Abstract

A display system for an article of footwear includes a display device with an optoelectronic display, a control module that is configured to communicate with the display device, and a power source. The display system has a visual characteristic that is configured to correspond with a gait cycle of a user wearing the article of footwear.

First claim

We claim:

1. A display system for an article of footwear, the display system comprising:
a display device with an optoelectronic display that includes electrophoretic ink;
a control module that is configured to communicate with the display device; and
a power source, wherein a visual characteristic of the display device is configured to correspond with a gait cycle of a user wearing the article of footwear,
wherein the gait cycle includes a stance phase, in which the article of footwear contacts a ground surface, and a swing phase, in which the article of footwear does not contact the ground surface,
wherein the stance phase includes at least two subphases,
wherein the visual characteristic includes at least two different states that correspond with the at least two subphases of the stance phase, and
wherein the visual characteristic is at least one of: a symbol, text, an image, or an animation.

2. The display system of claim 1 , wherein the visual characteristic is further comprising at least one of: a color, a transparency, a gloss unit, a power level, or a pattern.

3. The display system of claim 1 , wherein the electrophoretic ink is integrally formed with an upper of the article of footwear.

4. The display system of claim 1 , wherein the display device is arranged on an upper of the article of footwear.

5. An article of footwear, comprising:
a sole attached to an upper; and
a display system, including:
a display device with an optoelectronic display that includes electrophoretic ink, the display device being arranged on the upper;
a control module that is configured to communicate with the display device;
a power source; and
a sensor in electrical communication with the control module,

wherein a visual characteristic of the display device is configured to correspond with a gait cycle of a user wearing the article of footwear,
wherein the gait cycle includes a stance phase, in which the article of footwear contacts a ground surface, and a swing phase, in which the article of footwear does not contact the ground surface,
wherein the control module is configured to, in response to signals received from the sensor, cause the display device to change between one or more different states,
wherein the sensor is configured to be deformable when the upper deforms throughout the gait cycle,
wherein the stance phase includes at least two subphases,
wherein the visual characteristic includes at least two different states that correspond with the at least two subphases of the stance phase, and
wherein the visual characteristic is at least one of: a symbol, text, an image, or an animation.

6. The article of footwear of claim 5 , wherein the control module is disposed within a midsole of the sole.

7. The article of footwear of claim 5 , wherein the electrophoretic ink is integrally formed with the upper.

8. The article of footwear of claim 5 , wherein the sensor is configured to measure at least one of the following of the article of footwear: a number of gait cycles taken, a velocity, an acceleration, or an intensity of ambient light.

9. The article of footwear of claim 5 , wherein the sensor is external to the article of footwear.

10. The article of footwear of claim 5 , wherein the sensor is arranged in the sole of the article of footwear.

11. The article of footwear of claim 10 , wherein the sensor is configured to measure pressure exerted on an insole of the sole.

12. The article of footwear of claim 5 , wherein the article of footwear is a first article of footwear of a pair of footwear, the display system is a first display system, the control module is a first control module, and the visual characteristic of the first display system is a first visual characteristic that is configured to correspond with a gait cycle of a first foot of the user,
wherein the pair of footwear further includes a second article of footwear that comprises a second display system, and
wherein a second visual characteristic of the second display system is configured to correspond with a gait cycle of a second foot of the user.

13. The article of footwear of claim 12 , wherein the second article of footwear further comprises a second control module, and
wherein the first and second control modules are configured to be in electrical communication with an electronic device external to the pair of footwear.

14. A display system for an article of footwear, the display system comprising:
a display device that includes an optoelectronic display with electrophoretic ink;
a control module that is configured to communicate with the display device;
a power source, wherein a visual characteristic of the display device is configured to correspond with a gait cycle that includes a plurality of gait subphases; and
a sensor in electrical communication with the control module,
wherein the visual characteristic includes at least three different states that correspond to at least three different subphases of the gait cycle,
wherein the control module is configured to, in response to signals received from the sensor, cause the visual characteristic of the display device to change between the at least three states,
wherein at least two of the at least three different subphases are in a stance phase of the gait cycle, in which the article of footwear contacts a ground surface, and
wherein the visual characteristic is at least one of: a symbol, text, an image, or an animation.

15. The display system of claim 14 , wherein the visual characteristic is further comprising of at least one of a color, a transparency, a gloss unit, a power level, or a pattern.

16. The display system of claim 14 , wherein the control module is configured to provide a first electrical signal or a second electrical signal to the display system, the first electrical signal causing the display system to be in a first state of the at least three states and the second electrical signal causing the display system to be in a second state of the at least three states.

17. The display system of claim 14 , wherein the control module is configured to receive a user input, such that the visual characteristic is customizable by a user via the user input.
