Some of the first American digital computing machines were developed in 1945 due to the need for quick and reliable military computations for projectile trajectories. The Electronic Numerical Integrator and Calculator (ENIAC), developed by John Mauchly and J. Presper Eckert at the University of Pennsylvania, was a significant achievement, as Grace Schultz stated in her article for the Encyclopedia of Greater Philadelphia, “the ENIAC was not limited to one type of calculation and could solve many different types of problems. As the first automatic electronic digital computing machine, the ENIAC marked the dawn of the Information Age”.

Building on this foundation, Eckert and Mauchly later went on to develop the UNIVAC, with funding from the Census Bureau made possible by the constant inertia and interest these early computational machines had aroused in governmental and public settings. The UNIVAC became the first commercially available electronic computer, used by both businesses and governments.

The advancements of these computers implied a broader spectrum of monitoring, calculating, and controlling technologies that were made available for process control operations to take advantage of, implying a slow but consistent migration from gauges, dials, levers, and hand wheels into electronically controlled buttons and switches.

These companies weren’t the first to create personal computers, but they were instrumental in developing smaller, more affordable digital computers that brought immense capabilities to various industries.

This shift towards miniaturized computers had a profound impact on control room design.

No longer confined to vast rooms dedicated solely to housing hulking mainframes, the core computing components could now be integrated directly within the consoles themselves. This wasn’t just a space-saving measure; it opened up a world of possibilities for process control operations tailored to specific needs.

This newfound flexibility empowered operators to handle a wider range of monitoring and control tasks simultaneously, fostering a more efficient and streamlined workflow. The control room itself could be transformed from a sterile, technology-dominated environment into a strategically designed workspace that prioritized operator comfort, information accessibility, and ultimately, enhanced process control.

The Introduction of CRT Monitors

The appeal for ergonomics in the workplace gained traction as machinery and equipment evolved, demanding changes in operator roles and tasks.

Organizations began to understand that even the most advanced equipment couldn’t prevent fatigue-induced mistakes that could halt entire processes and incur significant costs.

This realization highlighted the need to prioritize operator comfort and empower them to perform at their peak throughout their shifts. As a result, ergonomic principles for design emerged. While the International Organization for Standardization (ISO) itself was founded in 1947, its ergonomics standards committee (ISO/TC 159) wasn’t established until 1961.

This committee has since developed numerous ergonomic standards covering various aspects of workplace design, including the ISO 11064 series specifically for control room design. Developed during the 1990s, these standards aimed to provide a baseline for dimensions, viewing angles, operator position, and more. By adopting these principles, facilities could create optimized environments that boost operator performance during stressful scenarios and long shifts.

Ergonomic standards, such as ISO 11064, became integral to the design of control room furniture. These standards prioritized user-centered design, focusing on optimizing operator comfort and efficiency.

The shift towards ergonomic standards brought a heavy emphasis on operator ergonomics within control room console design. Various factors within control room operations were considered to enhance operator performance and focus while mitigating fatigue.

Features to optimize focus and comfort

Sit stand functionality

In the 1990s, the introduction of sit-stand functionality revolutionized control room furniture design. Electronically controlled actuators enabled precise parallel leg movements, allowing operators to adjust the height of their work surfaces.

However, this trend didn’t gain traction in North America until the late 2000s when James A. Levine, MD, PhD. a professor of medicine at the Mayo Clinic, exposed the dangers of prolonged sitting and its harsh impact on the human body.

Control room lighting

As control room design evolved, the importance of optimized lighting solutions became increasingly apparent. This is reflected in the ISO 11064-6 standard, environmental requirements for a control room, which among other environmental factors, emphasizes the need for lighting that caters to the specific visual demands of control room tasks.

Remember how the rise of ergonomic principles led to the creation of specialized workstations tailored to operator needs? Localized lighting solutions are an extension of this ergonomic philosophy. With multiple operators working in close proximity on various tasks, traditional one-size-fits-all lighting wouldn’t suffice. The potential for glare and disruptions to other operators needed to be addressed.

Enter the Three Lighting Categories

  1. Ambient lighting
    Provides general illumination for the control room, ensuring a comfortable overall light level.
  2. Task lighting
    Focused illumination directed at specific workstations, or sections of the console, allowing operators to adjust the brightness to suit their individual needs and the task at hand. This eliminates the issue of glare on neighboring consoles.
  3. Therapeutic lighting
