Abstract

A method for measuring the absorption of fluid in an absorbent product includes at least the following steps performed by a mobile device having an image capturing device: capturing at least one image of a used absorbent product; determining a measure of absorption of fluid by the product based on image information in the captured image; and displaying information relating to the use of the absorbent product based the measure of absorption of fluid on the mobile device. The method can aid a user of absorbent product to choose the right type of product for the user'"'"'s individual needs.

Claims

1. A method for measuring absorption of fluid in an absorbent product, comprising at least the following steps, performed by a mobile device comprising an image capturing device:

obtaining capacity information relating to an absorption capacity of the absorbent product by automatic retrieval of information from a product database;

capturing at least one image of a used absorbent product;

determining a measure of absorption of fluid by said used absorbent product based on image information in the captured image;

estimating, from said measure of absorption of fluid, an estimated amount of fluid absorbed by said used absorbent product,

comparing the estimated amount of absorbed fluid with the absorption capacity of said absorbent product, and

displaying information relating to the use of the absorbent product based on said measure of absorption of fluid on said mobile device, wherein said information is based on said comparison.

2. The method according to claim 1, wherein the information displayed comprises a recommendation to the user of said used absorbent product regarding a suitable absorbent product to use.

5. The method according to claim 1, wherein the capacity information is obtained from a user of the mobile device (1) in form of user input.

6. The method according to claim 1, wherein the step of obtaining capacity information comprises a step of automatically identifying an absorbent product in the field of view of the image capturing device, and obtaining the capacity information automatically from the product database.

7. The method according to claim 1, further comprising the step of illuminating the used absorbent product with an integrated light source of the mobile device during capturing of said at least one image.

8. The method according to claim 1, wherein the at least one image is a plurality of close-up images capturing different parts of the used absorbent product.

9. The method according to claim 1, wherein the at least one image is a plurality of images forming a video sequence captured by scanning the used absorbent product with the mobile device.

10. The method according to claim 1, wherein the method is performed on one or more real-time images of the used absorbent product.

11. The method according to claim 1, wherein the absorbent product is an absorbent personal hygiene article.

12. A non-transitory computer readable recording medium storing thereon a program for measuring the absorption of fluid in an absorbent product, wherein the computer program, when executed by a processor of a mobile device comprising an image capturing device, causes the mobile device to perform the method according to claim 1.

13. A mobile device that measures the absorption of fluid in an absorbent product, the mobile device comprising an image capturing device, a processor, and a computer readable recording medium storing the computer program according to claim 12.

14. The method according to claim 11, wherein the absorbent personal hygiene article is one of a male or female incontinence protector, a sanitary pad, a diaper with tape fastener, a pant diaper and a belted diaper.
