How do you select a touch screen technology?

The four most common touch screen technologies are: resistive, infrared, capacitive, and SAW
(surface acoustic wave). Resistive and capacitive touch screen technologies are the most popular
for industrial and small format applications. If the application requires that operators wear gloves
when using the touch screen, then resistive is preferred over capacitive. Generally, capacitive
technology offers better optical and touch performance, including multiple touch, but is more
expensive than its resistive counterpart.
