Mobile Acoustic Pulse Recognition (APR) Components for Custom Handheld and Mobile Devices

Elo Acoustic Pulse Recognition (APR) touchscreens use a unique way of sensing touches on a display. Consisting of a glass overlay without an ITO (indium tin oxide) coating and with compact electronics, mobile APR provides a new set of benefits that have only been partially achieved before by other touch technologies.

APR combines the latest in optical quality with durability, stability, and smooth dragging properties for touch activation with any stylus, glove, bare finger and fingernail. It is well-suited for many diverse handheld and mobile applications including portable retail point-of-sale, medical, industrial and communication devices. Its pure-glass surface is resistant to scratches, water and other contaminants on the screen, and can be scaled from 2.5-inch to 7-inch screens for mobile devices. (APR technology is also available for touchmonitors up to 60" and touchcomputers.)

APR works in a simple and elegant way—by discriminating external noise factors and effectively recognizing the sound created when the glass is touched at a given position.
