Abstract: The electronic device according to an embodiment includes: an input device; and a mobile device configured to communicate with the input device, wherein the mobile device determines a position of the mobile device or a position of a first external device as reference coordinates, receives relative position information of the input device, with respect to the reference coordinates, and motion information of the input device, determines a movement trajectory based on the relative position information and the motion information, and displays the movement trajectory or transmits the movement trajectory to a second external device.

Abstract: An electronic device is disclosed. The electronic device of the present disclosure comprises: a sensor; a communication unit; and a processor which receives first and second biosignals sensed at a first measurement part from the sensor, receives first and second biosignals sensed at a second measurement part from an external electronic device through the communication unit, synchronizes the second biosignal received from the sensor and the second biosignal received from the external electronic device on the basis of the first biosignal sensed at the first measurement part, and obtains a third biosignal on the basis of the synchronized second biosignals, wherein the rate at which the first biosignal propagates from a predetermined body organ is faster than the rate at which the second biological signal propagates.

Abstract: An electronic device is provided. The electronic device includes a first sensor configured to measure a physiological parameter of a user, a second sensor configured to measure motion feature of the user, at least one processor operatively connected with the first sensor or the second sensor, and a memory operatively connected with the at least one processor, wherein the memory stores instructions executed to enable the at least one processor to, monitor a physiological signal of the user based on the physiological parameter measured by the first sensor, upon detecting motion of the user using at least one of the first sensor or the second sensor while monitoring the physiological signal, identify a first signal indicating a physiological activity trend based on the motion feature obtained from the second sensor, and correct the physiological signal recorded for a first time period during which the motion is maintained based on the first signal.

Abstract: An electronic device and a method for obtaining a vital sign using the same are provided. The electronic device includes a memory to store instructions, and at least one processor connected to the memory. The instructions, which when executed, configure the at least one processor to receive a sensing signal related to a user's breathing from a sensor, obtain a first pattern related to a change in the respiration of the user over time, and a second pattern related to a change in saturation of peripheral oxygen of the user over time based on the sensing signal, and determine an oxygen delivery time (ODT), based on a comparison between the first pattern and the second pattern.
