Abstract

A 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.

C--when the pointer is in the A/P mode;

(I) selecting an operation unit from one previously selected in the R/M mode;

(ii) determining the corresponding counter coordinates of the reference position by applying the differential coordinate displacements, with the appropriate sign, to the counter coordinates of a second base point; and

2. Method according to claim 1, wherein the first and second base points coincide.

3. Method according to claim 2, wherein the base point is an arbitrarily chosen point.

4. Method according to claim 2, wherein the base point is a position which the pointer index occupies or has previously occupied and the coordinates of which have been memorized.

5. Method according to claim 2, for performing a multi-phase operation or a program, which includes a plurality of operation units in which the displacements are counted by:

a) bringing the pointer index to any selected base point, b) displacing the pointer index and counting displacements starting from said base point until the first reference position, relative to the first operation unit, has been reached, c) registering said first counted displacements, d) displacing the pointer index and continuing to count displacements from said first reference position until the second reference position, relative to the second operation unit, has been reached;

e) registering said second counted displacements; and

so on, displacing the pointer index from one reference position to the next and counting the respective displacements, until the last reference point, relative to the last operation unit, has been reached.

6. Method according to claim 5, further comprising disregarding the displacement from the base point to the first reference position, when in the R/M mode.

7. Method according to claim 5, wherein commands may be given by the pointer between stages and when the pointer is in the R/M mode, said pointer commands are caused to be registered.

8. Method according to claim 1, wherein the base point is the actual position of the pointer index.

continuing to count the displacements as long as the computer is in operation; and

assuming the displacements counted from any given reference position up to any moment as the differential displacements relative to said reference position and a base point that is the position in which the pointer index finds itself at that particular moment.

10. Method according to claim 8, for performing a multi-phase operation or a program, including a plurality of operation units, which comprises arranging the operation units and the corresponding reference points in a succession, and assuming each reference point as the base point relative to the next reference position.
