Abstract

Embodiments are disclosed that relate to authenticating a user of a display device. For example, one disclosed embodiment includes displaying one or more virtual images on the display device, wherein the one or more virtual images include a set of augmented reality features. The method further includes identifying one or more movements of the user via data received from a sensor of the display device, and comparing the identified movements of the user to a predefined set of authentication information for the user that links user authentication to a predefined order of the augmented reality features. If the identified movements indicate that the user selected the augmented reality features in the predefined order, then the user is authenticated, and if the identified movements indicate that the user did not select the augmented reality features in the predefined order, then the user is not authenticated.

Claims

1. A method for authenticating a user of a computing system comprising a display device, comprising:

displaying one or more virtual images on the display device, the one or more virtual images comprising a set of augmented reality features;

identifying one or more movements of the user via data received from a sensor of the computing system;

comparing the identified movements of the user to a predefined set of authentication information for the user that links user authentication to a predefined order of the augmented reality features;

if the identified movements indicate that the user selected the augmented reality features in the predefined order, then authenticating the user; and

if the identified movements indicate that the user did not select the augmented reality features in the predefined order, then not authenticating the user.

2. The method of claim 1, wherein the sensor comprises an inertial motion sensor, and wherein the data comprises inertial motion data.

3. The method of claim 1, wherein the sensor comprises an eye tracking sensor system, and wherein the data comprises eye movement data.

4. The method of claim 1, wherein the predefined order of the augmented reality features is user-selected.

5. The method of claim 1, wherein the one or more virtual images are displayed in a similar location each time the user is authenticated.

6. The method of claim 1, wherein the one or more virtual images are displayed in a different location in different authentication sessions.

7. The method of claim 1, further comprising outputting an indication that the user has selected an augmented reality feature if an identified movement of the user matches a movement associated with the augmented reality feature.

8. The method of claim 1, further comprising determining a confidence score reflecting a level of confidence that the user selected augmented reality features in the predefined order.

9. The method of claim 8, further comprising, if the confidence score is greater than a threshold, then authenticating the user, and if the confidence score is less than the threshold, then not authenticating the user.

10. The method of claim 9, wherein the threshold is based on a location of the user.

11. The method of claim 8, wherein the threshold varies based on a number of augmented reality features.

12. The method of claim 8, wherein the set of augmented reality features includes virtual features and real objects in a field of view of the user.

20. The method of claim 10, wherein the threshold is based on a determined ability of the sensor to identify the one or more movements of the user.

13. A method for authenticating a user of a head-mounted display device, the method comprising:

receiving a set of authentication inputs to authenticate a user, the set of authentication inputs comprising one or more authentication inputs selected from a plurality of recognized authentication inputs for the user, the plurality of recognized authentication inputs comprising recognized authentication inputs of a plurality of different input modes corresponding to different input sensors of the head-mounted display device;

if the set of authentication inputs comprises a first set of authentication inputs of different modes, then authenticating the user with a first, lower confidence score; and

if the set of authentication inputs comprises a second set of authentication inputs of different modes, then authenticating the user with a second, higher confidence score.

14. The method of claim 13, wherein the plurality of recognized authentication inputs comprises one or more of a gaze tracking input, a head movement, a body movement, an audio command, a user orientation, a time of day, a user location, a biometric signature, and a presence of other users.

15. The method of claim 13, wherein the set of authentication inputs includes the first set of authentication inputs if the user is located in a first location and includes the second set of authentication inputs if the user is located in a second location that is different than the first location.

16. The method of claim 13, wherein authenticating the user with the first, lower confidence score further comprises comparing the first confidence score to a first threshold and if the first confidence score exceeds the first threshold, then authenticating the user.

17. A method for authenticating a user of a head-mounted display device, the method comprising:

displaying one or more virtual images on the head-mounted display device, the one or more virtual images comprising a set of augmented reality augmented reality features;

identifying one or more movements of the user via a sensor of the head-mounted display device;

comparing the identified movements of the user to a predefined set of authentication information for the user that links user authentication to a predefined order of the augmented reality features;

assigning a confidence score to the identified movements, the confidence score reflecting a level of confidence that the user selected the augmented reality features in the predefined order;

if the confidence score is greater than a threshold, then authenticating the user; and

if the confidence score is not greater than the threshold, then not authenticating the user.

18. The method of claim 17, wherein the sensor comprises one or more of an inertial motion sensor and an eye tracking sensor.

19. The method of claim 17, wherein the threshold is based on a location of the user, and further comprising applying different thresholds at different locations.
