Unlocking passwords in augmented reality based on look

1. A method of using a head-mounted display (HMD) to enable the display of confidential data, the method comprising:

authenticating a user by:

placing the HMD on the head of the user;

moving the HMD by moving the head of the user to facilitate the user looking at a series of N objects, each object defined at a distinct point in a physical space in a predefined order;

mapping each object of the N objects to a spatial position in the physical space;

providing at least one virtual object in a password space, the password space defined by a square cross-section annular ring surrounding the user; and

providing access to the confidential data in response to the user looking at a spatial position in the physical space corresponding to each object of the predefined series of N objects in the predefined order and within a predefined time frame, wherein N is greater than zero, and wherein at least one of the N objects is a physical object, wherein the user may be positioned anywhere within the physical space when looking at the spatial position of each object.

2. The method of claim 1 , wherein N is greater than or equal to three.

3. The method of claim 1 , further comprising moving the HMD by moving the head of the user to look at an object in the physical space and displaying confidential data about that object in the HMD.

4. The method of claim 1 , wherein each of the N objects is a physical object positioned within a single physical space.

5. The method of claim 4 , wherein the N objects are selected such that each of the N objects is visible from any point within the physical space.

6. The method of claim 5 , wherein the user can be positioned at any point in the physical space during the authentication steps.

7. The method of claim 1 , wherein the predefined time frame is between 10 seconds and 60 seconds.

8. The method of claim 1 , further comprising displaying a password space including a plurality of pre-selected virtual objects.

9. The method of claim 8 , wherein at least one of the N objects is a virtual object selected from the pre-selected virtual objects and at least one of the N objects is a physical object that is positioned within a fixed physical space.

10. A method of using a head-mounted display (HMD) to enable the display of confidential data, the method comprising:

authenticating a user by:

initiating a login process;

starting a timer;

moving the HMD with the head of the user to facilitate the user looking at a first distinct point in a physical space containing a first object;

moving the HMD with the head of the user to facilitate the user looking at a second distinct point in the physical space containing a second object;

moving the HMD with the head of the user to facilitate the user looking at an Nth object;

mapping each object of the N objects to a spatial position in the physical space;

defining at least one of the N objects as a virtual object in a password space, the password space defined by a square cross-section annular ring surrounding the user; and

providing access to the confidential data in response to looking at a spatial position in the physical space corresponding to the first object through the Nth object in a predefined order prior to the passage of a predetermined amount of time as measured by the timer, wherein at least one of the N objects is a physical object positioned within the physical space and wherein the user may be positioned anywhere within the physical space when looking at the spatial position of each object.

11. The method of claim 10 , further comprising moving the HMD by moving the head of the user to look at an object in the physical space and displaying confidential data about that object in the HMD.

12. The method of claim 10 , wherein each of the N objects is a physical object positioned within the physical space.

13. The method of claim 10 , wherein at least one of the N objects is a virtual object selected from the pre-selected virtual objects and at least one of the N objects is the physical object that is positioned within the physical space.

14. The method of claim 10 , further comprising immediately re-initiating the login process when the predetermined amount of time passes.

15. A method of using a head-mounted display (HMD) to enable the display of confidential data, the method comprising:

authenticating a user by:

initiating a login process;

moving the HMD with the head of the user to facilitate the user looking at a first distinct point in a physical space containing a first object (Xth object) within a predefined time from the initiation of the login process; and

moving the HMD with the head of the user to facilitate the user looking at a second distinct point in a physical space containing a an Xth plus one object within a predefined time from the completion of looking at the distinct point in the physical space containing the Xth object;

mapping each object of the N objects to a spatial position in the physical space;

defining at least one of the N objects as a virtual object in a password space, the password space defined by a square cross-section annular ring surrounding the user; and

providing access to the confidential data in response to looking at the spatial position in the physical space containing the first object through an Nth object in a predefined order without exceeding any of the predefined times, wherein at least one of the N objects is a physical object positioned within the physical space, and wherein the user may be positioned anywhere within the physical space when looking at the spatial position of each object.

16. The method of claim 15 , wherein failing to complete any of the moving steps within the prescribed time limit re-initiates the login process.

17. The method of claim 15 , further comprising displaying a password space including a plurality of pre-selected virtual objects.

18. The method of claim 17 , wherein at least one of the N objects is a virtual object selected from the pre-selected virtual objects and at least one of the N objects is the physical object that is positioned within the physical space.

19. The method of claim 15 , wherein N is greater than or equal to three.
