I’ve just heard that guided acoustic wave touchscreens are available
now. We had planned on using these a couple of years ago, but the
patent owner, Carroltouch, was owned by Amp, which in turn was tied up
in a takeover battle. The technology was tied up for a long time, but
apparently now it is owned by Elographics.
We had been using the Elo resistive touchscreens, but they have proven
to be unsatisfactory. Our supplier claims that the GAW touchscreens use
the same protocol, smartset, that the resistive devices use. This is
supported by Photon 1.13, and we would like to just substitute the new
technology for the old without having to do a software distribution. My
question is, has anyone out there used the GAW devices, and do they
indeed use the same protocol as the resistive screens? We plan on
trying a prototype, of course, but any comments would be appreciated.
