Exploring Body Tracking via Wi-Fi CSI – A Newbie's Proposal

Hi everyone!

I’m new here in the community and I’ve been diving deep into how we can push the boundaries of standalone VR tracking. As a fan of the Quest ecosystem, I’ve been thinking about a challenge we all know: tracking parts of the body that are out of the cameras' line of sight.

I’ve been researching Wi-Fi CSI (Channel State Information) and was wondering if we could use the wireless signal already present in the headset to help with body tracking. Since Wi-Fi signals are affected by human movement (even through walls or behind the back), could this data be used to complement the existing IMU and optical tracking?

The idea would be to use the CSI amplitude and phase changes as a secondary data layer to "guess" limb positions when the cameras can't see them.

I know it’s a technical challenge, but I’d love to hear from more experienced devs here:

Does the current Quest hardware allow low-level access to CSI data for this kind of processing?

Could this be a viable way to achieve "Full Body Tracking" without external sensors in the future?

I'm just starting to develop this concept and would appreciate any feedback or pointers to existing documentation!
