1. An information processing system comprising:

  • a shock sensor;

    processing circuitry configured to, for each of plural shock events,receive input data from the shock sensor which outputs data defining a respective shock event,receive time-series data output from a motion sensor that senses motion of an object, the shock sensor having a greater dynamic range in acceleration than the motion sensor,set a length of a pre-shock portion of a target segment of the time-series data as a length of the longest pre-shock portion among plural predetermined motion patterns,set a length of a post-shock portion of the target segment as a length of the longest post-shock portion among the plural predetermined motion patterns,identify the target segment according to the defined respective shock event and the set lengths of the pre-shock portion and the post-shock portion,identify an impact position on the object, andidentify the motion of the object as one of the plural predetermined motion patterns based on the identified target segment of the time-series data and a stored dictionary defining each of the plural predetermined motion patterns; and

    a display configured to notify a user of the identified one of the plural predetermined motion patterns and display an impact position indicator on the object which is in an orientation corresponding to an actual orientation of the object at a time of impact based on the identified one of the plural predetermined motion patterns and the identified impact position.
