According to an embodiment of the present disclosure, there is a wearable electronic device, comprising: a first sensor configured to sense a movement of the electronic device; a second sensor configured to sense a biological signal for a user wearing the electronic device; and a processor configured to compute a movement value of the electronic device using the first sensor, to detect a resting state when the movement value lasts within a predetermined first threshold range during a first time period, and to configure biological information of the user based on a biological signal measured after detection of the resting state.

Method for measuring biological signal and wearable electronic device for the same

A method and apparatus for detecting location information using a navigation algorithm are provided. The method includes searching for neighboring Global Positioning System (GPS) satellites, receiving, if at least one GPS satellite is detected, pseudo-range information from at least one of the detected GPS satellites and storing the received pseudo-range information, calculating a displacement of a pedestrian terminal based on step detection of a pedestrian, correcting the calculated displacement of the pedestrian terminal using the received pseudo-range information, and measuring the location of the pedestrian terminal is measured using the corrected displacement.

Apparatus and method for detecting location information using navigation algorithm

A method and apparatus of a portable terminal estimate a step length of a pedestrian. An accelerometer detects acceleration caused by a movement of the portable terminal as a pedestrian carrying the portable terminal walks. A gyroscope detects angular velocity caused by the movement of the portable terminal as the pedestrian walks. A controller determines a magnitude of a swinging motion of the portable terminal by using at least one of the detected acceleration and angular velocity, determines that the portable terminal makes the swinging motion when the magnitude of the swinging motion is equal to or greater than a predetermined value, determines a carrying position of the portable terminal in the pedestrian's body by using at least one of the detected acceleration and angular velocity, and estimates a step length of the pedestrian according to the determined carrying position of the portable terminal.
