Cheap Full Body Tracking is SMALLER than Ever: SlimeVR Butterfly Tracker Review YouTube video by Jacobfov

Exactly two years ago I uploaded my first video on SlimeVR! Seems like quite a bit has changed since then!

I got @slimevr.dev butterfly trackers working with my #Xbox360, and other consoles.

No mods, just an ESP32-S3 dongle running #JoypadOS, an input routing app, and SlimeVR server running on android.

I made @slimevr.dev trackers flatscreen game compatible. Anybody can easily map out input bindings to any existing game. Check out the video!

Some more progress using @slimevr.dev trackers as a steering wheel! My foot trackers act as gas pedals too!

Decided to see if I can play #Halo with @slimevr.dev #butterfly tracker prototypes. Who says you need to just stick to #VR?

The way I move my body/head controls several controller inputs! I plan to make this work with several game consoles if I can manage it.

Finally got all the tiles made for my #vrtreadmill project. 25,600 6mm balls that allow feet to side on the surface. Next step is to work on the frame that will hold me in place. #vr #vrchat

I've been looking into buying a #VRTreadmill, but after doing research found that using a surface with thousands of balls might be the best route. Building one myself could be cheaper. Goal is to build a solution that costs less than $500 CAD in materials using 25,600 6mm balls and open source.

With the help of a modified @slimevr.dev server it is possible to build a purely IMU based #VR controller.

Testing with a PS5 controller since it allows working on the software implementation first. Hardware eventually?

Solving the #ram crisis with downloadable ram. If all the ram is going to #datacenters, its time to rent their resources directly over the internet.

You know, I sometimes wonder, what's the largest playspace full body tracking can use? 10 meters? 20 meters? An entire house?

How about, infinite playspace using @slimevr.dev's butterfly tracker prototypes and cellular? (Smol slime compatible) #motioncapture #vrchat #butterflytrackers

Add toe tracking support to your VRChat avatar.
Add toe tracking support to your VRChat avatar. YouTube video by Sebrina Rena

I finally have a short tutorial on how to add #toetracking support to your #VRChat avatars. Made possible with a new #unity plugin, and @slimevr.dev compatible trackers.

At some point I need to get in touch with @resonite.com and other platforms about this new tech.

This might be about as advanced as I've managed to get toe tracking in #VRChat with a more #furry styled avatar via @slimevr.dev compatible trackers. Curl, tip toes, and splay. #motioncapture #toetracking www.youtube.com/watch?v=0Zlb...
