Abstract: Disclosed are devices for wearing on fingers, and similar devices held by fingers, and systems which include said devices, some of which include various sensing means for facilitating different types of interactions, or for registering input which may be utilized by interfaces, such as for performing certain functions and providing certain features. Further provided are methods of interaction which utilize said devices, and related interfaces.

Abstract: Disclosed herein are finger-worn devices in various embodiments, and related systems, interfaces and methods of use. In some embodiments, a finger-worn device may be connected and disconnected from other devices. In some embodiments, a finger-worn device may relay tactile information to a finger wearing said finger-worn device, and/or to a finger operating said finger-worn device. In some embodiments, a finger-worn device may be operated to generate sound, whereas in some embodiments, a finger-worn device may be operated to generate visual output. In some embodiments, interfaces are intended to react, or be controlled or influenced by a finger-worn device or plurality thereof. In some methods, a finger-worn device may be operated for registering input in systems which can sense and process sounds, whereas in other methods a finger-worn device may be operated for registering input in systems which can sense and process light.
