the process proceeds to S8. If it is determined that the information has been input, the user input flag is set to ON in S3. In step S4, information for identifying the user is recognized and stored. Information for identifying the user is stored in the storage hand 209.

  By setting the user input flag to ON by S3, YES is determined by S1 in the next disease tendency estimation process, and the user specified above is the user of PDA1 unless the user of PDA101 is changed. Identified as

  On the other hand, if it is determined in S1 that the user input flag is ON, it is determined in S5 whether or not an input for changing the user (user) is made. Specifically, the input for changing the user is the name input field, the age input field, and the gender selection field of the user change input screen (not shown) displayed on the touch panel 102. Entering information such as age, gender, etc. When all the input fields have been entered, operating the user change input button (not shown) will input information that identifies the user to be changed Is done. Thereby, the user of the changed PDA 1 is specified.

  If it is determined in S5 that the information for specifying the user for changing the user has not been input, the process proceeds to S6. If it is determined that the information has been input, the user is specified in S4. Recognize and store information. Thus, the changed user can be recognized, and the changed user is specified as the user of the PDA 101 in the future.

  In S6, touch panel input disease tendency processing is performed. As will be described later with reference to FIG. 7, the touch panel input disease tendency process is performed to determine the frequency of an erroneous operation (erroneous operation) of the user when an input operation is performed by the user using the touch pen 108. It is calculated and the possibility (disease tendency) that the user has a disease (brain abnormality) is determined from the frequency of the erroneous operation.

  Next, in S7, key input disease tendency processing is performed. As will be described later with reference to FIG. 8, the key input disease tendency process is performed by calculating the frequency of user's erroneous operation obtained from the operation of the cancel key 104 when the user operates the cancel key 104. It is calculated and the possibility (disease tendency) that the user has a disease (brain abnormality) is determined from the frequency of the erroneous operation.

  In S8, it is determined whether or not the user has finished using the PDA 101. Specifically, the use of the PDA 101 is ended when the user operates an end button (not shown) displayed on the touch panel 102. If it is determined in S8 that the use of the PDA 101 has ended, the user input flag is turned OFF in S9, and the disease tendency estimation process ends.

  In this embodiment, the use of the PDA 101 is terminated by operating an end button displayed on the touch panel 102. However, the present invention is not limited to this, and an end key (home key 103) that can be recognized from the outside is not limited thereto. Or a button such as a cancel key 104), and the end key may be operated to end the operation.

  In the present invention, the user information is input in detail. However, the user may be identified only by inputting the user name. In the first place, from the viewpoint that the PDA 101 is used by an individual (only one PDA 101 is used), user input is not necessarily required.

  FIG. 7 is a flowchart for explaining touch panel input disease tendency processing.

  First, in S21, touch panel operation detection processing is performed. In this touch panel operation detection process, as will be described later with reference to FIG. 9, a predetermined operation is performed by a user from a desired operation location (the operation button 402 a of the selection item 402, the operation button 403 a of the selection item 403, the close button 412, etc.). It is detected whether or not an operation within a range (a range including a desired operation location, an error operation area 404, and an error operation area 413) has been performed. Here, the desired operation location is a portion that the user considers to press in the software currently being used by the user. Since the user may wish to select the selection item 403, simply selecting one of the operation button 402 or the selection item 403 does not immediately determine an error.

  In S22, it is determined whether or not the operation flag is ON. If it is determined that the operation flag is not ON, the process proceeds to S23a. If it is determined that the operation flag is ON, the process proceeds to S23. This operation flag is turned ON by S56 in FIG. That is, the user uses a touch pen 108 or the like to move from a desired operation location (the operation button 402a of the selection item 402, the operation button 403a of the selection item 403, the close button 412) to a predetermined range (a desired operation location, an error operation). When it is determined that the area 404 (range including the error operation area 413) has been operated, it is turned ON. This operation flag is turned OFF by S32 described later.

  In S23, a cancel operation determination process is performed. In this cancel operation determination process, it is determined whether or not the user touches a predetermined position on the touch panel 102 using the touch pen 108 or the like, and the operation is an operation (incorrect operation) not intended by the user. .

  In S <b> 23 a, the time when the touch panel 102 touches a predetermined position using the touch pen 108 or the like by the user, the operation content (for example, the type of window, the operated location, etc.) are stored in the storage unit 209. Is done. That is, in this storage means 209, not only the operation of the desired operation location (the operation buttons of the selection items 402 and 403, the close button 412) but also a predetermined range (error operation area 404, error operation area) from the desired operation location. 413), and other touch panel 102 operations are stored.

  Then, in S24, it is determined whether or not the cancel flag is ON. This cancel flag is turned ON in S66 of FIG. If it is determined in S24 that the cancel flag is not ON, the process proceeds to S26, and if it is determined that the cancel flag is ON, the process proceeds to S25.

  In S25, the operation time of the operation determined to be an erroneous operation, the operation content (for example, the type of window, the operated location, etc.), etc. are stored in the storage means 209. Here, the operation determined to be an erroneous operation refers to an operation when the cancel flag is turned ON by the cancel operation determination process in S23. That is, the storage means 209 stores the operation content determined as an erroneous operation among the operations of the desired operation location (the operation buttons of the selection items 402 and 403, the close button 412), the error operation area 404 shown in FIG. The operation content within the area 413 is stored.

  The PDA 101 is used when the PDA 101 is operated in a dim environment or an environment in which shaking is intense and the user cannot press the operation location accurately (for example, when using the PDA 101 while driving a car). If the environment is not suitable for using the PDA 101, the storage means 209 does not have to store the time when the erroneous operation was performed and the content of the operation in S25. Judgment whether or not the usage environment of the PDA 101 is suitable for using the PDA 101 includes, for example, an acceleration sensor, a vibration sensor, a magnetic sensor, an illumination sensor, etc. provided in the PDA 101, the acceleration sensor, Depends on whether the acceleration, vibration, brightness, etc. measured by vibration sensors, lighting sensors, etc. are greater than or equal to a predetermined acceleration, and whether or not they are greater than or equal to a predetermined vibration. This is done depending on whether the brightness is below. As described above, if the usage environment of the PDA 101 is not suitable for using the PDA 101, the time when the erroneous operation is performed, the content of the operation, and the like are not stored in the storage unit 209 in S25. You can get accurate information about.

  These erroneous operation detection methods are characterized in that they are performed from among software operations that are casually used by the user. The casually used software is frequently used and does not require particularly sophisticated input / output. For example, e-mail software or an Internet browser are optimal.

  In S26, an erroneous operation frequency calculation process is performed. This erroneous operation frequency calculation processing will be described later with reference to FIG. 12, but the frequency of operations that are determined to be erroneous operations among operations performed by the user using a touch pen or the like is calculated. The frequency of this erroneous operation is obtained from the number of erroneous operations performed within a predetermined time (for example, 5 minutes).

  In S27, it is determined whether or not the frequency of erroneous operations has been calculated. If it is determined that the frequency has not been calculated, the process proceeds to S32. If it is determined that the frequency has been calculated, the past erroneous operation frequency calculation process is performed in S28. Is done.

  Whether or not the frequency of the erroneous operation has been calculated is determined as the frequency of the erroneous operation is stored in S91 of FIG. 12 to be described later, and when the timer flag is turned off in S92. .

  In S28, a past erroneous operation frequency calculation process is performed. This past erroneous operation frequency calculation process will be described later with reference to FIG. 13, but an average value of past erroneous operation frequency values is calculated. The average value of the frequency of past erroneous operations is determined for each user, and is obtained from data on the frequency of past erroneous operations of the user stored in the storage unit 209.

  In addition, when there is no data on the frequency of past erroneous operations of the user in the storage unit 209, a value prepared in advance is used.

  In S29, the value of the erroneous operation frequency calculated in S26 is compared with the value (disease tendency determination value) obtained by multiplying the average value of the past erroneous operation frequency values calculated in S28 by the constant K, and in S26. It is determined whether or not the calculated erroneous operation frequency value is greater than a value obtained by multiplying the average value of past erroneous operation frequency values calculated in S28 by a constant K, and the erroneous operation frequency calculated in S26. If it is determined that the value is smaller than a value obtained by multiplying the average value of the frequency of past erroneous operations calculated in S28 by a predetermined number K, the process proceeds to S32, and if it is determined that the value is larger, the process proceeds to S30. Thus, a disease tendency test process is performed.

  In this way, by comparing with the individual disease tendency judgment values, when determining the possibility of brain abnormalities (disease tendency), the disease tendency for both people who are easy to misoperate and those who are difficult to misoperate Can be determined accurately.

  In S30, a disease tendency test process is performed. This disease tendency test process is a process in which a TMT test (see FIG. 5) is performed using the PDA 101. Specifically, when this disease tendency test process is performed, a window E701 shown in FIG. Then, the user traces the numbers displayed in this window E701 in the order of numbers from 1 to 20, and measures the required time. The measurement time measured by the disease tendency test process is used when determining the possibility of brain abnormality.

  As described above, when it is determined in S29 that the value of the frequency of erroneous operations is larger than the disease tendency determination value, the disease tendency test process is further performed, so that more accurate information on the probability of having the disease is obtained. Can be obtained.

  It should be noted that the disease tendency test process in S30 is performed when the value of the erroneous operation frequency is greater than the disease tendency determination value and the degree of deviation between the erroneous operation frequency value and the disease tendency determination value is equal to or greater than a predetermined value. Only testing may be performed. As described above, since the disease tendency test is performed only when there is a high possibility of having a predetermined disease, the complexity of the test inspection is reduced as compared with the normal disease inspection.

  Next, by S31, the deviation degree indicating how much the value of the frequency of erroneous operations deviates from the disease tendency judgment value, the measurement time measured in the TMT test performed by the disease tendency test process, and the dissociation degree The touch panel 102 displays a disease tendency estimation value indicating the possibility that the user who has been determined using a disease tendency determination table prepared in advance has a disease (brain abnormality) using the time counted as a determination factor. Is displayed.

  For example, when the divergence degree and the measurement time are used as determination factors, the disease tendency determination table is divided into five stages for the divergence degree, and the measurement time is also divided into five stages. The measurement period is assigned to a matrix table of 5 levels, and the possibility of brain abnormality is determined. If only the degree of divergence or measurement time is used as the decision factor, it is similarly applied to the table of divergence degree divided into five stages and the table of measurement time divided into five stages. Determine the possibility of abnormalities.

  Thus, since the possibility of the brain abnormality (the tendency of the disease) is estimated according to the deviation of the frequency of the erroneous operation from the disease tendency judgment value, the user can determine the possibility of having the disease. It is possible to know with higher probability (the degree of progression of brain abnormalities).

  Instead of displaying on the touch panel 102, the display may be displayed on the touch panel 102, and the above contents may be conveyed to the user by voice using voice output means (not shown).

  By using the software interface (windows, buttons, etc.) during the operation of software that routinely uses the above routines, brain abnormalities can be detected in the initial state before changes in physical condition occur. The user can know the possibility (disease tendency) of the disease, and can detect at an early stage that he / she is inspected at a hospital and suffers from a predetermined disease.

  Further, as the result output of S31, in this embodiment, the degree of deviation indicating how far the disease tendency judgment value has deviated, the measurement time measured in the TMT test performed by the disease tendency test process, and the like are displayed on the touch panel 102. Although the method of displaying above and the method of outputting by audio output means have been described, the present invention is not limited to this, and the transmission means 210 may transmit the data to a medical institution or the like via a network.

  Thereby, a medical institution or the like can determine the possibility of a brain abnormality (trend of disease) using the degree of deviation or measurement time transmitted by the transmission unit 210 as a determination factor, and the medical institution Future treatments and the like for the brain abnormality are transmitted to the PDA 101, and the user can take appropriate treatments at an early stage.

  Further, the storage means 209 stores the degree of deviation indicating how much the frequency of erroneous operations deviates from the disease tendency judgment value, the measurement time measured in the TMT test performed by the disease tendency test process, and the like. It may only be done. In this case, the user will bring the data stored in the storage unit 209 to the medical institution at a later date, and the data stored in the storage unit 209 will be analyzed by a doctor of the medical institution or the like. Thus, a doctor of a medical institution or the like can know the state of the user at a specific time in the past.

  Next, in S32, the operation flag and the cancel flag are turned OFF. Thereby, a touch panel input disease tendency process is complete | finished. This is terminated at the same time when the user terminates the software.

  FIG. 8 is a flowchart for explaining key input disease tendency processing.

  First, in S41, a cancel key determination process is performed. In this cancel key determination process, which will be described later with reference to FIG. 11, it is determined whether or not the cancel key 104 has been pressed (operated) by the user.

  Next, in S42, it is determined whether or not the cancel key flag is ON. If it is determined that the cancel key flag is not ON, the process proceeds to S44, and it is determined that the cancel key flag is ON. In S43, the operation time of the cancel key 104, the operation time of the user's operation immediately before the cancel key 104 is operated (one time before), the operation content (window screen, operation location, etc.), etc. Is stored in the storage means 209.

  As described above, when a user selects a certain item displayed on the touch panel 102, the cancel key 104 is a button used to cancel the selection and return to the state before the selection. is there. From this, it can be determined that the operation immediately before (one time before) the cancel key 104 is operated is an erroneous operation.

  As in the touch panel input illness tendency process described above, when it is determined that the usage environment of the PDA 101 is not suitable for using the PDA 101, such as when the PDA 101 is being used while driving a car, S43 , The time when the erroneous operation was performed, the content of the operation, and the like may not be stored in the storage unit 209.

  In S44, an erroneous operation frequency calculation process is performed. The erroneous operation frequency calculation process is the same as the erroneous operation frequency calculation process described in S26 of FIG.

  In S45, it is determined whether or not the frequency of erroneous operations has been calculated. If it has not been calculated, the process proceeds to S50, and if it has been calculated, the process proceeds to S46.

  Note that the frequency of this erroneous operation is calculated in S90 of FIG. 12, which will be described later, similarly to the processing of S26 of FIG.

  In S46, past erroneous operation frequency calculation processing is performed. Since this past erroneous operation frequency calculation process is the same process as S28 of FIG. 7, description thereof is omitted.

  In S47, it is determined whether or not the value of the erroneous operation frequency calculated in S44 is larger than a value (disease tendency determination value) obtained by multiplying the average value of the past erroneous operation frequency values by a predetermined number N. If it is determined, the process proceeds to S50, and if it is determined to be large, the process proceeds to S48. The process of S47 is a process corresponding to S29 of FIG.

  The K (constant) used in the disease tendency determination value of the touch panel input disease tendency process is different from the constant N used in the disease tendency determination value of the key input disease tendency process. It is good also as the same value.

  In S48, a disease tendency test process is performed. Since this disease tendency test process is the same process as the disease tendency test process of S30, description thereof is omitted.

  Next, a result output process is performed by S49. Since this result output is the same process as the result output process of S31, the description is omitted.

  Then, in S50, the cancel key flag is turned off, and the key input disease tendency process is ended.

  FIG. 9 is a flowchart for explaining the touch panel operation detection process. This touch panel operation detection process is performed in S21 of FIG.

  First, in S55, a predetermined range (desired operation location, error operation area 404) from an operation location desired by the user (for example, the operation button 402a of the selection item 402, the operation button 403a of the selection item 403, the close button 412, etc.). It is determined whether or not the operation within the error operation area 413 has been performed. Specifically, using the touch pen 108 or the like, whether a predetermined range (the range of the operation button 402 or 403 or the error operation area 404) is operated from the operation button 402 or 403 of the selection item shown in FIG. It is determined whether or not a predetermined range (the range of the close button 412 and the error operation area 413) has been operated from the close button 412.

  If it is determined in S55 that the predetermined range from the desired operation location has not been operated, the touch panel operation detection process is terminated. If it is determined that the operation has been performed, the operation flag is turned ON in S56. .

  FIG. 10 is a flowchart for explaining the cancel operation determination process. This cancel operation determination process is performed in S23 of FIG.

  First, in S61, it is determined whether or not the user has operated a peripheral portion (such as the error operation areas 404 and 413) of a desired operation location. The peripheral portion of the desired operation location is a portion excluding the operation button 402a in the predetermined range (operation button 402a, error operation area 404) in the selection item 402 in FIG. Further, the close button 412 in FIG. 3B is a portion excluding the close button 412 within the predetermined range (the close button 412 and the error operation area 413). The peripheral portion of the desired operation portion is a portion where the user is likely to operate erroneously in an attempt to select the selection item 402 or 403 and the close button 412.

  If it is determined in S61 that the user has operated the peripheral portion of the desired operation location, the process proceeds to S66, and if it is determined that the user has not operated, the process proceeds to S62.

  Since the periphery of the desired operation location is a portion that is highly likely to be erroneously operated by the user, the user operation at this desired operation location is intended to operate the operation location desired by the user. It can be determined that the operation is incorrect (erroneous operation).

  In S62, it is determined whether or not the screen has been switched. That is, it is determined whether or not a portion other than the peripheral portion of the desired operation portion is operated in S61 and the screen displayed on the touch panel 102 is switched by the operation. If it is determined in S62 that the screen has not been switched, the cancel operation determination process is terminated. If it is determined that the screen has been switched, information on the screen before the screen is switched is stored. Here, the screen information before switching is information for specifying the screen before switching, and stores, for example, the URL, identifier, etc. of the screen information.

  The determination as to whether or not the screen has been switched is made based on whether or not the frontmost screen has been switched when two or more screens (software) are displayed on the touch panel 102.

  In S64, it is determined whether or not the operation immediately before the switching operation in which the screen is switched in S62 is also an operation for switching the screen, and it is determined that the operation immediately before the screen switching operation is also the screen switching operation. If YES in step S65, the process advances to step S65. If it is not determined that the screen switching operation has been performed, the cancel operation determination process ends.

  In S65, information (for example, URL, identifier, etc.) specifying the screen after the screen switching and information (for example, URL, identifier, etc.) specifying the screen before the switching operation of the previous switching operation is specified. Are determined to be the same, the process proceeds to S66 if determined to be the same, and the cancel operation determination process is ended if determined to be not the same.

  Next, in S66, the cancel flag is turned ON. This cancel flag is a flag that is turned ON when it is determined that the operation determined in FIG. 10 is a cancel operation. When this cancel flag is turned on, a YES determination is made in S24 of FIG.

  The cancel operation determination process has been described above. To explain it a little more easily, first, the screen displayed on the touch panel 102 starts from the state where the screen A is displayed. It is assumed that the screen is changed to the screen B by operating the operation portion desired by the user in the state of the screen A. When the screen is switched from the screen A to the screen B due to an incorrect operation by the user, the user returns the switched screen (screen B) to the original screen (screen A) once, It is assumed that the user will perform the operation intended again. The basic principle of the cancel operation determination process in FIG. 10 is to determine whether or not an erroneous operation has been performed by the user by determining whether or not these operations have been performed.

  When this operation is applied to the cancel operation determination process of FIG. 10, first, it is assumed that the screen displayed on the touch panel 102 is the screen A. Then, it is assumed that the screen is switched from the screen A to the screen B by operating other than the peripheral portion of the desired operation location in S61. In this case, YES is determined in S62, and information on the screen A before switching is stored in S63. Next, when it is determined in S64 that the previous operation is not a switching operation, the cancel operation determination process ends. When the next cancel operation determination process is performed, the screen displayed on the touch panel 102 is the screen B. In the state of this screen B, when it is determined in S61 that the operation on the screen B is an erroneous operation, in order to return the screen B to the screen before the erroneous operation (screen A), the user can The screen is switched from the screen B to the screen A (YES in S62). Next, the information of the screen B before the screen switching is stored, and the information of the screen A after the switching is stored. Then, it is determined whether or not the information before switching of the switching operation one time before the switching operation (information on screen A) is the same, and since both are screen A, it is determined YES in S65, It is determined that the operation of returning from screen B to screen A is an operation for canceling screen B, and the switching operation from screen A to screen B is determined to be an erroneous operation.

  As described above, when it is determined that the operation immediately before the desired operation location is operated is also the operation of the desired operation location for switching screen information, the desired operation location is operated. When it is determined that the screen information after switching and the screen information before the screen information is switched by the previous operation are the same information, it is determined to be an erroneous operation. Therefore, even when an erroneous operation at a desired operation location for inputting an instruction is performed, the erroneous operation can be reliably grasped.

  FIG. 11 is a flowchart for explaining cancel key determination processing. This cancel key determination process is performed in S41 of FIG.

  First, in S71, it is determined whether or not the cancel key 104 has been pressed (operated) by the user.

  As described above, the cancel key 104 is used to cancel the selection after an item on the touch panel 102 is selected. The cancel key 104 is used to return to the operation performed immediately before (cancel). Therefore, it can be determined that the operation performed immediately before (one time before) was an erroneous operation by the user.

  If it is determined in S71 that the cancel key 104 has not been pressed (operated), the cancel key determination process is terminated. If it is determined that the cancel key 104 has been pressed, the cancel key flag is turned ON in S72. When this cancel flag is turned on, a YES determination is made in S42 in FIG.

  In the present embodiment, an example of performing a cancel operation using the cancel key 104 provided outside the PDA 101 has been described. However, the present invention is not limited to this, and a cancel button displayed on the touch panel 102 or the like. Even when (see FIG. 4) is operated, the same processing as in FIG. 11 is performed.

  FIG. 12 is a flowchart for explaining an erroneous operation frequency calculation process. This erroneous operation frequency determination process is performed in S26 of FIG. 7 and S44 of FIG. In this erroneous operation frequency calculation process, the number of erroneous operations of the user within a predetermined period (the timer time of the erroneous operation frequency calculation timer, for example, 5 minutes) is calculated, and the number of erroneous operations is used as the frequency of erroneous operations.

  First, in S81, it is determined whether or not the timer flag is ON. If it is determined that the timer flag is ON, the process proceeds to S84, and if it is determined that the timer flag is not ON, the process proceeds to S82. This timer flag is turned ON when the frequency of erroneous operations is calculated, and is turned OFF when the calculation of the frequency of erroneous operations is completed.

  In S82, an erroneous operation frequency calculation timer is started, and in S83, the timer flag is turned ON. Thereby, an erroneous operation frequency is calculated.

  In S84, it is determined whether or not the erroneous operation frequency calculation timer has expired. If it is determined that the time has not expired, the erroneous operation frequency calculation process is terminated. If it is determined that the time has expired, the process proceeds to S85. move on. As a result, the number of erroneous operations is calculated until the erroneous operation frequency calculation timer expires.

  In S85, the operation is classified for each operation key. Specifically, first, the operation for each window shown in FIGS. 3 and 4 is classified, and then the operation button for each window is classified.

  As a result, the frequency of erroneous operations for each operation button can be calculated. Further, this division may be made for each group determined in advance according to the ease of erroneous operation. As a result, even operation buttons that are less frequently used have sufficient data to determine a disease tendency, and a more accurate disease tendency can be determined.

  In S86, the non-operation time is calculated. This non-operation time corresponds to the instruction input by the user such as the time when the user is viewing the display screen displayed on the touch panel 102 of the PDA 101 or the time when the PDA 101 is not used due to a break or the like. This is calculated when the time (for example, 1 minute or more) is not performed. In order to calculate this non-operation time, in this embodiment, the time when the touch panel 102 was operated by the user is memorize | stored by S23a. The non-operation time of the user is calculated from the stored user operation time.

  As a result, the time when the user has not used the PDA 101 (including the browsing time) is removed, the operation time during which the user has used the PDA 101 is calculated, and a more accurate erroneous operation frequency can be calculated. .

  In this embodiment, the time when the user is not operating the PDA 101 is calculated as the non-operation time. However, when it is determined that the environment is not suitable for using the PDA 101 as described above, the determination is made. The calculated period may also be calculated as a non-operation period by S86.

  In S87, it is determined whether or not the non-operation time is calculated. If it is determined that the non-operation time is not calculated, the process proceeds to S89. If it is determined that the non-operation time is calculated, the operation frequency calculation timer is determined in S88. The calculated non-operation time is added.

  In this embodiment, a method of calculating the non-operation time and adding the non-operation time to the erroneous operation frequency calculation timer is used. However, the present invention is not limited thereto, and the non-operation time may not be added. According to this method, the number of erroneous operations is calculated per fixed time.

  In S89, the number of erroneous operations per predetermined period of the user is read out. The number of erroneous operations is read from the operation contents of the erroneous operations stored in the storage unit 209 by S25 in FIG. 7 and by S43 in FIG. Specifically, the number of erroneous operations divided for each software launched by the user is read.

  In S90, the frequency of erroneous operations is calculated. The frequency of this erroneous operation is calculated for each operation button of the divided software. Then, the total erroneous operation frequency for each software considering the frequency of all erroneous operations is calculated from the frequency of erroneous operations calculated for each operation button of the software. The total erroneous operation frequency is, for example, the frequency of erroneous operations calculated for each of the software operation buttons (the operation button 402a of the selection item 402, the operation button 403a of the selection item 403, and the close button 412) is X, Y, and Z, respectively. Then, the frequency X, Y, Z of the erroneous operation is multiplied by a predetermined coefficient (a, b, c), and the following (Expression 1) is obtained.

Total erroneous operation frequency = a * X + b * Y + c * Z (Formula 1)
Is required.

  Here, the constants (a, b, c) and the like are determined values in consideration of, for example, the possibility of pressing the operation button near the position, the size of the operation button, the usage frequency, and the like. is there.

  As described above, it is desirable to calculate the “total error operation frequency” for each software. For example, when using a web browser, the user frequently jumps to various homepages, and therefore, it is predicted that erroneous operations using the touch panel are increased as compared with others. On the other hand, the mail software is mainly browsed and filled in, and it is predicted that erroneous operations using the touch panel are less than those of the web browser. In this way, the usage is different depending on the software, so it cannot be calculated uniformly. Also, when playing a game or the like, the input frequency increases, so it is difficult to think of it as an index software for determining a brain disease, so it is desirable to exclude it from the target for calculating the frequency of erroneous operations.

  In the present embodiment, the frequency of erroneous operation is calculated for each operation button for each software, and the total erroneous operation frequency for each software is calculated from the calculated frequency of erroneous operations. May be divided into groups, the frequency of erroneous operations for each of the divided groups may be calculated, and the total erroneous operation frequency may be calculated from the calculated frequency of erroneous operations.

  In S91, the frequency of the erroneous operation calculated in S90 and the value of the total erroneous operation frequency are stored. The stored erroneous operation frequency and total erroneous operation frequency values are used when calculating an average value of past erroneous operation frequency values to be described later.

  Note that the frequency of erroneous operations and the frequency of total erroneous operations are stored in S90. However, the present invention is not limited to this, and when the frequency of past erroneous operations to be described later is obtained only from the frequency of erroneous operations, only the frequency of erroneous operations may be stored. When obtaining only from the total erroneous operation frequency, only the total erroneous operation frequency may be stored. In this case, if the stored content is the frequency of erroneous operations, the disease tendency is estimated from the frequency of erroneous operations. If the stored content is the total erroneous operation frequency, the disease tendency is calculated from the total erroneous operation frequency. Will be estimated.

  Next, in S92, the timer flag is turned off. When this timer flag is turned off, the frequency of erroneous operation for one time is calculated.

  FIG. 13 is a flowchart for explaining past erroneous operation frequency calculation processing. This past erroneous operation frequency calculation processing is performed by S28 of FIG. 7 and S46 of FIG.

  First, in S101, the value of the frequency of past erroneous operations is read. The past erroneous operation frequency value is read from the erroneous operation frequency value stored in S91 of FIG. The value of the frequency of past erroneous operations is calculated from all data calculated in the past for the current user.

  Next, in S102, an average value of past erroneous operation frequency values is calculated. The average value of the past erroneous operation frequency values is obtained by (a value obtained by adding all past erroneous operation frequencies / the number of past erroneous operation frequency values).

  FIG. 14 is a diagram showing a screen on which a window A401 is displayed on the touch panel. This window A401 is the same as the window A401 described with reference to FIG. In a normal use state, this window A401 is displayed on the touch panel 102 in the size shown in FIG.

  FIG. 14B shows a screen when the window A102 is enlarged. As a case where the window A401 is enlarged, for example, when the disease tendency estimation process is performed, the number of erroneous operations of the user becomes equal to or larger than a predetermined number.

  As a result, the user can easily operate by increasing the display of the window A401, and the number of erroneous operations can be reduced.

  The enlargement of the window A401 may be performed after S89 of the erroneous operation frequency calculation process. Since the enlargement of the window A401 and the like is performed for each software, the number of erroneous operations in S89 is obtained for each software as a premise.

FIG. 15 is an example of a time chart showing the total erroneous operation frequency per hour. In this time chart, the total erroneous operation frequency is expressed by (Equation 1).
X: Cancel processing on the touch panel (the number of times Y is set to S55 in FIG. 9 in 5 minutes)
Y: Cancel processing on the touch panel (number of times Y in S65 in FIG. 10 for 5 minutes)
Z: Cancel key determination process (the number of times Y in S71 of FIG. 11 in 5 minutes)
And a = 1, b = 1, and c = 0.5. The reason why c is weighted as 0.5 is that it is considered that the user presses the cancel key 104 during the actual operation by mistake, so that the user presses the cancel key 104 once every two times. For example, if the frequency of the erroneous operation is 5 minutes calculated by the erroneous operation frequency calculation timer in FIG. 12, and X is performed twice and Z is operated once in 5 minutes, the unit time shown in FIG. The total mistaken operation frequency is (1 * 2 + 1 * 0 + 0.5 * 1) / (5/60) = 30 (times / hour).

  The time axis on the horizontal axis displays a predetermined time (5 minutes in this case) measured by the erroneous operation frequency calculation timer in FIG. 15 as one unit, and the vertical axis indicates the frequency of erroneous operations.

  Here, 504 and 505 indicate the types of software, respectively. In this embodiment, as an example, 504 is a web browser and 505 is mail software.

  First, on the leftmost side, neither the web browser nor the mail software is activated, and then the user starts up the web browser (504a). After closing the web browser for a while, the user launched the mail software (505a). Web browsers often have many input items, and often return to the back while browsing. On the other hand, since the mail software is about the wrong input at the time of creating the mail, the total erroneous operation frequency is less than that of the web browser. The user has started the mail software again after a while after ending the mail software (505b). At this time, the value of the graph is 0 because the user did not operate items that affect the total erroneous operation frequency. The user lowered the mail software again, and the user started up the web browser again (504b), and then lowered the web browser and then started the mail software again (505c).

  An average value 501 of past erroneous operation frequency values is an average value of the total erroneous operation frequency during past web browser operations of the user. An average value 502 of past erroneous operation frequencies is an average value of the total erroneous operation frequency during the mail software operation. Further, the disease tendency determination value 503 is a threshold value obtained by multiplying the average value of the total erroneous operation frequency during the mail software operation by a constant (equivalent to the constant K of S29, the constant N of S47, for example, 3 times). , If the total frequency of erroneous operations during email software operations is greater than 503, it is determined that there is a high possibility of having an abnormal brain disease (for example, a transient ischemic attack or cerebral infarction) Or start a TMT test.

  In FIG. 15, for easy explanation, the total erroneous operation frequency 504 when operating the web browser and the total erroneous operation frequency 505 when operating the mail software are not overlapped on the time chart of FIG. In addition, there are cases where both of them stand up in the same time. For example, if the homepage address is entered in the email text, the user may launch a web browser while launching the email software. In this case, the mail software is hidden by the web browser and cannot be seen on the screen, or is partially hidden under the web browser. In this case, it is considered that the web browser is being operated instead of the mail software being operated, and the total erroneous operation frequency to be calculated is that of the web browser. That is, 504 is assumed.

  In order to facilitate the explanation, the average value of the frequency of past erroneous operations is set to a value as shown in FIG.

Below, the modification of this embodiment is demonstrated.
(1) In the erroneous operation frequency calculation processing of this embodiment, the number of erroneous operations per predetermined time counted by the erroneous operation frequency calculation timer excluding the non-operation time is obtained, and the erroneous operation frequency is calculated from the number of erroneous operations. However, the present invention is not limited to this. For example, the number of erroneous operations within a predetermined time (constant period) counted by an erroneous operation frequency timer is obtained, and the number of erroneous operations is divided by the total number of operations (number of erroneous operations / total operations). Frequency), the frequency of erroneous operations may be calculated.

Note that the number of erroneous operations may be obtained for each operation button as described in the present embodiment, or may be obtained by grouping according to the frequency of erroneous operations.
(2) In the present embodiment, in the cancel operation determination process of the touch panel input disease tendency process, it is determined as an erroneous operation when YES is determined in S61 and when an operation of proceeding from S62 → S63 → S64 → S65 is performed. However, the present invention is not limited to this, and in the cancel operation determination process of the touch panel input disease tendency process, it is determined as an erroneous operation only when YES is determined in S61, and S62 → S63 → S64 is determined by the cancel key determination process of the key input disease tendency process. → A case where the operation of proceeding to S65 is performed may be determined as an erroneous operation.

By determining in this way, in the touch panel input disease tendency process, it is determined as an erroneous operation that the user has operated the peripheral portion of the operation location desired. In the key input disease tendency process, When the cancel operation is performed, the previous operation can be determined as an erroneous operation.
(3) In the cancel operation determination process of FIG. 10, it is determined whether or not the cancel operation has been performed by performing the steps S62 to S65. However, the present invention is not limited to this. When determining the erroneous operation of the operation button that is close to the operation button position, the position of the operation button that has been switched and the position of the operation button that has been switched the previous time are close to each other in the next step of S65 (for example, A step (S65a) for determining whether or not it is within 5 mm may be inserted.

  Thereby, it is possible to accurately determine an erroneous operation of the operation button whose position is close.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
