Operating a personal care device
There is provided a method for operating a personal care device. The method comprises obtaining, using an imaging device, image data relating to a portion of a body of a user; measuring, using the image data, a parameter relating to at least one hair growing from the portion of the body; and determining a position of the portion of the body on the body based on the measured parameter and a predetermined relation between the parameter and the position on the body. A personal care device, a personal care system and a machine-readable medium are also disclosed.
1. A method for identifying a body part of a user while operating a personal care device, the method comprising:
obtaining, using an imaging device, image data relating to at least a portion of the body part to be treated by the personal care device;
measuring, using the image data, a parameter relating to at least one hair growing from the at least a portion of the body part;
identifying, using the personal care device, a location on the body part based on a comparison of the measured parameter and a predetermined relation between the parameter and the body part;
automatically adjusting, via the personal care device, an operating parameter of the personal care device based on the measured parameter relating to the at least one hair, and
performing a personal care activity on the location on the body part using the personal care device based on the automatically adjusted operating parameter of the personal care device.
2. The method according to claim 1 , further comprising:
responsive to identifying the body part, causing the personal care device to perform an action.
3. The method according to claim 2 , wherein the action comprises:
indicating, to the user, the identified body part determined position of the portion of the body on the body.
4. The method according to claim 3 , wherein the indication is visual or audible, wherein a visual indication is made to the user by displaying a textual or pictorial indication of the identified body part on a display screen of the personal care device.
5. A method according to claim 1 , wherein said parameter comprises at least one of: a diameter of a shaft of the at least one hair, an orientation of the at least one hair relative to the body of the user, a pigment of the at least one hair.
6. A method according to claim 1 , comprising measuring the parameter for a plurality of hairs, wherein said parameter comprises at least one of: an area of the portion of the body to which the image data relates which is covered by the plurality of hairs, a sum of cross section areas of shafts of the plurality of hairs growing from the portion of the body, and a degree of uniformity of an orientation of the plurality of hairs relative to the portion of the body.
7. A method according to claim 1 , wherein said predetermined relation is stored in a lookup table or database.
8. A method according to claim 1 , further comprising:
storing at least one of the image data, the measured parameter and the determined position of the portion of the body on the body in a storage device.
9. A method according to claim 1 , further comprising:
transmitting at least one of the image data, the measured parameter and the determined position of the portion of the body on the body to a computing device.
10. The method according to claim 1 , further comprising prompting the user to adjust an operating parameter of the personal care device based on the identified body part.
11. A personal care device comprising:
a personal care element;
an imaging device; and
a processing apparatus configured to:
obtain, using the imaging device, image data relating to at least a portion of a body part of a user to be treated by the personal care device;
measure, using the image data, a parameter relating to at least one hair growing from the at least a portion of the body part;
identify a location on the body part based on a comparison of the measured parameter and a predetermined relation between the parameter and the body part; and
automatically adjust an operating parameter of the personal care device on the location of the body part based on the measured parameter relating to the at least one hair.
12. The personal care device according to claim 11 , wherein the imaging device comprises a device selected from a group comprising: an optical imaging device; a capacitive contact sensor; and an acoustic imaging device.
13. The personal care device according to claim 11 , wherein the processing apparatus is remote or connected to the personal care element and the imaging device.
14. A personal care system comprising:
a personal care device comprising:
a personal care element;
an imaging device configured to obtain image data relating to at least a portion of a body part of a user to be treated by the personal care element;
a controller configured to control the personal care element and the imaging device;
a processing apparatus, remote from the personal care device, configured to:
measure, using the image data, a parameter relating to at least one hair growing from the at least a portion of the body part;
identify a location on the body part based on a comparison of the measured parameter and a predetermined relation between the parameter and the body part; and
automatically adjust an operating parameter of the personal care device on the location on the body part based on the measured parameter relating to the at least one hair.
15. The personal care system according to claim 14 , wherein the controller is configured to:
responsive to identifying the body part, control the personal care device to indicate to the user the identity of the body part.
