An example electronic device may include a detection circuit and a processor operatively connected to the detection circuit. The processor may be configured to obtain a first signal associated with an external object through the detection circuit; obtain a first HR, using a first filter having an attribute of a first frequency band; obtain a second HR, using a second filter having an attribute of a second frequency band, based at least on the first signal; change at least some attributes associated with the second filter, based at least on the first HR and the second HR; obtain a second signal associated with the external object through the detection circuit; and generate heart rate variability (HRV) information, using the second filter, in which the at least some attributes are changed, based on the second signal.

Method for generating heart rate variability information related to external object by using plurality of filters, and device therefor

An electronic device according to various embodiments comprises: a bio-signal detection sensor configured to acquire first and second biometric information on an object outside the electronic device; and a processor, wherein the processor can be configured to: acquire the first and second biometric information by using the bio-signal detection sensor; configure a first variance, in which the first biometric information is changed, and a second variance, in which the second biometric information is changed; determining a state of the object related to the sleep on the basis of at least a part of the first variance and the second variance; and estimate a sleep latency related to the object on the basis of at least a part of the state.

Electronic device and method for determining sleep-related information
