Abstract: Location-based associated data management methods and systems are provided. First, first data corresponding to a first location is provided in an electronic device. Then, a current location of the electronic device is obtained via a positioning unit of the electronic device. When the current location of the electronic device and the first location are not the same, second data corresponding to the current location for the first data is received by a network connecting unit via a network.

Abstract: Methods and systems for displaying data for use in an electronic device are provided. First, an image corresponding to at least one specific object is captured by an image capture unit. When the distance between the electronic device and the specific object has changed or the presentation manner of the specific object in the display unit has changed, first data is displayed via the display unit.

Abstract: Coverage area-centric data transmission systems and methods are provided. First, the location of an electronic device is obtained, and a coverage area parameter is received. A data transmission coverage area is defined according to the location of the electronic device and the coverage area parameter. Then, specific data corresponding to the electronic device is transmitted to at least one candidate electronic device within the data transmission coverage area.

Abstract: Methods and systems for providing data between electronic devices are provided. First, a first electronic device outputs a first signal to an environment. A second electronic device receives a second signal from the environment via an environment data obtaining unit. In some embodiments, the first signal and the second signal are respectively transmitted to a server via a network. In other embodiments, the second signal is transmitted to the first electronic device. The server or the first electronic device determines whether the second signal conforms to the first signal. If so, specific data corresponding to the first electronic device is provided to the second electronic device. In some embodiments, when the signals received by several electronic devices conform to the first signal, data corresponding to the respective electronic devices is exchanged.
