Abstract

Activities, actions and events during user performance of physical activity may be detected using various algorithms and templates. Templates may include an arrangement of one or more states that may identify particular event types and timing between events. Templates may be specific to a particular type of activity (e.g., types of sports, drills, events, etc.), user, terrain, time of day and the like.

First claim

What is claimed is:

1. A system, comprising:
a sensor system including a plurality of sensors, at least a first processor and at least a first memory storing computer-executable instructions that, when executed, cause the sensor system to:
receive, from the plurality of sensors, raw athletic activity data associated with a potential corresponding event during performance of an athletic activity;
process the raw athletic activity data;
transmit, from the sensor system to an activity processing system, the processed athletic activity data, transmitting the processed athletic activity data to an activity processing system including controlling, by the sensor system, at least one of a type of data and an amount of data transmitted, wherein the type of data or amount of data transmitted is controlled based on a sensor subscription;
the activity processing system including at least a second processor and at least a second memory storing computer-executable instructions that, when executed, cause the activity processing system to:
receive, from the sensor system, the processed athletic activity data;
compare the received processed athletic activity data to a plurality of physical action templates to determine whether a physical activity of at least one physical action template of the plurality of physical action templates has occurred, the comparing including:
determining a plurality of required states associated with the physical activity of the at least one physical action template and forming a portion of the at least one physical action template;
for each of the plurality of required states, determine a state-specific set of one or more constraints defining match characteristics of a corresponding required event,

determine, based on the comparison, a match score for the one or more constraints;
determine, based on the match score, whether the physical activity has occurred; and
transmit a result of the determining whether the physical activity has occurred to one or more devices.

2. The system of claim 1 , wherein the sensor subscription is determined based on identification of a type of athletic activity performed.

3. The system of claim 1 , wherein a state-specific set of one or more constraints for a first state of the plurality of required states includes a relative constraint defining a required relationship between the first state and a second state of the plurality of required states, and
wherein the state-specific set of one or more constraints further includes a scoring distribution for determining the match score for the one or more constraints.

4. The system of claim 3 , wherein the state-specific set of one or more constraints further includes a first parameter indicating whether a first characteristic of the corresponding event is to be scored.

5. The system of claim 1 , wherein the state-specific set of one or more constraints further includes a second parameter indicating whether a second characteristic of the corresponding event is to be scored.

6. The system of claim 1 , wherein the state-specific set of one or more constraints includes at least one of: an event occurrence time stamp constraint, an event generation time stamp constraint, an event value constraint and an event duration constraint.

7. The system of claim 1 , wherein the one or more devices include a remote activity tracking system.

8. The system of claim 1 , further including instructions that, when executed, cause the first processor to:
responsive to determining, based on the match score, that the physical activity has occurred, displaying that a user has performed the physical activity corresponding to the at least one physical action template on a display of the one or more devices.

9. The system of claim 1 , wherein the plurality of sensors are arranged in at least one of: an article of apparel, an article of footwear, and a wrist-borne device.

10. One or more non-transitory computer readable media storing computer readable instructions that, when executed, cause a processor to:
receive, by a sensor system having a plurality of sensors and from the plurality of sensors, raw athletic activity data associated with a potential corresponding event during performance of the athletic activity;
process the raw athletic activity data;
transmit, from the sensor system to an activity processing system, the processed athletic activity data, transmitting the processed athletic activity data to the activity processing system including controlling, by the sensor system, at least one of a type of data and an amount of data transmitted, wherein the type of data or amount of data transmitted is controlled based on a sensor subscription;
receive, by the activity processing system, the processed athletic activity data;
compare, by the activity processing system, the received, processed athletic activity data to a plurality of physical action templates to determine whether a physical activity of at least one physical action template of the plurality of physical action templates has occurred, the comparing including:
determining a plurality of required states associated with the physical activity of the at least one physical action template and forming a portion of the at least one physical action template;
for each of the plurality of required states, determine a state-specific set of one or more constraints defining match characteristics of a corresponding required event;

determining, based on the comparison, a match score for the one or more constraints;
determining, based on the match score, whether the physical activity has occurred; and
transmitting a result of the determining whether the physical activity has occurred to one or more devices.

11. The one or more non-transitory computer readable media of claim 10 , wherein the sensor subscription is determined based on identification of a type of athletic activity performed.

12. The one or more non-transitory computer readable media of claim 10 , wherein a state-specific set of one or more constraints for a first state of the plurality of required states includes a relative constraint defining a required relationship between the first state and a second state of the plurality of required states,
wherein the state-specific set of one or more constraints includes at least one of: an event occurrence time stamp constraint, an event generation time stamp constraint, an event value constraint and an event duration constraint, and
wherein the state-specific set of one or more constraints includes different scoring distributions for each of the at least one of: the event occurrence time stamp constraint, the event value constraint, the event generation time stamp constraint and the event duration constraint.

13. The one or more non-transitory computer readable media of claim 10 , wherein the physical activity action template further stores one or more exclusion state constraints configured to exclude the potential corresponding event from being identified as potential matches with one or more of the plurality of required states when the potential corresponding event is determined to match the one or more exclusion state constraints.

14. The one or more non-transitory computer readable media of claim 10 , wherein the one or more devices include a remote activity tracking system.

15. The one or more non-transitory computer readable media of claim 10 , further including instructions that, when executed, cause the processor to:
responsive to determining, based on the match score, that the physical activity has occurred, displaying that a user has performed the physical activity cor
