Acoustic Pulse Recognition Touch Technology
Elo Acoustic Pulse Recognition (APR) touchscreens use a completely new and unique way of sensing touches on a display. Consisting only of a glass overlay mounted in front of the display, together with a small electronic controller board, APR technology provides a new set of benefits that have only been partially achieved before by other touch technologies.
APR combines the ultimate in optical qualities, durability, and stability, with excellent dragging properties. By combining stylus, glove, bare finger and fingernail activation, with low-cost advantages, APR is well-suited for many diverse applications including kiosk, point-of-sale and medical instrumentation. In addition, it's pure-glass surface is resistant to scratches, water and other contaminants on the screen, and can be scaled from 2.5-inch to 42-inch displays.
APR works in a simple and elegant way—by recognizing the sound created when the glass is touched at a given position.
NOTE: The Acoustic Pulse Recognition touch technology is not supported by all operating systems. See the Technology notes for each driver on the Driver and File Downloads page to verify support for your touchscreen technology.
