Provided are an electronic device for selectively storing blood pressure information and updating calibration data on the basis of the stored blood pressure information, and a control method. The electronic device comprises, a memory operably connected with the processor, wherein the memory can include instructions, during the execution thereof, for allowing the processor to, display a user interface on a display, allow the user interface to provide guidelines for measuring the blood pressure, receive first data from the motion sensor, receive second data from a PPG sensor, receive third data from the PPG sensor, determine the validity of the third data at least partially on basis of the first data and the second data, and display an indication on the user interface at least partially basis of the determined validity.

Electronic device for updating calibration data on basis of blood pressure information, and control method

According to various embodiments, an electronic device may comprise: a housing comprising an inner space; a sensor structure positioned in the housing and exposed through a part of the housing, the sensor structure comprising a substantially transparent plate comprising a first surface facing away from the inner space and a second surface facing away from the first surface; a support structure positioned in the inner space so as to face the transparent plate; at least one light-emitting element mounted on the support structure while being spaced apart from the second surface and inserted between the second surface and the support structure; a spatial light modulator (SLM) disposed between the transparent plate and the LED while being spaced apart from the light-emitting element; a light-receiving element mounted on the support structure and positioned between the second surface and the support structure while being adjacent to a side surface of the light-emitting element; and a processing circuit comprising at least one electrical path electrically connected to the SLM, the processing circuit being operatively connected to the light-receiving element and configured to generate photoplethysmogram (PPG) data by using the light-emitting element. Other embodiments are possible.

Method for detecting biometric information by using spatial light modulator, electronic device, and storage medium

An electronic device is provided. The electronic device includes a housing, a touch screen display to be exposed through a first portion of the housing, a motion sensor disposed inside the housing, a photoplethysmography (PPG) sensor disposed in a second portion of the housing, a processor operatively coupled to the display, the motion sensor, and the PPG sensor, and a memory operably coupled to the processor. The memory stores instructions that allow, when executed, the processor to receive first data from the motion sensor, identify whether a user has started exercise based on at least a portion of the first data, receive second data from the PPG sensor after identifying whether or not the user has started exercise, and determine the type of exercise of the user based on at least a portion of the first data and the second data.

Electronic device for providing exercise information using biometric information and operating method thereof

An electronic device includes a processor and memory, wherein the memory stores instructions that, when executed by the processor, control the electronic device to: determine a pulse arrival time (PAT) value, a heart rate (HR) value, and a pulse transit time (PTT) value from the second data, calculate a first blood pressure value (BP1) and a second blood pressure value (BP2) by applying the determined values to pulse wave velocity (PWV) algorithms of Equations 1 and 2, wherein BP1&#x2245;aPAT+bHR+c. . . Equation 1, BP2&#x2245;aln(PTT)+b. . . Equation 2 in Equations 1 and 2, a, a, b, b, and care constant values for matching blood pressure values measured during calibration with blood pressure values measured by a cuff hemodynamometer, determine a calibration time point based at least in part on a difference between the first blood pressure value and the second blood pressure value, and provide guide information related to the calibration time point through a user interface based at least in part on the determination.
