Using Hope Industrial Touch Screens with Linux

Ubuntu Operating System

“How well do your touch screens work with Linux?” is a question we get very often. While the short answer is always “perfectly!” there is more than one way to support and align our touch screens with Linux operating systems, and which to choose often depends on the particular circumstances of a given application. In this article we will provide a high level overview of some of the more common methods for supporting Linux.

In future articles we will provide step-by-step technical descriptions of how to use these techniques, but in the meantime if you have any specific questions just let us know and we’ll do our best to help you out.

New Floor Stand Options Create Free-Standing Pedestal Workstations

Since their release nearly 15 years ago, our Industrial Monitor Pedestal Mounts have been one of our most popular display mounting options. Combined with an industrial touch screen, keyboard, and PC Enclosure, the pedestal base allows placement of a full HMI workstation anywhere on the factory floor.

Beginning this month we now offer two different optional floor stands for use with our Yoke and Pedestal mounts. Available with either locking casters with durable 3” wheels or with adjustable leveling feet, these floor stand kits can be used with any of our 4” x 4” pedestals, and can even be used to retrofit existing pedestals for free-standing use.

Tethered Stylus Options for Resistive Industrial Touch Screens

PDA Panache’s large (VTET), medium (MTET), and small (BTET) tethered styluses.

As we’ve talked about in other posts, our touch screen displays use resistive touch technology because of its many benefits to the industrial user. One of the most important of these is the fact that resistive sensors are pressure sensitive, which means that a gloved hand, a stylus, or most anything else can trigger a touch.

While most industrial HMI applications use interface screens designed to simply press with your finger (meaning, large buttons), we have some customers who require a stylus for increased accuracy. Over the years, we’ve recommended PDA Panache styluses to many users. We’ve found the company’s simple and sturdy designs well suited for many industrial environments.

We’ve tested many PDA Panache styluses but we generally recommend the VTET (large), MTET (medium), and BTET (small) models. (more…)

Rugged LED Backlights Now Used in Hope Monitors and Touch Screens

Model by model, we have been transitioning from traditional CCFL backlights over the past few years, and we are happy to announce that we are now using LED backlighting in all Hope Industrial Systems monitors and touch screens except for our 20″ models, which will be converted later this year.

Waking a Sleeping PC Using a Hope Industrial Touch Screen

With the right settings, a touch screen can wake up Windows

With the right settings, a touch screen can wake up Windows

In an industrial or manufacturing environment it is not uncommon to operate a computer with neither a keyboard or a mouse, using only a Hope Industrial touch screen to control the PC. For these situations we’ve discussed virtual keyboards to simplify data entry, and ways that a touch screen can better emulate a mouse.

A common question we get asked when users opt to run without a keyboard or a mouse is, “How do I wake up my computer from standby?” By default a PC that is in sleep or standby mode powers down the USB ports, which in effect disables the touch screen, preventing it from detecting a click and waking up the PC. Luckily with a modern properly-configured BIOS and operating system, full touch screen waking functionality is possible. (more…)

In-House Touch Screen Driver Testing and Certification

Elo Touch Screen Driver CD

Elo Touch Screen Driver CD

As discussed in other posts, we have always used Elo Accutouch resistive touch sensors and controllers in our touch screen models. Aside from the usual benefits of resistive touch sensors, the Elo Accutouch system offers high quality, extremely diverse driver support, and long term compatibility (DOS drivers from 20+ years ago still work with our current RS232 models).

However, before we supply drivers for customers’ use we always fully and rigorously re-test new drivers in our own lab, and make these drivers and our findings available on our website. Today’s post will discuss our reasons for doing this extra testing on a pre-certified driver. (more…)

Displays and Touch Screens Built to Last

8-year-old Industrial Universal Mount Monitor

Universal Mount Monitor with a particularly hard life

Hope Industrial Displays are built to handle abuse of many forms. Our displays are used in a wide variety of extremely tough environments where they see everything from daily steam cleanings to chemical exposure to the occasional run-in with a forklift.

But every once in awhile our repairs department sees a particularly tortured product come in for repair.

Consider the following: this Universal Mount 19″ Touch Screen has been in service for nearly 7 years inside an industrial equipment paint booth. During this time, the monitor has been subjected to constant heat, paint over-spray, and dousing with solvents to keep the worst of the paint off of the touch screen’s acrylic surface. (more…)

New “Touch Zones” Driver Feature Creates Non-Touchable Screen Areas

Touch Enabled Zone Configuration

Diagram 1 – an illustrated example of a Touch Zones configuration that would only allow touch within the confines of the HMI software

In most cases, industrial HMI software is designed to run in a full-screen mode, where all the user sees (and can therefore click on using a touch screen) is the HMI application itself. This prevents the user from interacting with the operating system directly and accidentally closing the HMI application, rebooting Windows, or worse. (more…)
