Description

  The present invention relates to an exercise load amount presentation apparatus and method.

  When it is desired to change the stimulus presented from the wearing object, such as clothing having a cloth shape, for example, if it is a color stimulus, it is flexible as an organic EL (Electro Luminescence) panel (for example, see Non-Patent Document 1). There is a method of attaching a display or a minute LED (Light Emitting Diode) to a cloth-like member.

Kazumasa Nomoto, et al., “Development of Top-emission Flexible Organic EL Display” The Journal of the Institute of Image Information and Television Engineers Vol. 67, No.12, pp.1033 ~ 1037, 2013 Hashimoto, “Phosphorescent and temperature-sensitive discoloration fiber“ Saran Art (registered trademark) series ””, Textile and Industry, Vol. 66, No.9, pp.313-318, 2010

  However, the mounting target to which the organic EL panel or the like is attached has a disadvantage that the structure such as the organic EL panel or the LED is bulky and the cloth becomes thick. Moreover, there is an inconvenience that it is not possible to satisfy the requirement of being inexpensive and washable that is generally required for cloth-like clothing.

  From the viewpoint of eliminating this type of inconvenience, according to the inventor's study, as another method for changing the color stimulus presented from the wearing target, from a temperature-sensitive fiber (for example, see Non-Patent Document 2). A method of warming the temperature-sensitive cloth-like member with the heater is conceivable by the configuration in which the heater is wrapped with the cloth-like member. Although this method may be inexpensive and washable, for example, like an electric blanket, there is a disadvantage that the heater portion becomes thick. The inconvenience caused by the heater is not limited to color stimulation, and, for example, is similarly present in thermal stimulation.

  That is, according to the study of the present inventor, a technique for changing a stimulus presented from a wearing target such as clothing without using an organic EL panel, an LED, and a heater is desired. For example, the inventor conceivably uses such a technique for intuitively grasping the amount of exercise load from the cloth-like member worn by the user.

The parameter deriving unit 33 may set the normalized biological information feature A ′ as a parameter. The parameter deriving unit 33 may derive the thermal stimulation parameter Ps based on each normalized biological information feature A ′ when there are a plurality of normalized biological information features A ′. For example, when heart rate information A ₁ ′ and myoelectric information A ₂ ′ exist as normalized biological information feature A ′, the thermal stimulation parameter Ps may be derived based on the following equation.
Ps = w ₁ × A ₁ ′ + w ₂ × A ₂ ′

The output value deriving unit 34 may perform digital / analog conversion (hereinafter referred to as D / A conversion) on the derived voltage value and transmit the obtained voltage signal to the presentation unit 21 as an output signal.

  The output value deriving unit 34 may read the lookup table 100a from the storage unit 31, extract the voltage value E corresponding to the received value of the thermal stimulation parameter Ps from the lookup table 100a, and derive the voltage value. Note that the method of deriving the voltage value is not limited to the method of referring to the lookup table 100a, and any method such as applying a model equation that associates the thermal stimulation parameter Ps with the voltage value E is applicable.

  The measurement part 11 measures a user's biometric information via a 1st cloth-like member (ST101), and transmits the measurement signal according to the measured biometric information to the signal control part 30. The measurement unit 11 may measure the biological information of the user by causing the first cloth-like member to function as an electrode.

  The signal control unit 30 receives a measurement signal corresponding to the user's biological information, and derives an output value for presenting the user's exercise load based on the biological information. Specifically, as shown below, the biometric information feature amount extraction unit 32, the parameter derivation unit 33, and the output value derivation unit 34 execute steps ST102 to ST105.

The biometric information feature amount extraction unit 32 receives a measurement signal corresponding to the biometric information, and extracts the biometric information feature amount A of the biometric information (ST102). Specifically, the biometric information feature amount extraction unit 32 performs A / D conversion on the received measurement signal and extracts it as biometric information. The biometric information feature amount extraction unit 32 extracts the heart rate information A ₁ and the myoelectric information A ₂ as the biometric information feature amount A from the extracted biometric information, and transmits it to the parameter derivation unit 33.

  The output value deriving unit 34 performs D / A conversion on the derived voltage value E, and transmits a voltage signal corresponding to the voltage value E to the presentation unit 21 as an output signal.

  The presentation unit 21 outputs a voltage signal corresponding to the derived voltage value to the second cloth-like member and changes the temperature of the second cloth-like member, thereby causing the user to exercise load according to the temperature. The amount is presented (ST106). The presentation unit 21 may change the temperature of the second cloth-like member by causing the second cloth-like member to function as a resistor and present the exercise load amount to the user.

  As described above in detail, in one embodiment, the exercise load amount presentation device is equipped with a first cloth-like member and a second cloth-like member that are attached to a user and made of a conductive material. Present the amount. The exercise load amount presentation system measures the user's biological information through the first cloth-like member. Based on the measured user's biological information, an output value for presenting the user's exercise load is derived. An output signal corresponding to the derived output value is output to the second cloth-like member, and the temperature of the second cloth-like member is changed, so that the amount of exercise load is given to the user according to the temperature. To present.

Therefore, the user can perceive the amount of exercise load as a thermal stimulus from the attached cloth-like member. That is, it is possible to intuitively grasp the amount of exercise load from a cloth member (for example, a sports supporter) worn by the user. The first cloth member functions as an electrode. For this reason, a user can measure biometric information by wearing the first cloth-like member. Therefore, it is possible to measure the user's biometric information with a sports supporter that is less uncomfortable when worn by the user.

  The second cloth-like member generates heat by functioning as a resistor. For this reason, when the user wears the second cloth-like member, the temperature of the second cloth-like member can be changed and the amount of exercise load can be presented. Accordingly, it is possible to present the amount of exercise load to the user with a sports supporter that is less uncomfortable when worn by the user.

For this reason, it becomes possible to present an exercise load amount in consideration of the characteristics of changes in biological information caused by differences in exercise types. Therefore, it is possible to intuitively grasp the exercise load according to various exercise situations.

  In addition, according to the present embodiment, a cloth-like wearing target (eg, sports supporter) including a sensor unit (input device) and an output unit (actuator) can be realized.

  Further, by heating the cloth-like member made of a conductive material, the conventional configuration for wrapping the heater can be made unnecessary, and the user can be stimulated with a thin cloth.

(Description of modification)
In addition, the configuration and function of the exercise load amount presentation device, the communication procedure, the processing procedure, and the processing content can be variously modified and implemented without departing from the gist of the present invention.

  For example, the output unit 20 includes a second cloth-like member configured to soak a temperature indicating ink that changes color according to the temperature, and the presentation unit 21 includes the second cloth-like member according to the changed temperature. You may be comprised so that a color can be changed further.

  Such an embodiment can be realized without changing the thickness of the cloth, for example, by dyeing a cloth-like member using a highly hydrophilic functional material represented by “hitoe” with a temperature indicating ink. It is.

  In this case, the presentation unit 21 may receive an output signal corresponding to the output value from the signal control unit 30, and may receive a voltage signal corresponding to the voltage value as an output signal corresponding to the output value. The presentation unit 21 outputs the received output signal to the second cloth-like member and changes the color of the second cloth-like member to present the exercise load amount to the user according to the color.

  Moreover, the presentation part 21 may change the temperature of a 2nd cloth-like member by functioning a 2nd cloth-like member as a resistor, and may show an exercise load amount to a user.

  Note that the presentation unit 21 may change the color of the second cloth-like member in a single color, or may cause a different color to appear at each location of the second cloth-like member. . For example, the presentation unit 21 may color the second cloth-like member so as to have a striped pattern or a gradation.

Here, when the color is developed with a different color for each location of the second cloth-like member, for example, the presentation unit 21 includes a first output signal based on the heartbeat information A _1, the second based on the myoelectric information A ₂ The output signal may be output for each different region of the second cloth-like member. Further, different regions of the second cloth-like member may be formed by, for example, dyeing with a plurality of temperature indicating inks having different relationships between temperature and color. Moreover, you may form the different area | region of a 2nd cloth-like member by functioning the predetermined area | region of a 2nd cloth-like member as a resistor of a mutually different resistance value, for example. The first and second output signals may be output alternately or simultaneously in parallel. In this case, the signal control unit 30, for example, first first units 32 to 34 for transmitting the first output signal to the presentation unit 21 and a second for transmitting the second output signal to the presentation unit 21. The sections 32 to 34 may be provided.

  The storage unit 31 stores a lookup table 100c in advance as shown in FIG. In addition, the storage unit 31 includes biometric information corresponding to the measurement signal received from the measurement unit 11, the biometric information feature amount A extracted by the biometric information feature amount extraction unit 32, each value used for normalization, and a parameter derivation unit. The color stimulus parameter Pc derived by 33, the voltage value E derived by the output value deriving unit 34 as the output value, and the like may be stored.

  The lookup table 100c is table information stored in association with the color stimulus parameter Pc and the voltage value E. The look-up table 100c associates the hue angle H corresponding to the color stimulus parameter Pc with the color stimulus parameter Pc, associates the heat generation amount T corresponding to the hue angle H with the hue angle H, and further relates to the voltage corresponding to the heat generation amount T. By associating the value E with the calorific value T, the color stimulus parameter Pc and the voltage value E may be associated with each other.

  Here, the color stimulus parameter Pc is a parameter corresponding to the amount of exercise load to be presented to the user, and is an argument for deriving an output value for outputting a color to be presented to the user as the amount of exercise load. The hue angle H corresponds to the color stimulus parameter Pc and is a color change amount presented to the user as an exercise load amount. The calorific value T corresponds to the hue angle H, and an output signal corresponding to the output value is output to the second cloth-like member to change the color of the second cloth-like member. This is the amount of change in temperature necessary for the user to present the amount of exercise load. The voltage value E is an output value necessary for outputting the calorific value T.

  The hue angle H may correspond to a range of possible values (for example, 0 rad to 360 rad) with a range of possible values of the color stimulus parameter Pc (for example, 0 to 1). Further, the calorific value T may correspond to a range of possible values (for example, 0 ° C. to 2 ° C.) with a possible range of the value of the hue angle H. It should be noted that the correspondence between the voltage value E and the heat generation amount T (for example, a voltage value of 5 V is necessary to obtain a heat generation amount of 2 ° C.) and the correspondence relationship between the heat generation amount T and the hue angle H (for example, 360 rad In order to obtain a color change, a calorific value of 2 ° C. is required) may be derived by experiments carried out in advance.

  As the color stimulus parameter Pc, a plurality of color stimulus parameters Pc may be set for the second cloth-like member, and each color stimulus parameter Pc corresponds to color development of a part of the second cloth-like member. You may do it. Therefore, the parameter deriving unit 33 may read the lookup table 100c corresponding to each color stimulation parameter Pc from the storage unit 31 so that the output voltage value E corresponding to each color stimulation parameter Pc can be derived.

The parameter deriving unit 33 may derive or derive the color stimulus parameter Pc based on each normalized biometric information feature A ′ when there are a plurality of normalized biometric information features A ′. The color stimulus parameter Pc may be transmitted to the output value deriving unit 34. For example, when heart rate information A ₁ ′ and myoelectric information A ₂ ′ exist as normalized biological information feature A ′, the color stimulus parameter Pc may be derived based on the following formula.
Pc = w ₃ × A ₁ '+ w ₄ × A ₂ '
Here, w ₃ and w ₄ represent weights for the heart rate information A ₁ ′ and the myoelectric information A ₂ ′ when the color stimulus parameter Pc is derived, and are values that can be arbitrarily set. The weights w ₃ and w ₄ may be set to different values depending on the sport performed by the user wearing the exercise load amount presentation device 1. Further, the different weights w ₃ and w ₄ set for each sport are stored in advance in the storage unit 31 as a weight table 100b used in combination with the weights w ₁ and w ₂ , for example, as shown in FIG. Alternatively, a value different from the weight table 100b may be stored in the storage unit 31 in advance as a table different from the weight table 100b.

  The output value deriving unit 34 may receive the color stimulus parameter Pc from the parameter deriving unit 33 as a parameter corresponding to the exercise load, and derives a voltage value as an output value for presenting the user's exercise load. Also good. The output value deriving unit 34 may perform digital / analog conversion (hereinafter referred to as D / A conversion) on the derived voltage value and transmit the obtained voltage signal to the presentation unit 21.

  The output value deriving unit 34 may read the lookup table 100c from the storage unit 31, extract the voltage value E corresponding to the received value of the color stimulus parameter Pc from the lookup table 100c, and derive the voltage value. The method for deriving the voltage value is not limited to the method of referring to the lookup table 100c, and any method such as applying a model formula that associates the color stimulus parameter Pc with the voltage value E can be applied.

Next, an example of the operation | movement of the modification of the exercise load amount presentation apparatus comprised as mentioned above is demonstrated using the flowchart shown in FIG.4 and FIG.7. In the following description, the biological information, the heartbeat information A ₁ and myoelectric information A ₂ includes a biometric information feature amounts A, based on the heartbeat information A ₁ and myoelectric information A _2, the color stimulus parameter Pc The case of deriving will be described.

  First, the user wears the exercise load amount presentation device 1 including the first cloth-like member and the second cloth-like member made of a conductive material, and performs exercise. The second cloth-like member is constituted by soaking a temperature indicating ink that changes color according to temperature.

  The measurement part 11 measures a user's biometric information via a 1st cloth-like member (ST101), and transmits the measurement signal according to the measured biometric information to the signal control part 30. The measurement unit 11 may measure the biological information of the user by causing the first cloth-like member to function as an electrode.

  The signal control unit 30 receives a measurement signal corresponding to the user's biological information, and derives an output value for presenting the user's exercise load based on the biological information. Specifically, as shown below, the biometric information feature amount extraction unit 32, the parameter derivation unit 33, and the output value derivation unit 34 execute steps ST102 to ST105.

The biometric information feature amount extraction unit 32 receives a measurement signal corresponding to the biometric information, and extracts the biometric information feature amount A of the biometric information (ST102). Specifically, the biometric information feature amount extraction unit 32 performs A / D conversion on the received measurement signal and extracts it as biometric information. The biometric information feature amount extraction unit 32 extracts the heart rate information A ₁ and the myoelectric information A ₂ as the biometric information feature amount A from the extracted biometric information, and transmits it to the parameter derivation unit 33.

Parameter deriving section 33, a biometric information feature amounts A, receives the heartbeat information _{A 1} and myoelectric information _{A 2,} normalizes the heartbeat information _{A 1} and myoelectric information _{A 2} (ST103). Parameter deriving unit 33, based on the heartbeat information _{A 1} and myoelectric information _{A 2,} which is the normalized, to derive a color stimulus parameter Pc (ST 104). The parameter deriving unit 33 transmits the derived color stimulus parameter Pc to the output value deriving unit 34.

The output value deriving unit 34 receives the color stimulus parameter Pc from the parameter deriving unit 33, and reads the lookup table 100 c from the storage unit 31. The output value deriving unit 34 refers to the lookup table 100c and derives a voltage value E as an output value corresponding to the received color stimulus parameter Pc (ST105). Specifically, the output value deriving unit 34 refers to the lookup table 100c and derives the hue angle H corresponding to the color stimulus parameter Pc. Further, the output value deriving unit 34 refers to the lookup table 100c and derives the heat generation amount T corresponding to the derived hue angle H. The output value deriving unit 34 refers to the lookup table 100c and derives a voltage value E corresponding to the derived heat generation amount T.
The output value deriving unit 34 performs D / A conversion on the derived voltage value E, and transmits a voltage signal corresponding to the voltage value E to the presentation unit 21 as an output signal.

  The presentation unit 21 outputs a voltage signal corresponding to the derived voltage value to the second cloth-like member, and changes the temperature of the second cloth-like member. The presentation unit 21 further changes the color of the second cloth-like member according to the changed temperature, thereby presenting the exercise load amount to the user according to the color (ST106). In addition, the presentation part 21 may change the temperature of a 2nd cloth-like member by functioning a 2nd cloth-like member as a resistor, and may show an exercise load amount to a user.

  As described above, in this modification, the second cloth-like member is configured to be soaked with the temperature indicating ink that changes color according to the temperature.

  Thereby, when the second cloth-like member changes the temperature of the exercise load, the color of the second cloth-like member can be further changed to an arbitrary color according to the changed temperature. . Therefore, the user can more intuitively grasp the amount of exercise load from the worn cloth-like member.

  When the second cloth-like member is caused to function as a resistor, the second cloth-like member generates heat directly, and the temperature indicating ink soaked into the second cloth-like member changes its color in response to the heat. As a result, the amount of heat generation changes according to the magnitude of the current amount, and the color continuously changes accordingly. Therefore, unlike the prior art, a configuration in which the heat generation portion and the color development portion are the same portion is possible, and a loss in temperature transmission from the heat generation portion to the color development portion is small and a compact configuration can be achieved.
