In particular, eyeglass-type electronic devices are suitable for transmitting major sensory information such as video and audio without interfering with daily activities, and are not available by incorporating various sensors and communication functions. Because application is expected, technological development is actively promoted in various fields. For example, Patent Document 1 below describes a line-of-sight detection device that measures the potential of a living body with electrodes provided at various locations of a spectacle frame and detects the direction of the line of sight from the measurement result.

JP 2011-126992 A

  In the method described in the above-mentioned patent document, it is necessary to detect a very weak bioelectric potential with high accuracy because the direction of the line of sight is detected by specifying the electrooculogram pattern from the bioelectric potential. Therefore, there is a problem that the device configuration is complicated and large.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide an eyeglass-type electronic device that can determine a state of a human body such as a state of eyelids or a line of sight with a simple configuration. .

An eyeglass-type electronic device according to the present invention includes at least one electrode provided on at least one of a lens and a frame, and a capacitance detection unit that generates a detection signal according to the capacitance between the electrode and the human body. And a human body state determination unit that determines the state of the human body including at least one of the eyelid state and the line of sight based on the detection signal.
According to the above configuration, since the state of the human body such as the state of the eyelid or the state of the line of sight is determined based on the detection signal corresponding to the capacitance between the electrode and the human body, the generation of the detection signal or the human body The state can be determined with a simple configuration.

Preferably, the human body state determination unit may compare the detection signal with a first threshold value and determine whether the eyelid is open based on the comparison result. Further, the human body state determination unit compares the detection signal with a second threshold value, and based on the comparison result, the eyelid is opened and the line of sight is facing front, or the eyelid is opened and the line of sight is You may determine whether you are not facing the front.
According to the above configuration, it is possible to determine the state of eyelids, the state of the line of sight, and the like with a simple process of comparing the detection signal with a threshold value.

Preferably, the glasses-type electronic device determines that the eyelid is open and the line of sight is facing the front when the eyelid is determined to be closed by the display unit that displays the image and the human body state determination unit. In at least one of the above cases, the display control unit may stop displaying video on the display unit.
According to the above configuration, since display of the video on the display unit is stopped in a state where the video on the display unit is not seen, such as a state where the eyelid is closed or a state where the line of sight is facing the front, Wasteful power consumption in the display unit is reduced. Further, when the line of sight is facing the front, the image by the display unit does not hinder the view.

Preferably, the spectacles-type electronic device may include two electrodes, and the capacitance detection unit may generate the detection signal corresponding to the capacitance between the two electrodes.
In this case, the human body state determination unit compares the detection signal with a first threshold value, and based on the comparison result, a capacitance between the two electrodes corresponds to the first threshold value. If it is larger than the capacitance value, it may be determined that the bag is open, and if it is smaller than the capacitance value, it may be determined that the bag is closed. The human body state determination unit compares the detection signal with a second threshold, and based on the comparison result, a capacitance between the two electrodes corresponds to the second threshold. If it is larger than the value, it may be determined that the line of sight is not facing the front, and if it is smaller than the capacitance value, it may be determined that the line of sight is facing the front.
According to said structure, based on the result of having detected the electrostatic capacitance between two electrodes, it becomes possible to determine the state of a eyelid, the state of a gaze, etc.

Preferably, the capacitance detection unit may generate the detection signal corresponding to a capacitance between one electrode and a human body.
In this case, the human body state determination unit compares the detection signal with a first threshold value, and based on the comparison result, the capacitance between the one electrode and the human body is the first threshold value. If it is larger than the capacitance value corresponding to the value, it is determined that the bag is closed, and if it is smaller than the capacitance value, it may be determined that the bag is open. The human body state determination unit compares the detection signal with a second threshold value, and based on the comparison result, a capacitance between the one electrode and the human body corresponds to the second threshold value. If it is larger than the capacity value to be determined, it may be determined that the line of sight is facing the front, and if it is smaller than the capacity value, it may be determined that the line of sight is not facing the front.
According to said structure, based on the result of having detected the electrostatic capacitance between one electrode and a human body, it becomes possible to determine the state of a eyelid, the state of a gaze, etc.

Preferably, the human body state determination unit may compare the detection signal with a third threshold value and determine whether or not the eyeglass-type electronic device is worn on the human body based on the comparison result. .
In this case, the eyeglass-type electronic device includes a power supply unit that supplies power to an electronic circuit including the capacitance detection unit and the human body state determination unit, and the eyeglass-type electronic device is attached to the human body in the human body state determination unit. When it is determined that the power is not supplied, the power is supplied to the electronic circuit from the power supply unit, and the electronic circuit shifts to a standby state in which the operation of some circuits is stopped. The human body state determination unit may further include a standby control unit that cancels the standby state when it is determined that the eyeglass-type electronic device is attached to the human body.
According to the above configuration, wasteful power consumption is reduced when the spectacles-type electronic device is not worn on the human body.

It is a figure for demonstrating the relationship between the electrostatic capacitance detected in the electrostatic capacitance detection part shown in FIG. 4, the state of a eyelid, and the state of a gaze.

Hereinafter, eyeglass electronic devices according to embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram illustrating the appearance of a spectacle-type electronic apparatus according to an embodiment of the invention. The eyeglass-type electronic device shown in FIG. 1 includes a front portion 1 located on the front surface (face) of the head, two temple portions 2 located on the side surface (the temple) of the head, and the front portion 1 and the temple portion. And two connecting portions 3 that connect the two in a foldable manner.

  The front unit 1 includes left and right eyeglass lenses 7, two rims 4 that hold the eyeglass lenses 7, and a bridge 5 that connects the two rims 4. The bridge 5 is formed of resin or the like, for example, and a circuit board 6 on which electronic circuit components such as a capacitance detection unit 20 and a processing unit 30 described later are mounted is accommodated in the bridge 5. In addition, a display unit 8 that displays an image in a part of the field of view is arranged in a part of the spectacle lens 7. The display unit 8 is a transmissive display using, for example, a half mirror.

FIG. 2 is a diagram illustrating an example of the configuration of the eyeglass-type electronic device illustrated in FIG.
For example, as shown in FIG. 2, the eyeglass-type electronic apparatus according to the present embodiment includes an electrode unit 10, a capacitance detection unit 20, a processing unit 30, a display unit 8, and a power supply unit 50.

  The power supply unit 50 supplies power to electronic circuits in the device including the capacitance detection unit 20, the processing unit 30, and the display unit 8.

  The electrode unit 10 includes one or a plurality of electrodes provided at positions where electrostatic coupling can occur between a human body close to the spectacle lens 7, particularly the eyelid or eyeball surface. This electrode is provided, for example, on the inner surface (human body side) of the eyeglass lens 7 or on the frame (such as the edge of the rim 4). When an electrode is provided on the inner surface of the spectacle lens 7, a transparent conductive film such as ITO (indium tin oxide), zinc oxide, or tin oxide is formed on the inner surface of the spectacle lens 7 by vapor deposition or the like.

  The capacitance detection unit 20 generates a detection signal Dc corresponding to the capacitance between the electrode of the electrode unit 10 and the human body. For example, the capacitance detection unit 20 applies a constant voltage between the electrode of the electrode unit 10 and the ground, or between the electrodes, and charges the charge accumulated in the capacitor charged by the constant voltage. It is converted into voltage by an amplifier.

  3 and 4 are diagrams illustrating an example of the configuration of the capacitance detection unit 20. FIG. 3 shows a configuration example of the capacitance detection unit 20 that detects the capacitance (mutual capacitance) between the electrodes when the electrode unit 10 has two electrodes 10A and 10B. FIG. 4 shows a configuration example of a capacitance detection unit 20 that detects a capacitance (self-capacitance) between the electrode 10C and a human body when the electrode unit 10 has one electrode 10C.

The capacitance detection unit 20 illustrated in FIG. 3 includes a drive unit 21, a charge amplifier unit 22, and an A / D conversion unit 23.
The drive unit 21 is a circuit that periodically supplies a drive voltage to the electrode 10A, and includes switches SW1 and SW2 in the example of FIG. The switch SW1 is connected between the electrode 10A and the power supply voltage VDD, and the switch SW2 is connected between the electrode 10A and the ground.
The charge amplifier unit 22 is a circuit that converts the electric charge accumulated in the capacitance between the electrodes 10A and 10B into a voltage. In the example of FIG. 3, the charge amplifier unit 22 includes an operational amplifier OP1, a capacitor Cx, and a switch SW5. The inverting input terminal of the operational amplifier OP1 is connected to the electrode 10B, and the non-inverting input terminal is connected to the ground. The capacitor Cx and the switch SW5 are connected in parallel between the output of the operational amplifier OP1 and the inverting input terminal.
The A / D conversion unit 23 converts the output voltage Sc of the charge amplifier unit 22 into a digital detection signal Dc.

  A capacitor Ce is formed between the electrode 10A and the electrode 10B, but when a human body exists in the vicinity thereof, parasitic capacitors Cb1 and Cb2 are also formed between the electrodes 10A and 10B and the human body, respectively. The The capacitor Ce decreases as the human body approaches the electrodes 10A and 10B. The capacitance detection unit 20 generates a detection signal Dc corresponding to the capacitance value of the capacitor Ce. Therefore, the capacitance value of the capacitor Ce indicated by the detection signal Dc of the capacitance detection unit 20 decreases as a part of the human body (eg, eyelid, eyeball) approaches the electrodes 10A and 10B (FIG. 5).

The capacitance detection unit 20 shown in FIG. 3 has a period during which the capacitor Ce is charged to a constant voltage (charging period), and a period during which the charge accumulated in the capacitor Ce is transferred to the charge amplifier unit 22 and converted into a voltage ( Charge transfer period) alternately.
That is, in the charging period, the switch SW1 is turned on, the switch SW2 is turned off, and the power supply voltage VDD is applied to the electrode 10A. Further, the switch SW5 is turned on during the charging period, the charge of the capacitor Cx is reset to zero, and the voltage of the electrode 10B becomes the ground level. Therefore, the voltage “VDD” is applied to the capacitor Ce during the charging period. The charge accumulated in the capacitor Ce during the charging period is proportional to the capacitance of the capacitor Ce because the voltage is a constant value “VDD”.
When the charge period shifts to the charge transfer period, the switch SW1 is turned off, the switch SW2 is turned on, and the voltage of the electrode 10A becomes the ground level. Further, the output voltage Sc of the operational amplifier OP1 is subjected to negative feedback control so that the switch SW5 is turned off and the voltage of the electrode 10B becomes the ground level during the charge transfer period. When the electrodes 10A and 10B are both at the ground level, the voltage of the capacitor Ce becomes zero, and all charges accumulated in the capacitor Ce during the charging period are transferred to the capacitor Cx. Since the output voltage Sc of the operational amplifier OP1 is substantially equal to the voltage of the capacitor Cx, it is proportional to the charge transferred from the capacitor Ce. Therefore, the output voltage Sc of the operational amplifier OP1 is a voltage proportional to the capacitance of the capacitor Ce. The detection signal Dc obtained by converting the output voltage Sc into a digital value is also proportional to the capacitance of the capacitor Ce.

On the other hand, the capacitance detection unit 20 shown in FIG. 4 includes a drive unit 21A, a switch SW4, a charge amplifier unit 22, and an A / D conversion unit 23.
The drive unit 21A is a circuit that periodically supplies a drive voltage to the electrode 10C, and includes a switch SW3 in the example of FIG. The switch SW3 is connected between the electrode 10C and the power supply voltage VDD. The switch SW4 is inserted into a path connecting the input of the charge amplifier unit 22 and the electrode 10C. The charge amplifier unit 22 and the A / D conversion unit 23 are the same as the components having the same reference numerals shown in FIG.

  A parasitic capacitor Cs is formed between the electrode 10C and the human body. The capacitor Cs increases as the human body approaches the electrode 10C. Therefore, in the case of the capacitance detection unit 20 shown in FIG. 4, the capacitance value of the capacitor Cs indicated by the detection signal Dc increases as a part of the human body (eg, eyelid, eyeball, etc.) approaches (FIG. 6).

Similarly to the capacitance detection unit 20 shown in FIG. 3, the capacitance detection unit 20 shown in FIG. 4 alternately repeats the charging period and the charge transfer period.
In the charging period, the switch SW3 is turned on, the switch SW4 is turned off, the power supply voltage VDD is applied to the electrode 10C, and the voltage “VDD” is applied to the capacitor Cs. In the charging period, the switch SW5 is turned on, and the charge of the capacitor Cx is reset to zero. The charge accumulated in the capacitor Cs during the charging period is proportional to the capacitance of the capacitor Cs because the voltage is a constant value “VDD”.
When the charge period shifts to the charge transfer period, the switch SW3 is turned off, the switch SW4 is turned on, the switch SW5 is turned off, and the output voltage Sc of the operational amplifier OP1 is subjected to negative feedback control so that the voltage of the electrode 10C becomes the ground level. When the electrode 10C becomes the ground level, the voltage of the capacitor Cs becomes zero, and all the charges accumulated in the capacitor Cs during the charging period are transferred to the capacitor Cx. Since the output voltage Sc of the operational amplifier OP1 is substantially equal to the voltage of the capacitor Cx, it is proportional to the charge transferred from the capacitor Cs. Therefore, the output voltage Sc of the operational amplifier OP1 is a voltage proportional to the capacitance of the capacitor Cs. The detection signal Dc obtained by converting the output voltage Sc into a digital value is also proportional to the capacitance of the capacitor Cs.
The above is the description of the capacitance detection unit 20.

Returning to FIG.
The processing unit 30 is a circuit that controls the overall operation of the eyeglass-type electronic device, and includes, for example, a computer (a CPU and a memory) that executes instructions based on a program stored in a storage device. . The processing unit 30 illustrated in the example of FIG. 2 includes a human body state determination unit 31, a display control unit 32, and a standby control unit 33 as processing blocks for realizing the predetermined function.

  Based on the detection signal Dc generated by the capacitance detection unit 20, the human body state determination unit 31 determines the state of the eyelid, the state of the line of sight, and the like as the state of the human body. Specifically, the human body state determination unit 31 compares the detection signal Dc with the first threshold value TH1, and determines whether the eyelid is open based on the comparison result. In addition, the human body state determination unit 31 compares the detection signal Dc with the second threshold value TH2, and based on the comparison result, the eyelid opens and the line of sight faces front, or the eyelid opens and the line of sight Determine whether is facing the front. Furthermore, the human body state determination unit 31 compares the detection signal Dc with the third threshold value TH3, and determines whether or not the eyeglass-type electronic device is worn on the human body based on the comparison result.

  The distance between the electrode (10A, 10B in FIG. 3 and 10C in FIG. 4) of the electrode unit 10 and the human body is the shortest when the heel is closed. When the eyelid is open, the distance between the electrode and the human body is the shortest when the line of sight is facing the front (when the convex part due to the cornea on the eyeball approaches the spectacle lens 7 side) (see FIG. 5, FIG. 6). Accordingly, the human body state determination unit 31 compares the detection signal Dc having a magnitude corresponding to the distance between the electrode and the human body with a predetermined threshold value (TH1, TH2), so that the electrode to the eyelid or the eyeball convex portion. By using the fact that the distances of the eyes are different, the state of the eyelid and the state of the line of sight are determined. Further, the human body state determination unit 31 compares the detection signal Dc with the threshold value TH3, and uses the fact that the electrode and the human body are remarkably separated when the spectacles type electronic device is not worn. It is determined whether or not it is attached.

  The display control unit 32 is a block that controls display of video on the display unit 8, and generates a video signal supplied to the display unit 8, for example. The display control unit 32 displays the video on the display unit 8 when the human body state determination unit 31 determines that the eyelid is closed or when it is determined that the eyelid is open and the line of sight is facing the front. To stop. The state where the eyelid is closed is a state where the image on the display unit 8 cannot be seen, and the state where the line of sight is facing the front is a state where a person other than the image on the display unit 8 is seen. In this state, it is unnecessary to display a video on the display unit 8. Accordingly, the display control unit 32 stops the video display on the display unit 8 in such a case, thereby reducing power consumption associated with the video display process. Further, the display control unit 32 stops the video display on the display unit 8 while the line of sight is facing the front, thereby preventing the video on the display unit 8 from obstructing the field of view.

  The display control unit 32 determines that the determination state is constant for a certain period of time when the human body state determination unit 31 determines that the eyelid is closed or when it is determined that the eyelid is open and the line of sight is facing the front. The display of video on the display unit 8 may be stopped on the condition that the above is continued. Thereby, flickering of the video due to frequent video display stop can be suppressed.

When the human body state determination unit 31 determines that the eyeglass-type electronic device is not worn on the human body, the standby control unit 33 reduces the power supplied from the power supply unit 50 to the electronic circuit in the device. A transition is made to a standby state in which the operation of some of the circuits is stopped. For example, the standby control unit 33 stops the circuit operation (display process) of the display unit 8 or reduces the frequency of the drive voltage pulse in the capacitance detection unit 20.
When the human body state determination unit 31 determines that the eyeglass-type electronic device is worn on the human body in the standby state, the standby control unit 33 cancels the standby state and resumes normal operation.

  Here, an operation for determining the eyelid state and the line-of-sight state in the eyeglass-type electronic apparatus according to the present embodiment having the above-described configuration will be described.

FIG. 5 is a diagram for explaining the relationship between the capacitance (mutual capacitance) of the capacitor Ce detected by the capacitance detection unit 20 shown in FIG. 3 and the state of eyelids and the state of line of sight. Periods T1, T3, and T4 indicate a state in which the bag 102 is opened, and a period T2 indicates a state in which the bag 102 is closed. Further, in a state where the eyelid 102 is opened, periods T1 and T3 indicate a state where the line of sight faces the front, and a period T4 indicates a state where the line of sight does not face the front (facing upward).
As shown in FIG. 5, during the period T2 when the heel 102 is closed, the heel 102 that is a part of the human body is closest to the electrodes 10A and 10B. The electric capacity is the smallest.
In the state in which the eyelid 102 is opened, the cornea convex portion 101 on the eyeball surface is closest to the electrodes 10A and 10B in the periods T1 and T3 when the line of sight is facing the front, so that the capacitance detection unit 20 detects the cornea. The capacitance of the capacitor Ce is the smallest.
When the eyelid 102 is opened and the line of sight deviates from the front direction, the capacitance of the capacitor Ce detected by the capacitance detection unit 20 is maximized.
Although not shown in FIG. 5, when the spectacles-type electronic device is not worn on the human body, the capacitance of the capacitor Ce detected by the capacitance detection unit 20 is further larger than the period T4.

  In FIG. 5, “C1” is the capacitance of the capacitor Ce corresponding to the first threshold TH1, and “C2” is the capacitance of the capacitor Ce corresponding to the second threshold TH2. The human body state determination unit 31 compares the detection signal Dc with the first threshold value TH1, and based on the comparison result, if the capacitance of the capacitor Ce is smaller than “C1”, the bag 102 is closed. If the capacitance of the capacitor Ce is larger than “C1”, it is determined that the bag 102 is open. Further, the human body state determination unit 31 compares the detection signal Dc with the second threshold value TH2, and based on the comparison result, if the capacitance of the capacitor Ce is smaller than “C2”, the line of sight indicates the front direction. If the capacitance of the capacitor Ce is larger than “C2”, it is determined that the line of sight is deviated from the front direction.

FIG. 6 is a diagram for explaining the relationship between the capacitance (self-capacitance) of the capacitor Cs detected by the capacitance detection unit 20 shown in FIG. 4, the eyelid state, and the line-of-sight state. The state of the eyelids and the state of the line of sight in the periods T1 to T4 in FIG. 6 are the same as those in FIG.
In the capacitance detection unit 20 shown in FIG. 4, contrary to the capacitance detection unit 20 shown in FIG. 3, the capacitance increases as the distance between the electrode 10 </ b> C and the human body becomes shorter. The capacitance of the capacitor Cs detected by the capacitance detection unit 20 during the period T2 is the largest.
In the state in which the eyelid 102 is opened, the capacitance of the capacitor Cs detected by the capacitance detection unit 20 becomes the largest during the periods T1 and T3 when the line of sight is facing the front.
When the eyelid 102 is opened and the line of sight deviates from the front direction, the capacitance of the capacitor Cs detected by the capacitance detection unit 20 is minimized.
Although not shown in FIG. 6, when the spectacles-type electronic device is not worn on the human body, the capacitance of the capacitor Cs detected by the capacitance detection unit 20 is further smaller than the period T4.

  In FIG. 6, “C1 ′” is the capacitance of the capacitor Cs corresponding to the first threshold TH1, and “C2 ′” is the capacitance of the capacitor Cs corresponding to the second threshold TH2. The human body state determination unit 31 compares the detection signal Dc with the first threshold value TH1, and based on the comparison result, if the capacitance of the capacitor Cs is greater than “C1 ′”, the bag 102 is closed. If the capacitance of the capacitor Cs is smaller than “C1 ′”, it is determined that the bag 102 is open. In addition, the human body state determination unit 31 compares the detection signal Dc with the second threshold value TH2, and based on the comparison result, if the capacitance of the capacitor Cs is greater than “C2 ′”, the line of sight is in the front direction. If the capacitance of the capacitor Cs is smaller than “C2 ′”, it is determined that the line of sight is deviated from the front direction.

  As described above, according to the eyeglass-type electronic device according to the present embodiment, based on the detection signal Dc corresponding to the capacitance between the electrode and the human body, the human body such as the eyelid state and the line of sight Since the state is determined, the generation of the detection signal Dc and the state of the human body can be realized with a simple configuration. Further, unlike the conventional method of detecting the line-of-sight direction based on the bioelectric potential, it is not necessary to bring a plurality of electrodes into contact with the human body, so that the user's uncomfortable feeling caused by using the electrodes can be reduced.

  In addition, according to the eyeglass-type electronic apparatus according to the present embodiment, since the state of eyelids and the state of the line of sight can be determined by comparing the detection signal Dc with the threshold value, the determination process can be simplified and the processing speed can be improved. The power consumption can be reduced by reducing the hardware processing load.

  Furthermore, according to the eyeglass-type electronic device according to the present embodiment, the image of the display unit 8 in a state where the image of the display unit 8 is not seen, such as a state where the eyelid is closed or a line of sight is not facing the front. Is stopped, wasteful power consumption in the display unit 8 can be reduced. Further, by stopping the video display when the line of sight is facing the front, it is possible to effectively prevent the video by the display unit 8 from obstructing the field of view.

Further, according to the eyeglass-type electronic device according to the present embodiment, when the human body state determination unit 31 determines that the eyeglass-type electronic device is not worn on the human body, the power is supplied from the power supply unit 50 to the electronic circuit in the device. The operation shifts to a standby state in which the operation of some circuits in the electronic circuit is stopped so that the power to be reduced. Therefore, it is possible to effectively reduce wasteful power consumption in a state where the eyeglass-type electronic device is not worn on the human body.
Moreover, when the human body state determination unit 31 determines that the eyeglass-type electronic device is attached to the human body during the standby state, the standby state is automatically canceled. Therefore, it is possible to immediately perform a normal operation without making the user aware of the standby state.

  As mentioned above, although several embodiment of this invention was described, this invention is not limited to embodiment mentioned above, Various modifications are included.

  In the above-described embodiment, an example of a spectacle-type electronic device is a device having a general spectacle shape, but the present invention is not limited to this. For example, the spectacle lens 7 can be omitted, and the shape of the frame is also arbitrary. Further, the present invention can be applied to, for example, a head mounted display attached to the head with a rubber band or the like.
