Abstract

A system for transitioning from a first footwear type to a second footwear type is usable with an article of footwear including a sensor system with a plurality of force sensors engaged with an article of footwear and configured to sense force exerted by a foot of a user and an electronic module configured to collect data based on force input from the sensors and to wirelessly transmit data generated by the sensor system. An electronic device includes a processor that receives the data from the electronic module, compares the data to a footstrike template corresponding to a desired footstrike pattern of a footwear transitional program, determines whether a deviation from the footstrike template exists, and generates an indication to the user when the deviation from the desired footstrike pattern is determined to exist. The desired footstrike pattern corresponds to a preferred footstrike of the second type of footwear

Claims

1. A computer-assisted method of transitioning from a first footwear type to a second footwear type, comprising:

receiving data, at a processor of an electronic device, from a sensor system configured to sense biomechanical movement of a foot of a user during an athletic activity, the sensor system comprising an electronic module configured to wirelessly transmit data generated by the sensor system, and wherein the data is received from the electronic module;

analyzing the data, by the processor, to determine whether a deviation from a desired footstrike pattern corresponding to the second footwear type exists; and

generating an indication to the user, by the processor, upon completion of the athletic activity.

2. The method of claim 1, further comprising:

recording a plurality of data points of the user during an athletic activity session; and

providing feedback to the user based on data recorded during the athletic activity session.

3. The method of claim 2, wherein providing feedback to the user includes providing a suggested activity report for a subsequent athletic activity.

4. The method of claim 2, further comprising:

recording a plurality of athletic activities of a user; and

modifying a duration of the transitional program based on at least one of an amount of recorded deviations, a total time of recorded data, and a total distance of recorded data.

5. The method of claim 1, wherein the deviation is determined to exist if the degree of deviation is determined to exceed a predetermined threshold.

6. The method of claim 1, wherein the indication comprises at least one of a number and degree of deviations during the athletic activity, a suggested stretching activity, and a suggested activity report for a subsequent athletic activity

7. The method of claim 1, further comprising generating an alert to the user when a number of recorded deviations exceeds a predetermined deviation count threshold.

8. The method of claim 1, wherein comparing the data to the footstrike template includes:

detecting a footstrike pattern based on analysis of the data; and

comparing the footstrike pattern to the footstrike template.

9. The method of claim 8, wherein the plurality of sensors are located in different locations on the article of footwear, and wherein the footstrike pattern is detected based on at least one of a sequence of the forces sensed by the sensors and a level of the forces sensed by the sensors.

10. The method of claim 9, wherein the plurality of sensors are further configured to measure a pressure distribution under the foot and the electronic device is further configured to compare pressure distribution data to a foot pressure template.

11. The method of claim 1, wherein generating the indication includes transmitting a signal to a second electronic device, and wherein the signal is configured to cause the second electronic device to generate the indication.

12. A non-transitory computer-readable medium storage medium storing computer readable instructions that, when executed, cause a processor to perform a method comprising:

receiving data from a sensor system configured to sense biomechanical movement of a foot of a user, the sensor system comprising an electronic module configured to wirelessly transmit data generated by the sensor system, and wherein the data is received from the electronic module;

detecting a footstrike pattern based on analysis of the data;

comparing the footstrike pattern to a desired footstrike pattern corresponding to a footwear type to determine whether a deviation from the desired footstrike pattern exists; and

generating an indication to the user when the deviation from the desired footstrike pattern is determined to exist

13. The non-transitory computer readable storage medium of claim 12, further comprising computer readable instructions that, when executed, cause a processor to perform:

recording a plurality of data points of the user during an athletic activity session; and

providing feedback to the user based on data recorded during the athletic activity session.

14. The non-transitory computer readable storage medium of claim 12, further comprising computer readable instructions that, when executed, cause a processor to perform:

recording a plurality of athletic activities of a user; and

modifying a duration of the transitional program based on at least one of an amount of recorded deviations, a total time of recorded data, and a total distance of recorded data.

15. The non-transitory computer readable storage medium of claim 12, wherein the deviation is determined to exist if the degree of deviation is determined to exceed a predetermined threshold.

16. The non-transitory computer readable storage medium of claim 12, wherein the indication includes a degree of deviation from the desired footstrike pattern.

17. The non-transitory computer readable storage medium of claim 12, further comprising computer readable instructions that, when executed, cause a processor to perform generating an alert to the user when a number of recorded deviations exceeds a predetermined deviation count threshold.

18. The non-transitory computer readable storage medium of claim 12, further comprising computer readable instructions that, when executed, cause a processor to perform:

recording the data and

providing a summary of recorded data to the user.

19. The non-transitory computer readable storage medium of claim 12, wherein generating the indication includes transmitting a signal to a second electronic device, and wherein the signal is configured to cause the second electronic device to generate the indication.

20. A computer-assisted method of transitioning from a first footwear type to a second footwear type, comprising:

receiving, at a processor of an electronic device, a selection of a footwear transitional program including one or more desired footstrike patterns

receiving, at the processor, data from a sensor system configured to sense biomechanical movement of a foot of a user during an athletic activity, the sensor system comprising an electronic module configured to wirelessly transmit data generated by the sensor system, and wherein the data is received from the electronic module;

detecting a footstrike pattern based on analysis of the data;

comparing the footstrike pattern to a desired footstrike pattern of the footwear transitional program to determine whether a deviation from the desired footstrike pattern exists; and

generating an indication to the user, by the processor, upon completion of the athletic activity.
