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.
