How to fix mouse cursor offset?

Question

Mouse

If you place the mouse exactly on the upper edge of the pad and start moving quickly left and right in a large amplitude, without changing the vertical position of the mouse, the cursor moves vertically, in my case up.

Can this be fixed?

Tried on different, including gaming mice, different mats and different computers, even on a Mac.



A more visual effect is obtained when the mouse moves in a circle of large radius.

Answer 1

I'm not sure you'll be happy with my answer. In order for the cursor to move exactly where I expect it to.

Danil Trubitsyn , If you put several protruding needles on the table, can you hit the fist exactly past them if you hit the table quickly, quickly? Especially without looking?
I doubt that your hand movements are more accurate than mouse movements.
If you want to do a real experiment, don't move your hand, but build a mechanical device that will definitely move with precise positioning.
Your hand moves ambiguously. In addition to moving up-down-left-right, it also performs a rotation imperceptible to the eye (especially at a large amplitude), and an up-down movement, plus a banal vibration. This all affects how the mouse detects movement.
Therefore, the ideal movement in a device manipulated by a person is impossible.

Answer 2

Alas, this is a matter of physical measurements, which are not accurate. Depending on the task (the task that you are actually solving, you didn’t bother to describe, which is bad ), you can either improve accuracy by replacing the mouse with another positioning device, or filter the input, for example, with a Kalman filter, which also imposes some restrictions.

Answer 3

I can offer a 99.99% working option. (why not 100 - because I didn't check it :-)
We must take not an optical, but a mechanical mouse. With a ball which. There, if you really need to fix one direction, you can figure out how to fix it exactly. For example, make a button that will turn on the corresponding sensor. If you press - it moves horizontally, if you press another - it moves vertically, if you don't press anything - it doesn't move anywhere. You can glue them right on the sides of the mouse, under the thumb and little finger. It will be easy to get used to. One problem - such mice have poor accuracy, and reliability is below the plinth. And you need to clean often.
