Control room operators are an important component in various industries that require continuous operational monitoring and supervision. These professionals typically work in centralized command centers, monitoring and managing the performance of complex systems and infrastructure. That is why they need a well-designed control room operator design to ensure that their work runs smoothly and that they can perform at their best.

Human Factors-Based Control Room Operator Design

Control room operator design must be based on human factors to reduce human error during work, reduce fatigue factors, and consider operator safety factors while working in the control room. There are many other functions of applying human factors in control room operator design. Therefore, here are some examples that can be applied to human factors in control room operator design:
- Design that must accept input directly from operators.
- The layout of the control room operator’s workplace must take into account the interactions that must be carried out by each operator.
- The design must include the building structure, operator interactions, air ventilation design, room cooling, and soundproofing systems.
- Selection of the type of gear, computer, and monitor used (HD or 4k, Curved or Standard).
- A clear interface design, screen information that is not too dense (<50%), and a system design that takes into account the operator’s workload.
- Complete workplace facilities to accommodate the needs of operators who must work long hours.
- Conducting audits to ensure that everything is running smoothly and making improvements where necessary.
Ergonomic-Based Control Room Operator Design
After learning about human factors-based control room operator design, the next step is to learn about ergonomics-based control room operator design. The aim is to ensure that the control room operator design can accommodate operators from the 5th to 95th percentile. The following is an ergonomics-based control room operator design:
1. The height of tables, chairs, and other instruments.

Ensure that the dimensions used in selecting tables, chairs, monitors, and other work equipment are in accordance with human anthropometric dimensions to improve ergonomics and reduce operator fatigue while they work.
2. Placement of the main monitor and other monitors.
The placement of the main monitor at a workstation, assuming a 24-inch monitor as shown in the illustration above. The operator’s viewing angle can also be seen based on the colors in the illustration above to determine the operator’s future viewing with the monitor layout that will be used.
3. Placement of secondary monitors and maximum number of monitors at a single workstation.
Support monitors located on the wall can usually be placed as follows when designing a control room. The monitor size used in the illustration is a 24-inch monitor, with colors used to illustrate the operator’s unobstructed view of the monitor at their workstation. It should be noted that when sitting and standing, the position of the support monitor on the wall will be different due to the difference in height.
4. Interaction between operators and the distance between workstations in the control room layout design.

When creating the layout design for the control room operators, another thing that must be considered because it is equally important is the interaction layout of each operator and also the distance between work stations to ensure that operators can move freely, and the layout is also optimal because it takes into account the interaction of each operator.
