Abstract: In a method for naming an electronic device, a hash table including indices and corresponding character strings is preset. The electronic device is controlled to enter into a searchable state, and inserts a default name of the electronic device in a searchable device list. A shaking angle of the electronic device is calculated according to detected coordinate values acquired from a gravity sensor, when the electronic device is shaking in the searchable state and the default name needs to be changed. A hash value is calculated using the shaking angle, a UNIX timestamp, a number of the indices in the hash table, and a predetermined formula. The method further determines an index that is the same as the hash value, determines a character string corresponding to the determined index, and renames the electronic device using the determined character string.

Abstract: In a method for motion detection of an electronic device, data on a touch screen of the electronic device is shared to a user. The method prevents the touch screen from being touched inadvertently when the electronic device is handed to or is picked up by the user. The method determines whether a movement of the electronic device is generated, wherein the movement is a motion generated when the electronic device is handed to the user. When the movement is generated, the method further locks a display of the touch screen, and determines whether the movement is finished. When the movement is finished, the method unlocks the display of the touch screen.

Abstract: In a method for displaying warning signals using an electronic device while riding a bicycle, the method firstly detects any acceleration of the electronic device in three predefined axes in real time using a gravity sensor of the electronic device, and detects any angular velocity of the electronic device around any of the three predefined axes using a gyroscope of the electronic device. Secondly, the method determines a current driving condition of the bicycle according to any detected acceleration and any detected angular velocity of the electronic device. The method displays warning signals on the display screen of the electronic device according to the current driving condition of the bicycle.
