I wish there were more lefty options out there but there isn't much.
Indeed. I cannot say I have kept up, but I looked around a while back and, as far as I know, the Elecom M-XT4DR left-handed trackball is the
only thumb-driven trackball made today specifically designed for left-handed users.
Having said that, have you looked at any of the larger, old school ambidextrous trackballs that can be used with the fingers/palm of either hand? I am wondering if a larger, heavier trackball might help you as far as involuntary hand movements go.
(Of course, the old school trackballs do not tend to lend themselves well to precise movements, so you would be the best judge of whether or not this would be a good idea.)
I wish the larger models where available in Lefthanded versions however.
Me, too. However, considering how many years manufacturers have had to come up with new left-handed trackball offerings, the probability of another manufacturer getting into the game at this point is not likely to be high.
So, I am going to throw out an idea.
(NB: This idea is probably
far more trouble than it is worth and I am saying so up front. I only mention it because, a) you never know who is lurking on GH and, b) for all I know, someone reading this could have both the skills and the will to do it.
If that someone is
you, and you are looking specifically for a thumb-driven trackball designed for larger hands, it may be worth a go. Read on and decide for yourself.)
Last century, Logitech made a thumb-driven trackball called the Logitech Trackman:
As you can see, it was designed for right hands, but it was also designed for
large right hands. I know this because my own hands are in the large-ish range and, being ambidextrous, I used one of these for years.
(This next bit is where the "far more trouble than it is worth" aspect comes in.)
Someone well-versed in CAD software and small-scale manufacturing
might be able to pick up one of these, reverse the right-handed design, and make one (or have one made) for left hands.
Obviously, this is not something that could be done in an afternoon (to say the least), but considering what the offerings are in the way of left-handed trackballs, whoever does this might be able to sell a few (and, of course, they could always check the interest level for it on GH before they embark on the project).
The patent for this particular design ran out a few years ago (the first model of these came out in 1995), so anyone doing this may also be able to update the design a bit while they are at it.
(Now you see why I said it was probably more trouble that it was worth, don't you?)
