The wearable device 1 further comprises a CPU and a motion detection device, wherein the CPU is respectively in communication connection with the voltage detection device and the motion detection device;
when the skin of the user contacts the second body 21, the second body 21 is conducted with the internal circuit through the skin of the user and the conductive contact 13, the power supply voltage is input into the internal circuit, at the moment, the voltage detection device detects the internal voltage of the internal circuit, the CPU starts the motion detection device after acquiring that the internal voltage is in a preset threshold range, the motion detection device records the motion track of the wearable device 1 and uploads the motion track to the CPU, and the CPU converts the motion track into corresponding characters or pictures and displays the corresponding characters or pictures on the wearable device 1.

In some embodiments, the preset threshold range may be set appropriately according to actual requirements. For example, when the second body 21 of the peripheral voltage output device 2 is a mobile phone, the user holds the mobile phone with his left hand and wears the first body 11 with his right hand, then when the left hand and the right hand of the user are not in contact, i.e. the user is not in writing state, the power voltage output by the mobile phone reaches the voltage detection device on the body through the left hand, the chest and the right hand of the user, at this time, the power voltage is divided due to the resistance of the human body, and the internal voltage detected by the voltage detection device is V 1 The method comprises the steps of carrying out a first treatment on the surface of the When the right hand of the user contacts the mobile phone, namely, when the user is in a writing state, the voltage output by the mobile phone respectively passes through the right hand and the left hand of the user and reaches the voltage detection device on the body, at the moment, the resistance value of the human body resistor becomes smaller because of the parallel connection relationship generated inside the human body resistor, and at the moment, the internal voltage detected by the voltage detection device is V 2 From ohm's law, we know V 2 Greater than V 1 . Thus can be provided with V 1 Is not within the preset threshold range of the internal voltage, but V 2 Within a preset threshold range of the internal voltage, thus when the userWhen left-right hand contact of (a) is detected that the internal voltage is V 2 When the motion detection device detects the motion trail of the first body 11 (the wearable device 1), the purpose of accurately recording the motion trail is achieved. The motion detection device is used for recording a motion track of the first body 11, and because the first body 11 is worn on a hand or other body parts of a user, when the user writes with a pen by wearing the body parts of the first body 11, that is, recording the motion track of the hand or other body parts wearing the first body 11 of the user, that is, the track of writing characters or pictures in progress by the user, and uploading the motion track to the CPU; after the CPU accepts the recorded motion trajectories, the motion trajectories are converted into characters by the trajectory conversion recognition program and displayed on the wearable device 1, thereby completing the content input on the smart wearable device 1. In some embodiments, the first body 11 of the wearable device 1 may not have the screen 14, and the first body 11 may not directly display the input content, but directly send the input content to another intelligent terminal, so that the purpose that the wearable device 1 can send the message without the screen 14, such as a bracelet, is achieved. In some embodiments, two preset threshold ranges of the internal voltage are set, and accordingly, the power supply voltage output by the peripheral voltage output device 2 can also be adjusted, when the detected internal voltage is in the first preset threshold range, the content which the user wants to input currently is considered to be characters, namely, the recorded motion trail corresponds to strokes of the characters, and the content converted according to the motion trail is also characters; when the detected internal voltage is in the second preset threshold range, the content which the user wants to input currently is considered to be the picture, namely, the recorded motion trail corresponds to the line of the picture, the content converted according to the motion trail is also the picture, and the user can achieve the purpose of inputting the mixed content of the characters and the picture by switching the internal voltage in different preset threshold ranges, so that the input content is more abundant and various in form. With the above arrangement, in some embodiments, the user can write directly on the surface of the peripheral voltage output device 2, and when the user performs stroke writing, the user and the peripheral are powered onThe surface of the voltage output device 2 is contacted, at this moment, the external voltage output device 2 is conducted with the wearable equipment 1, the power supply voltage is input into the internal circuit, the voltage detection device detects that the internal voltage is within the preset threshold range, then the motion track of the first body 11 is detected through the motion detection device, namely, the writing track of the user is detected, when the user finishes writing strokes, the body part of the user writing leaves the surface of the external voltage output device 2 and is not contacted with the external voltage output device 2, the voltage detection device detects that the internal voltage is not within the preset threshold range, at this moment, the motion detection device does not record the motion track of the first body 11, finally, the motion track recorded by the motion detection device is converted into characters to be displayed in the screen 14 of the intelligent wearable equipment through the CPU, the purpose of inputting contents on the intelligent wearable equipment is achieved, the CPU can intelligently recognize characters corresponding to the motion track of the user, for example, continuous strokes and the surface of the external voltage output device 2 is equivalent to a handwriting keyboard to input characters. In other embodiments, the user may not write directly on the surface of the peripheral voltage output device 2, for example, by setting the device so that the user's right hand wears the smart watch, and when writing strokes, the user's left hand contacts with the peripheral voltage output device 2, the voltage detection device also detects that the internal voltage is within the preset threshold range, at this time, the motion detection device detects the motion track of the first body 11 in real time, the user's right hand can write the track of the strokes on the surface of the desktop or other objects even in the air, and when the user finishes writing, the user only needs to leave the peripheral voltage output device 2, and then the CPU converts the motion track recorded by the motion detection device into a text and displays the text on the screen 14 of the smart wearable device.
In some embodiments, the motion detection device includes a gyroscope 12 and an acceleration sensor, where the gyroscope 12 is used to detect the angular velocity of the body motion, the detection result is relatively accurate in a shorter time and there is an error due to motion drift for a longer time, and is relatively suitable for detecting the motion trail when the user writes at a slower writing speed and strokes by strokes, while the acceleration sensor is used to detect the linear acceleration of the first body 11, the measurement value of the acceleration sensor is correct in a longer time, and there is a small error due to the presence of signal noise in a shorter time, and is relatively suitable for detecting the motion trail when the user writes at a faster writing speed and writing with continuous strokes results in a single writing time being longer. The motion detection device adopts the combination of the gyroscope 12 and the acceleration sensor, can more accurately record the motion trail under various different writing conditions, and enables the CPU to more accurately convert corresponding characters according to the recorded motion trail.
In some embodiments, the first body 11 further includes a first switch, and the first switch is used to start or close the voltage detection device, and when the user needs to write, the first switch needs to be turned on first, and the voltage detection device is in an operating state and detects the internal voltage. The first switch is provided for the purpose of preventing erroneous operation of the voltage detecting device. In life, the surfaces of many objects are also provided with voltages with smaller values, such as various electric appliances, batteries and the like. If the voltage detection device is always in an on state, there are cases when the user touches some objects with output voltage, so that the internal voltage is just within a preset threshold range, and the user does not write input will and operation at this time, but the motion detection device still detects the motion trail according to the detection result of the voltage detection device, thus causing misoperation and bringing inconvenience to the user. The first switch is used for controlling the opening or closing of the voltage detection device, and when a user needs to write, the first switch is opened, namely the voltage detection device is opened, and at the moment, the voltage detection device detects the internal voltage of the internal circuit so that the motion detection device can detect the motion trail; when the user does not need to write, the first switch is turned off, namely the voltage detection device is turned off, and at the moment, the motion detection device cannot detect the motion trail of the first body 11, so that inconvenience brought to the user by misoperation is avoided.
In some embodiments, the peripheral voltage output device 2 includes a human body induction switch, for example, an infrared induction switch, and the human body induction switch is used for starting or closing the peripheral voltage output device 2, specifically, the power supply 22 of the peripheral voltage output device 2 applies a power supply voltage to the second body 21 through a circuit, when the human body induction switch senses that a human body approaches, the power supply is in an open state, and a connection circuit between the power supply 22 and the second body 21 is conducted, so that the power supply voltage can be applied to the second body 21, that is, the peripheral voltage output device 2 outputs the power supply voltage to detect the internal voltage by the power supply voltage detection device; when the human body induction switch does not sense that a human body approaches in the preset time, the human body induction switch is turned off, a connecting circuit between the power supply 22 and the second body 21 is disconnected, so that the power supply voltage cannot act on the second body 21, namely the peripheral voltage output device 2 stops outputting the power supply voltage, and when a user does not need to write, the energy can be better saved.
In some embodiments, the peripheral voltage output device 2 further includes a second switch for controlling the peripheral voltage output device 2 to be turned off or turned on, because the peripheral voltage output device 2 may output a power supply voltage when other animals are close even though the peripheral voltage output device 2 is provided with a human body sensing switch, thereby wasting energy. Therefore, when the user does not need to use the peripheral voltage output device 2 for a long time, the power supply 22 of the peripheral voltage output device 2 can be turned off through the second switch, so that the peripheral voltage output device 2 stops outputting the power supply voltage, and further energy is saved.

In some embodiments, the wearable device further includes a timer, the timer is in communication connection with the CPU, and when the internal voltage is monitored to be in the preset threshold range, the CPU obtains, in real time, a timing time of the timer to calculate a duration time of the internal voltage being in the preset threshold range; after step S1 of recording the motion trail when the internal voltage is detected to be within the preset threshold range, the method further includes:
s01: and if the duration time of the internal voltage in the preset threshold range exceeds the preset time threshold, stopping recording the motion trail.
In the step S01 of stopping recording the motion trail if the duration of the internal voltage within the preset threshold range exceeds the preset time threshold, the purpose of setting the preset time threshold for the duration of the internal voltage within the preset threshold range is mainly two, firstly, the user does not continuously attach the writing tool to the writing position all the time during normal writing, and there is a process of leaving the writing position between the words, that is, the internal voltage is not within the preset threshold range, and then returning to the writing position, that is, the internal voltage is within the preset threshold range again, even if there is a condition of writing with continuous strokes, the duration is not too long. Therefore, if the duration of the internal voltage within the preset threshold range exceeds the preset time threshold, the internal voltage may not be in a normal writing state at present, but may be in a misoperation or not operated by the user himself, so that the detection of the motion trail of the first body is stopped to prevent the trouble to the use of the user. Secondly, if long-time continuous writing is performed, the motion trail is too much, the recording accuracy of the motion trail is affected, the character conversion of the CPU is also affected, and the situation of inaccurate motion trail identification is easy to occur. And therefore, if the duration of the internal voltage in the preset threshold range exceeds the preset time threshold, stopping recording the motion trail.
In some embodiments, when the internal voltage is detected to be within the preset threshold range, step S1 of recording a motion track includes:
s11: when the internal voltage is monitored to be in a preset threshold range, acquiring real-time movement direction and distance data of the first body;
s12: and converting the real-time movement direction and distance data into movement tracks and recording.
In the step S11 of collecting the real-time motion direction and distance data of the first body when the internal voltage detected by the voltage detection device is within the preset threshold range, that is, when the internal voltage detected by the voltage detection device is in the preset threshold range, the human body of the user is considered to be in contact with the peripheral voltage output device, that is, the user is considered to be in a state of being ready to write to realize the content input of the intelligent wearable device, at this time, the CPU starts the motion detection device, and the motion detection device acquires the motion track of the user by detecting the motion data of the real-time motion direction, the distance and the like of the first body.
In the step S22 of converting the real-time motion direction and distance data into a motion track and recording, the motion detection device converts the real-time motion direction and distance data into a motion track corresponding to the written strokes after detecting the real-time motion direction and distance data of the first body. In some embodiments, the motion detection device includes a gyroscope and an acceleration sensor, where the gyroscope is used to detect the angular velocity of the motion of the body, the detection result is relatively accurate in a shorter time and there is an error due to motion drift for a longer time, and the motion detection device is relatively suitable for detecting the motion trail when the user writes at a slower writing speed and strokes by strokes, while the acceleration sensor is used to detect the linear acceleration of the body, and the measurement value of the acceleration sensor is correct for a longer time, and there is a small error due to the presence of signal noise in a shorter time, and the motion detection device is relatively suitable for detecting the motion trail when the user writes at a faster writing speed and the writing time of a single stroke is longer due to continuous writing.
The invention provides an input method of intelligent wearable equipment, which comprises the following steps: s1: when the internal voltage is monitored to be in a preset threshold range, recording a motion track; s2: converting the motion trail into characters or pictures. When the voltage detection device detects that the internal voltage is in the preset threshold range, the motion detection device records the motion trail written by the user operating the first body, then the motion trail is converted into corresponding characters or pictures through the CPU to be input on the wearable device, which is equivalent to externally connecting a virtual handwriting keyboard to the intelligent wearable device, and the writing trail of the user is displayed on a screen to finish the input, so that the aim of rapidly and accurately inputting the character information even the picture information on the intelligent wearable device is fulfilled.
