Hmm that opens up a way for cheating in games - have a Screengraber and image processing running directly communicate with mouse and let it calculate the distance to region of interest internally and then give out delta position. For the system, it looks like the mouse has been moved very fast and far

Earlier quoted context omitted.

I bought a K4 Nordic version, only to learn none of their software supports it. So i can't reconfigure the firmware. The keyboard has swapped Super/Alt (Windows/Alt) on the windows layout which is so annoying. I hate spending money on hardware so i'm living with it, but i curse the engineer that burned the prom every day.

That sucks, the main reason I like KeyChron is the little switch on the side of mine that toggles between Mac and Windows! I wouldn't buy another keyboard without this feature TBH.

Yeah on the mac it works fine. The keyboard just shipped with the Left Alt and Left Windows key in the correct positions, but they are mapped opposite in the firmware. Imagine how maddening it was in the beginning.

it's hardly difficult to do that already. Like a Raspberry Pi Pico can be turned into a HID mouse rather easily: https://www.instructables.com/Raspberry-Pi-Pico-As-HID-Mouse...

and yes, hdmi/displayport capture -> ML object detection -> fake HID mouse to cheat is absolutely already a thing.

This would be more exciting if Keychron had mice of more interesting / experimental form factors and functionality. Just like their keyboards, their mice are mostly differentiated by obscure technical features (polling rates!). I'm a bit worried that a decent, modern replacement for the extremely obsolete multi-button mouse I have now (Logitech G602) will never be available.

My G602 died due to Logitech's infamous double-click issue. :(

I've been fine with the G502 X Lightspeed (which should avoid said double-click issue due to optical switches) and some more efficient button use to compensate for the fewer side buttons.

> a decent, modern replacement for...G602

What's wrong with the G502? I like the wired G502 pretty well. Ideally I'd tweak the shape to be a little more like the M500s shape, but I'm happy enough with it overall.

Isn't that just the tact switch failing? Two minute job to replace...

i'm using this mouse for over 2 years now: https://happort.org/mouse

it uses this board: https://github.com/jfedor2/rp2040-pmw3360 and i can dig into my .stl files for the mouse if you want... made it on Blender and https://ryanis.cool/cosmos/beta - it's not the most lightweight thing in the world (would say around 100 grams) but it slides nicely and maybe by cycling/exercising often i don't think this one would give me RSI at any point in time... it's angle based on the most muscle neutral position the human arm anatomy has, between 20° - 30° [0] https://www.jospt.org/doi/pdf/10.2519/jospt.2004.34.10.638

Are you sure you don't have a tiny switch on the side? The manual indicates it should have one -
