Abstract
A hand held data entry system (100, 100') has an ergonomic housing (102) including upper surface controls (104) which generate a first set of electrical signals, and lower surface controls (106) which generate a second set of electrical signals when operated independently. The first set of electrical signals and second set of electrical signals define all of the lower case alphabetic characters of an alphabet, such being generated without the user having to remove a finger or thumb from a HOME switch operator or grouping. Each side of the housing (102) is provided with a recess (120) for contiguous contact with a first dorsal interosseous portion of the user's hands, providing support for housing (102) while the user's fingers and thumbs operate the switch operators which make up the upper surface controls (104) and the lower surface controls (106).
