2 is a diagram showing an embodiment of a wearable sensor as an embodiment of the present invention.

The wearable sensors 101, 102, 103, 104, and 105 of the present invention may be configured in a thimble shape as an embodiment to be inserted into a finger.

In addition, the wearable sensors 101, 102, 103, 104, and 105 of the present invention may be formed of a transparent material using a material using a transparent electrode and an insulator.

As shown in Fig. 2, in the plurality of sensors of the present invention, specific eigenvalues are assigned to the corresponding sensors.

2 shows an example in which a unique value of a binary number is assigned to the unique value of each sensor, but other unique values of other base systems may be assigned.

으로 1의 고유값이 할당 되어 있다.As shown in Figure 2, the intrinsic value of the thimble-shaped sensor 101 that is fitted to the thumb is

The eigenvalue of 1 is assigned.

으로 2의 고유값이 할당 되어 있다.The intrinsic value of the thimble-shaped sensor 102 that is inserted into the index finger is

The eigenvalue of 2 is assigned.

으로 4의 고유값이 할당 되어 있다.The intrinsic value of the thimble-shaped sensor 103 fitted to the middle finger is

The eigenvalue of 4 is assigned.

으로 8의 고유값이 할당 되어 있다.The intrinsic value of the thimble-shaped sensor 104 inserted into the ring finger is

The eigenvalue of 8 is assigned.

으로 8의 고유값이 할당 되어 있다.The intrinsic value of the thimble-shaped sensor 101 inserted into the little finger is

The eigenvalue of 8 is assigned.

In addition, a sensor fitted to each finger is connected to the wearable body 100 by an electric wire 106 for transmitting an electrical signal.

Here, in the wearable sensors 101, 102, 103, 104, and 105 of the present invention, almost no electricity is generated in a non-conductor such as a fiber, and when it comes into contact with the skin of a human body, a current is generated as described in FIG.

Therefore, when the thimble-type sensor (101, 102, 103, 104, 105) inserted into the finger contacts the skin, an electrical signal is generated, and when the generated electrical signal is greater than or equal to a preset threshold value, the sensor is recognized as a motion sensor and a unique value assigned to the motion sensor To identify.

3 is a diagram showing stored values corresponding to the summation of eigen values of sensors according to an embodiment of the present invention.

Fig. 3(a) is a diagram showing that the stored values corresponding to the summation of sensor eigenvalues are alphabets, and Fig. 3(b) is a diagram showing that the stored values corresponding to the summation of sensor eigenvalues are scales.

As described above, the storage unit 140 of the present invention stores a storage value corresponding to the summation of the sensor eigenvalues.

The wearable input/output device using the charging and static induction phenomenon of the present invention may be used as an input device or as an output device.

When used as an input device, it can be used as a keyboard for inputting characters.

When the wearable input/output device using charging and static electricity induction of the present invention is used as an input device, the stored value is stored as a value corresponding to the character information.

Fig. 3(a) shows that the stored value is an alphabet.

A description will be given of the use of the wearable input/output device using the charging and static induction of the present invention as an input device for inputting characters.

For example, when entering the character'DREAM', the sum of the eigenvalues corresponding to the stored value'D' is 4, the sum of the eigenvalues corresponding to the stored value'R' is 18, and corresponds to the stored value'E'. The sum of the eigenvalues is 5, the sum of the eigenvalues corresponding to the stored value'A' is 1, and the sum of the eigenvalues corresponding to the stored value'M' is 13.

Therefore, in order to input the character'DREAM', the user touches the skin with a thimble-shaped sensor 103 that is inserted into the middle finger within a certain period of time and converts it to a motion sensor, and the intrinsic value assigned to the sensor 103 By outputting 4,'D', which is the corresponding stored value, is generated as input information. Thereafter, within a certain period of time, the thimble-type sensor 102 fitted to the index finger and the thimble-type sensor 104 fitted to the ring finger contact the skin to be converted into a motion sensor and assigned to the corresponding sensors 102, 104. 18, which is the sum of the eigenvalues, is output, and the corresponding stored value,'R', is generated as input information. Thereafter, within a certain period of time, the thimble-type sensor 101 that is fitted to the thumb and the thimble-type sensor 103 that is fitted to the middle finger are in contact with the skin and are converted into motion sensors, and assigned to the corresponding sensors 101 and 103. By outputting 5, which is the sum of the eigenvalues, the corresponding stored value,'E', is generated as input information. Thereafter, within a certain period of time, the thimble-shaped sensor 101 that is fitted to the thumb is in contact with the skin and is converted into a motion sensor, and outputs 1, which is the sum of the unique values assigned to the sensor 101, and a stored value corresponding thereto. 'A' is created as input information. Thereafter, within a certain period of time, the thimble-type sensor 101 that is fitted to the thumb finger, the thimble-type sensor 103 that is fitted to the middle finger, and the thimble-type sensor 104 that is fitted to the ring finger are brought into contact with the skin. And outputs 13, which is the sum of the unique values allocated to the sensors 101, 103, and 104, and generates'M', which is a storage value, as input information.

Here, the input information corresponding to the generated'DREAM' may be transmitted to another input device through the communication unit 170 and the corresponding input information may be input. If the wearable body 100 additionally includes a display unit, the corresponding display unit It can also be displayed as text through.

As another embodiment, the wearable input/output device using the charging and static induction phenomenon of the present invention will be described as being used as an output device for sound output.

Fig. 3(b) shows that the stored value is a scale.

For example, in the case of outputting the sound of a scale called'Domisol', the sum of the eigenvalues corresponding to the stored value'Do' is 1, the sum of the eigenvalues corresponding to the stored value'Le' is 3, and the stored value ' The sum of the eigenvalues corresponding to'Sol' is 5.

Therefore, in order to output the sound of the scale, the user is assigned to the sensor 101 by contacting the skin with the sensor 101 in the form of a thimble inserted into the thumb within a certain period of time and converting it into a motion sensor. By outputting the eigenvalue 1, the corresponding stored value,'degree', is generated as sound output information. Thereafter, within a certain period of time, the thimble-type sensor 101 that is fitted to the thumb and the thimble-type sensor 102 that is fitted to the index finger are in contact with the skin and are converted into motion sensors and assigned to the corresponding sensors 101 and 102. 3, which is the sum of the eigenvalues, is output, and the corresponding stored value,'mi', is generated as sound output information. Thereafter, within a certain period of time, the thimble-type sensor 101 that is fitted to the thumb and the thimble-type sensor 103 that is fitted to the middle finger are in contact with the skin and are converted into motion sensors, and assigned to the corresponding sensors 101 and 103. By outputting 5, which is the sum of the eigenvalues, the corresponding stored value,'Sol', is generated as sound output information.

Through the above-described methods, the wearable input/output device using the charging and static induction phenomenon of the present invention may be used as a keyboard for inputting characters or as an acoustic information output device such as a piano for outputting sound.

4 is a diagram showing the configuration of a wearable body of a wearable input/output device using charging and static electricity induction according to an embodiment of the present invention.

Sensor signal input unit 110, threshold value comparison unit 120, eigenvalue summing unit 130, storage unit 140, sensitivity control unit 150, control unit 160, communication unit 170, input/output unit 180 ) Can be included.

The input unit 110 measures the sensor signal detected from the sensors 101, 102, 103, 104, and 105.

The threshold value comparison unit 120 has previously set a threshold value set by the user and compares the sensor signal measured through the input unit 110 with the set threshold value.

Here, in the wearable sensors 101, 102, 103, 104, and 105 of the present invention, almost no electricity is generated in a non-conductor such as a fiber, and when it comes into contact with the skin of a human body, a current is generated as described in FIG.

However, even when in contact with a non-conductor such as a fiber, electricity may be generated to some extent. Therefore, in order to generate meaningful information through an operation intended by the user, an electrical signal generated when the sensors 101, 102, 103, 104, and 105 unintentionally contact clothes such as fabric should not be determined as a meaningful signal.

Accordingly, the threshold value comparison unit 120 sets a threshold value, which is a reference value, in order to determine only an electrical signal generated by a user's intention by touching the sensor as a meaningful signal.

The eigenvalue summing unit 130 performs a function of summing eigenvalues allocated to all motion sensors in which a sensor signal equal to or greater than a threshold value is generated within a predetermined time.

A specific storage value corresponding to the summed eigenvalue is stored in the storage unit 140.

To this end, the storage unit 140 includes a memory.

The sensitivity control unit 150 controls the size of the threshold value to control the sensitivity of a sensor signal determined as a motion sensor.

When the threshold value is largely adjusted by the sensitivity adjusting unit 150, the sensitivity of the sensor decreases, and when the threshold value is decreased, the sensitivity of the sensor becomes sensitive.

The controller 160 adds up the intrinsic values of all motion sensors within a certain period of time, selects a stored value corresponding to the summed intrinsic value by referring to the storage unit 140, and receives the selected stored value through the communication unit 170. Control to transmit to an input device or other output device.

Also, the controller 160 may set a time interval at which the stored value is generated.

That is, in order to use the stored value corresponding to the sum of the eigenvalues as specific meaningful text information or sound output information by using a sensor, the generation time of the stored value must be made within a certain time.

The user can set such a predetermined time in advance through the control unit 160 so that the user can set a convenient time for generating text information or sound output information.

The communication unit 170 is configured to include a communication device and performs a function of transmitting a stored value to another device including the communication device. To this end, the communication device of the communication unit 170 may be configured as a low-power wireless communication device such as Wi-Fi or Bluetooth.

The input/output unit 180 performs a function of inputting a character using the corresponding character information when the stored value is character information, or outputting a sound by using the sound information when the stored value is sound information.

To this end, the input/output unit 180 may be configured to include a keyboard input circuit for inputting characters, or may include a speaker to output sound.

5 is a diagram illustrating an operation of a wearable input/output device using charging and static electricity induction according to an embodiment of the present invention.

Step S100 is a step of measuring a sensor signal, which is an electrical signal generated from the sensors 101, 102, 103, 104, and 105.

This is the step of determining whether the S200 sensor signal is greater than or equal to a set threshold value.

In step S300, when the sensor signal is greater than or equal to the threshold value, the sensor is determined as a motion sensor and a unique value assigned to the motion sensor is checked.

Step S400 is a step of determining whether the process of checking the eigenvalue exceeds a preset predetermined time.

As described above, in order to use the stored value corresponding to the sum of the eigenvalues using the sensor as specific meaningful text information or sound output information, the generation time of the stored value must be made within a certain time.

Therefore, it is necessary to determine whether the steps S100 to S300 are performed within a predetermined time in order to distinguish the stored values.

This predetermined time can be set in advance by the user, and thus can be set to be a convenient time for the user to generate text information or sound output information.

Step S500 is a step of summing the intrinsic values of all motion sensors determined within the predetermined time when a predetermined time is exceeded.

Step S600 is a step of outputting a stored value stored in the storage unit 140 corresponding to the summed eigenvalue.

Here, the stored value is transmitted to an input device using the stored value as input information or an output device using the stored value as output information.

Step S700 is a step of storing a unique value of a corresponding motion sensor when a predetermined time has not been exceeded as a result of determination in step S400. After that, all sensors are reset and the above-described steps are repeated from S100.

Until now, the present invention has been described in detail with reference to preferred embodiments, but those skilled in the art to which the present invention pertains can practice the present invention in other specific forms without changing the technical spirit or essential features thereof, The embodiments are illustrative in all respects and should be understood as non-limiting.
