DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The present invention provides a prompting method for measuring biological information, as shown in FIG1 , which provides a flow chart of the prompting method for measuring biological information.

It should be noted that, in this embodiment, the prompt method for biometric information measurement is implemented based on when the user contacts a biometric information measurement device, such as a wearable device such as a smart watch, or other terminal devices for biometric information measurement.

Specifically, referring to FIG. 1 , the above-mentioned bio-information measurement prompting method includes steps S102 to S108 as shown in FIG. 1 :

Step S102: identifying the touch pressure generated when the user touches the bio-information measuring device; Step S102 may be implemented by a detection component, such as a tactile sensor. Specifically, the tactile sensor may be configured on the bio-information measuring device.

Step S104: determining whether the touch pressure is within a preset pressure range; In step S104, the tactile sensor may be used to determine whether the touch pressure is within a preset pressure range. Specifically, the tactile sensor may be configured on the bio-information measuring device.

Step S106: determining the distribution of the touch pressure in the preset pressure range; In step S106, the distribution of the touch pressure in the preset pressure range may be determined by the tactile sensor. Specifically, the tactile sensor may be configured on the bio-information measuring device.

Step S108: Generate and output at least one of a tactile feedback signal and an optical feedback signal as prompt information based on the distribution. Step S108 can be implemented by a detection component. The detection component itself can have light and can also include one or more indicator lights.

In one embodiment, the tactile sensor can be configured on the contact surface between the bio-information measuring device and the human body. For example, the tactile sensor is configured on the back of a smart watch. When a user wears a wearable device, the tactile sensor contacts the human body. In this case, the wearing pressure (the touch pressure of the tactile sensor relative to the skin on the outside of the human body) will affect the measurement of bio-information. In another embodiment, the tactile sensor can also be configured on the outside of the bio-information measuring device. For example, the tactile sensor is configured on the side or front of a smart watch. When a user wears a wearable device, the user can touch or press the tactile sensor with a finger. In this case, the touch pressure of the finger will affect the measurement of bio-information.

In this embodiment, the touch pressure generated when the user touches the bioinformation measuring device (including the touch pressure corresponding to the wearing pressure and the touch pressure of the finger) is explained using the finger as an example in the following description for the convenience of description, but the touch pressure corresponding to the wearing pressure of the user wearing the wearable device is also included.

In one embodiment, before the step of determining whether the touch pressure is within a preset pressure range, the prompt method further includes: testing the touch pressure generated when the user contacts the bio-information measuring device multiple times under different user skin thicknesses; and taking the maximum and minimum values of multiple touch pressure test data as the upper and lower limits of the preset pressure range.

In one embodiment, the touch pressure test data obtained by the tactile sensor is different in the case of different user skin thicknesses. For example, some people have thicker skin (for example, there are a few calluses on their fingers). Of course, the touch pressure test data obtained by the tactile sensor is also different in the case of different touch pressure sizes. It is necessary to test the touch pressure generated when the user contacts the bioinformation measurement device multiple times according to different touch pressure sizes under different user skin thicknesses, and take the maximum and minimum values of multiple touch pressure test data as the upper and lower limits of the preset pressure range to obtain the preset pressure range. For different users, the preset pressure range can also be personalized, and the preset pressure range is determined by obtaining personalized parameters. Among them, the user personalized parameters include one or more of age, gender, height, weight, physical examination data, and historical detection data.

By testing the touch pressure generated when the user contacts the bioinformation measuring device multiple times under different user skin thicknesses, and taking the maximum and minimum values of the multiple touch pressure test data as the upper and lower limits of the preset pressure range, touch pressure calibration is achieved under different skin thicknesses and different touch pressure sizes.

In one embodiment, when the touch pressure is within the preset pressure range, outputting the prompt information can be used to prompt that the touch pressure is within the preset pressure range; when the touch pressure is higher than the upper limit of the preset pressure range, outputting the prompt information can be used to prompt to reduce the touch force; when the touch pressure is lower than the lower limit of the preset pressure range, outputting the prompt information can be used to prompt to increase the touch force.

As an example only, the preset pressure range is set to a~b, where a represents the lower limit of the preset pressure range, b represents the upper limit of the preset pressure range, the touch pressure is set to x, and the tactile feedback signals "A", "B", "C", etc. are set. The tactile feedback signals "A", "B", "C", etc. are used to distinguish similar parts and do not have to be used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances so that the embodiments of the present application described herein can be implemented in an order other than that illustrated herein.

Specifically, when the touch pressure a≤x≤b, a tactile feedback signal A is generated to prompt that the touch pressure is within the preset pressure range; when the touch pressure x＞b, a tactile feedback signal B is generated to prompt that the touch pressure is higher than the upper limit of the preset pressure range and the touch force needs to be reduced; when the touch pressure x＜a, a tactile feedback signal C is generated to prompt that the touch pressure is lower than the lower limit of the preset pressure range and the touch force needs to be reduced; of course, when the touch pressure x＜a, no tactile feedback signal may be generated to prompt that the touch pressure is lower than the lower limit of the preset pressure range.

In one embodiment, the tactile sensor obtains biological information and extracts feature points in the biological information, and calculates the change ratio of the number of feature points in a set number. When the change ratio reaches a preset ratio, the prompt information is output to prompt the progress of the biological information measurement.

In one embodiment, when the change ratio reaches the preset ratio, the prompt information is output at least once to prompt the progress of the biological information measurement, and the preset ratio has one or more increasing percentages.

In one embodiment, when the preset ratios are set to 20%, 40%, 60%, 80% and 100% respectively, the prompt information is outputted to prompt that the progress of the bio-information measurement is 20%, 40%, 60%, 80% and 100% respectively.

Specifically, the tactile sensor can be configured on the bio-information measurement device, and the tactile feedback signal is set to be the same. When the calculated change ratio of the number of feature points in the set number is 20%, 40%, 60%, 80% and 100%, a tactile feedback signal D is generated to prompt that the progress of the bio-information measurement is 20%, 40%, 60%, 80% and 100%. The tactile feedback signal can also be set to be different. For example, the tactile feedback signal can be set to increase or decrease according to the gradient. When the calculated change ratio of the number of feature points in the set number is 20%, 40%, 60%, 80% and 100%, tactile feedback signals D, E, F, G, and H are generated respectively to prompt that the progress of the bio-information measurement is 20%, 40%, 60%, 80% and 100%. It is also possible to set the first four tactile feedback signals to be the same, and the tactile feedback signals at the time of completion to be different. When the change ratio of the number of feature points in the set number is calculated to be 20%, 40%, 60%, 80% and 100%, tactile feedback signals D, D, D, D, H are generated respectively to indicate that the progress of the bio-information measurement is 20%, 40%, 60%, 80% and 100%. In this embodiment, according to the change ratio of the number of feature points in the set number, the tactile feedback signal is generated by the tactile sensor as prompt information and output to indicate the progress of the bio-information measurement, so that the user can always perceive the progress of the bio-information measurement. The preset ratio can also be set to 10%, 30%, 50%, 70%, 90% and other all percentages. The preset ratio can also be set to at least one increasing percentage. For example, the preset ratio can be set to 50%, and can also be set to 30%, 70% and other all percentages to indicate the progress of the bio-information measurement.

In one embodiment, the prompt information is output when the biological information measurement is started, stopped, an exception occurs, or ends.

Specifically, the tactile sensor can be configured on the bio-information measurement device. When the bio-information measurement is started, the tactile sensor generates a tactile feedback signal D. Of course, the tactile sensor can also generate a tactile feedback signal I to prompt the start of the bio-information measurement; when the bio-information measurement is terminated, the tactile sensor generates a tactile feedback signal J to prompt the termination of the bio-information measurement; when an abnormality occurs in the bio-information measurement, the tactile sensor generates a tactile feedback signal K to prompt that the bio-information measurement needs to be restarted; when the bio-information measurement ends, the tactile sensor generates a tactile feedback signal L to prompt the end of the bio-information measurement. Of course, the tactile sensor can also generate a tactile feedback signal H, which is the same as the tactile feedback signal generated by the tactile sensor when the bio-information measurement progress is 100%. This embodiment allows the user to perceive the measurement status of the bio-information through the tactile feedback signal, including one or more of the measurement start, measurement termination, measurement abnormality and measurement end states, and can also be other bio-information measurement states.

In one embodiment, the tactile sensor can be configured on the contact surface between the bio-information measuring device and the human body. For example, the tactile sensor can be configured on the back of a smart watch. When the user wears the wearable device, the tactile sensor contacts the human body, and a tactile feedback signal is generated by the tactile sensor as prompt information and output. In another embodiment, the tactile sensor can also be configured on the outside of the bio-information measuring device. For example, the tactile sensor can be configured on the side or front of the smart watch. The user can touch or press the tactile sensor with a finger, and a tactile feedback signal is generated by the tactile sensor as prompt information and output, so that the user can perceive the measurement situation without viewing the display device.

In one embodiment, the indicator light can also be configured on the bioinformation measuring device. The indicator light can be configured at a position that is convenient for the user to see. For example, the indicator light can be configured on the side or front of a smart watch. When the user wears the wearable device, an optical feedback signal is generated by the indicator light and output as prompt information. For some users whose peripheral nerves are not sensitive, the optical feedback signal is used as prompt information and output, which is easier to distinguish.

In one embodiment, the tactile sensor and the indicator light can be configured on the bioinformation measuring device at the same time. For example, the tactile sensor is configured on the back of a smart watch, and the indicator light is configured on the side or front of the smart watch. When a user wears the wearable device, a tactile feedback signal is generated by the tactile sensor, and an optical feedback signal is generated by the indicator light. The tactile feedback signal and the optical feedback signal are output together as prompt information.

Furthermore, the tactile feedback signal may be a vibration signal. For example, the vibration signal may include the strength of the vibration amplitude, the vibration frequency, and the feeling of vibration intermittence, etc. The vibration signal may also include the feeling of friction. For example, the feeling of friction may be one or more of the feelings of bumpy, smooth, and rough.

The optical feedback signal may be one or more of a light color signal, a light brightness signal, and an intermittent light signal.

Furthermore, after the tactile feedback signal and/or the optical feedback signal is generated, the prompt method further includes: denoising the tactile feedback signal and/or the optical feedback signal to ensure that the output prompt information is free of noise interference so as to output accurate measurement results.

It should be noted that the bio-information measurement prompt method can be used for detecting pulse wave waveforms, and can also be used for detecting ECG (electrocardiogram) or other body signal detections. Of course, the bio-information measurement prompt method can be used for detecting body indicators such as blood pressure, heart rate, blood oxygen, and can also be used for detecting other body indicators.
