One possible way to use this to replace the mouse that I am currently trying to get to work for myself is to use the mouse warp feature in conjunction with dwell clicking software. I have downloaded dwell clicker 2, and if I could only get the mouse warp to move the mouse where I look when I look at a different place (not when I move a separate mouse or click a key), then I think this product could potentially replace a mouse. I have also downloaded the tobii pceye go software, which they apparently offer for free, and believe that I might be able to get it to work with this eye tracker if I could simply get mouse warp to move the mouse where I look when I look. Unfortunately, it doesn’t look like that is an included feature, so I guess I’m going to be returning this eye tracker.
