Abstract

A method of routing the display of secure content to a head mounted display device via a host information handling system may comprise receiving, via a processor, a request to initiate a new user session from a user, measuring, via a brain wave detection controller, a brain wave pattern signal across a plurality of brain wave detection sensors mounted with a head mounted display device, if the brain wave pattern signal is identified as a brain wave pattern, prompting the user for valid user credentials, receiving, via the processor, user credentials from the user, and if the user credentials match credential records stored in a memory associated with an authenticated user, granting the user access to the head mounted display device.

First claim

What is claimed is:

1. An information handling system operating an head-mounted display secure session maintenance system comprising:
a head mounted display device mounted within a wearable headset;
a plurality of brain wave detection sensor mounted within the wearable headset such that the plurality of brain wave detection sensors make contact with a wearer's scalp upon placement of the wearable headset on the wearer's head;
a processor receiving a user input positively identifying the user as an authenticated user;
a brain wave detection controller measuring a first difference in voltage across the plurality of brain wave detection sensors;
the brain wave detection controller measuring a first brain wave pattern signal across the plurality of brain wave detection sensors if the first difference in voltage across the plurality of brain wave detection sensors meets or exceeds five microvolts; and
a head mounted display of the head mounted display device displaying three-dimensional images of data content if the measured first brain wave pattern signal is identified as a brain wave pattern.

2. The information handling system of claim 1 further comprising:
the brain wave detection controller measuring a second difference in voltage across the plurality of brain wave detection sensors after a preset time period elapses; and
the head mounted display of the head mounted display device ceasing display of three-dimensional images of data content if the measurement of the second difference in voltage across the plurality of brain wave detection sensors does not meet or exceed five microvolts.

3. The information handling system of claim 1 , wherein the identified brain wave pattern is a beta brain wave pattern that is a sinusoidal signal having a frequency between 13 and 30 Hz.

4. The information handling system of claim 1 , wherein the identified brain wave pattern is a beta brain wave pattern that is a sinusoidal signal having an amplitude between five and ten microvolts.

5. The information handling system of claim 1 further comprising:
the head mounted display displaying a message that the user has been denied access to the head mounted display if the measurement of the first difference in voltage across the plurality of brain wave detection sensors does not meet the preset voltage difference threshold.

6. The information handling system of claim 1 , wherein the user input positively identifying the user as an authenticated user is an iris scan.

7. The information handling system of claim 1 , wherein the user input positively identifying the user as an authenticated user is a fingerprint scan.

8. A method of routing the display of secure content to a head mounted display device via a host information handling system comprising:
measuring, via a brain wave detection controller, a first difference in voltage across a plurality of brain wave detection sensors mounted with a head mounted display device;
measuring, via the brain wave detection controller, a first brain wave pattern signal across the plurality of brain wave detection sensors if the first difference in voltage across the plurality of brain wave detection sensors meets or exceeds five microvolts;
if the first brain wave pattern signal is identified as a beta brain wave pattern, prompting the user for valid user credentials via a processor;
receiving, via the processor, user credentials from the user; and
if the user credentials match credential records stored in a memory associated with an authenticated user, granting the user access to the head mounted display device.

9. The method of claim 8 further comprising:
continuously measuring a second brain wave pattern signal across the plurality of brain wave detection sensors via the brain wave detection controller after granting the user access to the head mounted display device; and
ceasing display of three-dimensional images of data content via a head mounted display of the head mounted display device if the second brain wave pattern signal is not the beta brain wave pattern.

10. The method of claim 9 , wherein the beta brain wave pattern is a sinusoidal signal having a frequency between 13 and 30 Hz.

11. The method of claim 9 , wherein the beta brain wave pattern is a sinusoidal signal having an amplitude between five and ten microvolts.

12. The method of claim 8 further comprising:
denying the user access to the head mounted display device if the user credentials do not match credential records stored in a memory associated with an authenticated user.

13. The method of claim 8 , wherein the user credentials include a correct password.

14. The method of claim 8 , wherein the user credentials include a retinal scan.

15. An information handling system operating an head-mounted display secure session maintenance system comprising:
a head mounted display device mounted within a wearable headset;
a plurality of brain wave detection sensor mounted within the wearable headset such that the plurality of brain wave detection sensors make contact with a wearer's scalp upon placement of the wearable headset on the wearer's head;
a processor receiving a user input positively identifying the user as an authenticated user;
a brain wave detection controller measuring a first difference in voltage across the plurality of brain wave detection sensors;
the brain wave detection controller measuring a first brain wave pattern signal across the plurality of brain wave detection sensors if the first difference in voltage across the plurality of brain wave detection sensors meets or exceeds five microvolts;
a head mounted display of the head mounted display device displaying three-dimensional images of data content if the first brain wave pattern signal is identified as a brain wave pattern; and
the head mounted display denying the user access to the head mounted display if the first brain wave pattern is not identified as the brain wave pattern.

16. The information handling system of claim 1 further comprising:
the brain wave detection controller continuously measuring a second brain wave pattern signal across the plurality of brain wave detection sensors via the brain wave detection controller after granting the user access to the head mounted display device; and
the head mounted display of the head mounted display device ceasing display of three-dimensional images of data content via a head mounted display of the head mounted display device if the second brain wave pattern signal is not the brain wave pattern.

17. The information handling system of claim 15 , wherein the brain wave pattern is a beta brain wave pattern that is a sinusoidal signal having a frequency between 13 and 30 Hz.

18. The information handling system of claim 15 , wherein the brain wave pattern is a beta brain wave pattern that is a sinusoidal signal having an amplitude between five and ten microvolts.

19. The information handling system of claim 15 , wherein the user input positively identifying the user as an authenticated user is an iris scan.

20. The information handling system of claim 15 , wherein the user input positively identifying the user as an authenticated user is a fingerprint scan.
