But when your forearm starts achin' it's time to be makin' ... a change.
If you build it, they will come ...
Here is the natural position of your hand on the desk in front of your body.
This is the way the nuns taught me to write with an ink pen. They would sneak around the room and if they couldn't yank the pen out of your fingers effortlessly ... you got the ruler across the knuckles. You see, this is the way men wrote for hundreds of years with a quill pen. They were the first to experience carpal tunnel syndrome. Imagine Victor Hugo writing Les Miserables by hand with a quill pen (the only available instrument at that time). Think they would have discovered the most comfortable way to write? Dam straight. So that's how the nuns taught us.
So here's my design for a mouse. It's just the quill pen revisited in the electronic age.
More pics and explanations.
The outlined area is the middle finger rest. It's slightly above the table as would be the case while using a pen. When you grab the thing, the thumb, index finger and middle finger form that little triangle from which the "sail" sticks up through.
The sail part isn't really necessary ergonomically speaking but I thought that it wouldn't get in the way and would make a nice place to put my "cut, copy, paste" (X,C,V) buttons which I have always lusted after. You can get to them real easy with the thumb. Very convenient for heavy users.
Below, you can see a dark brown spot to put the thumb on. It's not a button. Rather, it's a sensor like the ones you use to touch-turn-on a lamp. What's it for? Well, if your thumb moves off this spot, the cursor won't move. So if you want to reposition the mouse on the desk, you lift your thumb a little and drag the mouse back where you want it. As it is now, if you want to perform this function, you must physically pick up the mouse and put it down where you want while the cursor remains stationary.
The "B" button is the back button for the thumb. On the other side is the left mouse button used by the index finger and the right (context menu) button is just above it. Just where you'd expect them to be and most convenient. "F" is the forward button infrequently used by the index finger.
Note: All buttons are programmable. I'm just giving the default settings here. I like to give the user the most latitude possible because only he knows exactly what he needs.
I also installed a scroll wheel (it's a washer I pushed into the Play-Doh which was applied to a wire hangar frame). I've since decided that the scroll wheel is obsolete and shouldn't be used anymore. In it's place we need a simple button which puts up that scrolling arrow thingy (Microsoft's invention). You then just move the mouse and the page auto-scrolls. However, as is always the case, the auto-scroll function isn't quite right.
What I want is a "percentage scroll per unit length of travel". This means that when the scroll arrow thingy comes up, you move the cursor some set distance (determined by you) and the page scrolls to that position in the page. Thus, if you say 2 inches of cursor movement equals 100% of the page, then 1 inch of movement will be 50% of the page and so on. No auto-scroll. I hate auto-scroll.
I know this will work so where is it?
I grant that this will not replace the standard mouse. The standard mouse is just too easy to use ... but ... when your wrist and forearm start hurtin' and you know your career is in danger ... you need a viable option. This is it. The professional computer user should have one of these from the start so as to avoid turning the forearm to the stressed state demanded by the standard mouse. That stressed state, continuously experienced, will eventually destroy anybody's arm in the long run.
Lastly, this is, of course, meant to be an optical, cordless model.
