Page 61 New Touch Encoder Technology Is More Intuitive Continued from previous page A simplified interface also helps with train-
ing, since workers do not have to navigate through a complex user interface on a cumbersome panel to operate a piece of equipment. Anyone who can use a smartphone can walk up to a machine and quick- ly become proficient with this intuitive device. For the digital audio-visual market, touch
encoders are an excellent choice for those perform- ing audio and video mixing. Instead of moving between multiple switches and pushbuttons to tweak functions, sound and video engineers can keep their hands in one spot and perform all the functions with one control. For the vast majority of applications, design-
ers use a universal serial bus (USB) or CAN bus protocol for communicating data between the touch encoder and the host processor. For exam- ple, once a developer writes an app and downloads it onto the device, users can plug the Grayhill touch encoder into a computer, and it will instantly recognize the device. In off- highway, industrial and some med- ical devices (interventional devices, X-ray or CT scanners), a CANBus protocol is used to conveniently com- municate with multiple devices on the same bus interface.
Under the Hood New touch encoder technology,
like that from Grayhill, is built to sur- vive harsh environments without sac- rificing style or functionality. The touch encoder uses a non-contact Hall effect sensor to provide coded output, determining the position based on

technology capable of placing so much functionali- ty in one control, ease of application development is vital. Grayhill’s touch encoders use an extreme-
ly simple, tablet-based development kit that allows anyone to create a custom interface. Industrial designers can personalize multi-
touch gestures, generate images, customize the display, and trigger the logic themselves, without needing a software engineer to configure the device. Designers communicate to the software
development kit (SDK) wirelessly, so no hard- wiring is required. After receiving the develop- ment kit, designers simply unpack it and immedi- ately get an overview of how to write a program using the application on the tablet. Within half an hour, users can be writing programs and down- loading software, making the entire development process extremely easy. By combining the functionality of a rotary

feedback from the sensor. Designed with a sealed, rugged construction, it is also impact-resistant and will sur- vive environments in which other user interface devices would likely fail.
The touch encoder has been
engineered to have excellent haptics — providing consistent and crisp feed- back to the user, and ultimately showcasing the high quality of the device or end product. The switch detent is repeatable and stable over its life in environments where it can be subjected to wide temperature ranges, electrical noise, vibration, and shock. The touch encoder has a clear,
high-resolution color display. It sup- ports no-look operation, multiple con- figuration options, and can incorporate tap, swipe, and rotation gestures. Using the touch encoder makes it much easier and less costly to support multiple languages. Those transition- ing from older designs can use the touch encoder to get an up-to-date design with much more information than what is available on a mono- chrome or low-resolution color display.
