Abstract: The present invention provides a method for selecting a response, an earphone base, a method of selecting a wireless earphone, a device and a medium. The method for selecting a response includes sending communication data to a user terminal, the communication data comprises a wireless earphone communication data and/or an earphone base communication data; detecting whether a selection command for the wireless earphone sent from the user terminal is received; and controlling the earphone base corresponding to the selection command to execute a predetermined response action. By adopting the present invention, the earphone base establishes a connection with the user terminal through its own communication function or a connected wireless earphone. The communication data of the earphone base and the wireless earphone are sent to the user terminal for the user to view. The earphone base is capable of responding when receiving the selection command.

Abstract: An input method for an electronic device comprises steps of retrieving operation data according to a touch point made by a user on an input interface; generating a pending input pattern in response to the operation data of the touch point; retrieving a matched character corresponding to the pending input pattern, in response to a defined mapping relation of a plurality of input patterns and a plurality of characters; outputting the matched character.

Abstract: A computer mouse includes at least one first fingerprint recognition device disposed on an outside surface of the computer mouse, and configured to recognize fingerprint data; and an output converting unit connected to the first fingerprint recognition device, wherein a mapping relation of a plurality of fingerprint data and a plurality of output characters is pre-stored in the output converting unit, and one of the output characters is outputted, by the output converting unit, in response to the received fingerprint data coming from the first fingerprint recognition device.

Abstract: A positioning system includes a radio frequency (RF) device, a microphone array, and a calculation device. The RF device is configured to transmit an RF signal to an external device for pairing with the external device. The microphone array is configured to receive an audio signal transmitted from the external device after the positioning system is paired with the external device. The calculation device is configured to calculate a direction from the positioning device to the external device based on a time interval of the audio signal received by the microphone array, and configured to calculate a distance between the positioning system and the external device based on the audio signal transmitted by the external device after pairing. The calculation device is configured to position a location of the external device according to the direction and the distance.

Abstract: An unmanned vehicle includes a vehicle body having an accommodating space, an arm assembly coupled to the vehicle body, and a floating member connected to a bottom surface of the vehicle body. The arm assembly includes a first rotating member, a second rotating member coupled to the first rotating member, and a propeller. The propeller includes a rotatable axle coupled to the second rotating member and extending along a rotating axis. The second rotating member can turn the propeller by rotating the rotatable axle about the rotating axis. The first rotating member can rotate and effect a movement of the second rotating member so as to selectively adjust the rotatable axle to align the rotating axis with a first axial direction and a second axial direction. The arm assembly can rotate relative to the vehicle body to selectively rotate into or out of the accommodating space.
