Switching multiple trackers with same viewpoint

[MosCao]

Hello all,

I used the search function but could not find any solution to my problem.

For my research project I am using the Oculus Rift DK2 (0.4.4) with Phasespace Impulse X2 Motion Capture System. Three LED markers (front, left and right) are mounted on the Oculus for position tracking. Currently I only use the Front LED for position tracking and the in-built inertial sensor in the Oculus Rift for orientation tracking.
Via vizconnect platform I am able to create a mergedLinkable between these two.
So far, this setup works fine.

However, due to the room size the Front LED happens to lose contact with Phasespace resulting in jumps. In order to make the current system more stable I wanted to integrate the other two LED markers (left and right) as a backup but to no avail. For instance, if the Front LED cannot be localized by the Phasespace System, switch to Left or to Right LED. Hereby, the viewpoint of all three should be the same of course.

Does anyone have any ideas or faced similar issues?

I appreciate any help!

Best regards,
Cao
