A method and a pointing device are provided for reporting a movement amount of
an operation instrumentality of the pointing device. A first value representing
the movement amount in a first direction is examined. Whether scaling should be
performed is determined based on the first value. When it is determined that scaling
is to be performed, the first value is scaled by a first scaling factor and a first
scaling indicator is set to indicate that the first value is scaled by the first
scaling factor. Reporting information is then output, including the first value
if scaling has not been performed, and when scaling has been performed, the reporting
information includes the scaled first value and the first scaling indicator. The
first value may be scaled by one of a plurality of scaling factors selected based
on the first value.
