DETAILED DESCRIPTION

In order to make the objects, technical solutions and advantages of the present disclosure more apparent, embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and the features in the embodiments in the present disclosure can be arbitrarily combined with each other without conflict.

FIG. 1 is a schematic view showing the composition of a wristwatch in the related art. As shown in FIG. 1, two electrodes are provided on the back of the wristwatch, and one electrode is provided on the face of the wristwatch. When the two electrodes on the back of the wristwatch are in close contact with one hand of a detected user and the other hand is in close contact with the electrode on the face of the wristwatch, the blood pressure detection can be achieved.

In order to achieve accurate blood pressure detection by the wristwatch, the detected user needs to keep a fixed posture within a certain time period, otherwise, the blood pressure detection is easy to fail. In order to make the two electrodes on the back tightly contact with the hand on which the wristwatch is worn, the other hand of the user is required to apply pressure to the wristwatch, and the operation experience of the detected user is poor. Once the blood pressure detection fails, the detected user needs to perform detection operation again, the detection efficiency is low, the use experience of the user is reduced, and the stability of the blood pressure detection process is poor. In addition to the blood pressure detection, the wristwatch, in most of the time, is configured to display the customized information including time, weather or the like. In the related art, the mode switching between the blood pressure detection and the display of the customized information is mainly realized through preset physical keys, so that the problem of inconvenience in user operation exists.

step 301: determining whether the wearable apparatus has been switched to a preset operating mode;

step 302: adjusting the wearable apparatus to satisfy the operating requirement of the current operating mode when it is determined that the wearable apparatus has been switched to the preset operating mode.

According to the embodiments of the present disclosure, the preset operating mode in the embodiments of the present disclosure comprises a blood pressure detection mode. Here, the blood pressure detection mode refers to a mode in which the wearable apparatus is switched to a function of detecting a blood pressure.

adjusting the wearable apparatus through a preset adjusting device to satisfy the operating requirement of the current operating mode when it is determined that the wearable apparatus has been switched to the preset operating mode.

The following provides a clear and detailed description of the method of the embodiments of the present disclosure by way of application examples, which are only intended for the purpose of illustrating the present disclosure and are not intended to limit the scope of the present disclosure.

Application Examples

The application examples are described by taking a wearable apparatus as a wristwatch and a preset operating mode as a blood pressure detection mode as an example. The wristwatch related to the application examples may be configured to display time, weather and other customized information in addition to the blood pressure detection. The application examples do not make any adjustments with respect to the display of information except the blood pressure detection with reference to the related art. FIG. 4 is a schematic view of a display of conventional information for an exemplary wristwatch according to the application examples of the present disclosure. As shown in FIG. 4, the customized information such as time, temperature, weather or the like is displayed on the display interface of the wristwatch. FIG. 5 is a schematic view of information displayed during a blood pressure detection by an exemplary wristwatch according to the application examples of the present disclosure. As shown in FIG. 5, data related to the blood pressure detection is displayed on the display interface of the wristwatch during the blood pressure detection. FIG. 6 is a schematic view of the distribution of various electrodes for blood pressure detection according to the application examples of the present disclosure. As shown in FIG. 6, the wristwatch comprises a display interface 601, a dial 602, a back 603 (the back case of the wristwatch) and a watchband 604. Based on the above structure, a first electrode is provided on the back 603 of the wristwatch; the second electrode is connected to the watchband 604, the end 604-1 of which is adapted to contact the skin of the detected user during the blood pressure detection; the dial 602 is a third electrode for detecting the blood pressure; the three electrodes are connected to a circuit board in the wristwatch in different ways to realize the detection of the electro cardio potential difference; a photoelectric tube 605 is provided in the back 603 of the wristwatch and is configured to detect the pulse information, and the blood pressure information may be obtained by combining the electro cardio potential difference detected by the electrodes and the pulse information detected by the photoelectric tube; the result of the blood pressure detection is displayed on the display interface 601.

When the blood pressure detection is carried out, the two hands of the detected user are required to cooperate for a certain time period. For example, for the wristwatch as shown in FIG. 6, when the adjusting device is not provided, the user needs to apply pressure to the wristwatch when the user uses one hand to contact the third electrode, so that the first electrode and the second electrode are in contact with the skin of the hand on which the wristwatch is worn, which satisfies the requirements. Thereby, the continuous electro cardio potential difference detection is performed. When the time is long, the detected user is easy to fatigue, and the detection process is easy to fail. According to the application examples, when it is determined that the trigger signal of switching to the blood pressure detection mode is detected, the preset adjusting device is configured to adjust the tightness of the watchband 604 of the wristwatch. Thus, without the pressing operation, the first electrode and the second electrode can be in contact with the skin of the hand on which the wristwatch is worn, which satisfies the detection requirement. Therefore, the blood pressure detection process is more convenient. After obtaining the information of the blood pressure detection, the application examples can automatically adjust the watchband 604 to the previous state and control the wristwatch to display the customized information.

The process of switching to the blood pressure detection mode and the process of adjusting the tightness of the watchband are respectively illustrated as follows.

The application examples detect and determine whether the wristwatch is switched to the blood pressure detection mode by a preset sensor. For example, a trigger operation satisfying a preset condition may be set with reference to an operation habit of the detected user. When the preset sensor detects the triggering operation, the triggering information is generated, and the wristwatch is switched to the blood pressure detection mode according to the generated trigger information.

FIG. 7 is a schematic view of the position of the wristwatch during daily wearing. As shown in FIG. 7, the wristwatch is generally at the lower end of the wrist due to the weight of the wristwatch itself, which is the loosest state of the watchband. When the user lifts a hand and needs to view the wristwatch, the user can sometimes support the wristwatch by the other hand to be convenient to view. Alternatively, the user can rotate the wrist with one hand, and when the arm is lifted, the wristwatch is also moved upwards, so that the watchband is clamped, and the wristwatch is fixed at a better position to be viewed. Based on the above habit, the embodiments of the disclosure set the following triggering operation with the following preset movement pattern to switch the wristwatch to the blood pressure detection mode. The triggering operation satisfying the preset condition according to the application examples comprises:

the wristwatch is in a preset angle range of movement during a preset time period with reference to a preset horizontal plane; and/or

a motion with a preset movement pattern occurs during a second preset time period.

The wearable apparatus being in the preset angle range of movement during the preset time period comprises: setting a horizontal plane according to the wearing angle of the wristwatch when the detected user views the wristwatch; and the angle at which the wristwatch performs a rotation movement during a certain time period is +/−30 degrees based on the set horizontal plane. FIG. 8 is a schematic view of the angle range of movement according to embodiments of the present disclosure. As shown in FIG. 8, all the range of 60 degrees as shown in the figure is the exemplary angle range of movement according to the application examples. The above angle set by the application examples can facilitate the user to view the result of the blood pressure detection on the wristwatch. The application examples can carry out the monitoring of the angle of movement of the wristwatch through a gyroscope sensor. According to the application examples, the motion with the preset movement pattern occurring during the second preset time period may comprise a simple touch operation, a click operation or the like. For example, the setting of the motion with the preset movement pattern based on the operation habit of the detected user may comprise:

the wrist of the detected user is rotated for more than the preset number of times during the second preset time period; the preset number of times may be 3. FIG. 9 is a schematic view of the motion of rotating a wrist according to the application examples of the present disclosure. As shown in FIG. 9, when the detected user rotates the wrist, the wristwatch will repeatedly move in the directions 1 and 2 as shown in the figure. According to the application examples, the damping vibration curve can be detected by the photoelectric tube. When the wrist of the detected user is rotated, the waveform as shown in FIG. 10 can be monitored by the infrared light emitted by the photoelectric tube, and the number of wave peaks is equivalent to the number of times of rotating the wrist.

According to the application examples, after the trigger signal is generated, the photoelectric tube emits green light to perform the blood pressure detection.

It should be noted that the above-mentioned exemplary operations may not be performed simultaneously, and allow a certain time difference. For example, two conditions may occur one after another within 3 seconds.

FIG. 11 is a schematic view of adjusting a tightness of a watchband according to the application examples of the present disclosure. As shown in FIG. 11, in order to make the first electrode and the second electrode have good contact with the skin, an adjusting device 11 may be provided at the end of the watchband according to the application examples. The adjusting device 11 may comprise: means configured to adjust the tightness of the watchband by taking a micro-motor as power. The realization principle thereof can be designed and realized by referring to the principle of the shrinkage of the mechanical arm of the micro robot. Namely, when it is switched to the blood pressure detection mode, the micro motor is enabled to control the tightness of the watchband, so that the first electrode and the second electrode can fit the skin better. When the blood pressure detection is completed, according to the application examples, the micro motor is controlled to restore the watchband to the state before the blood pressure detection, so that the tightness of the wristwatch worn by the detected user satisfies the requirement of comfort level. FIG. 12 is a schematic view showing a composition structure of a wristwatch according to the application examples of the present disclosure. As shown in FIG. 12, the wristwatch comprises a sensor 12-1, a micro motor 12-2, a photoelectric tube 12-3, a detection electrode 12-4 for detecting the electro cardio potential difference, a controller 12-5 and a display interface 12-6. The controller is configured to process the data collected by the sensor, control the operations of the micro motor and the photoelectric tube, and process the collected blood pressure detection data.
