Abstract: A data-collecting play object. The play object includes a body manipulated by a player. A data-collecting unit is disposed in the interior of the body. The data-collecting unit includes an accelerometer unit measuring acceleration values along at least one translational degree of freedom, a gyroscope unit measuring rotation values about at least one rotational degree of freedom, and a processor in communication with the accelerometer unit and with the gyroscope unit. The processor obtains the acceleration values from the accelerometer unit and the rotation values from the gyroscope unit. The processor wirelessly transmits the acceleration and rotation values at discrete intervals. A power source supplies electrical power to the accelerometer unit, the gyroscope unit, and the processor. The play object being used in combination with an identification tag attached to a play accessory is also disclosed. A system and a method are also disclosed.
