MultiTouch
technology comprises hardware and software elements for
sensing, tracking, and interpreting the motion of multiple
hands and multiple fingers on a touch imaging surface.
As a computer interface, MultiTouch is used to enable
regular typing, mouse, and gesture input in the same overlapping
area of a single surface. MultiTouch can also accept hand
written input using a stylus or a fingertip. With MultiTouch,
all of the important input modes with the exception of
voice (i.e., handwriting, typing, mouse, gesture, force,
and attitude) are satisfied with a single sensing surface.
The
MultiTouch sensor array is deposited on a flexible or
rigid surface that can be made in arbitrary shape, size,
and thickness. It has the potential to be manufactured
on thin and flexible plastic substrates using extremely
low cost methods such as web and roll processing.
This is image data captured using
a low resolution MultiTouch Surface (area: 180 x 400 sq
mm). Image frames are generated between 50 and 200 times
per second.
