A wearable electronic device includes a body defining an aperture therethrough, sized and shaped to receive a digit of a user. The wearable electronic device may include a processor housed in the body and an input device at least partially extending from an outer surface of the body to receive input from another digit of the user. The input device has an actuating surface that is movable between a first position and a second position. Movement of the actuating surface between the first position and second position provides an input to the processor. The wearable electronic device includes a transmitter coupled to the processor and configured to send electronic transmissions to an external electronic device, the electronic transmissions corresponding to the inputs received from the user, and a power source for providing power to the processor, the input device, and the transmitter.
