Touchscreens
There are two types of touchscreens for the NCR XL15 (5915):
• Projected Capacitive (PCap) Touchscreen
• Resistive Touchscreen
Projected Capacitive Touchscreen
PCap touchscreens have all the benefits of normal capacitive touchscreens and more.
• Fast processing of tough information
• High sensitivity (use conductive pencils, with hands, and with thin gloves.
• Multi-touch capability (10-finger)
• High resolution
• Improved legibility and display brightness due to optimal light transmission
In addition, the technology of PCap touchscreens is characterized by significantly
higher robustness and stability than common capacitive touchscreens because the active
touch surface is located on the back side of the touchscreen. instead of the front side.
Therefore, the active surface is not directly touched and does not wear off by normal
use.
Since most surface contamination do not cause interference to the touchscreen the NCR
XL15 (5915) can be used in public or severe environmental conditions.
Using the PCap Touchscreen
The PCap touchscreen responds to the lightest touches. Touching with a single finger
resembles the left mouse button. Two fingers are used to zoom IN (fingers brought
together) or zoom OUT (fingers pulled apart). Circular motion can be used to rotate an
element on the screen. This function must be supported by either the Operating System
or the application.
