Abstract

Claims (68)

1. A method for generating an interface in a mobile or wearable device, the method comprising:

determining, over a period of time, a first set of a first amount of values of a gait attribute;

using an interpolation on the first set of the first amount of values to generate a second amount of numbers;

obtaining, using said second amount of numbers, a second set of the second amount of values representing colors;

creating an image composed of pixels, by assigning each one of the values representing colors to each one of the pixels of the image;

generating the interface that displays at least the created image.

2. The method of claim 1 , wherein the values of the gait attribute are determined with an update frequency greater than 3 Hz.

3. The method of claim 1 , wherein the second amount is greater than 3000, and wherein the mobile or wearable device is a smartphone.

4. The method of claim 1 , wherein the gait attribute is a length of a gait step.

5. The method of claim 1 , wherein the obtaining the second set of the second amount of values representing colors comprises: determining a parameter related to the first set of the first amount of values, and using said parameter to compute each one of the values representing colors.

6. The method of claim 1 , wherein the interface further displays additional metadata corresponding to the created image.

7. A method for generating an interface in a mobile or wearable device, the method comprising:

determining, over a period of time, a first set of a first amount of values of a gait attribute;

using an interpolation on the first set of the first amount of values to generate a second amount of numbers;

leveraging a matrix factorization on the second amount of numbers to generate and store a third amount of numbers;

retrieving from the stored third amount of numbers, an approximation of the second amount of numbers;

obtaining, using said approximation of the second amount of numbers, a second set of the second amount of values representing colors;

creating an image composed of pixels, by assigning each one of the values representing colors to each one of the pixels of the image;

generating the interface that displays at least the created image.

8. The method of claim 7 , wherein the values of the gait attribute are determined with an update frequency greater than 3 Hz.

9. The method of claim 7 , wherein the second amount is greater than 3000, and wherein the mobile or wearable device is a smartphone.
