Hall effect vs? (lemmy.world)

Planning on building a flight stick for a space sim. I understand some basics and I've messed around with an Arduino and a breadboard.

In the planning stages now. Should I measure the axis and rotations on the sim stick with hall effect sensors? Is there a more precise alternative?

I would also like to control the tension on the stick with brushless dc motors like done in this project https://youtu.be/ip641WmY4pA and I think the hall effect shouldn't get interference from the motors. Hopefully.

If you want to use brushless motors for force feedback, you can piggyback the encoding instead of having a separate hall effect sensor. Here's a digikey post about it Link

If you're already going to couple the axes to BLDC motors, why not use the same encoder for position feedback for the motors and the stick?

Hall effect switches on the motors for commutation are accurate, but may not give enough resolution for your application. There are rotational hall effect sensors from AMS that have a LOT of resolution, something like AS5055A might work for your application?
