Extended Numerical Keyboard with Structured Data Entry
Message #1 Posted by Gordon Dyer on 10 May 2003, 2:48 p.m.

Here is a new method of number input to a calculator which has been patented. The link gives a working version of a java calc with this method of entry. I think it is well suited to financial calculators.
I would be interested to see opinions on the usefulness of this, particularly if combined with RPN.
