Hereinafter, embodiments of the information processing apparatus will be described with reference to the drawings.
[A] Description of First Embodiment FIG. 1 is a diagram showing a configuration of an information processing apparatus according to a first embodiment of the present invention. An information processing apparatus 1 (data processing apparatus; display apparatus) shown in FIG. 1 is, for example, a PC (Personal Computer), and performs various types of information processing. Here, the information processing apparatus 1 includes, for example, a CPU (Central Processing Unit) 2, a storage unit 3, an input unit 4, a display unit 5, and a bus 6. The CPU 2, the storage unit 3, the input unit 4, and the display unit 5 are connected to each other via a bus 6 so as to communicate with each other.

The storage unit 3 is, for example, an HDD (Hard Disk Drive) or an SSD (Solid State Drive), and stores various types of information. The storage unit 3 stores, for example, a measurement data folder 31 created by a motion recorder (not shown). That is, the storage unit 3 functions as a storage unit.
FIG. 2 is a diagram showing information created by the motion recorder. Here, a motion recorder (not shown) is information resulting from motion acceleration such as acceleration, speed, movement distance in the three-axis directions of the X, Y, and Z axes in the three-dimensional space of the measurement target such as the measurement subject. In addition to measuring time-sequential information (X data, Y data, Z data), a measurement data folder 31 is created and stored in a storage device such as an SD (Secure Digital) card provided by the motion recorder itself. Record the data. For example, the motion recorder is attached to the measurement subject's waist, but is not limited thereto, and may be attached to an arm or the like.

FIG. 2A is a diagram for explaining the measurement data folder 31.
The measurement data folder 31 is a folder created by the motion recorder, and holds one or more data files 32 and a header file 33. The measurement data folder 31 holds a subfolder (not shown). The subfolder holds information such as a motion recorder device number, motion recorder firmware version information, and gravity correction information.

The data file 32 is a file having measurement data such as acceleration measured by the motion recorder.
Here, the motion recorder divides and records the measurement data into a plurality of data files when the measurement data exceeds a predetermined capacity. That is, the motion recorder creates at least one or more data files 32 according to the measured information capacity. Here, in one data file 32 created by the motion recorder, measurement information in a predetermined time range determined in advance is recorded. That is, one data file 32 records measurement data of a predetermined number of points.

  Note that the file name of each data file 32 created by the motion recorder includes, for example, a date when measurement is started and file connection information. Here, the file connection information is information indicating the number of the data file 32 created from the start of measurement by the motion recorder. For example, if two data files are generated by the motion recorder on May 8, 2010, the file names of these data files 32 are “1005080001” and “1005080002”, respectively. Here, the first four digits of the file name indicate the date when the acceleration information or the like was measured by the motion recorder, that is, the date when the data file was created. Furthermore, the last four digits of the file name are file connection information, “0001” indicates that the data file was created first from the start of measurement, and “0002” is the data created first. Indicates that the data file follows the file. That is, the measurement data recorded in the group of data files 32 in which the file connection information is continuous is measurement data obtained by one measurement.

  When the measurement is stopped and the next measurement is started, for example, “0003” is skipped and “0004” is used as the file connection information. Thereby, file connection information does not continue, and the information processing apparatus 1 can accurately recognize a group of data files obtained by one measurement. The file name of the data file 32 is not limited to the above file name.

FIG. 2B is a diagram for explaining the header file 33.
The header file 33 is a file created by the motion recorder and is a file having measurement conditions. The header file 33 holds a measurement start time 331, start file information 332, a calibration value 333, and a sensor coefficient 334.
The measurement start time 331 is information indicating the date and time when measurement of acceleration information or the like was started by the motion recorder.

The start file information 332 is information indicating file connection information of the data file 32 created first after the start of measurement.
The calibration value 333 is a value for calibrating the variation of the motion recorder, and is a value used by the conversion unit 28 described later. Here, the calibration value 333 is a value output by the motion recorder when the acceleration components in the three-axis directions of the X, Y, and Z axes in the three-dimensional space are zero.

  The sensor coefficient 334 is a coefficient specific to the motion recorder and is a value used by the conversion unit 28 described later. Here, the sensor coefficient 334 is a change amount of each acceleration component in the three-axis directions of the X, Y, and Z axes in the three-dimensional space when the output value of the motion recorder changes by one. That is, the sensor coefficient 334 is a change amount of the acceleration component per unit change of the output value.

  The input unit 4 is a mouse or a keyboard, for example, and receives input from the user. Specifically, the user uses the input unit 4 to measure the time range of measurement data to be displayed on the display unit 5 (hereinafter simply referred to as a display time range) and the number of data as display accuracy (hereinafter simply displayed). Enter the component (specific data) you want to display. That is, the input unit 4 functions as a time range setting unit, a display accuracy setting unit, and a changing unit.

The display unit 5 is an LCD (Liquid Crystal Display), for example, and displays various types of information under the control of the display control unit 23 described later.
The CPU 2 is a processing device that performs various calculations and controls by executing application programs stored in an internal storage device (not shown) or an external storage device (not shown) of the information processing apparatus 1, thereby realizing various functions. .

FIG. 3 is a diagram illustrating a functional configuration of the CPU 2 according to the first embodiment. By executing the application program, the CPU 2 executes the first acquisition unit 20, the second acquisition unit 21, the determination unit 22, the display control unit 23, the reading interval calculation unit 24, the composite value calculation unit 25, the connection unit 26, and the data. It functions as a position detector 27 and a converter 28.
The first acquisition unit 20 acquires the measurement data folder 31 from the storage device in which the measurement data folder 31 in the motion recorder is stored, and records it in the storage unit 3. That is, the first acquisition unit 21 stores the measurement data folder 31 in the storage unit 3.

The second acquisition unit 21 acquires measurement data from the data file 32 based on the read interval calculated by the calculation unit 24 described later (processed specific data). That is, the second acquisition unit 21 functions as a reading unit.
When there are a plurality of data files 32, the second acquisition unit 21 acquires the measurement data from the data file 32 that is determined by the data position determination unit 27 described later that the measurement data to be acquired exists. .

For example, the determination unit 22 determines whether or not measurement data exists in the measurement data folder 31 designated by the user using the input unit 4.
Specifically, the determination unit 22 compares the measurement start time 331 of the header file 33 included in the measurement data folder 31 specified by the user with the date included in the file name of the data file 32. Further, along with this comparison, the determination unit 22 compares the start file information 332 of the header file 33 included in the measurement data folder 31 with the file connection information included in the file name of the data file 32. If these comparison results match, the determination unit 22 calculates the total number of measurement data included in the data file 32 in which the file connection information is continuous based on the file connection information. If the calculation result is greater than 0, the determination unit 22 determines that valid data exists in the measurement data folder 31.

The display control unit 23 functions as a display control unit that displays various types of information such as time-series data on the display unit 5 by controlling the display state of the display unit 5.
The reading interval calculation unit 24 calculates an interval for reading measurement data from the data file 32 based on the display time range and the display data number as display accuracy specified by the user using the input unit 4.

More specifically, the reading interval calculation unit 24 calculates the reading interval of measurement data based on the following equations (1) and (2). That is, the read interval calculation unit 24 functions as a read interval determination unit.
Read interval ≒ Display interval ÷ Measurement cycle (1)
Display interval ≒ Display time range ÷ Number of display data (2)
Here, the measurement cycle is a cycle in which the motion recorder measures information such as acceleration.

When the reading interval or the display interval includes a numerical value after the decimal point, the decimal point may be rounded up or down.
The synthesized value calculation unit 25 calculates a value obtained by synthesizing at least two pieces of information (two specific data) among information such as acceleration in three axis directions measured by the motion recorder in response to an instruction from the input unit 4. Specifically, based on the read interval calculated by the read interval calculation unit 24, at least 2 of the information such as acceleration in the three-axis direction acquired by the second acquisition unit 21 and converted by the conversion unit 28 described later. A value (combined processed 2 specific data) obtained by combining the above information (processed 2 specified data) is calculated. That is, the composite value calculation unit 25 performs a distance composition process. For example, when the value r obtained by combining the acceleration information of the X, Y, and Z axes is calculated, the combined value r is calculated based on the following equation (3). That is, the composite value calculation unit 25 functions as a combining unit.

In the equation (3), X, Y, and Z are accelerations in the X, Y, and Z axis directions converted by the conversion unit 28 described later.
The connection unit 26 connects the measurement data acquired by the second acquisition unit 21 from the data file 32 and the composite value r calculated by the composite value calculation unit 25 based on the read interval calculated by the read interval calculation unit 24. . Specifically, the measurement data obtained by the second acquisition unit 21 converted by the conversion unit 28 to be described later and the composite value r calculated by the composite value calculation unit 25 are interpolated to obtain measurement data. To create time series data.
Here, the interpolation processing is, for example, linear interpolation. The connecting unit 26 can also use various interpolation methods such as spline interpolation, Bezier interpolation, and Lagrange interpolation.

When a plurality of data files 32 are created by the motion recorder, the data position determination unit 27 determines in which data file 32 the measurement data to be acquired exists.
Specifically, which data file 32 the second acquisition unit 21 acquires based on the number of points of measurement data recorded in one data file 32 and the read interval calculated by the read interval calculation unit 24. It is determined whether there is power measurement data.

The conversion unit 28 converts the measurement data acquired from the data file 32 by the second acquisition unit 21 based on the calibration value 333 and the sensor coefficient 334 included in the header file 33 according to the following equation (4). To do.
Measurement data after conversion = [(measurement data)-(calibration value)] x sensor coefficient
... (4)
The operation of the information processing apparatus 1 according to the first embodiment configured as described above will be described with reference to the flowchart (steps A1 and A2) shown in FIG.

  After the first acquisition unit 20 stores one or more measurement data folders 31 created by the motion recorder in the storage unit 3 (storage step), the user designates the measurement data folder 31 using the input unit 4 (step A1). ). Next, the 2nd acquisition part 21 acquires measurement data from the data file 32 of the measurement data folder 31 designated by the user, and the display control part 23 displays the time series data on the display part 5 (step A2).

Next, details of the step of designating the measurement data folder 31, that is, the detailed operation of step A1 in FIG. 4 will be described with reference to the flowchart (steps A11 to A14) shown in FIG.
First, the user designates the measurement data folder 31 stored in the storage unit 3 using the input unit 4 (step A11). Next, the determination unit 22 determines whether or not measurement data exists in the specified measurement data folder 31 (step A12). When measurement data exists in the designated measurement data folder 31 (see the Yes route in step A12), the second acquisition unit 21 acquires the measurement start time 331 included in the header file 33, and the display control unit 23 By displaying the measurement start time 331 on the display unit 5, the display unit 5 displays the time indicated by the measurement start time 331 (step A13). Furthermore, the user designates the time indicated by the measurement start time 331 displayed on the display unit 5 (step A14).

If it is determined in step A12 that the measurement data does not exist in the designated measurement data folder 31 (see No route in step A12), the display control unit 23 displays that the measurement data does not exist. 5, the user is prompted to specify another measurement data folder 31.
Next, details of the step of displaying time-series data, that is, detailed operations of step A2 in FIG. 4 will be described with reference to the flowchart (steps A21 to A26) shown in FIG.

  First, the user uses the input unit 4 to synthesize information such as acceleration in the X, Y, and Z axis directions displayed on the display unit 5 and at least two pieces of information such as acceleration. Among the values r, at least one data component is designated as specific data (step A21). Next, the user designates a display time range using the input unit 4 (step A22). In the initial state, it can be considered that all the time ranges related to the data file 32 included in the measurement data folder 31 selected by the user are automatically designated as the display time range. Furthermore, the user designates the number of display data as display accuracy using the input unit 4 (step A23).

  Next, the reading interval calculation unit 24 calculates a data reading interval based on the designated display time range and the number of display data (step A24; reading interval determination step). The second acquisition unit 21 acquires measurement data of the component selected in step A21 from the data file 32 based on the read interval calculated by the read interval calculation unit 24. When the composite value r is selected in step A21, the second acquisition unit 21 extracts the X, Y, and Z components from the data file 32 based on the reading interval calculated by the reading interval calculation unit 24. Among them, measurement data of at least two components is acquired and converted by the conversion unit 28, and then the composite value r is calculated by the composite value calculation unit 25. Next, the connecting unit 26 creates time-series data by connecting the measurement data acquired by the second acquiring unit 21 or the synthesized value r calculated by the synthesized value calculating unit 25 (step A25). . And the display control part 23 displays the time series data produced by the connection part 26 on the display part 5 (step A26). A specific display example will be described later with reference to FIGS.

In addition, when the operation of step A21 is performed in the state where the time series data is displayed on the display unit 5, the processes of steps A24 to A26 are performed again, for example, for the component newly added in step A21. Time series data is displayed.
Further, when the operation of step A22 is performed in a state where the time series data is displayed on the display unit 5, the processing of steps A24 to A26 is performed again, and the measurement data read interval newly calculated in step A24 is set. Based on this, time-series data is displayed.

Further, when the operation of step A23 is performed in the state where the time series data is displayed on the display unit 5, the processing of steps A24 to A26 is performed again, and a new operation is performed in step A24 using the changed number of display data. Time-series data is displayed based on the calculated measurement data read interval.
Next, details of steps for creating time-series data, that is, detailed operations of step A25 in FIG. 6 will be described with reference to a flowchart (steps A251 to A263) shown in FIG.

  First, the second acquisition unit 21 opens the data file 32 having file connection information that matches the start file information 332 described in the header file 33 (step A251). Next, the data position determination unit 27 determines whether or not there is measurement data to be read in the opened data file 32 (step A252). When the data to be read is in the currently open data file 32 (see the Yes route in step A253), the second acquisition unit 21 acquires measurement data (step A254; read step). Further, the measurement data acquired in step A254 is subjected to conversion by the above equation (4) in the conversion unit 28 (step A255), and the data converted in step A255 is obtained by the interpolation process performed by the connecting unit 26. , It is linked with other data that has already been converted (step A256). Thereafter, the determination unit 22 compares the number of data linked in step A256 with the number of display data specified by the user, and if the number of linked data is the same as the number of display data, creation of time-series data Is completed, and the measurement data connection process is terminated (see the Yes route in step A257). In step A257, when the determination unit 22 determines that the number of data connected in step A256 is less than the number of display data (see No route in step A257), the process returns to step A252 and is acquired. It is determined whether or not measurement data to be present exists in the currently open data folder (from No route of step A257 to step A252).

  On the other hand, when the measurement data to be acquired does not exist in the currently opened data folder 32 (see the No route in step A253) and the file connection information exists in the continuous data folder 32 (see the Yes route in step A258). The second acquisition unit 21 closes the currently opened data file 32 and opens the data file 32 with continuous file connection information. That is, the data file 32 is switched (step A259), and the measurement is performed from the switching destination data file 32. Data is acquired (step A254). Thereafter, the processes of steps A255 to A257 described above are performed.

  If the measurement data to be acquired does not exist in the data folder 32 having the file connection information subsequent to the file connection information of the currently opened data folder 32 (see No route in step A258), the measurement data to be acquired is The existing data file 32 is searched (step A260). Specifically, the data position determination unit 27 determines whether the measurement data to be acquired is based on the number of measurement data recorded in one data file 32 and the read interval calculated by the read interval calculation unit 24. By calculating the existing data folder 32, the data file 32 containing the measurement data to be acquired is searched. In other words, the read interval calculation unit 24 calculates the number of data files 32 to be skipped from the position in the data file 32 of the measurement data previously acquired by the second acquisition unit 21 and the number of data in one data file. . When the data position determination unit 27 finds the data file 32 in which the measurement data to be acquired exists (see the Yes route in step A261), the second acquisition unit 21 closes the currently open data file 32, The data file 32 found in step A260 is opened, that is, the data file 32 is switched (step A262), and the measurement data is acquired from the switching destination data file 32 (step A254). Thereafter, the processes of steps A255 to A257 described above are performed.

In step A260, when the data file 32 containing the measurement data to be acquired is not found (see No route in step A261), the creation of time series data is terminated at that point (step A263).
Next, an image displayed on the display unit 5 will be described.
8 and 9 are diagrams illustrating examples of images displayed on the display unit 5 in step A26.

  For example, in the display image 100 shown in FIG. 8, time series data of accelerations in the X, Y, and Z axis directions are displayed as specific data. In the display image 101 shown in FIG. 9, time series data of a combined value r of accelerations in the X, Y, and Z axis directions is displayed as specific data. The display images 100 and 101 each include a display data number selection unit A, a display range setting unit B, a display component setting unit C, a measurement start time display unit D, a display interval E, and a data display unit F.

  The display data number selection unit A is a display area for selecting the display size of the time series data, that is, the number of display data (display accuracy). In this display data number selection section A, various pulls of display data are displayed when the user pulls down using the input section 4. The user uses the input unit 4 to select one display data number as the display accuracy from among the various display data numbers displayed. Instead of selecting from the pull-down, the user can directly input the number of display data using the input unit 4. In the display data number selection unit A shown in FIGS. 8 and 9, 500 is selected as the display data number.

  The display range setting part B is a display area for setting a display range such as an enlargement / reduction function. The user can change the display range such as enlargement / reduction of the display range by operating the display in the display range setting unit B using the input unit 4. For example, after the user selects enlargement in the display range setting unit B, the user selects a waveform and display range to be enlarged and drags the desired region in the data display unit F, and changes the display range. Can do.

  Note that the user can also directly input the display range using the input unit 4. In addition, when the user directly inputs the display range using the input unit 4, the user may input two times to indicate the display range, or specify only the time of the start point or end point of the display range. May be. For example, when only the time of the start point of the display range is specified, the time range determined by the time of the start point specified by the user and the last time when data such as acceleration is measured by the motion recorder is specified. I reckon. For example, when only the end time of the display range is specified, a time range determined by the first time when data such as acceleration is measured by the motion recorder and the start time specified by the user is specified. It is considered to have been.

The display component setting unit C is a display area for selecting at least one of the X, Y, and Z axis components in the three-dimensional space and at least two combined components r of these three. In the display component setting unit C, when the user selects and sets a desired component using the input unit 4, time-series data regarding the selected component is displayed.
The measurement start time display part D is a display area for displaying the measurement start time 331 of the header file 33 included in the measurement data folder 31 selected by the user using the input part 4. When a plurality of measurement data folders 31 are read, a plurality of measurement start times 331 are displayed when the user pulls down using the input unit 4. Furthermore, when the user selects a desired measurement start time 331 using the input unit 4, time-series data for the selected measurement start time 331 is displayed.

The display interval E displays the reading interval calculated by the reading interval calculation unit 24, that is, the display interval.
The data display unit F is a display region for displaying time-series data generated according to the conditions selected by the display data number selection unit A, the display range setting unit B, the display component setting unit C, and the measurement start time display unit D. . Here, the data display unit D in FIG. 8 shows an example of displaying time-series data when the X, Y, and Z axis components are selected and set in the display component setting unit C, and the data display unit D in FIG. Shows an example of displaying time-series data when the composite component r is selected and set in the display component setting unit C.

  FIG. 10 is a diagram showing a display image 100 ′ when the main part of the display image 100 shown in FIG. 8 is enlarged by the user using the input unit 4. In the data display section F of the display image shown in FIG. 10, the rectangular area G designated by the display range setting section B in the data display section F of FIG. 8 is enlarged and displayed. At this time, since the readout interval calculation unit 24 newly calculates the readout interval based on the displayed time range, the display interval E in FIG. 10 changes compared to the display interval E in FIG. In the example of FIG. 9, since the image is enlarged, the value of the display interval E is small.

  As described above, according to the information processing apparatus 1 of the first embodiment, the reading interval calculation unit 24 calculates the reading interval based on the display time range and the number of display data, and the second acquisition is performed based on the reading interval. The unit 21 acquires the measurement data, and the connection unit 26 creates time series data based on the data acquired by the second acquisition unit 21 so that the measurement data is displayed on the display unit 5. When the amount of data recorded by a recorder or the like is large, the time required for displaying on the data display unit 5 can be greatly shortened.

  Further, according to the information processing apparatus 1 of the first embodiment, since the measurement data is acquired from the plurality of data files 32 and the time series data is created, some data is generated due to a user operation or a recorder malfunction during measurement. Even when the file 32 is damaged or lost, not all measurement data is available, and time series data can be partially created using valid measurement data and displayed on the display unit 5. Furthermore, the processing time required for creating time-series data can be further shortened by distributing a plurality of data files 32 to a plurality of CPUs 2.

[B] Description of Modified Example of First Embodiment FIG. 11 is a diagram illustrating a functional configuration of the CPU 2 of a modified example of the first embodiment. The CPU 2 in this modification example executes an application program stored in an internal storage device or an external storage device of the information processing apparatus 1 (not shown), thereby adding the function of the CPU 2 of the first embodiment, the trajectory information generation unit 41, It functions as an attitude information generation unit 42, a marker file determination unit 43, and an addition unit 44. Since the same reference numerals as those already described indicate the same or substantially the same parts, the description thereof is omitted.

In this modification, the user uses the input unit 4 to specify an integration rank for acceleration measured by the motion recorder and a viewpoint in a trajectory map described later.
The trajectory information generation unit 41 generates trajectory information based on the integration rank and viewpoint input from the input unit 4 and the time-series data displayed on the display unit 5 when the user requests display of the trajectory map. That is, the trajectory information generation unit 41 generates trajectory information based on the integration rank, viewpoint, and time series data generated by the connection unit 26 input from the input unit 4. In other words, the trajectory information generation unit 41 performs a Lissajous synthesis process. For example, when the user uses the input unit 4 to select a viewpoint from the front of the measurement target, that is, a plane formed from the X-axis direction and the Y-axis direction in the tertiary space, the trajectory information generation unit 41 Generates trajectory information based on time-series data in the X-axis direction and the Y-axis direction. Further, for example, when the user instructs to perform first-order integration using the input unit 4, after integrating the time series data, the trajectory information is obtained based on the time series data after integration. Generate.

Further, the trajectory information generation unit 41 uses, for example, the data file included in the measurement data folder 31 selected by the user, from the time series data included in the time range specified by the user using the input unit 4. The trajectory information is generated so that the trajectory information is displayed in a format different from the trajectory information generated from the time-series data in the entire time range 32.
Further, the trajectory information generation unit 41 reads the time series data according to the time change in the time series data, and calculates the trajectory information based on the read time series data, thereby displaying the change in the trajectory information according to the time change. 5 can also be displayed. That is, the change of the trajectory information according to the time change can be displayed on the display unit 5 as a moving image. In this video, the data point on the orbit corresponding to the time in the specified time-series data is highlighted, and the point to be highlighted by changing the specified time by the user's operation using the input unit 4 is displayed on the orbit. Moving. In addition, the trajectory information generation unit 41 can move the point to be highlighted on the trajectory by repeating the process of changing the designated time after a predetermined time has elapsed.

The trajectory information generation unit 41 can be realized using various known methods, and detailed description thereof is omitted.
The display control unit 23 displays the trajectory information generated by the trajectory information generation unit 41 on the display unit 5 as a trajectory (Lissajous) image. For example, the display unit 5 includes all the trajectory information generated from the time series data included in the time range specified by the user using the input unit 4 according to the data file 32 included in the measurement data folder 31 selected by the user. Is displayed in a color different from the orbit information generated from the time-series data in the time range.

  When the user requests to display the posture information indicating the posture of the measurement target, the posture information generation unit 42 is based on the integration rank input from the input unit 4 and the time series data displayed on the display unit 5. Attitude information is generated. That is, the posture information generation unit 42 generates posture information based on the integration rank, viewpoint, and time series data generated by the connection unit 26 input from the input unit 4. For example, for example, when the user instructs to perform first-order integration using the input unit 4, after integrating the time series data, the posture information is obtained based on the time series data after integration. Generate.

  In addition, the posture information generation unit 42 reads the time series data according to the time change in the time series data, and calculates the posture information based on the read time series data, thereby displaying the change of the posture information according to the time change. 5 can also be displayed. That is, a change in posture information corresponding to a change in time can be displayed on the display unit 5 as a moving image. That is, the posture information generation unit 42 functions as an image data generation unit and a moving image processing unit. In this moving image, the time in the time series data for displaying the posture information can be changed by a user operation using the input unit 4. In addition, the posture information generation unit 42 can repeat the process of changing the designated time after a predetermined time has elapsed.

The posture information generation unit 42 can be realized by using various known methods, and detailed description thereof is omitted.
Further, the display control unit 23 causes the display unit 5 to display the posture information generated by the posture information generation unit 42 as an image indicating the posture of the measurement target (hereinafter sometimes simply referred to as a posture image).

  When the user requests display of information in the marker file, the marker file determination unit 43 determines the consistency between the marker file and the time series data generated by the connection unit 26. Here, the marker file is a file in which specific information calculated based on the acceleration in the X, Y, and Z axis directions measured by the motion recorder is recorded. For example, in the marker file, information indicating an interval at which a measurement target, which is a human, steps on one foot during walking, is recorded based on accelerations in the X, Y, and Z axis directions measured by a motion recorder. The information indicating the interval at which the object to be measured steps on one foot during walking is expressed, for example, by recording time information at the moment when one foot is stepped on in time series. Note that the interval at which one foot is depressed during walking can be determined, for example, by detecting the measured acceleration peaks in the X, Y, and Z axis directions.

The marker file may be created by the CPU 2 provided in the information processing apparatus 1 or may be created by another information processing apparatus (not shown), and the created marker file is a record accessible by the first acquisition unit 20. It is recorded on the medium.
The file name of the created marker file includes, for example, the date when the measurement of acceleration in the X, Y, and Z-axis directions used for creating the marker file is started. For example, when a marker file is created on May 8, 2010 using accelerations in the X, Y, and Z axis directions measured by a motion recorder, the file name of the marker file is, for example, “100508”. The file name of the marker file is not limited to this.

The marker file determination unit 43 determines whether the date of the file name of the marker file matches the measurement start date related to the currently displayed time-series data. The measurement start date related to the currently displayed time series data can be grasped, for example, by the marker file determination unit 43 referring to the header file 33 related to the currently displayed time series data.
When the determination unit 43 has matched the marker file with the time-series data generated by the connecting unit 26, the adding unit 44 connects the information for displaying the mark based on the information of the marker file. The time series data created by the unit 26 is added.

  More specifically, the adding unit 44 compares the time information described in the marker file with the measurement time of the measurement data read out by the second acquisition unit 21 and displayed on the display unit 5, In the case of coincidence, information for displaying a mark (hereinafter sometimes referred to as a first mark display) is added to the information for displaying the measurement data at the coincident time. Further, when the measurement data having the measurement time that matches the time information described in the marker file is not displayed, that is, when the comparison result does not match, the adding unit 44 is described in the marker file. Information for displaying mark data in a format different from the first mark display (hereinafter sometimes referred to as second mark display) is added to the information for displaying the measurement data closest to the current time information.

Here, the display control unit 23 causes the display unit 5 to display the time series data to which the information for performing the mark display is added, so that the display unit 5 displays the time series data with the mark display. Is done.
For example, for the time series data of the composite component r, the display control unit 23 is used in any case regardless of whether the measurement data at the measurement time that matches the time information described in the marker file is displayed. However, a mark display is superimposed on the displayed measurement data and displayed on the display unit 5. Therefore, the second mark display may be displayed as a different value or time depending on the extraction interval (display interval).

Here, the operation when the information processing apparatus 1 of the present modification configured as described above displays a trajectory will be described with reference to the flowchart (step A2, steps A31 to A35) shown in FIG.

In addition, the user designates a time range for displaying the trajectory information using the input unit 4 (step A33). The trajectory information generation unit 41 generates trajectory information based on the integration rank, the viewpoint of the trajectory map, and the time range specified by the user (step A34).

First, when the user requests display of marker file information in a state where the time-series data is displayed on the display unit 5 in the above-described step A2 (step A2), the input unit 4 is used, for example, the storage unit 3 The marker file stored in is designated (step A51). Next, the marker file determination unit 43 determines whether or not the date of the marker file name matches the measurement start date related to the currently displayed time series data (step A52). When the marker file determining unit 43 determines that there is consistency (see the Yes route in step A53), the adding unit 44 determines that there is consistency with the time-series data generated by the linking unit 26. Information for displaying a mark based on the marker file is added (step A54). Next, the display control unit 23 causes the data display unit F to display the time series data to which the information for displaying the mark is added by the adding unit 44 on the display unit 5 (step A55). When the marker file determination unit 43 determines that there is no consistency (see No route in step A53), the process of adding the marker file data to the time-series data is stopped. A specific display example will be described later with reference to FIG.

The display unit 54 is, for example, an LCD, and displays various types of information under the control of the display control unit 510.

The transmission / reception unit 56 transmits various information input by the user using the input unit 53 to the information processing apparatus 1 in accordance with the control of the transmission / reception control unit 511. Specifically, in addition to transmitting identification information and authentication information, the transmission / reception unit 56 receives information on the display time range, the number of display data, and the components such as the X, Y, and Z axes that are desired to be displayed. Transmit to device 1.
Further, the transmission / reception unit 56 receives the use permission notification transmitted by the transmission / reception unit 7 and the information generated by the connection unit 26, the trajectory information generation unit 41, the posture information generation unit 42, and the addition unit 44.

The operation of the network system 500 of the present embodiment configured as described above will be described with reference to the flowchart (steps A61 to A67) shown in FIG.
First, the transmission / reception unit 56 of the client device 50 transmits identification information and authentication information to the information processing device 1 (step A61). When the information processing apparatus 1 receives the identification information and the authentication information, the authentication unit 45 compares the authentication table included in the information processing apparatus 1 with the identification information and the authentication information received from the client apparatus 50, thereby the client apparatus 50. Is authenticated (step A62). If the authentication by the authentication unit 45 is successful (see the Yes route in step A62), the transmission / reception unit 7 transmits an authentication completion notification to the client device 50 (step A63). When the client device 50 receives the authentication completion notification, the transmission / reception unit 56 includes the measurement data folder 31 stored in the storage unit 52, the display time range, the number of display data, components such as X, Y, and Z axes to be displayed. Display conditions are transmitted (step A64). When the information processing apparatus 1 receives the measurement data folder 31 and the display conditions, and the measurement data folder 31 is stored in the storage unit 3 by the first acquisition unit 20, the processing in steps A24 and A25 as described above is performed. Time series data is created (step A65). The created time-series data is transmitted to the client device 50 by the transmission / reception unit 7 (step A66). When the client device 50 receives the time series data, the display control unit 510 displays the time series data on the display unit 54 (step A67). When the authentication by the authentication unit 45 fails (see No route in step A62), the transmission / reception unit 7 transmits a message to that effect to the client device 50 and causes the display unit 54 of the client device 50 to display the message. Thus, the transmission / reception unit 56 prompts the identification information and the authentication information to be transmitted again.

Thus, also in the network system 500 in the second embodiment, the same effect as the information processing apparatus 1 in the first embodiment can be obtained.
Further, according to the network system 500 in the second embodiment, when the user accesses the information processing apparatus 1 from the client apparatus 50 via the communication network 60 and enjoys the measurement data display processing service by the motion recorder, the identification is performed. Since the user authentication is performed based on the information and the authentication information, the administrator of the information processing apparatus 1 can provide a display processing service while ensuring security.

  Furthermore, according to the network system 500 in the second embodiment, since the client device 50 is connected to the information processing device 1 via the information network 60 such as the Internet, the user cannot directly operate the information processing device 1. The time required for displaying the information recorded by the motion recorder on a display device such as a display can be shortened.
