Patent attributes
An electronic device with a camera invokes a wireless communications pairing mode for pairing the electronic device with an external device. The electronic device obtains an image via the camera. The image contains a pattern displayed on a display screen of the external device, and the pattern comprises identifying information of the external device. The electronic device receives data from the external device, determines whether the received data corresponds with the identifying information, and, in response to a determination that the received data corresponds with the identifying information, registers the external device as a paired device. In some examples, the electronic device is a smartphone and the external device is a wearable electronic device. Pairing the electronic device and the external device may allow the devices to exchange information and operate interactively with one another.
