Referring to FIGS. 1, 3 and 4 at the same time, the following exemplarily describes how the wearable posture monitoring device 1 of this embodiment implements a posture sensing method when the wearable posture monitoring device 1 is worn on the human body 9.

First, in step S1, the first sensing unit 13, the second sensing unit 14, and the third sensing unit 15 respectively output a first sensing data, a second sensing data, and a third sensing data. The measurement data is sent to the processing unit 18, and the first sensing data to the third sensing data indicate the acceleration changes sensed by the first sensing unit 13 to the third sensing unit 15 respectively.

More specifically, taking the first sensing data of this embodiment as an example, the first sensing data indicates, for example, that the first sensing unit 13 itself is in the X, Y, and Z axis directions in a three-dimensional space. The magnitude of the generated acceleration, in other words, the first sensing data indicates the displacement activity state of the first sensing unit 13 in the three-dimensional space through the acceleration change in the three-axis direction. It is supplemented that in the embodiment where the first sensing unit 13 is implemented as a six-axis acceleration sensor (that is, including both an accelerometer and a gyroscope), the first sensing data indicates the first The displacement and rotation activity state of a sensing unit 13 in a three-dimensional space, that is, the activity state of the first sensing unit 13 in six degrees of freedom (Six degrees of freedom). In addition, the implementable aspects, properties, and physical meanings of the second sensing data and the third sensing data are similar to those of the first sensing data, so they will not be described one by one here.

Moreover, since the first sensing unit 13 is located on the back side of the neck of the human body 9 in this embodiment, the first sensing data can indicate the cervical spine of the human body 9 (that is, the cervical vertebra C7) Or the activity state of the first thoracic spine (that is, thoracic spine T1). On the other hand, since the second sensing unit 14 is located in one of the ears of the human body 9 in this embodiment, the second sensing data can indicate the cervical atlas (that is, the cervical vertebrae) of the human body 9 C1) Activity status. On the other hand, since the third sensing unit 15 is located on the chest of the human body 9 in this embodiment, the third sensing data indicates the active state of the chest position of the human body 9.

Then, in step S2, after receiving the first sensing data to the third sensing data, the processing unit 18 generates an indication of the human body 9 based on the first sensing data and the second sensing data. According to the cervical spine posture data of the cervical spine angle, a thoracic spine posture data indicating the thoracic spine angle of the human body 9 is generated based on the first sensing data and the third sensing data. Moreover, in this embodiment, the angle of the cervical spine of the human body 9 is, for example, the angle difference between the cervical spine of the human body 9 and the direction of gravity (that is, the Z axis in the three-dimensional rectangular coordinate system), and the thoracic spine of the human body 9 The angle, for example, represents the angle difference between the thoracic spine of the human body 9 and the direction of gravity, but is not limited to this.

More specifically, the processing unit 18 may, for example, first calculate the first sensing unit 13, the second sensing data according to the first sensing data, the second sensing data, and the third sensing data. The direction in which the unit 14 and the third sensing unit 15 each face in the three-dimensional space. Then, the processing unit 18 calculates the cervical spine angle of the human body 9 according to the angle difference between the directions to which the first sensing unit 13 and the second sensing unit 14 face, thereby generating the cervical spine posture data. Moreover, the processing unit 18 also calculates the thoracic spine angle of the human body 9 according to the angle difference between the directions to which the first sensing unit 13 and the third sensing unit 15 face, thereby generating the thoracic spine posture data.

It is added that in other embodiments, the processing unit 18 can also be based on the first sensing unit 13 and the second sensing unit 14 by using the first sensing data to the third sensing data. The relative positional relationship between the three-dimensional space generates the cervical spine posture data, and the thoracic spine posture data is generated according to the relative positional relationship between the first sensing unit 13 and the third sensing unit 15 in the three-dimensional space, so The manner in which the processing unit 18 generates the cervical spine posture data and the thoracic spine posture data is not limited to this embodiment.

Next, in step S3, the processing unit 18 determines whether to control the prompt unit 16 to output a warning notice according to the cervical spine posture data and the thoracic spine posture data, and according to the actual implementation of the prompt unit 16, the warning notice can be For example, it is one or more of light, sound, and vibration. In this embodiment, the processing unit 18 judges whether a first warning condition is met according to the cervical spine posture data, and judges whether a second warning condition is met according to the thoracic spine posture data, for example. Moreover, if the processing unit 18 determines that one of the first warning condition and the second warning condition is met, the processing unit 18 controls the prompt unit 16 to output the warning notification. On the other hand, if the processing unit 18 determines that both the first warning condition and the second warning condition are not met, the processing unit 18 does not control the prompt unit 16 to output the warning notice, and, in this case , The process restarts from step S1.

In more detail, in this embodiment, the first warning condition means, for example, that the cumulative time period during which the angle of the cervical spine of the human body 9 is outside a first angle range reaches a first threshold. For example, the first angle range may be implemented as 0 to 20 degrees, and the first threshold value may be implemented as 15 minutes, for example. That is to say, if the processing unit 18 determines that the first warning condition is met, it means that the cumulative length of time that the human body 9 maintains the head down or tilted head posture has reached 15 minutes.

On the other hand, the processing unit 18 judges whether the second warning condition is met according to the thoracic spine posture data, and the second warning condition is, for example, the cumulative length of time that the thoracic spine angle of the human body 9 is outside a second angle range. A second threshold is reached. For example, the first angle range may be implemented as 0 to 15 degrees, and the second threshold value may also be implemented as 30 minutes, for example. That is to say, if the processing unit 18 determines that the second warning condition is met, it means that the cumulative length of time that the human body 9 maintains the kyphotic or scoliosis posture has reached 30 minutes.

It should be understood that because different human bodies may have inherent differences in structure, for different human bodies, the angles of the thoracic and cervical vertebrae used to assess whether their postures are correct may also be different from each other. Therefore, the first angle range The second angle range can be freely adjusted according to the actual conditions of different human bodies, and is not limited to this embodiment.

On the other hand, according to the application mode of the wearable posture monitoring device 1, the specific values of the first threshold value and the second threshold value can also be freely adjusted according to the requirements of different applications. For example, in a further implementation aspect, the wearable posture monitoring device 1 can switch between a head-up chest training mode, a daily posture monitoring mode, and a bicycle posture monitoring mode, and the first threshold value The specific values of the second threshold value and the second threshold value are, for example, different according to the current mode of the wearable posture monitoring device 1.

Specifically, in the head-up chest training mode, the first threshold value and the second threshold value can be implemented as a relatively short 5 seconds, for example, that is, the human body 9 only needs to lower its head or hunch back for 5 seconds. , The processing unit 18 will control the prompt unit 16 to output the warning notice, thereby, the wearable posture monitoring device 1 can remind the user to continuously maintain a posture with the head up and chest up. In addition, in the head-up and chest-up training mode, the processing unit 18 also generates and transmits a posture training history record containing the cervical spine posture data and the thoracic spine posture data to a mobile device for storage, so that the user can view it for head-up. The record of chest training.

On the other hand, in the daily posture monitoring mode, the first threshold value and the second threshold value can be implemented as a relatively long 30 minutes, for example, so that the wearable posture monitoring device 1 can remind the user to avoid Maintain a bowed or hunched posture for too long while reading, working or handling paperwork.

On the other hand, in the driving posture monitoring mode, the processing unit 18 will not only control the prompt unit 16 to output a warning notice when the first or second warning condition is met, but also calculate the human body 9 based on the cervical spine posture data. The number and frequency of nodding, and the processing unit 18 calculates a doze risk index based on the number and frequency of nodding of the human body 9 and the cumulative length of driving time, and when the doze risk index reaches a preset threshold The notification unit 16 is controlled to output a warning notification as a doze reminder, so that the wearable posture monitoring device 1 can not only remind the user of the bad posture when driving, but also further target the user who may be dozing off. The posture sends out a warning, and helps to improve driving safety.

In addition, in this embodiment, the alert notification output by the wearable posture monitoring device 1 will change its state over time, for example, so as to achieve the effect of staged prompting. More specifically, the processing unit 18 controls the prompt unit 16 to output different alarm notifications according to the accumulated time length (here, as a length of poor posture) when the first or second warning condition is met. For example, in the daily posture monitoring mode, if the bad posture time is between 0 and 30 minutes, the processing unit 18 controls the way in which the prompt unit 16 outputs a warning notification, such as controlling the light emitting element Glowing orange. Further, if the length of the bad posture time is greater than 30 minutes, the processing unit controls the prompt unit 16 to output a warning notification, for example, by controlling the light emitting element to emit red light and also controlling the buzzer to emit a warning sound. , But not limited to this.

Referring to FIG. 5, FIG. 5 shows a second embodiment of the wearable posture monitoring device 1 of the present invention. The difference from the first embodiment is that the wearable posture monitoring device 1 in the second embodiment only includes a single accessory 12, and in the second embodiment, the accessory 12 is implemented as one and the processing unit 18, for example. A wirelessly connected Bluetooth headset, and, in the second embodiment, when the main body 11 is worn on the human body 9, the first end 111 and the second end 112 of the main body 11 are located on the human body 9 (shown in Figure 3) The front side of the neck. Except for the above differences, the positional correspondence between the first sensing unit 13 to the third sensing unit 15 and the parts of the human body 9 in the second embodiment is the same as that of the first embodiment, and the wearable posture The posture sensing method implemented by the monitoring device 1 is also the same as the first embodiment, so it will not be repeated.

In summary, by implementing the posture sensing method, the wearable posture monitoring device 1 can determine whether the first warning condition is met based on the cervical spine posture data, or determine the second warning based on the thoracic spine posture data. A warning notification is output when the conditions are met, so that in the application of head-up and chest-up exercises, the wearable posture monitoring device 1 can assist the user in learning the correct posture of head-up and chest-up. On the other hand, in daily life posture monitoring applications The wearable posture monitoring device 1 can output a warning notification when it detects that the user has bowed his head or hunched for too long, thereby achieving the effect of reminding the user to actively adjust the posture. On the other hand, in the driving posture monitoring application, The wearable posture monitoring device 1 can further output a warning notification when the sleepiness risk index reaches a preset threshold. In this way, the wearable posture monitoring device 1 can not only remind the user to adjust the posture, but also help improve Driving safety. Therefore, the wearable posture monitoring device 1 can actively remind the user to recover from a bad posture in various applications, so it can indeed achieve the purpose of the invention.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited by this, all simple equivalent changes and modifications made in accordance with the scope of the patent application of the present invention and the content of the patent specification still belong to This invention patent covers the scope.
