ABSTRACT:
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.
