Numeric Keys With Cursor Move Function

      Disclosed is a design concept of allocating numeric keys
and cursor move keys on the same portion of a keyboard to reduce the
total space of a keyboard.

      Traditionally, numeric keys are allocated in a 3X3 matrix and
some more keys around it to get good perceptivity and good usability.
On the other hand, cursor move keys are usually allocated in the
cross (+) for the same purpose. These layouts have been well accepted
by users all over the world on the various types of devices.

      In this new layout keyboard design, numeric keys and cursor
move keys are allocated overlapping on the same portion of the
keyboard as shown in the figure by the extension keys, which have
nomenclatures of or.  When an operator presses a key, which has both
notations of numerics and cursor move, without pressing the extension
key, it works as a numeric key.  When an operator presses the same
key with pressing the extension key, it works as a cursor move key.

      Since operators perceive the 3X3 matrix of numeric keys as one
cluster and they perceive the cross (+) of cursor movement keys as
another cluster, this overlap allocation still keeps good
perceptivity and good usability.  By this method, keyboard designers
can reduce the total number of keys on their layout design, keeping
good perceptivity and good usability.

      This method will be helpful to design any small information
devices, which do not have enough s...
