ABSTRACT:
A keyboard for data entry or control purposes includes a plurality of sets of two or more keys arranged for receving the tips of the finger of a hand of an operator, the keys of each set have such a small superfical touch area and are clustered together so as to be substantially comprehended and selectively operated by a single finger tip of an operator. Additional keys having their superficial touch area spaced from but sufficiently close to the superficial touch area of a set of the sets may be provided to be conveniently operable by a finger tip of user operating the keys of the adjacent set. In a preferred embodiment of the invention, the superficial touch area of each key takes the form of a roller and each set of keys is made up of two keys. In some embodiments, the relative spacing between sets of keys or between keys may be adjustable.
