Description

Device for providing image-based cardiovascular biometric information or user information based thereon, and method for providing the same

[0001] The present invention relates to an apparatus and a method for providing image-based cardiovascular bio-information or user information based thereon. More specifically, the invention relates to an apparatus and a method for providing a user’s rPPG (remote photoplethysmography) obtained from an image, the user’s cardiovascular bio-information obtained therefrom, or user information derived from the cardiovascular bio-information (e.g., user condition information) through an interface such as a display.

[0002] rPPG (remote photoplethysmography) refers to a technology that measures physiological signals, such as heart rate, in a non-contact manner. This technology is based on the principle of tracking blood flow by analyzing changes in light reflected from the skin.

[0003] Specific color changes (primarily in the green channel) are analyzed in images captured by a camera through the skin surface, and these color changes occur as the amount of blood in the skin changes with the heartbeat.

[0004] Sophisticated algorithms are used on captured image data to remove noise (movement, lighting changes, etc.) and extract periodic signals corresponding to blood flow.

[0005] rPPG offers high user convenience as it does not require sensors to be attached to the skin, and allows for various applications as measurements can be taken using smartphones, webcams, or CCTVs. Furthermore, it is safe and simple as it does not directly touch the body while measuring biosignals.

[0006] Therefore, recently, it is being used or applied in fields such as healthcare for health monitoring by measuring heart rate, blood pressure, and stress levels; fitness for analyzing heart rate and physical condition during exercise; and security monitoring and emotional state analysis by identifying stress or tension.

[0007] rPPG technology is continuously advancing and evolving into a system capable of more accurate and real-time applications when combined with artificial intelligence.

[0008] Figure 1 is a diagram illustrating the principle of heart rate detection using PPG (Photoplethysmography).

[0009] PPG is a non-invasive optical technology that is a method for acquiring physiological signals to measure the body's blood flow behaviors resulting from changes in blood volume. PPG is primarily based on the principle of detecting changes in reflected or transmitted light after irradiating the skin with infrared (IR) or visible light. Referring to Fig. 1, the process of acquiring an analog signal is illustrated in which a light source (LED) is irradiated toward the skin, and a photodetector (PD) detects light reflected from hemoglobin in the blood.

[0010] This utilizes the principle of detecting periodic changes in blood flow according to the heartbeat by utilizing the light absorption characteristics of blood.

[0011]

[0012] Meanwhile, while heart rate is a representative cardiovascular biometric information obtained from PPG or rPPG, the following biometric information in addition to heart rate may be included in the cardiovascular biometric information.

[0013] - Heart Rate Variability (HRV)

[0014] - Blood oxygen saturation (SpO₂)

[0015] - Respiratory Rate (RR)

[0016] - Pulse Wave Velocity (PWV)

[0017] - Blood Pressure (BP)

[0018] - Vascular Compliance & Volume Changes

[0019] - Stress Index

[0020] - Cardiac Output (CO)

[0021] Derived Cardiac Indices

[0022] - Macpa analysis-based indicators

[0023] In addition to the information listed above, fatigue index, circulatory health, blood pressure, etc., may be included in the cardiovascular bio-information obtained from PPG or rPPG.

[0024]

[0025] Figure 2 is a diagram illustrating the principle of rPPG. Basically, rPPG is the same as PPG, but differs in that it is non-contact. Referring to Figure 2, it can be seen that both the light source and the sensor (camera) are separated from the skin.

[0026] Similar to PPG, by monitoring components of external light that are absorbed and scattered within the skin and reflected to the camera (diffused reflection) in addition to components reflected from the skin surface, heart rate information caused by minute changes in blood flow on the skin surface can be detected.

[0027] Various cardiovascular biometric information can be estimated or obtained using rPPG extracted from an image of a user. This specification proposes a means for providing the user with the obtained cardiovascular biometric information or information for the user based thereon.

[0028] The present invention aims to provide a device and method for providing a user with cardiovascular bio-information obtained from an image or information for the user based thereon.

[0037] Additionally or alternatively, the operation may include matching the user's identification information with the cardiovascular biometric information or the body health index.

[0038] Additionally or alternatively, the above operation may include storing the cardiovascular bio-information or the body health index in the memory or a wired or wirelessly connected server.

[0039] Additionally or alternatively, the operation may include collecting the cardiovascular biometric information or the physical health index over time for individual users and generating pattern information for the collected cardiovascular biometric information or physical health index.

[0040] Additionally or alternatively, the operation may include estimating the cardiovascular bio-information or the body health index according to the generated pattern information.

[0041] Additionally or alternatively, the operation may include collecting the cardiovascular biometric information or the physical health index over time for an individual user, and outputting an alarm message to the display if the collected acquired cardiovascular biometric information or physical health index deteriorates over time.

[0042] Additionally or alternatively, the operation may include outputting to the display a user interface that guides a recommendation service corresponding to the cardiovascular bio-information or the body health index.

[0043] Additionally or alternatively, the above operation may include providing a recommendation service corresponding to the cardiovascular bio-information or the body health index.

[0044] Additionally or alternatively, the recommendation service may be determined based on the history information of the user's cardiovascular biometric information or physical health index and the corresponding service history information.

[0045] Additionally or alternatively, the device may further include a camera configured to photograph body parts including the user's face.

[0046] A method for outputting image-based cardiovascular bio-information or user information based thereon is proposed according to another embodiment of the present invention, wherein the method may include the steps of: obtaining a user’s cardiovascular bio-information estimated from an image of a body part including the user’s face, or obtaining a body health index based on said user’s cardiovascular bio-information; and outputting said cardiovascular bio-information or said body health index to a display.

[0047] In addition, a computer-readable medium is proposed that stores code configured to be executed by a computer or processor for a method to output image-based cardiovascular bio-information or user information based thereon according to another embodiment of the present invention.

[0072]

[0073] FIG. 3 shows a flowchart of a method for providing image-based cardiovascular bio-information or user information based thereon according to the present invention. The method illustrated in FIG. 3 may be performed by a device or processor thereof for providing image-based cardiovascular bio-information or user information based thereon. A description of a device for providing image-based cardiovascular bio-information or user information based thereon will be provided later with reference to FIG. 14. Hereinafter, it will be simply described that the device (10) performs an operation for providing image-based cardiovascular bio-information or user information based thereon.

[0074] The device (10) may be configured to identify a user (S310). This is to provide cardiovascular biometric information or user information based thereon to each user when the device (10) is available for use or access by multiple users. User identification may be performed through the processing of an image of the user, which may be included in an image for measuring the user's condition, which will be described later, or may be an image acquired separately.

[0075] When a user is identified, the device (10) may be configured to output the user's past or most recently acquired cardiovascular biometric information or user information based thereon through a display or a user interface on the display. Referring to FIG. 4, a user interface (1) according to one embodiment of the present invention is shown, in which the user's past or most recent cardiovascular biometric information (13, 14) and user information based thereon (i.e., physical health index) (12) are provided therein.

[0076] Additionally, the user interface (1) may include a message interface (11) for interaction with the user to induce the user to input commands to obtain and output cardiovascular bio-information or user information based thereon.

[0077] Additionally, the user interface (1) may include a message interface (18) for interaction with the user, and in FIG. 4, it is shown as being output in a manner that is overlaid on the user interface (16) for outputting the appearance of the user.

[0078] Additionally, the user interface (1) includes a user interface (15) for inputting user body information necessary to obtain cardiovascular bio-information or user information. When a user's touch input or other input is applied to the user interface (15), a user interface (151) for inputting user body information is displayed on a display, and FIG. 5 corresponds to an example thereof.

[0079] Additionally, the user interface (1) includes a user interface (16) for outputting the image of the user obtained through a camera.

[0080] Additionally, the user interface (1) includes an interface (17) for input control to initiate the acquisition of cardiovascular bio-information or user information. When a user's touch input or other input is applied to the interface (17), the acquisition of image-based cardiovascular bio-information or user information may be initiated.

[0081]

[0082] Returning to FIG. 3, the device (10) can be configured to acquire an image of the user and measure the user's condition from the acquired image (S320).

[0083] The acquired image may be a photograph of a body part including the user's face.

[0084] Additionally, in the present invention, the user's state measured from the acquired image may include the user's cardiovascular biometric information or a physical health index based on the user's cardiovascular biometric information. This may be information derived from rPPG acquired from the image. The physical health index acquired based on cardiovascular biometric information may be simply referred to as user information in this specification.

[0085] The device (10) may be configured to output the progress of the process of acquiring cardiovascular bio-information or the progress of the process of acquiring the body health index based on the user's cardiovascular bio-information to a display while acquiring the user's cardiovascular bio-information or acquiring the user's cardiovascular bio-information-based body health index. As an example, referring to FIGS. 4 and FIGS. 6, the user's real-time appearance may be displayed on the user interface (16), and a display interface (161) for displaying the progress may be set up and displayed around it. The device (10) may be configured to display the progress of the process of acquiring cardiovascular bio-information by filling the display interface (161) with a preset color, hatching, or pattern.

[0086] Additionally, time is required to acquire the user's cardiovascular biometric information or to acquire the user's cardiovascular biometric information-based physical health index. Accordingly, while acquiring the user's cardiovascular biometric information or the physical health index, the user's appearance may be displayed on the user interface (16), and the progress of the acquisition process described above may be displayed on the display interface (161).

[0087] Additionally, the device (10) may be configured to determine whether it is impossible to obtain the user's cardiovascular bio-information or the accuracy of the obtained cardiovascular bio-information based on the user's movement. If the user's movement makes it impossible to obtain the user's cardiovascular bio-information or if the accuracy of the obtained cardiovascular bio-information is lower than a threshold, the device (10) may be configured to output a warning to the user or a posture guide for the user on the display.

[0088] Additionally, the device (10) may be configured to acquire the user's condition at preset intervals. That is, the user's cardiovascular biometric information or a physical health index based on the user's cardiovascular biometric information may be acquired at preset intervals.

[0089] Additionally, the device (10) may be configured to use a preset number of image frames to acquire the user's cardiovascular biometric information or physical health index. For example, N image frames may be used to acquire the user's cardiovascular biometric information or physical health index (wherein N is an integer greater than or equal to 1). When multiple image frames are used to acquire the user's cardiovascular biometric information or physical health index, the multiple image frames may be non-continuous. For example, when a camera captures the user at 30fps, an image frame may be acquired every 1 / 30 sec, but the image acquired at 1 / 30 sec intervals is not necessarily used to acquire the user's cardiovascular biometric information or physical health index.

[0090] Additionally, the device (10) may be configured to acquire cardiovascular biometric information for multiple users or a body health index based on cardiovascular biometric information.

[0091] The device (10) may require a preset time to acquire the user's cardiovascular biometric information or physical health index. That is, a preset time may be required to acquire the user's cardiovascular biometric information or physical health index from an image.

[0092] In this case, the device (10) may be configured to process or analyze a plurality of image frames acquired during a preset time, and to stop the cardiovascular bio-information acquisition procedure if a user is not detected in a specific image frame.

[0093]

[0094] Additionally, the device (10) may be configured to match user identification information with the acquired user's cardiovascular biometric information or the acquired user's physical health index. Here, matching indicates linking the user identification information with the cardiovascular biometric information or the physical health index. That is, it is intended to specify or identify which user the acquired user's cardiovascular biometric information or the acquired user's physical health index belongs to.

[0095] Meanwhile, the device (10) may be configured to identify the user from the acquired image. That is, in this case, S310 and S320 may be integrated.

[0096] Meanwhile, the device (10) can acquire the user's cardiovascular biometric information or the user's physical health index on a per-user basis. Additionally, the device (10) can be configured to collect the user's cardiovascular biometric information or the user's physical health index over time. Referring to FIG. 7, the user's overall condition score, which is a type of physical health index over time, is shown. The device (10) can be configured to generate pattern information regarding the collected cardiovascular biometric information or physical health index.

[0097] For example, pattern information can be represented quantitatively as follows. This may be a value obtained by averaging the previously acquired physical health index values ​​by day of the week.

[0098] Day of the Week Overall Condition Score Sun 90 Mon 55 Tue 50 Wed 65 Thu 70 Fri 80 Sat 95

[0099] For example, pattern information can be represented quantitatively as follows. This may be a value obtained by averaging the previously acquired physical health index values ​​on a monthly basis.

[0100] Monthly Overall Condition Score Jan 45 Feb 55 Mar 65 Apr 65 May 70 Jun 80… …

[0101] Additionally, the device (10) may be configured to generate a message to guide the user to the generated pattern information and output it to a display or a user interface on the display.

[0102]

[0103] Additionally, the device (10) may be configured to estimate cardiovascular biometric information or a physical health index according to the generated pattern information. Accordingly, instead of performing image-based measurements of the user's state, the device (10) may provide an estimate of the current user's cardiovascular biometric information or physical health index. Alternatively, as illustrated in FIG. 8, the device (10) may be configured to output a message to a message interface (111) containing content based on the current user's cardiovascular biometric information or physical health index.

[0104] Additionally, the device (10) may be configured to generate trend information of the user's cardiovascular biometric information or physical health index using the user's cardiovascular biometric information or the user's physical health index collected over time. If the generated trend information indicates that the user's cardiovascular biometric information or physical health index is deteriorating over time, the device (10) may be configured to output an alarm message to a display or a user interface on the display. Additionally, if the generated trend information indicates that the user's cardiovascular biometric information or physical health index is improving over time, the device (10) may be configured to output an encouragement or congratulatory message to a display or a user interface on the display.

[0105]

[0106] The device (10) may be configured to output the results of the measured user state through a display or a user interface on the display (S330). That is, the device (10) may be configured to output the acquired user's cardiovascular bio-information or the acquired user's physical health index to a display or a user interface on the display, etc. Referring to FIG. 9, an example of a user interface according to an embodiment of the present invention is illustrated.

[0107] Referring to FIG. 9, the user interface (1) may include a message interface (11) for interaction with the user. Additionally, the user interface (1) may display a comparison display (141) of the acquired user's cardiovascular biometric information (13, 14) and the past or most recently acquired cardiovascular biometric information and the current cardiovascular biometric information, such as an arrow indicating whether it has improved or worsened, to the left of each individual piece of cardiovascular biometric information.

[0108] Additionally, the user interface (1) includes a user interface (16) for outputting the image of the user obtained through a camera.

[0109] Additionally, the user interface (1) includes an interface (171) for input control to restart the acquisition of cardiovascular bio-information or user information. Additionally, the user interface (1) includes an interface (172) for input control to terminate the acquisition of cardiovascular bio-information or user information. When a user's touch input or other input is applied to the interfaces (171, 172), the acquisition of image-based cardiovascular bio-information or user information may be restarted or terminated.

[0110] Additionally, the user interface (1) may include a message interface (19) for interaction with the user, and in FIG. 9, it is shown as being output in a manner that is overlaid on the user interface (16) for outputting the appearance of the user.

[0111] Additionally, the user interface (1) includes a user interface (15) for inputting user body information necessary to obtain cardiovascular bio-information or user information. When a user's touch input or other input is applied to the user interface (15), a user interface (151) for inputting user body information is displayed on a display, and FIG. 5 corresponds to an example thereof.

[0112]

[0113] Meanwhile, the device (10) may be configured to store the acquired cardiovascular bio-information or body health index in the memory of the device (10) or in a server connected to the device (10) via wired or wireless connection.

[0114]

[0115] The device (10) may be configured to output a suggestion to guide a recommendation service corresponding to the acquired cardiovascular bio-information or acquired user information (or physical health index) to a display or a user interface on the display (S340). Alternatively, the device (10) may be configured to automatically provide a recommendation service corresponding to the acquired cardiovascular bio-information or acquired user information (or physical health index).

[0116] In this specification, the recommendation service may include any one of the following: launching an app for the user, playing video or audio content, or changing the background image of the display of the user device. Additionally or alternatively, the recommendation service may include at least one contact in the address book stored on the user device or contacting at least one contact. Additionally or alternatively, the recommendation service may include displaying any one of the photos (images) stored on the user device or displaying them on a user interface on the display. Additionally or alternatively, the recommendation service may include displaying keywords or displaying them on a user interface on the display. Additionally or alternatively, the recommendation service may include physical activity for the user. For example, physical activity such as stretching, jogging, or walking may be included. Referring to FIG. 10, the user interface (1) includes a message interface (112) for suggesting rest to the user as a recommendation service.

[0117] Meanwhile, although a user device has been mentioned, in most embodiments, the user device may be integrated with the device (10), included in the device (10), or be an object equivalent to the device (10). For example, the user device may be a laptop computer, and the laptop computer or the processor mounted thereon may correspond to the aforementioned device (10).

[0118] Meanwhile, the recommendation service may be determined based on cardiovascular biometric information or physical health index previously acquired for the user, that is, historical information of the cardiovascular biometric information or physical health index. Alternatively, the recommendation service may be determined based on historical information of services executed by the user on the user's device. Alternatively, the recommendation service may be determined based on historical information of the user's cardiovascular biometric information or physical health index and historical information of the corresponding service.

[0119] For example, if the acquired user's cardiovascular biometric information or physical health index indicates fatigue, depression, etc., the recommendation service may be determined as one of the services executed on the user's device when vitality, enjoyment, etc. are indicated based on the user's past history.

[0120] Referring to FIG. 11, the user interface (1) includes a message interface (113) for suggesting the playback of video content to the user as a recommendation service. Additionally, the user interface (1) includes an interface (114) for displaying a list of video content.

[0121]

[0122] Meanwhile, the method for providing image-based cardiovascular bio-information or user information based thereon according to the present invention, as described with reference to FIG. 3, can be performed repeatedly. As a variation, referring to FIG. 12, the process returns to acquiring an image again and measuring the user's condition (S320) after S330 or S340. This corresponds to the feature described above where the user's cardiovascular bio-information is acquired at preset intervals.

[0123]

[0124] Meanwhile, the operation of the device (10) described above may be performed by executing code to output image-based cardiovascular bio-information or user information based thereon. In this case, the device (10) may include a memory configured to store code to output image-based cardiovascular bio-information or user information based thereon.

[0125]

[0126] FIG. 13 illustrates the transmission flow of image-based cardiovascular bio-information or user information based thereon according to another embodiment of the present invention.

[0127] The device (10) may be configured to transmit the user's cardiovascular biometric information or user information (or physical health index) measured or acquired by the device (10) to a server (30) connected via wired or wireless communication. Additionally, the server (30) may be configured to transmit the user's cardiovascular biometric information or user information (or physical health index) received from the device (10) to a third device (20) connected via wired or wireless communication.

[0128] The acquired user's cardiovascular biometric information or user information (or physical health index) is uploaded to the server (30) and can be downloaded from another device owned by the user, namely the third device (20). Through this, the user can access their cardiovascular biometric information or physical health index, etc., regardless of location or device, and can also measure, acquire, and store it.

[0129] The server (30) may include not only physical devices but also virtual devices.
