Abstract
A method alerts a user of a first device to the presence of a second device which can interact with the first device. The method includes using an ultrasonic signal transmitted by one of the devices to determine whether the first device is within a threshold distance of the second device. If the first device is determined to be within the threshold distance of the second device, a notification is triggered on the first device.
