I have noticed the elbow 90 degree advice a lot.
I am just confused how the elbow relates to the pinky.
The mouse thing is interesting. is there a software that I ca use to switch my right hand designed mouse to my left hand.
PS: wonderful advice !
Like, swap right button with left? There is an option for that in "accessibility settings" of most OSs. Left-handed people use it sometimes.
BTW, two possible sources of mouse issues I know:
1. Sharp angle between palm and forearm, happens when the mouse is too low and too close to the body. Put it elsewhere.
2. Palm forced to lie horizontally, while the natural position would be angled (lay your hand comfortably on the desk and see that the palm isn't flat at all). This is solved by putting mouse on angled surface or getting mouse/trackball with angled top. See Microsoft Trackball Optical (not sold anymore) for example of what I mean.
Ergonomics are extremely important for our profession (obviously). Examine how your elbows are situated in relation to the keyboard. If you're sitting at a desk, be sure to have a keyboard tray underneath the desk so that when your elbows are at a 90-degree angle, the keyboard is underneath your fingers and your wrists are straight and not bent. If you know anyone who plays piano regularly, ask them to show you their positions and posture, and try to replicate that at your desk. HTH
