Abstract
An ergonomic keyboard entry system (100) is provided. The system (100) includes a base (200) on which is provided a set of first control keys (120) for assigning an output function selected by simultaneously operating one of a plurality of multifunction character keys. In particular, alphabetic character output functions are selected utilizing one of a set of first character keys (220), the particular assignment of alphabetic characters to the particular character keys (222, 224, 226, 228 and 230) being made to provide QWERTY compatibility. Each of the sets of keys (120, 220) are irregularly arranged on the base (200) to be located under the fingertips of a user's bent hands. Further, each of the sets of keys (120, 220) are configured about respective axes (276, 286 and 278, 288), the two axes being disposed at different angles with respect to a horizontal reference, permitting a miniaturized keyboard to be implemented with full size keys.
