This article answers a common customer question about whether Elo offers Projected Capacitive, also known as PCAP, touchscreen monitors that are limited to single-touch operation.

Applies To:

• Elo PCAP touchscreen monitors
• Customers asking for single-touch PCAP operation
• Windows systems using the Elo touch driver

Why PCAP Is Not Sold as Single-Touch

PCAP touchscreen technology is designed to detect touch through a sensor grid built into the glass. That design allows the touchscreen controller to detect more than one point of contact at the same time.

Because of this, PCAP technology is inherently multi-touch. It is not manufactured as a true single-touch hardware solution in Elo's PCAP monitor lineup.

This is different from some older touch technologies, such as resistive or surface acoustic wave, which were commonly available in single-touch versions.

What To Do If Single-Touch Operation Is Required

If an application requires only one touch point, Elo provides a way to limit touch input to a single touch point by using the Elo Windows Touch Driver.

This does not convert the touchscreen into a true single-touch hardware device. Instead, it limits the touch input reported to the operating system.

How To Enable Single-Touch Mode

If single-touch behavior is needed on a supported Windows system, follow the steps in the article below:

Summary

• Elo does not sell true single-touch PCAP monitors.
• PCAP technology is designed as multi-touch by nature.
• If single-touch operation is required, the Elo Windows Touch Driver can be used to limit input to a single touch point on supported systems.
