Acoustic Wave (SAW) |
Surface Acoustic Wave technology is one of the most advanced touchscreen
types. It is based on sending acoustic waves across a clear glass panel
with a series of transducers and reflectors. When a finger touches the
screen, the waves are absorbed, causing a touch event to be detected
at that point. Because the panel is all glass there are no layers that
can be worn, giving this technology the highest durability factor and
also the highest clarity.
This technology is recommended for public information kiosks, computer
based training, or other high traffic indoor environments.
