JoyShockMapper VS AyaGyroAiming

Here's jsm if you were serious Joyshockmapper

The paper you linked is more of a conceptual explanation for design and implementation of systems into games. To learn how to use JSM itself there is a guide for its functions on its GitHub page. The games database may also provide you with some ready made scripts for you to use and edit to your liking.

There DS4Windows, Steam Input & JoyShockMapper. The easiest way to setup gyro would be DS4Windows, JoyShockMapper would be a involved(relatively) but offers way more customization. You can grab a community config for gyro from steam if you choose steam input.

There's also this https://github.com/Electronicks/JoyShockMapper but i'm not sure if it would work with stadia controllers it might work with the dual shock ones

Non-trackball gaming solution: Use gyro on PS4/5 controller with JoyShockMapper. If flickstick doesn't float your boat, maybe a Steam Controller if you can find one for a reasonable price, with trackball emulation enabled it's basically a thumb ball, and when your thumb gets sore start using gyro.

Is it possible to use gyro aiming + flick stick with any xCloud games, or are we forced to use the analog sticks? I have a PS4 controller (i.e. it has a gyro) and tried using JoyShockMapper, but this doesn't seem to work. It modifies my mouse pointer but not my in-game aiming. Has anyone had success with this or an alternative gyro aiming software package when playing on xCloud? Thanks.

Using the software JoyShockMapper's "motion stick" and the simple config below, I bound pitch and roll to WASD. I was able to just use it exactly like I use the 3DRudder. This software can create a virtual controller, so it is also possible to output analog joystick motion. You can map yaw to something as well, although gyro controllers generally lack a magnetometer and yaw might drift easily.

I have also heard really good things about JoyShockMapper, which is both free and open source.

You don't have to write it, someone already did, using essentially the same method Steam would use. I fail to see how depending on Steam is any different from depending on any other third-party application. You're taking Steam for granted, but it's not as if it's integrated into Windows.

Someone in the Discord is already on it and doing a great job so far! Arthur (Aya CEO) also said in response that the team was planning an official solution. I would assume that's still in the works as well.
