Abstract
An electronic device is provided. The electronic device includes a communication circuit, an antenna, a wireless charging coil, a positioning sensor circuit, and a processor. The communication circuit may connect communication with a remote input device and a wearable device. The antenna may transmit/receive a signal with respect to the remote input device and the wearable device. The wireless charging coil may detect an attachment and detachment of the remote input device and transmit/receive an electromagnetic signal with respect to the remote input device. The positioning sensor circuit may measure a distance to the remote input device. The processor may determine an attachment and detachment of the remote input device, based on the electromagnetic signal, and recognizing the distance to the remote input device. The processor may provide the wearable device with a remote notification signal based on the distance to the remote input device.
