Abstract: An external device, such as a head-mountable device, can be operated with a ring input device worn on a finger of a user. Such devices can be operated to provide inputs that are received and acted upon by the external device. The inputs can be provided as rotating, tilting, and/or sliding at least a portion of the ring input device with another finger of the user. The ring input device can provide feedback to the user as confirmation that the inputs are being received. A feedback system can also be operated to limit or otherwise provide a force on the finger and/or another portion of the hand to simulate sensations perceived by the user.
