Technical Writing
Written for the people who actually specify this hardware. How the technologies work, where each one fits, and the trade-offs that don't show up on a datasheet.
Projected capacitive is the default choice for modern HMIs — until it isn't. How PCAP sensing actually works, why controller tuning matters more than the sensor itself, and what separates a field-ready module from a repackaged consumer part.
Read the article →Capacitive gets the attention, but resistive still wins in specific cases — thick gloves, styli, heavy contamination, and cost-driven designs. Where the line actually falls.
Read more →You don't always have to choose between glove operation and pinch-zoom. How Resistive Multi-Touch Systems bridge the gap for rugged HMIs that need a modern interaction model.
Read more →Removing the air gap does four things at once: raises ambient contrast, improves impact resistance, stops internal condensation, and reduces parallax. Why it's rarely optional outdoors.
