Abstract: A computer controlled pointing device having, a telescoping wrist support integral with and associated with the pointing device, so as to permit adjustable extension and retraction from the pointer device housing, to accommodate the preferred support position of an individual user's wrist. The means from effecting such adjustable incremental extension and retraction of the wrist support includes coupling means for releasable locking of the wrist support in a fixed position relative to the housing of the pointing device.
