Abstract

A method of designing an earpiece for a user, includes: obtaining 3D scan data of an ear; obtaining a model earpiece with an earpiece configuration based on the 3D scan data; determining coupling data indicative of a coupling of the model earpiece, the coupling data including misfit data including one or more misfit parameters; evaluating the earpiece configuration based on the misfit data; and determining information regarding a personalized earpiece based on a result from the act of evaluating the earpiece configuration.

Claims (29)

1. A method of designing an earpiece for a user, the method comprising:

electronically obtaining 3D scan data of an ear;

electronically generating a model earpiece with an earpiece configuration based on the 3D scan data;

after the model earpiece is generated, electronically evaluating the model earpiece by a processing unit to determine whether the model earpiece is too protruding, too tight, or too loose for the user before an initial physical earpiece is provided to the user, wherein the processing unit is configured to perform a comparison between a misfit parameter for the model earpiece and reference misfit parameter for reference earpieces;

electronically determining, by the processing unit, information regarding a personalized earpiece based on the model earpiece and the misfit parameter; and

providing the information regarding the personalized earpiece for processing by a manufacturing entity, wherein the manufacturing entity is configured to produce the earpiece having a physical feature corresponding with the information regarding the personalized earpiece.

2. The method according to claim 1 , further comprising labelling the model earpiece with a misfit label indicative of misfit if a misfit criterion is satisfied.

3. The method according to claim 1 , wherein the misfit parameter

indicates whether the model earpiece is too protruding, is too tight, or is too loose.

4. The method according to claim 1 , further comprising:

updating the model earpiece to a secondary model earpiece; and

evaluating the secondary model earpiece to determine one or more secondary misfit parameters.

5. The method according to claim 4 , wherein the information regarding the personalized earpiece is based on a result from the act of evaluating the secondary model earpiece.

6. The method according to claim 1 , further comprising providing an evaluation output including a fit label indicative of fit.

7. The method according to claim 1 , further comprising providing an evaluation output including a misfit label indicative of misfit.

8. The method according to claim 1 , wherein the method is performed prior to providing the initial physical earpiece or any other physical earpiece corresponding to the 3D scan data to the user.

9. The method according to claim 1 , wherein the 3D scan data is based on a 3D scan of an impression of the ear.

10. The method according to claim 1 , wherein the 3D scan data is based on a 3D scan of the ear.

11. The method according to claim 1 , wherein the 3D scan data comprises front pinna data, back pinna data, and ear canal data.

12. The method according to claim 1 , wherein the misfit parameter indicates one or more probabilities of misfit and/or fit of the model earpiece.

13. The method according to claim 1 , wherein the misfit parameter comprises a probability value.

14. An electronic device for designing an earpiece, the electronic device comprising one or more processors, memory, and an interface, wherein the one or more processors are configured to:

electronically obtain 3D scan data of an ear of a user;

electronically generate a model earpiece with an earpiece configuration based on the 3D scan data;

after the model earpiece is generated, electronically evaluate the model earpiece to determine whether the model earpiece is too protruding, too tight, or too loose for the user before an initial physical earpiece is provided to the user, wherein the one or more processors are configured to perform a comparison between a misfit parameter for the model earpiece and reference misfit parameter for reference earpieces;

electronically determine information regarding a personalized earpiece the model earpiece and the misfit parameter; and

providing the information regarding the personalized earpiece for processing by a manufacturing entity, wherein the manufacturing entity is configured to produce the earpiece having a physical feature corresponding with the information regarding the personalized earpiece.

15. The electronic device according to claim 14 , wherein the misfit parameter indicates one or more probabilities of misfit and/or fit of the model earpiece.

16. The electronic device according to claim 14 , wherein the misfit parameter comprises a probability value.
