ABSTRACT:
A computer input device for positioning a cursor on a computer video screen. With this device information is put into the computer by the penmanship motion of the hand holding a stylus in the fashion of a writing instrument so that only finger motion is required for data input. Device replaces the arm-to-eye coordination of the mouse with hand-to-eye coordination such as that used in ordinary penmanship. Rather than encoders driven by a turning ball or wheels, a resistance array with wiper contacts produces variable resistances which are converted into variable voltages that are a function of position of the stylus.
