The mouse stays in one location with grippy feet and the trackball moves the cursor. There is no sensor for mouse movement. It does take a while to get used to.
The reason I chose it was that I didn't have enough desk space to move a mouse. I barely even had enough space to put the mouse. Now that I've moved house, I just like the novelty. It's not as accurate as a regular mouse.
I would love a mouse that could do both regular movement and trackball movement so I could have 4 axis inputs. Sadly, I haven't found any like that.
This is not true of all trackballs. Some can be more accurate than a mouse with the push of a button.
That may be technically true, but what's stopping someone from using the same button on a regular mouse?
A regular mouse can have a large amount of movement with your elbow and very fine control with your wrist. Your thumb on a trackball may have more range or precision than either, but not both combined.
My personal experience is that a trackball mouse is a little less accurate when trying to move a large distance precisely. Perhaps I just need more practice.
Do you have a button in your regular mouse that enables precision mode?
I don't personally have a regular mouse, but most "gamer" mice have a DPI button.
I have seen several pro gamers use the DPI button on their mouse to rapidly change their precision while playing. I suspect it would take more practice than I'm willing to put in, but they seem to use it to great effect.
Ok.
