Abstract

A gesture recognition based input device includes a number of finger wear components and image capture modules, and an image capture module. Each finger wear component dedicatedly reflects light of a unique wavelength. Each image capture module dedicatedly picks up light reflected by a corresponding finger wear component and thereby dedicatedly captures images of the corresponding finger wear component. The image recognition module recognizes movements of the finger wear components from the images and interprets the movements of the finger wear components into control signals.

Claims

1. An input device comprising:

a first light emitter for emitting a first light of a first wavelength;

a second light emitter for emitting a second light of a second wavelength;

a first finger component for being worn on a finger, configured to dedicatedly reflect the first light;

a second finger component for being worn on a finger, configured to dedicatedly reflect the second light;

a first image capture module sensible to the first light reflected by the first finger component but insensible to the second light, and configured to capture images of the first finger component;

a second image capture module sensible to the second light reflected by the second finger component but insensible to the first light, and configured to capture images of the second finger component; and

an image recognition module configured to determine movement traces of the first and second finger components based on the images of the first and second finger components;

wherein the first and second finger components are separated from and move independently in relation to the first and second light emitters.

2. The input device of claim 1, wherein the first finger component comprises an outermost reflective film to reflect the first light, and the second finger component comprises an outermost reflective film to reflect the second light.

3. The input device of claim 1, wherein the finger components are selected from a group consisting of cots and rings.

4. The input device of claim 1, wherein the first image capture device comprises a filter for allowing the first light to pass therethrough, and the second image capture device comprises a filter for allowing the second light to pass therethrough.

5. The input device of claim 1, wherein the image capture devices are camera modules.

6. The input device of claim 1, wherein the light emitters are light-emitting diodes.

7. The input device of claim 1, wherein the first and second lights are infrared lights.

8. The input device of claim 2, wherein the first and second finger components are cots, and the reflective films are formed on an outer surface of the respective cots.
