New – Encoder Combines LCD Touch Screen within Rotary Switch

Grayhill Touch Encoder features innovative user interface that supports custom layouts and multiple language options

Human Machine Interface (HMI) specialist EAO has introduced an innovative Touch Encoder that integrates a touch-screen LCD display with a multi-function rotary switch and pushbuttons in a single product. The new innovation from Grayhill Inc streamlines Human Machine Interfaces (HMIs) used in medical electronics, audio/visual and specialist vehicle control applications. Instead of tweaking multiple knobs the new device enables users to fine-tune their equipment control while keeping their hands in a single position.

The multiple configuration options provided by the new Touch Encoder are configured using an intuitive iPad development kit app that provides access to tap, swipe, and rotation gestures and makes it easy to support custom layouts and multiple language options. Rugged, sealed and impact resistant, the new device will also be welcomed by engineers developing emerging control applications where intuitive control is paramount.

According to Robert Davies, Marketing Manager with EAO UK, replacing multiple buttons saves on unit price and tooling costs, while the simplified interface makes user training easier: “Grayhill’s intuitive tablet development app enables the user to personalise multi-touch gestures, generate images, customise the display, and even trigger the logic on the Touch Encoder – all without the help of a software engineer,” Davies said.
