I looked for experiences with touch screens too, so I > thought my mail in questions was not out of topics. I've used touch screens before, but we had DOS PCs front-ending the application. Each PC was embedded in a console and controlled two large screens (54" diagonal in the small briefing rooms, and 100" diagonal in the large auditorium), four smaller monitors (either 27" or 37"), two SGI workstations, and an amazing variety of video sources, including a digital camera and professional beta video tape, through a complicated video switch. The switch could put any source on any destination, or split the large monitors into four windows and display four sources simultaneously on each large monitor. The touch screen was the weakest link in the entire system. The program that was supposed to calibrate the touch screen failed about 75% of the time, and if it didn't fail, the "registration" on the touch screen would wander enough that by the end of a 1-hour briefing the user was guessing what to touch to get the screen he wanted. I hope your friend has better luck. The site I dug up *did* offer UNIX drivers; if they are willing to give out the source, it might be fairly easy to adapt them to FreeBSD. They might be more willing to give your friend the source if he offers to contribute the results to the FreeBSD project, or back to the manufacturer. ;^) -- "Where am I, and what am I doing in this handbasket?"
