PCT No. PCT/IL96/00078 Sec. 371 Date Feb. 11, 1998 Sec. 102(e) Date Feb. 11, 1998 PCT Filed Aug. 12, 1996 PCT Pub. No. WO97/08603 PCT Pub. Date Mar. 6, 1997A method for operating a computer by means of a pointer comprises providing counters for memorizing coordinate displacements of the pointer index; choosing one of two modes, the REGISTER OR MEMORY (R/M) mode or the ACTIVE OR PLAY (A/P) mode; when in the R/M mode, moving the pointer index from a selected base point to a reference position corresponding to a computer operation, and memorizing the resulting pointer index displacements; and when the pointer in the A/P mode, bringing the pointer index to the base point, applying to it the memorized displacements, thus moving it from the base point to the reference position, and carrying out the operation corresponding to this latter. A computer apparatus comprises, in addition to the conventional elements of a pointer operated computer, counters for registering differential displacements and means for retrieving from the counters the registered differential displacements and applying them to a base position of the pointer. The nonconventional elements of the apparatus are preferably included in the pointer or part of an Asynchronous Interface. |
