    trackball

    Jim Weatherly

      I am having a lot of elbow pain from my cad work.

      I am using a track ball and have been since the turn of the century. I have tried them all, Pens and pads, balls and mice. Even the high end space balls.

      I have been designing one and may be doing a kickstarter introduction. BUT..................

      I don't think this is a million dollar idea but it has helped with the pain in my arm and it might help others.

      I have a design concept, sone sketches and hand built (functional) models but If I am going to take the next step It would be great to hear what the community has to say.

      My concept is simple.....really simple.

       

      But from what I have read here are some of the common concerns.

       

      The ball is too small.  Would anyone like a bigger ball. like tennis ball size?

      Its not easy to switch from left to right.

      no scroll wheel for rotating.

      not ergonomic enough.

      It's not easy to do a left button hold and roll the mouse.

       

      These are pretty general. Are there any specifics?
