Abstract: A miniature keyboard wherein the keys are arranged in a way to improve data entry and decrease the chance of depressing multiple keys at a time. Accordingly, the height of the keys are patterned to decrease the chance of multiple key depressions thus increasing the accuracy of data input into the personal digital assistant. In one embodiment, the height of the keys is alternated down the individual rows of keys. In another embodiment, the height of the keys is alternated across individual columns of keys. Similarly, in another embodiment, the heights of the keys are arranged in a checkered pattern on the keyboard. In addition, another embodiment staggers the heights of the keys and incorporates embodiments mentioned above. By incorporating different key arrangements and alternating the height of the keys, key differentiation, key navigation, and data input accuracy is greatly improved due to the improved tactile feedback provided by the miniature keyboard.

Abstract: A keyboard allowing typists to use approximate QWERTY finger movements on a more compact, collapsible, and portable keyboard. The keyboard size is made more compact by using thin capacitance-responsive surfaces as key switches for the rows above and below the home row.

The capacitance-responsive surface for the row of keys switches above the home row has a convex profile, and the capacitance-responsive surface for the row of keys switches below the home row has a concave profile, such that the keyboard can fold compactly upon itself. The home row retains depressible key switches in order to provide standard rest positions for the fingers. Characters and commands assigned to the rows above and below the home row are engaged by sliding the fingers over the capacitance-responsive surfaces adjacent to the home row.
