The Patent Office has issued a patent for John Dargan's latest system for interacting with computers via the Touch-Tone keypad. With the Dargan algorithm text messages
can be entered on a reduced keypad more efficiently.
The algorithm has been independently tested. The test concluded: "the Exponent Group Trust algorithm
is superior to the functionality of the typical mobile phone keypad algorithms in use for text messaging
purposes." This algorithm can be incorporated into individual programs. The algorithm is:
• Available for license at reasonable terms
• U.S. Patent
