Hello, good morning everybody and many thanks to attend this webinar regarding ergonomic factors for successful control room design.
I’m Rafael Serrano, Technical Consultant for Control Room at Adder Technology and on several slides we are going to cover several aspects associated to the operator ergonomics and how our technology will help you to improve it. We hope you consider it interesting and useful to be applied in your next projects.
Please don’t hesitate to ask any questions you may have, it will be our pleasure to help you more on it so let’s start.
When we talk about Ergonomics in the CR design we should think that one of the main goals is to Minimize the risk of human errors and minimize the operator response time
To achieve this goal we consider different ergonomic paradigm from the physical aspect to the Mental aspect. Concretely we consider Cognitive Ergonomics, Environment Ergonomics and Workplace Ergonomics. All of that involving operators in the CR design and putting the Human Factors and Operators in the middle of the analysis for a User Centered Design.
The UCD Will help us to understand much better the operator needs detecting improvement points for a better and secure operator performance.
On the next slides will consider the different Ergonomic paradigms having a UCD perspective to achieve that “is the work place who must adapt to the user and not the other way around”
Let’s start from the mental part regulated by the Cognitive Ergonomics. This part is really complex where there are involve processes, perception, memory, reasoning and many other intangible subjects really difficult to evaluate. It’s out of our scope to go deeply on it but we’d like to give three points that can be easily considered.
One of the points is that the Operators Role in a CR is to take decisions according to the data they are managing. No matter what’s the CR application, from Industrial to Mission Critical.
If we take a look on this Endsley graph regarding the State of the systems. The Situation Awareness to take Decisions is based on Perception; Understanding and Projection so the systems design and the AV part for the CR is crucial for it. Global view of the complete picture in the VideoWall and local view in the operator workplace are key points. As much better information they have much better decisions they will take.
Another point is that Data handling techonolgies and a right Screens layout in the CR will shift the human cognitive energy and consequently Will help the operator to improve eficiency and reduce human errors.
And the third point is that as decisions are made based on data and the amount of data to manage is increasing, we need to consider seriously a correct Screens layout, Data handling technology systems and ergonomic systems design to avoid “Tunnel Vision” issues.
If we take a look for a work place we can quickly identify all the cognitive points and how we can help to improve it with our technology
Going now to the physical part let’s start with the Workplace Ergonomics and trends that are aligned also to accomplish the Cognitive Ergonomics we saw before so there is a clear interrelation amount the different Ergonomic paradigm to align one to another.
As you can see on the pictures the Trends are: ---------------------------
Let us see different views in more detail.
On this view we can see how important is to give a large working area to the operator. 775mm as a standard that is around 82% of the table Surface is allocated as working area.
We also can see that thanks of the use of KVM technology, no computer zone is needed and the free area underneath the table surface is 1050mm so the operator can have more freedom and comfort. This also help to the workplace to be able to combine sit-down and stand-up working positions that also is ergonomically needed.
On the Screen part you should consider screen positions to quickly identify the critical information and combine local/process view in the workplace and Global View in the VideoWall respecting the Standard visual line 0º for local view and the 25º as maximum eye rotation for the VideoWall having no interferences in between from other operator workplaces or architectural elements.
The use of KVM matrix systems will help to locate the right information on the right place to identify quickly the critical process and help the operator to adapt the workplace to their own use.
Finally on this third view we can clearly see how by having a single Keyboard and Mouse to work with different systems across different screens with automatic KVM switching systems improve the Working Area and simplify the interaction operator-machines. Also improve the ergonomic aspects of the technical furniture taking advantage of its ergonomics benefits. Sometimes customers invest on technical furniture and didn’t consider any KVM integration loosing 70% of the ergonomic benefits provided by the tech. furniture.
If we take a look for a work place we can quickly identify all the workplace points and how we can help to improve it with our technology

In conclusion the integration of our technology can help to improve the ergonomics in the Control Room and is really important to consider it from the beginning on the Design part and my recommendations are: (next slide)
