Touch sensor specialist Zytronic announced that it is taking its "rugged" Projected Capacitive Technology touchscreen solutions beyond the 2-dimensional domain by producing PCT sensors for digital signage displays that are curved along one axis.
Available in customized sizes from 19-inch to more than 46-inch diagonals, this large-format, curved surface 
product is available in single-, dual- or multitouch configuration. The screens are suitable for use with rear projection systems, the latest wave of curved LCDs or even OLED displays, the company said.
The radius of the curve can be specified by the customer, and the touchscreen can be made with a convex or concave configuration. Zytronic said it envisions that the convex designs will be attractive to designers of gaming equipment, where an interactive "spinning reel" movement can be simulated. The concave versions of the technology will facilitate the merging together of several angled screens to create a single, seamless user interface, the company said.
In both cases, the added dimension creates an organic feel, and allows industrial designers to push the boundaries of what is possible with touch interactivity, no matter the size or environment for deployment, according to Zytronic.
"This is the first time that ruggedized 10-point multi-touch, curved surface touchscreen operation has been feasible in the large-format factors that can be used in un-supervised or even outdoor locations, and it underlines the growing need for more sophisticated human-machine interaction in these sectors," said Ian Crosby, sales and marketing director for Zytronic. "This solution means that engineers are no longer restricted to single plane user interface deployments, but can create designs with enhanced ergonomics that reflect the growing trend already emerging in the portable consumer space for curved surface touch-enabled products such as the Samsung Nexus S and Nokia N9 smartphones."
