[IxDA Discuss] "Interface-Free" Interface

[Juan Lanus]

These computers are an example of a keyboard and mouse less interface:

are Pentium PCs, compatible, regular.

Only they are usually operated thru the TFT screen in the places where
they are used, maily restaurants, casinos, and the like.

The "keyboard" appearing in the pictures is an image in the screen,
not actual keys. In the back of the PC there is a standard "ATX"
connector ribbon so regular keyboards and mpuses can be connected when
needed.

The size of the buttons is appropriate for the pointing device, the
pointing finger.
The applications behave well, topping the bills exactly.
This touch screens sense touch or no-touch, not pressure level.

As TFT panel prices continue to drop a bigger panel would be
affordable, maybe one with
an integrated keyboard in its bottom, when needed, and a
touch-pad-like surface there too.
Or maybe one of the kind of the laser keyboard:

There is no need for to exclude the input devices of today. What would
be the advantage, except for to trigger this thread?
