What was I thinking!!!
That is total nonsense. Touch-pads are not vector devices. You cannot 'draw a
line' on a tablet. Clever clogs programmers weave their magic and make Apple
fanbois think that they can.
OK, that was a bit harsh.
The touch-pad technology sends all of the x-y co-ordinates triggered by touch to
the computing device. The software has to calculate the centre of the shape of
the touch-area. In a painting program, this is taken as the centre point of the
brush.
Swiping gestures must be analysed from the rate of change of the co-ordinates of
the centre-of-touch point. X co-ordinates are used for the X-axis swipes and Y
co-ordinates for the Y-axis. The multiple-touch screen technology and software
are truly neat.
For the virtual-keyboard invention to be implemented on a touch-pad, the
software only has changing X-Y co-ordinates to work with. It is worthless, in
computing terms, to convert the X-Y co-ordinates into vectors, because the
processor cannot easily manipulate binary symbols representing lines with
angles.
To implement the invention as defined would take a top-of-the-range Intel
processor. Only by discarding all the elements of the invention and substituting
existing virtual keyboard technology can the invention appear to work on the
touch-pad technology available, today.
In other words, software can make it appear to the user that the patent had been
implemented, but the 'for the purpose of' has been met by existing software and
hardware technology.
The touch-pad manufacturer can be sued because the 'for the purpose of' patented
idea has been implemented in the touch-pad device by the software writer.
