ABSTRACT:
A compact stylus keyboard assembly includes a generally planar upper surface formed by a plurality of adjacently positioned, co-planar, electrically conductive key members which together form a keyboard. A hand-held stylus member is used to lightly touch and couple a predetermined voltage to each of individual key members of the keyboard. The key members are individually responsive to the predetermined voltage and provide a computer with a signal when coupled to the voltage. Each of the key members are hexagonal shaped and electrically isolated by an electrical insulating material in the form of a honeycomb pattern. The stylus member is generally T-shaped in cross section with a first, contact end and a second, opposite, end for facilitating single handed gripping and operation. The stylus member includes depressible switches that are operated by the operator's digits for providing modifying functions such as shift, control, and alternate while the stylus member is touching the key members. The stylus member enables an operator to grip the stylus member with a single hand such that the key members may be touched one by one, or the operator may manually slide the stylus member upon the planar upper surface of the keyboard across desired key members and the electrical insulating material therebetween in order to provide the computer with a sequence of key signals.
