I sometimes develop muscle strain when using a mouse for extended periods (ie all day).
My elbow also suffers from the effects of being pressed to a desktop as it acts as a fulcrum for the mouse-wielding hand.
Today’s invention is therefore a mouse which sits under one’s elbow and provides a comfortable pad which also has a low friction undersurface, so that the elbow can move freely wherever it needs to.
This would have a flat arm extending across the desk with a jointed front section to which one’s favourite mouse could be clipped.
This would allow full normal wrist movement but with added support.
