1. A method of operating an electronic device, the method comprising:
- detecting a command for measuring specific biometric information;
in response to detecting the command, acquiring, using a biometric sensor of the electronic device, a first signal provided by a first light which is reflected through a user'"'"'s skin during a first time period, the first light corresponding infrared light;
identifying whether a contact state between the user'"'"'s skin and the biometric sensor is in a state capable of measuring the specific biometric information based on waveforms of the first signal during the first time period;
in response to the identifying that the contact state between the user'"'"'s skin and the biometric sensor is in the state capable of measuring the specific biometric information, acquiring, using the biometric sensor, a second signal provided by a second light which is reflected through the user'"'"'s skin during a second time period after the first time period, the second light corresponding at least one of visible light and infrared light for measuring the specific biometric information; and
identifying the specific biometric information based on the second signal,wherein the specific biometric information includes information related to a health state of the use, andwherein the detecting of the command comprises;
identifying, using a first sensor of the electronic device, the command by comparing a gesture with a preset gesture, anddriving the biometric sensor according to a result of the comparison.

Abstract
A method of operating an electronic device is provided. The method includes detecting a gesture through a first sensor module, acquiring first biometric information through a second sensor module in response to the gesture, determining whether a user'"'"'s skin contacts the second sensor module based on the first biometric information, and acquiring second biometric information from the user'"'"'s skin through the second sensor module according to a result of the determination.
