[0002] With the popularization of smart refrigerators, refrigerators with health detection functions are gradually entering users' lives. Currently, refrigerators with health detection functions mainly use contactless camera face detection and body contact detection. For devices that perform health detection through body contact, users usually cover the detection head with their fingers or other detection parts, and the health detection is carried out by detecting the light and other signals returned by the user.

[0003] However, when the user presses the detection area onto the detection head, there may be an offset between the detection area and the detection head, which may prevent the detection area from completely covering the entire detection area of ​​the detection head. The detection head is also susceptible to interference from external stray light, resulting in inaccurate health detection results. Summary of the Invention

[0047] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0048] The following is for reference. Figures 1-5 This application describes a biometric data acquisition device 100 and a storage device 500 according to embodiments of the present application.

[0049] The storage device 500 in this application embodiment can be understood as a refrigeration storage device in a broad sense, including but not limited to freezers, refrigerators, display cases, beverage cabinets, wine cabinets, refrigerated display cases, and refrigerated vending machines. The storage device 500 has diverse structural forms and a wide range of applications.

[0050] The biometric acquisition device 100 provided in this application embodiment is applied to storage equipment 500.

[0051] Among them, such as Figure 5As shown, the biometric acquisition device 100 can be installed on the outer surface of the storage device 500, or in a position on the cabinet door of the storage device 500 that is easily accessible to the user. For example, the biometric acquisition device 100 can be installed 1.5 meters above the ground on the storage device 500.

[0052] The biometric acquisition device 100 can be used to detect the user's biometrics, which may include blood pressure, blood oxygen, heart rate, and pulse.

[0053] In this embodiment, the biometric acquisition device 100 can be a closed structure, that is, the biometric acquisition device 100 can include a housing that defines a closed containment space.

[0054] like Figure 1 As shown, the biometric acquisition device 100 includes a first detection module 120, a second light receiver 130, and an interaction module, wherein the first detection module 120 and the second light receiver 130 can be disposed in the housing space of the biometric acquisition device 100.

[0055] In this embodiment, a collection window 110 may be provided on one side of the housing of the biometric collection device 100, and the collection window 110 may be a light-transmitting structure.

[0056] A light-transmitting material layer can be set on the outside of the acquisition window 110. The light-transmitting material layer is a transparent material with high light transmittance, such as glass with a light transmittance of 95% or higher. It can serve to improve aesthetics, prevent the user's target part 210 from directly contacting the biometric acquisition device 100, and reduce the weakening of light signals.

[0057] In this embodiment, the first detection module 120 includes a first light emitter 121, a second light emitter 122, and a first light receiver 123. The first light emitter 121 is used to emit light in a first band, the second light emitter 122 is used to emit light in a second band, and the first light receiver 123 is used to receive the first band light reflected from the user's target part 210 and determine the target position information of the target part 210 based on the reflected first band light.

[0058] The first light emitter 121 and the second light emitter 122 are components capable of emitting light. The first light emitter 121 and the second light emitter 122 emit light in different wavelengths; the first light emitter 121 emits light in a first wavelength band, and the second light emitter 122 emits light in a second wavelength band. There may be no overlap between the first and second wavelength bands. Both the first light emitter 121 and the second light emitter 122 can emit light towards the acquisition window 110. The first and second wavelength bands are between 500nm and 1000nm.

[0059] The user's target part 210 can be a part of the user's body, for example, the user's finger.

[0060] like Figure 2 As shown, the target part 210 can be placed on the outer surface of the acquisition window 110, the first detection module 120 and the second light receiver 130 can be set in the detection layer 220 in the accommodating space, and the first band light emitted by the first light emitter 121 and the second band light emitted by the second light emitter 122 can be directed toward the target part 210 and reflected by the target part 210.

[0061] In this embodiment, the first optical receiver 123 is a component that can receive light. The first optical receiver 123 can receive light of the first wavelength band. The first optical receiver 123 may be provided with a filter. The filter of the first optical receiver 123 can retain the light of the first wavelength band and filter out light of other wavelength bands.

[0062] The first band light reflected by the target part 210 can be received by the first optical receiver 123. The first optical receiver 123 can determine the target position information of the target part 210 based on the received first band light reflected by the target part 210. The target position information is used to characterize the position of the target part 210 relative to the acquisition window 110.

[0063] In this embodiment, the first optical receiver 123 can determine the target location information based on the duration of the received reflected first-band light. The longer the duration of the first optical receiver 123 receives the reflected first-band light, the greater the distance between the target part 210 and the acquisition window 110. The shorter the duration of the first optical receiver 123 receives the reflected first-band light, the smaller the distance between the target part 210 and the acquisition window 110.

[0064] In this embodiment, the second light receiver 130 is disposed on one side of the first detection module 120. The second light receiver 130 and the first detection module 120 are located within the acquisition window 110 of the biometric acquisition device 100. The second light receiver 130 is used to receive the second-band light reflected from the target part 210 and perform biometric detection based on the reflected second-band light.

[0065] The second light receiver 130 and the first detection module 120 are located within the acquisition window 110 of the biometric acquisition device 100, that is, the second light receiver 130 and the first detection module 120 are located in the accommodating space of the biometric acquisition device 100, and the second light receiver 130 does not block the light emitted by the first light emitter 121 and the second light emitter 122.

[0066] The second-band light emitted by the second light emitter 122 in the first detection module 120 can be directed toward the acquisition window 110, and the second light receiver 130 can receive the second-band light reflected from the target part 210 at the acquisition window 110.

[0067] In this embodiment, the second light receiver 130 can perform biometric detection based on the reflected second-band light.

[0068] When a user's heart beats, blood flows, causing changes in blood flow to the blood vessels in the skin of the target area 210, such as the fingers, which in turn causes changes in the amount of light absorbed. The second light receiver 130 can measure this change in light absorption and convert it into a photoplethysmography (PPG) signal to obtain biometrics.

[0069] The second light transmitter 122 emits short light pulses of the second band light and directs them toward the user's target area 210. When blood flows through the blood vessels, it causes slight vibrations in the blood vessel walls. The blood flow changes the absorption and reflection characteristics of the tissue to the second band light, reflecting part of the second band light to the second light receiver 130. The second light receiver 130 analyzes the changes in the received light signal to obtain biological characteristics such as blood pressure and heart rate.

[0070] It is understandable that when the target area 210 cannot completely cover the acquisition window 110, external stray light may interfere with the second-band light, resulting in inaccurate biometric detection results.

[0071] In this embodiment, the biometric acquisition device 100 is further provided with an interaction module, which is connected to the first detection module 120 and the second light receiver 130.

[0072] In this embodiment, the first optical receiver 123 is used to send an instruction to the interaction module to output interactive information based on the target position information. When the first optical receiver 123 determines that the target part 210 is deviating from the acquisition window 110 based on the target position information, it can send an instruction to the interaction module to output information to adjust the position of the target part 210 relative to the acquisition window 110.

[0073] When the target area 210 does not deviate from the acquisition window 110, the second light receiver 130 can perform biometric detection based on the reflected second-band light, and the interaction module can output the biometric detection results to the user.

[0074] According to the biometric acquisition device 100 provided in the embodiments of this application, a first light transmitter 121 emits first-band light, and a first light receiver 123 receives the first-band light reflected from the user's target part 210. Based on the reflected first-band light, the target position information of the target part 210 is determined. The interaction module can output interaction information based on the target position information. When the target part 210 deviates from the acquisition window 110, the user is prompted to adjust the position of the target part 210, thereby reducing the interference of external stray light on biometric acquisition and improving the detection accuracy of biometrics.

[0075] In some embodiments, the first light emitter 121 includes a plurality of first sub-light emitters 121a, and the second light emitter 122 includes a plurality of second sub-light emitters 122a, wherein the positions of the plurality of first sub-light emitters 121a and the positions of the plurality of second sub-light emitters 122a correspond one-to-one.

[0076] Multiple first sub-light transmitters 121a are used to emit multiple first band lights at different positions. A first light receiver 123 is used to receive the first band lights reflected from multiple target positions of the target part 210 and determine the target position information based on the reflected multiple first band lights. The first band lights reflected from multiple target positions correspond one-to-one with the first band lights emitted by the multiple first sub-light transmitters 121a.

[0077] Multiple second sub-light emitters 122a are used to emit multiple second-band lights at different locations, and a second light receiver 130 is used to receive the second-band lights reflected from multiple target locations and perform biometric detection based on the reflected multiple second-band lights. The second-band lights reflected from multiple target locations correspond one-to-one with the second-band lights emitted by the multiple second sub-light emitters 122a.

[0078] The first sub-light emitter 121a is a component capable of emitting light in the first wavelength band, and the second sub-light emitter 122a is a component capable of emitting light in the second wavelength band.

[0079] like Figure 3 As shown, multiple first sub-light emitters 121a and multiple second sub-light emitters 122a can be arranged into an array, with one position in the array corresponding to one first sub-light emitter 121a and one second sub-light emitter 122a.

[0080] In this embodiment, multiple first sub-light emitters 121a are used to emit multiple first band light at different positions, that is, each first sub-light emitter 121a is located at a different position and each first sub-light emitter 121a emits first band light.

[0081] In this embodiment, the target position of the target part 210 is the position in the target part 210 that is illuminated by the first band light. Each target position can reflect the first band light, and the first light receiver 123 can receive the first band light reflected from each target position.

[0082] The first optical receiver 123 may include multiple first sub-optical receivers, and the multiple first sub-optical receivers correspond one-to-one with multiple first sub-optical transmitters 121a. The first sub-optical receiver can receive the first band light reflected from the target position emitted by the corresponding first sub-optical transmitter 121a.

[0083] In this embodiment, the first sub-optical receiver can be located at the same position as the first sub-optical transmitter 121a.

[0084] In this embodiment, the first optical receiver 123 can determine the distance of the target position relative to the corresponding position of the target position in the acquisition window 110 based on the first band light reflected from the target position. The target position information includes the distance of each target position relative to the corresponding position in the acquisition window 110.

[0085] When the target position covers the corresponding position of the target position in the acquisition window 110, there is no offset between the target position and the acquisition window 110.

[0086] In this embodiment, multiple second sub-light emitters 122a are used to emit multiple second-band light at different locations, that is, each second sub-light emitter 122a is located at a different location and emits second-band light.

[0087] In this embodiment, the second band light emitted by the second sub-light emitter 122a and the first band light emitted by the corresponding first sub-light emitter 121a can illuminate the same target location.

[0088] In this embodiment, the second optical receiver 130 generates a detection signal based on the reflected multiple second-band light, and performs biometric detection based on the generated detection signal.

[0089] In this embodiment, the target location information includes the distance of each target location relative to the corresponding position of the target location in the acquisition window 110. The interaction module can determine whether each target location deviates from the corresponding position of the target location in the acquisition window 110 based on the target location information, and output the corresponding interaction information to prompt the user to adjust the target part 210 to ensure that external stray light does not enter the acquisition window 110 and reduce the interference of biometric detection.

[0090] In some embodiments, the interaction module is configured to output interactive information for adjusting the position of a portion of the target when it is determined, based on the target position information, that the distance between a portion of the target position and the acquisition window 110 is greater than a deviation distance threshold.

[0091] The deviation distance threshold is a preset value. When the distance between the target position and the acquisition window 110 is greater than the deviation distance threshold, stray light may exist at the target position, affecting the detection results.

[0092] In this embodiment, when the distance between a part of the target position and its corresponding position in the acquisition window 110 is greater than the deviation distance threshold, the interaction module can output interactive information to adjust the part of the target position, instructing the user to adjust the target position so that the target position covers the corresponding position of the target position in the acquisition window 110.

[0093] In some embodiments, the interaction module is configured to output interaction information for repositioning the target part 210 when it is determined, based on the target location information, that the distance of all target positions from the acquisition window 110 is greater than the deviation distance threshold.

[0094] In this embodiment, when the distance between all target positions and their corresponding positions in the acquisition window 110 is greater than the deviation distance threshold, it indicates that the entire target part 210 is significantly deviated from the acquisition window 110. The interaction module can output interactive information to reposition the target part 210, instructing the user to reposition the target part 210.

[0095] Understandably, when the distance between all target locations and their corresponding locations in the acquisition window 110 is less than the deviation distance threshold, it indicates that there is no deviation between the target location 210 and the acquisition window 110. The second light emitter 122 emits second-band light towards the target location 210, and the second light receiver 130 receives the second-band light reflected from the target location 210 for biometric detection. During the biometric detection process, if the distance between the target location and its corresponding location in the acquisition window 110 is detected to be greater than the deviation distance threshold, the detection can be paused, and the user can be prompted to adjust the target location 210 until there is no deviation between the target location 210 and the acquisition window 110, and then the detection can be restarted.

[0096] In this embodiment, the second light receiver 130 can perform biometric detection based on the reflected second-band light.

[0097] In some embodiments, a light-shielding device is provided between the first light emitter 121 and the second light emitter 122.

[0098] The light-shielding device is an opaque device. A light-shielding device is provided between the first light emitter 121 and the second light emitter 122. There is no interference between the first band light emitted by the first light emitter 121 and the second band light emitted by the second light emitter 122.

[0099] In some embodiments, the first band of light is infrared light, and the second band of light is visible light.

[0100] The first band is approximately 940nm. Infrared light at 940nm has moderate energy and relatively weak penetration, so it will not cause harm to the human body. At the same time, the signal attenuation is small, and the measured target location information is accurate.

[0101] This application also provides a storage device 500.

[0102] like Figure 5 As shown, the storage device 500 includes the aforementioned biometric acquisition device 100 and display screen 510.

[0103] The display screen 510 is connected to the biometric acquisition device 100. The display screen 510 is used to receive interactive information output by the interactive module and output prompt information based on the interactive information. The prompt information is used to indicate the deviation between the target part 210 and the acquisition window 110.

[0104] In this embodiment, when the display screen 510 determines, based on the interactive information output by the interactive module, that the target part 210 deviates from the acquisition window 110, i.e., there is a deviation between the target part 210 and the acquisition window 110, it outputs a prompt message indicating the deviation between the target part 210 and the acquisition window 110.

[0105] According to the storage device 500 provided in the embodiments of this application, a first light transmitter 121 emits first-band light, and a first light receiver 123 receives the first-band light reflected from the user's target part 210. Based on the reflected first-band light, the target position information of the target part 210 is determined. The interaction module can output interaction information based on the target position information. When the target part 210 deviates from the acquisition window 110, the user is prompted to adjust the position of the target part 210, thereby reducing the interference of external stray light on biometric acquisition and improving the accuracy of biometric detection.

[0106] In some embodiments, the display screen 510 is configured to output a first prompt message upon receiving interactive information indicating that the target position is being adjusted.

[0107] The first prompt information is used to indicate that the position of the target part 210 deviates from the corresponding position of the target part 210 in the first direction compared with the first direction of the acquisition window 110. The first direction is the direction corresponding to the partial target position.

[0108] In this embodiment, the display screen 510 receives interactive information to adjust the position of a partial target, indicating that the position of the partial target is deviated from the corresponding position of the target position in the acquisition window 110. The display screen 510 outputs a first prompt message to prompt the user to adjust the position of the target part 210 in the first direction.

[0109] In some embodiments, the first prompt information includes displaying a first graphic on the interactive interface of the display screen 510, wherein the style of the first graphic in a sub-region corresponding to a first position is different from the style of the first graphic in a sub-region corresponding to another position.

[0110] The interactive interface is a virtual interface displayed on the display screen 510. The first graphic can be a simulated graphic corresponding to the contact acquisition window 110 of the target part 210. Each position in the first graphic can correspond to each position of the contact acquisition window 110 of the target part 210.

[0111] In this embodiment, the style of the sub-region corresponding to the first graphic in the first position is different from the style of the sub-region corresponding to the first graphic in other positions. That is, the style of the sub-region corresponding to the target position that has deviation in the first graphic is different from the style of the sub-region corresponding to the target position that has no deviation in the first graphic.

[0112] The style can be color, brightness, and fill pattern, for example, the first graphic in the first position corresponds to a red sub-region, and the first graphic in other positions corresponds to a white sub-region.

[0113] like Figure 4 As shown, the first graphic has a striped pattern filling in the sub-region corresponding to the upper left corner, while the first graphic has no filling in the sub-region corresponding to other positions. This indicates that the position of the target part 210 deviates from the corresponding position of the target part 210 in the upper left corner compared to the position of the target part 210 in the acquisition window 110.

[0114] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0115] This application embodiment also provides an interaction method for a storage device 500, which is used in the aforementioned storage device 500.

[0116] The following description, in conjunction with the accompanying drawings, details the interaction method, interaction device, electronic device, and readable storage medium of the storage device 500 provided in this application, through specific embodiments and application scenarios.

[0117] The interaction method of the storage device 500 can be applied to the terminal, and can be executed by the hardware or software in the terminal.

[0118] The terminal includes, but is not limited to, portable communication devices such as mobile phones or tablets with touch-sensitive surfaces (e.g., touchscreen displays and / or touchpads). It should also be understood that, in some embodiments, the terminal may not be a portable communication device, but rather a desktop computer with touch-sensitive surfaces (e.g., touchscreen displays and / or touchpads).

[0119] The following embodiments describe a terminal including a display and a touch-sensitive surface. However, it should be understood that the terminal may include one or more other physical user interface devices such as a physical keyboard, mouse, and joystick.

[0120] The interaction method of the storage device 500 provided in this application embodiment can be executed by an electronic device or a functional module or functional entity in an electronic device that can implement the interaction method of the storage device 500. The electronic devices mentioned in this application embodiment include, but are not limited to, mobile phones, tablets, computers, cameras and wearable devices. The interaction method of the storage device 500 provided in this application embodiment will be described below with an electronic device as the execution subject.

[0121] like Figure 6 As shown, the interaction method of the storage device 500 includes steps 610 and 620.

[0122] Step 610: Receive the first input from the user's contact with the biometric data acquisition device 100.

[0123] In this step, the first input is used to activate the biometric acquisition device 100. Once activated, the user touches the biometric acquisition device 100, which can detect the user's biometric features.

[0124] The first input can be in at least one of the following ways:

[0125] Firstly, the first input can be a touch operation, including but not limited to click, swipe, and press operations.

[0126] In this embodiment, receiving the user's first input can be receiving the user's touch operation on the display area of ​​the terminal display screen 510.

[0127] To reduce the rate of user error, the effective area of ​​the first input can be limited to a specific area, such as the upper middle area of ​​the interactive interface; or, while the interactive interface is displayed, the target control can be displayed on the current interface, and touching the target control will enable the first input; or the first input can be set to a series of taps on the display area within a target time interval.

[0128] Secondly, the first input can be a physical button input.

[0129] In this embodiment, the terminal is equipped with a physical button on its body that corresponds to activating the biometric data collection device 100. The first input received by the user can be the user pressing the corresponding physical button; the first input can also be a combination of pressing multiple physical buttons simultaneously.

[0130] Thirdly, the first input can be voice input.

[0131] In this embodiment, the terminal can activate the biometric acquisition device 100 when it receives a voice message such as "Activate biometric acquisition device 100".

[0132] Fourth, the first input can be to bring the target part 210 into contact with the acquisition window 110.

[0133] In this embodiment, the user can trigger the activation of the biometric data acquisition device 100 by placing the target part 210, such as a finger, on the acquisition window 110.

[0134] Of course, in other embodiments, the first input may also be in other forms, including but not limited to character input, etc., which can be determined according to actual needs, and this application embodiment does not limit it.

[0135] Step 620: In response to the first input, output the first prompt message on the interactive interface.

[0136] The first prompt information is used to indicate that the position of the target part 210 deviates from the corresponding position of the target part 210 in the first direction compared with the first direction of the acquisition window 110. The first direction is the direction corresponding to the partial target position.

[0137] In this embodiment, in response to the first input, after the biometric acquisition device 100 is turned on, the first light emitter 121 can emit light of the first wavelength, and the second light emitter 122 can emit light of the second wavelength. The first wavelength light and the second wavelength light can be directed toward the target part 210 and reflected by the target part 210.

[0138] The first band light reflected by the target part 210 can be received by the first optical receiver 123, and the first optical receiver 123 can determine the target position information of the target part 210 based on the received first band light reflected by the target part 210.

[0139] In this embodiment, if it is determined that there is a deviation between the target position and the corresponding position of the target position in the acquisition window 110 based on the target position information, the first prompt message is output on the interactive interface of the display screen 510 to prompt the user to adjust the position of the target part 210 in the first direction.

[0140] According to the interaction method of the storage device 500 provided in the embodiments of this application, a first light transmitter 121 emits a first band light, and a first light receiver 123 receives the first band light reflected from the user's target part 210. Based on the reflected first band light, the target position information of the target part 210 is determined. The interaction module can output interaction information based on the target position information. When the target part 210 deviates from the acquisition window 110, the user is prompted to adjust the position of the target part 210, thereby reducing the interference of external stray light on biometric acquisition and improving the detection accuracy of biometrics.

[0141] In some embodiments, the first prompt message is output on the interactive interface, including:

[0142] The first graphic is displayed on the interactive interface. The style of the first graphic in the sub-region corresponding to the first position is different from the style of the first graphic in the sub-region corresponding to other positions.

[0143] The interactive interface is a virtual interface displayed on the display screen 510. The first graphic can be a simulated graphic corresponding to the contact acquisition window 110 of the target part 210. Each position in the first graphic can correspond to each position of the contact acquisition window 110 of the target part 210.

[0144] In this embodiment, the style of the sub-region corresponding to the first graphic in the first position is different from the style of the sub-region corresponding to the first graphic in other positions. That is, the style of the sub-region corresponding to the target position that has deviation in the first graphic is different from the style of the sub-region corresponding to the target position that has no deviation in the first graphic.

[0145] The style can be color and brightness, for example, the first graphic in the first position corresponds to red in the sub-region, and the first graphic in other positions corresponds to white in the sub-region.

[0146] The interaction method of the storage device 500 provided in this application embodiment can be executed by the interaction device of the storage device 500. This application embodiment uses the interaction device of the storage device 500 executing the interaction method of the storage device 500 as an example to illustrate the interaction device of the storage device 500 provided in this application embodiment.

[0150] The receiving module 710 is used to receive the first input from the user's contact with the biometric data acquisition device 100;

[0151] The processing module 720 is used to respond to the first input and output the first prompt information on the interactive interface. The first prompt information is used to indicate that the position of the target part 210 deviates from the corresponding position of the target part 210 in the first direction compared with the corresponding position of the target part 210 in the acquisition window 110. The first direction is the direction corresponding to the partial target position.

[0152] According to the interactive device of the storage device 500 provided in the embodiments of this application, a first light transmitter 121 emits a first band of light, and a first light receiver 123 receives the first band of light reflected from the user's target part 210. Based on the reflected first band of light, the target position information of the target part 210 is determined. The interactive module can output interactive information based on the target position information. When the target part 210 deviates from the acquisition window 110, the user is prompted to adjust the position of the target part 210, thereby reducing the interference of external stray light on biometric acquisition and improving the accuracy of biometric detection.
