Abstract

Systems and methods for remotely providing user input to different electronic devices based on user finger motions and/or gestures. A universal user input device assembles a motion sensor, control logic, a memory and a processor into a substantially ring-shaped housing that is wearable on a finger of a user. The input device can identify an associated external device, establish a communication channel therewith, and provide user input instructions to the external device based on user's finger motions or gestures. The motion sensor can detect the finger's motions and/or gestures and generate corresponding detection signals which are converted into instruction signals recognizable by the external device. The instruction signals are communicated to the external device through a wireless communication channel. The input device may include a projector that can optically project a graphic user interface to an external surface as a visual guide for user's finger motions or gestures.
