Abstract

In a method of simulating a lens using augmented reality, a user who desires to purchase a vision correction product may wear lenses precisely corrected using a computer device through a virtual experience, and inconvenience of frequently replacing various lenses when taking an eye examination is considerably mitigated. An effect of wearing a variety of vision correction products in a short time period can be experienced, and it is expected to be able to select an optimized custom-tailored vision correction product. Particularly, in manufacturing a functional lens which has complicated manufacturing steps and requires a precise examination, such as a progressive multi-focal lens, a coating lens, a color lens, a myopia progress suppression lens, an eye fatigue relieve lens or the like, it is expected that a precise product can be manufactured, and manufacturing time can be greatly reduced.

Claims

1. A method of simulating a lens using augmented reality, which uses a portable tablet computer applied with a screen module having an input and out function, a camera module for photographing a surrounding environment in real-time, a motion sensor module for sensing a motion pattern according to handling of a user, and an operation module for storing and/or processing information received from the screen module, the camera module and the motion sensor module, the method comprising the steps of:

acquiring information on an image of a real surrounding environment by photographing the real surrounding environment using the camera module;

acquiring information on a motion of visually recognizing an object of the user by sensing a motion pattern according to handling of the user through the motion sensor module;

creating a virtual custom-tailored spectacle lens image based on the information on the motion of visually recognizing an object of the user through the operation module; and

disposing the virtual custom-tailored spectacle lens image to be overlapped with the real surrounding environment image and outputting a vision adjustment effect image based on the virtual custom-tailored spectacle lens image.

2. The method according to claim 1, wherein said acquiring information on a motion of visually recognizing an object of the user comprises:

acquiring information on a distance between eyes of the user and the portable tablet computer by sensing a motion pattern of the user approaching the eyes of the user toward a direction of the portable tablet computer or pulling the portable tablet computer toward a direction of the eyes of the user in order to confirm an image outputted on the screen module; and

acquiring information on a position of a face of the user by sensing a motion pattern of the user moving the face of the user up and down or left and right in order to confirm an image outputted on the screen module.

3. The method according to claim 1, wherein the virtual custom-tailored spectacle lens image is implemented in a form of two-dimension 2D or three-dimension 3D.

4. The method according to claim 1, wherein the virtual custom-tailored spectacle lens image is selected from a group of a progressive lens image, a progressive multi-focal lens image, a spherical lens image, an aspherical lens image, a double-sided aspherical lens image, a myopia progress suppression lens image, an eye fatigue relieve lens image, a color lens image, and a coating lens image.

5. The method according to claim 1, wherein said outputting a vision adjustment effect image based on the virtual custom-tailored spectacle lens image comprises additionally outputting a virtual background image or a function handling button image stored in the portable tablet computer.

6. The method according to claim 1, wherein the portable tablet computer is additionally applied with an optical sensor module.

7. The method according to claim 6, wherein the optical sensor module is implemented in an embedded type embedded in the portable tablet computer or implemented in an external type connected to an audio connection port of the portable tablet computer.

8. The method according to claim 6, further comprising:

acquiring information on external light by sensing the external light through the optical sensor module; and

creating the virtual custom-tailored spectacle lens image based on the information on external light through the operation module.

9. The method according to claim 5, wherein the virtual custom-tailored spectacle lens image is a discoloration lens image or a polarization lens image.

10. The method according to claim 1, wherein the lens is a spectacle lens.

11. A method of simulating a lens using augmented reality, comprising:

acquiring first information on an image photographed by a camera module;

acquiring second information on a motion of visually recognizing an object of a user by sensing a motion pattern according to handling of the user, with a motion sensor module;

creating a virtual custom-tailored spectacle lens image based on the second information by an operation module; and

disposing the virtual custom-tailored spectacle lens image to be overlapped with the image photographed by the camera module to make a vision adjustment effect image and outputting the vision adjustment effect image on a screen module.

12. The method according to claim 11, wherein at least one of the camera module, the motion sensor module, the operation module and the screen module are drivably connected to a tablet.

13. The method according to claim 11, wherein the camera module, the motion sensor module, the operation module and the screen module are embedded in a tablet.

14. The method according to claim 11, wherein said acquiring the second information comprises:

outputting an image on the screen module; and

acquiring the second information on a distance between eyes of the user and the screen module by sensing a motion pattern of the user when the user moves himself or herself or moves the screen module in order to confirm the image outputted on the screen module.

15. The method according to claim 11, wherein said acquiring the second information comprises:

outputting an image on the screen module; and

acquiring the second information on a position of a face of the user by sensing a motion pattern of the user when the user moves the face of the user in order to confirm an image outputted on the screen module.

16. The method according to claim 11, wherein the second information comprises information on an eye rotation and a length of corridor motion pattern.

17. The method according to claim 11, wherein said acquiring the second information further comprises:

acquiring external light information by sensing external light with an optical sensor module; and

creating the virtual custom-tailored spectacle lens image based on the second information containing the external light information with the operation module.

18. The method according to claim 11, wherein the lens is a spectacle lens.

19. The method according to claim 11, wherein the lens is a contact lens.

20. The method according to claim 11, wherein the virtual custom-tailored spectacle lens image comprises a plurality of virtual custom-tailored spectacle lens images selected from a group of a progressive lens image, a progressive multi-focal lens image, a spherical lens image, an aspherical lens image, a double-sided aspherical lens image, a myopia progress suppression lens image, an eye fatigue relieve lens image, a color lens image, and a coating lens image.
