Feature Request: mouse speed adjustment

[danrobi11]

Would be nice to have mouse speed adjustment. Doing that on Linux is not that straightforward. See this

Thanks!

[sezanzeb]

that might actually be possible yes. Busy with a few other open tasks here right now though, so it will take some time until this feature potentially arrives (If I do it)

Handling mouse movement events is also relevant for https://github.com/sezanzeb/key-mapper/issues/79

It would be perfect if this tool could also handle different acceleration profiles.

Just a small note regarding implementation in a far future:

Adding this became easier with the architecture changes of 1.2.0.

There would have to be a new consumer object for EV_REL events. EV_REL event values are integer values, that means the consumer cannot inject 1.1 to make the mouse move 10% faster.

• Option 1: Increasing the injection speed to 110% would increase the mouse speed. I don't know if there is a limit on how fast EV_REL events may be injected, if so, then at 200% speed it could multiply all values by 2 and inject them at the original speed again. This way the frequency of injected EV_REL event would not exceed 200%.
• Option 2: After injecting a value of 1 9 times, inject one more with the value of 2. On average the mouse pointer would move 10% faster. This is how the EV_REL events are injected when using gamepads.

Reference implementation that does something similar for gamepads: https://github.com/sezanzeb/key-mapper/blob/main/keymapper/injection/consumers/joystick_to_mouse.py

(besides having to add configuration elements to the gui)

There has been a feature request asking for an adjustment on the fly via a key press: https://github.com/sezanzeb/key-mapper/discussions/237

This can be solved by a RelToRelHandler on the beta branch. Which already supports different acceleration profiles and different sensitivity.

[sezanzeb]

This can be done on the beta branch now.

If anyone wants to write a small tutorial for https://github.com/sezanzeb/input-remapper/blob/main/readme/examples.md, you are very welcome
