1. An information processing system, comprising:

  • a plurality of portable communication devices; and

    an information processing device for indoor use that is communicatively connectable to the plurality of portable communication devices, wherein;

    each of the plurality of portable communication devices comprises a sensor that measures an orientation of the portable communication device, and outputs measurement results, the sensor having output characteristics causing the measurement results to vary in response to one or more sources of ambient interference within a given place of use of the portable communication device; and

    the information processing device comprises;

    a section for acquiring the measurement results of the sensors from the communicatively-connected portable communication devices;

    a calibration section for executing calibration of the sensors by using the acquired measurement results;

    an application execution section for executing an application program that receives the measurement results of the sensors as user-initiated inputs for manipulating outcomes of the application program during execution of the application program;

    a flag information storing section for storing respective flag information when the calibration section executes the calibration, each flag information indicating whether or not the information processing device has executed the calibration for respective ones of the plurality of portable communication devices, and the flag information storing section storing the respective flag information in a storage unit in association with the respective portable communication devices; and

    a determination section for performing respective determinations as to whether or not the calibration section has executed the calibration for respective ones of the plurality of portable communication devices by referencing the respective flag information in the storage unit, the respective determinations being made at a time after the application execution section opens and starts executing the application program and before the application program receives the measurement results of the sensors as the user-initiated inputs for manipulating outcomes of the application program during execution.
