Abstract

Claims (41)

1. A method comprising:

obtaining bending data indicative of bending of an extended reality (XR) device to accommodate a body part of a user wearing the XR device;

determining, based on the bending data, whether to use previously identified biometric data in a tracking operation;

responsive to determining whether to use the previously identified biometric data, selecting a mode of the XR device, the selected mode being a first mode or a second mode, the first mode being based on determining to use the previously identified biometric data in the tracking operation and the second mode being based on determining not to use the previously identified biometric data in the tracking operation; and

using the selected mode to initialize the tracking operation.

2. The method of claim 1 , wherein the tracking operation comprises tracking a feature of the user wearing the XR device.

3. The method of claim 2 , wherein the feature is a hand of the user wearing the XR device, and the previously identified biometric data comprises a previously obtained hand feature calibration.

4. The method of claim 1 , wherein the previously identified biometric data comprises a hand feature estimate generated during a previous user session.

5. The method of claim 1 , wherein the bending data comprises at least one of: a measurement of the bending of the XR device generated by at least one sensor of the XR device; or an estimate of the bending of the XR device.

6. The method of claim 1 , wherein the bending data is first bending data, and wherein the determining whether to use the previously identified biometric data in the tracking operation comprises:

comparing the first bending data to second bending data associated with the previously identified biometric data.

7. The method of claim 6 , wherein the second bending data comprises a measurement or estimate of the bending of the XR device generated during a previous user session.

8. The method of claim 6 , wherein the selected mode is the first mode in which the previously identified biometric data is selected for use in the initializing of the tracking operation, and the first mode is selected based on determining that the first bending data matches the second bending data.

9. The method of claim 8 , further comprising:

identifying, based on the determining that the first bending data matches the second bending data, that no calibration operation is required for the user.

10. The method of claim 9 , further comprising:

adjusting the previously identified biometric data during the tracking operation.

11. The method of claim 10 , wherein the previously identified biometric data is adjusted so as to refine the biometric data across multiple user sessions.

12. The method of claim 8 , wherein the determining that the first bending data matches the second bending data comprises determining that the first bending data is within an acceptable bending range of the second bending data.

13. The method of claim 8 , further comprising:

detecting, based on the determining that the first bending data matches the second bending data, that the user corresponds to a previous user of the XR device, the previous user being associated with the second bending data and the previously identified biometric data.

14. The method of claim 6 , wherein the selected mode is the second mode in which a calibration operation is performed for the user, and the second mode is selected based on determining that the first bending data does not match the second bending data.

15. The method of claim 14 , further comprising:

performing the calibration operation to obtain new biometric data for use in the tracking operation; and

associating the new biometric data with the first bending data.

16. The method of claim 14 , further comprising:

detecting, based on the determining that the first bending data does not match the second bending data, that the user does not correspond to a previous user of the XR device, the previous user being associated with the second bending data and the previously identified biometric data.

17. A system comprising:

at least one processor; and

at least one memory component storing instructions that, when executed by the at least one processor, configure the system to perform operations comprising:

obtaining bending data indicative of bending of an extended reality (XR) device to accommodate a body part of a user wearing the XR device;

determining, based on the bending data, whether to use previously identified biometric data in a tracking operation;

responsive to determining whether to use the previously identified biometric data, selecting a mode of the XR device, the selected mode being a first mode or a second mode, the first mode being based on determining to use the previously identified biometric data in the tracking operation and the second mode being based on determining not to use the previously identified biometric data in the tracking operation; and

using the selected mode to initialize the tracking operation.

18. The system of claim 17 , wherein the tracking operation comprises tracking a feature of the user wearing the XR device.

19. The system of claim 18 , wherein the feature is a hand of the user wearing the XR device, and the previously identified biometric data comprises a previously obtained hand feature calibration.

20. A non-transitory computer-readable storage medium, the computer-readable storage medium including instructions that when executed by at least one processor, cause the at least one processor to perform operations comprising:

obtaining bending data indicative of bending of an extended reality (XR) device to accommodate a body part of a user wearing the XR device;

determining, based on the bending data, whether to use previously identified biometric data in a tracking operation;

responsive to determining whether to use the previously identified biometric data, selecting a mode of the XR device, the selected mode being a first mode or a second mode, the first mode being based on determining to use the previously identified biometric data in the tracking operation and the second mode being based on determining not to use the previously identified biometric data in the tracking operation; and

using the selected mode to initialize the tracking operation.
