The Cosmos shares many similarities to the Vive, albeit with more attention-grabbing styling. One of the more notable changes to the headset’s facade is the inclusion of a number of extra cameras, necessary for the Cosmos’ inside-out tracking. The change means you can wave goodbye to the fiddly base station setup currently required by both the Vive and the Valve Index.
Once operational external tracking often shows its worth, however – it’s the preferred setup for smooth, accurate operation if you’ve got the space, mounting locations, and time to do so. With that in mind, HTC has announced the very first mod for the Cosmos: the External Tracking Mod. This allows for existing base stations to be used alongside the updated Cosmos design. But you will have to wait until Q1, 2020 for this unit to launch.
