Ergonomics

Recently we did a small activity in class investigating the ergonomics of working on a computer. First of all, according to Jonathan Bailin, Ph.D, ergonomics is "the science of adjusting your work environment to fit your body and make it more comfortable". Most of the stuff we learned was relatively simple, straightforward stuff like how close to sit to your computer screen(about 25in away), the best and most comfortable position for your feet and arms while typing for extended periods of time. However, i was a little surprised to hear that extras like wrist rests for working with a keyboard or mouse are not truly necessary and can, in some cases be more harmful or tedious. The whole lesson made me much more conscious of how i sit and type and how long i sit at a computer without resting my eyes. It was, over all, very interesting.
