50, display unit 116, operation unit 117, battery 164, amplifier unit 160, filter unit 16

1, includes a central processing unit (CPU) 162, a memory unit 163, and a constant voltage circuit 165.

The amplifier unit 160 includes a circuit for amplifying the electric signal output from the body motion detection sensor 150. The filter unit 161 includes a circuit for removing noise included in the amplified electric signal output from the amplifier unit 160. The CPU 162 uses the arithmetic circuit 162a that counts the amount of exercise such as the number of steps by performing various calculations using the electrical signal that is the body movement detection signal output from the filter unit 161, and the momentum calculated by the arithmetic circuit 162a. And a display circuit 162b that generates a display signal for display on the display unit 116. The CPU 162 issues a command to display various information such as measurement results on the display unit 116 using the display signal generated by the display circuit 162b. In addition, the CPU 162 executes a command input from the operation unit 117. The memory unit 163 stores programs for performing various arithmetic processes. Moreover, the target value mentioned later is memorize | stored. The battery 164 is a power source for supplying power to the CPU 162. The constant voltage circuit 165 is a circuit for stabilizing the power supply voltage supplied from the battery 164.

[0021] Pedometer 100, which is a force in the present embodiment, receives an input of a target value of the amount of exercise in advance, and displays a degree of achievement with respect to the set target value. Here, the amount of exercise refers to the number of steps calculated based on the detected body motion and various values calculated from the number of steps. Speed, walking pitch, exercise intensity, walking time, number of steps when walking at a certain level of exercise intensity, and walking time when walking at a level exceeding a certain level of exercise intensity. The user uses the operation unit 117 to input a target value for the amount of exercise to be displayed in advance. The target value can be set for each type of momentum. It is preferable that the force is configured to be S. In addition, it is preferable to be configured so that it can be set every day for the same type of momentum. These set values are stored in the memory unit 163 for each type of exercise amount and / or for each day.

FIG. 7 is a diagram showing a specific example of display in the pedometer 100 that is effective in the present embodiment. Referring to FIG. 7, on display unit 116, the number of steps, which is the amount of exercise, is displayed numerically as shown by display 116a. In addition, the degree of achievement of the number of steps, which is the amount of exercise, with respect to the set target value is displayed as a graph or segment group with the entire circumference as 100%, as shown in the display 116b. The graph shown in the display 116b shows the achievement level by the length of the graph with respect to the entire circumference or the central angle of the graph. Further, the time information that is information other than the amount of exercise is displayed by, for example, a numerical value as indicated by the display 116c.

FIG. 8 is a flowchart showing a process for displaying the calculated amount of exercise as shown in FIG. 7 in pedometer 100 according to the present embodiment. The processing shown in the flowchart of FIG. 8 is realized by the CPU 162 reading out the program stored in the memory unit 163, executing it by the arithmetic circuit 162a and the display circuit 162b, and controlling each unit shown in FIG.

Referring to FIG. 8, first, CPU 162 calculates an amount of exercise such as the number of steps based on the body motion detection signal input from body motion detection sensor 150 in arithmetic circuit 162a (step SD o where The calculation method is not limited to a specific method, and a calculation method performed by a normal pedometer can be adopted.

Next, the CPU 162 acquires a target value set corresponding to the amount of exercise to be displayed from the memory unit 163 (step S3), and inputs it to the arithmetic circuit 162a. In the arithmetic circuit 162a, using the momentum calculated in step S1 and the target value acquired in step S3, an achievement level that is a ratio of the above momentum to the target value is calculated (step S5) and displayed. Input to circuit 162b. In the display circuit 162b, processing for converting the achievement level input in step S5 into a graph length is performed (step S7), and the graph length is obtained. For example, when the achievement level is displayed in a circular graph as shown in FIG. 7, the display circuit 162b multiplies the total length of the graph by the achievement level calculated in step S5 above to obtain the length of the graph. Is calculated. Instead of the graph length, use the center angle. Good.

[0026] Then, in the display circuit 162b, a display signal for causing the display unit 116 to display a graph of the length (or angle) calculated in step S7 is generated (step S9).

[0027] The above processing is executed in the pedometer 100, which is effective in the present embodiment, so that the display unit 116 shown in FIG. 7 is based on the display signal generated in the step S9. Thus, the achievement level is displayed using a circular graph. By using a circular graph in this way, the achievement level can be recognized without displaying a scale. In addition, since no scale display is required, the display contents are not complicated, and the user can easily understand the display contents. In addition, by using a circular graph, it is possible to intuitively check the degree of achievement, such as that the degree of achievement is half of the target set or 1/4.

[Modification 1]

The shape of the graph is not limited to a circle as shown in FIG. 7, and may be a rectangle as shown in FIG. 9 or a polygon as shown in FIG. Good. In other words, the shape of the graph is not limited to a circle, but if it is an annulus with the start point and end point at the same position, the target value is the degree of achievement of the target value with the entire circumference as the target value (the length of the graph or the central angle) Can be displayed.

[0028] [Modification 2]

The number of objects to be displayed is not limited to one, and may be multiple types. Specifically, a plurality of types of momentum may be displayed. Or, when the memory unit 163 stores data on the amount of exercise for a predetermined period! /, The amount of exercise for a plurality of days may be displayed.

[0029] In that case, the display unit 117 displays a plurality of graphs with different distances from the center with the center as the same position. Specifically, when displaying the achievement level for each target value for three types of momentum, as shown in Fig. 11, a circular graph is displayed in three layers. In this case, it is possible to set in advance which momentum to display at which position. S Preferably, in step S7, the achievement calculated in step S5 is set to the length of the graph corresponding to the display position. It is preferable to convert.

[0030] By displaying in this way, even when a plurality of types of exercise amounts are displayed, the degree of achievement with respect to the target value can be confirmed at a glance. Therefore, multiple luck Even if you want to check the achievement level of the dynamic amount, you can check it on one screen without switching the display.

[0031] In addition, it becomes easy to compare the achievement levels for each amount of exercise. For example, when the amount of exercise to be displayed is the amount of exercise for a plurality of days, it becomes easy to compare the achievement levels of the above-mentioned multiple days.

[0032] Alternatively, when an indicator such as the achievement level of the previous day is displayed, the indicator may be displayed so as to overlap the display of the current achievement level, as indicated by display 116d in FIG. Good. In that case, it is preferable that the display mode of the above-mentioned indicator, such as the achievement level of the previous day, is different from the display mode of the current achievement level. More preferably, the display mode of the indicator blinks. And a different size (thickness).

[0033] As another specific example of the above-described index, when the pedometer 100 can set a plurality of target values for the exercise amount to be displayed, a plurality of set target values can be mentioned. As a specific display method, as shown in Fig. 12, it is superimposed on a circular graph that represents the degree of achievement of the maximum target value among the set target values, and other target values are used as indicators. You can also display it over the graph!

[0034] As yet another specific example of the index, when the pedometer 100 stores the amount of exercise for each user in the memory unit 163, the achievement level of other users can be mentioned. As a specific display method, the degree of achievement of other users may be used as an index, and the display may be superimposed on a circular graph representing the degree of achievement of the current user. In this case, from the viewpoint of comparison, the calculation value is stored in the memory unit 163 in the arithmetic circuit 162a so that the target value of the other user is the same as the target value of the current user. It is preferable to perform an operation that converts the achievement level of other users.

[0035] Thus, the user's willingness to achieve the goal is improved by being able to easily compare with indicators such as the achievement level of other days and the achievement level of other users.

[Modification 3]

The display direction on the display unit 116 may change according to the rotation of the pedometer 100.

[0037] In this case, the functional block of the pedometer 100 is shown in FIG. 6, as shown in FIG. In addition to each function, a position change detecting unit 166 for detecting a position change of the main body 110 with respect to the base 120 is included. Specifically, as shown in FIGS. 4 and 5, a microswitch 166a is provided on the front surface of the base portion 120, and is used as position change detection means. The micro switch 166a is configured to be pushed in the direction of arrow A in the figure by the back surface of the main body 110 when the main body 110 is in a non-rotating state!

FIG. 14 is a diagram illustrating a state in which the force is applied to the third modified example, and the pedometer 100 is rotated in a direction in which the main body portion is moved away from the base portion.

[0039] As shown in FIG. 14, the microswitch 166a protrudes forward by a predetermined distance (in the direction of arrow B in the figure) in the non-pressed state, and in this state, the microswitch 166a is in the off state. It is in. On the other hand, as described above, the microswitch 166a is pushed into the base portion 120 in the pushed down state, and in this state, the microswitch 166a is in the on state (see FIGS. 4 and 5).

As shown in FIG. 14, when the microswitch 166a is in a non-depressed state, the front surface of the main body 110 is directed upward by the rotation of the main body 110 with respect to the base 120. That is, the display unit 116 provided on the front surface of the main body unit 110 is exposed upward. Therefore, the user can visually recognize the display unit 116, and if the amount of exercise is displayed on the display unit 116, the user can visually recognize the display without removing the pedometer 100 from the clothes. Therefore, the display direction in this case is preferably the direction in which the user can visually recognize the display without removing the pedometer 100 from the clothes, that is, the direction shown in FIG.

[0041] On the other hand, as shown by a dotted line in FIG. 14, when the microswitch 166a is in the depressed state, the front surface of the main body 110 faces forward in the direction worn by the user. The display unit 116 provided on the front surface is exposed to the front in the wearing direction of the user and thus exposed. Therefore, a person other than the user can visually recognize the display unit 116. Therefore, the display direction in this case is preferably the direction in which the user can visually recognize the display from the front while wearing the pedometer 100 from the clothes, that is, the direction shown in FIG.

[0042] In the third modification, the detection signal is output from the microswitch 166a. The electrical signal is input to the CPU 162. The CPU 162 calculates the position of the main body 110 with respect to the base 120 based on this electrical signal. Based on the calculated position, the display direction on the display unit 116 is determined in the display circuit 162b. The CPU 162 uses the display signal generated by the display circuit 162b to issue a command to display various information such as measurement results on the display unit 116 so that the display circuit 162b displays in the direction determined.

[0043] The processing for performing the display in the third modification example is as follows. Referring to FIG. 16, after the processing in steps S1 to S9, CPU 162 is based on the detection signal from position change detection unit 166. Next, the position of the main body 110 with respect to the current base 120 is calculated (step S11). The display circuit 162b then determines the display direction according to the position calculated in step S11 (step S13).

[0044] It should be noted that the processing of step S11 and step S13 may be executed at any timing during the processing of steps S1 to S9, not necessarily after the processing of step S9.

[0045] The above processing is executed in the pedometer 100, which is effective in the present embodiment, so that the display signal generated in the step S9 and the display direction determined in the step S11 are used. In the display unit 116, as shown in FIG. 7 or FIG. 15, the achievement level is displayed in the orientation according to the current position of the main body unit 110 with respect to the base unit 120. Thus, the display direction is determined and displayed, so that the user can visually recognize the display without removing the pedometer 100 from the clothes. Alternatively, the user can view the display from the front with the pedometer 100 on the clothes.

[0046] The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
