A portable terminal includes an apparatus for improving motion detection capability. More particularly, the apparatus improves motion detection capability by changing a motion in a normal state according to a motion state or by changing a motion detection process in the portable terminal in order to avoid motion detection capability deterioration in the portable terminal are provided. The apparatus includes a terminal state determiner that determines a motion state of the terminal by receiving sensing information for determining the motion state, and a controller that changes a motion detection process according to the portable terminal's motion state determined by the terminal state determiner.

Context recognition methods and apparatus are provided for an application processor and a micro control unit. It is determined whether an operation switch condition for switching to a sleep mode is satisfied. A request for execution of a context recognition function is sent to a micro control unit, when the operation switch condition is satisfied. The application processor switches to the sleep mode, when the context recognition function is executed by the micro control unit. The micro control unit collects sensor data at previously stored time intervals, and previously stored state information is updated based on the sensor data.

Provided is an apparatus and method for switching a navigation mode between a vehicle navigation mode and a personal navigation mode in a navigation device supporting vehicle navigation and personal navigation. Switching between the vehicle navigation mode and the personal navigation mode is performed according to whether the navigation device is mounted in a navigation device holder, whether a GPS speed provided by a GPS receiver is higher than a predetermined speed, and whether a step is detected using an output of an accelerometer. Since mode switching between the vehicle navigation mode and the personal navigation mode is automatically performed, a user does not need to manually perform mode switching.

A method of implementing a location-based service within a building is provided. The method includes receiving, from at least one electronic device, a plurality of data sets indicating information of wireless signals which the at least one electronic device measures for each time or for each location within the building; determining a similarity between the plurality of data sets; generating a logical path by integrating similar data sets; and generating a wireless signal map within the building by mapping the logical path to a physical path of the building.

A step detecting apparatus and method in a personal navigator where acceleration signals in at least two directions are acquired from an accelerometer sensor, as a pedestrian moves. Variances of the acceleration signals are calculated and summed. The variance sum is compared with a threshold. If the variance sum is greater than the threshold, it is determined that a detected step is a walking step. If the variance sum is less than the threshold, it is determined that the detected step is a mark-time step.
