ErgoLib for Safer Library Computing

ErgoLib for Safer Library Computing



Working in a library can be hard, physical work.  And working with computers, mice, and monitors requires many of the same skills that successful athletes have. Get informed and start planning your own training program by checking out the following web sites and our list of quick, cheap tips.

 Cheap Tips for Safe Computing in the Library

  General

  • If it hurts, don't do it. Pay attention to how you're feeling, how you're sitting, and what hurts.
  • Keep moving - stretch, wiggle, get up!   
  • Tape up one of the many good stretch exercise sheets at your desk, next to your phone, and over the copier. Stretch while you're waiting, while you're on hold, listening to your voice mail, whatever. Set yourself a daily deadline; if you haven't done all your stretches by lunch, then you'll know what to do on your lunch hour.
  • Take real pictures of how you work. Get a video camera and have a colleague tape you working. Keep the tape and add to it yearly. The comparisons will be enlightening.

  Keyboarding and Mousing

  • Don't reach for or tightly grip your mouse. Position the mouse as close as possible to you. "Mouse shoulder" and "mouse arm" are debilitating conditions.
  • Keyboards should slope downward toward the back. Use pads of sticky notes to prop up the front of keyboards.
  • Use two hands to type combination keys (such things as Ctrl and F7), instead of one-hand stretching or clicking.
  • Better yet, stop all that clicking and learn the keyboard equivalents. There are several listings of keyboard shortcuts at the Bilbo Innovations, Inc. site. One of the authors, Susan Fulton, has updated her list and it's available at her site for voice recognition technology, Computing Out Loud.
  • Don't use a laptop in bed or on the kitchen table. Find a little table that's about 26" high.
  • Rest your wrists on a wrist rest only when you are NOT typing. Wrist rests are designed to support the heel of your hand, not for resting your wrists. Place wrist rests so that the top is level with the top of your keyboard's space bar.

  Eye care 

  • Don't work looking up at your monitor. Bifocal wearers need to be especially careful that their monitors are low enough to avoid neck strain. If necessary, pry off the stand at the base of your monitor to lower the height and/or move the CPU so it is not supporting the monitor.
  • Eyeglass wearers - go prepared to your next eye exam. Read up on vision requirements for computer users and inform your eye doctor of your work setup. Consider buying a special pair of computer glasses. Some health plans cover them. Or try dropping a pair of low-magnification "reader" glasses on top of your regular ones; they may look funny but the price is right.
  • Check your monitor for glare by holding a white piece of paper in front it. If you can see its reflection, you've got glare! Quick fix: tape a manilla file folder on the top or side of your monitor after moving it in and out to test for maximum light blocking.

  Posture

  • Don't stick your neck out -- literally. Your head weighs about 15 pounds. Keep it balanced over your neck and spare your neck and shoulders.                       
  • Find your chair's instruction book and adjust your chair. Learn how the controls work. If your chair does not adjust, work on getting a replacement. Replace your kitchen or dining room chair with a steno or other adjustable chair.      Try using pillows or books to adjust the height.    
  • Face your monitor and keyboard head-on. Make sure you're centered over the part of the keyboard you use the most. Don't sit centered over the number pad if you never use it.
  • Don't talk with the phone on your shoulder AND don't use a gadget to rest the phone on your shoulder. Get a headset, learn to type with one hand, or use a speaker phone.
  • Women - dump the purse and get a backpack or fanny pack. Also try sitting with your knees a foot or two apart - while your mother wouldn't like it, this position forces you into a better posture! That's why men sit this way
  • Men - don't sit on your billfold. Hip replacements aren't fun. (Put your billfold in your sock or a front pocket, so you don't leave it behind. And consider a fanny pack worn in front--lots of macho guys are wearing them these days!)  

Gizmos

  • Don't buy the first gizmo you see. Test them out!
  • Store bought items may not be the right height or comfort level for you. Make your own gizmos - Martha would!!!
    • For wrist rests -- try a rolled up hand towel or rolled bubble wrap secured with masking tape.
    • For foot rests -- try piling up telephone books or mail order catalogs so you'll know the exact height you need or whether you really need one at all.
    • For real handy types -- make little bags and fill them with brown rice for temporary or permanent backrests, footrests, wrist rests, back or travel pillows.
    • Need a soak -- use a plastic flower box or wallpapering box (shallow, long and narrow) to hold warm water for soaking forearms, wrists, and hands.
    • Need a cold press -- keep a few plastic bags of peas in the freezer at work and at home to use as ice packs on whatever hurts.

Library Case Study
Library patrons deserve good work stations, too. Below are before and after photographs of a library user sitting at a public CD-ROM work station.

In the before picture, the user must look up at the monitor and is sitting too low to reach the keyboard and the mouse.

After analysis, the major problem seemed to be the monitor shelf. The other problem was the chair, a desk chair several inches too low for use with a computer. The shelf was removed for the after picture. Replacing the chair will depend on our budget.

Before   After 
Notice her shoulder, neck and head position in each photo. 

As soon as she sat down, our model, Patricia Olhasso, commented (without prompting) that the second setup was much more comfortable. 

We used a volume of the LCSH for a booster seat. Don't worry - it's an old edition!
