Description

  The present invention relates to an operation state monitoring method, an operation state monitoring device, and a program for monitoring a user's operation state in an information terminal such as a personal computer or a mobile phone.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic diagram showing a network configuration having a server apparatus to which an operation state monitoring apparatus according to the present invention is applied.
As shown in FIG. 1, information terminals 2 a and 2 b are connected to the server device 1 via a communication network N.
The communication network N is a telephone network such as the Internet or a telecommunications carrier, a cellular phone communication network, and the like. Data communication is performed between the server device 1 connected to the communication network N and devices such as the information terminals 2a and 2b. Connect as possible.

The server device 1 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), a HDD (Hard Disk Drive), and the like (not shown). And the function as an operation state monitoring apparatus is implement | achieved by cooperation with the program memorize | stored in CPU and ROM.
Specifically, the server device 1 monitors the user's operation state (input accuracy and input speed) based on the operation information transmitted from the information terminal 2, estimates the user's fatigue state from this operation state, If it is determined that the user is tired, a message indicating that the user is tired is transmitted to the information terminal 2.

The information terminal 2a includes display means such as a liquid crystal panel and input means such as a keyboard and a mouse. The information terminal 2b is a mobile phone provided with display means such as a small liquid crystal panel and input means such as dial keys. In addition, as the information terminal, a device equipped with display means and input means such as PDA (Personal Digital Assistant) can be used. Hereinafter, the information terminals including the information terminals 2a and 2b will be collectively described as the information terminal 2.
The information terminal 2 includes a CPU, ROM, and RAM (not shown). The information terminal 2 collects operation information that is output when the user operates the input means in cooperation with the CPU and the program stored in the ROM, and transmits the operation information to the server device 1. Further, it receives a message transmitted from the server device 1 and displays this message on the display means.

FIG. 2 is an explanatory diagram showing functional configurations of the server device 1 and the information terminal 2.
As illustrated in FIG. 2, the information terminal 2 includes an operation unit 21, an operation information collection unit 22, an operation information transmission unit 23, a message reception unit 24, and a message notification unit 25.

  The operation unit 21 includes, for example, a pointing device such as a mouse or a keyboard on which a plurality of keys are arranged, and outputs operation information in accordance with a user operation. For example, when a key used for text input such as a keyboard character / number key, space key, enter key, delete key (DEL key), backspace key (BS key), etc. is pressed, it is unique to the key. Output key input information.

  The operation information collection unit 22 collects operation information output when the operation unit 21 is operated by the user. For example, when a key on the keyboard is pressed, individual key input information corresponding to the key is collected in an identifiable form.

The operation information transmission unit 23 transmits a series of operation information collected in a predetermined period by the operation information collection unit 22 to the server device 1. For example, a communication unit (not shown) that performs protocol processing such as TCP / IP (Transmission Control Protocol / Internet Protocol) and enables data communication with other devices (for example, the server device 1) connected to the network N. ) To send operation information. The operation information includes operation time information indicating the predetermined period together with key input information in order to calculate an input speed.
Here, the predetermined period may be a period until a predetermined time elapses after the input operation is started, or key input information (for example, enter key ( It may be until there is a key input information corresponding to the confirmation of Japanese input) or a space key (conversion of Japanese input). It is desirable to decide according to the text information input method such as Japanese input or English input.

The message receiving unit 24 receives a message transmitted from the server device 1. For example, a protocol process such as TCP / IP is performed, and a message is received via a communication unit (not shown) that enables data communication with another device (for example, the server device 1) connected to the network N. .
The message notification unit 25 is a display unit of the information device 2 and displays a message received by the message reception unit 24. For example, when a message is transmitted from the server device 1, the message receiving unit 24 automatically receives this, and the message notification unit 25 immediately displays the message.

  The functions of the operation information collection unit 22, operation information transmission unit 23, message reception unit 24, and message notification unit 24 are realized by the CPU of the information device 2 executing a program stored in the ROM.

  On the other hand, the server device 1 includes an operation information receiving unit 11, an operation information accumulation database (hereinafter referred to as operation information accumulation DB) 12, an input speed determination unit 13, an input accuracy determination unit 14, a message selection unit 15, and a message transmission unit 16. , A message database (hereinafter referred to as message DB) 17.

The operation information receiving unit 11 receives operation information (including key input information and operation time information) transmitted from the information terminal 2. For example, it performs protocol processing such as TCP / IP and receives operation information via a communication unit (not shown) that enables data communication with other devices (for example, the information terminal 2) connected to the network N. To do.
Further, the operation information receiving unit 11 determines the information terminal 2 that has transmitted the operation information from, for example, the IP address of the information terminal 2 or the like. The input speed determination unit 13 and the input accuracy determination unit 14 to be described later determine the operation state according to the specified information terminal (user) 2.

  The operation information accumulation DB 12 is configured by, for example, a hard disk, and the operation information (for example, text information) output from the operation information receiving unit 11 and information about the user's operation habits (hereinafter referred to as operation habit information) for each user. Remember. The operation habit information is sequentially updated based on the input speed (characters / minute) calculated by the input speed determination unit 13 described later and the input accuracy (%) calculated by the input accuracy determination unit 14.

  Here, the input speed is calculated from the number of pieces of key input information acquired during a predetermined period, and is expressed in terms of the number of characters input per minute, for example. The input accuracy is the frequency of occurrence of input mistakes, and is expressed, for example, as a ratio of key input information of the DEL key or BS key to the total number of key input information acquired in a predetermined period. That is, a case where a specific key such as a DEL key or a BS key is input is regarded as a user input error, and this is digitized to obtain input accuracy. For example, when there is no key input information corresponding to the DEL key or BS key, the input error is 0, that is, the input accuracy is 100%.

FIG. 3 is an explanatory diagram illustrating an example of a data configuration of the operation habit information stored in the operation information accumulation DB 12. The operation information storage DB 12 stores operation habit information for each user (for each information terminal 2).
As shown in FIG. 3, the operation information storage DB 12 stores average input accuracy and input speed calculated based on operation information transmitted from the same information terminal 2 in the past. Further, text information (text A, text B,...) Included in past operation information, that is, input accuracy and input speed for each text information input in the past is stored. The text information includes words, sentences, fixed phrases, and the like.

The input accuracy and input speed when the user is not tired at all (hereinafter referred to as the normal time) differ depending on the user. By storing this information as average operation habit information for each user, the current operation state for each user (Too tired, rushed, etc.) can be accurately judged.
For example, a beginner generally has a low input accuracy and a low input speed. On the other hand, a skilled person generally has high input accuracy and high input speed. Therefore, the current operation state is accurately determined according to the operation habit including the user's skill, and the fatigue level and the like are determined.

  In FIG. 2, the input speed determination unit 13 determines the level of the input speed based on the individual key input speeds calculated from the number of key input information acquired in a predetermined period by the operation information acquisition unit 11. For example, the calculated input speed is compared with a predetermined value set based on the average input speed stored in the operation information accumulation DB 12 to determine whether the input speed is high or low.

  The input accuracy determination unit 14 is based on the ratio of specific key input information (key input information corresponding to the DEL key or BS key) in the key input information acquired in a predetermined period by the operation information acquisition unit 11 (input accuracy ( The quality of the input error occurrence frequency) is determined. For example, the calculated input accuracy is compared with a predetermined value set based on the average input accuracy stored in the operation information accumulation DB 12, and the quality of the input accuracy is determined.

  The message selection unit 15 selects a predetermined message from the message DB based on the determination results in the input speed determination unit 13 and the input accuracy determination unit 14. For example, when the input accuracy determination unit 14 determines that the input accuracy is equal to or less than a predetermined value, a message indicating that the operation state has deteriorated is selected.

  The message transmission unit 16 transmits the message selected by the message selection unit 15 to the information terminal 2. For example, protocol processing such as TCP / IP is performed, and a message is transmitted via a communication unit (not shown) that enables data communication with another device (for example, the information terminal 2) connected to the network N. .

The message DB 17 is composed of, for example, a hard disk and stores a message notified to the information terminal 2.
FIG. 4 is an explanatory diagram illustrating an example of a message stored in the message DB 17.
As shown in FIG. 4, the message DB 17 stores a plurality of messages A, B,.
The message A is a message to be notified when the input accuracy determination unit 14 determines that the input accuracy is low (i.e., frequent input mistakes), that is, informs the user that the operation state has deteriorated. It is an example of a message.
The message B is a message to be notified when the input accuracy determination unit 14 determines that the input accuracy is lowered and the input speed determination unit 13 determines that the input speed is equal to or higher than a predetermined value, that is, It is an example of the message which tells a user that the operation state has deteriorated due to the input speed.

  As described above, the server device 1 according to the present embodiment is connected to the information terminal 2 via the network N, and the operation information acquisition unit (acquires operation information from the input unit (operation unit 21) of the information terminal 2). The operation information receiving unit 11) compares the average operation state of the user based on the operation information acquired in the past certain period with the current operation state based on the newly acquired operation information, and A message notification for notifying a user of a predetermined message based on an operation state determination unit (input speed determination unit 13, input accuracy determination unit 14) for determining a deterioration tendency and a deterioration tendency of the operation state determined by the operation state determination unit Means (message selection unit 15, message transmission unit 16).

  Specifically, the server device 1 includes an operation information storage database (12) that stores user operation habit information (input speed, input accuracy) based on operation information acquired by the operation information acquisition unit in a past fixed period. The operation state determination unit determines the current user operation state by comparing the operation information newly acquired by the operation information acquisition unit with the user's operation habit information stored in the operation information storage DB.

  The functions of the operation information receiving unit 11, the input speed determining unit 13, the input accuracy determining unit 14, the message selecting unit 15, and the message transmitting unit 16 described above are such that the CPU of the server device 1 executes a program stored in the ROM. It is realized by. The operation state monitoring process in the server device 1 is configured by arranging these functions in time series.

FIG. 5 is a flowchart illustrating an example of the operation state monitoring process in the server device 1.
In step S101, the operation information transmitted from the information terminal 2 is acquired (operation information receiving unit 11). Here, as the operation information, individual key input information input from a keyboard on which a plurality of keys are arranged and operation time information required for key input are acquired.

  In step S102, the input accuracy is calculated from the ratio of the key input information corresponding to the specific key (DEL key or BS key) in all the acquired key input information (input accuracy determination unit 14). For example, when 100 key input information is acquired and 20 of the key input information corresponds to a specific key, 20% is an input error and the input accuracy is 80%.

In step S103, it is determined whether or not the input accuracy calculated in step S102 is equal to or less than a predetermined value, that is, whether or not a large number of input errors have occurred as compared with the normal time (input accuracy determination unit 14).
Here, the predetermined value for determining the input accuracy is set based on the input accuracy stored as operation habit information in the operation information accumulation DB 12. For example, when it is determined that there are many input mistakes when the input accuracy is 20% lower than the average input accuracy stored in the operation information accumulation DB 12, the average stored in the operation information accumulation DB 12 is used. 80% of the input accuracy is a predetermined value.
As a result, it is possible to accurately determine whether or not the current input accuracy is good compared to the normal time.

At this time, the quality of the current input accuracy may be determined using only the average input accuracy stored in the operation information storage DB 12, or the input accuracy stored for each text information may be used. The current input accuracy may be determined. The user's input accuracy varies depending on the text information to be input (for example, in the case of a word with a large number of characters, the input accuracy is lower than that of a word with a short number of characters). The current input accuracy can be determined.
However, in this case, it is desirable to use the input accuracy as a criterion for determining the current input accuracy only for text information whose usage frequency is greater than or equal to the predetermined number from the history of operation information. This is because text information that is used less frequently does not always represent the user's operating habits, and is therefore inappropriate as a criterion.

  If it is determined in step S103 that the input accuracy is equal to or lower than the predetermined value, that is, if it is determined that there are more input errors than in the normal time, the process proceeds to step S104. On the other hand, if it is determined that the input accuracy is not less than the predetermined value, that is, if it is determined that the input error is within the range normally committed by the user, the process proceeds to step S109.

In step S104, it is determined whether the input accuracy is continuously below a predetermined value (input accuracy determination unit 14). In other words, if the input accuracy is less than the predetermined value in a single shot, it cannot be determined that the user's operation state has deteriorated, such as an accidental input error, so the input accuracy has continuously decreased below the predetermined value. In this case, it is determined that the user's operation state has deteriorated.
If it is determined that the input accuracy is continuously below the predetermined value, the process proceeds to step S105, and if it is determined that the input accuracy is not continuously below the predetermined value, the process proceeds to step S109.

  In step S105, a key input speed is calculated from the number of acquired key input information and operation time information (input speed determination unit 13). For example, assuming that one character is input by one key operation (for example, alphabet input), when 100 key input information is input in one minute, the input speed is 100 characters / minute. .

  In step S106, it is determined whether or not the input speed is equal to or higher than a predetermined value, that is, whether or not the input speed is too high compared to the normal time (input speed determination unit 13). Here, the predetermined value for determining the input speed is set based on an average input speed stored as operation habit information in the operation information accumulation DB 12. For example, when it is determined that the input speed is too high when the input speed exceeds 20% compared to the average input accuracy stored in the operation information accumulation DB 12, the input stored in the operation information accumulation DB 12 120% of the speed is a predetermined value.

At this time, the current input speed may be determined using only the average input speed stored in the operation information accumulation DB 12, or the input speed stored for each text information may be used. You may determine the present input speed level. It is considered that the input speed of the user changes depending on the text information to be input (for example, when a special key input such as a symbol is required, the input speed is lower than a simple key input such as an alphabet). Therefore, the current input speed can be accurately determined by taking this into consideration.
However, in this case, it is desirable to use the input speed as a criterion for determining the current input speed only for text information whose usage frequency is a predetermined number or more from the history of operation information. This is because text information that is used less frequently does not always represent the user's operating habits, so it is inappropriate to use it as a criterion.

  If it is determined in step S106 that the input speed is not equal to or higher than the predetermined value, that is, if it is determined that the input speed is within a range that can be predicted from the user's operating habits, the process proceeds to step S107. On the other hand, when it is determined that the input speed is equal to or higher than the predetermined value, that is, when it is determined that the input speed is too high than normal, the process proceeds to step S108.

  In step S107, the message A stored in the message DB 17 is notified (message selection unit 15, message transmission unit 16). That is, input errors exceeding the normal time occur continuously ("YES" in step S104), but if the input speed is about the normal time ("NO" in step S106), the input is caused by user fatigue. Since a mistake has occurred, a message A to the effect that the operation state of “a typo continues. This message A will be displayed on the display means of the information terminal 2.

  In step S108, the message B stored in the message DB 17 is notified (message selection unit 15, message transmission unit 16). That is, when input mistakes exceeding the normal time occur continuously (“YES” in step S104) and the input speed is too high (“YES” in step S106), the user is not tired. Since the input speed is too fast (key input is too fast), an input error has occurred, so the input is "It seems that you are typing too quickly. A message B indicating that the operation state has deteriorated due to the speed is transmitted to the information device 2. This message B is displayed on the display means of the information terminal 2.

In step S109, the current operation information (for example, text information) acquired by the operation information receiving unit 11, the input speed calculated by the input speed determining unit 13 corresponding thereto, and the input accuracy calculated by the input accuracy determining unit. Are stored in the operation information storage DB as operation habit information. At this time, when the operation habit information about the text information included in the acquired operation information is already stored in the operation information accumulation DB 12, the average of the input speed and the input accuracy corresponding to the text information is calculated. This is stored as new operation habit information.
Further, in step S109, from the average input speed and input accuracy already stored in the operation information accumulation DB and the input speed calculated by the input speed determination unit 13 and the input accuracy calculated by the input accuracy determination unit, A new average input speed and input accuracy are calculated and stored.

  In step S110, a predetermined value for determining the input speed and the input accuracy is reset from the input speed calculated by the input speed determination unit 13 and the input accuracy calculated by the input accuracy determination unit. When the operation information is acquired next time, the reset predetermined value becomes a determination criterion. Thereby, when the message is notified once to the information terminal 2, the predetermined value for determining the input speed and / or the input accuracy is reset and the determination criterion is lowered, so the message is frequently notified to the information terminal 2 and the user is notified. You can avoid feeling bothersome.

As described above, the server device 1 acquires operation information from the input means (operation unit 21) of the information terminal 2 (step S101), and determines the user's operation state based on the acquired operation information (step S101). S102 to S106), a predetermined message is notified to the user based on the determination result (steps S107 and S108).
In this way, the user is advised to take a break appropriately by accurately judging the fatigue level of the user who uses the information terminal 2 from direct information such as an input error without using a special device. be able to.

As a result, the user can recognize that he / she is tired and can prevent the input efficiency from being lowered by taking a break.
In addition, for businesses that provide WEB sites and the like, the user's fatigue can be moderately eliminated, and as a result, the user's access time can be extended, thereby increasing the advertising effect.

Moreover, the server apparatus 1 determines a user's operation state based on each key input information input from the keyboard as operation information. Specifically, whether or not the input accuracy is good is determined based on the ratio of the specific key input information to the key input information acquired during the predetermined period (step S103).
Thereby, the user's operation state, that is, whether or not the input accuracy with respect to the normal time (when not tired) can be accurately determined.

Further, the server device 1 stores operation habit information based on the past operation history (step S109), and sets a predetermined value for determining whether the current input accuracy is good or not based on the operation habit information (step S110). ).
Thereby, since the input mistake accompanying a user's operation habit and the input mistake accompanying a user's fatigue can be distinguished, the present operation state can be judged exactly. In addition, it is possible to cope with a change in the skill level of the user.

Furthermore, the server device 1 calculates individual key input speeds from the number of key input information acquired in a predetermined period (step S105), and determines the level of the input speed based on this. When the input accuracy is worse than normal and the input speed is higher than normal, the user is notified that the operation state is deteriorated due to the input speed.
As a result, the user can recognize whether an input error has occurred due to fatigue or has occurred too quickly, so that the input error can be reduced by taking appropriate measures (such as taking a break or calming down). Can do.

  In the operation state management process shown in FIG. 5, the user's operation state is determined based on the degree of input accuracy and input speed. However, in FIG. 5, step S105 and step S106 are omitted, and only from the input accuracy. The operation state may be determined and a message may be notified.

Further, the message may be notified by determining the operation state of the user based on the degree of the input speed.
FIG. 6 is a flowchart illustrating another example of the operation state monitoring process in the server device 1.

  In step S201, the operation information transmitted from the information terminal 2 is acquired (operation information receiving unit 11). Here, as the operation information, individual key input information input from a keyboard on which a plurality of keys are arranged and operation time information required for key input are acquired.

  In step S202, a key input speed is calculated from the number of acquired key input information and operation time information (input speed determination unit 13). For example, assuming that one character is input by one key operation (for example, alphabet input), when 100 key input information is input in one minute, the input speed is 100 characters / minute. .

  In step S203, it is determined whether or not the input speed is equal to or lower than a predetermined value, that is, whether or not the input speed is too slow compared to the normal time (input speed determination unit 13). Here, the predetermined value for determining the input speed is set based on an average input speed stored as operation habit information in the operation information accumulation DB 12. For example, when it is determined that the input speed is reduced when the input speed is 20% lower than the average input speed stored in the operation information accumulation DB 12, it is stored in the operation information accumulation DB 12. 80% of the average input speed is a predetermined value.

  At this time, the current input speed may be determined using only the average input speed stored in the operation information accumulation DB 12, or the input speed stored for each text information may be used. You may determine the present input speed level.

  If it is determined in step S203 that the input speed is equal to or lower than the predetermined value, that is, if it is determined that the input speed is too slow than normal, the process proceeds to step S204. On the other hand, if it is determined that the input speed is not less than or equal to the predetermined value, that is, if it is determined that the input speed is within a range that can be predicted from the user's operating habits, the process proceeds to step S206.

In step S204, it is determined whether the input speed is continuously equal to or lower than a predetermined value (input speed determination unit 13). In other words, when the input speed is a single shot or less than the predetermined value, the information to be input is complicated (for example, when special key input such as symbols is required), etc. Therefore, it is determined that the user's operation state has deteriorated when the input speed continuously falls below a predetermined value.
If it is determined that the input speed is continuously lower than the predetermined value, the process proceeds to step S205. If it is determined that the input speed is not continuously lower than the predetermined value, the process proceeds to step S206.

  In step S205, the message C stored in the message DB 17 is notified (message selection unit 15, message transmission unit 16). That is, when the input speed is clearly reduced compared with the normal time (“YES” in step S204), it is considered that the input speed is reduced due to user fatigue. A message C indicating that the operation state has deteriorated is transmitted to the information device 2. This message C is displayed on the display means of the information terminal 2.

In step S206, the current operation information (for example, text information) acquired by the operation information receiving unit 11 and the input speed calculated by the input speed determining unit 13 corresponding thereto are stored in the operation information storage DB as operation habit information. Remember. At this time, when the operation habit information about the text information included in the acquired operation information is already stored in the operation information accumulation DB 12, an average with the input speed corresponding to the text information is calculated, and this is calculated. It will be memorized as new operation habit information.
In step S206, a new average input speed is calculated and stored from the average input speed already stored in the operation information accumulation DB and the input speed calculated by the input speed determination unit 13.

  In step S207, a predetermined value for determining the input speed is reset from the input speed calculated by the input speed determination unit 13. When the operation information is acquired next time, the reset predetermined value becomes a determination criterion. As a result, when a message is notified once to the information terminal 2, the predetermined value for determining the input speed is reset and the determination criterion is lowered, so the message is frequently notified to the information terminal 2 and the user feels bothered. Can be avoided.

As described above, the server device 1 acquires operation information from the input means (operation unit 21) of the information terminal 2 (step S201), and determines the user's operation state based on the acquired operation information (step S201). S202 to S204), a predetermined message is notified to the user based on the determination result (step S205).
In this way, the user is advised to take a moderate break by accurately judging the fatigue level of the user who uses the information terminal 2 from the direct information that the input speed is reduced without using a special device. Can do.

As a result, the user can recognize that he / she is tired and can prevent the input efficiency from being lowered by taking a break.
In addition, for businesses that provide WEB sites and the like, the user's fatigue can be moderately eliminated, and as a result, the user's access time can be extended, thereby increasing the advertising effect.

Moreover, the server apparatus 1 determines a user's operation state based on each key input information input from the keyboard as operation information. Specifically, the level of the input speed is determined based on the input speed calculated from the key input information acquired during the predetermined period (step S203).
Thereby, it is possible to accurately determine the level of the input speed with respect to the user's operation state, that is, the normal time (when not tired).

Further, the server device 1 stores operation habit information based on the past operation history (step S206), and sets a predetermined value for determining the current input speed based on the operation habit information (step S207). ).
As a result, it is possible to distinguish between a decrease in input speed due to the user's operating habits and a decrease in input speed due to user fatigue, so the current operating state can be accurately determined. In addition, it is possible to cope with a change in the skill level of the user.
If the operation state management process shown in FIGS. 5 and 6 is used in combination, it is possible to notify the user of more accurate advice.

  As mentioned above, although the invention made | formed by this inventor was concretely demonstrated based on embodiment, this invention is not limited to the said embodiment, It can change in the range which does not deviate from the summary.

For example, in the above embodiment, the operation state monitoring process is executed in the server device 1 based on the operation information transmitted from the information terminal 2, but the operation state management process is executed in the information terminal 2. May be.
In this case, a program for realizing the operation state monitoring process is stored in the hard disk of the information terminal 2, and the CPU executes this program. Further, it is necessary to provide the operation information accumulation DB 12 and the message DB 17 of FIG.

Further, the types of messages notified to the information terminal 2 are not limited to those shown in the above embodiment, and various forms are conceivable. For example, you may make it notify a user of the deterioration of an operation state with an audio | voice.
Furthermore, if the input accuracy and input speed are determined in multiple stages and a message corresponding to the determination result is appropriately notified, it is possible to flexibly cope with the user's operation state.

In the above embodiment, the user's operation state is determined based on the key operation information from the keyboard of the personal computer or the dial key of the mobile phone. However, the user's operation state is determined based on the operation information from the pointing device such as a mouse. It is also possible to determine the operation state.
For example, in a WEB browser or the like, it is possible to determine that the operation state has deteriorated when a text or image for which a link is set cannot be selected with one click (the position of the pointer is shifted).

In the above description, an example in which a ROM is used as a computer-readable medium storing a program according to the present invention is disclosed, but the present invention is not limited to this example.
For example, as other computer-readable media, a non-volatile memory such as a flash memory and a portable recording medium such as a CD-ROM can be applied. Further, a carrier wave (carrier wave) is also applied to the present invention as a medium for providing program data according to the present invention via a communication line.
