Hi everyone, we are experiencing this issue also and would really appreciate a fix.
This thread explains why the trackers may be more succeptible than the HMD/motion controllers:
The Vive HMD and the controllers use an HTC/Valve designed light to digital converter and PBC assembly whereas the Vive Trackers are using Triad manufactured TS3633's as well as a new PBC design. This could explain why they're more susceptible to IR interference than the HMD/controller technology. They fundamentally preform the same function but have underlying differences in design. This may mean that other technologies that will use the TS3633 may also face similar interference issues.
Do you guys know how we might be able to get around this issue with the SteamVR 1.0 trackers, and whether or not this issue will be a problem with the SteamVR 2.0 trackers?
