ABSTRACT:
A typewriter instruction device is provided wherein the student has small ferromagnetic tips at the ends of his fingers while the typewriter keys have electromagnets which attract the student's correct finger when an instruction to type a certain key is given. In accordance with a preferred embodiment of the invention, permanent magnets are employed at the fingertips with alternating polarities on adjacent fingertips, while the electromagnets have reversed alternating polarities, so that the correct finger is not only attracted to the proper key but adjacent fingers are actually repelled.
