Methods and apparatuses are provided for measuring a biometric signal by an electronic device. An object having an animation effect for inhalation and exhalation is displayed. The animation effect includes the object being expanded to guide the inhalation of a user and the object being contracted to guide exhalation of the user. A sensor unit obtains at least one biometric signal related to a heart rate of the user while the object is displayed. A motion of the electronic device is detected having a strength that is greater than or equal to a threshold strength. Based on the motion ceasing before exceeding a predetermined time, display of the object and obtaining of the at least one biometric signal is continued. Based on the motion lasting longer than or equal to the predetermined time, the obtaining of the at least one biometric signal and the displaying of the object is terminated.

Electronic device and method for measuring vital signal

A method includes obtaining, by a device and from a dynamic vision sensor (DVS), a set of images of an object that identifies that the object has moved. The method includes determining, by the device, that the object is associated with a predetermined posture based on the set of images. The method includes determining, by the device, a group to which the object belongs based on an attribute of the object and an attribute of the group. The method includes determining, by the device, whether the object is associated with the dangerous situation based on identifying that the object is associated with the predetermined posture and based on setting information associated with the group to which the object belongs.

Method and device for detecting dangerous situation

An apparatus for measuring blood pressure, and a method for measuring blood pressure by using the same are disclosed. The disclosed method for measuring blood pressure comprises the steps of: calculating pulse wave transit time; measuring vascular compliance; and measuring systolic blood pressure and diastolic blood pressure by using the pulse wave transit time and the vascular compliance, wherein the vascular compliance can be measured respectively in at least two or more different hand shape poses.

Apparatus for measuring blood pressure, and method for measuring blood pressure by using same

Methods and apparatuses are provided for measuring a vital signal. An application is executed to output vital information of a user wearing an electronic device. Instructions are output that guide inhalation and exhalation of the user based on the executed application. At least one vital signal for the user is obtained while outputting the instructions. Vital information corresponding to the obtained at least one vital signal is output.

An oxygen saturation measuring apparatus is provided. The oxygen saturation measuring apparatus includes a sensor configured to detect motion of the oxygen saturation measuring apparatus, a light emitter comprising light emitting circuitry configured to emit light to a target subject, a light receiver comprising light receiving circuitry configured to receive one or more of light reflected by the target subject or light transmitted through the target subject to generate a signal, and a processor configured to filter a frequency component corresponding to the detected motion in the signal, to detect a pulse frequency from the filtered signal, and to determine oxygen saturation of the target subject using the filtered signal and the detected pulse frequency.

Oxygen saturation measuring apparatus and oxygen saturation measuring method thereof

A device includes a first sensor to generate a movement signal of a user movement; a second sensor to generate a PPG signal of the user; and a processor configured to set each of time periods as a predetermined amount of time to determine one sleeping state of the user, set a first part of the predetermined amount of time in each time period to emit the light, and set a remaining part of the predetermined amount of time in each time period to not emit the light, control the light emitter of the second sensor to emit the light in the first part of each time period and to not emit the light in the remaining part of each time period, and determine, for each time period, the sleeping state of the user based on the movement signal and the PPG signal that are generated for each time period.

Electronic device and control method thereof

An electronic device includes: a first sensor configured to generate a movement signal corresponding to a user movement; a second sensor configured to physically contact the user to generate a user bio-signal; a processor configured to determine a user sleeping state using the generated movement signal and the generated user bio-signal in each of time periods, and determine an operation state of another electronic device based on the determined sleeping state in respective time periods; and a communicator configured to transmit a control command corresponding to the determined operation state to the another electronic device.

A physiological signal measurement apparatus includes a battery cover covering an area where a battery of a terminal device is detachably attached, a sensor unit detecting a physiological signal, the sensor unit being included in the battery cover, and a control unit controlling the sensor unit to detect the physiological signal, wherein the physiological signal measurement apparatus is detachably attached to the terminal device as the battery cover is detachably attached to the terminal device.

Method and apparatus for measuring bio signal

Disclosed is a method for an electronic device. The method may include: acquiring a galvanic skin response; generating a first parameter for a first interval and a second parameter for a second interval based on the galvanic skin response, the second interval being an interval before the first interval; determining a first threshold corresponding to the first interval based on the second parameter; and determining an activity state of the first interval based on the first threshold and the first parameter corresponding to the first interval.
