Apparatus and method for determining calibration timing for blood pressure measurement in electronic device
An electronic device includes a sensor, a memory, and a display, and a processor. The processor is configured to determine bio-information and blood pressure information of a user measured through the sensor, determine reliability of calibration of the blood pressure information, based on at least one of elapsed time of the calibration, the bio-information, and the blood pressure information, determine, based on the reliability of the calibration, whether an event associated with the calibration occurs, and display a user interface (UI) to request another calibration, through the display, when the event is determined to have occurred.
1. An electronic device comprising:
a sensor;
a memory;
a display; and
a processor,
wherein the processor is configured to:
determine bio-information and blood pressure information of a user measured through the sensor;
determine reliability of a first calibration of the blood pressure information, based on at least one of elapsed time of the first calibration, the bio-information, and the blood pressure information;
determine, based on the reliability of the first calibration, whether an event associated with the first calibration occurs;
display a user interface (UI) to request a second calibration, through the display, when the event is determined to have occurred,
display a place information associated with the second calibration on a city scale if the reliability of the first calibration is in a higher stage,
display the place information on a neighborhood scale if the reliability of the first calibration is in an intermediate stage, and
display a closest place from the electronic device associated with the second calibration or display a path from a current location of the electronic device to the closest place if the reliability of the first calibration is in a lower stage or if an expiration time point has come to pass,
wherein the expiration time point is a point when the reliability of the first calibration becomes zero.
2. The electronic device of claim 1 , wherein the processor is further configured to:
display the UI to request the second calibration through the display, when the reliability of the first calibration is less than a specified threshold value.
3. The electronic device of claim 2 , wherein the specified threshold value includes a plurality of threshold values, and
wherein the processor is further configured to:
set the plurality of threshold values based on the reliability of the first calibration.
4. The electronic device of claim 1 , wherein the processor is further configured to:
determine the expiration time point of the first calibration, based on the reliability of the first calibration; and
display the UI to request the second calibration through the display, when the expiration time point of the first calibration comes to pass.
5. The electronic device of claim 1 , further comprising:
a communication module,
wherein the processor is further configured to:
measure a location of the electronic device through the communication module;
transmit information on the measured location to an external electronic device;
receive the place information related to the second calibration from the external electronic device; and
display the received place information through the display.
6. The electronic device of claim 5 , wherein the processor is further configured to:
set a radius for displaying the place information based on the reliability of the first calibration.

display, through the display, the blood pressure information of the user with a reliability section for representing the reliability; and
change a color, brightness, and/or a size of the reliability section based on the reliability.
9. The electronic device of claim 1 , wherein the reliability of the first calibration is expressed through Equation 1,
R i =R i-1 −( w 1 Δt+w 2 Δbio-info+ w 3 ΔBPV )+ b ,and Equation 1
wherein R i refers to a reliability of a present calibration, R i-1 refers to a reliability of a previous calibration, Δt refers to a difference between a first time point corresponding to R i-1 and a second time point corresponding to R i , w 1 refers to a weight applied to Δt, Δbio-info refers to a variation in the bio-information, w 2 refers to a weight applied to the Δbio-info, ΔBPV refers to a variation in the blood pressure information, w 3 refers to a weight applied to the ΔBPV, and b refers to a bias.
