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

Touch Enabled Zone Configuration

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…)

Using a Raspberry Pi with a Hope Industrial Systems Touch Screen Part II: Touch Screen Setup

Hope Industrial UM22 Touchscreen and Keyboard with Raspberry Pi internally integrated

In our last post we introduced our Raspberry Pi proof-of-concept project and outlined the physical components and setup required for using the Raspberry Pi as an industrial touch screen PC in a harsh environment. Please see our previous post for important information to consider before integrating a Raspberry Pi with our industrial touch screens.

In this post, we will show how easy it is to set up the Raspbian Operating System to work with a Hope Industrial touch screen without adding any third-party drivers. This how-to assumes a basic understanding of Linux command line use and text file editing. Feel free to contact us with any questions. (more…)

Using a Raspberry Pi with a Hope Industrial Touch Screen and Keyboard

The Raspberry Pi is a small single-board computer originally created by the Raspberry Pi Foundation as an affordable tool for teaching computer science. Due to its low cost, ease of use, and broad community support, the Raspberry Pi is now being used in a variety of diverse settings with users installing them in everything from home automation systems to autonomous aircraft.

Most of our customers connect our touch screens and displays to full industrial or commercial PCs and thin clients for industrial HMI and SCADA applications. But with the popularity of the Raspberry Pi, we have had multiple customers ask about compatibility of our screens with the popular single-board device. (more…)

Product Spotlight: Industrial Monitor Screen Protectors

Our industrial touch screens use resistive touch sensors (discussed here), which are well suited for harsh industrial environments. The outer layer of these sensors is made of a polyester sheet that is coated with an acrylic “hard-coat” film for added scratch prevention. As a result, our touch screen sensors have a hard-wearing surface that is suitable for most environments. (more…)

More Advanced Options for Industrial Touch Screens

Depending on the environment, there are different requirements for user interfaces and how people need to interact. Recognizing this, Elo added a few features to their drivers that provide some advanced functionality to enhance usability for very specific purposes.

Click on Touch

Some interfaces require that the end user only perform a single momentary tap or click with no desire to drag anything or no need to “click and hold” for any amount of time. A good example would be a motor toggle or a machine that requires fine tune adjustments by just one tap or click at a time. This feature is particularly effective if your user interface requires only a single instant click.

A Simple Industrial Touch Screen Driver for Ubuntu Linux

Ubuntu Linux Desktop

Ubuntu Linux Desktop

More and more often, our industrial touch screen customers are taking advantage of the open source Linux operating system, Ubuntu. Ubuntu has evolved into a versatile, easy-to-configure environment with a large community following and massive support from the company Canonical. We have seen a steady increase in calls from customers leveraging Linux in industrial environments, and in recent years Ubuntu has been leading the charge. In addition to the standard Elo-provided Linux driver, Ubuntu users now have a very simple touch screen driver solution that requires no new software. (more…)

Advanced Mouse Functions with an Industrial Touch Screen

In most typical applications, Hope Industrial touch screens are used to be part of a PC-based HMI configuration, performing some type of PC-based control of an industrial process. The programs that generate these automation interfaces are generally designed with a very simple interface: large on-screen buttons allow simple interaction to a busy, often gloved worker. Generally, the user does not interface with the underlying PC operating system. To operate this type of application, the touch screen does no more than simply pass single “clicks” to the computer, which responds as if a mouse button was clicked. (more…)

Enhanced Calibration for Industrial Touch Screens

Elo 25 Point Enhanced Calibration for Touch Screens

As a rule of thumb, we recommend calibrating your industrial touch screen if the cursor is more than 0.25″ from the exact center of the point of touch. Doing so will increase the accuracy of the touch response and can make it easier to touch objects with pinpoint precision.

While the level of accuracy provided by the default alignment routine is sufficient for the vast majority of applications, an even greater degree of precision can be achieved by using the enhanced calibration routine provided with some versions of our Windows touch screen driver. (more…)

Single-Touch Gestures for Industrial Touch Screen Applications

Due to their advantages for the industrial market, Hope Industrial Systems’ products have always used resistive touch screen sensors from Elo TouchSystems , which support single-touch recognition. While many of the advanced touch features we have come to love in our smart phones require a “multi-touch” technology (like pinch-to-zoom), the recent release of a new series of drivers from Elo now allows some of these features to work with any Hope Industrial Touch Screen.

Elo provides the driver in the support section of their website under the “Windows 7 Multitouch” section. Although the listed notes for the driver mention that an IntelliTouch monitor is required, we have done extensive testing and found it to be compatible with our AccuTouch-enabled (resistive) Elo touch screens.

Replacing Another Panel Mount Monitor with a Hope Industrial Monitor

There are several factors to consider when an existing panel mount monitor has failed and it is out of warranty. Most users opt to replace the display since many manufacturers will charge more and take longer to repair the monitor when compared to buying new. Much of the reason is due to the declining cost of LCD’s over the past several years. Therefore, it is wise to consider all the factors in total cost of ownership when selecting a monitor for a new project.

Here are the questions to ask that affect total cost of ownership:
