1. A computer-implemented method comprising:
- receiving, by a computing device, information identifying a plurality of events detected from one or more sensor signal streams during performance of a physical activity by a user;
evaluating, by the computing device, the plurality of events against one or more constraints of the first action template;
determining whether the plurality of events matches the first action template based on the evaluation of the plurality of events against the one or more constraints of the first action template; and
in response to determining that the plurality of events matches the one or more constraints of the first action template, registering user performance of a first type of action corresponding to the first action template.

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.

15. One or more non-transitory computer readable media storing computer readable instructions that, when executed, cause an apparatus to process a physical activity action template, the physical activity action template storing:
-
a plurality of required states; and for each of the plurality of required states, a state-specific set of one or more constraints defining match characteristics of a corresponding required event, 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. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)

24. An apparatus comprising:
-
a processor; and memory storing computer readable instructions that, when executed, cause the apparatus to; receive information identifying a plurality of events detected from one or more sensor signal streams during performance of a physical activity by a user; evaluate the plurality of events against one or more constraints of the first action template; determine whether the plurality of events matches the first action template based on the evaluation of the plurality of events against the one or more constraints of the first action template; and in response to determining that the plurality of events matches the one or more constraints of the first action template, register user performance of a first type of action corresponding to the first action template.
