[0018] Various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms and should not be construed as being limited to any specific structure or function given throughout the present disclosure. On the contrary, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. It should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether it is realized independently of any other aspect of the present disclosure or realized in combination with any other aspect of the present disclosure. For example, any number of aspects disclosed can be used to realize a device or practice method. In addition, the scope of the present disclosure is intended to cover such a device or method that is practiced using other structures, functions, or structures and functions other than the various aspects of the present disclosure set forth herein or different from the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein can be embodied by one or more elements of the claims.

[0019] Wearable devices can be used to obtain biometrics associated with the wearer (e.g., user) of the wearable device. In one example, a smart watch can be used to obtain a blood pressure measurement of the wearer. Sometimes, the accuracy of the biometric measurement may be affected by the way the wearer wears the wearable device. For example, the smart watch can be worn at various locations along the wearer's arm and / or the band for the smart watch can be tightened to the wearer's arm with varying tightness. These variables affect the pressure between the smart watch and the wearer's arm, thereby affecting the accuracy of the biometrics (such as blood pressure measurements) taken by the smart watch. In particular, the smart watch can utilize photoacoustic signal generation to take blood pressure measurements or other biometrics, and changes in the applied pressure can change the photoacoustic signal received at the sensor of the smart watch. Therefore, the smart watch may not be able to consistently take accurate and reliable blood pressure measurements or other biometrics. In some cases, this lack of consistency may result in repeated measurements, thereby consuming excessive resources of the smart watch (e.g., processing resources, memory resources, and / or battery resources, as well as other examples).

[0020] In some techniques and devices described herein, a user device may monitor the pressure at the interface between the user device and the body (e.g., arm) of the user of the user device, and the user device may provide an indication to the user whether the pressure is to be adjusted to within the range for obtaining data for biometrics. For example, an indication may be provided in a user interface presented on a display of the user device. In response to the indication, the user may increase, decrease, or maintain the pressure (e.g., by applying pressure to the user device or reducing the pressure applied to the user device). In this way, the user device may obtain accurate biometrics. In addition, the user device may obtain accurate biometrics on the first try, thereby reducing the number of measurements performed and saving resources of the user device (e.g., processing resources, memory resources, and / or battery resources, as well as other examples). In addition, the user device may obtain accurate biometrics without using a pressure regulating airbag in the user device, thereby improving the form factor of the user device and promoting miniaturization.

[0032] Transmitter 245 includes a component configured to transmit a signal from device 200. For example, transmitter 245 may include an optical transmitter configured to transmit an optical signal.

[0037] Figure 2 The number and arrangement of components shown in the figure are provided as examples. In practice, the device 200 may include Figure 2 Additional components, fewer components, different components, or differently arranged components may be included in the components shown in FIG. Additionally or alternatively, one set of components (eg, one or more components) of device 200 may perform one or more functions described as being performed by another set of components of device 200.

[0038] Figure 3A-3B 3 and 4 are front and rear views, respectively, of an example user device 300 (eg, which may correspond to user device 110). As described herein, user device 300 may be a wearable device, such as a wearable device configured to be attached to a user's arm. For example, in Figure 3A-3B In the embodiment of the present invention, the user device 300 is shown as a smart watch. However, in some aspects, the user device 300 may be another type of wearable device (eg, a smart armband or a smart ring), or the user device 300 may be a device that is not configured for wear.

[0039] As shown, user device 300 may include device component 302 and at least one strap 304 (shown as two straps 304 that may be connected together by a buckle, clasp, etc.) connected to device component 302. Strap 304 (e.g., a wristband) may enable user device 300 to be attached to a user's arm (e.g., a wrist or finger). User device 300 (e.g., device component 302) may include a device configured to perform the operations described herein (such as in conjunction with Figure 4A-4C The operations described herein may be performed by one or more processors.

[0040] like Figure 3A As shown, a first side of user device 300 (e.g., a first side of device component 302) may include display 306 (e.g., corresponding to output component 230). Display 306 may be configured to present a user interface. For example, the user interface may include an input element that enables initiation of a biometric operation (e.g., a blood pressure measurement operation).

[0041] like Figure 3B As shown, the second side of the user device 300 opposite to the first side (e.g., the second side of the device component 302) may include a pressure sensor 308 (e.g., corresponding to the pressure sensor 240). The pressure sensor 308 may be configured to detect pressure at an interface between the body (e.g., wrist) of a user (e.g., wearer) of the user device 300 and the user device 300. The interface may be a contact point between the second side of the user device 300 and the user's body. For example, the pressure sensor 308 or a portion thereof may protrude from the surface of the device component 302, or the pressure sensor 308 may be flush with the surface of the device component 302. In this way, when the user wears the user device 300, the pressure sensor 308 contacts the user's body. In some aspects, the second side of the user device 300 may also include a transmitter 310 (e.g., corresponding to the transmitter 245) to transmit a signal at the user's body and / or a sensor 312 (e.g., corresponding to the sensor 250) to detect a reflection of the transmitted signal or a signal generated by the transmitted signal. For example, the transmitter 310 may be configured to transmit a light signal (e.g., a near infrared or infrared light signal) at the user's body, and the sensor 312 may be configured to detect sound waves (e.g., ultrasound waves) generated by the photoacoustic effect when the light signal interacts with the user's body. As another example, the transmitter 310 may be configured to transmit a light signal (e.g., a near infrared or infrared light signal) at the user's body, and the sensor 312 may be configured to detect light reflected back from the user's body (e.g., blood).

[0042] The user device 300 may include a rotatable element configured to cause actuation (e.g., protrusion or retraction) of the pressure sensor 308 (and the emitter 310 and / or the sensor 312) to adjust the pressure at the interface between the user's body and the user device 300 (e.g., by actuating the pressure sensor 308 toward or away from the user's body). The actuation of the pressure sensor 308 may include actuation of a surface (e.g., a plate or substrate) supporting the pressure sensor 308 (and the emitter 310 and / or the sensor 312). In some aspects, the rotatable element may be mechanically linked to the pressure sensor 308 or a surface including the pressure sensor 308 via one or more gears, one or more screws, etc., such that rotation of the rotatable element causes actuation of the pressure sensor 308 via the mechanical linkage. In some aspects, the rotatable element may be a control for actuating the pressure sensor 308, and the actuation of the pressure sensor 308 may be achieved via an actuation component (e.g., a linear actuator) of the device component 302. In some aspects, the rotatable element can be a knob 314 (also referred to as a “crown” in the case of a smartwatch) connected to device component 302 of user device 300. Additionally or alternatively, the rotatable element can be a bezel 316 surrounding display 306.

[0043] As mentioned above, Figure 3A-3B are provided as examples. Other examples can be found in the Figure 3A-3B The examples described are different.

[0044] Figure 4A-4C is a diagram of an example 400 associated with pressure regulation for biometry. Figure 4A-4C As shown, example 400 includes combining Figure 1-Figure 2 and Figure 3A-3B The user equipment described in more detail. For example, the user equipment may correspond to the user equipment 300.

[0045] like Figure 4A In the figure and shown by reference numeral 405, the user device can initiate a biometric operation associated with a user of the user device. The user of the user device can wear the user device (e.g., on the user's arm). The biometric operation can be a blood pressure measurement operation. Additionally or alternatively, the biometric operation can be a heart rate measurement operation, a heart rate variability measurement operation, and / or a pulse oximetry measurement operation, among other examples. The user device can periodically initiate the biometric operation in response to a request from the user (e.g., in response to an input to the user device indicating a request to initiate the biometric operation) or in response to a triggering event.

[0046] As shown in reference numeral 410, in conjunction with the biometric operation, the user device may monitor pressure at the interface between the user's body (e.g., arm) and the user device. For example, the user device may monitor whether the pressure at the interface between the user's body and the user device is within a range (e.g., about 30 millimeters of mercury (mmHg) to about 40 mmHg) used to obtain data for biometrics (e.g., blood pressure measurements, heart rate measurements, heart rate variability measurements, and / or pulse oximetry measurements, etc.). The user device may monitor pressure using a pressure sensor of the user device (e.g., pressure sensor 308).

[0047] like Figure 4B As shown, and by reference numeral 415, the user device can provide an indication of whether the user wants to adjust the pressure based on whether the pressure is within the range used to obtain the data. In particular, the user device can provide an indication of whether the user should increase the pressure to within the range, decrease the pressure to within the range, or maintain the pressure within the range based on whether the pressure is within the range. When the user device is monitoring the pressure, the user device can provide the indication in real time.

[0048] The user device may provide an indication via an output component of the user device. For example, the output component may be a display (e.g., display 306). Here, the indication may be provided by a user interface element of a user interface presented on the display. The user interface element may include a meter (e.g., to show the difference between the current pressure and the range) or a color indicator (e.g., a red indicator indicating that the current pressure is out of range or a green indicator indicating that the current pressure is within range). As another example, the output component may be a speaker. Here, the indication may be provided by one or more sounds (e.g., a first sound indicating that the current pressure will be increased, a second sound indicating that the current pressure will be reduced, or a third sound indicating that the current pressure will be maintained). As another example, the output component may be a vibration component. Here, the indication may be provided by one or more vibration modes (e.g., a first mode indicating that the current pressure is to be increased, a second mode indicating that the current pressure is to be reduced, or a third mode indicating that the current pressure is to be maintained).

[0049] Based on the indication, the user can use one or more techniques to adjust the pressure. In one technique, the user can use a hand or finger to apply pressure to the user device (e.g., to a display of the user device), or the user can reduce the pressure applied to the user device. In another technique, the user can adjust the tightness of the strip (e.g., strip 304) of the user device. In another technique, the user can pull the strip or insert a finger between the strip and the user's body (e.g., the user's arm). In another technique, the user can rotate a rotatable element (e.g., knob 314 and / or frame 316) of the user device, which actuates the pressure sensor toward or away from the user's body. In another technique, the user can adjust the longitudinal position of the user device on the user's arm (e.g., toward the user's hand to reduce pressure or toward the user's elbow to increase pressure), on the user's leg, etc. In some aspects, the indication can indicate the way the user wants to adjust the pressure (e.g., the indication can indicate that the user wants to use one or more of the aforementioned techniques to adjust the pressure). Adjusting the pressure according to the indication ensures that the user device can obtain multiple measurements at the same pressure.

[0050] In some aspects, the user device may provide an indication independent of the biometric operation. For example, the user device may provide an indication when the user device is attached to the user's body. Here, for example, the indication may indicate that the strap is to be tightened to a particular tightening, the longitudinal position of the user device on the user's body is to be adjusted, etc., to achieve a pressure within a range for obtaining data for the biometric. The user device may detect that the user device is being attached to the user's body based on detecting (e.g., using a gyroscope and / or accelerometer) movement of the attached user device.

[0051] As shown in reference numeral 420, the user device can detect whether the pressure at the interface between the user's body and the user device is within a range for obtaining data for biometrics. For example, the user device can detect whether the pressure is within the range based on monitoring the pressure. As described above, the user can adjust the pressure to within the range based on the instruction to perform one or more techniques to adjust the pressure.

[0052] like Figure 4CAs shown, and by reference numeral 425, the user device can obtain data for biometrics. For example, the user device can obtain data based on detecting that the pressure is within the range. In some aspects, the user device can obtain data based on providing an indication. That is, the user device can obtain data while providing an indication. In some aspects, the user device can use photoacoustic signal generation to obtain data. For example, the user device can emit a light signal at the user's body (e.g., using transmitter 310), which interacts with the user's body and generates sound waves. Continuing with this example, the user device can detect sound waves (e.g., using sensor 312), and the sound waves can provide data for biometrics. Additionally or alternatively, in order to obtain data, the user device can emit a light signal at the user's body and detect reflections of the light signal (e.g., in the case where reflection provides data), emit a sound signal at the user's body and detect reflections of the sound signal (e.g., in the case where reflection provides data), and / or emit an RF signal at the user's body and detect reflections of the RF signal (e.g., in the case where reflection provides data). In some aspects, the data may be indicative of a plethysmogram (eg, a photoplethysmogram (PPG) or a photoacoustic plethysmogram (PAPG)).

[0053] In some cases, when the user device is obtaining data, the pressure at the interface between the user's body and the user device may alternate between being within the range and being outside the range. For example, the data obtained for a biometric measurement may include first data for the biometric measurement obtained when the pressure is outside the range and second data for the biometric measurement obtained when the pressure is within the range. The user device may filter the data based on whether the data was obtained when the pressure was outside the range or when the pressure was within the range (which the user device may determine based on monitoring the pressure). Thus, the user device may discard the first data and retain the second data for further processing (e.g., for determining a biometric measurement based on the second data, regardless of the first data).

[0054] Additionally or alternatively, when the user device obtains data, the user device can adjust the intensity of the transmitted signal when the pressure at the interface between the user's body and the user device alternates between being within the range and being outside the range. That is, the user device can adjust the intensity of the transmitted signal based on the amount of pressure outside the range (the user device can be determined based on monitoring pressure). For example, in order to obtain data for biometrics, the user device can transmit an optical signal at the user's body, and the user device can adjust the intensity of the optical signal based on the amount of pressure outside the range. As an example, if the pressure is below the range, the user device can increase the intensity of the optical signal, and if the pressure is above the range, the user device can reduce the intensity of the optical signal. In this way, the data obtained by the user device is consistent across the pressure difference, and the acceptable range for obtaining data can be widened. In some aspects, in a similar manner to the above, the user device can adjust the intensity of the optical signal for optical-based data collection, the intensity of the acoustic signal for sound-based data collection, and / or the intensity of the RF signal for radio-based data collection.

[0055] As shown in reference numeral 430, the user device may determine the biometric based at least in part on the obtained data. For example, the user device may determine the biometric based solely on the data or based on a combination of the data with other data. The user device may determine the biometric by processing the data using one or more algorithms and / or one or more machine learning models. As described above, the biometric may be a blood pressure measurement, a heart rate measurement, a heart rate variability measurement, and / or a pulse oximetry measurement, among other examples.

[0056] In some aspects, another device (eg, wireless communication device 120) may determine a biometric based at least in part on data obtained by the user device. For example, the user device may send the data to the other device, and the other device may send information indicating the biometric to the user device.

[0057] The user device provides an indication of the biometric measurement to the user. In some aspects, the user device may present information indicating the biometric measurement in a user interface on a display of the user device. Additionally or alternatively, the user device may send a message (e.g., an email message) including the information indicating the biometric measurement. Additionally or alternatively, the user device may record the biometric measurement in a log or another data structure for subsequent retrieval by the user.

[0058] In this way, the user device can promote a relatively constant pressure at the interface between the user device and the user's body, thereby obtaining a relatively stable signal. Using this stable signal improves the accuracy of the biometric measurement, thereby reducing the number of measurements that need to be taken and saving resources of the user device.

[0059] As mentioned above, Figure 4A-4C are provided as examples. Other examples can be found in the Figure 4A-4C The examples described are different.
