Description

Method of searching for a target device

The present invention relates to a search method, and more particularly to a method of searching for a target device.

With the development of personal mobile communications, users can communicate with each other through their mobile communication devices. The current mobile devices usually provide the ability to store contact information for the convenience of users to record and search for contact information. At present, some contact information has the location information of the contact person. When the user wants to search for the contact person, it is usually necessary to search for the contact person by entering the place name. However, when the user only wants to find a contact located within a certain distance around him or at a specific location, the current search by place name is not very convenient for the user. Therefore, there is a need for a more convenient way to find contacts.

The present invention provides a method of searching for a target device by which a user can search for a target device located at a certain orientation or distance by throwing a mobile electronic device. The present invention provides a more convenient search method for the user.

A method for searching for a target device includes receiving a first location information indicating a location of a first electronic device, receiving a plurality of second location information indicating a location of the plurality of second electronic devices, and displaying the first location information a corresponding location map of the correspondence between the location information and the second location information; detecting a change in location of the first electronic device to obtain a motion track And a set of preselected target devices selected from the second electronic device according to the motion trajectory.
