Correct angle for keyboard

Correct angle for keyboard
Osiris wrote
Archie wrote Is there a generally-accepted best angle for the slope of a regular keyboard? One web page says this: ------------------ BEGIN QUOTE ----------------- "angle of the keyboard relative to the angle of the wrist. Most keyboards slope upwards from front to back, and this means that users bend their hands upwards when they are typing on the keyboard. This posture is called wrist extension, and we know that it is a source of injury risk for the wrist. Once the hand is extended beyond about a 15° upward angle, there is a very significant increase in the compression on the median nerve and other structures inside the wrist. So it is extremely important to type with the hands as flat as possible. From http://ergo.human.cornell.edu/AHTutorials/ckd.htm ------------------ END QUOTE -------------------- Which I interpret as being zero to 15 degrees. But my Compaq keyboard permits either: (1) flat or maybe 5 degrees (2) about 30 to 35 degrees. Undoubtedly there is a generally accepted etc. Nope, if there was, the tilt wouldnt be adjustable. ISO has standards, Pity there isnt one for the keyboard angle. and I'd say ISO is the nearest you can get to "generally accepted". Nope. In spades when ISO is silent on the keyboard tilt. However: the most imporantt thing is to educate people to start FEELING. Is that anything like getting all touchy feely ? Feel how you sit, does your back start to hurt, pain in the legs maybe ? Do your arms feel "folded" too strongly... Que ? How do the wrists feel after 15 mins of typing ? You wont get any effect after 15 mins. many people just keep plowing on during a work day, Havent noticed too many plows with keyboards. racing the rat race. Not a great idea to try that with a plow either. Then: writsts are different from person to person. So why exactly 5 or 6 degrees tilt ? A general guideline... no more. In the early 80's we had IBM keyboards of maybe 10 cm THICK on the table. Which had adjustable tilt too. Funny that. I was not hurt, because my work had enough variation: no full day of typing, but programming meant: type a line, think, type a line, think... Enough rest periods. I can imagine the wrist angle makes a difference. But that does not immediadtely translate in keyboard tilt. Subtract the angle of the lower arm first. Its generally agree that those should be horizontal, tho without much rigorous science behind that. I'd say, the first thing to do to avoid injury is to define the persons function description. And tune in to the feeling. No thanks, not into touchy feely, thats for limp wristed wimps. Nowadays, typing requires so much less forcce than in the era of the Remmington typewriters. The effect is, that people keep going on, thinking that the physical load is less. But maybe load x time is the same as before... And the repetition is a lot higher.. Nope, not with decent editors it isnt. BTW: forget about Rod Speed: he only has opinions, no arguments. You in spades in that **** above, child. He even thinks the VW beetle is a great car... Never ever said anything like that, child. go figure. Nothing to learn there. From your post, sure, you did manage to get something right. |
