Abstract

A keyboard utilizing a matrix arrangement of word, character, numerical (print medium) keys to enhance a standard print medium keyboard. Instead of utilizing keys with letters and numbers, and instead of utilizing iconic symbols (or for use in combination with iconic symbols), the keyboard includes a plurality of keys arranged in at least two matrices. The keys of the first matrix are associated with each other in some manner, as are keys in at least one additional matrix. The matrices can include keys grouped together and grammatically associated with one another, by part of speech for example; and/or can include keys associated with a common color and a common number of selections necessary to access an associated word or word phrase. By use of such a keyboard, preferably in conjunction with a word output device, both manual and scanning input can be enhanced in a print medium environment, without the need to invest substantial time in memorizing complex iconic structures.
