[0013] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same or equivalent elements are designated by the same reference numerals, and duplicated descriptions will be omitted.

[0014] [System Overview] The evaluation system according to the present disclosure is a computer system that evaluates the dexterity of a subject's penmanship based on writing data from a task of filling in an area with a writing implement. A penmanship refers to the movement of the body when using a writing implement, for example, the movement of the hand, finger, elbow, or arm when writing a character or drawing a figure with a writing implement. The dexterity of a penmanship refers to an index showing the degree of dexterity and precision of a penmanship. That is, the dexterity of a penmanship is an index showing how precisely a subject can control a writing implement. The dexterity of a penmanship is also called "penmanship dexterity." A subject refers to a person whose penmanship dexterity is evaluated by the evaluation system. The subject may be, for example, an infant, a child, an adult, or an elderly person. The evaluation system may be used in various situations such as education, research, examination, and clinical practice. For example, the evaluation system may be used to evaluate the developmental status or writing ability of a child or an adult, or to evaluate the brain function or motor function of an elderly person or a patient after surgery.

[0015] The subject is provided with a medium for performing the filling-in task. The medium may be paper or an electronic device with a touch screen, such as a tablet or pen tablet. One or more areas are shown on the medium. An area is a designated portion to be filled in with a writing implement. An area may be a portion surrounded by a frame of a predetermined shape, such as a circle or a polygon. When multiple areas are provided, the shapes and sizes of the areas may be uniform, or at least one of the shapes and sizes may be different between at least two areas.

[0016] Writing data is generated by the subject's filling-in task, and the evaluation system evaluates the penmanship dexterity based on this writing data. The writing data refers to information about writing measured during the filling-in task. The writing data is expressed as time-series data showing the change over time of at least one parameter related to the writing implement during the filling-in task. The parameters are physical quantities such as writing pressure, speed, acceleration, angular velocity, angular acceleration, position, inclination, and pressure to hold the writing implement. The writing data may be measured by the writing implement or medium, or may be measured by a measuring device separate from the writing implement and medium.

[0017] [System configuration] FIG. 1 is a diagram showing an example of application of an evaluation system 1 according to an embodiment. In this example, the evaluation system 1 includes a terminal 10. The terminal 10 is connected to a writing implement 20 by short-range wireless communication, and is connected to a database 30 via a communication network N. The short-range wireless communication may be a communication method such as Bluetooth (registered trademark) or Wi-Fi (registered trademark). The communication network N may be configured to include, for example, the Internet or an intranet. In this example, the evaluation system 1 evaluates penmanship dexterity based on writing data in an operation of filling in three areas 41 on a sheet of paper 40.

[0018] The terminal 10 is a computer that evaluates the penmanship dexterity of a subject. The terminal 10 may be a portable terminal such as a high-performance mobile phone (smartphone), a tablet terminal, a wearable terminal (e.g., a head-mounted display (HMD), smart glasses, or a smart watch), a laptop personal computer, or a mobile phone. Alternatively, the terminal 10 may be a stationary terminal such as a desktop personal computer.

[0019] The writing instrument 20 is a tool used for writing characters, symbols, illustrations, and the like. The writing instrument 20 may be a pen capable of writing with ink or graphite, such as a pencil, a ballpoint pen, a fountain pen, a marker, and a mechanical pencil, or a pointing device such as a stylus. The writing instrument 20 may be a sensor pen capable of measuring at least one parameter to generate writing data. In the example of FIG. 1, one writing instrument 20 communicates with the terminal 10, but two or more writing instruments 20 may communicate with one terminal 10.

[0020] The database 30 is a non-transitory storage device that stores various data used by the evaluation system 1. The database 30 may be constructed as a single database, or may be a collection of multiple databases.

[0021] 2 is a diagram showing an example of a hardware configuration related to the evaluation system 1. FIG. 2 shows a terminal computer 100 functioning as the terminal 10.

[0022] As an example, the terminal computer 100 includes, as hardware components, a processor 101, a main memory unit 102, an auxiliary memory unit 103, a communication unit 104, an input interface 105, and an output interface 106.

[0023] The processor 101 is a computing device that executes an operating system and application programs. For example, the processor 101 is a CPU or a GPU.

[0024] The main memory unit 102 is a device that stores programs for implementing the terminal 10, calculation results output from the processor 101, etc. The main memory unit 102 is configured with at least one of a ROM and a RAM, for example.

[0025] The auxiliary storage unit 103 is generally a device capable of storing a larger amount of data than the main storage unit 102. The auxiliary storage unit 103 is configured by a non-volatile storage medium such as a hard disk, a flash memory, etc. The auxiliary storage unit 103 stores a client program P1 for causing the terminal computer 100 to function as the terminal 10 and various data.

[0026] The communication unit 104 is a device that executes data communication with other computers via the communication network N. The communication unit 104 is configured by, for example, a network card or a wireless communication module.

[0027] The input interface 105 is a device that accepts data based on a user's operation or action. For example, the input interface 105 is configured with at least one of a keyboard, an operation button, a pointing device, a microphone, a sensor, and a camera. The keyboard and the operation button may be displayed on a touch panel.

[0028] The output interface 106 is a device that outputs data processed by the terminal computer 100. For example, the output interface 106 is composed of at least one of a monitor, a touch panel, an HMD, and a speaker.

[0029] Each functional element of the terminal 10 is realized by loading a client program P1, which is an example of an evaluation program, into the processor 101 or the main memory unit 102 and having the processor 101 execute the program. The client program P1 includes code for realizing each functional element of the terminal 10. The processor 101 operates the communication unit 104, the input interface 105, or the output interface 106 in accordance with the client program P1, and reads and writes data in the main memory unit 102 or the auxiliary memory unit 103. Each functional element of the terminal 10 is realized by this processing.

[0030] The client program P1 may be provided in a state where it is non-temporarily recorded on a tangible recording medium such as a CD-ROM, a DVD-ROM, a semiconductor memory, etc. Alternatively, the client program P1 may be provided via a communication network as a data signal superimposed on a carrier wave.

[0031] FIG. 3 is a diagram showing an example of a functional configuration related to the evaluation system 1. The terminal 10 includes a communication unit 11, a calculation unit 12, a judgment unit 13, and an evaluation unit 14 as functional elements. The communication unit 11 is a functional element that transmits and receives various data between the writing implement 20 and the database 30. The communication unit 11 functions as an acquisition unit that acquires writing data. The calculation unit 12 is a functional element that calculates a statistical value based on the writing data. The judgment unit 13 is a functional element that judges whether the statistical value satisfies a predetermined standard. The evaluation unit 14 is a functional element that evaluates the penmanship dexterity of the subject based on the result of the judgment by the judgment unit 13.

[0032] Writing instrument 20 includes, as functional elements, a measurement unit 21 and a communication unit 22. Measurement unit 21 is a functional element that measures at least one parameter related to writing instrument 20 and generates writing data based on the measurement result. Communication unit 22 is a functional element that transmits and receives various data to and from terminal 10. These functional elements are realized by a processor of writing instrument 20.

[0033] In one example, the database 30 stores, in addition to the subject's handwriting data, subject data, statistical data, reference data, sample data, judgment data, and evaluation data. The subject data is data indicating the subject's attributes. The statistical data is data indicating statistical values ​​calculated based on the handwriting data. The reference data is data indicating standards used to judge statistical values. The sample data is handwriting data obtained from people collected as a sample, and is used to set standards. The judgment data is data indicating the results of judgment based on the statistical values ​​and standards. The evaluation data is data indicating the results of evaluation of penmanship dexterity. In one example, the database 30 stores the handwriting data, subject data, statistical data, judgment data, and evaluation data for each subject.

[0034] [System Operation] The operation of the evaluation system 1 will be described with reference to Fig. 4. Fig. 4 is a flow chart showing an example of the operation as a process flow S1. In the following, writing pressure, speed, and angular velocity are exemplified as parameters related to the writing implement 20.

[0035] In step S11, the communication unit 11 acquires writing data during the filling-in task by the subject. The writing data indicates a change over time in at least one parameter related to the writing implement 20.

[0036] The subject receives instructions such as "Please fill in carefully," and performs the task of filling in each area 41 using the writing instrument 20. In the writing instrument 20, the measurement unit 21 acquires data indicating the change over time in the parameters of the writing pressure, speed, and angular velocity during the task as writing data. The writing pressure refers to the pressure generated at the tip (i.e., the pen tip) of the writing instrument 20 pressed against a medium such as paper 40. The speed refers to the speed of movement of a predetermined portion of the writing instrument 20. The portion may be, for example, the center or the tip of the writing instrument 20. The angular velocity is the angular velocity of the writing instrument 20 measured around an axis passing through the writing instrument 20, and is measured for each of the three axes of the writing instrument 20. The measurement unit 21 measures a first angular velocity (GyroX), which is an angular velocity centered on a first axis along a direction from the tip to the rear end of the writing instrument 20, a second angular velocity (GyroY), which is an angular velocity centered on a second axis perpendicular to the first axis, and a third angular velocity (GyroZ), which is centered on a third axis perpendicular to the first and second axes.

[0037] In one example, while the subject is filling in each area 41 with the writing implement 20, the measurement unit 21 measures or calculates the writing pressure, velocity, and angular velocity at a predetermined sampling frequency. The sampling frequency may be 100 Hz, in which case the measurement unit 21 measures the writing pressure, velocity, and angular velocity at 0.01 second intervals. The measurement unit 21 measures the writing pressure using a pressure sensor or load sensor, measures or calculates the velocity using a velocity sensor or acceleration sensor, and measures or calculates the angular velocity using a gyro sensor. Then, the measurement unit 21 generates a set of writing pressure data indicating a change in the writing pressure over time, velocity data indicating a change in the velocity over time, and angular velocity data indicating a change in the angular velocity over time as writing data. The angular velocity data indicates a first angular velocity, a second angular velocity, and a third angular velocity.

[0038] The communication unit 22 transmits the handwritten data to the terminal 10. The communication unit 11 receives the handwritten data. The communication unit 11 associates the handwritten data with a subject ID, which is an identifier for identifying the subject. The communication unit 11 may read out the subject ID from the subject data in the database 30, or may accept the subject ID via the input interface 105. The communication unit 11 may store the handwritten data associated with the subject ID in the database 30.

[0039] In step S12, the calculation unit 12 calculates one or more intra-task statistical values ​​for each parameter based on the acquired handwriting data. The intra-task statistical value refers to a statistical value of a parameter in the task of filling in a predetermined number of areas. When there are multiple areas like the paper 40, the calculation unit 12 may calculate an intra-task statistical value for each of the multiple areas, and calculate the intra-task statistical value based on the multiple intra-task statistical values. The intra-task statistical value refers to a statistical value of a parameter in the task of filling in one area. In the example of FIG. 1, the calculation unit 12 calculates an intra-task statistical value of the parameter for each of the three areas 41, and calculates the intra-task statistical value based on the three intra-task statistical values.

[0040] The intra-task statistical value may be at least one of a representative value and a variance. The representative value may be, for example, the mean, median, maximum value, minimum value, mode, quartile, or 100α percentile for any α (0≦α≦1). The variance is a value indicating how dispersed the data is, and may be, for example, a standard deviation, a variance, an interquartile range, a range from the minimum value to the maximum value (variation range), a coefficient of variation, a mean absolute deviation, or a median absolute deviation. When there are two or more types of parameters, the types or numbers of statistical values ​​used as intra-task statistical values ​​may differ between at least two types of parameters.

[0041] Based on the writing data, the calculation unit 12 specifies, for each of the one or more regions, a time span from the start to the end of the filling-in task of the region as a task time, and retains the writing data for the task time. This writing data may be a combination of writing pressure data, speed data, and angular velocity data. For example, the calculation unit 12 discards writing data for a time period in which the writing pressure is 15 g or less, and retains writing data for the remaining one or more task times. It can be said that the retained writing data is writing data for each of the one or more regions. The calculation unit 12 calculates one or more intra-task statistics based on the writing data for each region.

[0042] A procedure for calculating the in-task statistical value of pen pressure will be described. In one example, the calculation unit 12 calculates, for each region 41, the average value of a plurality of pen pressures obtained at a predetermined sampling period, which are indicated by the pen pressure data corresponding to the region 41, as the in-task average value. The calculation unit 12 calculates the in-task statistical value based on a plurality of in-task average values ​​corresponding to the plurality of regions 41. In one example, the calculation unit 12 calculates, as the in-task statistical value, an in-task average value which is the average value of the plurality of in-task average values, and a standard deviation of the in-task average value. Hereinafter, the in-task average value of pen pressure is also referred to as the pen pressure average value, and the standard deviation of pen pressure is also referred to as the pen pressure standard deviation.

[0043] Similar to the pen pressure, the calculation unit 12 calculates an in-job average value and a standard deviation for the speed based on the speed data of each region 41. Hereinafter, the in-job average value of the speed is also referred to as the speed average value, and the standard deviation of the speed is also referred to as the speed standard deviation.

[0044] The calculation unit 12 calculates an in-task average value and a standard deviation for the angular velocity based on the angular velocity data of each region 41, similarly to the pen pressure. The angular velocity as a parameter may be expressed using at least one of a first angular velocity (GyroX), a second angular velocity (GyroY), and a third angular velocity (GyroZ). For example, the calculation unit 12 may select one of the angular velocities of three axes as the angular velocity as the parameter. Alternatively, the calculation unit 12 may express the product of the angular velocities of the three axes (i.e., (GyroX)×(GyroY)×(GyroZ)) or the sum of the angular velocities of the three axes (i.e., (GyroX)+(GyroY)+(GyroZ)) as the angular velocity. Alternatively, the calculation unit 12 may express the square root of the sum of the squares of the angular velocities of the three axes (i.e., √{(GyroX) 2 +(GyroY) 2 +(GyroZ) 2}) may be expressed as an angular velocity. In any case, the calculation unit 12 calculates the intra-task average value and the standard deviation of the angular velocity as a parameter. Hereinafter, the intra-task average value of the angular velocity is also referred to as the angular velocity average value, and the standard deviation of the angular velocity is also referred to as the angular velocity standard deviation.

[0045] The calculation unit 12 may calculate a maximum value, a minimum value, or a variation range of data for at least one of the pen pressure, the velocity, and the angular velocity as an intra-task statistical value.

[0046] The calculation unit 12 may generate statistical data by associating each intra-task statistical value with a subject ID, and store this statistical data in the database 30. For example, the calculation unit 12 stores in the database 30 statistical data indicating the correspondence between the subject ID and a combination of the pen pressure average value, the pen pressure standard deviation, the velocity average value, the velocity standard deviation, the angular velocity average value, and the angular velocity standard deviation.

[0047] In step S13, the determination unit 13 determines whether or not each intra-operation statistical value satisfies a predetermined criterion.

[0048] The criterion is set for each intra-task statistical value. The individual criterion may be set for each attribute of the subject, such as age, age group, schooling stage, gender, various experiences, etc., or may be set independently of the attribute. The criterion may be set by a numerical range defined by a lower limit and an upper limit. In this case, the determination unit 13 determines that the criterion is satisfied if the intra-task statistical value is within the numerical range, and determines that the criterion is not satisfied if the intra-task statistical value is not within the numerical range. As another example, the determination unit 13 may determine that the criterion is satisfied if the intra-task statistical value is outside the numerical range, and determines that the criterion is not satisfied if the intra-task statistical value is not within the numerical range. Alternatively, the criterion may be set by a single lower limit. In this case, the determination unit 13 determines that the criterion is satisfied if the intra-task statistical value is equal to or greater than the lower limit, and determines that the criterion is not satisfied if the intra-task statistical value is not within the numerical range. Alternatively, the criterion may be set by a single upper limit. In this case, the determination unit 13 determines that the criterion is satisfied if the intra-task statistical value is equal to or less than the upper limit, and determines that the criterion is not satisfied if the intra-task statistical value is not within the numerical range. Hereinafter, the numerical range, lower limit value, and upper limit value set as the standard will also be referred to as the standard range, standard lower limit value, and standard upper limit value, respectively.

[0049] In one example, each criterion is set using sample data in the database 30. For example, the sample data is grouped by age, and a criterion is set for each age as follows: an intra-task statistic is calculated for each sample corresponding to that age, and outliers are removed based on the interquartile range of the intra-task statistic. Then, a criterion is set based on the group of remaining intra-task statistic values. For example, the criterion may be set based on the mean μ and standard deviation σ for the group of remaining intra-task statistic values. For example, a range of μ±2σ may be set as the reference range of the intra-task statistic value. Alternatively, μ-2σ may be set as the reference lower limit, and μ+2σ may be set as the reference upper limit.

[0050] Each set criterion is stored in advance as criterion data in the database 30. The criterion may be set by a computer other than the terminal 10 and stored in the database 30. Alternatively, the determination unit 13 may read sample data from the database 30 and set each criterion based on the sample data by the above-mentioned method.

[0051] The determination unit 13 determines whether or not each intra-task statistical value of each parameter satisfies a criterion. For example, the determination unit 13 may determine whether or not the pen pressure average value is within a reference range, may determine whether or not the pen pressure average value is equal to or greater than a reference lower limit, or may determine whether or not the pen pressure average value is equal to or less than a reference upper limit. The determination unit 13 similarly performs determinations using the corresponding criteria for the pen pressure standard deviation, the velocity average value, the velocity standard deviation, the angular velocity average value, and the angular velocity standard deviation.

[0052] Regarding the angular velocity, the determination unit 13 may perform the following determination. In one example, the determination unit 13 may determine that the criterion is met if the maximum value exceeds the reference upper limit value, and may otherwise determine that the criterion is not met. Alternatively, the determination unit 13 may determine that the criterion is met if the minimum value is less than the reference lower limit value, and may otherwise determine that the criterion is not met. As yet another example, the determination unit 13 may calculate the sum of the absolute values ​​of the lower limit value and the upper limit value of the fluctuation range, and may determine that the criterion is met if the sum exceeds the reference upper limit value, and may otherwise determine that the criterion is not met.

[0053] The determination unit 13 may generate determination data by associating the determination result with the subject ID, and store this determination data in the database 30. For example, the determination unit 13 stores in the database 30 determination data indicating the correspondence between the subject ID and a combination of the determination results regarding the pen pressure average value, the pen pressure standard deviation, the velocity average value, the velocity standard deviation, the angular velocity average value, and the angular velocity standard deviation.

[0054] In step S14, the evaluation unit 14 evaluates the penmanship dexterity of the subject based on the result of the judgment for each intra-task statistical value. In one example, the evaluation unit 14 expresses the evaluation result using an evaluation value that is an index for estimating whether the penmanship dexterity is appropriate or not.

[0055] The evaluation unit 14 may set a first evaluation value as dexterity when each intra-task statistical value of each parameter meets the criterion, and may set a second evaluation value indicating that the dexterity is lower than the first evaluation value when at least one intra-task statistical value does not meet the criterion. That is, the evaluation unit 14 sets a first evaluation value when all intra-task statistical values ​​meet the criterion, and sets a second evaluation value when at least a part of one or more intra-task statistical values ​​does not meet the criterion. The first evaluation value and the second evaluation value may be expressed as "high" and "low", respectively. As an example, the intra-task statistical values ​​are a pen pressure average value, a pen pressure standard deviation, a velocity average value, a velocity standard deviation, an angular velocity average value, and an angular velocity standard deviation. The evaluation unit 14 sets a first evaluation value when all of these six intra-task statistical values ​​meet the criterion, and sets a second evaluation value when at least one intra-task statistical value does not meet the criterion. In other words, if all of the intra-task statistical values ​​for pen pressure, speed, and angular velocity meet the criteria, the evaluation unit 14 judges the subject's penmanship dexterity to be relatively high, and if any of the intra-task statistical values ​​do not meet the criteria, the evaluation unit 14 evaluates the subject's penmanship dexterity to be relatively low.

[0056] Alternatively, the evaluation unit 14 may set the evaluation value according to the number of intra-task statistics that do not satisfy the criteria. Alternatively, the evaluation unit 14 may perform weighting on the judgment results of the intra-task statistics to determine a score, and set the evaluation value based on the sum of the scores.

[0057] The evaluation unit 14 outputs the set evaluation value. For example, the evaluation unit 14 may display the evaluation value on a monitor or may transmit the evaluation value to another computer. Alternatively, the evaluation unit 14 may generate evaluation data by associating the evaluation value with a subject ID and store the evaluation data in the database 30.

[0058] [Variations] Various examples of the present disclosure have been described in detail above. However, the present disclosure is not limited to the above examples. Various modifications of the present disclosure are possible without departing from the spirit and scope of the present disclosure.

[0059] The evaluation system may process the task time, which is the time span from the start to the end of a task of filling in one area, as a parameter related to the writing implement. The evaluation system may execute processing for the task time in the same manner as the pen pressure, speed, and angular velocity in the above example. That is, the calculation unit may calculate an intra-task statistical value for the task time based on the writing data, the determination unit may determine whether the intra-task statistical value satisfies a predetermined standard, and the evaluation unit may evaluate the penmanship dexterity of the subject based on the determination result.

[0060] In this disclosure, the expression "at least one processor executes a first process, executes a second process, ... executes an nth process" or a corresponding expression indicates a concept including a case where the executing entity (i.e., the processor) of n processes from the first process to the nth process changes midway. In other words, this expression indicates a concept including both a case where all of the n processes are executed by the same processor and a case where the processor changes among the n processes according to an arbitrary policy.

[0061] The processing procedure of the method executed by at least one processor is not limited to the above example. For example, some of the above steps may be omitted, or each step may be executed in a different order. In addition, any two or more of the above steps may be combined, or some of the steps may be modified or deleted. Alternatively, other steps may be executed in addition to the above steps.

[0062] In comparing the magnitude of two numerical values, either of the two criteria "greater than or equal to" or "greater than" may be used, or either of the two criteria "less than or equal to" or "less than".

(Appendix 8) an acquisition step of acquiring writing data indicating a change over time of at least one parameter related to the writing tool during an activity in which a subject fills in at least one area using the writing tool, the at least one parameter including at least a writing pressure of the writing tool; a calculation step of calculating, for each of the at least one parameter, at least one statistical value of the parameter in the task as at least one intra-task statistical value based on the handwritten data; a determining step for determining, for each of the at least one intra-task statistic for the at least one parameter, whether the intra-task statistic satisfies a predetermined criterion corresponding to the intra-task statistic; an evaluation step of evaluating dexterity of the subject's penmanship action based on the result of the determination for each of the at least one intra-task statistics for the at least one parameter; An evaluation program that causes a computer to execute the above.

[0064] According to Supplementary Notes 1, 7, and 8, a statistical value of the writing pressure in a filling-in task is calculated based on writing data that indicates at least a time-dependent change in the writing pressure of the writing implement used by the subject in the filling-in task, and the dexterity of the subject's writing action is evaluated based on the statistical value. The writing pressure in a filling-in task is likely to reflect the ability related to writing actions. By using the statistical value of the writing pressure, the dexterity of the subject's writing action can be appropriately evaluated.

[0065] According to Appendix 2, intra-task statistics are calculated based on the writing data from the task of filling in multiple areas, making it possible to evaluate the subject's penmanship dexterity with greater accuracy by taking into account the unevenness of each filling-in task.

[0066] According to Supplementary Note 3, an intra-area representative value is calculated for each of the multiple areas, and an intra-task representative value and the variance of the intra-area representative value are calculated as intra-task statistics based on the intra-area representative value. By taking both the representative value and the variance into consideration in this way, the examinee's penmanship dexterity can be evaluated in more detail.

[0067] According to Supplementary Note 4, when all intra-task statistics satisfy a predetermined standard, a first evaluation value is set as the penmanship dexterity, and when at least a part of the intra-task statistics does not satisfy the predetermined standard, a second evaluation value is set as the penmanship dexterity. This allows the penmanship dexterity to be evaluated relatively strictly, thereby reducing the risk that problems with the examinee's penmanship dexterity will be overlooked.

[0068] According to Appendix 5, the subject's dexterity is evaluated based on the speed of the writing implement. The speed particularly reflects the movements of the subject's hand, fingers, elbow and arm. Therefore, by further taking the speed into consideration, the subject's dexterity can be evaluated more accurately.

[0069] According to Appendix 6, the test subject's dexterity is evaluated based on the angular velocity around the axis passing through the writing implement. The angular velocity particularly reflects the motion of the test subject's hand, fingers, elbow and arm. Therefore, by further taking the angular velocity into consideration, the test subject's dexterity can be evaluated with greater accuracy. [Explanation of symbols]
