WHAT IS ERGONOMIC DESIGN? The word ergonomic means human engineering. Ergonomic design is said to be human-centered design focusing on usability. It seeks to ensure that human restrictions and capabilities are met and supported by design options.
In an ergonomic environment, equipment and tasks will be aligned. Ergonomic design stage before the problem is determined and the appropriate testsaredone to solve the problem.
The experiment design emerges afterwards.Mass production of products do not take into account that humans come in various shapes and sizes. The proportions of a chair that work well to support a six foot tall body frame can add stress and challenges to a smaller sized person. Mass production can make the most commonplace products difficult to use.
Considerations like the size and shape of tools and how they fit into the hand that will use them are important to ergonomic design. A can opener requiring little effort from the strong hands of a twenty year old male might present significant challenges for the weaker hands of a seventy year old female.
A thorough understanding of the specific tasks an object is intended for is central to achieving the ergonomic design goal of aiding the human form in executing them. Quality ergonomics is thought to reduce the risk of injury and errors by ensuring that technology and humanity fit and are working together.
Greater accuracy and more efficient performance will be achieved by meeting human needs with technology. Quality of life will also be improved.
Poor lighting and glare from computer screens in work spaces can detract from performance by adding difficulty. Ergonomically incorrect lighting can result in neck or eye strain and shorten the time a worker is able to perform a task in this environment.
Ergonomically correct lighting can make the same task easier by improving a workers ability to see, reducing neck and eye stress, and allowing performance of the task longer and more efficiently.
The need for ergonomic design is thought to have originated during World War II, when it became apparent that military systems could be more effective if they took into account the environmental requirements of the soldiers operating them.
After incorporating ergonomic changes in some military systems, efficiency and effectiveness as well as safety were improved.

Ergonmics is a branch of science drawing from physiology, engineering and psychology studies. It seeks to harmonize the functionality of tasks with the human requirements of those performing them.
Ergonomic design focuses on the compatibility of objects and environments with the humans using them. The principals of ergonomic design can be applied to everyday objects, and work spaces.
