>Touch Screen A third party was showing a Decstation 3100 touch screen working at XHIBITION'90 in San Jose.....sorry...but the name escapes me. I remember seeing an ad in a rag recently too. Sorry.....try the ISVG folks ...they may have some info. | |||||
| 3070.2 | They have already touch screens ... | KETJE::PUTMANS | Close that Window, please | Fri Jul 13 1990 10:53 | 11 |
They have already touch-screens connected to their VAXstations but now they want to use the touch-facility :-) They would like to get rid of the mouse and connect the touch information (i think it's RS232) instead. what do they need to do ? thanks, Eric. | |||||

We have a 3100 fitted with a touch screen. The System we have uses a
serial `IntelliTouch' controller, and Xtouch s/w.
"Xtouch is a transparent touchscreen interface to X Windows. It
accomplishes this by way of mouse emulation. Applications using the
mouse for input can immediately take advantage of Xtouch using mouse
emulation".

What they say above is true, but...... don't forget that DECwindows was
not designed with touch screen in mind and what you'll find is that the
end of your finger is a rather crude instrument when it comes to
selecting items from pull downs etc. :-)
BTW this system sets up a sonic wave in the surface of the glass and
the disturbance caused by your finger is what does the work..... one
interesting and somewhat unexpected feature of this system is that it
supports Z axis as well as X and Y ! Pressing harder makes a
difference. (In the Mouse emulation s/w it is treated as MB1 down :-)
We have purchased this thing as part of our long term investigation
into Human Computer interaction, whether it will actually be appropriate
for your customers needs very much depends on exactly what they want to
do with it. (And the size of their fingers....)
