  The swimming style information is information representing a swimming style such as a crawl style, a breaststroke style, a backstroke style, and a butterfly style.

  The swimming state information is information on the state of a swimmer who is swimming in each swimming method, and is information such as stroke pitch, number of strokes, stroke distance, swimming time, swimming distance, and hand position.

The stroke pitch is the number of strokes per unit time. For example, the number of strokes per second is calculated as a numerical value including a decimal point.
The number of strokes is the total number of strokes.
The stroke distance is a distance propelled by one stroke, and is calculated in units of meters, for example.
The time spent swimming is the total time spent swimming since the start of swimming.
The distance swam is the cumulative distance swam from the start of swimming.

The swimming information generation unit 37 refers to the swimming pattern table 50 and determines the swimming method from the tendency of the acceleration data and the gyro data included in the acquired activity information to generate the swimming method information. The acceleration data and gyro data included in the activity information are data detected by the acceleration sensor 17 or the gyro sensor 18 in the triaxial direction, and are data representing movements such as movement, tilt, and rotation of the swimmer's wrist WR. The swimming pattern table 50 is a table in which acceleration data in each axial direction, gyro data patterns, characteristics, feature points, and the like are stored in advance for each swimming method. The swimming information generation unit 37 compares the pattern, characteristics, and feature points of the input acceleration data and gyro data with the swimming pattern table 50, determines which swimming method is used, and generates swimming method information. Such determination of swimming style is also disclosed in, for example, a known document (US Patent No. US 8,652,010).

When the swimming information is determined (determined) from the activity information, the swimming information generation unit 37 derives the stroke pitch, the number of strokes, and the number of strokes from the activity information. Specifically, the number of strokes per unit time and the cumulative number of strokes are extracted by extracting frequency axis data from acceleration data and gyro data and counting the number of peaks of periodic data. Etc. are calculated.
The swimming time and the swimming distance are calculated from the time information T and the position information P that have passed since the swimming operation was started using the acceleration data or the gyro data and the position information data 43. Further, the stroke distance is calculated using the distance swam per unit time and the number of strokes between them.

  The swimming information generation unit 37 derives the hand position from the pressure data included in the activity information. When the pressure data indicates atmospheric pressure, the hand position is output on the water, and when the pressure data indicates water pressure, the hand position is output as water.

The locus generation unit 76 reads the map data 82 and the position information P, and draws (superimposes) the locus information on the map. Specifically, a map including the latitude and longitude positions of the position information P is acquired from the map data 82 and developed on a map layer that is a storage area for map image editing. The latitude and longitude of the position information P are read in time series from the position information table 85 based on the positioning time, and are drawn on the locus layer which is a storage area for locus image editing. Since the position information P is drawn at the position of latitude and longitude for each positioning time in the locus layer, it is drawn as a locus line. The map layer and the trajectory layer are matched to the scale on the map, the (latitude, longitude) coordinates of the position information P are made to correspond to the map, and the trajectory layer is overwritten and combined with the map layer to generate a trajectory information screen.

Switching and drawing the trace pattern of the locus line by the locus generation unit 76 according to the change of the swimming information S corresponds to generating an object according to the swimming information.

  An example of trajectory lines drawn in various modes generated by the trajectory generation unit 76 will be described with reference to the drawings. In addition, here, the aspect of the drawn locus line (trajectory information) will be mainly described, and detailed description of the illustrated example will be described later.

The trajectory lines shown on screen D50 (FIG. 15) and screen D55 (FIG. 16) are examples of different line types. Screen D50 shows the trajectory lines of a plurality of users (users UA, UB, and UC) as a plurality of swimmers, the trajectory LA is a solid line, the trajectory LB is a one-dot chain line, and the trajectory LC is a dotted line. It is drawn with different linetypes as possible. In the screen D55, for each lap (rap1, rap2, rap3), the locus Lrap1 is drawn with a solid line, the locus Lrap2 is a dotted line, and the locus Lrap3 is drawn with a one-dot chain line.

(Trace line shape / trajectory generator)
The trajectory L of the screen D10 and the screen D30 is drawn with a straight line between the measured data, whereas the trajectory L of the screen D40 is drawn with a curve. On screen D10 and screen D30, measurement points are drawn (not shown) in position information P where measured data exists, and a straight line is connected to each adjacent measurement point. For example, on the screen D10, the turning point of the locus L existing between the element E5 and the element E6 is the measurement point. Although not shown, a mark (such as a point different from the element mark) may be drawn so that the measurement point can be visually recognized.
On the screen D40, the locus L passing through the measurement point is drawn with a smooth curve.

(Band-shaped trajectory line / trajectory generator)
An example in which the band pattern on the band-shaped trajectory line is switched according to changes in the swimming information S and the like will be described with reference to FIGS. 10, 11, and 12. The locus L shown on the screen D20, the screen D23, and the screen D25 is an example in which the line width is widened and drawn in a band shape.

The trajectory L of the screen D20 (FIG. 10) has a belt shape, and the belt pattern is divided based on the change of the swimming style information included in the swimming information S. “Fly” of element E20 (halftone dot) indicates butterfly swimming, “Br” of element E21 (shaded line) indicates breaststroke, “Bc” of element E22 (white) indicates backstroke, element E23 (black) ) "F" indicates a crawl (freestyle) swimming style.
The length of the band in each element indicates that the swimming method is continued in the locus L.

The trajectory L of the screen D23 (FIG. 11) has a band shape, and the band pattern is segmented based on changes in pulse rate information included in the biological information B. As for the band pattern, the white pattern (displayed as “60”) has a pulse rate of less than 80 bpm (beats per minute), and the black pattern (displayed as “200”) has a pulse rate of 200 bpm or more. Is shown. In the meantime, the display “80” is 80 or more and less than 120, the display “120” is 120 or more and less than 160, the display “160” is 160 or more and less than 180, and the display “180” is 180 or more and less than 200 (both units are bpm). Each is shown, and the pattern is represented by gradually overcrowded oblique lines from rough oblique lines.
The length of the band in each element indicates that the pulse rate of the biological information B in the locus L is within the respective range. For example, in the element E41 and the element E44, the range of the pulse rate is 80 or more and less than 120. Further, from the element E44 to the element E47, the pulse rate gradually increases via the element E45 and the element E46. Thus, by drawing the information on the pulse rate as a band pattern, it is possible to easily identify the change in the load state of the swimmer during the swimming exercise.

The trajectory L of the screen D25 (FIG. 12) has a band shape, and the pattern of the band pattern is segmented based on a change in moving speed included in the position information P. In the band pattern, the white pattern (displayed as “0.5”) has a moving speed of less than 1.0 [m / sec], and the black paint pattern (displayed as “3.0”) is 3 This indicates that the moving speed is 0.0 [m / sec] or more. In the meantime, the display “1.0” is 1.0 or more and less than 1.5, the display “1.5” is 1.5 or more and less than 2.0, and the display “2.0” is 2.0 or more and less than 2.5. The display “2.5” indicates 2.5 or more and less than 3.0 (both units are m / sec), and the pattern is represented by slant lines with coarse intervals gradually from slant lines with coarse intervals.
The length of the band in each element indicates that the moving speed of the position information P is within the respective ranges in the locus L. For example, in the element E52, the moving speed is gradually increased from a speed of 1.0 or more and less than 1.5, and after passing through the elements E53 and E54, the element E55 swims at a speed of 2.5 or more and less than 3.0. It shows that it is out.

(Display screen generator / Display information generator)
The display screen generation unit 77 generates screen data in which information such as position information P, swimming information S, biological information B, and environment information En is further added (superimposed) to the generated trajectory information screen. Specifically, in order to explain such information, screen data is configured using marks, balloons, explanatory graphics, and the like. Note that marks, balloons, and explanatory graphics also correspond to objects included in the display information.

To do.

A screen D10 illustrated in FIG. 9 is an example in which a mark corresponding to the swimming style information of the swimming information S and the figure of the arrow Dir acquired from the position information P are drawn on the trajectory information screen.
On the screen D10, a round mark (element E1 to element E15) is drawn on the locus L. The marks are drawn on the locus L every predetermined elapsed time (for example, 1 second) from the element E1 to the element E15 in order. In the mark pattern of each element, the halftone dot is “Fly”, the oblique line is “Br”, the white is “Bc”, and the black is “F”.
An arrow Dir on the screen D10 represents a moving speed (including moving speed and moving direction). The moving speed is acquired from the position information P (position information table 85). The direction of the drawn arrow Dir indicates the moving direction, and the length of the arrow Dir indicates the moving speed.

  A screen D30 illustrated in FIG. 13 is an example in which a detailed description of each element is drawn by a balloon. A balloon (screen D30a) corresponding to the element E12 is drawn. The content of the swimming information S corresponding to the element E12 is drawn on the screen D30a. Specifically, the swimming method is “crawl swimming”, the STP (stroke pitch) is “40 times / min”, the STL (stroke length) is “1.05 m / time”, and the STC (number of strokes) is “2345 times”. Is drawn.

A screen D40 shown in FIG. 14 is an example in which analyzed information is drawn on the propulsive force and propulsion direction of a swimmer during swimming.
On the screen D40, an arrow TDV (Tide Vector) representing the tidal current speed, an arrow SFV (Swimming Force Vector) representing the swimmer's propulsion speed, and an arrow LV (Locus Vector) representing the moving speed on the trajectory are drawn. Further, in order to clearly show information in detail, the screen data is partially enlarged.
An arrow TDV (dotted arrow) is information acquired from the environment information En (environment information data 83) downloaded from the website 6 by the environment information acquisition unit 73, and is drawn on the sea surface portion of the map. The direction of the arrow TDV indicates the direction of the tidal current, and the length of the arrow TDV indicates the speed of the tidal current. The arrow TDV corresponds to tidal velocity information.
An arrow LV is the moving speed of the swimmer acquired from the position information P (position information table 85), and is drawn on the locus L.
The arrow SFV (propulsion speed) is calculated from the moving speed and the tidal current speed. Specifically, the propulsion speed is calculated by calculating the difference from the moving speed to the tidal speed by vector calculation. The propulsion speed indicates the direction and strength (speed) of the swimming exercise by the swimmer. That is, in the case where a tidal current is generated, the information is obtained by removing the influence of the tidal current from the actually moved state. The direction of the arrow SFV indicates the propulsion direction, and the length of the arrow SFV indicates the propulsion force (the propulsion speed). The arrow SFV corresponds to propulsion speed information.

A screen D50 illustrated in FIG. 15 is an example in which information on a plurality of users is drawn on one screen.
