Abstract

A head mounted display device is capable of providing user a type of augmented reality (AR) experience with private access of the augmentation elements as represented by computer-generated (CG) contents. The core of the device comprises an optical combiner and a layer of photochromic materials or other means alike that changes from transparent to opaque when subjected to appropriate conditions, such that an occlusion mask pattern occupying a small portion of the said layer is created with dimension and position correspond to the CG content. The device allows user to selectively conceal the CG content from the surrounding people while keeping a sight of the real world whose elements are augmented or supplemented.

Claims

1. An optical see-through head mount display (HMD) device for displaying a computer-generated (CG) content to a user to provide a type of augmented reality (AR) with private access of information, wherein the HMD comprises of:

an optical see-through display system for each of an user'"'"'s eyes comprising;

an optical combiner; and

an optical means that changes from transparent to opaque for creating an occlusion mask pattern;

a computer-generated (CG) content engine;

an on-board computing system coupled to the computer-generated (CG) content engine to generate spatially-registered CG content; and

an image source for each of the user'"'"'s eyes to display the spatially-registered CG content through the optical combiner.

2. The optical see-through HMD device as in claim 1, wherein the on-board computing system further comprises:

a processor to control the optical means in creating the occlusion mask pattern on the optical means, in which dimension and position of the occlusion mask pattern corresponds to dimension and position of the spatially-registered CG content being displayed on the optical combiner.

3. The optical see-through HMD device as in claim 1, wherein the on-board computing system further comprises:

a processor to control the optical means in creating an occlusion mask pattern on the optical means, wherein color of the occlusion mask is dynamically selected by the on-board computing system.

4. The optical see-through HMD device as in claim 3, wherein the on-board computing system further comprises:

a processor to control color of the spatially-registered CG content based on the color of the occlusion mask.

5. The optical see-through HMD device as in claim 1, wherein the on-board computing system further comprises:

a processor to identify the type of CG content being displayed on the optical combiner such that an occlusion mask pattern is created on the optical means that blocks off the spatially-registered CG content completely or partially from view of surrounding people.

6. The optical see-through HMD device as in claim 1, wherein the on-board computing system further comprises:

a processor to identify the type of CG content being displayed on the optical combiner such that an occlusion mask pattern is not created and the optical means remain transparent.

7. The on-board computing system as in claim 1, wherein the occlusion mask pattern created on the optical means can be switched on and off based on user preference.

8. The optical see-through HMD device as in claim 1, wherein the optical combiner has diffraction gratings.

9. The optical see-through HMD device as in claim 1, wherein the occlusion mask pattern acts a background for enhancing readability of the spatially-registered CG content.

10. The optical see-through HMD device as in claim 1, wherein color of the occlusion mask pattern can be fixed or dynamic.

11. The optical see-through HMD device as in claim 1, wherein the on-board computing system further comprises:

a processor to create an occlusion mask pattern on the optical means based on a user preference; and

an image processor to render a composited scene by electronically combining an image of an augmented object in the real world and the spatially-registered CG content.

12. A method of displaying a computer-generated (CG) content to a user wearing a head mounted display (HMD) to provide a type of augmented reality (AR) with private access of information, the method comprising:

generating a spatially-registered CG content by a computing system;

creating an occlusion mask pattern by changing optical property of an optical means present on the head mounted display (HMD);

displaying the spatially-registered CG content to the user such that the occlusion mask pattern acts as a background for the spatially registered CG content.

13. The method of displaying a computer-generated (CG) content to a user wearing a head mounted display (HMD) as in claim 12, wherein color of the occlusion mask pattern can be fixed or dynamic.

14. The method of displaying a computer-generated (CG) content to a user wearing a head mounted display (HMD) as in claim 13, wherein color of the spatially registered (CG) content is based on the color of the occlusion mask pattern.

15. The method of displaying a computer-generated (CG) content to a user wearing a head mounted display (HMD) as in claim 12, wherein the head mounted display (HMD) further comprises an optical combiner.

16. The method of displaying a computer-generated (CG) content to a user wearing a head mounted display (HMD) as in claim 15, wherein the optical combiner has diffraction gratings.
