Abstract: A electronic device and method are disclosed herein. The electronic device includes a display, a fingerprint recognition sensor configured to recognize a fingerprint received through the display, and a processor. The processor is configured to implement the method, which includes detecting a fingerprint using a fingerprint recognition sensor of the electronic device through a display of the electronic device; and controlling the display to display at least one object based on the fingerprint.

Abstract: A method for position measurement of a portable electronic device is provided.

Abstract: A method of operating an electronic device is provided. The method includes detecting a plurality of fingerprint drags after a touch on a portion of the electronic device, wherein each of the plurality of fingerprint drags is a consecutive drag from a previous drag and each of the plurality of fingerprint drags has a different orientation from each other; and identifying a fingerprint based on a plurality of images acquired from the plurality of fingerprint drags, wherein each of the plurality of images is compared with corresponding portion of a reference image.

Abstract: A method for operating an electronic device including a first sensor is provided, the method including: obtaining a first reading from the first sensor; detecting a state of the electronic device; and adjusting the first reading based on the state the electronic device to generate an adjusted reading; and performing, by the electronic device, an action based on the adjusted reading; wherein the first sensor includes at least one of a temperature sensor and a humidity sensor.

Abstract: An apparatus and a method for measuring an altitude of a terminal which can correct an altitude error according to temporal and spatial changes are provided. The apparatus includes an atmospheric pressure measuring unit for measuring an atmospheric pressure from a barometer included in the terminal, a position determiner for measuring position information of the terminal, and a controller for, when a reference atmospheric pressure reception period is not generated, predicting a current reference atmospheric pressure by using previously received reference atmospheric pressures and measuring a current altitude by using the predicted reference atmospheric pressure and the measured atmospheric pressure.

Abstract: A method for position measurement of a portable electronic device is provided.

Abstract: A multimedia service system includes a portable terminal that communicates with a server. When a portable terminal is located at or within a building, the portable terminal acquires floor information of the building from a server, calculates a present altitude itself, determines a floor corresponding to the calculated altitude from the floor information, receives a multimedia service for the detected floor from the server, and outputs the received multimedia service. The server provides altitude-by-altitude floor information of the building and a floor-by-floor multimedia service to the portable terminal.

Abstract: An apparatus for acquiring a position of a portable terminal includes a position estimating unit for estimating a position of a portable terminal based on prestored reference information, and a control unit for detecting—the position of the portable terminal using information from a server, wherein when there is a failure to acquire the position information of the portable terminal using the information from the server, the position estimating unit acquires the position of the portable terminal based on the estimated position of the portable terminal.

Abstract: An apparatus and method for location estimation in a portable terminal are provided. An operation of the portable terminal includes, if a location estimation function is activated, determining whether a reference location corresponding to a cell IDentifier (ID) of a currently connected cell is prestored, determining a search frequency range of a Global Positioning System (GPS) signal using the stored reference location, and estimating a location of the portable terminal using the GPS signal detected in the search frequency range.

Abstract: A method of improving the reception performance of a network-aided GPS (Global Positioning System) receiver is disclosed. It is determined whether the present time is feasible for TLM/HOW coherent integration, based on present CDMA/GPS information. When the TLM/HOW coherent integration is immediately available, a GPS signal acquisition search is performed using the TLM/HOW coherent integration. Then, it is determined whether the signal acquisition search is successful. If the signal acquisition search has failed, then there is a request for navigation data bits to a base station, which increases a coherent integration period.
