1. An interactive sports ball comprising:
a body;
a sensor arrangement having
a first sensor, embedded within the body, to measure acceleration data associated with the ball, and
a second sensor, embedded within the body, to measure rotational data associated with the ball; and
a communication module operatively coupled to the sensor arrangement and configured to transmit the measured acceleration and rotational data to a processing unit, wherein the measured acceleration and rotational data is received and processed by the processing unit to:
generate a series of sequential measurements corresponding the measured acceleration and rotational data,
calculate a variance using a set of sequential measurements from the series of sequential measurements, and
detect a contact event if the calculated variance exceeds a predefined event threshold; and the processing unit is configured to select the set of sequential measurements from the series of sequential measurements based on a dynamic sliding window.
