Japanese Unexamined Patent Publication No. 2014-166215

However, the above technique cannot increase the possibility that only highly accurate biometric information is generated or output. For example, in order to perform accurate pulse wave measurement, it is necessary to measure the pulse wave while the person to be measured is seated and stationary. Even if the hand to be measured moves, it greatly affects the measurement accuracy. The accuracy of the pulse wave information obtained while the hand to be measured or its thumb or the like is moving tends to be lower than the accuracy of the pulse wave information obtained when the hand is in a stationary state.

There is a need for technology that can generate or output only highly accurate biometric information.

On one side, a sensor provided in the housing of a mouse-type input device, which shines light on the hand of a user who uses the input device, and receives reflected light or transmitted light related to the light.
A biometric information measuring device is provided that includes a processor that generates biometric information of the user based on information related to an input operation in the input device and light receiving amount information obtained by the sensing unit.

According to the embodiment, a technique capable of generating or outputting only highly accurate biometric information is provided.

It is a figure which shows an example of the waveform of the biological information generated based on the received light amount information obtained in the state which there is an input operation with a mouse 5.

Hereinafter, each embodiment will be described in detail with reference to the accompanying drawings.

FIG. 1 is a diagram showing an example of a hardware configuration of the biological information measuring device 1 according to an embodiment. The information device 200 is also shown in FIG.

The biological information measuring device 1 includes a light emitting unit 20, a light receiving unit 30, and a control unit 170.

The light emitting unit 20 is provided in the sensor housing (not shown) and irradiates light to the outside through the optical window 11 (see FIG. 3) of the sensor housing. The light emitting unit 20 is formed by, for example, a Light-Emitting Diode (LED).

The light receiving unit 30 is provided in the same sensor housing (not shown) as the light emitting unit 20, and receives light through the optical window 11. The light emitting unit 20 is formed of, for example, two light-emitting diodes (LEDs) having different wavelengths.

The light receiving unit 30 is provided in the same sensor housing (not shown) as the light emitting unit 20 and receives light. The light receiving unit 30 is formed of, for example, a photodiode.

The light emitting unit 20, the light receiving unit 30, and the optical window 11 form a sensing unit 40 of the biological information measuring device 1.

The control unit 170 includes an interface 132, a memory 134, a timer 136, a Central Processing Unit (CPU) 138 (an example of a processing unit), and an Analog to Digital Converter (ADC) 140.

The drive circuit 110 and the amplifier circuit 120 are electrically connected to the control unit 170. Further, the power supply 130 is electrically connected to the control unit 170. Further, the wireless communication unit 142 is electrically connected to the control unit 170. The control unit 170 drives and controls the light emitting unit 20 via the drive circuit 110, processes the light receiving signal obtained via the light receiving unit 30 and the Analog to Digital Converter (ADC) 140, and generates biological information.

In this embodiment, as an example, the control unit 170 generates measured values related to pulse wave and hemoglobin as biological information based on the received light amount information obtained by the light receiving unit 30. For example, since the change in the amount of received light occurs in response to the change in the volume of the blood vessel, pulse wave information (volume pulse wave) can be obtained. In addition, since the change in the amount of received light occurs in response to the change in the concentration of hemoglobin in the bloodstream, it is possible to obtain a measured value related to hemoglobin. In this embodiment, as an example, the control unit 170 generates a pulse wave measurement value and a measurement value of ΔHb, which is an example of a measurement value related to hemoglobin. In this example, as an example, ΔHb has three kinds of values, that is, the concentration of oxyhemoglobin, the concentration of deoxyhemoglobin, the concentration of oxyhemoglobin, and the total concentration of deoxyhemoglobin.

The control unit 170 gives the generated biometric information to the wireless communication unit 142 via the interface 132. The wireless communication unit 142 transmits the biological information to the information device 200 via the antenna 144.

The wireless communication unit 142 receives a wireless signal from the information device 200 via the antenna 144. The wireless communication (data communication) via the antenna 144 may be based on, for example, Bluetooth (registered trademark). Further, in the modified example, the biometric information measuring device 1 may be electrically connected to the information device 200 by a wire such as Universal Serial Bus (USB).

An acceleration sensor 180 is electrically connected to the control unit 170. The acceleration sensor 180 detects the acceleration acting on the biological information measuring device 1. The acceleration sensor 180 detects, for example, acceleration in three orthogonal axes. The acceleration sensor 180 is provided, for example, in the sensor housing. However, in the modified example, the acceleration sensor 180 may be provided in the mouse 5 described later. In this case, the control unit 170 may acquire the acceleration information of the acceleration sensor 180 via, for example, the wireless communication unit 142, or the acceleration information of the acceleration sensor 180 via the information device 200 capable of communicating with the mouse 5 described later. May be obtained. Since the acceleration information represents the movement (acceleration) of the mouse 5 described later, it is a part of the operation information with the mouse 5 described later.

The information device 200 may be, for example, a user's personal computer (PC), a smartphone, a tablet terminal, or the like. The information device 200 has a display unit 201. In this embodiment, as an example, the information device 200 is a PC (PC with a display unit 201) capable of communicating with the mouse 5 described later. The communication between the mouse 5 and the information device 200 may be realized by wire or wirelessly. The information device 200 transmits the mouse information described later to the wireless communication unit 142.

FIG. 2 is a schematic view showing a mouse 5 to which the biological information measuring device 1 according to one embodiment is attached.

The mouse 5 is a mouse-type input device and has a housing 500. Mouse 5 generates mouse information. The mouse information is another part of the operation information on the mouse 5.

The housing 500 includes wheels 501. The wheel 501 can be rotated by the user and generates a part of mouse information. Further, the housing 500 includes an operation portion 502 on which the index finger is placed and an operation portion 503 on which the middle finger is placed when the user operates with the right hand. The operation site 502 and the operation site 503 can be pushed and operated, and generate a part of mouse information. Further, the mouse 5 includes a movement detection unit (not shown) that detects the movement of the housing 500. The principle of movement detection is not particularly limited. The movement detection unit may be, for example, an optical movement detection unit. The movement detector generates the other part of the mouse information.

While holding the housing 500, the user performs various input operations via the mouse 5 by moving the housing 500, pushing the operation portion 502 and the operation portion 503, and rotating the wheel 501. be able to.

As shown in FIG. 2, the biological information measuring device 1 is attached to the housing 500 of the mouse 5. The biometric information measuring device 1 may be detachably attached to the housing 500 or may be non-removably coupled. Further, the biological information measuring device 1 may be integrated with the mouse 5.

In the biological information measuring device 1, preferably, as shown in FIG. 2, the sensing unit 40 is arranged in a region of the housing 500 of the mouse 5 where the thumb of the operating user's hand touches. The sensing unit 40 is a part of the biological information measuring device 1. When the thumb of the user's hand operating the sensing unit 40 is touching, the biological information related to the thumb can be acquired via the sensing unit 40. Therefore, the biometric information measuring device 1 can measure the biometric information while the user holds the mouse 5 in his / her hand.

The sensing unit 40 is preferably provided along the surface of the housing 500. Alternatively, the sensing unit 40 is preferably provided so as to project from the surface of the housing 500 (see FIG. 3). In this case, there is a higher possibility that highly accurate biometric information can be obtained as compared with the case where the sensing unit 40 is provided inside (for example, in a recess) rather than the surface of the housing 500. Specifically, when the sensing unit 40 is provided inside the surface of the housing 500, the user tends to press a finger against the housing 500 in order to touch the sensing unit 40, and the reaction received from the housing 500. Blood flow can be affected if the force presses the finger more than necessary. On the other hand, when the sensing unit 40 is provided along the surface of the housing 500, or when the sensing unit 40 is provided so as to protrude from the surface of the housing 500, the finger touches the sensing unit 40. It is easy to realize the measurement in the state, and it is unlikely that the blood flow of the finger is affected by the reaction force received from the housing 500.

FIG. 3 is an explanatory view of the measurement operation of the biological information measuring device 1 provided in the housing 500 of the mouse 5, and is a cross-sectional view of the biological information measuring device 1 in a state where the surface of the finger (human body) of the person to be measured is in contact with the surface. It is a figure which shows roughly in. In FIG. 3, for the sake of explanation, the cross sections of the biological information measuring device 1 and the housing 500 are shown schematically. In the example shown in FIG. 3, the sensing unit 40 includes an optical window 11, a light emitting unit 20 adjacent to the optical window 11, and a light receiving unit 30. The optical window 11 is formed of a material having a high transmittance for measurement light.

At the time of measurement, a finger comes into contact with the sensing unit 40 of the biological information measuring device 1. When the light emitting unit 20 emits light to the outside in this contact state, a part of the light passes through the finger toward the light receiving unit 30 side as schematically shown by the arrow R1 in FIG. Then, a part of the light passing through the finger is incident on the light receiving unit 30. The light receiving unit 30 generates an electric signal (light receiving signal) according to the light receiving result. The light receiving signal from the light receiving unit 30 is processed by the control unit 170 to generate the above-mentioned biological information.

In this embodiment, the control unit 170 is a living body based on the operation information of the mouse 5 (an example of the operation information related to the input operation of the mouse 5) and the light receiving amount information (light receiving result) obtained by the sensing unit 40. Generate information. The operation information with the mouse 5 includes mouse information and acceleration information as described above. However, in the modified example, the operation information with the mouse 5 may be only one of the mouse information and the acceleration information.

Specifically, the control unit 170 suppresses the generation or output of biometric information in the state where the mouse 5 has an input operation, as compared with the state where there is no input operation, based on the operation information in the mouse 5. Suppressing the generation of biometric information is, for example, a mode in which the amount of biometric information generated in a state with an input operation is smaller than the amount of biometric information generated in a state without an input operation. Similarly, suppressing the output of biometric information is, for example, a mode in which the amount of biometric information output in a state with an input operation is smaller than the amount of biometric information output in a state without an input operation. In addition, suppressing the generation or output of biological information is a concept including not generating biological information and not outputting even if it is generated.

By the way, in order to perform accurate pulse wave measurement, it is necessary to measure in a state where the person to be measured is seated and stationary. Even if the hand to be measured moves, it greatly affects the measurement accuracy. The accuracy of biometric information obtained while the hand to be measured or its thumb or the like is moving tends to be lower than the accuracy of biometric information obtained when the hand is in a stationary state.

In this respect, in this embodiment, in the state where the mouse 5 has an input operation, the generation or output of biological information is suppressed as compared with the state where there is no input operation. Therefore, according to the biological information measuring device 1 of the present embodiment, the living body with higher accuracy is compared with the configuration in which the generation or output state of biological information is not changed between the state where the mouse 5 has an input operation and the state where there is no input operation. It is possible to increase the possibility that only information is generated or output.

Next, an operation example of the biological information measuring device 1 according to the present embodiment will be described with reference to FIGS. 4 and 5.

FIG. 4 is an explanatory diagram of the function of the biological information measuring device 1, and is a functional block diagram of the control unit 170.

The control unit 170 includes a light receiving amount information acquisition unit 172, an operation information acquisition unit 174, and a generation unit 176. The received light amount information acquisition unit 172, the operation information acquisition unit 174, and the generation unit 176 can be realized by the CPU 138 executing a program stored in the memory 134 or the like.

FIG. 5 is a flowchart for explaining an example of processing executed by the control unit 170 of the biological information measuring device 1. The process shown in FIG. 5 may be executed at predetermined intervals, for example, when the mouse 5 is touched by the user's hand. The state in which the user's hand touches the mouse 5 may be detected by, for example, an electrostatic sensor that may be provided on the mouse 5. Alternatively, the state in which the user's hand touches the mouse 5 may be detected when significant biological information is obtained based on the light receiving amount information from the light receiving unit 30.

In step S400, the operation information acquisition unit 174 acquires the operation information on the mouse 5, that is, the mouse information from the mouse 5 (or from the information device 200) and the acceleration information from the acceleration sensor 180.

In step S402, the light receiving amount information acquisition unit 172 acquires the light receiving amount information from the light receiving unit 30.

In step S404, the generation unit 176 determines whether or not there is an input operation in the mouse 5 based on the operation information and the acceleration information obtained in step S400. For example, the generation unit 176 determines that there is an input operation in the mouse 5 when there is mouse information or each component of acceleration is equal to or more than a predetermined threshold value. It should be noted that the fact that there is no input operation in the mouse 5 is substantially equivalent to the fact that the whole mouse 5 and a part of the mouse 5 are in a stationary state. If the determination result is "YES", the process proceeds to step S408, and if not, the process proceeds to step S406.

In step S406, the generation unit 176 associates the adopted flag "1" with the received light amount information obtained in step S402 within the current processing cycle. Corresponding to the adoption flag "1" means adopting the received light amount information. Adopting the received light amount information means using it for the calculation of the biological information described later. The received light amount information associated with the adoption flag "1" is stored in a predetermined memory area. In the predetermined memory area, for example, the received light amount information within the latest predetermined period ΔT is stored.

In step S408, the generation unit 176 associates the adopted flag "0" with the received light amount information obtained in step S402 within the current processing cycle. Corresponding to the adoption flag "0" means that the received light amount information is not adopted. Not adopting the received light amount information means that it is not used for the calculation of biological information described later. The received light amount information associated with the adoption flag "0" may be discarded. Further, when the adoption flag "0" is associated with the information, the information in the predetermined memory area may be reset.

In step S410, the generation unit 176 determines whether or not the condition for generating biological information is satisfied. The condition for generating biological information is satisfied, for example, when all the received light amount information within the latest predetermined period ΔT is associated with the adoption flag “1”. However, in the modified example, the condition for generating biological information may be satisfied, for example, when substantially all the received light amount information within the latest predetermined period ΔT is associated with the adoption flag “1”.

In step S412, the generation unit 176 generates biometric information within the latest predetermined period ΔT based on the received light amount information (time series waveform) in the predetermined memory area. At this time, the generation unit 176 may generate the biological information within the latest predetermined period ΔT by generating and storing the biological information at the time corresponding to the current cycle. That is, biological information at a time point other than the latest predetermined period ΔT may be generated at a corresponding time point in the processing cycle before this cycle. The biometric information is as described above.

In step S414, the generation unit 176 determines whether or not the output condition of the biological information is satisfied. The output condition of the biological information may be determined based on, for example, the pulse wave obtained in step S412 and each measured value of ΔHb. Specifically, other measurement conditions may be satisfied when there is no disturbance of the volume pulse wave. In this example, as an example, the other measurement conditions are that there is no disturbance of the volume pulse wave, the concentration of oxyhemoglobin (or the total value with the concentration of deoxyhemoglobin) is significantly higher than 0, and the concentration of oxyhemoglobin is high. It is established when the concentration and the concentration of deoxyhemoglobin are approximately equal. If the determination result is "YES", the process proceeds to step S416, and if not, the process proceeds to step S418.

In step S416, the generation unit 176 permits the output of the biometric information generated in step S410. Specifically, the generation unit 176 transmits (outputs) the biometric information generated in step S410 to the information device 200. At this time, the generation unit 176 may transmit all the biological information in the latest predetermined period ΔT to the information device 200, or may transmit only a part of the latest information to the information device 200. In this case, the information device 200 may output the biological information within the latest predetermined period ΔT to the display unit 201.

In step S418, the generation unit 176 prohibits the output of the biological information generated in step S410. Specifically, the generation unit 176 transmits alert information to the information device 200 instead of the biometric information generated in step S410. The alert information is information indicating that the generation of biological information is suppressed (stopped in FIG. 5). In this case, the information device 200 may output the alert information to the display unit 201. The output of the alert information may be accompanied by the output of a message such as "measurement is stopped".

In step S418, the generation unit 176 does not transmit the biometric information generated in step S412 to the information device 200. However, in the modified example, the generation unit 176 may transmit only the biometric information of the amount of data smaller than the amount of data (or the amount of information) transmitted in step S416 to the information device 200. For example, in step S416, in addition to the measured value of the pulse wave and the measured value of ΔHb, other biological information derived from the pulse wave and ΔHb (hereinafter, also referred to as “additional biological information”) is transmitted. On the other hand, in step S418, only the measured value of the pulse wave and the measured value of ΔHb may be transmitted. In this case, the additional biometric information may be, for example, pulse rate, blood pressure, index values related to the balance between oxyhemoglobin and deoxyhemoglobin (blood oxygen balance), and the like.

According to the process shown in FIG. 5, the light receiving amount information obtained in the state where the mouse 5 has an input operation is associated with the adoption flag "0" in step S408. The received light amount information associated with the adoption flag "0" is not used for generating biometric information (see step S412). Therefore, according to the process shown in FIG. 5, it is possible to increase the possibility that biometric information can be prevented from being generated based on the received light amount information obtained while the user's hand or his / her thumb is moving. .. As a result, according to the process shown in FIG. 5, it is possible to increase the possibility that only highly accurate biometric information is generated and output.

In the process shown in FIG. 5, step S414 may be omitted.

Further, in FIG. 5, the light receiving amount information obtained in the state where the mouse 5 has an input operation is associated with the adoption flag "0" in step S408, and the light receiving amount information associated with the adoption flag "0" is a living body. Not used to generate information. However, although the received light amount information associated with the adoption flag "0" is used for generating biometric information, the generated biometric information may not be output.

6 to 8 are an output example of the display unit 201 and explanatory views of the processing of FIG. FIG. 6 shows an example of the screen 800 on the display unit 201. FIG. 7 is a diagram showing an example of a waveform of biological information generated based on the received light amount information obtained when there is no input operation with the mouse 5. FIG. 8 is a diagram showing an example of a waveform of biological information generated based on the received light amount information obtained in a state where the mouse 5 has an input operation. 7 and 8 show a pulse wave waveform (time series waveform) 901 and each ΔHb waveform (time series waveform) 902 with the horizontal axis as time. Each of the ΔHb waveforms 902 includes a waveform 902A having a concentration of oxyhemoglobin, a waveform 902B having a concentration of deoxyhemoglobin, and a waveform 902C having a total value thereof.

The screen 800 includes a pulse wave information output area 801, a ΔHb information output area 802, and an alert information output area 803. The pulse wave information output region 801 outputs the pulse wave waveform 901 within the latest predetermined period ΔT. In the ΔHb information output region 802, each waveform 902 of ΔHb within the latest predetermined period ΔT is output. When the above-mentioned alert information is received by the information device 200, the alert information is output to the alert information output area 803. In the state where the alert information is output, the waveform may not be output to the pulse wave information output area 801 and the ΔHb information output area 802, or the waveform may not be updated even after a lapse of time. .. In the modified example, the above-mentioned additional biometric information may be output to the alert information output area 803 while the alert information is not received by the information device 200.

Here, when biometric information is generated based on the received light amount information obtained in the state where there is no input operation with the mouse 5, as shown in FIG. 7, a pulse wave waveform (time series waveform) with almost no disturbance is obtained. Be done. Further, the concentration of oxyhemoglobin (or the total value with the concentration of deoxyhemoglobin) is significantly higher than 0, and the concentration of oxyhemoglobin and the concentration of deoxyhemoglobin are substantially equal to each other.

On the other hand, when biological information is generated based on the received light amount information obtained in a state where the mouse 5 has an input operation, the waveform of the pulse wave may be disturbed as shown in FIG. Further, the concentration of oxyhemoglobin (or the total value with the concentration of deoxyhemoglobin) is significantly higher than 0, and the concentration of oxyhemoglobin is significantly higher than the concentration of deoxyhemoglobin. This is because the concentration of oxyhemoglobin tends to increase due to the movement of the user related to the input operation in the mouse 5. In this case, as described above, the accuracy tends to be lower than the biometric information obtained when there is no input operation with the mouse 5.
