A computer pen that does not require any reference point to be touched or active matrix or the interruption of a field to know its present positioning. It is fitted with a standard retractable pen refill (51). It can be used for normal screen cursor control with or without reference to a substrate, can be used as a digitiser without reference to a tablet, can be used as a writing or drawing implement on any normal writing surface, and concurrently send back positional X and Y co-ordinate information through circuitry and microprocessors (56) to the computer via a cable (55) to give an accurate representation of the writing or drawing. Its absolute positioning is derived without recourse to a spatial frame of reference through the use of peizo ceramic bimorphic bender sensors (50) and Hall effect and rotational sensors (59) housed in the top and bottom of the pen body (52). <IMAGE> |
