Abstract: In this application, a same input device may randomly switch a focus device between a plurality of terminal devices. Before and after the focus device is switched, the input device may simultaneously maintain communication connections to the plurality of terminal devices, and exchange, in a background, information with a non-focus device based on a communication connection between the input device and the non-focus device. Based on the solutions disclosed in this application, the input device can implement seamless focus migration between the plurality of terminal devices based on a convenient operation of a user without relying on a wireless local area network (WLAN).
