Ergonomics Design and Evaluation

Updated on January 21, 2010

The ergonomic design and evaluation area is involved in the design and evaluation of equipment, systems, and work space at workplace, their contribution used as a basic attitude and anthropometric data obtained, biomechanical assessments, sociological characteristics and habits of the population that design targets. When designing or evaluating a workspace, it is important that a person may need to use more than one workstation to perform their activity, likewise, more than one person can use the same workspace in different periods of time, so it is necessary to take into account differences among users in terms of size, distance, range, strength, and visual capacity, so that most users can perform their job safely and efficiently. In considering the range and capabilities of most users in the design of workplace, safety equipment at work and work tools and devices play an important role to help reduce unnecessary effort and stress on workers, increasing safety, efficiency, and worker’s productivity.

As you know, man on its own is the most flexible system and can modify and change its styles and habits of working according to the conditions and circumstances that means if a worker is provided with poor working conditions and poor work equipments, he/she will perform that work but it will require much more time, attention, and focus thus reducing the worker’s efficiency and productivity and may develop problems such as repetitive strain injuries like deQuervain’s tenosynovitis and carpal tunnel syndrome or repetitive micro traumas or some other problems after a period of time that develop due to those deficiencies. In general, we can say that the operator's or worker’s performance is better when he/she is freed from distracting elements competing for attention with the main task since when is required to allocate part of mental or physical effort to handle the environmental distractors, there is less energy available for productive work.

  • Ergonomic Helicopter cockpit design and physical workload evaluation using the anthropometric data of Korean helicopter pilots and the US army personnel.
  • This cockpit layout design was evaluated from the aspects of physical workload in a digital environment.
  • At the end, a physical prototype was used to validate the helicopter cockpit design by helicopter pilots.

Special Needs Ergonomics

Special Needs Ergonomics is the area of ergonomics that focuses on specific needs to the design and development of equipment for people with physical disabilities and serves mostly to the child population and schools for the design of micro-autonomous devices that make life of people with such disabilities much more comfortable and easy. It is understood that people with special needs cannot be treated as "general" because the characteristics and conditions for each of them and us are different so it is required to build separate designs for every unique person and a specific user.

Preventive Ergonomics

Preventive Ergonomics is the area of ergonomics that works closely with the disciplines responsible for safety and hygiene in work areas. Among its main activities is the study and analysis of security conditions, health, and comfort of work. Specialists in the area of preventive ergonomics also collaborate with the other specialties of ergonomics in the analysis of tasks, such as the biomechanics and physiology for the assessment of effort and muscular fatigue, determination of working time, and rest and so on.

      Thank you so much Veronica for your understanding. Being an ergonomist is a good thing.

      Good Information. Although I was aware of its existence, I think that it is so admirable that those working in this field have made the life of those who may be physically limited a little easier.
