My family is hoping to set up a computer for my grandmother so she can keep in touch with people. One issue that I haven't found an answer for yet is that she and my mom both have something called Essential Tremor, which is a genetic tendency to shake, similar to what you might see in someone with Parkinson's. This would make it extremely frustrating to use a mouse, as it would jump all over the screen and click on other things than what was intended. While one could just slow down the mouse response, that would only limit how far the cursor jumped, not how much, and would make it irritating in different ways. There is apparently a hardware device that can be placed inline between the mouse and the computer to moderate the signal into something smoother, but it cost a few hundred dollars, so it would be nice if there was another way. What I am wondering then is whether there is a software method for adjusting the sensitivity of mouse input and correcting for jitter from hand tremors, and if so, how would I go about setting it up?
