Abstract

Eyeglasses including a lens unit including a pair of lenses and a frame, a supporting unit supporting the lens unit, a camera mounted on the frame, a projector mounted on the frame and configured to project content on a screen, and a processor configured to control the camera and the projector. A method of controlling eyeglasses, including generating a first projector image to be projected on a screen by a projector mounted on the eyeglasses, obtaining a camera image from a camera mounted on the eyeglasses, and generating a first user input signal by analyzing the camera image.

Claims

1. Eyeglasses comprising:

a camera mounted between lenses of the eyeglasses;

a first projector mounted on a connection part between one of the lenses of the eyeglasses and a supporting unit;

a second projector mounted on another connection part between another one of the lenses of the eyeglasses and another supporting unit;

a microphone mounted on the eyeglasses; and

a processor configured to control the camera and the first and second projectors,

wherein the processor is further configured to generate two different projector images to be respectively projected by the first and second projectors away from eyes of a user and overlapping onto a screen to form a three-dimensional image on the screen, and to generate an input signal of the user by analyzing a camera image obtained from the camera and a voice command of the user obtained from the microphone,

wherein the processor comprises a voice recognition unit configured to process and analyze the voice command of the user obtained from the microphone, and to convert the voice command into the user input signal, and

wherein the processor is further configured to detect whether or not the user input signal comprises a content operation signal, and to modify the two different projector images to he respectively projected by the first and second projectors based on the detected content operation signal.

2. The eyeglasses of claim 1, wherein the first and second projectors are pico projectors that are mounted in a frame of the eyeglasses.

3. The eyeglasses of claim 1, wherein the screen is a hand of the user.

4. The eyeglasses of claim 1, wherein the processor comprises:

a content generation unit configured to generate the two different projector images to be respectively projected by the first and second projectors; and

an image recognition unit configured to process and analyze the camera image obtained from the camera and to convert the camera image into the input signal of the user.

5. The eyeglasses of claim 4,

wherein the image recognition unit is configured to detect Whether or not the user input signal a comprises the content operation signal, and

wherein the content generation unit is further configured to modify the projector images based on the detected content operation signal.

6. The eyeglasses of claim 5,

wherein the content operation signal is a gesture of the user, and

wherein the processor is configured to detect the content operation signal by using a gesture recognition algorithm.

7. The eyeglasses of claim 1, wherein a number of cameras mounted on the eyeglasses is two.

8. A method of controlling eyeglasses, the method comprising:

generating first and second projector images to be respectively projected away from eyes of a user and overlapping onto a screen by first and second projectors mounted on the eyeglasses to form a three-dimensional image on the screen;

obtaining a camera image from a camera mounted on the eyeglasses;

generating a first input signal of the user by analyzing the camera image;

generating a second input signal of the user by obtaining and analyzing a voice command of the user obtained from a microphone mounted on the eyeglasses; and

detecting whether or not the user'"'"'s second input signal comprises a first content operation signal, and modifying the first and second projector images to be respectively projected by the first and second projectors based on the detected first content operation signal.

9. The method of claim 8, wherein the first and second projectors are pico projectors that are mounted in a frame of the eyeglasses.

10. The method of claim 8, wherein the screen is a hand of the user.

11. The method of claim 8, further comprising generating a third projector image by modifying the first projector image when the user'"'"'s first input signal comprises a second content operation signal with respect to the first projector image.

12. The method of claim 11,

wherein the second content operation signal is a gesture of the user, and

wherein the generating of the user'"'"'s first input signal comprises detecting the second content operation signal by using a gesture recognition algorithm.

13. The method of claim 8, wherein a number of cameras mounted on the eyeglasses is two.

14. The method of claim 13,

wherein the obtaining of the camera image comprises obtaining two camera images for forming a three-dimensional camera image.
