Touch/virtual button all-in-one design concept for rugged applications

Zytronic has extended its capability and can now work closely with clients to design and produce projected capacitive user interfaces that join a 'traditional' dynamic touch area with surrounding capacitive keys.


Named ZyBrid VK, and based upon the company's multi-touch capable, projected capacitive technology (MPCT), this latest advancement opens up new opportunities to enhance and improve the design of HID for an extensive range of applications that prove testing to conventional approaches.


The company's solution enables a touch display of an appropriately small size to be paired with non-mechanical printed and fixed keys in the same glass surface. This method has the further benefit of forming a seamless, totally sealable user interface, with no holes or gaps to trap dirt or allow liquid ingress.


The patented projected capacitive touch technology can identify multiple simultaneous fingers, conductive styli and even dirty or gloved hands, through glass thicknesses of 10mm or more. By doing so, it disregards raindrops, leaves, dirt, ice and other debris that can ‘fool’ different touch solutions. As a result, the solution is ideal to use both indoors and outdoors.






“Operation of the ZyBrid VK keyboard function is achieved before loading of the native Windows desktop,” explains Dr. Andrew Morrison, technical director at Zytronic. “The ZyBrid VK boots as a native HID keyboard, HID touchpad and HID touchscreen. This allows keyboard functionality via the sensor at the boot level, and once the Operating System desktop has fully loaded, the functionality of the three functional areas is available. A significant benefit for integrators is that no drivers are required since it enumerates within multi-touch capable versions of Windows or Linux as native HID devices, and therefore operation is available straight away.”
