HTC Vive System Tracker capacities

Hi, I am developing a AR/VR joint environment between the HTC Vive and Microsoft Hololens, my project centered around using the vive as tracking of objects and sending the info to the hololens, currently I am using the vive controller with the object attached to it. This works wonders, but the problem is the controllers are very bulky and leave a huge footprint and were only using it for tracking and no interaction.

I recently saw that HTC have a new accessories called the "System Tracker"...
