InertiaCube2 with PPT


I want to inquire on how reliable the IC2 is with the PPTX4 system.

My previous setup was with the IC2 and Ascension Motion Tracking. There was a lot of interference from the FOB ERT black box, which made the inertia cube extremely random and unstable.

For anyone using the IC2 and PPT system together, have you experienced any instability from the IC2 (yaw veers when walking in a straight line)?

The PPT system is an optical tracker, so it won't interfere with the IC2 by itself. However, if you have a lot of magnetic interference in your room, then this can cause problems with the IC2. The IC2 provides the ability to turn off its internal compass which can reduce magnetic interference, but this may cause additional drift.

the ppt systems offer an option for combining optical heading with the InertiaCube orientation tracking. this is a good solution if you have magnetic fields in your room.

the optical heading plugin simply requires two markers in a fixed distance to be placed on the intertiacube. it works reliably in rooms even with strong magnetic interference.

this plugin comes with the PPT system at no extra cost. we can also provide an 'optical heading' marker for this if needed. contact if you need details about this or want to get in touch with other customers who are using this solution.
